IT1 Development of some efficient THz sources for the spectroscopic applications:

Advancement in nonlinear optical frequency mixing techniques K. Arjun, D. Ganesh and A.K. Chaudhary*

Advanced Centre of Research in High Energy Materials, University of Hyderabad, Telangana 500046, India *Corresponding author: [email protected]; [email protected]

Abstract.The electromagnetic waves having frequencies between 0.1 1012 (i.e. 3 mm) and 10 1012 Hz (i.e. 0.03 mm) is defined as terahertz (THz) radiation. It is a non ionizing and non invasive radiation, therefore, it has find potential applications in homeland security, drugs and explosive detection and biomedical imaging. It can also used to ascertain the water contents in plant and quality of edible items. The illumination of the ultrafast laser pulses on the semiconductor surface is one of the well-known optoelectronic technique used for THz emission. Ultrafast optical excitation of semiconductors for THz generation is governed by two methods (i) the emission from photoconductive antennas (PCA) made of LT/SI GaAs (ii) optical rectification process in nonlinear crystals. Due to rapid growth of molecular engineering and semiconductor technology played very significant role to grow new organic and semiconductor crystals such as ZnGeP2, ZnTe , LAP, BNA, DAST, UOH1 etc. in suitable size . Moreover, these crystal posses very good second order nonlinearity, good transmission in optical and THz range along with high damage threshold. In this paper, I will present different types of phase matching conditions for efficient THz generation using nanoseconds and femtoseconds laser pulses. Efficiency of the generated THz signal also depends on the thickness of the crystal. On one side thick crystal with nanoseconds pulses provides strong generation on other end same crystal with femtoseconds pulses is not suitable for generation of strong signal due group velocity dispersion(GVD).We have made an attempt to demonstrate the effect of GVD in terms of coherence length in ZnGeP2, DAST, BNA and LAP crystals.. The effect of solvent used for crystal growth also affects the GVD which is also discussed experimental and theoretical basis. Finally, I shall show you the time domain spectroscopy of explosives like RDX, TNT, HMX, antibiotic drugs. The generated THz is also employed to assess the quality and strength of natural and commercial rubber sample and effect of organic and inorganic fillers.

IT2 A global quest for an unlimited, sustainable energy source for future generations

Prof. R. Shanker (DST-Ramanna, UGC-Emeritus Fellow & BHU-Distinguished Professor)

Atomic Physics Laboratory, Physics Department, Institute of Science, Banaras Hindu University, Varanasi-221005

Abstract.There has been a global interest to seek an energy source which is unlimited, safe and eco-friendly. This talk is intended to address the same objective with on-going efforts to achieve this goal. A brief account of the type of energy sources that are available to human kind will be given and discussed. The idea of creating a ‘small’ or ‘baby’ SUN on Earth will be discussed at length. The current activities going-on to realise this idea around the world has been initiated by constructing a giant machine called ‘ITER’ which is being installed in southern France. Some important scientific and technological aspects of this machine will be presented and discussed. Related to the functioning of this machine and to the kind of materials to be used in it, a few laboratory research results obtained in our atomic physics laboratory at BHU will be presented [1-2].

IT3 The Smart Materials for Transformation Optics and creating Invisibility: Metamaterials

S.K.Chakarvarti Former Professor and Dean Academic

National Institute of Technology (Institution of National Importance),Kurukshetra-136 119, India Currently, Advisor Research, Manav Rachna International Institute of Research and Studies, Faridabad-121004,

Abstract.Creating effectively invisibility of real things sounds an unusual phenomenon.It is believed that the real future of invisibility lies with a new science, transformation optics. Transformation optics is so called because it is rather like transforming the co-ordinate grid of space. But it doesn't literally do that. Instead, light rays are passed step by step between tiny receivers and transmitters – the "meta-atoms" of the material – in a way that traces out paths rays could never follow in an ordinary transparent material.This is all about controlling the paths of light rays, and it is analogous to the way that light curves when space itself is curved: something caused by strong gravitational fields, as predicted by Einstein's theory of general relativity. The theory was developed in the late 1990s by John Pendry at Imperial College London, and later he and Ulf Leonhardt at the University of St Andrews independently figured out how to use it to make metamaterial "invisibility shields". The idea is that light rays are bent smoothly around an object placed in the centre of a metamaterial shell, and recombined on the other side like water flowing around a rock in a stream. To a viewer on the far side, it's as if nothing has happened to the light during its passage: both shield and internal object are invisible. Electrical engineer David Smith and his team at Duke University in North Carolina worked out how to make a real metamaterial in the late 1990s, using slotted arrays of printed circuit boards on which the metal loops and rings are etched. Because the "meta-atoms" have to be about the same size as the wavelength of the light they are manipulating, this design works for microwaves, not for visible light (which has wavelengths of just a few tenths of a micrometre). In 2006 Smith's group, working with Pendry, unveiled the first microwave invisibility shield: a set of 10 concentric, cylindrical rings of meta-atoms, which could more or less hide an object inside from microwaves. Pendry and his student Jensen Li proposed a simpler design in 2008: a "carpet cloak" that sits on a surface and hides an object under a bump. Here the light can be bent simply by arrays of tiny holes, and researchers at the University of California at Berkeley carved such a microscopic structure out of a silicon chip in 2009. The present talk describes the simple physics and science of Invisibility using metamaterials.

IT4 Understanding the Basic sciences –Physics,Chemistry and Biology of Solids via X-ray

Emission Techniques Daisy Joseph

Nuclear Physics Division, BARC, Trombay, Mumbai-400085

Abstract.Since time memorial it has been shown that any solid can be studied by determining its elemental, molecular and structural composition. All these information can be obtained by using X-ray Emission Techniques consisting of probes such as photons as in XRF (X-ray Fluorescence), protons as in PIXE (Proton Induced X-ray Emission) and synchrotron as in XANES, EXAFS. In EDXRF photon sources are in the form of Radioisotopes such as Fe55, Cd109, Am241. In PIXE we use the FOTIA (Folded tandem ion Accelerator) to extract protons of around 2-5 Mev with a current of around 10 nA to obtain a signature of elemental composition of the samples. In EXAFS a Synchrotron beam of elliptical focussing is used. The beamline has a 460-mm long Si (111) crystal having 2d value equal to 6.2709 Å mounted on an elliptical bender, which can bend the crystal to take shape of an ellipse. I in my talk will summarise how all these probes can be usefully applied to study not only their structure, but also their chemistry (chemical shifts) in definitely shaped solids. In EDXRF and PIXE, a Si (Li) detector, amplifier and MCA is included besides the excitation modes of photons and protons. My talk will elaborate on its experimental methods, results and conclusion in understanding the solids in a variety of applications. A large no of applications have been studied using the above mentioned probes in the following fields of geology, gemmology, rare earths, materials science, bio-sciences and forensic sciences. The following sources were used for characterisation using EDXRF.

For PIXE it was protons of energy from 2-5 MeV extracted from FOTIA,.The talk will elucidate the variety of applications in various fields of science characterising the samples for trace elements down to a few ppm. In synchrotron, chemical shift studies were carried out for 3d elements by seeing the variation of X-ray absorption edge energies of various compounds of the same element. A speciation study of this kind helps in applying to bioinorganic chemistry to obtain geometric structure information on metalloprotein and biomimetic model complex active sites by analyzing the higher energy extended X-ray absorption fine structure (EXAFS) region of the spectrum. In recent years, focus has been on developing methodologies to interpret the lower energy K-pre-edge and rising-edge regions (XANES) and using it for electronic structure determination in complex bioinorganic compounds.

In conclusion it can be said that Although XRF is a physical phenomena involving the interaction of X-rays with matter, most of the applications of XRF are in areas outside of physics (chemistry, environmental sciences, food and product quality monitoring, etc.). My lecture materials will hopefully encourage wider dissemination and use of XRF in undergraduate chemistry and biochemistry programs and demonstrate its potential as a means for teaching concepts such as spectroscopy, sampling, qualitative and quantitative analysis, and elemental composition in, Analytical Chemistry (Quantitative & Instrumental Analysis),Environmental Chemistry, Independent student research projects

Abstract.The behavior of UO2, PuO2 and (U,Pu)O2 nanocrystals at high temperatures can be similar to the behavior of nanoscale grains of the high burn-up structure that forms in the highly exposed oxide nuclear fuels. The bulk nanocrystalline (nc)-oxides (UO2, ThO2), which mimic the high burn-up structure, have been proposed as an advanced fuel [1]. The main advantages of the nanocrystalline fuel are high plasticity, enhanced radiation-damage resistance, and developed closed porosity that can retain most of the fission gases.

It is known that the melting temperatures of nanocrystals can be significantly lowered in comparison with macrocrystals of the same composition. According to experimental data, for the actinide oxides UO2, PuO2 and ThO2 this decrease can amount 300–400 K [2-3]. In the case of uranium and plutonium dioxides, accurate measurements are hampered by the effect of deviation of the nanocrystals from stoichiometry. In this work, the melting mechanisms of stoichiometric (U,Pu)O2 nanocrystals are investigated by the molecular dynamics method. Comparison of calculation results with known theoretical models of nanocrystal melting, such as [4-5] is carried out.

The simulated systems were UO2, PuO2 and (U0.5Pu0.5)O2 nanocrystals with a free surface, isolated in vacuum. The size of the crystals varied from 1900 to 381174 particles. The interaction of the intrinsic ions was described by empirical pair potentials MOX-07 [6], which had been reconstructed from the temperature dependences of the linear expansion coefficient of UO2 and PuO2. The computations were parallelized using the graphics processors. Melting of the model nanocrystals was studied in the time range from 1 to 150 ns.

The melting times and temperatures of the nanocrystals were found to be largely determined by the shape and structure of their surface. Variations in the melting point (Tm) of the magnitude up to 100 K were obtained, depending on the specific number of molecules N in the crystal. The maxima of Tm(N) coincided with the “magic” values of N that corresponded to formation of the crystals of a symmetric truncated octahedral shape. This provided the equality of the Wulff pressures on the (111) and (100) faces. The oscillations of Tm(N) correlated with the number of excess particles at the vertices and edges of the nanocrystal.

Melting of the model nanocrystals always began from the surface. At that, the stability of the “magic” nanocrystals larger than 15 000 particles was determined by the state of the (111) faces. Melting of one of these faces led to irreversible propagation of the liquid phase into the bulk. Smaller “magic” crystals lost stability when

the two adjacent (111) faces melted simultaneously. A single face could melt and crystallize several times until the crystal melted.

At lower temperatures, the melting required random time and was similar to an activation process with activation energies up to 100 eV. The average melting time was an exponential function of the inverse temperature. Thus, for UO2 crystal of 2583 particles Tm corresponding to the simulation time of 150 ns was 135 K lower than the temperature required to melt such crystals within 1 ns. For the crystal of 216102 particles, this difference in melting temperatures became less than 5 K due to increase in the melting activation energy.

As the size of the nanocrystals increased from 2000 to 200000-400000 particles, the melting temperatures increased by 300 K, in good agreement with experimental data. At all sizes of the crystals, an increase in the plutonium content increased the melting temperature, which we attribute to the negative change in the free energy of (111) faces.

New Delhi – 110 067, India Corresponding author: [email protected], [email protected]

Abstract. It is well established that the impacts of energetic ions of energy from a few MeV to few GeV on crystalline or organic materials often induce the emission of UV/visible light from the materials. This process of emission in known as the Ionoluminescence (IL) or Ion beam induced luminescence (IBIL). The analysis of the emitted light provides a better tool for studying the materials phenomena such as ion matter interaction for various properties of materials such impurities, local symmetry of optically active dopants and defects. IL can be used not only for characterization of materials; it can also be applied during materials modifications with ion beams in order to follow the creation and transformation of intrinsic defects. One of the merits of technique is that it can be used together with other ion beam analysis (IBA) techniques such as Rutherford back scattering (RBS), particle induced X-ray emission (PIXE) etc. Nanophosphors exhibits superior properties for the potentials applications in advanced optoelectronic devices such as optical telecommunication, flat displays, white LED’s, lamps displays. A series of investigations on wide range of nanophosphors such as pure and lanthanides doped oxides, silicates, mixed oxy-halides will be presented. Moreover, the important interactions like beam-matter, electron-phonon, ion-ion in the process of defects or dopants induced sensitization/quenching, down-conversion and up-conversion for the advanced applications, such as new flat panel displays with low-energy excitation sources, solar energy converters, and TLD phosphors will also be discussed.

IT9 Influence of Defects on the Diffusion of Helium in Uranium Dioxide: Molecular Dynamics

Abstract.Helium, as an alpha decay product, is one of the main gaseous impurities in nuclear fuel. Its accumulation can lead to the swelling and helium embrittlement processes, which negatively affects the exploitation characteristics of the fuel. Therefor it is necessary to predict the processes of solubility and diffusion of helium in oxide nuclear fuel.

The molecular dynamics (MD) method is an attractive method for studying mass-transport characteristics of the “inert gas – ionic crystal” systems. Numerical simulation allows to completely control such parameters as the absence of impurities, stoichiometry, surface quality, defect concentration, the internal structure of crystallites, etc., which is difficult or even impossible in real experiments. However, previously reported MD results of the helium diffusion coefficients in uranium dioxide [1, 2] are by 4–5 orders of magnitude exceed the experimental ones [3]. However, the diffusion activation energies in both cases are approximately equal.

The reason for this contradiction in diffusion coefficients can be the interaction or association of helium atoms with the crystal defects. The possible defects are anion or cation vacancies, vacancy complexes, and pores. Dislocations and grain boundaries usually increase diffusion rate. In this paper, we study in details the behavior of helium atoms embedded in the uranium dioxide crystal, and their interaction with defects. The calculations were carried out both under the conventional periodic boundary conditions (PBC), and using nanocrystals isolated in vacuum, where the finite size and free surface can be advantages. Parallelization of forces computations on the graphics processors allowed us to simulate crystals of about 20,000 particles during hundreds of nanoseconds, rather than hundreds of picoseconds, as in earlier studies. This made it possible to derive the helium diffusion coefficients reliably and with good accuracy at temperatures of about 1500K. In turn, it allows a direct comparison with the experimental results, and the investigation of mobility and interaction of defects in the material.

A semi-empirical potential for the interaction of helium with uranium dioxide was fitted, based on the experimental data. A comparison with the existing potentials was performed, and it is shown that the helium diffusion does not significantly depend on the interaction potentials. It is concluded that anion and cation vacancies cannot act as the traps for helium atoms, their presence in the simulated system does not significantly reduce the helium diffusion coefficients, and cannot explain such a drastic difference with the experimental results in single crystals.

A method for investigation of helium desorption from nanocrystal into vacuum, similar to experiment, was developed and verified. It is shown that the presence of a void reduces the effective diffusion coefficient by two orders of magnitude, from 1.41E-5 cm2/s for a perfect nanocrystal (1.44E-5 in the case of PBC), to 3.7E-7 cm2/s for a nanocrystal of 20,736 ions with an octahedral pore of 1467 ions, if the desorption curve of helium is fitted by an analytical solution for a defect-free crystal with the interstitial diffusion mechanism. The difference in MD and experimental data may be caused by the defects such as voids or closed pores.

The procedure for calculating the equilibrium solubility of helium in nanocrystals, by the directly dissolution of helium from the surrounding gas phase, was developed. Under 1800K and 1000atm, a solubility value of 2.3E-4 cm3(STP)/g-UO2/atm was obtained.

Abstract. Study of ferrites has always been a topic of immense significance from the point of view of their magnetic applications, including their usage in high frequency devices, microwave devices, bioscience (e. g. - hyperthermia, MRI etc.), switching devices, gas sensing, multi-layer chip inductor etc. For the same, there is a need to understand magnetic properties, and their correlation with structural properties, to be able to have a suitable material for a specific application. Spinel ferrites display face centred cubic (fcc) structure consist of two sub-lattices tetrahedral (A) and octahedral (B). Occupation of ions on site A, B (which affects both structural, magnetic properties) is a complex process, and strongly depends on synthesis process, composition, presence of a particular cation, post-preparation treatments etc. Thus, it is important to obtain proper information about occupation of various cations on A, B site. For this purpose, x-ray diffraction (XRD) is recognized as one of the most suitable, and successful tools for proper determination of cation distribution, apart from neutron diffraction, Mössbauer spectroscopy etc., whereas corresponding changes in magnetic properties can be effectively monitored via magnetic measurements. Currently there is a need to have a simple; cost-effective; eco-friendly technique, to synthesize nano-crystalline spinel ferrites, utilizing suitable cost effective precursors. In this context, green synthesis has emerged as an effective solution, where usage of efficient green precursors (e. g.- banana peel, honey, garlic, ginger, neem (Azadirachta indica) leaves, cardamom seeds, and aloe vera plant extract etc.), acting as chelating agent, stabilizing agent, capping agents can be utilized to have superior yield of nano-ferrites, displaying appropriate magnetic properties. Usage of aforementioned green precursors, for the synthesis (via sol gel auto combustion method) of ferrite nano particles, has the advantage of reduced toxicity of nano-particles, making them more appropriate for bio-medical applications, owing to better biocompatibility. Magnetic properties of ferrites are quite susceptible to particle size, determined by finite dimension effects, is related to reduced number of spins cooperatively linked within the particle, and by surface effects, which become more and more dominanting as the particle size decreases (1 – 100 nm). Under reduced particle size, the properties of nano-materials differ from the properties of their bulk counterparts in spite of the fact that they possess the same chemical composition. Larger surface to volume ratio, and quantum effects are the two important principle factors of nano-materials which cause the magnetic properties of nano-materials to differ significantly from bulk materials, is important in many technological applications. Super-paramagnetism is observed in magnetic nano-particles, and is due to the presence of single-domain in magnetic nano-particles in contrast to multi-domains in the bulk material, especially helpful for biomedical applications of nano-ferrites including magnetic contracts agents in magnetic resonance imaging ‘MRI’, magnetic hyperthermia: for cancer treatment etc. Consequently, present work primarily describes: i) ferrite synthesis, ii) effect of nano size on properties, iii) basic structural (using XRD), magnetic characterization (by means of magnetic measurements), iv) influence of: preparation condition; composition; post-preparation thermal treatments etc. (which can be used to control structural, magnetic properties) on structural and, magnetic properties. Detailed results will be presented.

Abstract.Light emitting rare-earth doped materials have been recognized to hold tremendous potential in the area of optoelectronic and photonic applications, ranging from white LEDs, solid-state lasers, phosphors for color lamps, display panels, optical fiber telecommunications to biomedical probes.The field of light emitting rare-earth doped nanomaterials is of increasing interest in recent years because this leads the way torevolutionary advances in optoelectronics with new classes of materials having new properties and numerous applications. In fact, in the past few years, the interest of the scientific community was devoted to the progress achieved in synthesis, structural characterization and physical properties investigation of rare-earth doped nanostructures. The rare earth ions have a partially filled inner 4fn shell shielded from its surroundings by completely filled outer 5s2 and 5p6 orbital. This shielding results in very sharp optical emissions at wavelengths from ultraviolet to infrared due to 4f-4f or 4f-5d transitions. For the applications, nanophosphor particles should ideally be non-aggregated and of uniform particle-size distribution as shape and size of the phosphor are found to affect photoluminescence (PL) intensity and device efficiency. Several scientific technologies have been developed for the synthesis of the rare-earth doped nanophosphors, including sol-gel process, chemical precipitation method, combustion method, hydrothermal method, solid state, spray pyrolysis method. These light emitting nanomaterials are desirable materials used in display, imaging and lighting applications due to their advantages of superior richness, good chemical and thermal stabilities.

Abstract.Noble metal nanowires have attracted immense research attention owing to their potential technological applications. We study the strain induced magnetism and thermoelectric performance of metallic nanowires (NWs) using first principles density functional calculations. Furthermore, we analyze the thermodynamic properties using quasi-harmonic approximation (QHA), the heat capacity and internal energy for both the NWs originate at 0 K and the internal energy (E) remain high. Our results show excellent stability, colossal magnetism, and thermoelectric properties of given NWs; therefore, these NWs can be used as a potential thermoelectric material for device applications.

Abstract.We are reporting here the synthesis of well-aligned Zn1-xMgxS one-dimensional (1-D) nanorod thin films for visible-light photosensor application. Zn0.8Mg0.2S 1-D nanorod thin films were synthesized by a simple one-step chemical bath deposition technique on a glass substrate for the first time. The electronic structure of ZnS and Mg-doped ZnS thin films were calculated by first principle investigation within the density functional theory. The electronic structure reveals the systematic formation of the intermediate band through Mg substitution in wurtzite ZnS at zinc site. This result is well correlated with the experimental results. The structural results obtained from X-ray diffraction study showed hexagonal wurtzite crystal structure with average crystallite size 23 and 21 nm for ZnS and Mg–ZnS respectively. It is observed from UV–Vis spectra that the energy band gap decreases with Mg content due to the creation of new intermediate bands in the band gap region. Raman spectra obtained from the pure and Mg–ZnS films exhibit the longitudinal optical phonon modes. Photosensing properties of the as-grown ZnS and Mg–ZnS thin films were studied by I-V measurements, the photosensitivity was found to be 92 and 96% respectively..

Abstract.Lately, natural organic nanoparticles with controlled features became prospective for diversified biomedical and pharmacological uses. Interestingly, cinnamon nanoparticles (CNPs) possessing rich active agents of cinnamaldehyde and polyphenols shows effectiveness in favor of nanobiomedicine, especially for antibacterial practices. In this spirit, we prepared CNPs with distinct structures and morphologies in different liquid media (ethanol, methanol and citric acid) with changing laser energies (30, 60, 90, 120, 150 and 180 mJ) via an inexpensive, eco-friendly and accurate technique called pulse laser ablation in liquid (PLAL). In each case, a pure cinnamon target was immersed in the specific liquid medium and ablated by a Q-switched Nd:YAG pulse laser (pulse duration of 10 ns, repetition rate of 1 Hz, wavelength of 1064 nm). As-prepared CNPs were analyzed at room temperature using varied analytical techniques. Influence of altering liquid medium and laser ablation energies on the structures, morphologies, and optical attributes of as-grown CNPs was determined. Furthermore, the antibacterial efficacy of the studied CNPs against Gram-negative and Gram-positive bacterial strains including Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus was evaluated using agar well diffusion assay and optical density (OD600) tests. CNPs grown in each liquid media revealed two prominent UV-Vis absorption bands and one significant PL emission band. FTIR spectra of CNPs displayed the presence of diverse functional groups and bonding vibrations of bioactive components as well as the high levels of pure polyphenols and cinnamaldehyde compounds. TEM micrograph of the optimum colloidal liquid suspension (ablated at energy of 90 mJ) manifested the nucleation of highly crystalline spherical, elliptical and truncated tetrahedral shaped CNPs. EDX spectra of the optimum sample confirmed the existence of exact elemental constituents in protein capped CNPs. Disclosure of sharp peaks in the XRD pattern verified the high crystalline face centered cubic (FCC) structure of CNPs. Meanwhile, LC-MS analyses authenticated the occurrences of various cinnamaldehyde and polyphenolic derivatives in CNPs. These as-grown CNPs with strong light absorption traits divulged excellent antibacterial activity against all the tested bacterial strains. Ethanol medium for CNPs growth was demonstrated to be superior to other media concerning the yield, nanocrystallinities, morphologies, optical characteristics, and bactericidal efficiencies. It was established that the proposed PLAL technique may constitute a basis for the production of CNPs with controlled properties, beneficial for sundry nanomedicinal applications.

The Tail part of the optical absorption (Urbach Energy) is known to provide information about the electronic disorder present in the semiconductor materials. The optical spectroscopy is also predicated to contain the information about the defect state (acceptor and donor level) present within the band gap. Recently we have devised new experimental methodology to probe the defect state if any present in the sample.

Abstract.Structural phase transitions and thermal stability in lead-free layered inorganic-organic (IO) hybrid systems are reported. Copper chloride-based (C12H25NH3)2CuCl4 and (C6H9C2H4NH3)2CuCl4 systems show better stability against copper bromide-based (C12H25NH3)2CuBr4and (C6H9C2H4NH3)2CuBr4 systems. These IO hybrids exhibit multiple solid-solid structural phase transitions depending upon the length of alkylammonium chain and arrangement of metal-halogen network. The estimated decomposition temperatures are 2020C, 1170C, 1870C, and 1020C for (C12H25NH3)2CuCl4, (C6H9C2H4NH3)2CuCl4, (C12H25NH3)2CuBr4,and (C6H9C2H4NH3)2CuBr4, respectively. The optoelectronic and other properties of these materials can be tuned by selecting proper composition of organic and metal halides during solution processed growth.

Abstract. We have investigated the structural phase transition and higher order elastic constants of plutonium chalcogenides (PuX, X=S,Se,Te) using three body interaction potential (TBIP). The three body interaction arises from the electron-shell deformation when the nearest –neighbor ions overlap. This method has been found quite satisfactory in the case of other alkaline earth chalcogenides. The calculated equation of states of plutonium chalcogenides have been compared with high pressure X-ray diffraction data. The theoretically predicted phase transition pressure and other structural properties for these compounds agree reasonably well with the measured values. We have also reported the second and third order elastic constants and second order pressure derivatives. The variation of second order elastic constants (SOEC) is also presented.

Li ion beam irradiation persuaded modifications in the thermodynamic properties of liquid crystalline material 4-n (hexyloxy) benzoic acid (HOBA) have been investigated. The irradiation has been carried out by a pelletron beam using 3 nA current at fluences (1010, 1011, 1012, 1013 ions∕cm2) at room temperature in the crystalline phase of the material. The pure and irradiated liquid crystalline material has a phase sequence of I-N-Cr. The pure and irradiated materials were explored using differential scanning calorimeter (DSC). Thermodynamic studies of the pure and irradiated materials reveal that all the transition temperature is depressed as compared to those of pure materials by the Li ion beam irradiation. The average transition enthalpies and entropies of the irradiated material are increased as compared to those of pure material.

Abstract.Low-cost porous mullite ceramic was prepared by using bauxite and fly ash as raw material. The porous mullite ceramic was fabricated maintaining 80% bauxite and 20% fly ash composition. Compacted samples were heat treated at four different temperature 1300oC, 1400oC,1450oC and 1500oC to study the formation of mullite phase. XRD analysis confirmedthe formation of mullite as a major phase at 1400oC and above. It was found that with an increase in the firing temperature up to 1450oC porosity increases, linear shrinkage decreases and density decreases. After 1450oC normal trend was noticed. FESEM microstructure showed the presence ofdistributed pores, lathe-shaped mullite grains, and the glassy phase. The flexural strength was also investigated to find out the mechanical stability of the porous mullite ceramics.

Abstract.In the current article we report the thermoelectric power factor of aurivillius type, SrBi4Ti4O15 and CuO modified SrBi4Ti4O15. It is found that the addition of CuO increased the electric conductivity and thus the power factor of SrBi4Ti4O15. The importance of exploring this material’s thermoelectric property originates from its layered structure. The layered structure can be viewed as a phone-glass electron crystal.The maximum value of power factor obtained is 6nWm-1K-2at 6000C for CuO modified SBTi. Research on these family of materials need to be pursued in order to obtain improved values of power factor and thermoelectric efficiency.

Abstract.The polycrystalline ceramic samples of YCrO3 and Y0.8Ca0.2CrO3were studied subsequently using powder X-ray diffraction, Raman spectroscopy, X-ray photon spectroscopy (XPS) and impedance spectroscopy measurements to understand the effect of Ca doping on the structural and electrical properties. Both samples were prepared by conventional solid state reaction method. All the samples crystallized in Pnma orthorhombic structure without formation of any secondary phases confirming their phase-pure nature. Rietveld refinement of the X-ray data suggested a decrease in unit cell volume. In Raman, phonon modes shift to lower wave numbers with Ca-doped sample and intensity leads to decrease due to distortion at Y-site. XPS study shows the decrease in binding energy with the Ca-doped sample. Impedance studies showed that the dc conductivity increases while relaxation time increases as Ca-doped in YCrO3. Also, the activation energies decrease with Ca doping.But, both samples indicate an anomaly across ~ 470 K, diffused dielectric transition.

Abstract. In the present scenario, the toughest and intriguing issue is to find a material with a high dielectric constant as well as a low dielectric loss at and above the room temperature. To beat these challenges, the 70%-La0.7Ca0.3MnO3-30%-CoFe2O4nanocomposite is prepared via glycine-nitrate auto-combustion method. From XRD and FT-IR patterns, formation of the perovskite-spinel structure is clearly visualized. FESEM image displays agglomerated grains due to the magnetic nature of the nanocomposite. Impedance and dielectric measurements are carried out in the frequency range 102Hz-106Hz over various temperatures (from room temperature to 100ᵒC). Contributions of diverse nanostructures have been built up by fitting Cole-Cole plot of impedance using R(Q1Rg)(Q2Rgb)(CRin) circuit. Impedance is lowered in a spectacular manner with increase in temperature. Dielectric permittivity increases to the order of 105 in the fabricated system which finds suitability in high-frequency devices.

The β relaxation accompanied with small activation energy is due to the rotational motion of the long flexible side groups/dipoles. As the amount of impurity is increased TSDC current appearing in opposite direction and a new peak appears at higher temperature.

Abstract. In this paper, we theoretically calculate the free exchange-correlation energy fxc of an electron quantum wire in the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land and Sjölander (STLS) approximation. Numerical results of fxc are reported over a wide regime of temperature and electron number density for a fixed wire width. We find that the magnitude of fxc decreases with decrease in electron number density at a given temperature. In order to highlight the effect of inclusion of the dynamics of electron correlations, our results are also compared with the predictions of other static mean-field approximations.

Abstract: Bismuth ferrite (BFO) material has attracted a great interest in scientific research community due their multifarious properties and potential applications in magnetic recording media, solar cell, light-emitting diodes, multifunctional devices, and magnetic memory and spintronics device various due to their wide band gap (2.2-2.8 ev). In the present work, we have synthesized BiFeO3 nanostructures via Co-precipitation method and investigated the effect of annealing temperature on structural and dielectric properties. The structural and morphology study of as synthesized and annealed samples was carried out by using X-Ray Diffractometer (XRD) and scanning electron microscope (SEM). The XRD spectra of all the samples annealed at different temperature revealed that all the peaks correspond to the characteristic peaks of R3C phase of BiFeO3 indicating a single-phase rehombohedral crystal structure of BiFeO3. The dielectric properties of all the samples have been evaluated over a frequency range (5MHz-10Hz) by temperature dependent complex impedance spectroscopic analyzer. Keywords: Nanostructures, Structural, Dielectric properties and complex impedance analysis.

Abstract. In the present work, the effective degradation of a commonly used textile dye methylene blue (MB) in the presence of photocatalyst was investigated under visible light irradation. For this, pd-doped WO3 nanoparticles were synthesized via rapid co-precipitation method. The obtained sample was characterized via powder X-Ray diffractometry for crystallinity analysis and phase structure, SEM for morphological analysis, UV-vis spectroscopy for optical studies. The diffraction peaks obtained from XRD pattern are highly intense that shows crystallinity of the sample (average crystallite size of NPs are ~ 33 nm). The efficiency of degradation of the MB dye in the presence of W(0.99) Pd(0.01)O3 photocatalyst was (~97% in 140 min) with rate constant (~0.021831 퐦퐢퐧 ퟏ). This shows Pd-doped WO3 has high sensitivity to absorb visible light due to its small band gap (Eg~2.45 eV).

Abstract. Organic pollutants such as pesticides, dyes used in agriculture and industries pollute the water on large scale. In order to solve the problem of water pollution caused by the agricultural pesticides its degradation process has been studied. For this purpose, pure-ZnO and La doped ZnO nanoparticles were synthesized via co-precipitation method to observe photocatalytic response. Synthesized nanoparticles were unambiguously examined using x-ray diffraction (XRD) and scanning electron microscopy (SEM) techniques for morphological and structural characterization. UV-visible spectroscopy and photoluminescence (PL) techniques for optical characterization. The average crystallite sizes of ZnO and La-doped ZnO NPs were ~55 nm and 35 nm, respectively. For photocatalytic activity, monocrotophos which is an insecticide is aimed to degrade in normal water under u.v light illumination. Enhancement in photocatalytic degradation efficiency is observed in La-doped ZnO due to enhancement in the surface area.

Abstract.In this paper, we have investigated the crystal structure and electrical behavior of rare-earth (RE) substitute Y0.97RE0.03MnO3 (RE = Sm, Eu) ceramics. All the samples were synthesized successfully by ceramics solid-state reaction route. From X-ray diffraction (XRD) pattern of Y0.97RE0.03MnO3 (RE = Sm, Eu) ceramics, we have found that there is no change in crystalline structure and it was indexed in the hexagonal structure with a noncentrosymmetric space group P63cm. For pristine h-YMnO3, we observed Raman scattering lines at around 151, 305, 460, and 682 cm-1 are of A1 symmetry, those at 410 cm-1 are of E1 symmetry, and the lines at 139 and 219 cm-1 are of E2 symmetry. The modes shifting towards lower wave number are attributed to the fact that the atomic weight of Sm3+ (150.36) and Eu3+ (151.96) is larger than the Y3+ (88.905). Henceforth, there is a signature of a more red shift in the prepared ceramic samples. The values of dielectric constant () for YMnO3, Y0.97Sm0.03MnO3 and Y0.97Eu0.03MnO3 are found 500, 7100 and 6800 respectively.

Abstract:Graphene oxide (GO) has various functional groups attached on their surface which facilities the attachments of other external group through covalent and non covalent substitution. Because of the advantage of chemical method for bulk production, Hummer’s method was used for the synthesis of graphene oxide from the graphite. Functionalization of Graphene oxide was also done using chemical route. The functionalized GO was characterized using various characterization techniques like, X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Thermogravimetric Analysis (TGA). In XRD the diffraction shifting of diffraction peak confirms the functionalization of the GO with nitro aniline. TGA represents the change in thermal stability of GO after the functionalization. It was observed that the thermal stability of GO was improved by functionalization using Nitro aniline.

Abstract. The frequency-dependent dielectric relaxation of ferroelectric BiFeO3-0.30Sr(Fe0.5Nb0.5)O3 (BF-0.30SFN) ceramic, synthesized by solid-state reaction route is studied in the temperature range from 2 K to 300 K by ac-impedance spectroscopy. The x-ray diffraction profile of the powder sample of 0.70BF-0.30SFN at room temperature exhibits coexistence of two phases. The first phase is monoclinic in Cc space group and the second is cubic in Pm-3m space group. The ionic polarization calculated from structural data is found to be ∼ 29.297μC/cm2. The activation energy calculated from the frequency dependence of imaginary part of electric modulus spectra is found to be 0.415eV, which suggests that the bulk conduction in BF-0.30SFN is due to polaron hopping based on the electron carriers. The scaling behavior of the imaginary part of the electric modulus (M′′) suggests that the relaxation describes the same mechanism at various temperatures. The SEM microstructure of this ceramic show the grain size lies in the range 3μm to 10μm and EDS spectra reveals the good chemical homogeneity of the ceramic sample.

Abstract.Various ZnO microstructures were prepared via hydrothermal method using Zinc nitrate as precursor and CTAB as surfactant. Variation in the CTAB concentration resulted in the formation of ZnO microstructures with different morphologies which was confirmed using FESEM analysis. I-V characteristic was used to explore the electrical properties of various ZnO microstructures among which Corn shape exhibited the highest current at +10 V. Light absorption capability of these microstructures were examined via UV-Vis analysis in the range of 200-800 nm and the maximum light harvesting ability was found for corn shaped ZnO microstructures. Thus, we can conclude that corn shaped ZnO microstructures can act as potential active layer for solar cell applications.

The prepared samples were subjected to pre-sintering in a muffle furnace at 800 for 6 hours and thereafter sintered at 900 for 6 hours. XRD analysis confirmed the formation of calcium copper titanate with traces of CaTiO3 and CuO whose intensity increases with Er-Mn substitution. FESEM micrographs show large, regular and polyhedral grains. EDX spectra confirm the stoichiometry of the prepared sample. The dielectric properties were explained on the basis of Maxwell-Wagner model. The prepared sample with x=0.0 and y=0.0 exhibitsthe highest dielectric constant (5190) and low dielectric loss (0.19) at low frequency. Cole-Cole plot indicates that the dielectric properties of the prepared samples mostly come from grain boundary resistance (Rgb).

Abstract. CdS being a member of II-VI group, having a wide optical band gap of 2.42 eV makes it suitable for use in the area of photovoltaic and laser devices. It is normally an n-type semiconductor and by doping it with transition metals one can affect its

optical and structural properties. Present study shows the effect of Fe implantation dose on CdS nanowires. Nanowires were synthesized using track etched filters via electro-deposition technique involving the movement of ions into the pores due to the potential applied with respect to the anode. Synthesized CdS nanowires were implanted with Fe ions at different doses ranging

from E14 to 5E16 using low energy ion beam. Though radiation damage is often considered as an undesirable consequence but in this case presence of Fe has modified the optical properties without effecting the crystallographic orientation of CdS nanowires.

3NIT kurukshetra (Haryana)India Abstract.We examined how to build useful logic functions from the primitive electrical components at our disposal: resistors, diodes, and transistors. We started with primitive diode-resistor logic. This has the serious drawbacks that it is not easy to cascade and an inverter cannot be built in the logic. The introduction of the transistor changed all this, and the resulting diode-transistor logic was a popular implementation technology in the 1950s and 1960s. More recently, it has been replaced by the more efficient transistor-transistor logic. We also covered an important class of transistor structures, the field effect MOS (metal-oxide-silicon) transistors. Logic gates constructed from such transistors are much simpler to analyze than bipolar transistors. Other forms of high-speed bipolar logic gates, such as current mode logic (CML) and emitter-coupled logic (ECL), are beyond the scope of this observation.

Abstract: In this communication, the reflection, transmission and absorption spectra of one-dimensional multilayer periodic structure with alternating traditional dielectric, silicon dioxide (SiO2) and hyperbolic meta-material are analyzed using well-known transfer matrix method (TMM). The hyperbolic meta-material is performed by the plasma and dielectric material. The reflection, transmission and absorption spectra of the HMM at the normal incident with varying effective collision frequency of the plasma is investigated for optical applications. The calculated result reveals that the absorption band at a lower frequency can be found due to a large effective collision frequency.

Abstract: DSSCs based on three different counter electrodes (CEs) viz. platinum (Pt), multiwalled carbon nanotubes (MWCNTs), and mixed Pt/MWCNTs were prepared and their photovoltaic performance is compared. The pastes of MWCNTs and Pt/MWCNTs CEs were coated on indium tin oxide (ITO) glass substrates with doctor blade method whereas the Pt CE is prepared by drop casting method. The structural and catalytic properties of the CEs under reference were investigated by X-ray diffraction (XRD) and Cyclic voltammetry (CV), respectively. Three DSSCs with these three different CEs having ZnO as a photoanode material were assembled in a sandwiched arrangement and the photovoltaic performance of these cells were measured with the help of solar simulator under standard conditions (1.5 Sun, 100 mW cm−2). The DSSC based on mixed Pt/MWCNTs CE exhibited the highest performance (η =3.78%) as compared to the cells based on Pt (η =2.69 %) and MWCNTs (η =2.26 %) CEs which are higher than the DSSCs made with conventional Pt CE.

Abstract. Light as a stream of particles (or corpuscles) along the different lines after originating from source can understood by the specific geometry over space-time around it with periodic condition such that it describes by the string/sound wave differential equation, which determines the electromagnetic wave. Due to the different reported actions about the photon along its travel line with different elementary particles such as atom, electrons etc, it bring to a close that the photon like an ordinary mass particle do have physical observables of different for instance momentum, pressure etc. Within this paper, the photon momentum function other than earlier approach, which either are by using the Poynting’s vector or by using the theory of relativity, is obtain by considering the space-time complex exponential function under the exponential operator subjected to it. The exponential operator over several physical variables of photon is the Taylor theorem for photon which in absence of any material and field space reduces to the space-time variables only.

Fe@Au, Co@Au, Ni@Au bimetallic core-shell nanospheres with different core sizes and shell thickness by using Discrete Dipole Approximation (DDA) simulation technique. It is found that absorption LSPR peaks occur in UV and visible region of the electromagnetic (EM) spectrum. The shifting in LSPR peaks has been observed with the increase of core size as well as shell thickness, whereas, absorption efficiency is found to increase as a function of shell thickness. It is concluded that the absorption LSPR peaks can be tuned by changing core size and shell thickness. Revealed plasmonics properties for core-shell NPs at wavelength of 333-523nm will open the new applications avenues in sensing, imaging, and therapeutics.

Abstract.Surface plasmon resonance (SPR) is a phenomenon that provides tunable control of nanoparticle light absorption and scattering.The resonant metallic nanoparticles have proven to be efficient systems for electromagnetic control at nanoscale also have ability to localize and enhance the optical field via excitation plasmonic resonances. The tunability of plasmonic nanoparticle makes them highly useful in numerous applications such as molecular detection, solar energy devices, cancer detection and treatment. Hybrid nanostructures representing combination of different materials possess properties which are absent in separate components forming the hybrid. These hybrid nanostructures have found applications in photocatalysis, solar cells, plasmon enhanced spectroscopy like SERS, building blocks to construct photodetectors and in biological and chemical sensors. In this paper we summarize the characterization of plasmonic properties of spherical gold nanoparticles dispersed in ZnO matrix and estimation of the dielectric constant of the matrix.

Abstract: Ponderomotive force is a non -linear phenomena experienced by the charged particle when oscillating electromagneticfield of high intense laser interacts with a plasma. This nonlinear phenomena induced by a high frequency field such as generation of magnetic fields in laser irradiated plasmas [1], filamentation [2], parametric instabilities [3], interaction of pulsar radiation with its environment, kinetic processes in solar flares [4] and so on.

In this work, we studied the force induced by profile modification in which the transverse component of the force evolve due to the intensity variation that give rise to the component of non linear oscillating current .This current led to the generation of THz radiation[5]. Results concerning the ponderomotive effects in different plasma are studied. We found that the ponderomotive force is dependent on collisional frequency and magnetic field. Collisional frequency cannot be neglected as it reduces the strength of ponderomotive force. So, we get different values for different plasmas viz. unmagnetised, collisional and magnetized plasma.

Abstract: The effect of Er3+ ions doped alkali boro bismuth tellurite glasses on downconversion properties have been investigated upon 379 nm wavelength excitation and discussed with different concentrations of Er3+ ions. The emission spectra have strong green emission peaks at 524 and 546 nm but the red emission peak at 665 nm disappears in the obtained glass system. Furthermore, the concentration quenching effect have been found beyond 1 mol% of Er3+ ions. The composition dependence of glass transition temperature obtained from the DSC curves implies the increase in the rigidity of the glass network with increasing the Er2O3 concentration up to 1 mol% and thereafter slightly decrease withincreasing the Er2O3 concentration up to 2 mol%. The obtained thermally stable erbium doped glasses seem to be potential candidate for display and photonic devices applications.

Abstract.A WDM system uses a Nortel's WDM System multiplexer at the transmitter to join the several signals together, and a demultiplexer at the receiver to split them apart. With the right type of fiber it is possible to have a device that does both simultaneously, and can function as an optical add-drop multiplexer. The optical filtering devices used have conventionally been etalons (stable solid-state single-frequency Fabry–Pérot interferometers in the form of thin-film-coated optical glass). As there are three different WDM types, whereof one is called "WDM", the notation "xWDM" is normally used when discussing the technology as such. WDM systems are popular with telecommunications companies because they allow them to expand the capacity of the network without laying more fiber. By using WDM and optical amplifiers, they can accommodate several generations of technology development in their optical infrastructure without having to overhaul the backbone network. Capacity of a given link can be expanded simply by upgrading the multiplexers and demultiplexers at each end.

Abstract. Graphene oxide (GO) was synthesized using Improved Hummer’s method at low cost, high yield along with less toxic gases. The chemical exfoliation in the presence of organic solvents such as Dimethyl formamide(DMF), Ethylene glycol(EG), Sodium lauryl sulfate (SLS) and Cetyltrimethyl ammonium bromide (CTAB) was used for the synthesis of functionalized GO. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet visible (UV-VIS) spectroscopic techniques. The flaky texture reflecting layered microstructurewas confirmed for pure and chemically exfoliated GO sheets. The XRD results show that the shift of diffraction peak from 260(2θ) for graphite with interlayer separation of 0.34 nm along the (002) orientation to 10.30 (2θ) has been observed.The d-spacing for GO-DMF, GO-EG, GO-SLS are 0.9967, 0.9879, 0.7522, 1.3905 nm respectively. The results of FTIR show that the graphite is oxidized by strong oxidants and the oxidant atoms are introducedinto graphite layers forming C=O, C-H, COOH and C-O-C bonds with graphene. Also the additional N-H and NH2 groups and reduction of oxygen groups as well has been observed in GO-CTAB.The maxima at 231 nm corresponding to π→ π* transitions of aromatic C-C bonds accompanied with a shoulder at ~300 nm due to n→ π* transitions of C=O bonds has been observed in the optical absorption studies. The degree of GO functionalization can be controlled via either the reactivity of the solvents or the reaction time.

Abstract. The Graphene Quantum dots (GQDs), fragments of graphene have attracted considerable attention in recent years due to the size, edge effects, quantum confinement and heteroatom doping. The doping of graphene based materials can effectively tune their intrinsic properties, including electronic and optical properties, surface and local chemical reactivity. Herein, we present a comprehensive study of ZnO doped GQDs prepared by a facile hydrothermal method by using ZnO and Graphne Oxide (GO) as a source materials. All the synthesized materials were characterized by UV-Visible Spectroscopy (UV-Vis), Raman Spectroscopy, Fourier Transform Infrared (FT-IR) and Photoluminescence (PL). The morphological characterizations were confirmed by transmission electron microcopy images (TEM). The hydrothermally synthesized material had a size of 5-20 nm by uniform doping of zinc nanoparticles on graphene sheet. The results of PL of Zn( II)-GQDs showed a blue to purple emission with the variation in excitation wavelength from 280nm to 380nm. These doped GQDs were found to be an efficient approach with multicolor emission for biological applications and optoelectronic devices to make the environmental friendly, cost effective and easily scalable.

Abstract A new chiral derivatizing reagent, (S)-naproxen benzotriazole ester, has been synthesized and it was characterized by UV, IR, 1HNMR, elemental analysis and polarimetric studies. It was used as a C-N bond forming chiral derivatizing reagent (CDR) for further synthesis of diastereomeric amides of (RS)-salbutamol under microwave irradiation. The diastereomeric pair was separated by achiral phase HPLC using mobile phase in gradient mode containing methanol and aqueous triethylaminephosphate; separation conditions were optimized with respect to pH, flow rate, and buffer concentration and the method of separation was validated as perInternational Council for Harmonisation guidelines. The reagent proved to be very effective for on-line sensitive detection of the diastereomers with very low limit of detection (LOD) values of 0.69 and 0.57 ng mL 1 for diastereomeric derivatives of (S)- and (R)-salbutamol, respectively. The diastereomeric derivatives were separated and isolated by preparative HPLC; these were characterized and were used as standard reference samples for recording 1HNMR and IR spectra for determining absolute configuration and elution order.

Abstract: The application of conductive glass coating in recent years plays a significant role in research and commercial laboratories. We report the change in conducting property of Cu-Ti-C-Cl thin film coating onto glass substrate as a function of atmospheric pressure plasma (Ar+) treatment (upto 15 minutes). This metal-transition metal chloride coating is prepared by chemical solution process where polyvinyl alcohol (PVA) is used as a chelating agent. The UV-Vis absorption spectra reveal that the optical band gap of the thin film varies from 1.71eV to 2.51eV. A reduction in dc static resistance (2.1MΩ to 0.5MΩ) of the film is obtained from the voltage-current characteristics. The X-ray diffraction peak intensity also reduces with treatment time.

Abstract.Polymer composite from biowaste material have gained enough interest by its unique light weight, high strength, high corrosion resistance, affordability, pollution free, renewability and ecofriendly natures. These important factors are relevant to form an energy efficient domain which will boost the fuel economy in many engineering and industrial sectors. In present study, composite material has developed from waste chicken eggshells (CES). Existing hydrophilic semipermeable membrane in eggshell create trouble during the development of composite with hydrophobic matrix. So (CES)/matrix interface was modified by treating CES with sodium hydroxide chemical which better known as “Mercerization”. Structural, morphological, vibrational and mechanical properties were investigated both for untreated and treated CES particle as well as composites. Structural result showed an increase in crystallite size of ESP which indicated the additional crystal growth in crystalline region. A smooth surface with porous membrane were spotted from morphological study. Combinely, porous membrane and crystallite size increment facilitated the interfacial bonding between ESP/matrix which may cause the improvement in mechanical properties of composites.

Abstract: FMLs are laminate structures that consist of alternating layers of metal and composite and are designed to achieve certain properties that exceed those of either constituent individually. The possibility of galvanic corrosion typically prohibits the pairing of carbon fibre and aluminium in a fibre metal laminate. Despite all of the excellent properties of CFRCs, there are issues with using CFRC and metals together. Carbon fibres in CFRPs cause this material to become electrically conductive. The carbon fibres are electrically conductive and electrochemically very noble Therefore, when a metal is electrically connected to a CFRP, it is more susceptible to galvanic corrosion. This situation becomes worse when a large surface area of carbon composite components is coupled to small metallic parts (such as fasteners, bolts and nuts). In these circumstances, the rate of galvanic corrosion is extremely high due to the high cathode. In this present work, study the corrosion behaviour of CFRP type FML and control by the green corrosion inhibitors. These inhibitors could also be extended to dissimilar metal joints made by other fabrication techniques.

Abstract. Softhard (CoFe2O4)x(SrFe12O19)1-x (0.0 ≤ x ≤1.0) nano-composite(s) were prepared by novel one pot reaction sol-gel auto-combustion route and annealed at 800 C for 4 hours. X-ray diffraction (XRD), and vibration sample magnetometer (VSM) were utilized to monitor the effect of substitution on structural, and magnetic properties. XRD confirms the existence of soft (CoFe2O4), and hard (SrFe12O19) phase with average grain size (D) ranging between 57.7 nm to 59.4 nm for hexagonal and 34.6 to 64.5 nm for cubic phase. The magnetization of nano-composites demonstrates hysteresis loop that is characteristic of the exchange coupled system showing structurally two phases, but magnetically single phase. As a result of exchange coupling, between Co, and Sr ferrite enhanced saturation magnetization (70.65 Am2/kg), and remanence (26.29 Am2/kg) were observed as compared to pure SrFe12O19. Observed enhancement in energy product (BH)max (0.83 28.96 kJ/m3) of nano composite also favors good exchange coupling between hard and soft phase.

Abstract In this study low cost biodegradable fillers was incorporated as reinforcing filler into poly(ε-caprolactone ( PCL) matrix by melt compounding (0-35 wt. %) in a twin screw extruder. The prepared biocomposites were investigated for their Thermomechanical, melt rheological, fracture, and crystallization behaviors. The essential work of fracture (we) is reduced on incorporation of GTS while increase in the non-essential work of fracture (βwp) is observed. The composites with 20 wt% of GTS showed 121% increase in the βwp due to reduced interspherulitic region while 35 % decrease in the parameter is registered for highest GTS content (35 wt. %). From the DSC measurements, sharp decrease in crystallinity was observed for all the compositions studied. The crystallization behavior of PCL in presence of varying concentrations of natural fillers ranging from 5 to 35 wt% is also studied. Various crystallization parameters were studied by DSC at four different cooling rates and these parameters were analysed employing Ozawa, Jeziorny and Liu models. Kissinger method was used to estimate the activation energy (ΔE) of the PCL/GTS composites. The ΔE results suggested that the speed of crystallization was inhibited by GTS particles.

Abstract. In the present work we report the effects of 120 MeV 28Si9+ ion beam irradiation on the structural and soft magnetic properties of Fe63.5Cr10Cu1Nb3Si13.5B9 alloy. Structural changes induced by electronic energy losses and associated changes in the magnetic properties were examined using synchrotron x-ray diffraction (SXRD) and room temperature magnetic measurements. SXRD measurements show the broad amorphous hump for studied samples displaying their amorphous nature. Observed variations in the near neighbor distances is indicative of the annihilation of defects that preserves the amorphous nature of the alloy system. Hysteresis measurements confirm moderate changes in coercivity on irradiation up to ion fluence of 1 1014 ions/cm2 , suggesting that Cr based FINEMET alloy can be a potential candidate for their use as core material in applications involving exposure to energetic particle beams and radiations.

At room temperature the sample is polycrystalline with Bi-rich phases,grain sizes are in micron range.Neel temperature (TN) is 371⁰C. Room temperature Raman spectrum showsall 13A1 and E modes and with increase of temperature the modes shift towards lower frequency attaining prominent red shift around TN. P-E loop shows considerable polarizability of the sample.With the increase of temperature,fmax peak position moves towards higher frequency side of dielectric loss (tanδ) spectra.Arrhenius lnfmax(T-1)plot reveals that the sample has an activation energy of 1.11eV for the temperature range of 240-400⁰C. Complex-Zplane plots reveal that the sample is highly resistive at lower temperatures and evolution of semicircles for both grain and grain boundary contributions starts around 240⁰C. The depressed semicircles in Complex-Z and M planesdepict that the sample follows a non-Debye type process.

Abstract.A set of vanado-zinc-boro-phosphate glass nano composites of composition, (B2O3)0.2-(P2O5)0.5-x-(ZnO)0.1-(V2O5)0.2-(Li2O)x; x = 0 to 0.4 have been made by melt quenching method. XRD results confirmed phase formation. Density and molar volume varied arbitrarily with Li2O content indicating drastic structural changes occurring in the samples with Li2O concentration. Changes in dc conductivity with temperature has been analyzed using Mott’s small polaron hopping and variable range hopping models. Activation energy for conduction and density of states at Fermi level have been determined. Observed variations in conductivity and activation energy with Li2O concentration have been attributed to interplay between the polaronic and ionic conductions. Various polaron related parameters have also been determined. Keywords: boro-phosphate glasses, density, small polaron hopping, activation energy, density of states.

Corresponding author: [email protected]

Abstract. A Temperature dependent study of dynamical correlation: velocity autocorrelation function (VACF), power spectrum (PS) and mean square displacement (MSD) of Zr80Pt20 metallic glass at four different temperature(T= 1251K, 1363K, 1490K and 1616K). It has been calculated based on the static harmonic well approximation. The effective interatomic potential for metallic glass is computed using our established model potential with the local field correlation functions (LFCF) due to Hartree (H) and Sarkar et al (S). It is observed that negative dip in velocity auto correlation function decreases as the temperature increases and Sarkar et al produce more negative dip compare to Hartree screening functions. In the power spectrum as temperature increases, the peak of power spectrum moves toward lower ω. The obtained result of MSD concludes that the vibrating component in the atomic motion is decreases as increases the temperatures.

Abstract. The nanoparticles (NPs) of Zn1-xCuxFe2O4 (ZCFO) spinels with x = 0, 0.2, 0.4, 0.6 and 0.8 were synthesized by a sol-gel combustion method using acetate precursor. The synthesized NPs of ZCFO were characterized by X-ray diffraction (XRD) analysis using Rietveld structure refinement. The Rietveld refinement of the XRD patterns revealed that the ZCFO spinels crystallize into diamond cubic structure with Fd-3m space group. The lattice constant and unit cell volume for ZCFO NPs shrink with enhancing doping concentration of Cu2+ ion. The crystalline growth in the NPs of ZCFO was examined by peak broadening present in the XRD pattern. The Williamson-Hall (W-H) plot method was used to study the individual role of crystallite sizes and lattice strain on the peak broadening of the NPs of ZCFO spinels. High-resolution scanning electron microscopy was also done to confirm the particle size. Keywords: “Spinel; X-ray diffraction; Rietveld refinement; Williamson-Hall plot; Nanoparticle”

The prepared samples were annealed at 800°C which were characterized by many complementary techniques. The pure-phase cubic structures in these systems were verified by the powder X-ray diffraction. The average nanocrystalline size has been calculated as 26 and 30 nm using Debye-Scherrer formula and compared with Williamson–Hall analysis. It was investigated that FWHM of diffraction peaks decreases with the doping results in increase nanocrystalline size. The FTIR spectroscopy provides the valuable information and identification of different chemical group/bonds present in the prepared samples. Uv-vis spectroscopy results showed that the Pb2+ influenced the band gap of the host. In the present study, the band gap energy has been increased slightly in Pb2+ doped samples. Also, the shift of the optical absorption edge of undoped sample towards lower energies increases its utilization in the visible region specially photo catalytic activity.

Abstract. Optical glasses with enhanced third order nonlinear attributes are promsing materials for photonic applications, particularly for optical limiting and switching devices. With the aim of obtaining enhanced nonlinear optical (NLO) properties, Eu3+ doped borate glasses have been prepared through method of melt quench. NLO properties of fabricated glasses were investigated using Z‒scan techinique as a function of Eu2O3 concentration at near-infrared (NIR) wavelength (800 nm) by utilising 150 femtosecond (fs) laser pulses generated at a repetetion rate of 80 MHz from sapphire laser. The investigated glasses demonstrated a reverse saturable absorption (RSA) type of behaviour in open aperture (OA) configuration and positive nonlinear refraction in closed aperture (CA) configuration. The retrieved NLO coefficients evidently demonstrate the studied glasses are competing materials for photonic applications under fs regime.

Abstract. (CoFe2O4)x(BaFe12O19)1-x (x= 0.0, 0.4, 0.6, 0.8, 1.0) nano-composites was synthesized via single reaction mixture, utilizing sol-gel auto combustion method, with an intention to have superior structural homogeneity, and eventually to have single magnetic phase with enhanced exchange coupling between CoFe2O4 (soft) BaFe12O19 (hard) phase. As-synthesized composite was thermally treated at 800 C/4hrs, needed for the formation of hexagonal phase. X-ray diffraction (XRD) displays presence of both soft and hard phases only. Grain size for BaFe12O19 and CoFe2O4 respectively range between 50.2 54.5 nm and 45.5 56.5 nm. Obtained value of saturation magnetization (Ms), coercivity (Hc) for the studied samples is respectively: 39.8 Am2/kg 75.5 Am2/kg and 501.2 Oe 2587.9 Oe. Observed Ms, Hc values clearly show that single reaction mixture leads to better exchange coupling between soft-hard phases. Ms enhancement was also observed with increasing substitution amount (x). Observed results point out (CoFe2O4)x(BaFe12O19)1-x composite system as a good candidate for their potential applications as hard magnets.

The temperature dependent conductivity data of the glasses have been obtained using impedance spectroscopy in the frequency range from 10Hz to 7MHz and in the temperature range from 473K to 703 K. Complex Impedance plots suggest the non-Debye nature of relaxing ions. The dc conductivity follows Arrhenius behavior and decreased with increase in PbO content because of increase of network forming PbO4 units, increases the network dimensionality and blocking the migration of mobile ions.

The amorphous nature of the present systems was estimated by XRD patterns. The SEM pattern has been used to study the microstructure of the sample. The effect of temperature on DC conductivity has been measured in the temperature range 523-623K for the compositions. In this temperature range, the DC conductivity increases in MoO3-Bi2O3-B2O3 glasses with increase in MoO3 content whereas it decreases in MoO3-PbO-B2O3 glasses with an increasing MoO3 content which is due to predominantly to Pb2+ ions.

Abstract. Glasses with compositions xM.(40-x)PbO.60B2O3 (M= Fe2O3 and MoO3) have been synthesized by standard melt-quenching technique. The amorphous nature of the each sample was ascertained by XRD patterns. The absorption edge (λcut-off ) shifts toward longer wavelengths with an increase in Fe2O3 as well as MoO3 content in the glass matrix. The Urbach’s energy is used to characterize the degree of disorder in amorphous solids. The values of optical band gap energy for indirect allowed and forbidden transitions have been determined and it was found that it decreases faster in Fe2O3 based samples than the samples containing MoO3 Content. From these results, it was observed that Fe2O3 to be a better probe to generate non-bridging oxygens (NBOs) than MoO3 content in the present study.

Abstract. In this paper, we report the reflectance spectra of hydrogenated amorphous silicon nitride(a-SiNx:H) film grown on GaAs substrate using Plasma Enhanced Chemical Vapor Deposition (PECVD) technique. Fourier Transform Infrared (FTIR) spectroscopy has been used explicitly to resolve the LO and TO phonon mode contributions. The results of variable angle polarized IR reflectance on a-SiNx:H/GaAs samples are obtained for two different orientations. The calculated results for polarized reflectance are in good agreement with experimental measurements by choosing suitable frequencies and damping as fitting parameters.

Abstract. Molybdenum disulfide films were synthesized using drop casting technique. As prepared films were characterized using synchrotron XRD, Raman and UV-Visible spectroscopy. Films were irradiated using Argon beam having energy of 100 keV with electronic energy loss, Se ~ 44 eV/Å. Different fluences varying from 1014 to 1016 ions/cm2were used to irradiate films on the area of 1×1 cm2. Synchrotron X-ray diffraction technique with photons of energy 12.5 keV was used to study the structural changes induced in MoS2 films. An increase in crystallinity was observed for the lowest fluence of 5 × 1014 ions/cm2. Raman spectroscopy was performed to qualitatively determine the defects created using low ion beam. Raman spectrum of sample irradiated with the lowest fluence showed a red shift to indicate the annealed structure of MoS2 film. A blue shift in the Raman modes at higher fluence indicates the strain induced in the film with irradiation.

The organometallic halide perovskite CH3NH3 PbI3 was synthesized from equimolar solutions of the precursors CH 3 NH 3 I and PbI2 in N, N di-methyl formamide (DMF), and its thin films deposited on FTO substrate using spin coating. The CdS films were deposited by chemical bath deposition (CBD) from a solution of CdS in 2-methoxyethanol. The as-deposited thin films were annealed before characterization. The crystal structures of the films were determined by x-ray diffraction (XRD) as tetragonal perovskite (CH3NH3PbI3) and hexagonal Wurtzite (CdS) respectively. The surface morphology of the films was studied by scanning electron microscopy (SEM). The colour of the perovskite thin films was observed to change from yellow to grey with increasing concentration of the precursors in DMF. UV-visible spectroscopy was used to determine the optical band-gap of the materials. The energy gap Eg as determined from the Tauc-plot was about 1.90 eV for the perovskite CH3NH3PbI3 and 2.51 eV for Wurtzite CdS. This value of E g for the nanocrystalline perovskite films is significantly more than the 1.55 eV observed in bulk material. The blue shift occurred may be due to quantum size effects. Keywords:spin coating, hybrid perovskite, nanocrystals, grain size, electron transporting layer.

Abstract: Multiferroics, both ferroelectric and magnetic order coexist, are of great interest because of its potential applications in memory devices, and spintronics. We have studied the room temperature multiferroicity of cupric oxide (CuO) thin film. CuO is non-polar, non ferroelectric material having a monoclinic structure of space group C2/c, which is centrosymmetric. In bulk CuO Dzyaloshinskii–Moriya (DM) ‘cycloidal’ interactions (DM) is responsible for electric polarization. Unfortunately bulk CuO shows an electric polarization in a small temperature window 213K to 230K due to spin spiral. To obtain room temperature electric polarization with sufficiently large value of polarization in centrosymmetric CuO is challenging work. Here we show that CuO thin film has potential to result a large electric polarization (1.92µC/cm2) at room temperature without DM interaction.

Abstract.Cadmium selenide (CdSe) films have been prepared on conducting glass substrates by potentiostatic electrochemical depositionfor the use in solar energy harvesting devices. The effect of deposition potential on the morphological, structural, and optical properties of CdSe films has been examined. X-ray diffraction and Raman spectroscopy confirm the polycrystalline nature of CdSe filmswhich exhibitthe phase shift from wurtzite tozincblendestructure with increase innegative deposition potential. The nanostructured CdSe films possess good optical absorbance in visible spectral region with possible red shift in direct optical bandgap from 1.93 to 1.73 eV with increase in deposition potential due to change in phase and bandgap tuning related to quantum confinement effect. The results suggest CdSeasan efficient absorber material in photovoltaics and photoelectrochemical cells.

Abstract: Sputtered Fe/Nb multilayers were prepared with Nb thicknesses dNb of 35 Å and with Fe thicknesses dFe of 35 Å and sputtered Fe/Nb/Fe trilayers was deposited with Nb thicknesses dNb in the range 50 Å and with Fe thicknesses dFe in the range 120 Å, respectively using high power impulse magnetron sputtering technique. X-ray reflectivity (XRR) measured patterns revealed the high quality of the film structure with a low surface and interface roughness. Nb thin films synthesized with Nb thicknesses dNb in the range 150-700 Å using conventional direct-current magnetron sputtering (CMS) have been compared with those made by high power impulse magnetron sputtering (HIPIMS) operated at the same average power by means of XRR. The obtained XRR patterns were fitted using the Parratt32 software. It was observed that films grown by HIPIMS method have a higher density and interface roughness than that grown by the CMS method. It was also observed that the deposition rate is increasing with the increase of deposition power; it shows linear behavior with deposition power.

Abstract. Nickel oxide thin films were deposited onto glass and n-silicon substrates by rf magnetron sputtering from a NiO sintered ceramic target at RT in pure (Ar) argon atmosphere. The structures, morphology and optical properties of the NiO films were investigated. The X-ray diffraction result shows that the amorphous nature of films deposited on glass substrates and the films deposited on n-silicon substrates have cubic phase with a preferred orientation (200) and polycrystalline nature. The surface morphology of the deposited films consists of closely packed nano-crystals with a diameter in the range of 10-20 nm. UV-visible spectroscopy results showed that the deposited films have good transparency (80–90%) in the visible region and the optical band gap energy was found to be 3.52eV.

Abstract.Electrical transport of the 5d based perovskite SrIrO3 (SIO) films has been investigated. The SIO films of different thickness has been grown by Pulsed laser deposition on SrTiO3(100) substrate. SIO is 5d based Transition metal oxide and exhibit strong spin orbit interaction. SIO is very versatile and its physical properties can be modified with external perturbations. We have perturbed the SIO system by introducing strain in film. Spin orbit interaction determines the transport properties of the SIO. In oppose to bulk SIO, film data shows insulating behavior and resistivity of the thin film increases by increasing film thickness. Temperature dependence resistivity is best fitted with Mott variable-range hopping equation. Atomic Force Microscopy image confirms the layer by layer growth of the film.

2,3,4MepcoSchlenk Engineering College, Sivakasi, Tamilnadu, India Abstract. Laser drilling is a promising way of drilling micro holes over any substrate irrespective of their nature. The reflectivity of the material and the method of ejecting plume is a major factor in laser drilling that makes it unreliable. The plume generated due to this action causes deteriorating effects over the work piece as such affecting surface textures. The removal of the plume is the major consideration in laser machining process, especially in laser assisted drilling. The plume is a form of cluster of ions having charges in it. Due to the magnetic field input, the ions line the path along the lines of force of magnets. Thus, the ion cloud can be cleared at the localized plane, where the subsequent laser drilling going to be happens. The magnetic field study over the ionic plume should be done. Control of flux density with respect to the charges generated should be studied. In this paper, the comparative study of laser drilling with respect to Magnetic field assistant is done. The results show that, at lower laser powers the Taper angle of Magnetic Field assisted laser drilling is minimized and it shows higher Material Removal Rate with better Surface Roughness.

Abstract. Here we synthesized halide perovskite absorber CH3NH3PbI3 and CdS as charge transporting layer for perovskite photovoltaic device. Perovskite absorber and CdS were characterized by X-ray diffraction, UV-Visible spectrophotometry and SEM. The energy gap and structure of CH3NH3PbI3and CdS were found to be suitable foruse as absorber and electron transporting layer in perovskite solar cell device respectively.Numerical simulation of CH3NH3PbI3 perovskite solar cells was then carried out usingthe SCAPS-1D solar cell capacitance simulator software. A perovskite solar cell was simulated forbest efficiency by replacing the traditional compact TiO2 layer with CdS (i.e., a hole-blockinglayer) because CdS layers possess a greater photostability than TiO2 with continuousillumination of sunlight. We investigated the effect oflayer parameters like absorber thickness, bulk defects, and interface defects on the device performance of CdS based perovskite photovoltaic device. It was observed that these parameters have strong impact on open circuit voltage Voc, short circuit current Isc ,fillfactor (FF) and the power conversion efficiency. The device characteristics and optimization of the solar photovoltaic device was recorded and presented in paper.

Thin film is found to be epitaxial to the substrate. Layer by layer growth has been observed with small surface roughness. Magnetization data shows splitting around 60 K, which is due to coupling of ferromagnetic and antiferromagnetic spins at the interface. Small hysteresis in MH data has been observed with a little shift in the loop, which indicates coupling of spins at the interface. Bilayer follows Ohm’s law at room temperature

Abstract. CuS-ZnS nanocomposite films were synthesized through the interaction of H2S gas with nanostructured Cu-Zn films deposited through vacuum evaporation technique at a relatively high pressure of an inert gas. The film samples were synthesized for four different atom% of Zn. XPS analysis showed that both Cu and Zn existed in the +2 oxidation state in the samples. XRD patterns showed that in the samples, CuS and ZnS existed as separate phases and hence the samples were copper sulphide-zinc sulphide nanocomposite films. Also, HRTEM image and SAED pattern of the sample containing the highest atom% of Zn confirmed the co-existence of both CuS and ZnS phases in the sample. The grain size of CuS which was the major phase in the CuS-ZnS nanocomposite films decreased with increase in the atom% of Zn. Red shift of the Raman modes of CuS phase in the samples was an indication of substitutional doping of Zn into the CuS lattice. Analysis of optical absorption and reflection spectra of the samples indicated the possible application of the films as window layer in solar cells.

The surfaces comprises of heights drawn from random distribution, Gaussian distribution, patterned heights and step like structures. The surface morphology of the substrates is analyzed using visibility algorithm. The horizontal Visibility graph captures the differences in the surface morphology of the substrates. The continuous graph is obtained for the substrates formed by heights form random distribution and Gaussian distribution. Whereas discrete peaks in the graph is obtained for brush like and step like morphological features. The visibility algorithm can be incorporated with Atomic Force Microscopic techniques for better understanding the surface features of thin films in general.

Corresponding author: [email protected] Abstract. Organic semiconductors (OSCs) have already used in electronic devices such as organic light emitting diodes (OLEDs), organic field effect transistors (OFETs), and organic solar cells. The organic devices has several advantages: flexible, low cost, fabrication over large surface areas with tunable properties. On the other hand, spintronics is rapid developing area which utilizes the spin degree of freedom of electrons to transfer and manipulate information. It is offering low power and high speed electronic devices. The most successful application of spintronics is the read head in hard disk, leading to an immense increase of the storage density of the hard disk. Recently, the combination of both fields has initiated a new inter-discipline, organic spintronics, to implement the spin functionality in OSCs. A typical spintronic device is the so called organic spin valve (OSVs)consists of two ferromagnetic layers separated by aorganic semiconductor layer . A critical issue in the evolution of these devices is the need to achieve high magnetoresistance. The reproducibility and yield of the vertical OSVs are low and controversial results are found. One of the main factors for which these difficulties come is due to metal penetration from the top magnetic electrode into the soft organic layer-leading to a so-called ill-defined organic spacer layer. This ferromagnetic metal penetration effects lead to the difficulties in fabricating reliable and reproducible OSVs and have been recognized as one of the main factors to hinder the study of organic spintronics.

The present article emphasizes on study of Fe doped modifications in structural and morphological properties of nanocrystalline CdS thin films deposited on glass substrate using cost effective chemical bath deposition method at room temperature. These as deposited and doped thin films were characterized for structural properties using X-ray diffraction (XRD) and Raman scattering techniques while surface morphology observed through scanning electron microscopy (SEM). The XRD analysis revealed polycrystalline nature of thin films having cubic crystalline structure with varying intensity and planar orientations along (100), (101), (103) and (220), on doping slight shift in the peak position along with narrowing of the peaks are observed, while Raman spectra exhibits peak at ~300 and 568cm-1 which on doping shifted to 310 and 572cm-1 respectively. Morphological observations on Fe doping have not shown any major significant effect expect presence of smooth, uniform distribution of crystallites over the substrate surface which in doping samples observed to be agglomerated to form larger grains.

Abstract. In recent years an extensive research is going on developing inorganic semiconducting nano-particle which has promising potential to build up new generation of inorganic-organic hybrid solar cell. FeS2 (pyrite) particle is one of the most attractive and environmentally friendly semiconducting material which has the potential to minimize the fabrication cost of industrial organic-inorganic hybrid solar cells. In this work, FeS2 nanoparticles are prepared by hydrothermal synthesis using capping reagent PEG-400. The microstructure and morphology of the powder is characterized by means of X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), Tauc’s plot etc. The high quality of FeS2 nanoparticle with higher band gap energy (3.19eV) is applied as semiconducting acceptor organic–inorganic based thin film hybrid solar cell.

F31 Carbon Nanotubes - Properties and Applications : A Review

Parveen Kumari Department of Chemistry,College of Basic Science and Humanities,CCS HAU, Hisar- 125004(Haryana)

Corresponding author: [email protected] Abstract: Carbon Nanotubes (CNTs) are allotropes of carbon with a nanostructure having a length-to-diameter ratio apporoximately greater than 1,000,000. CNTs are rolled graphene with SP2 hybridization. These cylindrical carbon molecules have novel properties that make them potentially useful in a wide variety of applications. They exhibit unusual mechanical properties such as high toughness and high elastic moduli. The important aspects of CNTs are their light weight, small size with a high aspect ratio, good tensile strength, and good conducting characteristics. The properties of CNTs are extremely sensitive to the degree of graphitization, chirality and their diameter. CNTs have potential applications in the field of nanotechnology, transistors, actuators, sensors, membranes and capacitors. CNTs behave as ideal one-dimensional “quantum wires” with either semiconducting or metallic properties. The amazing electrical, mechanical, chemical and optical properties of CNTs enable a wide range of other applications such as field emission displays, energy storage devices and drug-delivery devices. CNTs are successfully used in fuel cells for energy storage. Due to their remarkable mechanical properties, CNTs are excellent candidates as reinforcing fibers for different composite materials. The electrical, mechanical and thermal properties of various polymers can be enhanced by incorporating CNTs into the matrix. CNTs interact with the polymer chains and modify the surface characteristics of the polymer matrix (Ajayan & Zhou, 2001). CNT-composite polymers have been used in many different optical applications such as photovoltaic devices and organic light-emitting diodes (Ago et al., 1999; Kymakis & Amaratunga, 2002; Fournet et al. 2001). Conducting polymers have a wide range of applications from the automotive industry to military aircraft.

Abstract: Amongst various metal oxides, Zinc Oxide(ZnO) draws the attention of the scientific community for its various types of properties. For this study purpose, ZnO thin films were prepared by Modified Chemical Bath Deposition (MCBD) technique. To remove out the formation of excessive hydroxide, the bath temperature was maintained at 80oC.There was no change in crystallinity in case of pristine sample. As the annealing temperature increased, the crystallinity goes on improving and then after decreased as it was depicted in the structural morphologies and the variation in the optical properties were also in good correlation with the structural morphologies.

Abstract.In-situ Resistivity, MOKE and XRR measurement has been performed to measure variation of transport, magnetic properties and structural study respectively with Cobalt (Co) film thickness on Poly (methyl methacrylate) (PMMA) thin films. PMMA films were deposited by Spin coating technique. Cobalt thin films were deposited on PMMA using electron beam evaporation technique. It is observed from resistivity measurement that percolation takes place at around 28 Å Co film thickness. Interestingly magnetic dead layer thickness, calculated from MOKE measurement, is 27 Å. In-situ X-ray reflectivity measurement has been done from PMMA and Co/PMMA thin films to characterize structural details. X-ray reflectivity of Co/PMMA reveals that some Co atoms penetrate 25 Å depth intoPMMA at the interface of Co/PMMA which is interestingly same about magnetic dead layer thickness. This kind of behavior implies the magnetic dead layer occurs due to the intermixing of Co into PMMA layer at interface.

Abstract. Numerical diagonalization technique and Monte-Carlo simulation algorithm method is used to study the magnetic properties of spin-1/2 Falicov-Kimball model (FKM) on a triangular lattice. We have incorporated the correlated hopping (t′) term between d- and f- electrons to obtain various interesting ground state magnetic configurations. e.g. long range ferromagnetic (FM) and anti- ferromagnetic (AFM) binary alloy type and segregated phase of localized ( f -) electrons are observed at different values of t′ and One-third filling i.e n = 1/3. Positive value of t′ is observed to drive the system towards phase segregation.

Abstract.The ground state energy and binding energy of a hydrogenic donor impurity 퐷 in a three-dimensional GaAs quantum dot with Gaussian confinement is calculated variationally incorporating the effect of Rashba and Dresselhaus spin-orbit interactions in the presence of externally applied magnetic field. The results show that the Rashba spin-orbit interaction and the strength of the confinement potential reduce the ground state energy of the donor impurity, whereas the magnetic field enhances. It is interesting that the Dresselhaus spin-orbital interaction enhances the binding energy of the impurity in the presence of the magnetic field.

Abstract. We performed ferromagnetic resonance (FMR) to study magnetization dynamics in ferromagnetic/heavy metal bilayers where ferromagnet is Permalloy (Ni81Fe19) and heavy metals are Pt, Ta, and Pd. The bilayers samples were prepared using pulsed magnetron sputtering and were characterized for magnetic properties via FMR. The FMR linewidth varies linearly with the frequency indicating an intrinsic origin of damping. We observe a difference in the value of Gilbert damping constant (α) for different set of bilayers. High value of α for Py/Pt system indicates high spin pumping from Py to Pt compared to Py/Ta and Py/Pd system. The values of 4πMeff are found to vary for different set of samples. We ascribe the slight change of resonance frequencies at the same applied external field is different, may be due to interface quality, placement of sample on the coplanar waveguide, or different magnitude of the external field at the sample etc. Keywords: Magnetic thin films, ferromagnetic resonance, linewidth, Gilbert damping constant etc.

greatly influence the physical properties of Sr2IrO4. Structural investigation has been done using x-ray powder diffraction and Rietveld refinement analysis is employed to deduce the lattice parameter. While there is no structural phase transition but the lattice parameters evolve with Cu doping. Insulating behavior perseveres for all samples but resistivity decreases with increasing Cu content. The decrease in resistivity is due to introduction of electron and the itinerant characters of Cu electrons. The charge transport mechanism is well fitted to two dimensional (D) Mott’s variable range hopping (VRH) model.

Abstract. KBiFe2O5 is a room temperature multiferroic compound with promising dielectric, ferroic and photosensitive properties. It exhibits weak ferromagnetism. In this work we report the temperature dependent magnetic properties such as saturation magnetization, Ms, remnant magnetization, Mr, and coercivity Hc of KBiFe2O5 in a broad range of temperatures varying from 303 K to 823 K. The temperature dependence of coercivity was found to have considerable deviations from the Kneller’s law whereas temperature dependent saturation magnetization showed excellent agreement with Bloch’s law. The results are discussed in terms of inter-particle interaction induced by thermal fluctuation, size distribution of particles and disordered surface spins which influences the surface anisotropy.

Abstract. Nanocrystalline particles of strontium W-type hexaferrites having chemical composition SrCo2AgxFe16-xO27 (x = 0.0, 0.1, 0.2, 0.3) were synthesized by sol-gel technique. The optical and magnetic study was done by using Fourier transform infrared spectroscopy (FTIR) and vibrating sample magnetometer (VSM). The FTIR spectra consisting of absorption peaks within range of 603.9-607 cm-1 confirmed the formation of hexagonal structure for the prepared samples. From the magnetic hysteresis loops, the four magnetic parameters such as saturation magnetization (Ms), remanent magnetization (Mr), coercivity (Hc) and magnetic moment (nB) were calculated. It was reported that saturation magnetization (Ms) and magnetic moment (nB) increases for lower values of silver dopant (x = 0.0, 0.1, 0.2) but for the highest concentration of silver (x = 0.3), values of these two parameters decreases. Also, the values of coercivity (Hc) were found to be in range of 6-54 Oe indicating soft character of synthesized nanohexaferrites. KeywordsNanomaterials; Sol-gel; FTIR study; Magnetic measurements.

Abstract.We have studied structural, magnetic and dielectric properties of Mo-doped ZnCu2Nb2O8 with Mo replacing Nb ion. Here we have prepared polycrystalline samples ZnCu2(Nb1-x Mox)2O8 with x = 0.0 and 0.1. X-ray powder diffraction and allied Rietveld refinement analysis have been used to analyze the structure of the samples. The ZnCu2Nb2O8 shows paramagnetic behavior in whole temperature range. In ZnCu2Nb2O8, Nb+2(S=0) is a non-magnetic site, we have tried to tune the non-magnetic site with magnetic Mo+2(S=1/2). With Mo substitution at Nb-site, magnetic moment decreases and the system remainin paramagnetic state in whole temperature range. Effect of Mo doping shows a structural change in lattice parameters while there is no change in electrical properties as well as in magnetic properties. Frequency dependent dielectric measurement has been done at room temperature.

Abstract. Co2FeAl Heusler alloy was selected as a target to study L21 and XA ordering of atoms by first-principles calculations using WIEN2k code. It has been observed that Co2FeAl (CFA) Alloy tend to form L21 type structure, which is more energetically favorable and much stable compared to XA type structures. Further, we observed that the total magnetic moment Mt (μB/f.u.) shows a strong dependence on site preferences of Fe (Iron) in all available Wyckoff sites. However, this compound does not show a half-metallic character in both type of ordered structures still, it can be used as the spin-polarized material for spintronics application. Our results are opposite to usual site preference rule and approving the validity of Slater-Pauling rule.

Abstract. We perform a variational calculation to obtain the polaronic corrections to the ground state and first-excited state energies of an electron in a two-dimensional parabolic quantum dot of a polar semiconductor in the presence of Rashba spin-orbit interaction for the entire range of electron-phonon coupling constant and confinement length. We also present the results for the bound polaron problem. It is shown that for both the models in the absence of any external magnetic field, first-excited states with non-zero angular momentum get split into two branches for up and down spin of the electron due to Rashba spin-orbit interaction, whereas ground states with zero angular momentum show no spin splitting in both the cases. Application of our theory to GaAs quantum dot shows that polaronic corrections are reasonably large for quantum dots when their sizes are reduced to a few nanometres. But the polaronic corrections remain unaffected by Rashba spin-orbit interaction

The RT crystallographic, magnetic and ferroelectric properties of the ceramic powder prepared by a Columbite method, were characterized by through the neutron diffraction (ND), electron paramagnetic resonance (EPR) and ferroelectric P-E loops measurements. The Rietveld analysis of neutron diffraction data confirm the PFNW exhibits cubic structure with Pm-3m space group and obtained lattice parameters 3.99273 (3) Å. Along with the nuclear crystallographic information,G type antiferromagnetic structure also probed from ND with the propagation vector k = [½ ½ ½]. However, along with the antiferromagnetic (AFM) ordering of the Fe spins, we have observed the existence of weak paramagnetic kind of behaviour at RT through the EPR. The originated P-E loops are not intrinsic nature of the sample, it may be due the magnetization induced ferroelectric polarisation, and it is evidenced through the non – liner slim (relaxor kind) hysteresis loops. By corroborating magnetic and ferroelectric measurements, PFNW can be a RT potential multiferroic.

Abstract.The change in structural behaviour, magnetic measurement & dielectric characteristics of polycrystalline Bi0.90-

xLa0.10HoxFeO3(0.15& 0.15) and labelled as LH15 and LH20 respectively) which were prepared using method of the solid-state reaction, have been investigated. The powder X-ray diffraction and Rietveld refinement of the XRD spectrum indicates that Bi0.90La0.10FeO3multiferroics have single phase in R3c. Rietveld refined spectrum of the XRD conclude that holmium substitution at A-site for the samples LH15 is crystallized as combo of rhombohedral R3c and orthorhombic Pbam space group. Holmium substitution for LH20 has changed the rhombohedral R3c symmetry of Bi0.90La0.10FeO3 to the orthorhombic Pbam symmetry. The magnetic behaviour was studied by recording magnetization with magnetic up to ± 6kOe. Weak ferromagnetic behaviour of all samples attributes that co-doping effectively concealed spiral spin configuration by altering the canting angle. Dielectric behaviour of prepared ceramic compounds was carried by impedance analyser within frequency ranged 100Hz - 7MHz for different temperatures.

Abstract.Spintronics is analogous to electronics, the conventional electronics makes use of the charge property of the electron only, thespintronics devices makes use of the spin property of an electron. The development of spin-based electronics, or spintronics, promises to open up remarkable possibilities. It has been published [1] that manipulating spin is faster and requires far less energy than pushing charge around, and it can take place at smaller scales. Magnetoresistance is the property of a material to change the value of its electrical resistance when an external magnetic field is applied to it. This effect could not lower the electrical resistance of anything by more than 5%. This effect was later termed Anisotropic Magnetoresistance (AMR) to distinguish it from GMR. Spintronics came into light by the advent of Giant Magneto Resistance (GMR) in 1988. GMR is 200 times stronger than ordinary Magneto Resistance. This resulted in the first spintronic device in the form of the spin valve. The incorporation of GMR materials into read heads allowed the storage capacity of a hard disk to increase from one to 20 GB. In 1997, IBM launched GMR heads. Spin-transfer torque is another effect in which the orientation of a magnetic layer in a tunnelmagnetoresistanceorspinvalvecanbemodifiedusingaspin-polarizedcurrent. This resulted in Spin-transfer torque random accessmemory, orSTT-RAM,hasthe advantagesoflowerpower consumptionandbetter scalabilityoverconventional MRAM which uses magnetic fields to flip the active elements. In 2009 - Hitachi and Tohoku University demonstrated a 32-Mbit spin-transfer torque RAM [2]. This article summarizes the past accomplishments, describes some of the major discoveries that will have a lasting impact on the field, and discusses some of the technologies that may revolutionize data storage in the next decade.

Abstract. CaFe2O4 nano ceramics are successfully prepared by green synthesis technique and the obtained nano-sized powder is annealed at 850° C for 6h. The annealed powder is examined by x-ray diffraction (XRD) measurement at room temperature, which confirms that the diffraction peaks of the annealed CaFe2O4 are well crystalline and correspond to post-spinel orthorhombic structure with space group Pnma. Small amount of secondary phase corresponding to CaCO3 has also been observed. Crystallite size and the strain are estimated by Debye Scherrer [46.81 nm, 2.46 × 10-3], Modified Debye Scherrer [50.82 nm, 2.42 × 10-3] and Williamson–Hall plot [81.56 nm, 1.23 × 10-3] respectively. The change in crystallite size and strain seems to be due to the dislocation and anisotropic nature of CaFe2O4 nano ceramics. This indicates that estimation of crystallite size using least squares technique provides more accurate results that can be applied to minimize sources of errors.

Abstract. We have investigated the lattice distortions due to charge and size mismatch in complex oxides (La, Y)1-x(Te4+, Zr4+)xMnO3and its effect on elastic and thermal properties of these complex perovskite manganites. The revealed data on specific heat, thermal expansion, Debye temperature and Bulk modulus studied as a function of lattice distortions using a novel atomistic approach of Atom in Molecules(AIM) theory and Modified Rigid Ion Model (MRIM) are presented for some concentrations (x) of (La, Y)1-x(Te4+, Zr4+)xMnO3 in a wide temperature range. Studied compounds exhibit anomalous increase in Bulk modulus and Debye temperature with increase in doping concentration of tetravalent Te4+ and Zr4+cations at A-site. These compounds give us an unique opportunity to observe the effect of charge and size variance at A-site in perovskite structure without the effect of JT distortions due to occurrence of these compounds in Rhombohedra and hexagonal symmetry with high variance.

Abstract: Fibre metal laminates are hybrid composite materials built up from interlacing layers of thin metals and fibre reinforced adhesives. The FML are used in wide range in aerospace structure and automotive industries application due to their high specific mechanical properties especially fatigue resistance. During the past decades, increasing demand in aircraft industry for high-performance, lightweight structures have stimulated a strong trend towards the development of refined models for fibre-metal laminates (FMLs).The most commercially available fibre metal laminates (FMLs) are ARALL (Aramid Reinforced Aluminium Laminate), based on aramid fibres, GLARE (Glass Reinforced Aluminium Laminate), based on high strength glass fibres and CARALL (Carbon Reinforced Aluminium Laminate), based on carbon fibres. In this present work, study the Mechanical properties and Application of FML.

Abstract. The nanoparticles of LaCr1−xZnxO3 (0≤x≤0.4) have been synthesized through conventional solid state reaction route. The influence of Zn doping in LaCrO3 lattice has been analyzed by x-ray diffraction (XRD) and UV-visible spectroscopy. XRD patterns confirm the formation of single phase samples without any impurity phase. Lattice parameters are determined from Rietveld refinement and the respective unit cell volume for LaCr1−xZnxO3 (0≤x≤0.4) are found to increase with the increase in Zn content. Crystallite size is calculated using Scherrer equation. The optical properties have been analyzed using UV-Visible spectrophotometry techniques in the wavelength region of 200 nm-800 nm. Bandgap energies (Eg) of the samples are found to decrease with increase in Zn content.

Abstract. The studies made in this paper are directed towards displacement and stress analysis of a circular silicon diaphragm to observe the piezoresistive effect for the pressure sensing purpose. The stress produced under low pressure (~ 26 KPa) of dynamic Si diaphragm having circular geometry has been simulated by finite element method (FEM) within the frame work of COMSOL package. According to the simulated results a 50 µm circular Si diaphragm has the vital frequency ~ 350 KHz, which is suitable and produce better, maximum and observable displacement and stress output response and therefore this frequency can be taken into consideration as an exceptional one for piezoresistive pressure sensor.

Abstract.Perovskite structure based lanthanum manganites receive extensive research interest due to exciting physical properties like double exchange interaction, metal-insulator transition etc. We report the structural and transport properties oflanthanum manganite La0.67Sr0.33MnO3. Structural investigation has been done using x-ray powder diffraction and Rietveld analysis for polycrystalline sample La0.67Sr0.33MnO3. Substitution of Sr at La-site inlanthanum manganiteLa0.67Sr0.33MnO3, however, changes the orthorhombic phase into rhombohedral with space group R-3c. Moreover, this material exhibits metallic behavior in whole temperature range. The electrical conduction La0.67Sr0.33MnO3is found to follow power-law behavior with temperature.

We report structural and electronic properties of lithium doped Mg2Si, a known thermoelectric material by first-principle methods. Defect energetics proves to be a key point for optimizing efficiency of thermoelectric materials. We have computedoptimized lattice constant and formation energy for Mg2Si which is in good agreement with literature. Further, the possibility of lithium substitution in Mg2Si at various atomic sites i.e. Mg site, Si site or interstitial 4b siteis consideredbased upon formation energies for the each configuration. The formation energy is leastfor Li substitution at interstitial site which indicates

that lithium prefers to substitute at 4b interstitial site. With the increase in the concentration of lithium at 4b site, bulk modulus decrease and electronic density of states increases which indicates increasein the electrical conductivity of the material. The increase in electrical conductivity enhances seebeck coefficient while interstitial substitution of lithium adds additional scattering centers to atomic vibrations which may lead to decrease in thermal conductivity. Therefore our results indicate that optimized Li intercalation in Mg2Si unit cell can enhance its thermoelectric performance.

Abstract. In the present paper, authors have studied the effect of light absorption and critical beam power on self-focusing of Gaussian laser beam propagating through collisionless magnetized plasma. The field distribution in the medium is expressed in terms of beam-width parameter $f$ and absorption coefficient $ki$. Usual parabolic equation approach under WKB and paraxial approximations is employed to obtain the differential equation for beam width parameter. It is found that critical critical beam power and absorption coefficient play vital role in propagation of Gaussian laser beam in collisionless magnetized plasma. The behaviour of beam-width parameter with the normalized distance of propagation is studied at various values of critical beam power with different absorption levels in magnetized plasma. The results are presented in the form of graphs and discussed.

Abstract. An asymmetric cryptosystem is proposed for securing of double image encryption using hybrid structured phase mask and hybrid mask in affine transform and Fresnel transform domain. The structured phase mask used is a combination of Radial Hilbert mask (RHM) and Fresnel Zone plate (FZP) and the hybrid structured phase mask is a hybrid of phase masks and secondary images after taking Fourier transform (FT) which increases the number of parameters and key length. Hence it helps in enhancement of security against attackers. Affine transform is for inserting randomness in the original images which act as additional key for the proposed work. The encoding and decoding are done by using different keys. The results are carried out by the help of MATLAB R2018a. For the proposed work, Mean Square error (MSE), Peak signal to noise ratio (PSNR) is calculated. The statistical outcome Entropyis also evaluatedwhich ensures that the proposed technique is relevant.

Abstract..Friction stud welding is one the solid state joining process which is produced by means of converting mechanical energy to thermal energy at the interface of the samples by without any external means. Since heat is produced during the welding, the study of thermal behavior on the materials is required. In this paper a one dimensional heat modeling was produced based on the micro annulus approach.The heat flux values are generated by means of heat energy and torque.In this approach on increasing the rotational speed and the pressure the heat values of heat flux increased. Thus the heat flux is proportional to the rotational speed and the pressure. Also the AA6061 and SS304 was welded by considering the indermediate process paprameters like rotational speed, frictional pressure, upsetting time and friction time.The temperature distribution was calculated by means of Finite Element Approach, based on steady and unsteady condition.The heating curves and the cooling curves are to be plotted based on the material properties obtained on steady and unsteady states. The temperature distribution helps to validate it with the experimental values and it is found that the unsteady state condition is more accurate and stable than the steady state condition.Thus the unsteady condition is more suitable and the thermal conductivity of the material plays a major role in the temperature distribution.

Abstract.People all over the world are suffering from tooth ache and other tooth disorders. These problems are very harmful to today’s young children’s due to the contemporary food habits. There are so many advancements in the field of medical science. Still there is a requirement of convenient method for removing the tooth caries from the tooth. The techniques that are conventionally practiced such as removal of the entire tooth for the prevention of further distribution of tooth caries, or drilling out the part of the tooth caries and filling it with amalgam or other tooth pastes will result in lot of heat, noise and vibration in the tooth structure which results in ultimate pains to the patients after the removal of the tooth caries from the tooth even though there is no pain during removal because of anesthesia. In order to avoid these problems, a new technique emerged called as Drill-less dentistry with the aid of micro air abrasion technique. The present work deals with mathematical modelling of dental removal rate in Drill-less dentistry. These mathematical expressions reveal that the enamel and dentin removal rate depends upon the value of mass flow rate of abrasives, velocity of abrasives and density of the abrasives.

Abstract. We studied the structural, energetic and electronic properties of black phosphorene mono layer doped with indium and gallium atom. We replaced a P atom by indium and gallium atom of 16 atom phosphorene mono layer. We found the strong binding of the In and Ga atom with the phosphorene. We suggest that both the atoms are promising dopant. Our results demonstrate that the doped system becomes completely indirect band gap semiconductor with enhanced electrical conductivity. These findings indicate that the In/Ga doped phosphorene can be used as promising material for the gas sensing.

a)Corresponding author: [email protected], b)[email protected] Abstract.The one-dimensional (1D) Aubry-Andree-Harper (AAH) model shows some unique electronic and topological features. It is well known that the diagonal AAH model shows a localization transition at a critical strength of the disorder. On the other hand, recently it has been shown that the off-diagonal AAH model has topologically protected degenerate Majorana modes. It was also shown that to lift this degeneracy one need to introduce cosine modulated diagonal potential term and next nearest neighbor hopping with several adjustable parameters. In this work, we show that similar results can be achieved simply by implementing the off-diagonal AAH model on a binary alloy in 1D. This is a much simpler model which will be easier to implement in an optical lattice experiment. We further show that the Majorana modes remain robust even when the underlying binary lattice is disordered.

Abstract. Electronic and magnetic properties of Aun and Aun-1Li (n=2-6) clusters are investigated using spin polarized density functional theory. It has been found that pure (Aun) and doped (Aun-1Li) gold clusters with even number of atoms have higher chemical stabilities. Au6 exhibits maximum chemical stability due to its highest HOMO-LUMO gap. Further, Au2, Au6, AuLi and Au5Li clusters are relatively more chemically stable than their neighboring ones. Moreover, Li-doping enhances the chemical stabilities of gold clusters which is much pronounced at n=2. It has also been found that magnetic behavior of gold clusters is not affected by doping with Li atom.

Abstract. In this work, we have studied nanoclusters of thorium (Thn) (n=2-6), using first principles calculation by density functional theory. Out of these nanoclusters, the most stable isomer of Th is found to have square bipyramidal structure (Th6(b)). We have also calculated HOMO-LUMO gap (HLG) and chemical hardness of these nanoclusters, which indicates that these atomic clusters are soft. HLG of most stable nanoclusters of Th first increases from 0.29 eV (n=2) to 0.72 eV (n=4) and then decreases to 0.27 eV (n=6). Absorption spectra of these nanoclusters show absorption mainly in infrared and visible region.

Abstract. In this paper, we have symmetrically investigated the structural, optoelectronic and transport properties of bulk Cu2O and Au doped Cu2O structure. The incorporation of Au into Cu2O matrix changes its behavior from semiconducting to metallic behavior. In the DFT calculation electronic band gap of cubic Cu2O is 2.35 eV and Cu2OAu system shows metallic nature. The thermal conductivity of both cubic Cu2O and Cu2OAu are increases with respect to temperature. The cubic structure changed in to tetragonal structure when Au-atom deposited on it. The optical and transport properties of Cu2OAu layers such as absorption coefficient I(ω), reflectivity R(ω) and transmittance, are in good agreement with measured. The susceptibility, thermal conductivity and electrical conductivity shows stable results with variation in temperature and can be utilized energy conversion like solar cell. Our results suggest that the Cu2OAu is a better candidate for potential application for oxide based future bulk/micro/nano scale device.

Corresponding author: a)[email protected] Abstract.Our universe has full of mysteries. The universe is actually an encoded form of information. The universe is a universal language expressing itself. The misery is that the mysteries cannot be easily decoded to understand the laws governing the behavior of the universe. Some parameters are explicit in the universe and they can decode the whole universe. For example, space and time can be treated as the necessary conditions of the universe while mass and energy can be regarded as the sufficient conditions of the universe. All we need to find how to relate all four parameters. This paper will discuss that we can transform any of the four conditions into the rest of the other conditions. The speed is a parameter that relates space with time. The Einstein’s mass – energy equivalence condition can help in the transformation. I will show a space – time – mass – energy matrix can be regarded as mathematical formulation of the transformation.

Corresponding author: [email protected] Abstract.The Holstein–Hubbard model is considered to study the competition between the electron-phonon interaction and the electron-electron interaction in a one-dimensional correlated Fermi systemat half-filling. First, a series of canonical transformations that incorporate phonon coherence and correlation effectsis performed and then the transformed Hamiltonian is averaged with respect to a zero-phonon state. The resulting effective electronic Hamiltonian is finally solved exactly by the Bethe-ansatz technique. It is shown that the present method suggests the existence of a wider intermediate metallic phase at the SDW-CDW crossover region than the one predicted by the simple variational method of Takada and Chatterjee. The presence of this metallic phase is indeed a favorable situation from the point of view of high temperature superconductivity.

Abstract. We have numerically calculated the free exchange-correlation energy fxc of a coupled electron-hole quantum wire system using the finite-temperature self-consistent mean-field theory of Singwi, Tosi, Land and Sjölander (STLS). In both the wires, the quantum confinement to charge carriers is assumed to be in the y–z plane and their motion is free along x-axis. The fxc shows a noticeable dependence on the temperature and particle number density. Our results of fxc are compared with the random phase approximation (RPA) and we find that the magnitude of STLS fxc is small in comparison to the RPA, with a note that this difference is quite significant at low particle number density.

The dispersion equation is solved numerically using MATLAB to find out the propagating modes. Both the growth rate and the real frequency show oscillating nature with the variation of wave number of wave. The instability is due to the initial drift of the particles called streaming type instability. Keywords: quantum, streaming instability, dusty plasma, dispersion.

In the present paper, the contribution of light absorption on self-focusing of cosh-Gaussian laser beams in collisional plasma is studied. The field distribution is expressed in terms of two transverse beam-width parameters, decentred parameters and linear absorption coefficient. Based on parabolic equation approach under Wentzel-Kramers-Brillouin (WKB) and the paraxial approximations, nonlinear differential equations governing the evolution of beam-width parameters are evaluated. The behavior of beam-width parameters with the normalized distance of propagation is studied for di erent values of decentred parameters and absorption coefficients in collisional plasma. The results are presented graphically and discussed.

Corresponding author: * [email protected] Abstract.Due to the increasing energy storage demands, rechargeable non-lithium ion batteries (NLIBs) are becoming popular. However, the key challenge is to search for suitable anode materials for serving as battery components of NLIBs [1]. In this study, we have explored the electrochemical performance of single layer molybdenum sulfo-selenides alloy for sodium (Na) ion batteries using DFT implemented Vienna ab initio simulation package [2] within GGA approximation. Na-ion migration, theoretical capacity and open circuit voltage are calculated with respect to different atomic configurations. The stable adsorption sites of single Na atom are found to be top site of Mo coordinated with 3 S atoms (Site 1), while the least stable is top site of Mo coordinated with 2 Se atoms (Site 6). The various possible adsorption sites are shown in Fig. 1 along with their corresponding adsorption energies.Adsorption of Na atoms on both sides of alloy is considered, where capacity is calculated by adding Na atoms to the sites in descending order of their stability, leading to multi-layer adsorption, and yielding the theoretical storage capacity of 375 mA h g-1, as shown in Fig. 2. The theoretical specific capacity of the anode is calculated using:

Abstract. A two-level system interacting with a phonon bath is studied using avariational method with an improvedtrial wave function. It is shown that our results for the ground state energy are in general lower than those obtained by other similar variational methods. It is also demonstrated that there are two possible ground states for the system, one for smaller values of the tunneling matrix elementand the other for larger values of it and the system undergoes a localization-delocalization transition as the tunneling matrix element is increased beyond a critical value. Though, in general, there is no dispute about the existence of this transition, the nature of the transition is still not very clear. In the present work, we show, in contrast to the other variational results, that localization-delocalization transition is always smooth in conformity the exact numerical results

Abstract. The In this paper we have investigated the stability of 2D monolayer BSb in air, in terms of interaction with oxygen molecule (O2). Present study is based on Density functional theory recommended that O2 molecule could separate to each other spontaneously on the surface of 2D monolayer of BSb, during the dissociation an exothermic process is happened there. The electronic band gap with and without oxygen is 0.31eV (direct) and 0.43eV (indirect). Also, we have investigated optical properties and obtained that in pure BSb higher absorption of photon energy in UV region and oxygen adsorbed BSb also higher absorption of photon energy in UV region. According to this oxidized 2D monolayer BSb is stable after some deformation in structure.

Abstract.Every particle has its counterpart – an anti – particle. Any amount of anti – particle, when in contact with particle, will annihilate itself with particle of the same amount to produce energy in a flash. It is the space – time symmetry that makes particle’s Universe exactly the same as anti – particle’s Universe. On a macroscopic scale, both the Universe pair looks exactly the same. Similar thing happens in microscopic scale, it is the charge symmetry that makes atom and anti – atom exactly the same. The Universe pair and atom pair are observer dependent realism only. An observer made of particle will see exactly opposite to the observer made of anti – particle – the observer pair sees the opposite reality which makes reality as relative. In this paper, I will discuss space – time symmetry on a macroscopic scale and charge symmetry on a microscopic scale.

Abstract. Joining of dissimilar metals by conventional process is not feasible due to several factors like change in mechanical, thermal, chemical and physical properties. Friction welding is a solid state welding method that facilitates dissimilar metals for welding. Besides its vitality in weight reduction, zero requirement of flux and filler rods is certainly advantageous. The heat transfer analysis is the most important aspect in the study of friction welding process because the entire process takes place in a very short time. A good understanding of the heat transfer process in the work piece can be helpful in predicting the thermal cycles of the welding process. Besides, it is useful in predicting the hardness, strength, weld quality in the weld zone and subsequently the weld quality of the joint. This article provides an overview of numerical analysis using various software to simulate the complex joining of dissimilar metals.

Abstract. We investigate the impact of interplay between the contact interaction and the dipole-dipole interaction on the rotational properties of dipolar Bose-Einstein condensate, rotating in an axially confined double-well potential. The dynamics is governed by a quasi-two-dimensional Gross-Pitaevskii equation with phenomenological dissipation and non-local dipole-dipole interaction integral. In the present study, we consider using three different dipolar atoms namely 52Cr, 168Er and 164Dy with increasing order of dipole-dipole interaction strength respectively. We perform a numerical simulation, by allowing the dipolar BEC confined in a double-well potential to rotate about the z axis with an angular frequency. From the simulation, we see, at the critical frequency, the vortex core starts to emerge from the peripheries of the BEC. Further, we observe that the critical frequency of vortex nucleation decreases with an increase of dipole-dipole interaction strength and contact interaction strength and these interactions also enhance the number of vortices. We also find that the increase in average angular momentum per atom with rotational frequency suddenly shifts from linear to non-linear progression after attaining the critical rotational frequency. From the results obtained in the present study, it is quite clear that dipole-dipole interaction and contact interaction compliments with each other, has a considerable influence on the rotational properties of dipolar BECs.

Abstract. We study the DNA breathing dynamics under a periodic forcing by examining the first passage time distribution associated with the bubble lifetime. We consider an overdamped random walk on the Poland-Scheraga free energy landscape in the number of broken base pairs to describe the breathing dynamics. Using backward Fokker-Planck method, we derive analytical closed form expression of the distribution P(푡 |푥 ) of the first passage time 푡 which characterizes bubble lifetime for a bubble of an initial size 푥 . This distribution is examined in details in the limit of small and large bubble sizes. We confirm our analytical predictions by numerically simulating the corresponding Langevin equation which governs the breathing dynamics. We obtain a very good agreements between our analytical predictions with simulated resulted in the appropriate limits. Further, we analyze the effect of forcing on the bubble lifetime and obtain nontrivial scaling behavior of the first passage time distribution which can be verified experimentally.

I45 Quantum Transport in Graphene and Stanene Nanoribbons

a)Corresponding author: [email protected] Abstract.A systematic study of quantum transport using density functional theory combined with non-equilibrium Green’s function method is presented in functionalized graphene and stanene nanoribbons. It is observed that the graphene nanoribbon (GNR) exhibits a conducting (metallic) behavior when the edges are passivated with oxygen (graphene oxide nanoribbon). The quantum conductance in edge oxidized GNR suppressed in both the valance band and the conduction band. Due to the on-site energy difference between the carbon and oxygen atoms, the conductance profile becomes asymmetric with respect to the perfect GNR. On the other hand, the edge oxidized stanene nanoribbon (SnONR) exhibits a semiconducting behavior showing a zero quantum conductance near the Fermi level. The density of states plot in SnONR is completely corroborating the conductance profile. The conductance gap in edge oxidized SnNR is slightly larger in comparison to the edge hydrogenated SnNR. The conductance spectra in both the edge hydrogenated and the edge oxidized SnNRs is asymmetric with respect to the Fermi level due to the on-site energy difference between the oxygen (hydrogen) atoms and the tin atoms at the edges.

The Hubbard corrections were applied to both Zn-3d and O-2p orbitals resulting in improved predictions of properties. DFT+U provides an inexpensive way to accurately reproduce the measured properties as compared to the more expensive hybrid functionals. This plays a huge role in the development of High-Throughput Quantum-Mechanics (HTQM).

Presently, the safety limits for electromagnetic wave exposure above 6GHz are expressed in terms of power density by Federal Communications Commission (FCC). This study estimates the SAR values compliant to mentioned power densities. Inthe numerical scheme, Maxwell’s equation is employed to determine electric field, and SAR is estimated using electric field values. Results show that most of the energy associated with the 5G frequencies is absorbed in epidermis layer of skin tissue. Maximum electric field and SAR values are predicted in skin tissue exposed to 38 GHz radiation, while least electric field and SAR values are found at 60 GHz. 60 GHz can be considered the safest among all three frequencies for 5G mobile communications.

Abstract.We know that everything has a life cycle. All living things, non – living things, countries, world, astronomical bodies, solar system, galaxies, the universe everything has a life cycle. According to Fourier, any physical phenomena can be explained by a sine wave. Any arbitrary signal or physical phenomena is actually a combination of a dc (constant) part, a sin wave with fundamental time period and its harmonics. If we remove the harmonics from any arbitrary signal or physical phenomena, we will be left with only a sine wave of fundamental period. The sine wave of fundamental period possesses over 90% of the signal energy, thus, if we remove all harmonics, we actually do not lose much energy of the signal but we will get the basic shape of the signal or physical phenomena – a sine wave. A sine wave is the basic building block of all physical phenomena including the life cycle of everything from tiny living things to the universe. A sine wave is the ideal shape of any life cycle. Little deviation is allowed by nature to form other shapes from the basic sine wave. These deviation, although very little, can be termed as the effect of imaginary time that introduces unpredictability in the life cycle. The amount of deviation signifies the amount of unpredictability in the life cycle. The amount of unpredictability signifies the amount of imaginary time involved in life cycle. The amount of deviation (amount of harmonics) actually gives different shapes to the different life cycles. But if we do smoothing out the deviations by averaging them, we will be left with a sine wave – basic building block of the Universe.

Abstract. The investigation of Electronic structure of pristine Gallium nitride homobilayer(GaNS2) sheet and the effect of doping with Mn has been done using the spin polarized density functional theory. Also the effect of external applied field on electronic band structure of these pristine and doped nanosheets has been studied. It is found that doping suppresses the energy band gap(Eg) but the extent of suppression is highly dependent on the site of doping. Eg for GaNs2 is 1.857 eV whereas for doped sites i.e g, b, c and n, energy band gaps are 0.245eV, 1.134eV, 1.169eV, and 1.305eV respectively. On applying the external electric field across the bilayer also mutates the HOMO-LUMO gap of individual nanosheets and decrease in band gap is observed on increasing the electric field. Finally, semiconductor to metal transition takes place at critical electric field (EC). EC for GaNs2 is investigated to be 0.8 V/ Å and for sites g, b, c, n values of EC is found to be 1.2 V/ Å , 1.3 V/ Å, 1.4 V/ Å,1.4 V/ Å, respectively. The electric field induced changes in electronic band structure can be utilized in electrical sensor nanodevices and site of doping can be used in engineering desirable band gap according to the requirement.

Abstract. We have performed a detailed Density Functional Theory based first principles calculation to check the effect of Sb doping at As-chain site of the recently discovered 112 (i.e., CaFeAs2) iron based superconductors. It has been observed that As-chain plays an important role to the superconductivity of 112 iron based superconductors which is a unique characteristic of this family. Our density functional theory based electronic structure calculation shows that there is an enhancement of As partial density of states due to Sb doping at As-chain site in rare earth co-doped 112 compounds. Thus, there might be an enhancement of superconductivity due to Sb doping in RE doped 112 superconductors. Further our first principles calculation also reveals the fact that the change in As density of states due to Sb doping for different RE doped 112 compounds is also different. Our results indicate a possible preference of Sm doping over other three rare earth doping with respect to Sb doping at As site for enhancement of superconductivity.

Abstract: Gibb’s free energy difference, Entropy difference and Enthalpy difference are the three important temperature dependent thermodynamic parameters that have been proved to be tremendously advantageous in the study of thermodynamic behaviour of bulk metallic glass forming melts. These three parameters can be calculated with the help of experimental values of specific heat difference between undercooled melt and equilibrium solid phases. But due to the strong tendency of crystallization, it is very difficult to measure the thermodynamical parameters experimentally. As a consequence, theoretical estimation of these parameters becomes highly beneficial. In the present study, Taylor’s series expansion is employed for the computation of thermodynamical parameters of a selected sample of bulk metallic glass (BMG). A comparative study is also prepared between the present study result and the experimental results as well as the results obtained on the basis of various theoretical models. An attempt is also made to correlate the glass forming ability with the reduced glass transition temperature.

Abstract: Ultracold atoms serve as a quantum simulator for many-body physics due to unprecedented experimental control. It will be most interesting when the system is in reduced dimension (in 1D) where the quantum fluctuation plays a major role. In the field of ultracold atoms the inter particle interaction can be tuned to any desired value to reach the Fermionization and Crystallization limit. Fermionization appears for strongly delta interacting bosons (bosons avoid spatial overlap). We also infer the same kind of phenomena with long range interactions, called, crystallization. Here we solve the few body Schrӧdinger equation from the first principle by utilizing Multi Configurational dinger equation from the first principle by utilizing Multi Configurational Time Dependent Hartree (MCTDH-X) method for bosons. We will study how the density and Shannon information entropy evolve for these strongly interacting system. How to distinguish fermionization from crystallization through their many body wave function and how the system goes to the fragmented state from the condensed state has been studied.

Abstract.Modeling, as a substitute for direct measurement and experimentation, is typically used when it is either impossible or impractical to create experimental conditions. Theoretical modeling is a scientific activity or theory designed, the aim of which is to make a particular feature or an entire behavior of experimental evidences easier to understand, define, visualize, or simulate, with the adjusting parameters that it would eventually be able to predict that behavior. It require selecting and identifying relevant aspects and then using different types of models for different aims, such as conceptual models to better understand, operational models to operationalize, mathematical models to quantify, and graphical model to visualize. Furthermore, oxides-based nanomaterials of transition metals like ZnO, NiO, RuO2, Co3O4, MnO2, IrO2, WO3, Fe2O3, In2O3, and V2O5 received considerable attention because of their ability to interact with atoms, ions and molecules not only at their active surfaces but throughout the material. In the present research work, we constructed the visualization of different parameters in terms of crystal structures, fractional coordinates and lattice planes for metal oxides polymorphs (materials with same composition and different crystal structures) particularly ZrO2. By using VESTA (Visualization for Electronic and Structural Analysis) software, we successfully visualized the crystallographic representation of ZrO2 as well as we calculate the Bond length of Zirconium with Oxygen. The calculated bond length is obtained in Angstrom. The structures taken by VESTA software are more accurate and having instantaneous response. VESTA software is portable and free available. The results indicate that using this software, we can easily visualize the crystallographic representation of other oxide-based nanomaterials, which are suitable for various energy, environment and security applications.

Abstract.At present, one of the most widely used medical diagnosis technique is ultrasound imaging which is normally used to visualize internal organs, muscles, or any internal fracture of body. Ultrasound images contain a type of machine dependent multiplicative noise termed as speckle noise, which leads to reduction in image resolution and contrast, which further reduce the diagnostic value of this imaging modality and hampers the physician’s capability to take accurate decisions. The more précised diagnostic information that can be presented in an ultrasound image, the more easier it is to make decision about the plan of treatment. For that reason, pre- processing of an image isvery important to remove such noise. This paper refer toa comparative study of despeckle filters in terms of preserving the texture features and edges for ultrasound images.In the present paper, the performance of despeckle filters is adjudicated in terms of different stabilized evaluation metrics like signal to noise ratio (SNR), root mean square error (RMSE), peak signal to noise ratio (PSNR).

Corresponding author: *[email protected] Abstract.Radon (222Rn) and its decay products are the major source of the inhalation dose received by humans due to natural radioactivity. This environmental radioactivity could lead to significant potential risk for living beings as it includes harmful radionuclides. The present work deals with assessment of annual effective dose rates due to indoor radon and thoron in some of the dwellings of Punjab. The equivalent dose rate to lungs (H) due to indoor radon has also been estimated. The indoor radon concentration varies from 18.3Bq m-3 to 122.2Bq m-3 with average value of 63.86Bq m-3. The thoron concentration varies from 23.3 to 172.2Bq m-3 with average value of 89.45Bq m-3. The average values of annual effective dose due to radon and thoron are 1.847 mSv and 2.25 mSv respectively. The higher values of thoron may be due to the higher amount of Thorium (232Th) present as compared to the Radium (226Ra). Equivalent dose rate to lungs varies from 14.64 to 97.8 nSv with average value of 51.15 nSv. The mean value of the inhalation dose from 222Rn and 220Rn in the study area is less than the world’s average mean inhalation dose for 222Rn and 220Rn. Therefore, the health hazards related to radiation are expected to be negligible in the studied area. Keywords: Pin-hole dosimeter, Indoor 222Rn and 222Rn, Annual effective dose, Lungs.

Radon migrates and appears predominantly by diffusion process. 222Rn decays from radium in underground soil and building materials like bricks, stones, cement etc. Radon, thoron and their short-lived decay products in indoor places are recognized as the main sources of public exposure from the natural radioactivity. They are contributing to nearly 50% of the global mean effective dose to the general public. The decay products of radon can attached to surface of aerosols, dust and smoke particles which may be inhaled become deeply trapped in the lungs.

Abstract. In the present work, we study the interaction of gamma-rays with oxides of lanthanides, namely lanthanum oxide (La2O3) and europium oxide (Eu2O3). Variation of mass attenuation coefficient values with gamma-ray photon energy is calculated using WinXcom software package in the energy range 1 keV to 103 MeV. The total mass attenuation coefficient values are further used to assign the effective atomic number Zeff and the electron density Ne for these lanthanide oxides. The results obtained for effective atomic number are also compared with the experimental data.

The shielding properties have been evaluated using both Hubbell and Seltzer and Boone and Chavez database with the help of XCOM and XMuDat programs. Shielding ability from gamma rays has been assessed from several parameters including mass attenuation coefficient, tenth-value layer, effective atomic number and effective electron density. As compared to the common nuclear reactor shielding concretes (ordinary and barite) and commercially available shielding glass RS 360, our studied glasses have provided much better results. Low values of exposure buildup factor indicate good shielding behaviour of the glasses. The glasses also have superior neutron shielding properties than the commonly used neutron shields (Boron Carbide, Polyacrylic Acid and Graphite). The investigated glass system require lesser volume for shield design owing to its better gamma-ray and neutron shielding properties as well as transparency to visible light. The investigated Sb2O3-based multicomponent heavy metal oxide glasses have the potential to be utilized as transparent see-through radiation shielding material in several nuclear and medical applications to shield the radiation workers from excessive radiation exposure.

Abstract.Polymers doped with heavy metal oxide are proposed to shield the radiation workers from hazardous gamma-rays and neutrons originating from nuclear reactors, high-energy physics labs, medical radiotherapy units, academic research facilities etc. In this work, polymethyl methacrylate (PMMA) matrices doped with neodymium oxide were studied and an extensive evaluation of their gamma-radiation and neutron shielding ability was done. The gamma-ray shielding properties of the polymer matrices were evaluated by Hubbell and Seltzer database using XCOM. Different parameters including mass and linear attenuation coefficient, half and tenth value layer and mean free path were assessed. In addition, the neutron shielding properties were assessed from the fast neutron removal cross-sections. Gamma-ray shielding properties in terms of mean free path for photon energies 356 and 662 keV came out to be superior to the ordinary concrete and commercially available shielding glass RS 253. The polymer matricesalso have better neutron shielding properties than the commonly used neutron shields such as Boron Carbide, Polyethylene grains and ordinary concrete. The studied light-weight and flexible PMMA matrices doped with neodymium oxide can serve as protective gamma-ray and neutron shields for the personnel involved in radiation applications.

a)Corresponding author: [email protected] Abstract. For photon energies below 1 Mev the predominant phenomenon involved are photoelectric absorption, coherent scattering (Rayleigh) and incoherent scattering (Compton). Biological samples with small thickness attenuate the transmitted beam very little and the application of transmission technique is not possible, when atomic number variations are more significant. Indeed, the Rayleigh to Compton scattering ratio enables material to be characterized only by its atomic number, independent of the material density or of the attenuation inside the tested object. Hence evaluation of the parameter “effective atomic number” is still necessary to characterize the measurement sensibility and to establish a correlation with the estimated Rayleigh to Compton scattering ratio.

Abstract. Mass Attenuation Coefficient of X-rays have been determined for the ayurvedic Nano-medicine (Kasisa bhasma) of three brands in the X-ray energy range from 17.78 to 44.216 keV by employing good beam transmission geometry using the NaI(Tl) scintillation X-ray detector. The variation in X-ray mass attenuation coefficient (decreasing) with incident photon energy (increasing) was noted. And the XRD analysis confirms the crystalline nature of the nano-medicine with particle size ranging from 38.31 nm (for DKB) and 49.86 nm (for VKB) to 52.75 nm (PKB). Also we observed that, as the sample particle size is increased there is increase in value of mass attenuation coefficient of X-ray, this clearly reflects the mass attenuation coefficient values strongly depends on size of particles of the sample.

Abstract. Number of different particles (electrons, photons, pions, protons, deuterons, etc.) are emitted during photonuclear reaction. Some of these particles hit the RANGE telescope and stop there depending on their initial energy and thickness of the detector segment. In the segmented detector, usually, different particles can be identified by looking at the energy deposited in a thin (E) detector segment compared with the total energy E of the particle. Such a plot, known as aE vs. E or stopping power plot which shows different bands for different types of particles. This occurs because the rate of energy loss of a particle depends on the mass and energy of the particle.

Abstract. Fly ash, which is the combustion of coal, is an important by product of coal, which produces by burning of coal in power plants. It contains a significant amount of radionuclide abundance viz. Uranium, thorium and potassium. It is very important to study consider significant health hazard imposed in human beings due to large number of amount of fly ash used in making bricks and cemented road now a days. In thepresent study radon exhalation rate measurement has been done using CAN technique (based on solid state nuclear track detector). A total no. of 16 fly ash samples collected from dumping areas of Kasimpur Thermal Power Plant ,Harduaganj, Aligarh has been analysis using passive detector. For the measurement of the radon exhalation rate, the 'CAN technique' using alpha sensitive LR-115 type II plastic track detectors were used. Measured value of radon mass exhalation varies from 0.31mBq/kg/h to 2.31mBq/kg/h with an average 1.18mBq/kg/h. The radon surface exhalation rate varies from 7.78mBq/m2/h to 57.7mBq/m2/h with an average 29.5mBq/m2/h. A significant amount of radon exhalation from flyash samples seems to emphasize the needed for adequate facilities require around dumping areas and minimize the effect on health effects by reducing of the amount of radon and its progenies.

Abstract: Uranium and radium are the naturally occurring radioactive elements present in earth’s crust which on decay leads to radon and thoron gases in indoor and outdoor environment, soil and water. These gases further decay and decay products are harmful as well. Radon, being a naturally occurring radioactive gas can cause many health related malignancies to humans who have continuously exposed to its radiations. Radon is considered a significant contaminant that is second most frequent cause of lung cancer after cigarette smoking. Due to these health-related issues a lot of work has been done to find out its levels at various places in the world by different research groups. The present work deals with assessment of annual effective dose rates due to indoor radon and thoron in some of the dwellings of Punjab. It has been shown that the higher radon concentration is 303.37 Bq.m-3 and lowest is 53.72 Bq.m-3 with the average value of 155.47±65.38 Bq.m-3. Surface exhalation rate in soil samples varies from 5.16 mBq.m-2.h-1 to 29.14 mBq.m-2.h-1 with the average value of 14.93±6.28 mBq.m-2.h-1. Mass exhalation rate in samples varies from 1.25 mBq.kg-1.h-1 to 7.04 mBq.kg-1.h-1 with average value of 3.61±1.52 mBq.kg-1.h-1. The mean values of radon concentration and exhalation rates are nearly the same and less than the world wide average. Therefore, the health hazards related to radiation are expected to be negligible in the studied area.

Abstract.The dynamics of Acrylamide-co-Sodium acrylate hydrogels with the variation in sodium acrylate (SA) content was investigated by partial heterodyne approach using dynamic light scattering. It was seen that with the addition of hydrophilic sodium acrylate into the polyacrylamide matrix, the extent of frozen in structure and fluctuations is reduced. Also the spatial inhomogeneities in the network was greatly suppressed as a result of rise in SA concentration. Cooperative diffusion coefficient decreased which may be attributed as the decrease in crosslinking efficiency of crosslinker with the addition of sodium acrylate.

Abstract.The dynamical behavior of charged poly-acrylic acid solutions is investigated in the presence and absence of electrolyte using dynamic light scattering measurements. An interesting non-ergodic to ergodic transition is observed for polyelectrolyte solution with addition of excess salt. Our study shows two modes of diffusive processes that are greatly influenced by inter-molecular interactions occurring inside the charged polymer systems, which in turn affect the correlation length and thereby showing changes in structural behavior of the polyelectrolyte solutions.

Abstract. Polymer dispersed liquid crystal (PDLC) is a striking material and have an enormous role in electro optic display devices. In this paper, nanoparticles (NPs) doped PDLCs in normal mode were prepared from a mixture of UV curable liquid polymer, nematic liquid crystal (LC) and silica NPs by the polymerization induced phase separation (PIPS) process. Morphological study shows the LC droplets cluster formation in pure PDLC and LC droplets with a more uniform phase separated polymer matrix in NPs doped PDLC due to the heterogeneous nucleation rate caused by the increased nucleation at the surface of NPs. Further, electro optic properties of doped and pure PDLC including transmittance, driving voltage, contrast ratio and sharpness as well as slope of the linear region of the transmittance-voltage were measured, compared and analyzed. Driving voltage of NPs doped PDLCs quite improved, however the slope of linear region and contrast ratio declined as compared to pure PDLC.

Abstract. Metal-polymer composite filmsare prepared by depositing copper over the polystyrene films. DC magnetron sputtering is used to deposit copper, whereas spin coating method is used to prepare polystyrene layer on glass substrate. The crystallinity of the composite samples is studied using X-ray diffraction (XRD) method.Surface morphologies of the composite films are obtained from Atomic Force Microscopy (AFM), while the optical absorption behaviors are analyzed using UV-Vis spectroscopy. The electrical behaviors of these composite films are measured as a function of the deposition time of the sputtered copper layer over the polystyrene films. Results obtained from the XRD, AFM and UV-Vis spectroscopy provide the evidence of copper nanocrystals formation and from the electrical measurements, it is observed that the conductance of the composite film increases with the increase of the amount of copper nanoparticles inside the composite films.

Abstract. Micelles with different symmetries have immense applications on cosmetic formulations, oil recovery, drug delivery and so on. To understand the controlling factors responsible for shape transformations of micelles and to achieve the relevant time and length scale, a multi-scale approach is used where an all atomistic simulation is employed to derive a coarse-grained (CG) model for the micelles. Cationic surfactants, behenyltrimethyl ammonium chloride (BTMAC) in water self-assemble into a cylindrical micellar phase which transforms into a spherical micellar phase upon addition of a co-surfactant, stearyl alcohol, SA. The bonded distributions of the CG model are derived by the canonical sampling of their respective AA simulations. Martini non-bonded potentials are found to be suitable to obtain the cylindrical micellar phase as in the AA model for BTMAC/water system, but not for the mixed system. Parameterization of martini force field enables to obtain the size distributions of the spherical micelle consistent with the AA ones. Our simulations reveal that a correct interplay between the head-group size and hydrophilicity is crucial for obtaining the micellar size distributions. Thus, the current study provides insights on the controlling factors of the cylindrical to spherical shape transformations of the micelles and shows the suitability of multi-scale ansatz to achieve the relevant length and time scale, inaccessible to the experiments, otherwise.

Abstract. Effect of dichroic dye on nano particles induced homeotropic aligned liquid crystal (HALC) cells was studied for an enormous approach in display technology. The measurements of absorption coefficient and electro-optic (E-O) performance of HALC cells doped with two different concentrations (wt. /wt. ratio) of 0.25% and 0.5% of dichroic dye reveal that higher dye concentration lowered the values of threshold as well as operating voltages. However, contrast ratio (CR) and absorption coefficient (β) have been found to be reduced with higher dye concentration due to increase in off state transmittance.

Abstract.Presented work reports the effect of ultrasonication time (30-80min) on colloidal structure of different shapes of CuO nanoparticles (spherical, cubelike, rectangular, nanobar, nanorod) in Ethylene Glycol (EG): Distilled Water (DW) (70:30) ratio for 0.3 vol. %. The ultrasonication technique is used to prepare the mixture of nanofluid and resulted nanofluid show the particle stability in convectional fluid and thermophysical properties determine enhancement in results which mainly depend on sonication time and the energy supplied to the mixture. The colloidal suspension is shown by microscopic images of different size and shaped particles are shown in TEM images. Zeta potential is measured to check the stability of different shaped CuO nanoparticle suspended fluid with changing sonication duration. The thermal conductivity is calculated from Bridgman equation, and viscosity is also measured for all shaped colloidal solution. Here, all characterization is done after ultrasonic treatment for different time duration ranging 30-80 min. Better particle dispersion, smaller aggregation, less precipitation, and higher zeta potential values are observed with increasing sonication time. Hence, thermal conductivity enhancement and decreasing nature of viscosity is obtained for increasing sonication time, which may have implications on the heat transfer application.

Abstract. Fe1-xNix (x=0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.9) alloys have been prepared by arc melting method and were investigated using X-ray diffraction (XRD), Resistivity and magnetic measurements. XRD studies indicated a structural phase transition from bcc to fcc in the alloys system. The alloys upto x=0.2 possess bcc structure and that with x > 0.3 possess fcc structure. Filed dependent magnetoresistance (MR) was obtained from the resistivity measured at 5K with and without a longitudinal magnetic field of 8T. The field dependent magnetoresistance is positive for x=0.1, 0.7 and 0.9 alloys. The MR exhibited by x=0.2 and 0.5 is negative but very small whereas the x=0.4 invar alloy exhibits a large negative MR. The saturation magnetization was found to be same at 300K and 5K temperatures for all the alloys except for 0.4 alloy which exhibits more saturation magnetization at 5K compared to that at 300K. The magnetic and MR behaviour of x=0.4 invar alloy at low temperatures suggests the formation of re-entrant spin glass (RSG) phase. The linear dependence of MR in the invar alloys indicates spin disorder scattering.

Abstract:-Here we report the synthesis of Al0.492Cr1.133 Fe0.78 Mg0.499 Ni0.007 O4 Si0.001 Ti0.082 Zn0.005 (chromite) using a wet chemical approach i.eCoprecipitation method. The prepared powdered composite was structurally characterized through X-ray diffraction analysis. The XRD data was refined by MAUD and Fullprof suit software. Rietveld analysis based on structure and microstructure refinement has been used for precise determination of many microstructural parameters such as Wyckoff positions, intensity, Miller indices value, and interatomic distance. X-ray diffraction and Rietveld analysis shows that prepared sample of composites has a single cubic phase of chromite with space group Fd-3m. R-Factor (Profile R factor (Rp), Weighted R Factor (Rwp), Expected values (Rexp), Bragg R Factor (RB), Rf -Factor ), goodness fit factor(χ2), have been calculated. The lower values of profile parameters such as Rp, Rwp, RB,Rexp,Rf, χ2 indicated that the calculated diffraction pattern is in fair agreement with observed pattern. Some of the applications of Chromite have also been highlighted.

Abstract:Multiferroic Bi0.95Na0.05FeO3 was synthesized by solid state reaction method. XRD of the prepared sample was collected at room temperature in order to examine the crystal structure. The XRD pattern reveals that the sample has been synthesized well beside an impurity of Bi2O3 at angle 27.740. The Rietveld analyses of the obtained XRD pattern deduce the structure to be having a mixed phase with combination of Rhombohedral (R3c) and triclinic (P1) symmetries. The change in the structure may be attributed to the induced chemical pressure response with doping of Na. Moreover, the doping of Na has been found to suppress the growth of secondary phases.

Abstract:W-type hexaferrites having chemical composition SrCo2AgxFe16-xO27 (x = 0.0, 0.1, 0.2, 0.3) was synthesized by sol-gel technique. The structural, morphological and elemental distribution of synthesized nanohexaferrites was studied at temperature 12000 C calcinated for 4 hours. Analysis of structural, morphological and elemental composition of prepared samples was carried out by XRD (X-Ray diffraction), FESEM (Field Emission Scanning Electron Microscopy) and EDS (Energy Dispersive X-ray Spectroscopy). From the XRD analysis, the crystallite size is found to be in the range of 51-61 nm calculated by using Debye-Scherrer formula which means crystallite size increases with increase in silver concentration. FESEM analysis revealed that grains are hexagonal in shape. The EDS spectra of the prepared samples confirming the formation of pure nanohexaferrites and elemental composition infer that no elements except strontium, cobalt, silver, iron and oxygen are present in the synthesized samples. Key words:W-type hexaferrites, Sol-gel technique, structural and morphological study, elemental composition.

To enhance the tribological properties of Al, present work endeavors to provide a solution by developing oxide enriched recast layer with very smoothsurface through Electrical Discharge Machining (EDM). To achieve this objective,a fraction factorial table is developed by considering three levels of parameters of EDM (i) pulse on time (ii) peak current and (iii) spark on voltage.For each condition of fraction factorial tables, oxygen percentage (quantifying oxide layer formation) using Energy disperse x-ray spectroscopy (EDAX) and the surface roughness from atomic force microscope (AFM) is determined. Using these valuescontribution of parameters of EDM is determined by calculated least square values for three different cases (i) Case 1: considering only the percentage of oxygen, (ii) Case 2: considering only roughness values, and (iii) Case 3: considering 0.5 weight factor for Cases 1 and 2. From the determined contribution of each parameter, oxygen percentage and roughness values, the optimumoperating condition of EDM for achieving most favorable tribological condition is identified. Finally, to validate the finding tribological

Abstract: In this fast world we should need to know the blood group and type. So quick and perfect identification of blood sample is very important during the urgent situation. This future proposal is to change the physical work in medical laboratories for identifying the blood sample. Usually, the blood group analysis is made in the laboratories and there are three types of blood group analyzing methods, they are ABO forward typing, ABO reverse typing and Rhesus type testing. In the laboratories ABO type and Rhesus type testing techniques are mainly used. In the ABO testing method is used to identify the blood sample group. In the Rhesus testing method is used to identify the positive and negative of blood group. Even though it is easy to identify the blood group of single sample blood, but when handling the large number of blood samples, it might lead to wrong analysis. In order to solve this problem and reducing the manual involvement and to get better reliable result, we design the machine which will automatically identify the blood group based on the application of Infra Red (IR) light source. When the IR light is focused towards the blood sample, the light intensity is changed due to the blood darkness. It will be sensed by the IR light detector. The blood group and type can be identified by the intensity value of the light.

Abstract:Samples of CeO2-SiO2 nanocomposites were prepared using sol-gel method at different annealing temperature. The pure cubic fluorite structure of CeO2 nanocrystal has been achieved at ~ 300oC with a uniform distribution in SiO2 matrix. Structural parameters were confirmed by x-ray diffraction technique. The average nanocrystalline size has been calculated as 0.5, 1.5 and 2.5 nm using Debye-Scherrer formula for annealed samples. The prepared nanocomposite samples have capability to absorb and release oxygen without altering the fluorite structure of ceria. In the present study, we have analyzed that cerium oxide have ability to shift easily between reduced and oxidized states (Ce3+/Ce4+) and to accommodate variable levels of bulk and surface oxygen vacancies. The concentration of the oxygen vacancies decreases with the increase of annealing temperature and corresponding crystallite size. The surface area of annealed samples has also been estimated by Brunauer-Emmett-Teller (BET) equation. The photo catalytic activity was studied through the degradation of Rhodamine 6G in aqueous solution under visible light exposure. As prepared CeO2-SiO2 nanocomposite has the highest photo catalytic efficiency and then it is decreased with annealing temperature. Keywords: CeO2-SiO2, nanocomposites, Rhodamine 6G, annealing, dye-degradation etc.

Abstract: Plate like Cd(OH)2-CdO Nanocomposite has been synthesized by wet chemical technique in double distilled water. As-synthesized cadmium hydroxide/oxide particles transforms into pure oxide after annealing at 750°C for 2h. As obtained particles are having plate like surface morphology with 15 nm average diameter, while almost spherical as well as rod shaped nanostructures are formed after annealing. The FTIR spectroscopy provides the valuable information and identification of different chemical group/bonds present in the prepared samples. It is found that if we fixed the dopant concentration, then particle size, morphology and band gap energy of prepared nanopowder can be tailored by applying the annealing conditions. Comparative studies of absorption spectra and corresponding band gap energies have been done with thermal treatment. The shift of the optical absorption edge of prepared nanopowder towards lower energies increases its utilization in the visible region specially photocatalytic activity.

Abstract.Currently there is a great interest in II–VI semiconductor nanoparticles, particularly organically capped soluble particles of cadmium and selenide, for their ready to use application in devices. In this study, CdSe nanocrystalshave been synthesized by using starch as a capping agent through a chemical synthesis route at room temperature. Samples have been prepared varying quantity of precursor for Cadmium. It is observed that a turn on voltage is required for light emission and brightness increases exponentially with voltage. Turn on voltage is found to decrease as CdCl2 concentration is increased. The voltage-current curve represents ohmic nature for all EL cell. The EL spectra also show blue shift with increasing CdSe concentration. This tunability of band gap as well as light emission with size is very important in display applications.

Abstract. The study of 120 MeV Ni8+ ion beam radiation effects on commercial BJT devices 2N 3055 and 2N 6688 for various fluences are made. The devices have typical base width of 14.96 µm and 32.37 µm respectively. It is observed a non linear increase in reciprocal current gain after irradiation for fluence of 1×1010 ions/cm2 is due to the bulk displacement damage produced by Ni ion. The observed increase in the resistance is attributed to the increase of the base spreading-resistance of the transistor and the excess base current may depend on irradiation fluence. The carrier removal rate varies linearly with increase in ion fluence. Keywords—Transistor, Irradiation, Electrical Measurements, Junction Capacitance.

Abstract. Resistiveswitching devices have now become important candidates for non-volatile data memories. Resistive switching is a physical phenomenon where a dielectric suddenly changes its resistance under the action of strong electric field. The change in resistance is non-volatile so used in resistive random access memories which is a promising candidate for data storage applications. These devices were mainly fabricated by means of top down approach but because of the size limits, bottom up approach is used. The TiO2 nanoparticles are prepared using sol-gel method using Titanium isopropoxide as precursor. The particles prepared via sol-gel methodwere studied by UV-Vis spectroscopy and XRD. The band gap of the particles using Tauc’s equation is 3.5 eV having a tetragonal structure. From these TiO2 nanoparticles thin film is to be synthesized which is used for resistive switching applications.

Abstract: This paper presents a special method of communication for the speech impaired people and other patients using their hand gestures. A microcontroller based system has been developed for measuring fingers flexion to identify specific hand gestures using flex sensors. The system is made wearable and has been deployed on a glove. To measure the fingers flexion for a specific hand gesture five flex sensors are tailored for each finger on the glove. These flex sensors produce signals corresponding to different hand gestures and finger movements. Flex sensors simply change their resistance values according to the degree of bend angle made. They convert the change in bend to electrical resistance-the more the bend, the more is the resistance value. The system has been built around a widely used eight bit microcontroller ATMega328P that has a built-in 10-bit multiplexed channel Analog-to-Digital Converter for the signal conditioning purpose. The important issues while

A diamond radiation detector was fabricated using diamond grown on diamond substrate as a basic source material. The detector was tested byOptical Microscope, X-ray diffraction, Raman spectroscopy &(I-V) characteristics. Optical microscope confirms the surface morphology as well as grain boundaries of the diamond films. XRD confirms crystallinity and long range ordered of the film. Raman shows the good content of Sp3 bonds. The measured leakage current was very low ~2.3pA and ~40pA of substrate and grown diamond film and is in good agreement with the reported values by various research groups. The comparison study of silicon, germanium, gallium Arsenide and diamond confirms that diamond isradiation hard than other materials. It causes due to high atomic displacement energy i.e., energy required to displace a carbon atom from its lattice site.

* Corresponding author: [email protected] & [email protected] Abstract.Pyrochlore-structured oxides are known for its exceptionally high compositional diversity and structural flexibility facilitates them to use for various applications such as geometrically frustrated magnetism1, ferroelectricity2, photocatalysis3, photoluminescence4, magneto-optical5, solid oxide fuel cell6 etc. However, for the application point of view the main challenging task is the tuning and optimization of the materials properties. Herein, we presented the possibilities in the Ho2Ti2O7 polycrystalline compounds to be used for the magneto-optical and solid oxide fuel cell applications. It has been found that a partial substitution of the trivalent Fe3+ ion at the host tetravalent Ti4+ ion is not only creates the charge compensating oxygen vacancy but also modifies the optical band gap and sifting of the emission color coordinates in dark blue region from a critical composition. A systematic structural, magnetic and optical analysis reveals that above x= 0.1 critical compositions, a reduction in the oxygen coordination number (octahedral to tetrahedral) takes place and observed in the form of high to low spin crossover of the substituted Fe3+ ions. Our results provide a new route to tune the optical band gap and absorption coefficient in the visible-near IR region for different potential applications. References:

Abstract.The present work reports the effect of indium on structural, optical and gas sensing properties of chromium oxide. A wet chemical route was adopted for the synthesis of pure and indium doped chromium oxide nanoparticles. The synthesized samples were characterized using X-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy and UV-Visible spectroscopy for analysis of structural, morphological and optical properties. XRD studies confirmed the corundum structure of synthesized samples and indicate the decrease in crystallite size upon introduction of dopant in chromium oxide. Raman analysis revealed the shifting and broadening of peaks of doped sample as compared to pure one. Blue shift in band gap due to indium doping is also observed. Synthesized nanoparticles were applied as thick film onto an alumina substrate to act as gas sensor. Fabricated sensors were tested at various operating temperatures for detection of LPG and it was found that both the sensors exhibit optimum sensor response at 250°C. The investigation revealed that doped sample exhibits significantly high sensor response towards LPG as compared to pure.

Driven by this idea, PEO layer was introduced in TiO2 and TGr based PSC to determine the feasibility of achieving notably high fill factor useful for sundry applications. As-grown nanocomposites were analyzed using varied analytical tools to evaluate the effect of graphene inclusion on their morphology, optical and electrical properties. The UV–visible absorption spectra of the studied nanocomposites disclosed broad bandwidth and red-shift in the characteristic peak compared to pure TiO2based PSC, indicating band gap narrowing. Meanwhile, PL emission spectra exhibited a significant reduction in the electron–hole recombination. It is established that the present disclosure may contribute towards the development of novel ETL integrated high performing PEO based PSC.

Abstract. SrY1.7-XB0.3O4: xTb3+ nanocrystals were synthesized by sol-gel method and the solid obtained was fired at 700oC to 1000oC for 3 hours to increase the brightness and crystallinity. The sol-gel technique is based on hydrolysis of liquid precursors and formation of colloidal sols. The main advantage of sol-gel method is, molecular level homogeneity in solution stoichiometric control at lower temperature calcinations so this process has been exploited to produce nano particles. The nano crystals obtained through sol-gel method was characterized by using scanning electron microscopy (SEM), X-ray diffractions (XRD) and photoluminescence (PL) spectra. The average nanoparticles size of the synthesized nano phosphor was 50-80 nm. The photoluminescence (PL) spectra shows predominant green colour of the nanocrystals prepared under an UV source revealed green luminescence, that was attributed to transitions 5D4 → 7F5 of Tb3+ was located at 542 nm. Photoluminescence is at a maximum for the samples prepared with 5 mole % of Tb3+ and heated to 1000ºC. Keywords: Sol-gel synthesis, Nanocrystals, Photoluminescence

Abstract. A field experiment was carried to study the persistence and dislodging behaviour of ready-mix formulation Nativo 75G (trifloxystrobin 25% w/w + tebuconazole 50% w/w) residues in okra fruits. Fungicides formulation was sprayed thrice at 350 and 700 ml/ha at 7 days interval, starting from fruit initiation using Knapsack sprayer, in which, the tebuconazole dose was 175 and 350 g a.i./ha and trifloxystrobin 87.5 and 175.0 g a.i./ha, which were sprayed at single and double dose, respectively. Samples of okra fruits were collected periodically, i.e., 0 (just after 2 h), 1, 3, 5, 7, 10, 15, 20 and 25 days after last application. Residues of these fungicides were determined by gas chromatography (GC) and gas chromatography-tandem mass spectrometry (GC-MS/MS). The limits of quantification (LOQ) and detection (LOD) for both the fungicides were 0.01 and 0.003 mg kg-1, respectively. Dissipation of both the fungicide followed first order kinetics with half life (t 1/2) of 1.89-7.34 days. It was found that washing alone with tap water was effective in reduction of residues in both the pesticides. In case of tebuconazole, the percent residue reduction ranged from 63.63 to 75.16 at single and double dose. For trifloxystrobin, the maximum percent reduction was obtained on 0 (just after 2 h) day ranged from 74.15- 78.03 at single dose double dose.

Abstract: Optical materials exhibiting a large third-order optical nonlinearity are in great demands because of their functional applications in optical limiting, optical switching, optical data storage etc. A well-known single Z-scan technique is employed to determine third-order nonlinear optical properties of nonlinear optical materials. Z-scan is a simple experimental technique to measure intensity dependent nonlinear susceptibilities of third-order nonlinear optical materials. It was originally introduced by Sheik Bahae et.al. In this technique, the sample is translated in the z-direction along the axis of a focused Gaussian beam, and the far field intensity is measured as function of sample position. Consequently, increases and decreases in the maximum intensity incident on the sample produce wavefront distortions created by nonlinear optical effects. This is a simple and sensitive single beam technique to measure the sign and magnitude of both real and imaginary part of the third order nonlinear susceptibility χ(3) of nonlinear optical materials.

Organic nonlinear optical (NLO) active chromophore[1-(4-methylphenyl)-3-(4-N,N,dimethylaminophenyl)-2-propen-1-one (MPDMAPP)] doped Poly(methyl methacrylate) (PMMA) composite films were prepared using solution casting technique. Fluorescence study shows initial enhancement in the fluorescence emission intensity then attainsaturated value for higherdoping concentration. It is observed that the bright blue emission under wide band pass excitation at the wavelength of 270nm and green emission under green wide band pass excitation wavelength of 450nm. Here increase in the amorphous nature is due to the complete dissolution of dopant in the polymer matrix and it is excellent host matrix for dyes/chromophores. Positron annihilation lifetime (PALS) study shows fluoresce emission property is directly related to the available free volume size o-Ps lifetime within the composite.

Abstract.Integration of polyaniline (PANI) with reduced graphene oxide (rGO) resulting in PANI/rGO seems to be an effective way to eliminate the concern of cyclic stability attributed to the fragile back bone of polyaniline (PANI). Also, presence of aniline fibrils in the intervening layers of reduced graphene oxide enhances the conduction of the electrolytic ions in the resulting composite. The as-synthesized PANI/rGO composite shows an enhanced specific capacitance of 268 F g-1. All these results project PANI/rGO as an attractive electrode material for supercapacitor application.

Abstract: The oxidative polymerization process has been used to prepare composites of Polyaniline/iron oxide (PANI/Fe2O3). For synthesis of these composites, Polyaniline using different amounts (10, 20, 30, 40, 50 wt %) of the Fe2O3 with oxidant ammonium persulphate have been used. Temperature dependent dc conductivity measurement is done in temperature range up to 1200C using Mott’s model. Mott’s VRH mechanism is a phonon assisted quantum-mechanical transport phenomena in which the thermodynamic procedures explains the movement of charge carriers to a nearby isolated state of different energy, while the quantum mechanical tunneling describes the movement of a charge carriers to a farther off localized state of similar energy. Mott’s model explains the conduction by hopping process in disordered semiconducting systems and match well with the experimental data. DC electrical conductivity increases with increase in temperature (figure 2) due to increase in free charges with increase in temperature Keywords: Polyaniline, DC Conductivity

Abstract.Considerable as well as thriving demand and challenges of transportation industry such as cost cutting measures, new environmental conservation regulations and the impressive growth in terms of transport volumes open windows for ingenious joining technologies for new materials that possess high fracture toughness, better environmental resistance characteristics and recyclability. But materials and their conversion into products play the major role in the applicability. Escalation of thermoplastic usage in large structural components also faces similar ambiguity for joining multi-material structures. Friction assisted riveting technology called ‘Friction riveting’ is the cogent joining technology in tackling these challenges. Processing of materials is the key research area where the required outcomes are expected in terms of performance, strength and durability. Typical studies are discussed in this review article. A study on the influences and impacts of process parameters such as rotational speed is presented in this paper which provides a new gateway for the further betterments.

We have investigated the interaction of nucleobases – Adenine (A), Guanine (G), Cytosine (C), Thymine (T) and Uracil (U) with ultrathin monoclinic VO2 nanowire by first principles calculation.The interaction between the bio-molecules and NW is observed due to physiosorption.We have observed the semiconducting behavior for nucleobase adsorbed VO2-NW, except cytosine. However, the change in band gap is observed, which could be due to the movement of charge. The hybridization bond between the molecules and NW is confirmed from their orbital contributions at valence band. Our study presents a significant idea about how the nucleobases can be affected by the interaction with VO2 nanowire.

Abstract: Polymer/ZnO nanocomposites have shown a great scientific interest in linear optical properties due to a wide range of applications in the optical devices. The nanocomposites were prepared by mixing the ZnO nanoparticles with Polystyrene (PS) as polymer matrix. Different concentrations of ZnO nanoparticles were used as fillers in the nanocomposites. In the presented work, the PS/ZnO nanocomposite foils have been prepared by using the casting method. The as prepared nanocomposite foils were characterized by using XRD (X-ray diffraction) as well as UV-Visible (UV-Vis) spectroscopy. The transmittance and absorbance of these foils were evaluated from UV-Vis spectra. Transmittance spectra have shown low transmittance in UV region which is inversely related to the concentration of ZnO nanoparticles in these nanocomposite. These nanocomposite foils were found to be highly transparent throughout the visible region and absorb UV light. The observation highlights the possible prospects of these foils in UV shielding applications. Keywords: Nanoparticles, PS/ZnO, Nanocomposites, Polymer matrix, UV protection etc.

Abstract.Being thermo-polymer, polypropylene is widely used in various applications such as packaging, stationery, plastic parts, reusable containers, laboratory equipment, loud speakers, automotive components, etc. But while conventional drill bits are used irregular holes are resulted and rough edges lead to cracking. Larger the hole, slower the drill speed since high speeds can melt the plastic. The drill speed should keep very low during exit or else chipping of the bottom surface would occur. This drilling process could overcome all the limitations of conventional drilling. It employs the heat produced from the frictional contact between the rotating flow drill and the sheet work material. In thermal drilling, large deformation of workpiece as well as both the tool and work piece temperatures is high. Hence, modeling and simulation is an essential tool to predict the material flow, and temperature distribution which are difficult to measure experimentally during thermal drilling. The objective of this work is to numerically analyze the quality of bush formation in the thin sheet of polypropylene and to forecast the strain, stress and temperature in the work piece.

Abstract: ZnO nanoparticles have drawn a widespread attention recently due to their novel properties which contribute to various applications especially in gas sensing and optoelectronic devices. This paper presents a surfactant-assisted complex wet chemical method for the controlled preparation of Zinc Oxide (ZnO) nanoparticles using zinc acetate as starting material. Here, the spherical ZnO nanoparticles with average size of less than 50 nm were successfully synthesized and their optical properties were analysed. In order to maximize its efficiency, surface modification with surfactants is vital as ZnO nanoparticles easily agglomerate. The effects of the surfactant on the average particle size and morphology of the ZnO nanoparticles were investigated using X-ray diffraction. Well dispersed ZnO nanoparticles with a uniform size distribution were obtained usingPoly Vinyl Alcohol (PVA)as a surfactant. The addition of surfactants controlled the particle size and reduced the formation of agglomerates and at the same time helped to produce more homogenous and uniformly dispersed particles. Keywords: zinc oxide, nanoparticles, surfactants, PVA and microwave synthesis.

The SEM image clarify the porous nature of hybrid composites was governed by out-bust of tapped water and gases by thermal decomposition of metal precursors. The TEM image have manifested the uniform crystalline nature of LaMnO3 with inter layer spacing 0.39 nm. Spectral analysis was studied by FT-IR, which indicated the stretching modes of Mn-O-Mn are associated with octahedron MnO6 vibrations. Interestingly, the cyclic voltammetry (CV) curves are completely acknowledged with the pseudocapacitive nature in presence of LaMnO3 and resultant capacitance values are vividly increased by addition of graphene. The calculated highest specific capacitance value of hybrid composite and LaMnO3 are 1032 and 586 F g-1, respectively as well as excellent rate capability was observed after addition of graphene with perovskite structure.

However, it is a key challenge to fabricate the composite based devices over flexible substrates of performance similar to the rigid devices. In this paper, we report the fabrication of P3HT:graphene nanocomposite based photodiodes with the architecture of ITO/P3HT:graphene/Al on Indium tin oxide (ITO) coated glass substrate as well as on the ITO coated flexible polyethylene terephthalate (PET) substrate. The measured current-voltage (I-V) characteristics of the fabricated devices on both the PET and glass substrate under dark condition have found to be similar to the Schottky diode. Various essential diode parameters, such as, barrier height, ideality factor, series resistance have been estimated. The flexible device show relatively large photocurrent and small dark current over the measurement range compare to the device over hard substrate that might results from the better interface properties. This indicates the enormous potential of flexible devices for many imperative future applications.

Abstract.The research paper describes the in situ synthesis of silver nanoparticles (AgNPs) using Bombyxmorisilk sericin (SS). The formation of silver nanoparticles in the SS solution was confirmed by using UV-Visible spectroscopy (UV-Vis), X-ray diffraction measurements (XRD), transmission electron microscopy (TEM) and dynamic light scattering (DLS) experiments. The UV-Vis absorption spectra of the SS-AgNPs colloids showed surface Plasmon resonance in the wavelength range of 418-425 nm confirms the silver nanoparticles formation. The XRD scan revealed the nanocrystalline phase of silver with FCC crystal structure. The TEM images shown the formed silver nanoparticles are spherical in shape with smooth edges and diameter of the particles around 5-20 nm. The DLS results indicated the average size of the nanoparticles is slightly bigger in size compared with TEM values. All the results support the sericin as a prominent bio-template for reduction of silver ions to silver neutral atoms.

Abstract.Carbon supported MoS2 nanocomposite has been extensively used as a catalyst for hydrogen evolution reaction as well as hydrotreating process. However, their synthesis method majorly involves post-synthetic installation of MoS2 nanoparticles or sheets on the carbon support via hydrothermal reaction or high-temperature sulfidation of molybdenum oxide precursors. Herein, highly dispersed low-dimensional MoSx nanoparticles (NPs) with a particle size as small as 2.4±0.6 nm were successfully synthesized by purging H2S into the polyoxomolybdate solution (A3[PMo12O40]; A+ = H+, NH4

+) in the presence of different capping agents (SDS and PVP). Furthermore, these MoSx nanoparticles was found to exhibit excitation-wavelength-dependent photoluminescence behavior.Upon annealing of capping agent stabilized MoSx nanoparticles at 450 °C for 6 h in Ar atmosphere, in-situ carbonization of capping agents (SDS/PVP) has occurred which led to the formation of amorphous carbon supported MoS2 nanocomposite. The formation of amorphous carbon was verified using FT-Raman spectroscopy study whereas the presence of MoS2 was established with the help of XRD, TEM, SAED, XPS, and FT-Raman spectroscopy techniques. The small size of the precursor MoSx nanoparticles was presumed to be the driving force for the formation of highly disperse few layers of MoS2 wherein surface ligands dehydrogenated and polymerized to form the amorphous carbon supports for the as-formed few layers of MoS2, hence control their final size of the particles.Synthetic ease of the as prepared carbon supported MoS2 nanocomposite may encourage the effective application of this materials for heterogeneous catalysis and electrochemical applications.

These materials exhibits vide range of physical properties from paramagnetic, ferromagnetic and antiferromagnetic to Mott insulator, half metallicity and large magnetoresistance. Double perovskite structure is basically three dimensional network of corner shearing octahedral with general formula A2BB’O6, where the octhaderaBO6 and B’O6are arranged alternately. The interaction of these transition elements in double perovskite structure is vital, different suitable combination of elements at B and B’ site can exhibit novel phenomenon. In this study we have synthesized nano-sized Pr2CoMnO6 compound. We have investigated structural and temperature dependent magnetic behavior. Structural study shows that the material crystalized in orthorhombic crystal structure with Pbnm phase group. Magnetic study shows that Pr2CoMnO6 exhibits paramagnetic to ferromagnetic phase transition around TC~ 173K. Careful analysis of zero field cooled (ZFC) data shows a Griffith type phase appears near TC. Isothermal magnetization data at 2 K confirm ferromagnetic phase with large hysteresis present in this material.

Abstract. Silver nanoparticles embedded Polyvinyl alcohol (PVA) nanocomposites samples were prepared by in‒situ chemical reduction of silver nitrate (AgNO3) in an aqueous solution of PVA. The prepared nanocomposite films were exposed to ultraviolet (UV) radiations for different times at room temperature. The UV irradiation induced modification has been studied through optical spectroscopy and electrical measurements. The appearance of Surface Plasmon Resonance (SPR) band at 425 nm in the UV-Visible absorption spectra of PVA/Ag nanocomposite confirms the presence of the silver nanoparticles in PVA matrix. The optical energy gap values were found to reduce from 4.92 eV in pure PVA to 4.61 eV for PVA/Ag nanocomposites without UV irradiation, which further reduces to 4.40 eV after UV irradiation for 240 minutes. Such a reduction in optical energy gap may be linked to the increased conjugation in PVA matrix as an effect of embedding of silver nanoparticles. The value of conductivity increases from 4.16 x 10‒9 S/m for pure PVA to 3.64 x 10‒8 S/m for PVA/Ag nanocomposites which further enhances with the increase of UV exposure. Keywords: Ag nanoparticles, UV irradiation, Optical Energy Gap, I‒V Characteristic.

Abstract. In this research , I have introduce the concept of open-collector gates. These are gates with internal organizations that allow them to participate in a wired-AND configuration, similar to the DTL gates in. The pull-up path, namely the R3 resistor, Q4 transistor, and the diode of the output stage of Figure 2, is eliminated in an open-collector gate. Thus, an open-collector gate only has the ability to pull down its output node. We need a resistor external to the gate. This pulls up the wired-AND output if none of the attached gates have an input combination that provides a pull-down path to ground. It has also introduced in this research the concept of tri-state gates. These are gates with three possible interpretations of their outputs: logic 0, logic 1, and no connection. The latter is called the high-impedance state and is -denoted by the "value" Z. Key Words: open-collector gates, organizations, pull-down path, high-impedance.

Abstract. The present work is concerned with the problem of micropolar magneto-thermoelastic interactions in a functionally graded isotropic medium in the context of Lord-Shulman (L-S) theory. The governing equations of generalized thermoelasticity for a functionally graded material under the influence of a magnetic field are established. Material properties are assumed to be graded in x-direction. A normal mode scheme is presented to obtain numerical solutions with high accuracy. The system of differential equations is solved numerically for a hypothetical material and some plots for temperature, displacement, force stress distribution and couple stress are presented graphically. The effect of non-homogeneity is also seen for different values of the non-homogeneity parameter and the properties of the material depend largely on the inclination of applied source.

Abstract. The present paper is aimed to model and study the characteristics of various reflected waves in a homogeneous fiber reinforced anisotropic diffusive magneto-thermoelastic solid within the context of dual phase lag theory of generalized thermoelasticity. Amplitude ratios and energy ratios of various reflected waves are presented when an elastic wave is made incident obliquely at the plane boundary of a fiber reinforced magneto-thermoelastic solid half-space with diffusion. It has been verified that there is no dissipation of energy at the boundary surface during reflection. Numerical examples calculate the amplitude ratios to evince the effects of various parameters embedded in the considered system and the results obtained are depicted graphically.

a) Corresponding author: [email protected] Abstract. The variation of physical properties of nanomaterials have been a matter of great debate in the recent decades. Different researchers have reported drastic change in the physical properties of metals at their nano scale with their different shapes. In the present work, we have computed the theoretical values of Young’s modulus and Bulk Modulus of ofAluminium (Al), Nickel (Ni) and Silver (Ag) having their size less than 30 nm with different shapes (i.e. for spherical and non-spherical). For computation we have consider the fundamental relation of cohesive energy with melting point. Variation in elastic constants has been interpreted on the basis of the presence of number of surface atoms due to the change in surface to volume ratio of metals at the nano level. The physical properties change in different manner due to their shape factor. In present study it is found that there is a drastic change in the physical properties of nanomaterials below 20 nanometers. This study also shows that the shape of nanoparticles plays an important role to affect their physical properties.

Corresponding author: [email protected] Abstract. Cyclic codes are an interesting type of linear codes and have wide applications in communication and storage system due to their efficient encoding and decoding algorithms. A cyclic code can be study completely by studying its minimal cyclic codes. Let Fq be a finite field of order q, where q is of the form 2nk+1 and m be a positive integer co-prime to q. Let p, q, l be distinct odd primes s.t. q is a primitive root modulo pm as well as modulo l. In this paper, we obtained the explicit expressions for cyclotomic – cosets of the minimal cyclic codes of length 2npml. An example is also given to justify the significance of the expressions obtained for calculating cyclotomic – cosets.

Abstract.The article is devoted to modeling of bus passenger carriers. Such companies are strictly regulated by regulatory authorities. Consequently, the financial performance of passenger carriers can change dramatically via decisions of the regulator. Because of this, the adaptation of carriers to the requirements of the regulator is very important question. In this paper, quite natural assumptions about the relationship between the main quantitative indicators of passenger carriers were formulated. This allowed us to derive a differential equation for the dynamics of the carrieres profit under the conditions of constant external economic environment. For this equation, asymptotic estimates of the solutions and an estimate of the adaptation time carrier were obtained.

Abstract.In the current work, an approach using intelligent agents is proposed, which at each step simulates the choice of public transport by the passenger. Several algorithms of agent behavior will be considered, one of which is based on reinforcement training. The algorithms take into account the history of the agent's previous trips and the quality of transport services. An iterative approach is used, so the quality and satisfaction of transport services is determined at each step. The average satisfaction rating for a certain set of passengers is calculated.

Abstract. The proposed research work has been taken up to understand deformation characteristics of compacted and sintered cylindrical preform considering the effect of strain rates by introducing different lubricating conditions at the ends of the preform. The radius of curvature of the bulged preform was measured during the experiments and found to be confirmed with the calculated one. It is assumed that the curvature of the bulge followed the form of a circular arc and accordingly calculated. The experiments were conducted for three aspects ratios. The frictional forces developed between platens/forming tools are impartment considerations in sintered-preform working process and in addition to this, the variation of strain rates have also been studied. Between various bulge parameters like strain, geometrical shape and stress ratios, the mathematical relationships have been developed and found in good correlation with experimental data. It would be helpful for those who are working in the field of mathematical modeling of sintered metal powder products. The results so obtained are discussed critically and will be presented graphically. Key word: - Geometrical shape factor(GSF), Sintered preform, Strain rate, Friction

Abstract: Most of the systems we use in our daily life are software based. In order to successful use of system it is necessary that system should be reliable. In this paper, the enhancement in software reliability is obtained by a comparative study of the estimated results of two different predefined models namely NHPP model (non homogeneous Poisson process model) and Musa model by considering two types of faults long lasting (permanent) and temporary (transient) faults. Both faults are treated as independently and removed separately. Permanent fault follows exponential distribution and transient fault follows the Weibull distribution. For the agile software development, the comparison of two yields an effective and reliable model.

Abstract. The layered Zn-Y hydroxides containing succinate, adipate, sebacate and benzoate as inter layer anions were synthesized with the objective of integrating organic molecules with inorganic structures to produce hybrid materials where in the advantages of both the components can be retained in one material. The structures were characterized by various analytical techniques such as PXRD, FTIR and TGA techniques. The optical characteristics of these samples were evaluated using UV-visible and PL spectroscopic techniques. While the monolayer arrangement within the interlayer could be conceived for succinate, adipate and sebacate from their PXRD patterns and FTIR spectra, presence of tilted bilayers of benzoate in the interlayer between Zn-Y hydroxides was identified. The interlayer separation of the intercalated samples varied linearly with the number of -CH2 groups, n, in the aliphatic chain of dicarboxylates. Intercalated samples showed higher thermal stability as compared to acetate intercalated system. In addition to the π-π* transitions from carboxylates, surface defects of Zn-Y hydroxide system was observed as luminescence emission in the visible region of the spectrum.

Abstract. In the present study, we have tried to characterize the inclusion complex of Hexaflumuron (HFM) with β-cyclodextrin (β-CD) using 1H & 19F NMR experiments. HFM is a pesticide (anti-termite) belonging to benzoylphenylurea family that contains three classes of fluorine. Its’ very low aqueous solubility can lead to facile accumulation in water or soil causing rapid poisoning of the environment. Therefore, elimination of HFM requires scavenging agents such as β-CD that can encapsulate HFM resulting in better aqueous solubility. A significant change in 19F and 1H NMR chemical shift, 1H & 19F longitudinal (T1) and 19F transverse relaxation (T2) time was observed for HFM in the presence of CD that confirms HFM-CD association. Jobs Plot demonstrated that β-CD was found to form 2:1 inclusion complex with HFM. Association constant was determined from chemical shift titration method using modified Benesi -Hildebrand plot. The present study for the first time provides an insight in understanding formulation of HFM in β-CD enhancing the solubility giving rise to a possible soil remediation method.

Abstract . Cotton (Gossypium spp.) is an economically important crop and its contribution to the global fiber industry is continuously growing. Presently, cotton is under cultivation in more than 70 countries globally with India ranking first in acreage [1]. Drought is one of the major destabilizing factors in its productivity. It effects the plant genetic expression and consequently the product quality [2]. Substantial efforts are required to improve cotton production in drought prone areas for improving production quality and quantity. The yield improvement in cotton crop plants can be achieved by incorporating stable and ideal plant traits associated with drought tolerance in the plant system. The abiotic stress like drought alters various metabolic processes in plants. Thus, the study of alterations in primary and secondary metabolites will not only provide an insight on molecular mechanisms but also will help in identification of drought resistant species more effectively. In this study, we have proposed NMR spectroscopy based metabolomics of stem of gossypium viz. G. hirusutum and G. herbaceum for identification of drought stress responsive species and the underlying mechanisms. A total of forty-five metabolites were identified viz. leucine, isoleucine, valine, glucose, sucrose, fructose, xylulose, maltose, proline, asparagine, citrate, ornithine, citrulline, GABA, glycinebetaine etc. Non-overlapping signals arising due to resonances of alanine, acetate, glycinebetaine, glucose and sucrose were quantitated with respect to TSP. Univariate statistical differences between G. herbaceum and G. hirusutum controls and drought stressed plants were analyzed for statistical significance (p<0.05) using Kruskal-Wallis test followed by Mann-Whitney U test for individual comparisons. The variation in above five metabolites in control and stressed cotton plants have indicated that metabolic processes get altered significantly in stressed conditions. References: [1] S. N.

Abstract. The Newman superposition-model has been used to investigate the substitution of Mn2+ for Zn2+ sites in ZnBr2(OPPh3)2 single crystals. The calculated values of the zero-field splitting parameters (ZFS) at room temperature fit the experimental one taken from the literature. The satisfactory reproduction of experimental values of ZFS parameters indicate that Mn2+ substitute in place of Zn2+ in the lattice and does not cause appreciable local distortion in the single crystals. The calculations are made with the assumption that the total field experienced at an ion in a crystal is due to nearby neighbouring ions, using power law exponent t2 = 7±1 and t4 = 10±1 the reference distance R = 0.22 nm for Mn2+ surrounded by bromine and oxygen. The superposition model analysis shows that for large values of b2

Abstract: Three multifunctional dipodal ligands viz; MPC, DAN2NAP and DANPYRO with the variations in central units and spacers containing catechol, 2-naphthol and pyrogallol as binding moieties respectively, have been developed. Theoretical studies of the ligands werecarried out by DFT method for the thermodynamic behavior, stability and reactivity prediction. The calculations were carried out in gas phase. The Density Functional Theory (DFT) with B3LYP functional associated to 6-311G (d,p) basis was used to perform the calculations. The thermodynamic properties such as enthalpy change (∆H), entropy (∆S) and free energy (∆G) were computed and the formation constants (Kf) were obtained from ΔG using a standard equation of Kf = exp(-Δr G/RT). The global indices of reactivity and the electronic properties of the ligands are described and determined by TD-DFT calculations using the same level of theory. MPC ligand with a longer spacer shows higherstability than other two ligands as indicated by a minimum strain energy (E = -1563.70) and less ΔG value (ΔG = -350.74). Frontier molecular calculation shows less band gap in DAN2NAP ligand. Keywords:Dipodal Ligand, DFT, Thermodynamic and Reactivity

The powder of Cuminumcyminum (Zeera) was investigated by Weight loss method, Potentiodynamic polarization and Electrochemical impedance spectroscopy (EIS)techniques on mild steel in 5.0 M hydrochloric acid medium. The percentage corrosion inhibition efficiency was found to increase with increase in concentration of Cuminumcyminumfrom 0.1 to 4.0 g/l and STPP from 100 to 300 ppm. Polarization measurement indicates that Cuminumcyminum acts as a mixed-type corrosion inhibitor. Percentage corrosion inhibition efficiency shown by Cuminumcyminum (4.0 g/l) and 300 ppm sodium tripolyphosphate (STPP) in 5.0 M HCl solution for mild steel was 85.0 % and 80.0 % respectively. It is observed that green corrosion inhibitors are far better than chemical corrosion inhibitors as addition of chemicals to the system leads to environment pollution as well as other problems like sludge formation scaling, fouling etc. Keywords: Acid corrosion, EIS, SEM, Corrosion inhibition, Mild Steel, STPP, Cuminum cyminum.

Abstract.Triplex is short time vital structures of nucleic acidsformed in many biological processes. The study of triplex structure not only limited to explanation of vital processes but also extended up to its usefulness as biotechnical tools, gene-engineering and bio-nanotechnology. Such enormous application of triplex structure demands TFO(triplex-forming oligonucleotides) with greater binding affinity and stability. In this respect modification in oligonucleotides as LNA(Locked Nucleic Acids), locked sugar in RNA like C3’-endo conformation as RNA form more stable triplex but its application limited in biological environment due to blood clearance. Thus, here in this study, a 15-mer triplex was designed and molecular dynamics of 50ns run to see stability during simulation and QM/MM was done for triplet wise decomposition energy analysis with PM3 and PM6 methodology. The result of study exhibits that LNA triplets play essential role in the form of triplet and binds with greater affinity.

Abstract. Micellization behavior of anionic surfactant sodium caprylate (SCAP) and cationic surfactant cetyl pyridinium chloride (CPC) in presence of polymers (polyvinyl pyrrolidone, Tween-20, Tween-40, Tween-60 and Tween-80) in aqueous solutions has been investigated using conductivity and viscosity measurements at 298.15 K. The critical micellar concentration (CMC), critical aggregation concentration (CAC) and polymer saturation point (PSP) for both the surfactants have been determined in water as well as in aqueous polymer solutions having different concentrations. The CAC values for both the surfactants were found to decrease slightly with increase in polymer concentration whereas PSP values remained almost constant. The degree of ionization () and standard free energy of transfer (∆Go

t) have been estimated. ∆Got values were found to decrease with increase in polymer

concentration. The relative viscosity, ηr, for the above systems has also been determined at 298.15 K in various polymer solutions. The maximum value of ηI/ηI,max (ηI is the interaction viscosity) as a function of R (ratio of concentration of surfactant to that of polymer), shifts towards the lower values of R with the increase in polymer concentration. The results have been discussed in terms of various interactions occurring in these systems. Keywords: Sodium caprylate; Cetyl pyridinium chloride; Polyvinyl pyrrolidone; Tweens; Micellization.

Abstract.In this study pure polyvinyl alcohol (PVA) and polyvinyl alcohol/Bosewellic acid (PVA/BA) films were prepared by solvent casting method. The thermal behavior of pure PVA and its composites has been studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). From thermogravimetric study it was cleared that the decomposition behavior of PVA changed with addition of boswellic acid (BA). The DSC studies revealed that the increase in the composition of boswellic acid in PVA, slight decrease in the glass transition temperature (Tg), melting temperature (Tm) and decomposition temperature (Td) was observed. Kinetic parmeters including activation energy of degradation has been calculated using Coat and Redfern method. From the XRD it is clear that percent of crystallinity decreases with increase in the percent of boswellic acid (BA) in PVA could be due to development of semicrystallinity in PVA structure. Keywords: PVA, Boswellic acid (BA), DSC, TGA, XRD, kinetic parameters.

*Corresponding author: [email protected] Abstract In this article, new chitosan/4-Hydropxycoumarin (CHC) composite films were prepared and characterized. In the present work, the influence of 4-Hydroxycoumarine on chitosan (CH) structures and their surface morphology, thermal behaviour and hydrophilic nature of the PVA films were studied. The experimental studies showed that surface morphology become uniform and surface roughness has descending order as the concentration of 4-HC in the chtiosan (CH) film. The thermal properties of the CH films slightly increased with incorporation of different concentration of 4-Hydroxycoumarine (4-HC). This suggests that there is compatibility among components indicating the appreciable intermolecular interaction among the CH and 4-HC which is confirmed by the FTIR study. In addition presence of single glass transition temperature in all CHC composite films suggests the miscibility among the components. The result of water contact angle study showed that contact angle deceased with addition of 4-HC onto the CH indicating the composite films were hydrophilic in nature and affinity towards water increased in CHC composite films when compared to pure CH. The use of biopolymers, especially natural polymers like chitosan and polysaccharides became highly perishable in food packaging industry. This has enabled the use of biopolymers due to their biodegradability, cost effective, ease of preparation, good mechanical and barrier properties. It can be expected that, the best properties of CHC composite films were recorded in the study may play a vital role in food packaging and biomedical applications.

* Corresponding author: [email protected] Abstract The present study aims to prepare 4-hydroxycoumarine doped poly (vinyl alcohol) blend films using casting technique. The mechanical, thermal, Crystallinity, surface morphology, hydrophobic/hydrophilic and spectroscopic investigations were carried out by using Universal testing machine (UTM), Thermogravimetric analysis (TGA), Atomic force microscopy (AFM), Water contact angle and Fourier transform infrared spectroscopy (FTIR) respectively. The results of UTM showed that, mechanical properties of the PVA films did not influenced with incorporation of different concentration of 4-HC. This suggests that lower compatibility among the appreciable intermolecular interaction among the PVA and 4-HC indicated by the FTIR study. In addition noticeable variations were observed in some functional properties including surface morphology, thermal properties and water contact angle measurement. The results of AFM study showed that the surface morphology become uniform and surface roughness increased with increase in the concentration of 4-HC in the PVA film. The slight rise in the thermal stability of the PVA films were observed with incorporation of 4-HC. The result of X-ray diffraction study confirmed that composite films were amorphous in nature. Finally, water contact measurement confirmed the all composite films were hydrophilic in nature. The present study concludes that study can be extended to the application level and the prepared composite films may play a vital role in food packaging and biomedical applications.

Abstract. When a dead body is recovered from the water, the forensic scientist has to ascertain not only the exact cause of death (anti-mortem or post-mortem drowning) but also the accurate place of drowning. The diatom test is conducted to ascertain the presence or absence of diatoms in the tissue/bone marrowrecovered from the drowned victims during postmortem. The results proves to be very promising and widely used as a marker to solve the cases of suspected drowning. Therefore, in the present study, an attempt has been made to study the diatom profile of Bhakra canal near Narwana, Haryana, India. The diatoms were identified by using both light and scanning electron microscope. A total of 13 genera and 24 species of diatoms were observed andNavicula, Nitzschia and Synedra were found to be commonly occurring diatomspecies, Cymbella, Cocconeis, and Aulacoseira were identified as seasonally occurring diatoms, while Rhoicosphenia, and Achnanthes were site-specific diatoms. In this way the presence of site-specific diatoms helps in pinpointing the putative site of drowning, which goes a long way in helping the forensic scientists to answers the questions related to drowning.

Department of Physics, Guru Nanak Dev University, Amritsar-143005, India 1Corresponding Author: [email protected]

Abstract.Groundwater quality is at a degrading rate with the enhancement of anthropogenic as well as some of the natural causes in some parts of the Punjab state, India. Many workers have carried out the monitoring of the water quality. In the present investigations the quality check is been proceeded in some villages of Tehsil Patti in Taran Taran district of Punjab State. This region is supposed to be highly indulged in cultivation and use of various fertilizers. We have collected twenty samples at different depths from groundwater sources, most of which are from borewells and are analysed for their physical and chemical suitability for drinking purposes. More than half of the samples have exceeded the recommended guideline values for TDS (500ppm) and Uranium (30µg/l). The minimum and maximum values for uranium in this region are observed at 0.89µg/l and 120.05µg/l respectively. Maximum TDS observed in this region is upto 1365ppm which is quite higher than the recommended value. As most of the samples collected are used for drinking purposes, the higher values of uranium and TDS may lead to health risks with the long term usage of the groundwater in this region. We have also measured the pH, ORP, hardness, calcium, magnesium, chloride, alkalinity, carbonate and bicarbonates in the samples. The results of these parameters will be discussed in the paper. It is suggested to make out plans for monitoring the water quality time to time and establishment of various effective methods for utilising groundwater resources.

Department of Applied Chemistry, Laxminarayan Institute of Technology, R.T.M.Nagpur University, Nagpur – 440010.

Abstract. Risks to ecosystem vary significantly depending upon the nature and extend of exposure to hazardous chemicals. Stringent rules laid by various Environment protection agencies distinguish risks on the basis the utility and runaway hazards. Benzoic acid and 4-Nitro benzoic acid are widely used in food preservatives, cosmetic, and pharmaceutical industries. Anthropogenic releases of such chemicals into the environment are predominantly into water and soil. In the present study, advance oxidative processes namely UV/H2O2 and dark and UV Fenton, solar Fenton were investigated for the degradation of benzoic acid and 4-Nitrobenzoic acid (4-NBA) in lab-scale photoreactor. The process being highly dependent on experimental parameters, degradation studies were carried out at different [H2O2]/[BA], [H2O2]/[4-NBA] molar ratios and pH values in order to establish optimum experimental conditions for the processes studied. The obtained results show that Fenton process works effectively at acidic conditions and has much higher oxidation rate as compared with the UV/H2O2 process in case of BA, whereas for 4NBA Fenton like process works more effective. Oxidative degradation of contaminants by solar Fenton process was having highest degradation rate for Fenton process than for Fenton like process in both BA and 4-NBA. The optimum degradation conditions for 4-NBA by the photo Fenton like process are at pH 3.5, [Fe3+] at 4 ppm with molar ratio of 1.5 for [H2O2]/[4-NBA]. The optimum degradation conditions for BA by the photo Fenton process are at pH 3.5, [Fe2+] at 7 ppm with molar ratio of 5.0 for [H2O2]/[4-BA].

Abstract.The kinetic outcome shows unit order for heptavalent manganese (HVMG) and fractional orders for substrate cefadroxil (CFR) and H+ ions. Five oxidation products of CFR were identified by mass spectral analysis. The effect of different parameters on the oxidation kinetics of CFR by HVMG was studied thoroughly. Permanganic acid is found to be an active dominant and strong oxidizing species. The pH dependent second order rate constants were determined and found higher in acidic medium. Rate constants and activation parameters were evaluated from the influence of variation in temperature on the rate of reaction. The plausible mechanism and derived rate law are consistent with the experimental results. There is a formation of intermediate complex between CFR and HVMG which subsequently degrades into various degraded products.

Abstract.Ruthenium doped titanium dioxide nanoparticles (RDTDONPs) were prepared by liquid impregnation method to use as a photocatalyst. These particles were characterized by different methods and used for the photocatalytic degradation of drug Linezolid (LNZ) under UV illumination at 254 nm for pH ranging from 4.0 to 8.0. Five UV degraded products of LNZ were identified by High Resolution Mass Spectrophotometry (HR-MS). The average crystallite size of photocatalysts were found to be 17.08 nm, 16.71 nm, 15.65 nm and 14.36 nm for undoped titanium dioxide nanoparticles (UTDONPs), 0.2%, 0.4% and 0.8% (mole ratio) RDTDONPs respectively using Scherrer equation. This shows that the photocatalytic activity in 0.8% (mole ratio) RDTDONPs is higher due to increase in surface activity. The observed rate constants (kobs) were found to be increased with increase in the dosage of the photocatalyst. The values of kobs were found to be increased with decrease in pH. Kinetic data reveals that there is initial increase in the values of kobs with increase in the [LNZ]. Photo-degradation electron hole pair mechanism is proposed in agreement with the experimental results. Kinetic experiments show that the values of kobs increases with increase in light intensity.

Abstract. India is a highly populated country having about 1250 million people. It has a huge demand of power which is very tough to be fulfilled by the existed energy sources. The main sources of energy are coal, petrol, fossil fuels. But the production of power from these sources generate a huge amount of pollution in our atmosphere. Due to the environment pollution, most of the people suffer breathing problem and other various kinds of health problems. Therefore, we need to move towards natural sources of renewable energy e.g. solar energy, wind energy and hydro power to cater the needs of our society. Many of the countries are moving to these natural resources of energy. The solar power is a very clean and natural resource of energy. It is non-contaminated and vast source of power. The solar energy does not produce Co2 and other emissions. Therefore, solar energy is extremely safe and in abundance. India is situated at such a nice geographical location that it gets tremendous quantity of Sun light for the whole year. In this state of affairs, the Government of India has taken a note to concentrate on methods to utilise solar energy to generate power and develop many solar cities and solar parks.

Abstract. The awareness of environmental problems has forced governments, local authorities and utilities for management to search for new alternative process or solutions for future wastewater management strategies. To increase the efficiency of biological wastewater treatment processes, a variety of engineering solutions have been developed in recent years. Adequate treatment is necessary to prevent contamination of receiving waters to a degree which might interfere with their best or intended use, whether it be for water supply, recreation, or any other required purpose. The sewage treatment technologies have proven to be expensive, complex and are failing to cater to the total wastewater generated. The untreated/partially treated wastewater makes its way to the water body causing immense degradation of the ecosystem and the environmental health. Some effective, advanced treatment technologies take high construction /maintenance costs, and high energy consumption. Need is for sustainable wastewater treatment technologies to locally treat the sewage and also reuse. Substantial efforts are being made to document, understand, and explain the science behind these issues all over the world. Biological degradation of recent biomass and of organic chemicals in wastewater treatment proceeds either in the presence of molecular oxygen by respiration, under anoxic conditions by denitrification, or under anaerobic conditions by methanogenesis

or sulfidogenesis. Anaerobic digestion of sewage wastewater using microorganisms is an effective means but the results does not meet the discharge standards The Down-flow Hanging Sponge(DHS) Bio-Tower based on anammox process in combination with UASB (Upward Flow Anaerobic Sludge Blanket) Fig.-1 is one of the economically attractive innovative system for sewage treatment & well suited for tropical and subtropical countries. The DHS Bio reactor employing different sizes of sponge media exhibit excellent performance in removal of BOD, COD and also a significant decrease in ammonium nitrogen at a fixed hydraulic retention time. Wastewater is trickled from the top of the reactor and allowed to flows vertically down through the reactor containing microorganisms retained both inside and outside of the sponge media. The results of investigations show a tremendous decrease in BOD and COD (up to 87 - 93%). It is further observed that smaller sponge media produced better removal efficiencies this may be due to better oxygen uptake in the stream flowing down through reactor. The efficiency of BOD & COD degradation for the bulk mass in concentrated wastewater or degradability of organic pollutants generally seems to be about similar in aerobic or anaerobic bacteria. However, the degradation rates is faster in aerobic treatment procedures than in anaerobic treatment procedures. Anaerobic treatment in general does not lead to the low pollution standards of COD, BOD, or TOC that can be met with aerobic systems and which are required by environmental laws. In present situations Anaerobic treatment of wastewater should be considered a pretreatment process to minimize the oxygen demand and surplus sludge formation in a subsequent aerobic post-treatment stage. Only after a final aerobic treatment the COD, BOD, or TOC concentration limits stated in the environmental laws can be met. If limiting concentrations for nitrogen and phosphate also have to be achieved, further treatment steps such as nitrification, denitrification, and biological or chemical phosphate removal, must be considered.

Abstract. Ni0.8Zn0.2Fe2O4 nano-powders were prepared by solution combustion method by using metal nitrates, citric acid, green fuel (plant extracts). The structural, magnetic characteristics of as prepared, annealed Ni0.8Zn0.2Fe2O4 samples were determined by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), vibrating sample magnetometer (VSM). XRD confirms the formation of single phase nano-crystalline (grain size: 12.7 32.7 nm) cubic spinel structure of annealed samples. Studied mixed ferrite shows relocation of Ni2+, Zn2+, Fe3+ ions between A, B site. Coercivity of annealed samples ranges between 29.7 to 124.9 Oe. Obtained saturation magnetization of annealed samples (34.56 54.96 Am2/kg) is a combined effect of weakening of A-B, A-A, and strengthening of B-B interaction, and surface dead layer (0.80 1.25 nm) on particles, arising due to spin disorder at surface.

Abstract. Inorganic glasses are suitable materials for fabricating active and passive photonics devices. In this work, glasses of compositions 20CdO.xSiO2

.(79.5-x)Bi2O3 (10 ≤ x ≤ 30) doped with 0.5 mol% of Nd3+ ions were prepared through the melt quench method. Optical absorption, fluorescence and FTIR spectra were measured at ambient temperature. A close correlation is observed between the Bi2O3 content and the spectroscopic properties such as Judd-Ofelt intensity parameters Ωλ (λ = 2, 4, 6), radiative transition probability, radiative life time, branching ratio and stimulated emission cross-section of Nd3+ ions and structural properties of prepared glasses. The shift in the hypersensitive band shows that the covalency of the RE-O bond increases with increase of Bi2O3 content, and it is attributed to the increased interaction between the rare earth ions and the non-bridging oxygens (NBO’s). The stimulated emission cross section of fluorescence transition 4F3/2 → 4I11/2 have high values and varies from 14.72 × 10-20 to 9.66 × 10-20 with Bi2O3 content in the host glasses. This results point out this glass system as a good candidate to be used in the development of photonics devices. Further, the FTIR results reveal that the glasses have BiO6, SiO4 and non-bridging oxygen as local structure.

YAA4 Nonlinear Optical Properties of II –VI Semiconductor Core-Shell Quantum Dot

corresponding author:[email protected]

Abstract: Semiconductor Quantum Dots (QDs) have drawn substantial attention for last couple of decades as they are treated as the building block for current optoelectronic and spintronic nanodevices. They have been widely used in various ultrafast optoelectronic devices such as transistors, switches, bistable elements, modulators, lasers, etc. In semiconductor quantum dots the electrons and holes are confined within the width of a semiconductor layer of low energy gap which is surrounded by another semiconductor having higher band gap and is lattice matched with the former. The confinement of electrons and holes give rise to novel optical and electronic properties. Such nanostructures are popularly known as core-shell quantum dots (CSQD). It has been experimentally observed that core-shell quantum dots (CSQD) show more efficient linear and nonlinear optical properties over the bare quantum dot and the thickness of the shell provides additional control on optical and electronic properties of QDs. Some well-known and reported example of CSQD are ZnSe/Zns, CdSe/ZnSe, CdSe/ZnS, CdSe/CdS etc. The knowledge of nonlinear optical properties of quantum nanostructures is very important to design present optoelectronic devices and warrants clear understanding of the mechanisms underlying the material response to electromagnetic radiation. In view of above discussions, here in this study we have explored the role of exciton and biexcitons in the nonlinear absorption of semiconductor QDs under strong confinement regime where the QD size is considered as smaller than the bulk exciton Bohr radius. We have also examine the effect of shell thickness on nonlinear optical absorption in such type of ZnSe/ZnS CSQDs

TH1 Persistence and dissipation of ready pre-mix formulation (Novaluron + Indoxacarb) in/on

tomato (Lycopersicon esculentum Mill.) and its leaching in soil Anita

Department of Chemistry, GDC Memorial College, Bahal (Bhiwani) Corresponding Author: [email protected]

Abstract: A field experiment was conducted to study the persistence behaviour in tomato fruits and soil underneath and effect of processing on the reduction of residues of ready pre-mix formulation (Novaluron 5.25% + Indoxacarb 4.5% SC). Samples of tomato fruits and soil were collected periodically on 0 (1h), 1, 3, 5, 7, 10 and 15 days after applications. Residues were estimated by gas chromatography (GC) equipped with capillary column and electron capture detector (ECD). Per cent recoveries at the fortification levels of 0.01, 0.10 and 0.25 mg kg-1 in tomato fruits and at 0.01 and 0.05 mg kg-1 in soil were in the range of 82-94 per cent depicting validity of methods used for present studies. Limit of detection was 0.005 mg kg-1. Dissipation in tomato fruits followed first order kinetics with half life period from 1.40 - 2.48 days at both the doses of novaluron as well as indoxacarb. Residues decreased substantially during household processing among which peeling was found most effective which resulted 80-89 % reduction. For sandy loam soil under tomato crop, half-life period was found to be in the range of 0.63 to 2.17 days at single and double doses, respectively, for both novaluron as well as indoxacarb following first order kinetics. In leaching experiment carried out under laboratory conditions, 55 - 60% retention of novaluron and 70 - 75% retention of indoxacarb were observed up to 10 cm soil in both the doses, showing their very less mobility in soil. Residues were not detected after 40 cm depth of soil in both the doses. Since, residues of novaluron and indoxacarb were not detected in any of the leachate fractions of soil, hence, these may be safe for soil and ground water contamination.

Abstract:Nanotechnology is a creation of useful materials devices and systems through manipulation of matter on a minuscule scale. A nanometer is a billionth of a meter. Nanotechnology is used in almost every field. Technological advances in the field of nanotechnology have led to advent of a new field of study, nanomedicine , a pairing of molecular biology and medicine. The diagnosis and treatment of disease at molecular level will soon be within our reach. The “ EU-Funded NAMDIATREAM” is working on using nanotechnology to aid in the diagnosis and treatment of cancer. Electronics also get smaller all the time but there is a limit to how tiny they can. But now with the help of nanotechnology we can shrink capacitors, key components that store energy etc. Now,nano scale pillars could radically improve conversion of heat to electricity. This technique is building an array of tiny pillars on top of a sheet of thermoelectric material represents an entirely new ways of attacking a century old problem. Glaucoma is a pervasive disorder that occurs when there is buildup of pressure in life. If left untreated, it can damage the optic nerve, resulting in vision loss. Bio-engineers have developed a nanodiamond embedded contact lens that may improve Glaucoma treatment by localizing and sustaining drug release that can be triggered using tears. The researchers showed that the nanodiamonds even improved lens durability while maintaining wear comfort.

X007 A Review of nanotechnology applications in science

Mamta, Assistant Professor in Physics, Vaish College, Bhiwani

Corresponding author: [email protected] Abstract:Nanotechnology is helping to considerably improve, even revolutionize, many technology and industry sectors: information technology, energy, environmental science, medicine, food safety, and transportation, among many others. Today's nanotechnology harnesses current progress in chemistry, physics, materials science, and biotechnology to create novel materials that have unique properties because their structures are determined on the nanometer scale. This paper summarizes the various applications of nanotechnology in recent decades. The difficulty of meeting the world’s energy demand is compounded by the growing need to protect our environment. Many scientists are looking into ways to develop clean, affordable, and renewable energy sources, along with means to reduce energy consumption and lessen toxicity burdens on the environment. Prototype solar panels incorporating nanotechnology are more efficient than standard designs in converting sunlight to electricity, promising inexpensive solar power in the future Nanostructured solar cells already are cheaper to manufacture and easier to install, since they can use print-like manufacturing processes and can be made in flexible rolls rather than discrete panels. Nanotechnology is improving the efficiency of fuel production from normal and low-grade raw petroleum materials through better catalysis, as well as fuel consumption efficiency in vehicles and power plants through higher-efficiency combustion and decreased friction. Nano-bioengineering of enzymes is aiming to enable conversion of cellulose into ethanol for fuel, from wood chips, corn stalks (not just the kernels, as today), and unfertilized perennial grasses. Nanotechnology is already being used in numerous new kinds of batteries that are less flammable, quicker-charging, more efficient, lighter weight, and hold electrical charge longer. One new lithium-ion battery type uses a common, nontoxic virus in an environmentally benign production process. Nanostructured materials are being pursued to greatly improve hydrogen membrane and storage materials and the catalysts needed to realize fuel cells for alternative transportation technologies at reduced cost. Researchers are also working to develop a safe, lightweight hydrogen fuel tank. Various Nano science-based options are being pursued to convert waste heat in computers, automobiles, homes, power plants, to usable electrical power.

Abstract. Ground water contamination in urban environment is a major issue and is complicated by large number of potential source of contamination. India has wide spectral variations of meteorological, topographical, geomorphologic, hydrological, geological, and hydro geological conditions. The chemistry of groundwater is an important factor determining its use for domestic, irrigation and industrial purposes. Utilization of land varies from place to place due to rapid urbanization and industrialization, without following the strict environmental norms, causing a lot of variation of quality of groundwater within a short distance, which constrains the developmental activities drastically everywhere. In the present study, the geochemical characteristics of groundwater and drinking water quality have been studied. 20 groundwater samples were collected and analyzed for pH, electrical conductivity, total dissolved solids, carbonate, bicarbonate, chloride, sulphate, nitrate, calcium, magnesium, sodium, potassium, Fluoride and total hardness. The results were evaluated and compared with World Health Organization, Rajiv Gandhi Drinking water Mission, NEERI and BIS water quality standards. The studied results reveal that the groundwater is fresh to brackish and moderately high to hard in nature. Na and Cl are dominant ions among cations and anions. Chloride, calcium and magnesium ions are not in the allowable limit except few samples. The piper trilinear diagram shows that groundwater samples are Na–Cl and mixed CaMgCl type. Based on the WQI results majority of the samples are falling under bad category and not suitable for drinking water purposes without treatment.

and poly (p-phenylenevinylene) (PPV) have been synthesized, in free-standing film and bulky powder form, through the electrochemical or chemical polymerization methods. They are easy to prepare in the form of extended surface thin films, and can store the charge throughout their entire volume. During the past decade, there have been many reports concerning fruitful investigations, leading to practical applications of conducting polymers in various fields such as batteries, electrochemical displayers, sensors and catalysis. Recently, many attempts have been devoted to the use of conducting polymers as electrode materials in electrochemical capacitors, often called supercapacitors Especially polyaniline (PANI) and polypyrrole (PPy) have been considered as the most promising materials for this application due to their excellent capacity for energy storage, easy synthesis, higher conductivity and lower cost than many other conducting polymers. However, they have lower cycle life. This has been overcome to some extent by the use of composite structures. High energy and power densities have been reported when ECPs are deposited as a thin coating on some supporting substrate such as carbon paper and cloth. Different kinds of nanotubes, carbon and their composites have been already proposed as electrode materials for supercapacitors. This study describes the formation of composites of polyaniline (PANI)-Carbon Nanotube (CNT) by using an in- situ chemical oxidative polymerization of the monomer in the presence of Ammonium peroxydisulfate as oxidant. Ultrasonication was done for complete dispersion of CNT and for uniform coating of PANI over CNT. The PANI-CNT composites were characterized by FTIR spectroscopy. The FTIR study shows the formation of PANI over the surface of CNT. The crystalline nature of the polymer was characterized by XRD technique. The surface morphology of the composites was characterized by using scanning electron microscopy (SEM). As a result of this study it was investigated that thinnest layer of PANI over CNT can be deposited by using 0.02M aniline concentration in the initial polymerization solution.

Abstract. The circumstance concerning the investigation of the simplex calculation is much more terrible than recommended previously.

ABSTRACT. Dielectric multilayer structures are the choice of passive components in optoelectronic and photonic devices. These passive components are promising for the manipulation of light in an efficient way. Multilayer structures composed of two distinct materials have been investigated as stop band filters in the design and fabrication of solar cells, waveguide, microcavities etc. For optical filters, TiO2 and SiO2 films are the better choices due to their large refractive index contrast. In spite of the various available techniques, the sol-gel spin coating fabrication is one of the easy and inexpensive techniques. Here, we report experimental studies of TiO2/SiO2 multilayers structures prepared with various precursor concentrations. The enhanced precursor concentrations evidenced the increased thicknesses of the individual layers. Reflectance studies of the two multilayer structures endorsed the corresponding shift of the stop band from visible to infra-red wavelength region in accordance with the low and high precursor concentrations. This shifting of stop band is attributed to the increased grain size.

Abstract. A series of color-tunable mixed ligand based zinc complexes with 2, 2’-bipyridine (Bpy) and 8-hydroxyquinoline (q) or 5-chloro-8-hydroxyquinoline (Clq) or 5,7-dichloro-8-hydroxyquinoline (Cl2q) or 2-methyl-8-hydroxyquinoline (Meq) or 5,7-dimethyl-8-hydroxyquinoline (Me2q) was prepared. The prepared metal complexes had good thermal stability. Ultraviolet-visible (UV-Vis) absorption and photoluminescence (PL) emission spectra were recorded in order to inspect the optical characteristics of prepared metal complexes. The synthesized metal complexes showed bright emission on excitation with an UV light source. The emitted light had color coordinates values at x = 0.223, y = 0.476 for [ZnBpy(q)], x = 0.233, y = 0.513 for [ZnBpy(Cl2q)], x = 0.246, y = 0.531 for [ZnBpy(Clq)], x = 0.224, y = 0.456 for [ZnBpy(Meq)], and x = 0.448, y = 0.512 for [ZnBpy(Me2q)] complexes. Temperature-dependence photoluminescence (PL) spectrum of [ZnBpy(Clq)] complex was also studied to illustrate the effect of substituents on the emission intensity and peak position of the emission spectrum. Color tuning by varying the substituents on 8-hydroxyquinoline ligand was analyzed in the prepared complexes. Complexes emitting color tuned luminescence could be utilized for various field emissive devices. Keywords: Zinc complexes, optical properties, color- tunable, light emitting devices.

THERMAL CONDUCTIVITY APPARATUS

The Apparatus follows widely accepted theory of heat conduction in liquids based on Debye’s concept in which the hydroacoustic vibrations (phonons) of a continuous medium (base fluid) are responsible for the heat transfer in liquids. Based on this heat transfer mechanism, Bridgman has obtained a formula, characterized by the direct proportionality between thermal conductivity and sound velocity in pure liquids.

where ν = ultrasound velocity N (Avogadro's number) = 6.02×1023 and V (molar volume) = 𝑚𝑚 𝜌𝜌⁄ K= (Boltzmann's constant) = 1.3807×10-23 J/K Errors are found less than 3% in Nanofluids with modified equation.
