In 2016, the Nobel prize in Chemistry was given to pioneering research on molecular machines. Here, we provide a method to control molecular machines by our hand-like motions Here we propose a novel methodology that controls molecular machine operation, molecular receptor tuning, & life regulation. This concept can be realized at dynamic two-dimensional medium such as thin films at the air-water interface, i.e., Langmuir monolayer because this medium possess both features of bulk and molecular dimension. For example, we successfully manipulated molecular machines at the air-water interface upon bulk (10-100 cm size) motion of the entire monolayer and realized “capture and release” of aqueous guest molecules using molecular machine. By mechanical tuning of molecular receptor, mechanically controlled chiral recognition of amino acid and discrimination of nucleosides by the supramolecular monolayer was successfully demonstrated. Thermodynamic calculations revealed applied forces and energies at these interfacial processes are much smaller than those for light stimuli and related physical inputs. As shown in figure below, this weak force technology at interfaces would enable us to tune molecular conformations for optimized functions, which are fundamentally different from two major concepts (one stable state and switching) Applications of the interfacial technologies to bottom-up synthesis of 2D materials and cell fate control using water-perfluorocarbon will be also presented.

Future of Energy: Gas Hydrates

Prof. Rajnish Kumar Department of Chemical Engineering

IIT Madras, Chennai, INDIA email: [email protected]

Invited Talk - 04

Methane clathrate (also known as gas hydrates) is an unconventional fossil fuel energy which is a source of methane gas, trapped in crystalline ice like structure in permafrost regions and beneath the sea in outer continental margins. As per recent estimates, total amount of carbon in methane hydrates, far exceeds the carbon content in all the fossil fuel reserves put together and hence natural gas hydrates has potentials to become the future of fossil fuel. This presentation briefly takes up the issues related to understanding of gas hydrates at molecular level, its energy potential and exploitation options. We compare the four approaches by which methane could be recovered; a basic idea of depressurization, thermal stimulation, additive addition and replacement of methane by carbon dioxide would be discussed with experimental data from lab scale and bench scale studies.

Prof. Rajnish Kumar is an Associate Professor in Chemical Engineering Department at IITM. He holds a PhD degree in Chemical Engineering from The University of British Columbia, Canada. His research interests are unconventional energy, carbon dioxide capture, process development and scale-up. His research work has so far resulted in close to 80 referred publications with an h-index of 35. Rajnish is recognized as “highly cited researcher” from Clarivate Analytics. He has also received NASI – Scopus Young Scientist Award in 2016. Resources: https://scholar.google.co.in/citations?user=P21tbTMAAAAJ&hl=en https://che.iitm.ac.in/?page_id=386

AI-based applications and its benefits for the NE States

Dr. Y. Jayanta Singh Director, National Institute of Electronics & Inf Tech. (NIELIT), Guwahati


Invited Talk - 05

Artificial Intelligence (AI) can give solutions for better ‘Roti Kapda aur Makaan’. AI helps us in the reduction of errors and increasing the accuracy and in automation processes in various businesses. The ‘Industry 4.0’ already suggested converting all services to digital services that will have very less human intervention. For example, a worker should know how to operate the CNC machine for cutting metal instead of using his manual labour. During this Covid19 era, digital services have turned out to be the need of the hour. Small states can plan many AI-based businesses to improve the socio-economic condition in the selected sectors such as Academic, Agriculture, Health, Tourism and Waste Management etc. In Academic, Post COVID-19, all are expected to be digital literate. There are several issues, but the corresponding possible solutions are the new business opening for IT players. Some issues are poor connectivity, hidden cost due to high data usage, poor audio-video quality etc. Also, the qualities of digital services tend to deteriorate and loose competency when a number of users vastly increases. So, a re-engineering is an importance by adopting the best services of User Interface (UI) and User Experience (UX). Teachers need to adopt a Flipped classroom or Blended modes etc. This is another new business opening. In Blended mode, the candidates learn via electronic/online media as well as face-to-face teaching. In a Flipped classroom, the users have to engage with materials – in online or other mode followed by in-class activities that involve peer learning, small-group work. Good actions to flip are - discussions, debates, Q&A, demonstrations, simulations, peer tutoring and feedback, and role-playing etc. Likewise, examinations demand new ways. This is also another new business. Now the Proctored examination will be one best option. A proctor is an officer who monitors candidates during a test. In an Online proctored test, someone will be watching the examinee using webcam or CCTV camera, or remote devices with strict timer-based control. Another option is an Online Open Book examination (OBE), where the candidates are allowed to use some resources during the test-textbook and lecture notes. However, the questions are set to test on the synthesis, analysis, and application, rather than memorization. Job recruitment and Skill assessment to new ways will come up, where the Recruiters will check the 'Digital Skillset’ and capacity to interact with peer and handle the customers using ICT tools. Today, many firms have adopted online verifications. In Agriculture, the Cloud-based available soil health data can be provided to farmers. If required, the state-level soil testing can be done choosing samples in each district by recording the coordinates of the fields. The farmers can choose the best suitable crop based on the season, and the soil condition provides on the cloud. The State authority will know the types of crop and possible usage of fertilizers, pesticide etc. Also, the information on crop census, so that e-market is ready to help the farmer connecting to the customer anywhere, and anytime. The Cloud cum solar-based Water pump can be facilitated to the farmer. They can use mobile apps to know the water level, and the same apps can be used to 'start or stop' the pump without visiting the fields. The state authority can predicate the possible crop census, and necessary steps can be arranged for better serving of the citizen. In the Health sector, the AI-based process or robots to serve the patients better. Manage the imported medicine data and link with the medicinal plants available in the state, to attract more paramedical firms can be set up in the country. AI or cloud-based Health care monitoring system can be set up to monitor or advice citizen in public using the radio or TV. Proper collections of the data are requiring. In Tourism, Digital tourism and booking through a Govt sector to analyzed the customer behaviours. It will show the most attractive region of a spot, in a dashboard and website to attract more tourists.

(contd….) State waste management is another new business, where AI can help in proper management and reduced associated the health hazardous. Solid waste becomes a critical issue, and its direct impact on human health and environment makes it a crucial one. These problems arise due to improper management of waste bins. This process can be implemented using the proximity sensors to show fill of the dustbin, and the state can decide to start some recycle units. Remote Sensing (RS) or Satellite image of the study area is required for the site selection process, and it covers a large region. GIS helps in creating geo-database for providing the inputs to make a decision and to see the state situation at a glance. The RS technique can provide a rapid and efficient approach to identify suitable dumping place in real-time. GIS can help in maintaining data to facilitate collection operations such as analyzing optimal locations, planning routes for vehicles transporting waste from residential, locating new landfills and monitoring the landfill, etc. GIS will provide a digital data bank for future monitoring programme of the site. It will give SMS trigger facility in the Bin to inform the authority the amount of waste collected with date and time. It will assist local administrators related to future town or city planning- clustering of the bins, optimization of routes for pickup van, analysis of the amount of waste generation, capacities of dumping site or processing units (if any) to convert to new business etc. All the above processes can be implemented, monitor and predict the business using AI-based practices. The dashboard may be displayed to the public to show the customer of the number and collect feedback and visualization of similar types of business.

Over the past several years, there has been an extraordinarily rapid growth in our knowledge of free radical chemistry and its possible involvement in both normal essential biology and age related diseases and dysfunction. The oxygen molecule, which is essential for human beings and for many forms of life, is also responsible for the deterioration of organic molecules exposed to air. Oxidative stress is characterized by the presence of unusually high concentrations of toxic reactive species, which are formed by interaction of singlet molecular oxygen (SMO) with free radicals, such as, reactive oxygen species (ROS), reactive nitrogen species (RNS), reactive nitrogen oxygen species (RNOS), and unbound adventitious metal ions. Several classes of biological molecules are susceptible to attack by 1O2, including several protein amino acids–cysteine, methionine, tryptophan, and hystidine–with the possible consequences of enzyme inactivation. Membrane disruption, a common feature of photodynamic action, is due to lipid peroxidation initiated by the formation of hydroperoxides from the reaction of 1O2 with unsaturated fatty acids. The most efficient naturally occurring physical quenchers of 1O2 are the carotenoids. Antioxidants, scavenge for free radicals, and consequently, are a very special group of nutritional supplements. They are very special because they play such a very important role in protecting the body from the formation of very dangerous substances referred to as free radicals. Antioxidant activity is essential for life, to counter act the strongly oxidizing environment in which we live. Many biological functions, such as protection from mutagenesis, carcinogenesis, and aging, among others, are due to antioxidative effects. Synthetic antioxidants, such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) have restricted use in foods and are suspected to be carcinogenic. Therefore, the search for natural antioxidants (NAO), especially of plant origin, has greatly been increased in recent years. In order to find new sources of natural antioxidants, antioxidant activities of medicinal plants associated with prevention and treatment of diseases were evaluated using various techniques. Herein, the isolation and characterization of natural antioxidants (NAO) from certain medicinal plants will be highlighted. Antioxidant activities of the extracts and compounds isolated from the plants of Zingiberaceae family, Smilax lanceaefolia, Ficus pomifera Wall., Crassocephalum cepridiodes (Benth) Moore., Strobilanthes flaccidifolius Linn., Ficus hispida Linn., etc. were determined and will be reported.

Invited Talk - 08

Economic growth is largely the outcome of entrepreneurial initiative. Entrepreneurs exploit opportunities, convert ideas into viable business plan, provide new products and services to the society by bringing together and combining various factors of production, and help alter life style of the people. Entrepreneurs are seen as creators of businesses, which in turn, produce income and output and generate employments. Manipur among the eight North Eastern States of India is rich in natural resources including Agri-horticultural products – naturally organic produce. However, the technology of processing and preservation for value addition of these agro resources still remains in low level of operations. Empowering the local population to produce the value added products – production by the masses will have positive impact in these regions in terms of economic benefit by the growers, health benefits by the population and employment generation. However, the major constraints that need to be addressed for sustainable food processing industries are improved secondary and tertiary food processing; adopting appropriate technologies, advanced equipment and innovative product development at the industry level; planning of logistics; networking between industries and R&D Institutes and employing qualified and highly skilled manpower, etc. Entrepreneurs and start-ups can play responsible roles to address these problems. The presentation will provide the entrepreneurial opportunities in food processing sectors for the benefit of new-entrepreneurs or start-ups in the state.

Repurposing of beneficial bugs for new molecules

Dr. Syed G Dastager Principal Scientist

Invited Talk - 11

Drug resistance continues to be a significant cause of mortality and morbidity worldwide. The emergence of drug resistant is considered a public health crisis, with some strains now resistant to all available drugs. Emergence of multi-drug resistant (MDR), extensively drug resistant (XDR) and now totally drug resistant (TDR) strains is on the rise globally. It is widely accepted that actinobacteria are prolific producers of natural bioactive compounds. We argue that the likelihood of discovering a new compound having a novel chemical structure can be increased with intensive efforts in isolating and screening actinomycetes and their previously under-represented genera from unexplored environments, it can be an interesting source for new candidate drug against infectious diseases. Unfortunately, the growing burden of antibiotic resistance is coupled with decreased effort in the development of new antibiotics. Actinomycetes have provided us with different classes of antibiotics that play a critical role in treating infectious diseases. This is mainly due to their capacity to produce versatile bioactive secondary metabolites through their resourceful biosynthetic gene clusters. Biodiversity guided expansion of existing microbial strain collections are seen as one of the most promising ways forward for generating novel antibiotic scaffolds. Coupled to more sophisticated screening efforts for bioactivity and more comprehensive analysis of each species for its potential to generate novel scaffolds of natural products. We hypothesized that, those ecological biodiversity hotspots could harbours new strains of actinomycetes will lead the novel drug candidate to tackle antibiotic resistance problem.

Invited Talk - 14

International marketing is the application of marketing principles by industries in one or more than one country. It is possible for companies to conduct business in almost any country around the world, thanks to the advances in international marketing. International marketing is now in the midst of a major transformation that, in the next 15 to 20 years, will reshape and restructure concepts, approaches, and operations. International marketing management thinking may well be turned upside down, as fundamental precepts are challenged, a more practical mindset evolves, and new tariff or non tariff barrier decides the success of the international trade. International concerns will move to the forefront of business, with government and societal issues transforming the management of marketing activities. As a speaker in this KUHMANG 2020, I would like to offer some perspectives on the future of international marketing practices based on some current trends.

We have prepared various semiconducting nanomaterials such as SnO2, ZnO, APO4 (A = Y, La, Gd), AVO4, CaMoO4 and PbSe using co-precipitation methods. These materials can absorb light in UV, visible or NIR or IR region. Depending on size of particles, absorption band can be changed. For example, PbSe quantum dots (QDs) can change its absorption band from 600 nm to 3000 nm due to strong quantum confinement possessed by the material. After absorption of sufficient energy, it can produce the electron-hole recombination leading to emission in visible-NIR region. Most semiconducting nanoparticles have large absorption cross sections and their emission bands are also broad. However, lanthanide ions (Ln3+) show very low absorption cross-section, but their absorption and emission transitions are sharp due to f-f transitions. When a few percentages of Ln3+ ions are doped in the host semiconductors, there are a possibility for energy transfer from host to Ln3+ as well as decrease in concentration quenching among Ln3+ ions; and thus enhanced emission intensities of Ln3+ occurs. In view of this, we have prepared Ln3+ doped semiconducting materials, which are able to show emission in visible as well as NIR range. Also, UV and visible emission can be produced by absorption of NIR light through Up-conversion process. NaYF4:Ln3+ Up-conversion nanoparticles have been prepared and investigated their emission properties using 980 nm CW laser. The bio-imaging properties using lanthanide doped semiconductors were investigated in different cell-lines. In addition, optical display, temperature sensing, light harvesting, photothermal therapy, anti-counterfeit ink, and optical switching were investaged using various nanoparticles. Using persistent luminescence nanoparticles, the distribution of nanoparticles in the different organs of mice can be traced for about 2 hours and this study will help in alternative way to radio-isotopes based diagnosis.

Invited Talk - 17

New generation nanoscale systems that utilize remotely active as well as controlled drug release was established in order to enhance the cancer therapeutics. Although many existing nanodrug carriers have shown numerous advantages, their efficacy is largely constrained by their lack of the ability to achieve on efficient demand drug release. In light of the growing interest in the search for next generation effective solutions for cancer treatment, we designed novel magneto-thermally active nanocarrier in which the drug release can be activated on demand upon exposure to a magnetic field. Magnetically active graphene oxide/iron oxide nanocomposite that can be triggered using magnetic hyperthermia initiated from an external alternating magnetic (AC) magnetic field. The unique remotely-triggered functional nanocomposite with well-defined size and uniform distribution were designed. The synergetic effect of both the drug and magnetic hyperthermia is observed in the killing of the cancerous cells. The overall simplicity of action, durability and biocompatible nature of nanocomposite demonstrated herein are key for successful tumor cells targeted therapeutic systems for the kinds of cancer therapy being sought for modern personalized and precision medicine.

Oil & Gas Exploration in Manipur

Mr Chanam Kulabidhu Wellsite Petroleum Geologist,

Cairn Oil & Gas, INDIA email: [email protected]

Invited Talk - 18

Manipur’s name appeared in the discussion for Oil and gas exploration first in the year 2003 when Government of India through its Ministry of Petroleum and Natural Gas listed a block in Manipur - (AA-ONN-2002/2), covering an area of 3850 sq km under the IVth round of New Exploration Licensing Policy (NELP). However no bids were received from any interested companies. Later in 2009, under the VIIIth round of NELP, two blocks with a total area of 3957 sq km - Block 1 (AA-ONN-2009/1) consisting of 2217 sq km and block II (AA-ONN-2009/2) with an area of 1740 sq km were listed. After the bidding process, the two blocks were awarded to Jubiliant Oil and Gas Private Limited (JOGPL), a Netherlands based company for exploring and drilling the two blocks in Jiribam, Tamenglong and Churachandpur districts. The contracts were signed in 2010. JOGPL contracted Bell Industries to undertake a 5,273 line km airborne full tensor gradiometer (FTG) survey and was completed in November 2011. The processing and interpretation of the resultant data was completed in April 2012. Asian Oil Field Services started the seismic survey for JOGP in 2011. The minimum work commitment totalling 1,000 line-km on both blocks was to be completed by November 2014. After the seismic survey and data processing, 30 well locations were identified for drilling exploration wells. However due to local issues, operation was suspended and no drilling activity has started yet in Manipur. In another development, under the national seismic program formulated by the Ministry of Petroleum and Natural gas, Directorate General of Hydrocarbon (DGH), a regulatory body identified 1315 line Km for Manipur as a part of the 42243 line km 2D seismic data for appraisal of the un-appraised Indian sedimentary basins. The survey was to be conducted between 2016 to 2019. Oil India ltd (OIL) contracted the seismic survey to Asian Oil field services. The work started in 2017 but was stopped after conducting 4.74 line km only due to local issues.

Mr Kulabidhu Chanam has been working extensively in Oil and Gas exploration industry for more than 24 years in more than 9 countries. Currently he is working as a Consulting Wellsite Geologist to Cairn Oil and Gas, India. He obtained M.Sc. in Petroleum Technology from Pune University in 1994.

We need a method affordable to poorest of the poor for detecting water before drinking. So application is vast, related to health of 239 million people. The need of the hour is to have a quick testing of water whether it contains Arsenic by any person with the colour change of the paper strip which any poor person also can afford. If it contains Arsenic, next question is, how much?. That can be tested by an instrument, which we are in the process of development. A general overview about the development of sensors like detection of explosives, glucose in human sweat, instant blood clotting bandages will be shared in the presentation.

Dr Niraj is presently working as Senior Scientist at CSIR – National Chemical Laboratory, Pune. He has done his PhD in Chemistry from Manipur University.

Microbiology of Lonar soda lake, India; lessons learnt on conservation perspectives

Mahesh Dharne Principal Scientist, and Associate Prof. AcSIR,

National Collection of Industrial Microorganisms (NCIM), CSIR-National Chemical Laboratory, Pune, India


Invited Talk - 20

With accelerating population and pollution, xenobiotics are introduced into terrestrial, aquatic and marine environments through industrial, agricultural and domestic activities and are persistent in nature and have antagonistic effects on the environment, flora, fauna and mankind. In India, the hypersaline and hyperalkaline Lonar Lake located in Maharashtra is a natural meteorite lake, geographically comparable to Martian basaltic craters. Recent reports indicated surge in anthropogenic activities that resulted in deposition of xenobiotics in the lake, disrupting the growth of inherent bacterial population and increasing algal growth. We stated the hypothesis thus states that, seasonal changes play a key role in regulating the nutrient availability and physicochemical characteristics of the lake, governing the microbial community diversity and functional aspects. Increase in temperature in pre-monsoon sometimes leads to increased salinity and alkalinity, affecting the autochthonous microbial population of the lake. During last few years, we have been monitoring such lakes for microbial community changes during different seasons, understanding geo-chemistry of lake and functional analyses of antimicrobial resistance genes and bioremedation genes in the lake ecosystem (Chakraborty et al., Ecological indicators, 2020; and Chakraborty et al., Ecotoxicology and environmental safety, 2020; Chakraborty et al., Chemosphere 2020). Our efforts emphasize on conservation of lake ecology by enforcing strict measures on anthropogenic activities.

Bacteria vs Humans: The struggles of our species to overcome theirs

Dr. Akshay Manohar Infectious Diseases Specialist

Southeastern Center for Infectious Diseases, Tallahassee, Florida, USA email: [email protected]

Invited Talk - 22

The discovery of penicillin in 1928 was the first glimmer of hope humankind had against one of the biggest causes of human mortality: infection. But microorganisms, especially bacteria have also been fighting back with increasingly resistant and virulent strains that have evolved from excessive exposures to antibiotics, many of which have been consumed unnecessarily and incorrectly. Today, not even 100 years since the first antibiotic, we are facing challenges with infections for which there are few or no medications. However, newer drugs and techniques to fight infections are being researched at labs around the world, and we are working our hardest to keep up the fight and not lose our last hope against our microbial predators.

Invited Talk - 23

Marine organisms produced several secondary metabolites that find applications in pharmacology and other biological systems. The vast biodiversity and the unique environmental conditions endowed with the marine ecosystem provides marine organisms as the rich sources of various fascinating molecules. It is estimated that more than 15,000 secondary metabolites have been discovered from marine organisms and studied their chemical and biological properties. Majority of these secondary metabolites isolated are from invertebrates, particularly, sponges although substantial number of compounds were also reported from flora and microbes. Notably, sponge alkaloids remain one of the most interesting subject in marine natural Products (MNPs) due to their chemical diversity and wide range of biological activities. Herein, potential of MNPs in pharmaceuticals, MNPs derived from marine sponges, algal metabolites and chitosan extracted from shellfish with biological properties will be discussed. Further, the scope of chemical modification of chitosan to obtain biocompatible and water soluble derivatives and selected synthesis of MNPs analogues to address the supply issue and enhance bioactivities will be highlighted.

Nanoparticles for High Field Magnetic Resonance Imaging Application

Prof. Anurag Gautam Department of Chemistry,

Geethanjali College of Engineering and Technology, Cheeryal, Hyderabad, Telangana-501301, India


Invited Talk - 25

In the near future there would be a need for a high field MRI contrast agent for the MRI diagnostic due to the several disadvantages of Gd-based complexes, such as short circulation time and decrease in efficiency at high magnetic field i.e., greater than 3 T. The lanthanide-based nanoparticle can be an alternative to these complexes due to a high density of metal ions per unit of contrast agent. The high density of the metal ions will enable the MR signal shortening usually, at lower concentrations compared to chelates that typically are used at micro-molar concentrations. Additionally, the nanoparticles would retain their relaxivity efficiency at high magnetic field greater than 3 T.

Why is Asia-India Monsoon Weaker on the Face of Global Warming? – A Climate Change Research for Science and Society.

Dr. Huidrom Narendra Singh

Indian Institute of Tropical Meterology (IITM), Pune, INDIA email: [email protected]

Invited Talk - 26

Understanding the science of climate change as well as the impact of rising trend in global tropospheric temperature on environment, hydrometeorological services and society are important problems of contemporary research because of its strong influence on the socio-economy. A country like India where the economy is largely impacted by the agriculture, the study of long period area-average rainfall series of smaller units like physiographic regions/ river basin scale is highly demanded for adaptation and mitigation processes to be taken up by the decision making authority. During 1979-2018, the number of monsoon storms/depressions over Arabian Sea, Indian landmass and Bay of Bengal has decreased from eight to four, and the all-India monsoon rainfall from 923.1mm to 881.5mm (-4.51%) as compared to 1949-1978. The present investigation is to understand the possible cause of weakening of the thermally driven monsoon circulation in the era of the global warming. Different real time isobaric level tropospheric parameters (viz. MSLP, Surface Temperature, Precipitable water, geopotential height at different isobaric levels, temperatures at different isobaric levels, zonal & meridional winds at different isobaric levels, etc) across the globe obtained from the NCEP-NCAR have been analyzed for better understanding of the monsoon system and its associated rainfall across India. Though rising over different climatic zones, the temperature over the Southern Hemisphere is rising at a faster rate than that of the Northern Hemisphere resulting into reduction of the tropospheric temperature gradient (TTG) from Northern Hemisphere to Southern Hemisphere. The Indian summer monsoon season (June through September) tropospheric temperature (1000-200 hPa) over the globe has increased by 0.59°C from 1949-1978 to 1979-2018, however the rise is more over the southern hemisphere (0.87°C) than the northern hemisphere (0.32°C). During this period, the troposphere has shrunk by 60m over continental Asia and inflated by 90m over oceanic south temperate region. The sea surface temperature has decreased by 0.2° to 0.62°C over northern North Pacific and increased by 0.2°C to 0.8°C eastern South Pacific (west of South America). Over continental Asia the increase in the mean sea level pressure has been observed by 1 to 7-hPa whereas decreased by 1 to 7-hPa over south temperate regions. The main effect of this reduction in the north-south thermal contrast seems to modulate the weakening intensity of Asia-Pacific monsoon circulation and hence decrease in the all-India monsoon rainfall. Being the agriculture, drinking water, and energy production are mainly dependent on the Indian summer monsoon rainfall, the changing spatio-temporal rainfall variability may pose additional stresses on ecological and social life to most of the population. Substantial adverse effects in India are expected due to the changing global climatic scenario that impacts the natural ecosystems. Though there has been a large-scale decline in rainfall in the recent period, the survival of water systems is reasonably well suggests better management practices for water bodies adopted by the people to combat twin problems of flood and drought. Adaptation to climate change can reduce many of its adverse impacts and can lead to enhanced benefits.

Laboratory to Society: Role of Nanoscience and Nanotechnology

Prof. K Kiran Kumar Sharma Deputy Director

School of Nanoscience and Technology, Shivaji University, Kolhapur, Maharashtra 416004 email: [email protected]

Invited Talk - 27

Nanoscience and Nanotechnology is foreseen to contribute to major changes to the global economy, workforce, and way of living. It has been one of the most talked about industries of the last few years. The predicted value of US$173.95 billion globally by 2025, this fast-moving sector is already delivering major sustainability, health and well-being benefits to society. Applications range from automotive, computing, electronic, cosmetics, sports and healthcare industries all benefit from nanotechnology innovations. New fields have also emerged, such as nanomedicine, which aims to dramatically improve our future ability to treat disease. New electronic devices and the means to fabricate them to materials for health and environmental uses. Some nanotech products are already on the market while others are decades away from realization outside the lab. Unlike the transistor or steam engine, nanotechnology is not a single material and are concerned with the development of new technologies at the size scale of about 1 to 100 nanometers. The main reason being, at the nanoscale, the physical, chemical, and biological properties of materials differ from those of individual atoms or bulk matter. The nanoscale is an intermediate regime where classical physical laws overlap with quantum effects and hence nanotechnologies involve creating structures and devices that have novel properties, applications, and behaviour because of their intermediate size. Further, nanotechnologies are based on the ability to precisely control and manipulate these materials and devices on the atomic or near-atomic scale. Therefore, commercialization of nanotechnology as of today, however suffers from several fundamental killing problems that may slow its realization as the platform technology of the 21st century. The bottlenecks and problem face for development of nanotechnology based products for society will be discussed with emphasis on Virus Kavach Fabric Spray Technology, which can deactivate >99% of bacteria and SARS-CoV2 virus.

Sustainable Distillation Technologies for Process Industries

Dr. Nilesh A Mali Sr. Scientist

Chemical Engineering & Process Development Division, CSIR-National Chemical laboratory, Pune, INDIA


Invited Talk - 28

Distillation is one of the most preferred separation technology used in various process industries. Although, it is quite mature technology when it comes to its application in continuous purification operations, it is quite energy intensive. Process industries spends significantly on downstream processing involving series of distillation columns to recover all unreacted reactants, product and byproducts in a pure form. Hence, to be competitive in today’s global market, industries are focusing on developing sustainable distillation technologies which will be quite energy efficient with less foot-print and capital investments. The talk will cover the fundamentals of distillation unit operation till advanced configurations worked out by various researchers to make distillation more efficient and cost-effective. Various fine and specialty chemical industries are also facing problems for separation of close-boiling and azeotropic systems which are difficult to separate using conventional distillation column. A basic understanding of vapor-liquid-equilibrium (VLE) behaviour is necessary in these cases to come-up with advanced distillation configuration like Extractive Distillation (ED). In ED, a external component is added to the mixture to be separated which alters VLE of the system to overcome the azeotropic behaviour and aids sharp separation of the components. Other advanced distillation configuration to improve energy efficiency of distillation includes Thermally Coupled Distillation (TCD) systems. These are quite intensified configuration of distillation leading to significant space and energy saving. Overall the talk will review the current state of art for advanced distillation technologies which are being considered by various process industries to make their separation operation sustainable.

Invited Talk - 29

The greatest challenges humankind is facing today is the access to contaminated free water. Ever increasing human population has led to quantum jump in the use of water. This also resulted in the increasing generation of wastewater. The wastewater which are treated in wastewater treatment plant for making it suitable for release into the environment are very expensive to maintain and not efficient. The treated wastewater is known to contain high levels of heavy metals, and some of these metals are classified as an important class of human carcinogens. The recent advances in phytoremediation, where living green plants are used for in-situ risk reduction for contaminated soil, sludges, sediments, and wastewater through contaminant removal, degradation, or containment which is low cost, eco-friendly and sustainable. The Rhizofiltration technique uses the plant roots to remove metals from effluents wastewater. The tannery effluent is well known to contain high levels of Cr in the wastewater, which is very harmful for the environment. Pilot scale design of aquatic macrophyte treatment system (AMTS) using rhizofiltration technique for management of tannery effluent for irrigation use were adopted using Typha latifolia, Phragmites australis and Eichhornia crassipes. The AMTS technique were observed to removed 72% (approx.) of the Cr from the wastewater effluent. The rhizofiltration technique can be used for the removals of heavy metals from treated wastewater.

Bisbibenzyls - bioactive components from liverworts

Miroslav Novaković University of Belgrade – Institute of Chemistry,

Technology and Metallurgy, National Institute of the Republic of Serbia, SERBIA email: [email protected]

Invited Talk - 31

The bryophytes are plant organisms placed taxonomically between the algae and the pteridophytes. There are about 23 000 species worldwide, and they are further divided into three phyla, the Bryophyta (mosses; 14 000 species), the Marchantiophyta (liverworts; 6000 species), and the Anthoceratophyta (hornworts; 300 species). Scientists propose that liverworts are the earliest plants, evolving 472 million years ago, so these are the ancestors of all land plants that we now know. Among the bryophytes, almost all liverworts possess cellular oil bodies, which are membrane-bound cell organelles that consist of ethereal terpenoids and aromatic oils suspended in a carbohydrate- or protein-rich matrix, while the other two phyla do not. These oil bodies are very important biological markers for the taxonomy of the Marchantiophyta.While polyunsaturated fatty acids and triterpenes are chemical markers for mosses and neolignans for hornworts, bisbibenzyls are chemical markers for liverworts. Chemical investigation of African Marchantia debilis from Cameroon revealed four bisbibenzyls perrottetin E, marchantin C, marchantin Q and 1’-methylmarchantin Q. Last two represents interesting quinone-type bisbibenzyls. Lunularia cruciata (L.) Dumort. ex Lindb. (Lunulariaceae) is a thalloid liverwort distributed commonly in western and southern Europe, where it is native to the region around the Mediterranean. From the methanol extract of L. cruciata seven new bisbibenzyls was discovered. Three of them belong to perrottetin-type and four are riccardin-type bisbibenzyls. Additionally, six previously reported compounds, one bibenzyl and five bisbibenzyls, were also isolated. Cytotoxic activity of all of the isolated compounds against two human cell lines, A549 (lung carcinoma) and MRC5 (healthy lung fibroblasts), was investigated. Two new bisbibenzyls and known riccardin G were the most active. The most abundant bisbibenzyl from the L. cruciata methanol extract, perrottetin F, was biotransformed using Aspergillus niger. Three new metabolites were isolated using reversed-phase semipreparative HPLC and their structures established to be 8-hydroxyperrottetin F, C-7-C-8 cleaved product, and perrottetin F 6'-sulfate using 1D and 2D NMR, HR-ESI-MS, IR and UV spectroscopy. They showed remarkable ability to inhibit synthesis of bacterial quorum-sensing signal molecules such as short chain acyl homoserine lactones (AHLs). Although bisbibenzyls are unambiguous chemical markers of liverworts, one of them, riccardin C was found (in 2007) for the first time in higher flowering plant, Primula veris ssp. macrocalyx from Siberia, Russia. Our investigation from 2020. confirmed the presence of riccardin C in P. veris ssp. macrocalyx from Russia and Iran as well, but also in two Serbian species P. veris ssp. veris, and P. auricula. Besides riccardin C, two new bisbibenzyls were also discovered in Serbian species, 8’-ketoriccardin C and 8’-hydroxyisomarchantin C.

Participation of endogenous circadian rhythm in photoperiodic time measurement during ovarian responses of the subtropical tree sparrow, Passer montanus

Dr Namram Sushindrajit

Assistant Professor Department of Zoology, Cotton College, Guwahati, Assam


Resonance experiment was employed to investigate the mechanism of photoperiodic time measurement during initiation of ovarian growth and functions in the subtropical population of female tree sparrow (Passer montanus) at Shillong (Latitude 25 degrees 34 'N, Longitude 91 degrees 53 'E). Photosensitive birds were subjected to various resonance light dark cycles of different durations such as: 12-(6L:6D), 24-(6L:18D), 36-(6L:30D), 48-(6L:42D), 60-(6L:54D) and 72-(6L:66D) h along with a control group under long days (14L:10D) for 35 days. Birds, exposed to long days, exhibited ovarian growth confirming their photosensitivity at the beginning of the experiment. The birds experiencing resonance light/dark cycles of 12, 36 and 60 h responded well while those exposed to 24, 48 and 72 h cycles did not. Serum levels of estradiol-17beta ran almost parallel to changes in the follicular size. Further, histomorphometric analyses of ovaries of the birds subjected to various resonance light dark cycles revealed distinct correlation with the ovarian growth and the serum levels of estradiol-17beta. No significant change in body weight was observed in the birds under any of the light regimes. The results are in agreement with the avian external coincidence model of photoperiodic time measurement and indicate that an endogenous circadian rhythm is involved during the initiation of the gonadal growth and functions in the female tree sparrow

In a typical experiment, the chemical polymerization is carried out with 1M HCl solution and ammonium persulphate as an oxidant. The deposition of thin films is carried out by dip coating technique. The quantity of MWCNTs was varied 5 to 25mg. The uniform layer of PANI was formed on the external walls of the CNTs. The gas sensing performance of PANI/CNTs for the trace level detection of Ammonia gas (NH3) was carried out. The PANI/CNTs nanocomposite thin film sensor with 15mg addition of CNTs shows excellent gas response towards NH3 gas with enhanced response and recovery time. Furthermore, studies on gas concentration, response and recovery time etc. were performed. The sensing results reveal that PANI/CNTs nanocomposite sensor is one of the potential candidate for the sensitive and selective detection of NH3 gas. Key words: thin film; nanocomposite; polymerization; gas sensor. References: 1. H. J. Salavagione, A. M. Diez-Pascual, E. Lazaro, S. Verab M. A. Gomez-Fatou, J. Mater. Chem.

Nuclear emulsion with its excellent spatial resolution and high efficiency for the detection of charged particles is observed for studies of high energy hadronic interactions. The analysis of the multiplicity distributions of secondary charged particles produced in interactions of cosmic ray nucleons in nuclear emulsion at high range of energy and compared with machine range of energy. It has been observed that the charged particle multiplicity and angular distributions in nucleon-Emulsion nuclei interactions can well be described by the hydrodynamical model. The distributions can be parametrised for the integral angular distributions.The signature for nuclear multiplicity scaling is also evident from the multiplicity distributions. The multiplicity ratio shows the non-dependence of target nucleus which implies the basic mechanism of particle production in both the nucleon-emulsion and nucleon nucleon interactions. KEY WORDS: Shower particle, Nuclear Emulsion, Pseudo-rapidity distributions, Integral angular distributions and multiplicity scaling.

Zingiberaceae family of plant is well-known for its medicinal and economic significances. They have been used as sources of indigenous medicines, vegetables, food flavours, spices, dyes, condiments as well as ornamentals. Study on the solvent extract of this plant (particularly rhizome) offers many opportunities to investigate the various functions and prospects in various pharmaceutical parameters. In spite of the considerable research activities of these plants, the potential has not been fully explored. Present study deals with evaluation of antioxidant, antibacterial and antifungal activities of sequential solvent extracts of rhizomes of Curcuma caesia (CC) using petroleum ether and chloroform. The IC50 values of petroleum ether extract (CC-P) and chloroform extract (CC-C determined by DPPH wasfound to be 0.68 ± 0.02 mg/mland 0.13 ± 0.01 mg/ml.respectively. Antimicrobial efficiency of petroleum ether and chloroform extracts were tested against three Gram-positive bacteria, Bacillus subtilis (MTCC121), Micrococcus luteus (MTCC 106) and Mycobacterium smegmatis (MTCC 6) and one Gram-negative bacteria, Escherichia coli (MTCC 739) using agar well diffusion method. CC-P and CC-C show inhibitory effect against all the bacterial test pathogens used in this study. The ranges of zone were from 10 mm to 18.25 mm. Micrococcus luteus showed the highest sensitivity against CC-P with the zone of inhibition of 18.25 mm whereas Bacillus subtilis showed the lowest sensitivities against both the extracts. And in the antifungal activity tests, both CC-P and CC-C showed positive results against fungal plant pathogen Rhizoctonia solani (MTCC 4633) but failed to show any activity against animal pathogen Aspergillus niger (MTCC 1344). The present study indicated that CC-C extract showed better antioxidant activity than CC-P extract. And in antimicrobial activity, both the extracts showed potent antibacterial activities. Antioxidant and antibacterial potentials shown by both the extracts could lead to isolation of the bioactive compounds for future phytopharmacological applications. Keywords: Curcuma caesia, rhizome, antioxidants, antimicrobial activity, reactive oxygen species, Zingiberacea, Agar well diffusion method, medicinal plants.

Department of Chemistry, Manipur University, Canchipur, Imphal-795003


Citrus maxima (common name – pomelo, local name – Nobap) is one of the important members of the different varieties of Citrus fruits, which grow as wild plants without much nurturing and care in Manipur. The peels of such fruits which continue to pose an environment hazards may be used as rich source of obtaining important essential oils generating wealth from waste. Most of the reported methods are essentially based on steam distillation or hydro-distillation or similar set ups which generally end up getting colorless oils with reduced aroma or semi-mutated oils. We have initiated an effort for the extraction of the essential oil from the peels of citrus maxima (pomelo) with or without a distillation set up for optimum yield. In the present study, we report simple mechanical method of extracting essential oil from the peels of pomelo. We have also designed a hydro-distillation unit for the extraction of the oil. The oil thus obtained are analysed for its chemical constituent from GC-MS and IR spectral studies. The antibacterial properties of the oil in combination with the dispersant or the surfactant has also been studied. It is apparent from the study that the oil possessed significant antibacterial activity. The ternary phase diagram of the oil thus extracted have been constructed using an organic dispersing agent with or without a surfactant. In presence of the non-ionic surfactant TX-100, there is specific region where there is gel formation which is not observed in case of other surfactants.

A series of Eu3+ activated CaW1-xMoxO4 red emitting phosphors were prepared through the hydrothermal method to study the influence of molybdenum ions doping on the luminescent performances of CaWO4:Eu3+ phosphors. X- ray diffraction study reveals the purity of phase and exhibiting the tetragonal phase (Reference no. 00-001-0806). Under 273 nm and 394 nm excitation, all the samples exhibited an intense red emission centered at around 618 nm due to the electric dipole (5D0→7F2) transition of Eu3+ ions, indicating the Eu3+ ions populated the non- inversion symmetry sites in the host lattices. Under 273 nm excitation, the emission intensity increased sharply with the increase of Mo6+ doping concentration but in case of 394 nm excitation, the emission intensity increased and reached its maximum value when x=0.05 and then the emission intensity started to decline. The decay curves follow the non-exponential decay in 273nm excitation and mono-exponential pathway for the 394 nm excitation.

Wastewater discharge is known to contain concoction of numerous toxic metals such as arsenic, cadmium, chromium, copper, lead, mercury, nickel, silver, and zinc. The presence of toxic heavy metals in water bodies can cause devastating effects on the environment and public health. Limitations in one form or the other in the present conventional methods has lead to the use of microbes and nanoparticle for the removal of pollutants from different environment system. The use of nanoparticles produced by a biogenic enzymatic process is far superior, in several ways, to those particles produced by chemical or physical process. The study reviews the application of bio-nanotechnology in the removal of toxic heavy metals from wastewater. This paper reviews the recent developments of the biosynthesis of nanoparticles and its mechanism; Remediation of environmental pollution through nanotechnology; Importance of nanotechnology in environmental management industry and its future prospect.

The risk of Hydrometeorological hazard post Covid- 19 pandemic Kriti, Geetgovind Sinam

Plant Ecology & Climate Change Science Division, CSIR-National Botanical Research Institute, Lucknow-226001 (India)


Every year many states of India are affected from flood during the monsoon season. Post covid-19 pandemic which first started from Wuhan city in China, every continent of the world are affected. India also reported its first case on 30 January, 2020, in the state of Kerala. Since then the number of infected persons is increasing. The detection of SARS-CoV-2 in sewage water of Netherlands is a serious risk hazard. Recently, the virus was also detected in the stools of severely infected persons from USA, France and Australia. In the event of COVID-19 pathogen from hospitals and quarantine centre’s reaching the sewerage, it would spread to the river it feed. In the advent of a flood during this period would cause mass spreading of the covid-19 pathogen to the people of India. The government of India in consultation with resource persons should strategize ways of monitoring and controlling the spread of covid-19 pathogens via wastewater discharge. Keywords: Covid-19, Flood, India, mass- infection, wastewater.

Synthesis, characterization and use of Phosphomolybdenum blue (PMB) in dual mode, colorimetric and spectrophotometric fluoride estimation in water samples

Debasish Ghosh

Chemical Division, Geological Survey of India, Shillong 793003, India email:

Phosphomolybdenum blue (PMB) test is well established for phosphate detection and estimation in water samples. We used this test for fluoride estimation and prepared solid phosphomolybdenum blue by a simple procedure. We attempted to detect fluoride due to its immense importance in waste water treatment, rock analysis, ground water analysis etc. WHO recommended maximum level of fluoride in drinking water is 1.5 ppm. Drinking of fluoride contaminated water over a long period of time may result in dental fluorosis and its effect becomes more severe as contamination level goes high. Consumption of heavily contaminated water may cause skeletal fluorosis. Ground water in some parts of the countries like India, China, Tanzania, Mexico, Argentina, and South Africa etc. is contaminated over WHO recommended maximum level. Thus detection and removal of fluoride from water is very important as per health concern. A number of very sensitive means for fluoride determination are available at present, e.g., ion selective fluoride electrode (ISE), photometric sensor, organic and inorganic sensors etc. Here we propose a simple rapid and cost effective dual mode colorimetric and spectrophotometric method for fluoride determination. In addition we tried to understand properties of the solid compounds, PMB and molybdenum oxide (MoO3) by different instrumental techniques like X-raydiffraction (XRD), infra-red (IR), UV-absorption, scanning electron microscope (SEM), transmission electron microscope (TEM), and photoluminescence. We found that PMB can detect up to 5 ppm F- in an aqueous medium and it has very good fluorescence property in solid phase. Light emitting property of PMB and MoO3 can be utilised in bio-imaging, light emitting diode (LED) etc.

**Delhi institute of pharmaceutical sciences and research NEW DELHI

Drugs have been developed and delivered to the patients by different delivery systems. Among the various dosage forms, tablets taken orally are considered to be the most convenient and stable unit dosages forms. But the geriatrics, bed ridden, psychotic’s patients, travelers and pediatrics find difficulty in swallowing the conventional dosages forms like tablets, capsules etc. Due to dysphasia this problems results in not taking the prescribed medication properly and have the efficacy of treatment being severely affected (Seager et al 1988). Being aware of these problems and to fulfill the medical needs, a segment of formulation better known by the phrase Orodispersible tablets (ODTS) has been developed by Dobetti et al 2001, Schiermeier et al 2002. The objective of the present study is to develop orodispersible tablets (ODTS) of buclizine HCl by using suitable polymer to meet the desired characteristics of ODTS and optimize the most appropriate formulation and across the optimized formulation for its in-vitro release profile consistently study is carried out to formulate and evaluate an orodispersible tablet of buclizine hydrochloride which disintegrates in mouth in contact with saliva in less than 60 seconds without intake of water. Buclizine, 1-(4-tert-butylbenzyl)-4(4-chlorobenzhydryl) is a piperazine derivative having antiemetic, antihistaminic, antimuscaranic, and selective properties used in motion sickness (British pharmacopoeia 2003), Martindale and Westcott, 1996, the Merck. Over the counter (OTC) and prescription medications are available such as dramamin (dimenhydranate), sturgerons(cinnarizine) ,antivert(meclizine), longifene(buclizine HCL) is effective. Dizziness fatigue, nausea are the most common symptoms of motion. Orodispersible tablets ( ODT) of Buclizine hydrochloride is made by direct compression method using compressible excipients such as microcrystalline cellulose (Avicel 102) aerosil and superdisintegrants crospovidone and crosscarmellose sodium, ) and other polymers. Superdisintegrants were used in different concentration. Evaluations were performed. As buclizine HCl is practically water insoluble did not show the good release of the drug. The release profile and bioavailability of buclizine HCl formulation was affected due to its poor solubility. So its solubility was increased by complexing it with betacyclodextrin. To the complex of Buclizine HCl and beta-cyclodextrin the optimized ratio of superdisintegrants and other suitable polymers are added Then its invitro release profile was studied and found good. Technique of direct compression of drug with compressible excipients like MCC , aerosol and superdisintegrant crospovidone ,crosscarmellose in different ratio were added to formulate the ODTs and give taste palatable and disintegrates in less than 30 seconds. All the excipients and API are compatible to each other. Comparision of dissolution profile of the optimized tablets (3%crospovidone ) and marketed product (Longifene). The optimized formulation shows the burst release at 5 mins whereas the marketed product shows its maximum release of 77.6%at 45 minutes. Hence it is to be taken 30 mins before travelling. Keywords: Orodispersible Tablets, direct compression method ,complexing ,betacyclodextrin , release profile. Superdisintegrant.

email: [email protected] Solanum khasianum C.B. Clarke (Solanaceae), is commonly known as Indian nightshade, Lam-khamen (Manipur).This plant is mainly distributed over the Khasi, Jaintia and the Naga Hills of Assam, Sikkim and Manipur. Traditionally, paste of unripe fruits of the plant is used for the treatment of swelling due to sprain, particularly leg muscles. The present study was undertaken to perform quality control standardization and to evaluate antioxidant activity in the aerial parts of Solanum khasianum. The various physicochemical parameters were evaluated using standard guidelines, such as moisture content, loss on drying, ash values extractive values, and phytochemical screening of the plant were evaluated. Further, quantitative estimations of different phytoconstituents such as total phenolic, flavonoid, tannin and alkaloid contents were carried out. Physicochemical parameters evaluated included ash values, extractive values, loss on drying. Phytochemical screening of different extracts and quantitative estimations revealed the extract to be rich in alklaloid (2.11% w/w) flavonoid (54.5 mg/g quercetine equivalent), phenols (62.75 mg/g gallic acid equivalent) and tannins (47.35 mg/g tannic acid equivalent). In vitro antioxidant studies depicted a potent antioxidant activity of extract that may be attributed to the presence of higher amount of alkaloids, flavonoids, phenols and tannins. The quality control standards obtained in the present study will provide referential information to researchers for proper identification and authentication of plant and will help in maintaining its pharmaceutical, botanical and economical importance. Keywords: Solanum khasianum, phytochemical standardization, total phenolic content, total flavonoid content, total tannin content, total alkaloid content.

Characterising Photoluminescence Spectra of Doped-YVO4 by using First Derivative

Sanoujam Dhiren Meetei Pettigrew College, Ukhrul, Manipur-795142, India


Photoluminescence (PL) spectroscopy is a powerful technique for characterisation of luminescent materials. This technique can investigate & measure excitation spectrum & emission spectrum, out of many parameters that can be studied with a PL spectrometer, to characterise a luminescent material. An emission spectrum is the intensity vs. wavelength distribution of an emission from a luminescent material measured at a single constant excitation wavelength, generally the wavelength corresponding to the maximum intensity of excitation. On the other hand, an excitation spectrum is the intensity vs. wavelength distribution of an excitation measured at a single constant emission wavelength, generally the wavelength corresponding to maximum intensity of emission. Both the emission and excitation spectra are not easy to characterise as these spectra are, generally, having multiple peaks embedded in a single spectrum, i.e., the spectra are convolute in nature. Therefore, many techniques are used for deconvolution of such spectra. And deconvolution of such spectra generally presume the peaks embedded in the spectra are of certain distribution (say, Gaussian). Here, in this work, excitation and emission spectra of samples: YVO4, Dy-doped YVO4 (henceforth YVO4:Dy) and Ca co-doped YVO4:Dy (henceforth YVO4:Dy/Ca) are recorded. The spectra are deconvoluted with a technique which does not require any presumed curve. That is, the spectra are deconvoluted by taking its first derivative. The process of deconvolution by this technique is simple as compared to other techniques. By using this technique, the PL spectra of YVO4, YVO4:Dy and YVO4:Dy/Ca are characterised to identify the multiple peaks embedded in their respective spectra. Then, energy levels corresponding to different peaks that were embedded in the spectra are identified. These energy levels are then employed to draw energy levels diagrams corresponding to the YVO4, YVO4:Dy and YVO4:Dy/Ca samples. Hence, the phenomenon of PL excitation and emission spectra observed from the samples are described on the basis of this technique based on its first derivative. Such technique will ease the way PL spectroscopy being used in characterisation of complex luminescent spectra and hence science & technology of luminescent materials.

Nuclear emulsion with its excellent spatial resolution and high efficiency for the detection of charged particles is observed for studies of high energy hadronic interactions. The analysis of the multiplicity distributions of secondary charged particles produced in interactions of cosmic ray nucleons in nuclear emulsion at high range of energy and compared with machine range of energy. It has been observed that the charged particle multiplicity and angular distributions in nucleon-Emulsion nuclei interactions can well be described by the hydrodynamical model. The distributions can be parametrised for the integral angular distributions.The signature for nuclear multiplicity scaling is also evident from the multiplicity distributions. The multiplicity ratio shows the non-dependence of target nucleus which implies the basic mechanism of particle production in both the nucleon-emulsion and nucleon nucleon interactions. KEY WORDS: Shower particle, Nuclear Emulsion, Pseudo-rapidity distributions, Integral angular distributions and multiplicity scaling.

Low-Dimensional Materials, especially materials confined into a box (zero dimension) had gained interest among the research community owing to its peculiar properties alien to its bulk parents. Carbon based dots, including graphene was not an exception to those peculiarity arising as a result of confinement. Unlike other (dimensionally) confined materials the properties of graphene quantum dots are edge influential. This report attempts to explain the formation of a new class of Graphene Oxide Quantum Dots based van der Waals Crystals, through a peculiar assembly achieved via a unique synthetic protocol, and the influence of its edges in the photoluminescent behavior of this ultra-small ~2nm dots. The works also shows how an introduction of different heterogenous atoms along the edges dictates the PL behavior of material, and thereby influencing almost the entire property of the dots.

Carbon nanomaterials have stood out over the years as one of the most versatile materials and attracted a lot of attention due to their encapsulation ability, controlled permeability, surface functionality, excellent chemical and thermal stability. The application and utility increases with higher surface area and better graphitization thereby increasing the electrical conductivity. In this work, we have explored the versatility of the hollow carbon nanospheres which were synthesized by a template-based method by subjecting to different modes of applications namely, encapsulation ability and catalytic properties. Graphitized hollow carbon nanospheres (gHCNS) with uniform size distribution and high amount of graphitization and nitrogen content were synthesized following a hard-templating method. A photocatalyst dye was encapsulated and the energy transfer was checked by analyzing the optical properties. The gHCNS is expected to provide stability and durability to such dyes by the protection of end groups and shielding off UV. The efficient confinement of dye inside the hollow core of gHCNS has greater implications of drug loading and delivery in biomedical applications. We also put into test the electrocatalytic property of the gHCNS and also modified it by incorporating Ni in a simple procedure which was introduced as a salt during the synthesis procedure of gHCNS. The modified Ni-gHCNS gave an overpotential value of 52 mV at 1.66 mg cm-2 loading at 10 mA cm-2 which was a great improvement over the bare gHCNS for hydrogen evolution reaction (HER).

It has been found that few studies have been reported on the determination of stability constants for binary and ternary complexes of some metal ions with different ligands by using Irving-Rossotti titration technique. Here, we have investigated the stability constants of copper(II) complex with (i) 1-amidino-O-methylurea (AMUH) as primary ligand and (ii) glycine (Gly) as secondary ligand at different temperatures (20 °C, 25 °C, 30 °C, 35 °C and 40 °C) with a fixed ionic strength of 0.5 M (KNO3) in aqueous solution. The pH-metric titration method of Calvin-Bjerrum as applied by Irving and Rossotti19 have been used for the determination of proton-ligand and metal-ligand stability constants. The study reveals the formation of 1:1:1 copper(II) complex. The values of overall changes in free energy ( ), enthalpy ( ) and entropy ( ) were evaluated. The existence of mixed ligand copper(II) complex has been analyzed by using isosbestic method spectrophotometrically at the wavelength of 600 nm and 700 nm respectively.

Department of Chemistry, Manipur University, Canchipur – 795 003, India e-mail: [email protected]

Excited state intramolecular proton transfer (ESIPT) is a phototautomerization where a proton is transferred through an intramolecular hydrogen bonded ring to an electronegative atom at a sub-picosecond time scale. Generally, ESIPT exhibiting molecules show dual fluorescence with the shorter wavelength emission called the normal emission and the longer wavelength emission called the tautomer emission.1 The ESIPT reaction and subsequently the photophysics of these molecules are greatly affected by the environment such as temperature, polarity, viscosity and mainly hydrogen bonding capacity of the solvent. In this presentation, the solvation study on the photophysics of 2-(2'-hydroxyphenyl)benzimidazole and its analogues (Chart 1) by employing polarizable continuum model (PCM) at the level of density functional theory is discussed.
