UQ Summer Research Project Description – Chemical Engineering Project title: Air to Fuels – can direct air capture of CO2 help displace fossil fuels in transportation? Project duration: 10 weeks – Nov 25, 2019 to Feb 14, 2020 (2 weeks break at Christmas/New Year) Description: As the world begins to take action on climate change, the transportation sector looms as one of the largest and most challenging transformations. There are two main pathways decarbonisation of this sector may be achieved. The first is electrification of transport and the decarbonisation of the electricity sector.

Project title: Air to Fuels – can direct air capture of CO2 help displace fossil fuels in transportation?

Project duration: 10 weeks – Nov 25, 2019 to Feb 14, 2020 (2 weeks break at Christmas/New Year)

Description: As the world begins to take action on climate change, the transportation sector looms as one of the largest and most challenging transformations. There are two main pathways decarbonisation of this sector may be achieved. The first is electrification of transport and the decarbonisation of the electricity sector.

Direct capture of CO2 from the ambient air has been proposed as a means of reducing the CO2 concentration in the atmosphere and thereby reducing the main driver for climate change. However, the question remains - what to do with the CO2 once it is captured. Geological sequestration is frequently touted as an option and whilst effective has geological limitation and societal roadblocks in a number of regions. Recycling the CO2 to fuel and in the process displacing crude oil has the potential to deliver carbon neutral transportation. Such a process may utilise low carbon electricity to make H2 which is then combined with CO2 from the air to produce liquid or gaseous fuels which are readily substituted into existing technologies.

This process will evaluate air to fuels technologies with a variety of fuels as the final product. The project will be desktop based, using Aspen or Hysys to do the process flow sheeting.

UQ Summer Research Project Description - Chemical Engineering

Project title: Electrochemical oxidation of fluorinated pollutants in groundwater using perovskite type

catalyst Project duration:

10 weeks

Description: Long term usage of fluorinated compounds in various industrial and domestic application has led to a slow but steady release of such chemicals into the environment and resulting in polluting the soil and groundwater. While the concentration of such pollutants are low but due to their persistent nature, they tend to remain and accumulate in the ecosystem over a very long duration. Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are an excellent example of such pollutants. They have been widely used in industrial and commercial areas for more than half century, such as textile industries, semiconductor, metal plating, and so on. PFOS and PFOA have now been frequently detected in groundwater sample in various parts of Australia and are potentially harmful to human health.

Advance oxidation processes (AOP) can be an effective method to destroy persistent or toxic pollutants. In case of persistent pollutants the technology is used to partially break down the chemicals to simpler molecules which are then susceptible for biodegradation e.g. in a typical wastewater treatment plant. However, in case of PFOS/PFOA, the primary requirement is de-fluorination of the pollutant species followed by stabilising the fluorine into a benign species. Because of a high electronegativity and a small size of the fluorine atom, the carbon-fluorine bonds are the strongest bonds in organic chemistry and hence the bond dissociation cannot easily occur without considerable energy expense. Furthermore, the stabilization of fluorine requires a strong reducing a reducing agent seldom found in conventional AOP. In this project, we design the novel perovskite as a highly active and durable electro-catalyst that can help to achieve simultaneous oxidation-reduction reaction to facilitate the destruction and mineralization of PFOS and PFOA. The experimental investigation will include the synthesis of the catalyst and testing its efficiency for the destruction of PFOS/PFOA pollutants using a batch reactor. Additionally, the study will also investigate the rate of reaction including the effect of temperature, pH and concentration on the reaction kinetics.

Expected outcomes and deliverables:

The experimental program will provide training in basic laboratory skills and conductingbatch experiments.

Students will get to learn and operate state of the art analytical instrument for measuringlow concentration of pollutants in groundwater

Students will gain skills in data collection, understating and interpreting results generatedfrom analytical instruments.

Have an opportunity to generate publications from their research or present in a conference.Suitable for: UQ enrolled students only.

Candidates with a background in chemical engineering, chemistry or materials science. 3rd or 4th year Bachelor degree students or master students. Student who will extend this vacation work research later as part of individual inquiry &

UQ Summer Research Project Description – Chemical Engineering

Project title: Ionic Liquids as a “Green” Lubricant Additive

Project duration: 10 weeks

Description: Lubrication plays a pivotal role in sustainability and performance of energy efficient and durable mechanical systems, which includes those utilised in renewable energy such as wind turbines. Some current additives in lubricants have long-term toxicity concerns and produce undesirable side-product compounds. This project focuses on ionic liquids (IL), which are emerging as an entire new class of so-called “green” lubricants. The benefit of IL is that they can be “tuned” using different types of anions and cations, and thus designed to act as the lubricant or as an additive to oil. A technical barrier as an additive is designing them to be miscible in nonpolar oils, such as polyalphaolefin (PAO).

The aim of this project is to design and evaluate environmentally-friendly oil-miscible ILs as oil additives and compares to standard formulations. This will involve fabrication of ILs and measurement of rheology, friction and wear using state-of-the-art facilities.

Expected outcomes and deliverables:

Students may gain knowledge/skill in concepts/measurement of rheology and tribology, general data collection and analysis techniques. A written report and an oral presentation are required at the end of the project.

Results from this project may contribute or partly contribute to a publication. Therefore, there may be an opportunity of an authorship or co-authorship of a general paper. Student will attend weekly meetings with Prof Jason Stokes’ group

Suitable for: This project requires a chemistry and engineering background as it requires both synthesis and characterization methods. Students with a background in chemical engineering/chemistry at either 3rd or 4th year are desirable.

UQ Summer Research Project Description – Chemical Engineering

Project title: Responsiveness of viscoelastic biological surface films Project duration: 10 weeks

Description: It is known that adsorption of proteins or polysaccharides to soft surfaces improves lubrication, as measured using soft contact tribology, and the film thickness, measured using Quartz crystal microbalance with Dissipation (QCM-D). This adsorption has been shown to be relevant to the sensory mouthfeel of foods and beverages. The majority of existing literature measuring tribology of the food components and its relationship to adsorbed film thickness has been carried out in the absence of Human whole saliva (HWS), yet we know that saliva plays a key role in the sensory perception of foods.

The aim of this project is to investigate the influence of food components and mixtures on the salivary film thickness and adsorption, desorption and hydration of saliva and food-saliva composite films.

The student will utilise the Quartz crystal microbalance with Dissipation (QCM-D) to study how dairy and meat proteins, polysaccharides and solvent quality, influence the viscoelasticity, hydration, structure, and lubricity of pre-adsorbed saliva-films.

Expected outcomes and deliverables:

The student will be given the opportunity to gain experience and in-depth understanding of soft contact tribology, rheology and measurement of thin films using Quartz-crystal microbalance with dissipation. (QCM-D)

It is anticipated that the student’s findings will generate a publication or part thereof. Students will be expected to produce a report and oral presentation at the end of their project. Student will attend weekly meetings with Prof Jason Stokes’ group

Suitable for: This project is open to applications from 2nd -4th year students with a background in, materials engineering, chemistry, or chemical engineering who have completed all compulsory requirements for their current year of study.

Project title: Rheology properties of casein micelles at neutral condition

Project duration: 10 weeks

Description: Milk proteins are the key ingredient in a vast range of nutritionally rich foods and beverages. A key challenge is having utmost control over protein functionality to form structures and control texture and mouthfeel. Milk proteins consist of around 80% casein, with 95% of these in the form of so-called casein micelles that are a large aggregated colloid. While there is considerable literature examining the properties of aggregated casein micelles at low pH when forming gels (e.g. yogurt), there has been limited investigations under neutral conditions. Here we aim to examine the rheology of casein micelles at neutral conditions in the presence of different ions, e.g. calcium, phosphate. The knowledge gained will be utilised within a research partnership with a major international dairy company.

Expected outcomes and deliverables:

Students will gain an insight into industrial research. Students may gain knowledge/skill in concepts/measurement of rheology and tribology, general data collection and analysis techniques. A written report and an oral presentation are required at the end of the project. Results from this project may contribute or partly contribute to a publication. Therefore, there may be an opportunity of an authorship or co-authorship of a general paper. Student will attend weekly meetings with Prof Jason Stokes’ group.

Project title: Solidification of oxide meltsProject duration: 10 weeks

Description: Slags are now treated by industry as important by-products of metallurgical operations rather than waste materials. The applications include raw materials for Portland cement and construction materials. Slags are treated to recover dissolved or entrained minor elements. The solidification of oxide melts from metallurgical melts is becoming a more important topic as the focus on sustainability and environmental impact is increasing.

Key to the physical and chemical properties of these oxide materials are the phases and microstructures formed on solidification. Whilst the solidification of metal alloys is a cornerstone of many metal processing technologies in comparison, the topic of oxide solidification has received relatively little attention.

The Pyrometallurgy Innovation Centre (PYROSEARCH) has developed new expperimental techniques to enable controlled cooling of these melts and the examination of the phases and microstructures formed at each stage. The project will build on existing research and provide new experimental data on a range of slag compositions and solidification conditions.

Expected outcomes and deliverables:

Student will work with an existing research team, obtain practical experience in high temperature laboratory based research, and is expected to produce a professional quality report and oral presentation at the end of their project.

Project title: Structural characterization of FeO-Fe2O3-SiO2 liquid slags using Raman spectra and their relationship with viscous behaviours

Project duration: 10 weeks

Description: This project aims to investigate the structures of FeO-Fe2O3-SiO2 liquid slags through the glass phase, and the relationship between structures and the properties of slags, namely, viscous behaviours. It is believed that the macro properties of the slags are determined by their microstructures. Therefore, clarifying the microstructures of slags will be able to predict their properties. Moreover, the modification of slags properties for industrial purposes can also be deepened into the microstructural level. FeO-Fe2O3-SiO2 is a basic system in many industrial processes and natural system. Accurate viscosities of the slags have been measured at high temperature and Raman spectra have been obtained from the glass. The present project will analyse the available data to understand the micro-macro relationship of this slag system.

Expected outcomes and deliverables:

The experiments have been performed using the research technique developed at UQ where the experimental conditions are accurately controlled. The chemical compositions of the slags after quenching have been analysed using the EPMA. The microstructures of the quenched slags have been measured using the Raman spectra the viscosities of the slags have been measured and will also be predicted using the FactSage software. The FeO/Fe2O3 ratio in the slags will be obtained from FactSage. A report is expected at the end of the project and a publication may be produced from the results.

Suitable for: This project is suitable for the students from relevant majors in engineering who have completed at least two years undergraduate study.

UQ Summer Research Project Description – Chemical Engineering

Project title: Synthesis of adsorption materials from clay minerals Project duration: 10 weeks

Description: Currently, most clay minerals in the mining tailings or low-quality clay ores is perceived as the waste due to high-cost process and limited market. Recently, we have developed a sustainable way with low cost to utilise these clay minerals. By manipulating kinetics and crystallization process, various types of zeolite-like adsorption materials can be synthesized which can be used as high-performance absorbents for the heavy metal removal in the aqueous/soil environment. This project followed on the previous research project on synthesis of zeolites from low grading bauxite or kaolin for heavy metal removal. In this study, we will extend the investigation on utilising different clay minerals. We aims to conduct proof-of -concept study on synthesis the various types of zeolites from different feeding source. Then, these zeolites will be tested for different applications such as ethanol dehydration and gas separation and ion exchange et al. This project is supported by pathfinder fund from UniQuest.

Expected outcomes and deliverables:

The student will gain skills in experimental skills in sample sintering and alkaline leaching. There will likely be liquid and solid sample characterisation by ICP, XRD and SEM. The student will present project outcomes to the hydrometallurgy research group. The deliverable will be a functioning mass and energy balance model for the process and outcomes of the sensitivity analysis.

Suitable for: This project is most suited to metallurgical/chemical/environmental engineering students with an interest in the environmental engineering and product synthesis.

Project title: Using low-cost adsorbents for separating fluorinated pollutants from groundwater Project duration:

10 weeks

Description: Long term usage of fluorinated compounds in various industrial and domestic application has led to a slow but steady release of such chemicals into the environment and resulting in polluting the soil and groundwater. While the concentration of such pollutants are low but due to their persistent nature, they tend to remain and accumulate in the ecosystem over a very long duration. Perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) are an excellent example of such pollutants. They have been widely used in industrial and commercial areas for more than half century, such as textile industries, semiconductor, metal plating, and so on. PFOS and PFOA have now been frequently detected in groundwater sample in various parts of Australia and are potentially harmful to human health. The conventional techniques of water and waste-water treatment including biological degradation, oxidation and reduction have failed to destruct PFOS in ambient environments due to their stability and persistent nature. The adsorption technology has been found to be a promising method to separate PFOS and PFOA from water and is currently used as a commercial technique for groundwater remediation. However, the commercial adsorbents such as activated carbon or resins are expensive and difficult to regenerate. As these adsorbents gets saturated, they are dumped into landfills thus making the remediation process economically unfavourable. In this project, we propose to use the low-cost adsorbents, such as bentonite and fly ash for PFOS and PFOA removal from groundwater. Apart from being significantly cheaper than commercial activated carbon and resins, these adsorbents are abundantly available. The experimental investigation will include measuring the adsorption capacity of PFOS and PFOA pollutants on the selected adsorbents and comparing their capacity with the commercially available adsorbent materials. Additionally, the study will also investigate the rate of adsorption including the effect of temperature, pH and loading on the adsorption kinetics.

Expected outcomes and deliverables:

• The experimental program will provide training in basic laboratory skills and conducting batch experiments.

• Students will get to learn and operate state of the art analytical instrument for measuring low concentration of pollutants in groundwater

• Students will gain skills in data collection, understating and interpreting results generated from analytical instruments.

• Have an opportunity to generate publications from their research or present in a conference

Suitable for: • UQ enrolled students only.• Candidates with a background in chemical engineering, chemistry or materials science.• 3rd or 4th year Bachelor degree students or master students.• Student who will extend this vacation work research later as part of individual inquiry &

UQ Summer Research Project Description – Chemical Engineering

Project title: Viscoelastic Lubrication

Project duration: 10 weeks

Description: Lubrication is critical for functionalities of many biological systems including mussel, joint and tongue. The relative sliding motion between two viscoelastic substrates is often encountered in those systems, at which surfaces deform during the sliding. Sliding between viscoelastic substrates causes a dynamic entrainment and confinement of fluid lubricant at interfaces, as such properties of lubricant fundamentally determine the overall lubrication behaviour. Lubricants involved in most biological systems are complex fluids or soft matters with non-Newtonian behaviours and viscoelasticity, which makes it challenging to characterise the lubrication between viscoelastic contacts.

The aim of this project is to collectively characterise the interface friction and mechanics (termed ‘tribology’) and fluid/soft matter mechanics (termed ‘rheology’), from which it is deemed to form a correlation between frictional behaviour and fluid rheology. Specifically, the student will measure the tribology between soft contacts using a range of lubricants, and will be encouraged to further investigate the effect of lubricant rheology on the overall frictional behaviour. Student will document a literature review and conduct experimental works under supervision of a senior lab user. Experimental work including rheology and tribology measurement will be completed in “Rheology, Tribology and Biointerfaces Laboratory”, led by Professor Jason Stokes.

Expected outcomes and deliverables:

Students may gain knowledge/skill in concepts/measurement of rheology and tribology, general data collection and analysis techniques. A written report and an oral presentation are required at the end of the project. Results from this project may contribute or partly contribute to a publication. Therefore, there may be an opportunity of an authorship or co-authorship of a general paper. Student will attend weekly meetings with Prof Jason Stokes’ group

Suitable for: This project is suitable for 2nd to 4th year undergraduate student or course work post-graduate student majoring in Chemical Engineering or its varieties. It is expected that undergraduate applicants have finished all compulsory courses listed for their program up to the year of their study.

Project title: Viscoelastic Polyelectrolyte Multilayers Project duration: 10 weeks

Description: Polyelectrolyte Multilayers (PEM) are currently seeing a resurgence in scholarly interest for the purposes of understanding the contribution of surface films to tribological phenomena and performance (friction, lubrication and wear). To provide insight at the nanoscale, an Atomic Force Microscope (AFM) is typically implemented.

Unfortunately, despite the wealth of publications produced in the past decade (owing to their popularity in biomedical applications), most papers fail to comprehensively investigate and present all tribologically significant properties at the nanoscale when varying fabrication parameters. As such, it is necessary that a comprehensive analysis is performed to understand the impact of fabrication parameters and enable fine tunability of PEM for nano-tribological applications.

This project intends to investigate the complex interplay and sensitivity involved in the systematic variation of solvent quality and cross-linking density on the growth and tribo-mechanical properties of PEMs. In particular, the viscoelastic behaviour, interfacial adhesion, roughness and wettability will be evaluated at the sub-asperity scale using AFM and the Quartz Crystal Microbalance with dissipation monitoring (QCM-D). These properties are then to be evaluated at the macroscale using a mini-traction machine (MTM) tribometer.

Expected outcomes and deliverables:

The student will be given the opportunity to gain experience and in-depth understanding of both nanoscale and macroscale soft contact tribology and rheology.

It is anticipated that the student’s findings will generate a publication or part thereof. Students will be expected to produce a report and oral presentation at the end of their project. Student will attend weekly meetings with Prof Jason Stokes’ group

Suitable for: Applications from 3rd -4th year students are preferred with a background in mechanical engineering, materials engineering, chemical engineering or physics. It is expected that the student is competent with MATLAB.

Project duration: 10 weeks

Description: The issue of treatment of end-of-life manufactured devices is becoming increasingly important as the volume of these materials continues to increase. These devices contain valuable metals such as gold, silver, platinum group metals, and rare earth elements. In addition, they typically contain >20 other elements. The race is on to identify more efficient ways to treat these complex materials. The large number of different elements and the dispersion of the elements between small components makes smelting an attractive option for processing Currently, the recycling of waste electric and electronic equipment (WEEE) in primary copper production is done mainly to recover noble metals. However, most successful electronics recyclers, such as Umicore (Belgium) and Boliden (Sweden), use integrated primary copper, secondary copper, primary lead and secondary lead smelting, and hydrometallurgical treatment. Recycled products can enter the process at different stages depending on the type of material. Through the optimization of process conditions in every smelting unit and by redirecting internal streams, the whole plant can achieve higher utilization of energy and production of valuable goods. For an integrated plant, the main source of losses of valuable metals is discarded slag from smelting stage and from slag blow converting stage. The Pyrometallurgy Innovation Centre (PYROSEARCH) has developed new experimental techniques to enable the chemical equilibria and elemental distributions in multi-phase systems to be accurately measured. The project will build on existing research and provide new experimental data on a range of slag compositions and will complement existing research on this topics currently being undertaken at the Centre. ://pyrosearch.chemeng.uq.edu.au

Project title: Pyrometallurgical production of lithium ion battery materials

Project duration: 10 weeks

Description: The transition to the e-economy which is happening now includes the increasing deployment of electric vehicles (EVs), which will be principally be powered from lithium ion batteries. The positive electrode (cathode) in these batteries consists of mixed transition-metal oxides, one class of materials has a general chemical formula LiNiwMnyCozO2 (w + y + z = 1). These materials can be viewed as LiCoO2-LiNiO2-LiMnO2 solid solution phase. The power, durability, cost and discharge characteristics of the batteries depends critically on the composition of the cathode material. The range and complexity of the compositions and structures formed means that it is difficult to select the optimum composition for different applications of the materials. Fundamental research on the thermodynamic properties of these cathode materials is being undertaken at the UQ Pyrometallurgy Innovation Centre, (PYROSEARCH ), School of Chemical Engineering to assist in understanding the behaviour and potential properties of these materials. PYROSEARCH has developed new experimental techniques to enable the chemical equilibria and elemental distributions in multi-phase systems to be accurately measured. The project will build on existing research and provide new experimental data to complement existing research on this topics currently being undertaken at the Centre. ://pyrosearch.chemeng.uq.edu.au

UQ Summer Research Project Description – Chemical Engineering

Project title: Investigating human vascular ageing with iPSC-derived perivascular cells and microfabricated, 3D bioprinted devices

Project duration: 10 weeks

Description: Enabling the aged to remain active, productive and participatory within society represents one of Australia’s greatest challenges in the next 50 years. To develop novel solutions to extending health span as our population ages, it is essential to understand the biology of ageing and the fundamental mechanisms underlying the reduced capacity to maintain functional tissue as we age. Tissue homeostasis is supported throughout our lives by resident stem cells in all of our tissues, which are ‘housed’ within the perivascular niche. Dysfunction of the perivascular niche is considered as a major impactor in the bulk of age-associated loss in tissue function and is specifically associated with many age-related vascular diseases, such as arteriosclerosis. Whilst animal models of human vascular diseases exist, their utility as therapeutic screens is always in question. Ideally, we need human models of vascular ageing and dysfunction in the lab so that we can understand the cellular and environmental drivers of human vascular ageing, and ultimately screen therapeutics for their ability to recover lost function. This project will construct microvessels (the basis of the perivascular niche) from human induced pluripotent stem cell-derived endothelial cells and pericytes within hydrogels in microfabricated (3d bioprinted) perfusable devices. Functional changes in vessel mechanics and ability to support angiogenesis will be assessed. These iPSC-derived cell types will then be induced to ‘age’ in the device through the expression of age-related proteins that affect mechanotransduction and the ability of cells to adapt to mechanical stresses imposed on them during perfusion.

Expected outcomes and deliverables:

The development of a novel model of a human ‘perivascular niche in a dish’ and the validation of the model to provide insight into changes in vascular function with the induction of ageing proteins in each cellular compartment. Proof-of-concept of this model as a screening platform for the discovery of new drugs to rejuvenate aged blood vessels.

Suitable for: 3rd – 5th year in the following degree programs: Chemical and Biological Engineering, Biomedical Science.
