The project aims to develop a new generation of miniature electrochemical devices based on ionic liquids, salts that are liquid at room temperature. In making these devices the project will study the fundamental physicochemical and electrochemical behaviour of the ionic liquid microinterfaces formed, and this will allow optimisation and enhancement of their properties. A gas sensor made of a micro-pattern of ionic liquid drops will be designed to detect gaseous toxic amines, which are released from numerous anthropogenic sources including waste water, sewage treatment, farms and industry. These sensors will be small, specific to the target gas, sensitive, fast in response and portable.Read moreRead less

Medium temperature electrolysis for low-cost carbon dioxide utilization. Carbon dioxide is a notorious greenhouse gas. Its capture, and subsequent storage or utilization, is a major focus not only for researchers, but also for governments trying to meet their obligations of the Paris Agreement on climate change and for industries managing their legal and social responsibilities.

Carbon dioxide is a notorious greenhouse gas. Its capture, and subsequent storage or utilization, is a major focus not only for researchers, but also for governments trying to meet their obligations of the Paris Agreement on climate change and for industries managing their legal and social responsibilities. This project aims to develop commercially viable medium temperature electrolysers to convert carbon dioxide into value added chemicals using electricity from renewable sources. New design principles will be developed to generate highly active and selective catalysts with long-term stability. These electrolyzers will be integrated with carbon capture technologies to directly utilize captured carbon dioxide with high energy efficiency.Read moreRead less
Electrostatic catalysis from single-molecule events to macroscopic systems. Electrostatics has important applications in day-to-day technologies, from recycling plastics to photocopying, but the exploration of how static charges affect chemical bonds and bonding is still in its infancy. This project aims to demonstrate the experimental links between the magnitude and polarity of an external electric field and chemical rates, expanding our understanding of chemical reactivity and transforming our ....Electrostatic catalysis from single-molecule events to macroscopic systems. Electrostatics has important applications in day-to-day technologies, from recycling plastics to photocopying, but the exploration of how static charges affect chemical bonds and bonding is still in its infancy. This project aims to demonstrate the experimental links between the magnitude and polarity of an external electric field and chemical rates, expanding our understanding of chemical reactivity and transforming our view of catalysis. By investigating the role of static electricity over systems selected from different sub-disciplines of chemistry, the project will derive the ground and selection rules for reactivity and selectivity by electrostatics. The project is expected to show that for chemical reactions of practical and conceptual value a specific catalyst can be replaced by a generic electric field stimulus, an invisible catalyst, enabling cleaner and cheaper opportunities that current technologies cannot fulfil.Read moreRead less

Summary
Interaction between silver ions, silver nanoparticles and reactive oxygen species: implication to toxicity. The project investigates the ability of various different (supported and stabilised) types of nanosized silver particles (SNPs) to oxidatively degrade selected contaminants and or kill microorganism. The project also aims to determine the effect of solution condition (for example pH) and light on SNP longevity and hence their oxidative capacity.

This project aims to build a physical-organic chemistry framework of transferable molecular descriptors for a relatively new but a rapidly developing area of unimolecular electronics (UE) using advanced computational chemistry tools. Established structure-property relationships will drive the cutting-edge applications of UE in sensing and catalysis and significantly expand our understanding of charge transport involving free radicals and non-covalent assemblies. Expected outcomes of this project include new design guidelines and candidate molecular architectures for such practical applications as organocatalysis inside molecular junctions, molecular spintronics and molecular sensors for reactive oxygen species and nitroaromatic pollutants.Read moreRead less
