Nanoscale Dynamics and Structure of SAILs at Electrodes. This project will produce new, high performance, surface active ionic liquids. Surface active ionic liquids are pure salts in which one of the ions is based on a surfactant molecule. Surface active ionic liquids are much more effective than conventional electrolytes for some applications, but only at elevated temperature; at low temperature, ion dynamics are too slow.

This project will produce new, high performance, surface active ionic liquids. Surface active ionic liquids are pure salts in which one of the ions is based on a surfactant molecule. Surface active ionic liquids are much more effective than conventional electrolytes for some applications, but only at elevated temperature; at low temperature, ion dynamics are too slow. We will use cutting edge techniques to probe ion dynamics in surface active ionic liquids in the bulk and at electrode surfaces, and use this to elucidate rules for the rational design of new surface active ionic liquids with fast dynamics at low temperature, towards their use at room temperature in diverse areas; this project will target capacitors and gas sensors.

Building bio-inspired smart nanochannels for virus detection. This project aims to harness high-precision silicon nanofabrication methods to create the next generation of bio-inspired viral biosensors. The new technology would enable prompt, cost-efficient, and accurate detection of virus contamination of our water and food supplies. The project plans to fabricate arrays of parallel double-layered nanochannels in silicon via templated etching, with surface functionalisation to display receptors. ....Building bio-inspired smart nanochannels for virus detection.

Summary
Shape sorting of nanoparticles at oil-water interfaces in microchannels. This project aims to study the effect of shape on the adsorption of nanoparticles at an oil/water interface and develop a rapid, inexpensive, efficient, versatile method for shape sorting of nanoparticles using a microfluidic approach. This technique can be applied for fractionation of synthetic nanoparticles, biosample analysis and environmental monitoring.
Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceu ....Characterisation of nanobubbles. Surprisingly, nano-sized bubbles have recently been found to exist in aqueous solutions. Classical theory tells us they should rapidly dissolve, yet they are stable for several days, a phenomenon which has only recently been explained. Despite this, nanobubbles are already used in cleaning processes and appear to have significant health benefits. They are being investigated in treatments for asthma and neurodegenerative diseases. In collaboration with a pharmaceutical company, the best means to produce and characterise nanobubbles will be investigated, as well as the conditions governing their stability. The project also aims to determine how the nanobubbles interact with surfaces in order to better control their properties and achieve a better understanding of these bubbles.Read moreRead less
Ionic lquids for scalable production of monolayer two-dimensional materials. This project aims to produce stable solutions of high quality, two-dimensional materials (2DMs, exemplified by graphene) in ionic liquids by spontaneous exfoliation. The project will develop processes for producing significant quantities of high quality 2DMs for use in a diverse range of technologies, and train graduate students in experimental and computational chemistry techniques.
Lab-on-a-chip mass spectrometry tools for testing illicit drugs. This project aims to develop fit-for-purpose mass spectrometry tools for roadside and workplace testing of illicit drugs. The technology will be based on nanostructured semiconductor chips that are surface-functionalised to enable molecular capture without extensive sample processing and subsequent detection by a novel combination of techniques. The technology is expected to be applicable to saliva, sweat and urine samples.
Photochemical and electrochemical control of redox enzyme cascades. Enzymes are the chemical factories of life. However, their use in industry and medicine is limited as it has been difficult to control enzymes outside the living cell. Here, we will develop a new groundbreaking approach for controlling enzymes, using light of different colours and electricity to switch different enzymes on or off on demand.
On-water electrochemistry: redox catalysis at the water surface. From plastics to pharamaceuticals, chemists rely extensively on expensive and environmentally damaging solvents and reactants. In water, greener and cheaper electricity-driven reactions currently suffer from low velocity and poor selectivity. The project aims to develop the science of on-water electrochemistry, to make electricity-driven organic reactions in water viable.

From plastics to pharamaceuticals, chemists rely extensively on expensive and environmentally damaging solvents and reactants. In water, greener and cheaper electricity-driven reactions currently suffer from low velocity and poor selectivity. The project aims to develop the science of on-water electrochemistry, to make electricity-driven organic reactions in water viable. Demonstrating that for electrochemical reactions, rates and selectivities increase on water’s surface rather than in its bulk will remove fundamental constraints on the viability of aqueous electro-synthesis – moving beyond current reactor designs to transform our view of electrochemistry and improve the sustainability of the chemical industry.Read moreRead less
