Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

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.
