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 seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less
