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

Electrolysis is a very widespread and efficient method of chemical synthesis both in industry and research. However, the link between the control voltage and the resultant current is often complicated and easily misinterpreted. To overcome this fundamental problem, we propose an optical spectro-electrochemistry instrument based on a two-dimensional CCD detection array. This radically new approach enables simultaneous spectroscopic and spatial data mapping in the realm adjacent to an electrode surface. Important applications range from unequivocal identification of elusive molecules to monitoring metal corrosion. Our first objective is to elucidate certain crucial transformations of mono- and binuclear heavy metal complexes.Read moreRead less
