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

Multifunctional and environmentally friendly corrosion inhibitor systems. This project aims to design new, environmentally friendly coating systems for steel in marine environments by incorporating novel, non-toxic pigments that can be combined to protect against both corrosion and microbial attack.

This project aims to design new, environmentally friendly coating systems for steel in marine environments by incorporating novel, non-toxic pigments that can be combined to protect against both corrosion and microbial attack. Structural requirements for these compounds will be determined through the use of advanced characterisation techniques to identify the largely unknown mechanisms of attachment and protection on steel surfaces. The components may themselves be dual active, or be combined to capitalise on individual protection mechanisms that provide a synergy whereby the combination leads to better protection outcomes. Such coatings have the potential to significantly improve the lifetime of marine infrastructure.Read moreRead less

Degradation conscious grid-scale battery energy management scheme. The project aims to develop an improved battery management system to smooth the intermittent contribution of renewable energy sources to the grid. As the level of penetration of renewable energy sources into electrical grids increases, energy storage will play an increasingly important role in solving some of the technical challenges caused by the intermittent nature of the renewable sources.

The project aims to develop an improved battery management system to smooth the intermittent contribution of renewable energy sources to the grid. As the level of penetration of renewable energy sources into electrical grids increases, energy storage will play an increasingly important role in solving some of the technical challenges caused by the intermittent nature of the renewable sources. The existing design methods for grid-scale battery management systems do not take into consideration the degradation of the battery banks. Thus, this project aims to fill this gap by developing an electrochemical-based, degradation-conscious, battery management system. The proposed system aims to increase the life span and capacity use of the batteries.Read moreRead less

Previously the major means of dealing with per- and poly-fluoroalkyl substances (PFAS) is by adsorption, to collect and remove PFAS from contaminated sites. However, PFAS still exist, non-degraded and waiting for destruction. Targeting slurry waste from current remediation / adsorption plants, this project aims to efficiently degrade PFAS by combining electrochemical oxidation with sono-chemistry to enhance degradation capacity, to accelerate PFAS desorption / transportation from slurry waste, to avoid electrode fouling and to detoxify PFAS. The expected outcome of this project is to clean up contaminated sites, including PFAS / precursors and other persistent organic pollutants, leading to significant environmental benefits.Read moreRead less
