Electron Spin Resonance Spectroscopy (ESR), is a technique used to determine the presence of free unpaired electrons in a sample. Detection and life time studies of radical species is critical to understanding the mechanisms involved in chemical reaction, sample degradation, performance upon exposure to light and oxidation or reduction processes. Combining ESR with an electrochemical interface permits in-situ studies on how electrons are injected or removed from a sample, providing fundamental information on the processes occurring within the sample. Applications will be in the area of electrofunctional materials, complex biomolecular reactions, organic photovoltaics and new materials for nerve cell regeneration.Read moreRead less

An integrated electrolyser for CO2 conversion from capture media. This project aims to develop an efficient electrochemical method to convert carbon dioxide (CO2) to valuable chemicals. It expects to displace the energy-costly step of its upstream CO2 capture process. The key novelty is the use of flow-through electrodes and optimal solvents to promote CO2 conversion at high rates.

This project aims to develop an efficient electrochemical method to convert carbon dioxide (CO2) to valuable chemicals. It expects to displace the energy-costly step of its upstream CO2 capture process. The key novelty is the use of flow-through electrodes and optimal solvents to promote CO2 conversion at high rates. Expected outcomes include enhanced efficiency of CO2 sequestration, and new techniques to develop electrodes with well-controlled local reaction environments, which are essential for electrochemical energy conversion and storage. This will benefit Australia's environment and industries such as cement and aluminium manufacturing in managing carbon emissions, and accelerate Australia’s transition to a carbon-neutral economy.Read moreRead less
