A number of new and emerging electrochemical device applications such as lithium batteries, dye-sensitized solar cells, electrochemical capacitors, actuators and bio-sensors are limited by their need for a liquid electrolyte. Many of these devices are considered vital to energy efficiency and the lowering of greenhouse gas emissions. The recent discovery of ambient temperature plastic crystalline electrolyte materials by the Monash Electrolytes group has raised the possibility of solving this problem. In this project new plastic crystalline electrolyte materials will be developed to suit these applications and their electrochemical properties investigated. Laboratory prototype devices will be prepared and tested and via collaborations with appropriate device developers, their performance evaluted.Read moreRead less

Summary
Electrochemical Electron Spin Resonance Spectrometer. 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.

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
