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. Combining ESR with an electrochemical interface permits in-situ studies on how electrons are inje ....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. 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

The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous mater ....The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous material from the concentrate streams. This proposal will develop improved methods and techniques that will facilitate better, cleaner separations and recovery of the valuable oxide mineral components using Australian-developed flotation reagents.Read moreRead less
