Semiconductor spintronics is very likely to have a significant impact on future generations of devices. Until recently, Australian research groups have played a minor role in the field. The proposed program will lead to new discoveries or fundamental advances within semiconductor spintronics or have substantial impact on the progress in this field. The accomplishments of this project can greatly increase the scientific understanding of diluted magnetic semiconductors and expand Australia's knowledge base in research in these materials. This program can also be an education platform to provide a number of scientific talents for Australia by intensively training high quality postgraduates at the international level.Read moreRead less
Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less
Extending the range of the flotation process for particle separation. The minerals industry is a significant contributor to Australia's prosperity. Flotation is an important process for upgrading low-grade ores to high-grade concentrates, and for recovering fine coal from tailings. This project is aimed at solving a long-term problem in current flotation practice, the difficulty in recovering ultrafine and coarse particles, currently lost from production. We will pursue two new discoveries recen ....Extending the range of the flotation process for particle separation. The minerals industry is a significant contributor to Australia's prosperity. Flotation is an important process for upgrading low-grade ores to high-grade concentrates, and for recovering fine coal from tailings. This project is aimed at solving a long-term problem in current flotation practice, the difficulty in recovering ultrafine and coarse particles, currently lost from production. We will pursue two new discoveries recently made by us, relating to the recovery of ultrafines and coarse particles. Benefits to Australia are of the order of $500 million a year in increased exports, education of high-quality graduates, export income from license fees and equipment.Read moreRead less
Mass transport in aqueous foams. Flotation is extremely important in the minerals industry, whose exports are $110.5 billion annually. This project aims to significantly advance understanding of liquid transport in flotation froths, via a quantitative study of foam mass flow mechanisms. If successful, it may lead to modifications to current flotation devices, improving their froth-zone performance and saving money, water, energy and greenhouse gas emissions.
