New Nanoscale Up-converting Photoluminescent Materials for Passive Safety Visual Systems. The demand for safety and security products is growing as the importance of providing an environment safer from natural, accidental or man-made threats increases in the community. Life safety applications in buildings and work environments as well as trains and planes for example are dependent upon the ability for non-powered passive systems to give efficient visual guidance in dangerous dark and smoke fill ....New Nanoscale Up-converting Photoluminescent Materials for Passive Safety Visual Systems. The demand for safety and security products is growing as the importance of providing an environment safer from natural, accidental or man-made threats increases in the community. Life safety applications in buildings and work environments as well as trains and planes for example are dependent upon the ability for non-powered passive systems to give efficient visual guidance in dangerous dark and smoke filled environments. This project will provide a practical demonstration of the successful implementation of nanotechnology to smaller Australian companies where it will overcome significant drawbacks in current manufacturing and yield new products which are activated in darkness by infrared radiation.Read moreRead less
Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish ....Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish accurate and precise structures for the oxides, and distinguish both long range and short-range order which is critical to understanding both natural and synthetic U-oxides. This will help to define the geochemical conditions leading to the formation of deposits like Olympic Dam towards potential economic benefit.Read moreRead less
Urban biochar: towards prescriptive biochar use for maximum economic productivity and sustainability benefits in urban environments. This project will develop a life cycle assessment of waste management options for green waste and biosolids based on a clear understanding of productivity benefits of urban biochar application to high value production systems.
Harnessing renewable energy from low-carbon geothermal pavements. This project aims to investigate the extraction of renewable energy from new pavements constructed with low-carbon recycled demolition wastes. The proposed research will generate new knowledge on the thermo-geomechanical responses of pavements when harvesting heat energy under dynamic loads, using experimental and numerical approaches, including field trials. The outcomes and benefits will include strategic long-term collaboration ....Harnessing renewable energy from low-carbon geothermal pavements.

The proposed research will generate new knowledge on the thermo-geomechanical responses of pavements when harvesting heat energy under dynamic loads, using experimental and numerical approaches, including field trials. The outcomes and benefits will include strategic long-term collaboration with industry to develop ‘Geothermal Pavements’, with potential for commercial applications. The translation of this research will contribute to meeting future energy needs, while significantly reducing carbon emissions and diverting demolition wastes from landfills.Read moreRead less
Development and Testing of Novel Contrast Agents for Diagnostic Imaging. Demand for diagnostic imaging in the Australian healthcare system is growing at over 5% per annum. To facilitate imaging, Australia imports radiographic contrast media costing in excess of $50 million every year. Existing iodine-based agents are not ideal for X-ray absorption in current CT scanners and also cause moderate to severe allergic reaction in around 5% of all patients, sometimes with fatal results. New radiograph ....Development and Testing of Novel Contrast Agents for Diagnostic Imaging. Demand for diagnostic imaging in the Australian healthcare system is growing at over 5% per annum. To facilitate imaging, Australia imports radiographic contrast media costing in excess of $50 million every year. Existing iodine-based agents are not ideal for X-ray absorption in current CT scanners and also cause moderate to severe allergic reaction in around 5% of all patients, sometimes with fatal results. New radiographic media, which give enhanced contrast and provide greater patient comfort and safety are essential. Even a small fraction of the international market would generate millions of dollars in income, support growth and expertise in Imaging Technologies, and provide new markets for Australian mining of rare earth and bismuth metals.Read moreRead less
Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix ....Reinforced crumbed rubber concrete for residential construction. Reinforced crumbed rubber concrete for residential construction. This project aims to use crumb rubber from used tyres to replace natural sand aggregate in concrete used in housing construction. Globally, very few of the millions of tyres discarded annually are recycled, while natural sand used in concrete is being depleted. This project intends to provide the tyre industry with a viable market for end of life tyres, and the premix concrete industry with a “green” product for the residential construction market. Expected benefits include the increased use of a waste resource (used tyres), reduced use of a scarce natural resource (sand), and the development of an economic but green alternative concrete option for residential builders and owners.Read moreRead less
Effect of geopolymer cement stabilisation on the fatigue life of pavement sub-bases with recycled demolition aggregates. Road sub-base construction with demolition wastes using geopolymer stabilisation will be researched as Australian stockpiles of demolition wastes, such as concrete and bricks, are growing at 15 million tons per annum. Current sub-base design methods are intended for virgin materials, hence new research is required for waste materials in sub-bases.
Plastic deformation and failure of high strength rail steels in heavy haul transportation of mineral products. The Australian Government has made infrastructure, including rail, as a national priority for investment to meet the freight transport demand. This project focuses on the deformation and failure of rail in heavy haul lines to transport ores in the mining industry. The outcomes will be applied to ensure the structural integrity of rail infrastructure.
