A Novel Approach to Processing of Australian Laterite Ores through Selective Reduction and Carbonylation. Processing of laterite ores, started in 1998 in Australia, has significantly enhanced Australian role on the international nickel market. However, the production of nickel from oxide ores by established technologies consumes two to three times energy as processing of sulphide ores with significant environmental impact. This underlines the importance of development of more energy efficient pr ....A Novel Approach to Processing of Australian Laterite Ores through Selective Reduction and Carbonylation. Processing of laterite ores, started in 1998 in Australia, has significantly enhanced Australian role on the international nickel market. However, the production of nickel from oxide ores by established technologies consumes two to three times energy as processing of sulphide ores with significant environmental impact. This underlines the importance of development of more energy efficient processes for oxide ores. The proposed technology will significantly decrease energy and water consumption, and greenhouse gas emissions in nickel production. It will enhance the competitiveness of Australian Nickel Industry and stimulate its expansion with significant economy and social benefits.Read moreRead less

The proposed program is aimed at studying numerous fundamental properties and phenomena of photoelectrochemical cells that have an important impact on environmentally friendly solutions to energy problems. Specifically, solar cells have a significant role in energy markets and in lessening CO2 emissions and other environmental impacts. Solar cell technology, coupled with renewable energy sources, has the potential to provide a long-term solution to the energy crisis and the global warming threat. In addition, the strong team to be assembled will reach a leading position in this area of cutting edge technology. The outcomes will benefit Australian industries.Read moreRead less
Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. ....Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. The significance lies in the ability to optimise reaction outcomes without the need for solvent screening. The innovation lies in the measurement of microscopic interactions between solvent and reagents, and the use of these interactions to affect a given process.Read moreRead less
Palaeobiology of hydrothermal mineral deposits. Mineral deposits that formed at up to 150 degrees C record the history of micro-organisms referred to as hyperthermophiles. Current biological studies predict that such organisms are the most primitive known. Thus by studying these deposits we have the opportunity to uncover the earliest history of life on Earth, and to improve our understanding of ore deposition. Such deposits are also prime targets for the search for life and former life elsewher ....Palaeobiology of hydrothermal mineral deposits.

Organic geochemistry of the McArthur River hydrothermal deposit. Exploration for hydrothermal ore deposits in sedimentary basins has many problems because of the lack of any general agreement on the mechanisms of formation of major deposits. This proposed research will focus on the fundamental issue of the interaction of organic matter and mineralizing fluids in contributing to ore mineral deposition. Given that the McArthur River orebody is an exquisitely preserved example of a hydrothermal dep ....Organic geochemistry of the McArthur River hydrothermal deposit. Exploration for hydrothermal ore deposits in sedimentary basins has many problems because of the lack of any general agreement on the mechanisms of formation of major deposits. This proposed research will focus on the fundamental issue of the interaction of organic matter and mineralizing fluids in contributing to ore mineral deposition. Given that the McArthur River orebody is an exquisitely preserved example of a hydrothermal deposit it will thus enable a comprehensive organic geochemical investigation to elucidate the role of organic matter in ore formation. The outcomes will benefit the Australian mineral exploration industry by refining current ore genesis models.Read moreRead less
Diamond genesis: cracking the code for deep-Earth processes. The project will provide new insights into the processes by which diamond crystallises in the Earth's mantle, and will deliver information directly relevant to interpreting the diamond prospectivity of the Australian continent. The development of a new diamond mine in Australia, or by Australian companies abroad, would be a major addition to the economy and Australian-based industry. Another outcome of this research will be further de ....Diamond genesis: cracking the code for deep-Earth processes. The project will provide new insights into the processes by which diamond crystallises in the Earth's mantle, and will deliver information directly relevant to interpreting the diamond prospectivity of the Australian continent. The development of a new diamond mine in Australia, or by Australian companies abroad, would be a major addition to the economy and Australian-based industry. Another outcome of this research will be further development of methodologies for identification of sources of individual diamonds, relevant to the international Kimberley Process for reducing theft and illegal diamond trade. The project will be a highly visible Australian contribution to this global social and economic problem.Read moreRead less
Isotopic fractionation in ore metals (Cu, Fe and Zn): A new window on ore-forming processes. Stable isotopes of common ore metals (e.g, copper and iron) are new tools for investigating ore deposits. Our data suggest that metal isotopic variations can provide new insights into mechanisms operative during formation of ore deposits. Stable metal isotopes also show promise as a new exploration tool for identifying the location of economic mineralisation within large prospective terrains; e.g., weakl ....Isotopic fractionation in ore metals (Cu, Fe and Zn): A new window on ore-forming processes. Stable isotopes of common ore metals (e.g, copper and iron) are new tools for investigating ore deposits. Our data suggest that metal isotopic variations can provide new insights into mechanisms operative during formation of ore deposits. Stable metal isotopes also show promise as a new exploration tool for identifying the location of economic mineralisation within large prospective terrains; e.g., weakly vs. strongly mineralised zones in a volcanic belt.
This project will provide fundamental baseline data that will help elucidate the processes that cause metal isotope variations. This will allow stable metal isotopes to be used much more effectively by the mining and exploration industries.

Cementitious gel: the missing link in understanding the ageing of built infrastructure. Exposure of built reinforced concrete infrastructure to coastal environments causes premature ageing, unplanned remediation and reduced safety. Enhanced forecasting, achieved by advanced methods, including Helium Ion Microscopy and modeling interactions between cement gel, chloride and water, will deliver proactive management of ageing assets.
Mathematical notation: a philosophical account. This project will explore philosophical issues associated with mathematical notation. In particular, it will provide an account of how mathematical notation is used in mathematical applications and how it facilitates analogical reasoning in science.
