The depletion of oil reserves and the effects of global warming make the development of new, clean, sustainable fuel production systems critically important. This frontier technology has the ability to drive solar-powered hydrogen production from water. Extending the system to marine algal cells provides the possibility of coupling clean fuel production with water purification as the product of H2 combustion is pure water. We have already engineered green algae that produce H2 from H2O at a rate ~1000% higher than the Wild-type and through this project will incorporate further improvements with the aim of developing a competitive H2 production system.Read moreRead less
Novel nitrogen removal process via nitrite in a biofilm system and analysis of microbial community dynamics. Nitrogen removal from wastewater is essential to protect our unique aquatic environment. This removal is typically achieved via two steps: Nitrification converts ammonium via nitrite to nitrate; denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project will develop a biofilm reactor system, which enables this process to run via nitrite only, instead of nitr ....Novel nitrogen removal process via nitrite in a biofilm system and analysis of microbial community dynamics. Nitrogen removal from wastewater is essential to protect our unique aquatic environment. This removal is typically achieved via two steps: Nitrification converts ammonium via nitrite to nitrate; denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project will develop a biofilm reactor system, which enables this process to run via nitrite only, instead of nitrate. Savings of 40% carbon and 25% oxygen requirements are possible this way. This process has not yet been demonstrated under controlled conditions, but recent progress in the research groups in Australia and Korea now offer novel ways to accomplish this promising process.Read moreRead less

These highly-order crystalline structures are genetically-encoded and produce high-performance composite materials that exceed present capabilities in human engineering. This international collaboration will elucidate the molecular mechanisms controlling the fabrication of these architectures. This knowledge will contribute significantly to the development of materials for advanced electronics and energy transducers, human bone therapeutics and marine-based products such as pearls and cements, through the identification of genes underlying biofabrication networks and the development of in vitro bioproduction systems.Read moreRead less
Determining global and regional conservation priorities for biodiversity hotspots. The economic wealth of both Australia and Israel is underpinned by biological diversity - for example the remarkable biological diversity of both countries fuels multimillion-dollar tourism industries. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity 'hotspots' of the Mediterranean ecosystems of the world. We will create and test new theory and to ....Determining global and regional conservation priorities for biodiversity hotspots. The economic wealth of both Australia and Israel is underpinned by biological diversity - for example the remarkable biological diversity of both countries fuels multimillion-dollar tourism industries. We will devise methods to make better decisions about where to invest conservation dollars amongst the biodiversity 'hotspots' of the Mediterranean ecosystems of the world. We will create and test new theory and tools for incorporating into decision making the effect of processes such as climate change and invasion by alien species, which will help reduce the huge detrimental impacts on social, economic, health and human-well being. We will share the results of our work with decision makers and with the public.Read moreRead less

Beach groundwater is a highly complex, dynamic system interacting with tides, waves and swash. Such interactions affect beach sediment movement and contaminant transport/transformation in coastal aquifers. This project aims to measure and model the groundwater's behaviour at three different types of beaches: sand, gravel and gravel-sand mixed beaches. The study will provide much needed understanding and quantification of the beach groundwater dynamics over a range of time scales. The outcome will help to assess the extent and intensity of mass and momentum exchanges across the beach face, and the resulting effects on beach stability and the fate of contaminants in coastal aquifers.Read moreRead less

Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits ....Drying sewage sludge using hot oil. The project seeks to investigate and develop an entirely new area of fundamental and applied research involving the process, mechanisms and kinetics of direct dehydration of sewage sludge by fry-drying in hot oil. Frying can be carried out as a drying process, though it not widely recognized or applied in this way, and has consequently not been exploited outside of the traditional food industries. It potentially provides a wide range of significant benefits for sludge drying, including high efficiency and low costs, and produces a non-offensive product with a high energy value suitable for (renewable) power generation.Read moreRead less
Weathering History and Cenozoic Landscape Evolution in Northern Queensland and New Caledonia. Rates of rock weathering impose a major control on the CO2 global budget. Increased weathering rates consume atmospheric CO2, possibly resulting in cooler climates. We intend to determine rock weathering rates on similar lithologies currently placed on equatorial positions, Northeastern Australia and New Caledonia, but possibly differing in climatic history. Geochronology of continental weathering prof ....Weathering History and Cenozoic Landscape Evolution in Northern Queensland and New Caledonia. Rates of rock weathering impose a major control on the CO2 global budget. Increased weathering rates consume atmospheric CO2, possibly resulting in cooler climates. We intend to determine rock weathering rates on similar lithologies currently placed on equatorial positions, Northeastern Australia and New Caledonia, but possibly differing in climatic history. Geochronology of continental weathering profiles in the areas will permit correlating known paleoclimatic cycles, derived from the isotopic composition of ocean floor sediments, with the variation in continental weathering rates. This comparison will test current models proposing that cooling of Cenozoic climates results from increase rates of rock weathering.Read moreRead less
International interventions: ethical, legal and political issues. The project is the first stage of a larger study in partnership with Canadian researchers. The pilot will develop case studies showing the political, ethical and legal issues currently influencing intervention within other States for peacekeeping, peacemaking or humanitarian reasons.

The pilot will develop case studies showing the political, ethical and legal issues currently influencing intervention within other States for peacekeeping, peacemaking or humanitarian reasons. There is currently no internationally agreed legal, ethical or political code underlying such decisions to intervene. Humanitarian disasters are likely to increase with the proliferation of new states and re-emergence of ethnic and religious intolerance. Australia's defence policy recognises that peacekeeping is a significant function for our armed forces. Australia should influence thinking on when the international community should act.Read moreRead less
