Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will appl ....Hydrogeological drivers and fate of spring flow in a semi-arid setting. In arid and semi-arid climates, aquatic and terrestrial ecosystems often rely on groundwater springs. Spring hydrology depends on complex relationships between underlying aquifers and surface conditions, leading to high uncertainties in understanding aquifer-spring-wetland hydrology, which is critical for spring ecosystem protection and to inform management of relevant groundwater-affecting activities. This project will apply novel hydrogeophysical and hydrochemical methods, and computer modelling, to investigate the source aquifer of, and fate of discharge from the Doongmabulla Springs Complex (DSC), located in an area of future development. Project results will inform spring vulnerability to development pressures and climate effects.Read moreRead less
Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less
Extreme soil acidification and metal release risks from increasing drought. The project aims to study the effects of drought on pH and metal speciation in soils, and develop tools to assess current and future risks. Social and economic well-being depends on good soil and water quality. Climate change makes droughts more frequent and severe, which could cause soil acidification (pH<4) and metal release in many regions. The project will integrate experimental data on the effects of drought on soil ....Extreme soil acidification and metal release risks from increasing drought. The project aims to study the effects of drought on pH and metal speciation in soils, and develop tools to assess current and future risks. Social and economic well-being depends on good soil and water quality. Climate change makes droughts more frequent and severe, which could cause soil acidification (pH<4) and metal release in many regions. The project will integrate experimental data on the effects of drought on soil geochemistry with hydro-geochemical models, and apply these to national-scale predictions. The intended outcomes are improved management and preparedness for droughts and new research directions for geochemistry.Read moreRead less
Patchy colloidosomes at interfaces: correlation of particle surface heterogeneity, wettability, and chemical activity at the nanoscale. The surfaces of natural mineral particles are made up of spots with such different chemical and physical properties. The complexity makes it hard to predict their behaviour. This project will provide insights into how the 'patchy' nature of particle surfaces affects their behaviour in processes such as flotation separation and bio-fuel production.

Novel nanosensors for monitoring of water filtration membrane integrity. This project aims to develop arrays of electrochemical biosensors based on nanostructured silicon for real-time monitoring of water filtration membrane integrity. Real-time monitoring of membrane performance, based on removing virus-sized particles, is a priority for the water industry to maximise asset life and meet increased demand for safe and high-quality water. Materials scientists, electrochemists, and specialists in water management and reuse aim to harness advances in nanostructured transducers and electrochemical protocols to develop online performance-monitoring technology. This project is expected to improve water treatment processes, removing viruses and reducing the risks and uncertainties of water recycling.Read moreRead less
Closing the data gap: High throughput screening of nanoparticle toxicity. The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year.

The nanotechnology sector is experiencing an exponential growth period with over 100 products containing manufactured nanoparticles entering the market every year. Ensuring growth of the sector needs to be balanced against the imperative of protecting both human and environmental safety. This project aims to develop new methodological and conceptual avenues to close the gap between innovation in nanotechnology and risk assessment. This is intended to be achieved by developing and validating high-throughput in vitro toxicity screening platforms for manufactured nanoparticles. The approach is based on advanced lab-on-a-chip microfluidic technologies. The predictive power of the platform will be refined and optimised via ex-vivo and in-vivo models.Read moreRead less

Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high ....Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high quality long-term records are sparse and little investigated. This project will also underpin the outstanding universal value of the Fraser Island World Heritage Area which is based on the area being the world's largest sand island, but for which scientific understanding of the sand dunes is remarkably poor.Read moreRead less
