Reactive oxygen species generation by zerovalent silver nanoparticles; implications to toxicity and contaminant degradation. Nanoparticulate silver is now being used for the purification of drinking water yet many questions remain concerning its mode of purifying action. Here we investigate the generation of reactive oxygen species (ROS) by nanoparticulate silver and examine the relationship between ROS generation and the purifying action of "nano-silver".
Measuring the impact of urban regulation on housing affordability in Australian cities and regions. Urban planning must ensure that development meets new environmental goals, but stringent regulation may reduce housing supply and affordability. This project uses new local planning data and econometric studies to quantify and monitor planning regulation impacts on housing supply and affordability in Australian cities and regions.
Shadow care infrastructures: sustaining life in the post-welfare city. Mounting evidence points to difficulties faced by Australians reliant on government income support in meeting market costs of essential needs. This project investigates whether and how ‘shadow care infrastructures’ – a wide range of formal and informal material and social supports – enable the survival, well-being and flourishing of income support recipients. Focusing on people with disabilities, unemployed and asylum seekers ....Shadow care infrastructures: sustaining life in the post-welfare city. Mounting evidence points to difficulties faced by Australians reliant on government income support in meeting market costs of essential needs. This project investigates whether and how ‘shadow care infrastructures’ – a wide range of formal and informal material and social supports – enable the survival, well-being and flourishing of income support recipients. Focusing on people with disabilities, unemployed and asylum seekers, the study evaluates the benefits and harms such infrastructures produce for those receiving and providing care, and the wider community. It examines risks and opportunities to scale up emerging care infrastructures identified as critical to making ends meet for income support recipients in contemporary cities.Read moreRead less
Reactive oxygen species production on oxygenation of subsurface sediments. This project aims to examine the nature, extent and effect of redox processes in subsurface environments. Reactive oxygen species, including hydrogen peroxide, superoxide and hydroxyl radicals, transform and affect redox-active substances in the environment such as arsenic, uranium and natural organic matter (which may be oxidised to carbon dioxide). Production of significant quantities of reactive oxygen species on oxyge ....Reactive oxygen species production on oxygenation of subsurface sediments. This project aims to examine the nature, extent and effect of redox processes in subsurface environments. Reactive oxygen species, including hydrogen peroxide, superoxide and hydroxyl radicals, transform and affect redox-active substances in the environment such as arsenic, uranium and natural organic matter (which may be oxidised to carbon dioxide). Production of significant quantities of reactive oxygen species on oxygenation of subsurface sediments through actions such as aquifer recharge and high flow events may alter the form and mobility of trace elements and influence the cycling of carbon and eventual efflux of carbon dioxide to the atmosphere. This project will examine the nature, extent and effect of these redox processes in selected subsurface environments. This research could have implications for contaminant transformation and fate and carbon cycling.Read moreRead less

This should help Australia benefit from the responsible use of artificial intelligence and robotics in agriculture.Read moreRead less
The effect of wastewater treatment on the ecotoxicity of chiral chemicals. This project aims to assess the environmental implications of pharmaceuticals discharged in effluents from wastewater treatment plants. Trace levels of human pharmaceuticals occur in sewage and urban waterways, but during sewage treatment, some pharmaceuticals can undergo a chemical transformation known as 'chiral inversion'. In some cases, this may convert relatively benign environmental contaminants to more ecologically ....The effect of wastewater treatment on the ecotoxicity of chiral chemicals. This project aims to assess the environmental implications of pharmaceuticals discharged in effluents from wastewater treatment plants. Trace levels of human pharmaceuticals occur in sewage and urban waterways, but during sewage treatment, some pharmaceuticals can undergo a chemical transformation known as 'chiral inversion'. In some cases, this may convert relatively benign environmental contaminants to more ecologically toxic species. This project will investigate why and how some pharmaceuticals become susceptible to chiral inversion and assess ecotoxicological differences. This work is expected to determine the significance of considering chiral inversion in environmental risk assessment, with applications to a broader range of chemicals including pesticides and industrial chemicals.Read moreRead less

Engineered osmosis (EO) is based on the principles of natural osmosis and is an emerging technology for low energy desalination and power generation by pressure-retarded osmosis. However, the process is limited by the challenge of the internal concentration polarisation (ICP) effects experienced when currently available membranes are used. Therefore, the aims of this project are to enhance our understanding of the ICP phenomenon in EO process and to evaluate strategies to mitigate the influence of ICP effects on the performance of the EO process by incorporating innovative functionalised nanofibrous support layers for thin-film composite EO membrane. A significant increase of water flux and mechanical strength is anticipated.Read moreRead less
