The socio-economic benefits to Australia will include (i) new knowledge for the multiparameter assessment of nano and ultrafine particles, pollutants in the centre of current scientific, medical and policy debates (ii) a breakthrough in the scientific understanding of traffic generated particles in the urban atmosphere (iii) determining the toxicological impact of these particles on biological systems. The ultimate economic benefit will be improved urban design to lower human exposure to ultrafine particles, thus reducing health care cost and productivity losses. The research will also place Australia at the forefront of international progress towards better methods for achieving environmental sustainability.Read moreRead less
Development of a novel air pollution monitoring strategy - combining passive sampling with toxicity testing. Present approaches for monitoring risk of air pollutants are limited to grab sample analysis for specific pollutants using concentrations based on independent toxicological and/or epidemiological assessment of compounds. This approach does not allow for evaluation of mixtures or that a given compound may exert different toxic endpoints and is based on short sampling periods. This researc ....Development of a novel air pollution monitoring strategy - combining passive sampling with toxicity testing. Present approaches for monitoring risk of air pollutants are limited to grab sample analysis for specific pollutants using concentrations based on independent toxicological and/or epidemiological assessment of compounds. This approach does not allow for evaluation of mixtures or that a given compound may exert different toxic endpoints and is based on short sampling periods. This research aims to develop and evaluate a novel approach combining extraction of pollutants using time-integrated passive samplers and toxicological evaluation using rapid in-vitro and in-vivo assays. The outcomes provide inexpensive tools for sensitive assessment of pollutant effects and baseline data to derive intervention guidelines based on mixture toxicity.Read moreRead less
Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for ....Design tools for optimising data centre layout to minimise energy usage. Data centres are major consumers of energy worldwide, mainly through the need to cool the equipment. It has become imperative to develop the science for reducing this consumption. Rising computing demand, increasing power density, and increasing infrastructure and energy costs are major issue for data centres around the world. Our research will provide a powerful alternative to conventional thermal management techniques for cooling high-density heat loads in mixed-density environments. We will address the key issue of energy minimisation through a detailed flow analyses by the use of numerical simulations and optimisation algorithms.Read moreRead less

Monitoring of trace pollutants in water is expensive, laborious and requires sophisticated analytical techniques. Building on the research team's new technique, which uses a phyto-tox test based on photosynthesis inhibition in algae, this study will further develop and evaluate methodologies and applications for measuring phyto-toxic chemicals in environmental water samples. The project aims specifically to:
- identify suitable algae, sensitive to phyto-toxic chemicals
- determine dose-response for priority pollutants in selected algae
- evaluate critical parameters affecting measurements
- develop pre-concentration techniques.
The outcomes will provide the first on-site trace pollutant testing method allowing more effective management of water pollution

Sources, fate and exposure pathways for emerging persistent organic pollutants in Australia. Brominated flame retardants and perfluorinated chemicals have received much attention from media and environmental groups. They accumulate in biota and humans and levels are shown to be increasing. It is proposed they be included in the global treaty on persistent organic pollutants (POPs), recently ratified by Australia. This project aims to determine sources, fate and exposure pathways for these che ....Sources, fate and exposure pathways for emerging persistent organic pollutants in Australia. Brominated flame retardants and perfluorinated chemicals have received much attention from media and environmental groups. They accumulate in biota and humans and levels are shown to be increasing. It is proposed they be included in the global treaty on persistent organic pollutants (POPs), recently ratified by Australia. This project aims to determine sources, fate and exposure pathways for these chemicals with an emphasis on exposure to infants. This will provide information for risk assessment development and more effective management of these chemicals. Furthermore, the study's approach and results will contribute to a rationalization of the issues related to emerging POPs. Read moreRead less

Australia is facing severe freshwater crisis. Although there is an increasing public awareness of saving and using water efficiently, re-using water/wastewater has been neglected. In Australia, 97% of city runoff and 86% of effluent water is unproductive. How to recycle and re-use them becomes an urgent issue. This project attempts to develop novel titania based photocatalysts to convert organic contaminated water into reusable/potable freshwater. The project's innovation lies in the synthesis of highly reactive nano-structured titania surfaces in fixed form to solve downstream separation problem. Successful development of such photocatalysts will show significant environmental and socio-economic benefits to Australia.Read moreRead less
