This interdisciplinary project aims to develop a personalised air pollution exposure monitoring system, leveraging the ubiquitousness and advancements in mobile phone technology and state of the art miniaturisation of monitoring sensors, data transmission and analysis. Airborne pollution is one of the top contemporary risks faced by humans; however, at present individuals have no way to recognise that they are at risk or need to protect themselves. It is expected that the outcome will empower individuals to control and minimise their own exposures. This is expected to lead to significant national socioeconomic benefits and bring global advancement in acquiring and utilising environmental information.Read moreRead less
A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of ....A Fundamental Understanding of Methane Driven Denitrification. Eutrophication in waterways due to the presence of nutrients including nitrogen is a well-recognised environmental problem. Moreton Bay, for example, used to receive 3,300 tons of nitrogen each year from point sources. Stringent nitrogen discharge limits have therefore been imposed on most wastewater treatment systems across Australia. Nitrogen removal from wastewater is commonly accomplished in a biological way involving the use of bacteria. The project aims to investigate a particular bacterial community, which is able to perform nitrogen removal from wastewater with methane as a renewable carbon source. The project will therefore lead to more sustainable wastewater treatment systems.Read moreRead less

This project creates an innovative science and technology to solve the critical problem of hydrogen storage that will enhance the international reputation and impact of Australian research in nanoscience and nanothechnology. Realizing the practical hydrogen storage will also enable hydrogen vehicles soon in Australia that adds Australia great potential to reducing the reliance on fossil fuels and greenhouse emissions.Read moreRead less
Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transpor ....Multiphase flow and transport in complex coastal wetland systems. Salt marshes play an essential role in maintaining Australia's coastal bio-diversity. They also function as barriers to fluxes of terrestrial pollutants to our coastal sea. Australia has a large number of salt marshes listed by the Ramsar Convention as coastal wetlands of international importance but many of them are subject to loss and degradation due to competing land uses. This project, examining in detail the flow and transport processes in marsh soils, will lead to (1) better understanding of the marsh's response to anthropogenic stress; and (2) improvement of strategies and methods for marsh wetland preservation and restoration.Read moreRead less
Understanding Fugitive Greenhouse Gas Emissions from Wastewater Systems for Reliable Accounting and Effective Mitigation. Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide. T ....Understanding Fugitive Greenhouse Gas Emissions from Wastewater Systems for Reliable Accounting and Effective Mitigation. Climate change caused by greenhouse gas (GHG) emissions is one of the most serious challenges facing mankind. Substantial reductions in emissions must be achieved, with responsibility shared by all industrial sectors. Wastewater systems contribute to GHG emission through not only energy consumption but also direct emissions of fugitive GHG such as methane and nitrous oxide. This project aims to deliver the urgently needed knowledge and technology support to the Australian wastewater industry to achieve reductions in fugitive emissions. The research will also provide support to the greenhouse office via more reliable estimation of such emissions.Read moreRead less

Algal control using multi-functional, cold plasma activated microbubbles . Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies.

Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies. Paradoxically, algal biotechnology is a growth industry with application in food, agriculture and energy; realising this potential requires state-of-the-art technology to optimise production, harvesting and extraction. The aim of this proposal is to develop cutting edge technology that uses cold plasma activated microbubbles to control algal populations. We propose that by tuning the plasma composition, this technology could both selectively disrupt and destroy algal matter and enhance algal cell growth, benefiting both water and biotechnology industries.

The two techniques to be developed and tested here will allow the measurement of the 3D density and velocity fields in lakes and estuaries using only simple instruments and with minimum lake obstruction. Coupled with a Real Time Management System, these techniques can be used to validate numerical models and to simulate scenarios, such as future flood events, which have the potential for contamination of water quality. The output from these simulations is then used, again in real time, to evaluate the new Index of Sustainable Functionality of the water body. When augmented with the results from this research we would have a tool that would help manage lakes and reservoirs to optimize the water quality, while maintaining the supply.Read moreRead less
