Degradation of Trace Contaminants Using Sonochemistry and Peroxide Scavenging Advanced Oxidation Processes. Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investiga ....Degradation of Trace Contaminants Using Sonochemistry and Peroxide Scavenging Advanced Oxidation Processes. Sonochemical degradation of hazardous organic compounds in aqueous solution has been examined extensively in recent years and found to be an effective means of waste treatment however the scavenging of hydroxyl radicals by the relatively high concentrations of hydrogen peroxide produced limits the amount of reactive radicals accessible to target molecules. In this project we will investigate, by both experimental and computational means, options for the regeneration of hydroxyl radicals through use of hydrogen peroxide. Methods of particular interest include use of Fenton's reagent and ozone.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
Metabolic engineering of Zymomonas mobilis for higher value fermentation products. This project will provide an opportunity to revolutionise the Australian chemical and sugar industries. Unlike the traditional methods of the petrochemical industry, bioconversion of carbohydrates to chemicals such as succinic acid via fermentation is cosiderably environmental friendly.

This project will provide an opportunity to revolutionise the Australian chemical and sugar industries. Unlike the traditional methods of the petrochemical industry, bioconversion of carbohydrates to chemicals such as succinic acid via fermentation is cosiderably environmental friendly. For the sugar industry this project will provide an opportunity to produce not only conventional sugar products but also high value commodities via the process integration of succinic acid production using agricultural residues such as bagasse. This will contribute to significant levels of job creation in Australia, and further benefits will be that such products will be important both for import replacement and export potential.Read moreRead less

In a time of predicted severe water shortage in the Asia Pacific, the University of Western Sydney and the Council of Scientific and Industrial Research, India have developed research into community based water resources management for regional townships and communities. The objective of this proposal is to connect the two water research organisations in a cross cultural comparison of their respective research programs and to develop a generic model of regional community water use management for developed and developing countries, appropriate to the Asia-Pacific.Read moreRead less
Photodegradation of Oestrogenic Pollutants in the aquatic environment. Recent media attention has highlighted the problem of oestrogenic pollutants in the aquatic environment. This research proposes to investigate Photocatalysis of oestrogens in water using the magnetic titanium dioxide particles developed at the Centre for Particle and Catalyst Technologies in the University of New South Wales, Sydney.

Recent media attention has highlighted the problem of oestrogenic pollutants in the aquatic environment. This research proposes to investigate Photocatalysis of oestrogens in water using the magnetic titanium dioxide particles developed at the Centre for Particle and Catalyst Technologies in the University of New South Wales, Sydney. The natural oestrogens 17b-oestradiol, oestrone and oestriol and the synthetic oestrogen 17a-ethynyl oestradiol (the main constituent of the contraceptive pill) will be investigated in the photocatalytic system. Degradation will be monitored using various analytical techniques. Other commercial catalysts will also be investigated and compared with the magnetic catalyst and previous catalysts tested.Read moreRead less

Environmental quality and health in the elderly; The Australian situation and international comparison. The elderly are a vulnerable population group that should receive particular attention in health policy. They are a group of considerable and growing size that contributes disproportionately to total health burden. Although residential environment is likely to influence health and well-being among the elderly, the evidence-base for appropriate policy and practice is lacking. Improved understa ....Environmental quality and health in the elderly; The Australian situation and international comparison. The elderly are a vulnerable population group that should receive particular attention in health policy. They are a group of considerable and growing size that contributes disproportionately to total health burden. Although residential environment is likely to influence health and well-being among the elderly, the evidence-base for appropriate policy and practice is lacking. Improved understanding of the role of relevant environmental factors could lead to substantially reduced morbidity and mortality (and associated costs) for the key outcomes: falls, and cardiovascular and respiratory disease. Results will contribute to the international evidence-base in this increasingly critical area of research, policy, and practice. Read moreRead less

Macquarie University and the University of Copenhagen have expertise in fluorescence detection and whole cell biosensors respectively. The project will take advantage of these skills and develop a sensitive assay for monitoring biosensor bacteria in soil. The technology will be significant as it will enable real time analysis of antibiotic production in situ through the detection of GFP expression. This work will then be used to isolate new antibiotic produces and will be extended to research into the bioavailability of toxic compounds and stress. An existing collaboration between the two institutions will be extended enabling the transfer and application of biosensor technology to Australia.Read moreRead less
In situ measurements of the electrostatic properties inside photosynthetic reaction centres: correlation with the energy conversion function of the protein. The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation.

The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation. Coupling of electron and proton transfer is catalysed at the level of a ubiquinone cofactor. In order to understand how the redox properties of this cofactor are fine tuned by the protein environment, we plan to probe the ubiquinone site using a voltage-sensitive fluorescent dye. This exciting multidisciplinary project will contribute to the understanding of how protein matrices influence and govern the midpoint redox potential of their cofactors and the environments of theirRead moreRead less
