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. The natural oestrogens 17b-oestradiol, oestrone and oestriol and the synthetic oestrogen 17a- ....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. 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
Branching in acrylic polymers: analysis and mechanistic understanding. Some polymers can be branched. This branching has major effects on the end-product performance of a polymer, for example in adhesives and the flexibility of rubbery materials. Full quantification of this branching (the lengths of branches and the rates of the processes that create them) has been impossible hitherto. Two new complementary techniques, a new analytical method developed by the applicant Fellow in Paris, and a new ....Branching in acrylic polymers: analysis and mechanistic understanding. Some polymers can be branched. This branching has major effects on the end-product performance of a polymer, for example in adhesives and the flexibility of rubbery materials. Full quantification of this branching (the lengths of branches and the rates of the processes that create them) has been impossible hitherto. Two new complementary techniques, a new analytical method developed by the applicant Fellow in Paris, and a new synthesis technique developed in Sydney, will be used as the platforms to devise the first means of determining this information and thus understanding and quantifying branching.Read moreRead less
