Intervalence Transfer in Dinuclear and Oligonuclear Polymetallic Assemblies. Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration. By design of ....Intervalence Transfer in Dinuclear and Oligonuclear Polymetallic Assemblies. Mixed-valence compounds (such as the pigment Prussian Blue) have been known for over two centuries, and possess important conductivity, magnetic and spectral properties. Electron transfer between the elements of different valency (intervalence charge transfer, IVCT) gives rise to absorbances in the red or near-infrared region of the spectrum which provide fundamental information on the electron migration. By design of target di- and higher nuclearity polymetallic species, the project will study IVCT phenomena to understand electron movement, allowing rational development of applicable materials such as catalysts, light-activated devices and non-linear optical materials.Read moreRead less
Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is a ....Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is applicable to polymerization kinetics studies, as well as providing new means for the determination of materials lifetimes. The development of pro-fluorescent markers as indicators for polymer degradation would be a significant outcome for materials where component failure has a major negative impact.Read moreRead less

Graft copolymers from starch and synthetic monomers. Polymer dispersions, manufactured as latexes in large quantities in Australia and elsewhere, have myriad applications, such as in adhesives, bitumen modifiers, paints and paper coatings. This project will create the enabling science to replace by starch the current synthetic products used to stop these dispersions from coagulating. This will create new uses for renewable resources and will reduce environmental insult by avoiding the leaching o ....Graft copolymers from starch and synthetic monomers. Polymer dispersions, manufactured as latexes in large quantities in Australia and elsewhere, have myriad applications, such as in adhesives, bitumen modifiers, paints and paper coatings. This project will create the enabling science to replace by starch the current synthetic products used to stop these dispersions from coagulating. This will create new uses for renewable resources and will reduce environmental insult by avoiding the leaching of biologically incompatible chemicals. By using starch from crops suited for Australia's arid climate, the new technology will reduce both our dependence on imported products and our greenhouse gas emissions.Read moreRead less
Synthesis of nanocomposite polymers with targeted properties. This project aims to synthesise novel nanocomposite polymers by living radical polymerisation in water and to understand the way polymer microstructure and nanomorphology control material properties. This will provide the enabling science so that nanomaterials with targeted properties can be tailor-made for biomedical and speciality-coatings applications, and thus dispense with the current trial-and-error methodology.

This will provide the enabling science so that nanomaterials with targeted properties can be tailor-made for biomedical and speciality-coatings applications, and thus dispense with the current trial-and-error methodology. The innovations in this project are the novel synthesis of complex polymer architectures in water, and the first quantitative and qualitative structure-property correlations for such materials. This will also result in a deepened understanding of the mechanisms governing the formation of these nanocomposites.Read moreRead less

Light can generate an optical force to capture small objects. This requires intense light – a laser, which limits optical trapping in catalysis applications. This project aims to apply plasmonic nanoparticles with normal-intensity light to take advantage of plasmonic-generated optical forces for catalytic chemical synthesis. The optical trapping/releasing of small molecules is highly selective and responsive to molecule structure and so presents a great opportunity to radically alter chemical synthesis pathways, which will be illustrated with reactions on liquid-solid and gas-solid interfaces. This highly innovative strategy will be used to discover new nitrogen-based syntheses which are both fundamentally and industrially important.Read moreRead less
