Spinal complaints present the greatest social and economic burden of musculoskeletal conditions in Australia. This reflects current realities: the cause remains unknown; 80% of the population is affected; and isolated professions perform a staggering array of interventions. The CCRE aims to target these realities and improve Australia's capacity to prevent and manage spinal disorders by supporting innovative interdisciplinary research and training. This community- and university-based centre wil ....Spinal complaints present the greatest social and economic burden of musculoskeletal conditions in Australia. This reflects current realities: the cause remains unknown; 80% of the population is affected; and isolated professions perform a staggering array of interventions. The CCRE aims to target these realities and improve Australia's capacity to prevent and manage spinal disorders by supporting innovative interdisciplinary research and training. This community- and university-based centre will align highly successful clinical and basic researchers in collaboration with a national network of spine scientists to foster interdisciplinary clinical researcher training, develop new diagnostics and therapeutics, and translate findings to the community. Through clinical research the centre aims to: (i) Advance understanding of physiology and pathophysiology of spinal pain (ii) Translate findings from basic research to clinical practice (iii) Establish coordinated multidisciplinary research to reduce the burden of spinal pain (iv) Predict and prevent the transition from acute to chronic states (v) Train a new generation of transdisciplinary clinical scientists (vi) Rapidly assess new treatment possibilities in pre-clinical studies (vii) Develop innovative technologies for diagnostics and therapeutics (viii) Encourage Australian commercialisation opportunities for new discoveries (ix) Encourage community-user participation in direction of research programs (x) Disseminate new findings and information of evidence-based practice to patients, clinicians, insurers, government and the scientific and wider communityRead moreRead less
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

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
