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
ARC Centre of Excellence - Centre for Free Radical Chemistry and Biotechnology. Free radical chemistry is of increasing importance in the manufacture of improved plastics, paints and related materials, in helping restrict oxidative processes that can lead to adverse human health and also to the degradation of important industrial materials. The research will contribute to promoting & maintaining good health by developing new methods for reducing the impacts of ageing as well as in the treatment ....ARC Centre of Excellence - Centre for Free Radical Chemistry and Biotechnology. Free radical chemistry is of increasing importance in the manufacture of improved plastics, paints and related materials, in helping restrict oxidative processes that can lead to adverse human health and also to the degradation of important industrial materials. The research will contribute to promoting & maintaining good health by developing new methods for reducing the impacts of ageing as well as in the treatment of several life-threatening conditions such as stroke. Industrial applications include better surface coatings for preserving metals, and additives to improve the quality and shelf life of beer and wines.Read moreRead less

Summary
In-situ elevated temperature nano-indentation. In-situ elevated temperature nano-indentation: Nano-indentation has revolutionised the characterisation of the mechanical properties of materials. It permits the elastic, plastic and cracking response to be probed at the nano-scale. This project will provide a state-of-the-art Hysitron nano-indenter configured to permit isothermal elevated temperature operation (up to 650 degrees Celsius). The unit will be the only one in Australia with this capabil ....In-situ elevated temperature nano-indentation. In-situ elevated temperature nano-indentation: Nano-indentation has revolutionised the characterisation of the mechanical properties of materials. It permits the elastic, plastic and cracking response to be probed at the nano-scale. This project will provide a state-of-the-art Hysitron nano-indenter configured to permit isothermal elevated temperature operation (up to 650 degrees Celsius). The unit will be the only one in Australia with this capability and amongst the few available globally. Temperature is the single most important parameter in material processing. This facility will permit the assembled team to be among the first in the world to apply this technique to the development of new materials with superior processing performance in addition to enhanced behaviour in service.Read moreRead less
