All-carbon molecules in metal complexes - novel materials and intermediates. An important requirement for the future is new materials with unusual properties that can be controlled. The need for ever smaller electronic devices requires knowledge about appropriate properties (particularly electronic) of molecules designed to model devices such as wires, switches, etc. This work seeks to design, measure and evaluate such molecules, which are based on chains of carbon atoms linking metal centres ....All-carbon molecules in metal complexes - novel materials and intermediates. An important requirement for the future is new materials with unusual properties that can be controlled. The need for ever smaller electronic devices requires knowledge about appropriate properties (particularly electronic) of molecules designed to model devices such as wires, switches, etc. This work seeks to design, measure and evaluate such molecules, which are based on chains of carbon atoms linking metal centres which can gain or lose electrons readily. As the electronic structure changes, so do the physical (photo, solid-state) and chemical properties (reactivity). Improved understanding of these features will benefit development of advanced technology and new materials.Read moreRead less
Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself tog ....Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself together. This research will use nature's light harvesting elements, namely porphyrins, and our ability to precisely control their position with respect to each other to build new, more efficient solar cells.Read moreRead less
New synthetic strategies towards higher order fullerenes. Fullerene or C60 is a novel soccer-ball shaped molecule with many potential applications as new materials and pharmaceutical drugs. This project aims to develop novel methods for the preparation of new fullerene derivatives that will have potential future applications in materials science, medicinal/pharmaceutical chemistry and chemical synthesis.
Asymmetric Synthesis of Bioactive Alkaloids and Analogues via Chiral, Polylfunctionalized-Pyrrolidines. Alkaloids are plant products that have many useful biological and pharmaceutical properties. Many of these compounds have potential as antiviral and anticancer therapeutics. This project aims to develop novel methods of preparing bioactive alkaloids and their structural analogues. These compounds potentially have applications as new potent and less toxic pharmaceutical agents.
The fate of dietary selenium in vivo; a direct approach to linking chemical form with biological activity. Dietary selenium supplementation has great potential as a preventative treatment for a range of human health conditions, including cancer, that widely affect the Australian population. However, the adverse effects of such treatments are not fully recognised. This project will increase our knowledge of how selenium compounds are stored and utilised in the body and relate the information to c ....The fate of dietary selenium in vivo; a direct approach to linking chemical form with biological activity. Dietary selenium supplementation has great potential as a preventative treatment for a range of human health conditions, including cancer, that widely affect the Australian population. However, the adverse effects of such treatments are not fully recognised. This project will increase our knowledge of how selenium compounds are stored and utilised in the body and relate the information to clinical observations regarding dietary intake of selenium and other compounds. The new understanding generated will delineate the conditions for safe intake, so that the beneficial effects associated with selenium supplementation may be harnessed more effectively.Read moreRead less
Development of Pyrrolopyrimidines as Inhibitors of ATP-Binding Proteins. This project seeks to generate analogues of natural products that have been found to be active against cancer cells and tropical parasites. The new materials produced by this project will aid in the study of biochemical processes involved in diseases such as cancer and lymphatic filariasis, thus leading the way to development of these compounds as potential treatments for such diseases.

This project aims to develop imaging tools and protocols for the detection of lipids in brain tissue and cells. This project expects to generate advanced methodologies to display specific lipid classes and their corresponding structures within tissues and cells, with the ability to be detected and correlated with multiple techniques, which represent a currently unavailable capacity. The expected outcomes of this project are improved opportunities to study lipid biology at the cellular and sub-cellular level across a wide range of in vitro and in vivo models. The outcomes of this project should provide significant knowledge to tackle modern societal challenges in healthy ageing, brain pathologies and neurodegenerative diseases.Read moreRead less
Cross sections for electron scattering from molecules and radicals of technological and environmental relevance. We will use two state of the art crossed beam spectrometers to measure absolute differential and integral cross sections for low energy electron scattering from molecules and their molecular fragments (radicals). The species to be considered are those of significant industrial (e.g. C2F4, C4F8 and CF2) and environmental (e.g. CO2 and H2O) interest, with the cross sections we will mea ....Cross sections for electron scattering from molecules and radicals of technological and environmental relevance.

The species to be considered are those of significant industrial (e.g. C2F4, C4F8 and CF2) and environmental (e.g. CO2 and H2O) interest, with the cross sections we will measure being crucial to our modelling both the processes involved in plasma enhanced chemical vapour desposition of semiconductor devices and the spectral emission characteristics of planetary atmospheres. The modelling will be conducted self-consistently with our enhanced statistical equilibrium simulation code, which is unique to Australia.Read moreRead less
