Quantum Coherences in Artificial Light-Harvesting Complexes. The aim of this project is to relate efficient energy and electron transfer processes in molecular materials to the presence of quantum coherences. The ongoing debate on the role of quantum coherences in the efficient harvesting of sunlight of photosynthesis appears to be limited by the complexity of the biological systems and a lack of high instrumentation sensitivity. Using molecular systems and a highly sensitive method, this projec ....Quantum Coherences in Artificial Light-Harvesting Complexes. The aim of this project is to relate efficient energy and electron transfer processes in molecular materials to the presence of quantum coherences. The ongoing debate on the role of quantum coherences in the efficient harvesting of sunlight of photosynthesis appears to be limited by the complexity of the biological systems and a lack of high instrumentation sensitivity. Using molecular systems and a highly sensitive method, this project aims to reveal the effects of molecular conformation and geometry on quantum coherences. The outcome is likely to improve our understanding of nature's remarkable ability to harvest energy efficiently from the sun and foster new approaches that increase the efficiency of light-harvesting systems.Read moreRead less
Non-Covalent Interactions Probed by Velocity Map Imaging. Our research program concerns non-covalent interactions, which are of fundamental importance in a range of areas including condensed phase chemistry, the folding of large molecules, biomolecule shape, host-guest chemistry and molecular self-assembly. We probe non-covalent interactions through studies of van der Waals molecules, which involve two or more molecules or atoms held together by non-covalent forces.

Our research program concerns non-covalent interactions, which are of fundamental importance in a range of areas including condensed phase chemistry, the folding of large molecules, biomolecule shape, host-guest chemistry and molecular self-assembly. We probe non-covalent interactions through studies of van der Waals molecules, which involve two or more molecules or atoms held together by non-covalent forces. Our group has developed new experimental methodologies for determining the strength of intermolecular interactions and these will be used to study the effect of 3-body interactions. Because of their role in chemical reaction, we will also undertake detailed studies of complexes involving radical species.Read moreRead less
Structural and functional investigations of the human transcription machinery by ion mobility-mass spectrometry. This project will apply emerging mass spectrometric technologies to gain previously inaccessible insight into human transcription factor proteins. This will reveal new avenues for intervention in human disease states related to aberrant gene expression, while developing innovative methods for the study of complex protein assemblies.
Friction and capillary forces. Reducing friction forces is important for improving the performance of moving components in devices, and also useful for relieving people from pains at joints. In ambient conditions, confined liquids have a great influence on friction forces because an attractive force is induced by capillary condensation and adsorption between the surfaces. The correlation between capillary and friction forces will be clarified by force measurements with newly developed surface fo ....Friction and capillary forces. Reducing friction forces is important for improving the performance of moving components in devices, and also useful for relieving people from pains at joints. In ambient conditions, confined liquids have a great influence on friction forces because an attractive force is induced by capillary condensation and adsorption between the surfaces. The correlation between capillary and friction forces will be clarified by force measurements with newly developed surface force apparatuses in various conditions. Theoretical interpretation of influences of molecular layered liquids between the sliding surfaces on frictional behaviour will be also given based on thermodynamics.Read moreRead less

Improved oral bioavailability of anticancer drugs will improve the quality of life of patients, reduce health care costs and provide broader benefits to the community. The Australian biotechnology/pharmaceutical industries can share in a greater proportion of the US$50 billion market for specialised drug delivery, which is increasing by 20% annually. Australia's scientific competitiveness will be strengthened in the fields of nano-encapsulation and colloidal delivery.Read moreRead less
X-ray snapshots of chemical transformations in open framework materials. The aim of this project is to unearth structural insights into the chemistry of coordinatively unsaturated metal complexes – reactive species lacking their full complement of binding groups – by isolating them within a carefully designed metal-organic framework and examining them via single crystal X-ray diffraction. Such intrinsically reactive species play an important role in metal-based catalysis, but their definitive st ....X-ray snapshots of chemical transformations in open framework materials. The aim of this project is to unearth structural insights into the chemistry of coordinatively unsaturated metal complexes – reactive species lacking their full complement of binding groups – by isolating them within a carefully designed metal-organic framework and examining them via single crystal X-ray diffraction. Such intrinsically reactive species play an important role in metal-based catalysis, but their definitive structural characterisation remains a significant challenge. This project aims to facilitate a detailed understanding of how these species bind and activate substrates and thus provide important first steps towards developing novel adsorbents for separations and efficient catalysts.Read moreRead less

Energetics and dynamics of solvated biologically relevant molecules using liquid microjet and ion imaging technologies. The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule.

The shape of many biomolecules in solution plays a critical role in determining their biological activity and function. It is known that the bonds that form between the biomolecules and the water solvent control this shape. However, very little is known about the strength and structure of these bonds at different sites around the biomolecule. Many experiments have informed us about the strength of the bonds, others have told us where the bonds occur. This project will provide both pieces of information for the first time, allowing us to better understand, and therefore control, biological function. This work will assist in the development of new biotechnology processes, especially in the emerging area of proteomics.Read moreRead less
