Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety ....Porphyrin-Based Supramolecular Assemblies and Arrays - Model Systems for the Construction of Photosynthetic Mimics. Crown ether-based multichromophoric systems will be used to mimic the steps through which plants convert light into chemical energy. The crown bridging units allow a variety of metal and organic cations, which provide electronic and structural roles, to be non-covalently bound within their cavities. These systems are advantageous over other photosynthetic models in that a variety of electron transfer mediators can be examined in a readily controlled and systematic way simply through the choice of cation. In this way, the role played by molecular recognition in the modulation of long-range electron transfer can be evaluated. This work will lead to designing better artificial solar energy converters and molecular electronic devices.Read moreRead less
Characterization and design of new soft electrolyte materials. The use of fossil fuels for energy generation contributes heavily to global warming. The development of new types of energy sources (e.g. fuel cells) and energy storage devices (e.g. batteries) is of crucial importance to ease this pressure on the environment. The search for new, high energy-density electrolyte materials for these applications is intense. Recently, plastic crystal materials have been identified as potential electroly ....Characterization and design of new soft electrolyte materials. The use of fossil fuels for energy generation contributes heavily to global warming. The development of new types of energy sources (e.g. fuel cells) and energy storage devices (e.g. batteries) is of crucial importance to ease this pressure on the environment. The search for new, high energy-density electrolyte materials for these applications is intense. Recently, plastic crystal materials have been identified as potential electrolytes in a variety of electrochemical devices. These materials show high conductivity at ambient temperatures in their plastic (or soft) phase. This project aims to further investigate and develop these novel materials.Read moreRead less

Summary
A High-Throughput Neutron Spectrometer for The Study of Atomic and Molecular Motion at ANSTO. Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of ....A High-Throughput Neutron Spectrometer for The Study of Atomic and Molecular Motion at ANSTO. Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of option to an existing spectrometer that will broaden its user-base from specialised applications in physics to more general applications in physics, chemistry, materials-science and biology. This additional option provides a totally new way for Australian scientists to study atomic and molecular motions. Read moreRead less

Recent work by the applicants has shown that nanocrystalline titanates and aluminates hold considerable promise as lithium battery electrodes. Nanocrystalline anatase materials showed considerably greater lithium intercalation ratios compared with their microcrystalline counterparts, and doping with vanadium showed further improvements in capacity. Sol-gel synthesised V-doped anatase materials produced an initial discharge capacity of 428 Ah/kg compared with only 280 mAh/kg for the undoped anatase electrode in the same Li test cell.In this project different dopants and preparation conditions will be investigated to produce nanocrystalline rutile and aluminate materials as potential candidates for high capacity lithium battery applications.Read moreRead less
