Cellular and network basis of information processing in the mammalian visual system. The project aims to discover the strategies by which cells in the brain interact with each other to code the sensory input efficiently. It is expected that simultaneous recording of the activity of many neurones from the visual cortex of anaesthetised cats during visual stimulation will reveal how the biophysics of synaptic integration combined with excitatory and inhibitory inputs from different sources sculpt ....Cellular and network basis of information processing in the mammalian visual system. The project aims to discover the strategies by which cells in the brain interact with each other to code the sensory input efficiently. It is expected that simultaneous recording of the activity of many neurones from the visual cortex of anaesthetised cats during visual stimulation will reveal how the biophysics of synaptic integration combined with excitatory and inhibitory inputs from different sources sculpts the output of individual neurones. The experiments will be extended to the study of possible interactions between different areas of the brain and the study of mechanisms by which the cortical network and higher cognitive factors such as attention and memory might influence the coding of sensory information in awake animals.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
Peptide Nucleic Acid Based Sensors and Devices - An Investigation into PNA Versatility for Emerging Gene Technologies. Peptide nucleic acids (PNAs) are analogues of DNA that may have important implications as therapeutic agents for the cure of diseases based on genetic defects. The attributes of PNAs that make them potentially viable as a drug are also well suited to their development as sensors and molecular devices. In this proposal, we wish to develop a series of PNAs containing photoactive ....Peptide Nucleic Acid Based Sensors and Devices - An Investigation into PNA Versatility for Emerging Gene Technologies. Peptide nucleic acids (PNAs) are analogues of DNA that may have important implications as therapeutic agents for the cure of diseases based on genetic defects. The attributes of PNAs that make them potentially viable as a drug are also well suited to their development as sensors and molecular devices. In this proposal, we wish to develop a series of PNAs containing photoactive elements (a) as alternatives to commercially-available fluorophores, (b) for the early detection of neurodegenerative diseases and (c) to contribute to one of Science's most debated issues i.e. "does DNA mediate electron transport?"Read moreRead less
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
Low viscosity, high ionic conductivity ionic liquids for lithium metal batteries. Current consumer electronic devices rely on lithium-ion batteries to provide a high energy density power source.

There are growing safety concerns about the electrolytes in these devices after recent incidents involving fires in mobile phones. Recent advances in ionic liquids (ILs) have seen the development of new electrolytes for such devices, with enhanced physical properties that offer major safety advantages. However, the viscosity of these materials currently limit their capabilities. New IL materials to be developed in this project will pave the way for the development of safer devices and new sustainable energy industries in Australia.Read moreRead less
