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
Materials science and superconductivity in the new Fe-based high temperature superconductors. Novel superconducting materials with high superconducting transition temperature and upper critical field are one of the most important research fields in the community of materials science and condensed matter physics.

A Direct Approach to Crystal Structure Determination - a solution to the phase problem. The purpose of this research is to determine the positions of atoms in crystals and nano-crystals. We have developed a theory that shows how to extract all of the information required to determine atomic positions from such crystals and we have carried through initial successful tests on simple materials. In particular, we have found that crystallographic phase, hitherto not directly measurable, can in fact b ....A Direct Approach to Crystal Structure Determination - a solution to the phase problem. The purpose of this research is to determine the positions of atoms in crystals and nano-crystals. We have developed a theory that shows how to extract all of the information required to determine atomic positions from such crystals and we have carried through initial successful tests on simple materials. In particular, we have found that crystallographic phase, hitherto not directly measurable, can in fact be extracted uniquely from a single electron diffraction pattern. This constitutes a solution to the phase problem in crystallography. It is now our aim to develop this method into a routine technique.Read moreRead less
Atomistic Mechanisms of Stress Relaxation in Amorphous Materials. Amorphous materials represent a major thrust in the search for new materials. Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals. Ceramic glasses are finding increasing applications in data storage, photoelectronics and fibre optics. The greatest obstacle to the application of amorphous solids is their brittleness. The goal of this project is to use accurate comp ....Atomistic Mechanisms of Stress Relaxation in Amorphous Materials. Amorphous materials represent a major thrust in the search for new materials. Metallic glasses have very high strength and can be cast to much finer tolerances than regular (polycrystalline) metals. Ceramic glasses are finding increasing applications in data storage, photoelectronics and fibre optics. The greatest obstacle to the application of amorphous solids is their brittleness. The goal of this project is to use accurate computer simulations to provide detailed pictures of how atomic motions relax stress in very different types of glasses and, through this insight, explore ways of modifying the mechanical properties of these materials.Read moreRead less
Fluctuation Effects in Non-Crystallising Liquids. Understanding the behaviour of liquids colder than their freezing temperature is important in areas as diverse as metal alloy preparation, prevention of cell damage in plants and animals at low temperatures, extending the working temperature range of new high voltage automotive batteries and controlling drug delivery in pharmaceuticals. Advances in these areas would represent important new manufacturing opportunities in industries already establi ....Fluctuation Effects in Non-Crystallising Liquids. Understanding the behaviour of liquids colder than their freezing temperature is important in areas as diverse as metal alloy preparation, prevention of cell damage in plants and animals at low temperatures, extending the working temperature range of new high voltage automotive batteries and controlling drug delivery in pharmaceuticals. Advances in these areas would represent important new manufacturing opportunities in industries already established in Australia. In this project the fundamental physical chemistry of supercooled liquids is developed and applied to a number of these technological challenges.Read moreRead less
Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism.
