Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom.

X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in mixtures. The current proposal is aimed at introducing new technology into the Australian National Beamline Facility that will greatly improve the quality and quantity of experiments that can be performed and extend studies into dilute solutions and protein samples.Read moreRead less

A Fourier transform ion cyclotron resonance ("FT-ICR") mass spectrometer equipped with electrospray ionisation (ESI) plus a "benchtop" matrix assisted laser desorption ionisation time of flight (MALDI-TOF) mass spectrometer are required to support the research of ca 28 research groups, including 44 postdoctoral fellows, and 138 honours and postgraduate students. By means of its high resolution and (MS)n capabilities, the FT-ICR-MS will provide key structural information on a wide range of synthetic and natural chemical substances, including sequence (e.g. peptides) and fragmentation patterns, while the MALDI-TOF instrument will be used primarily for high through-put proteomic analyses.Read moreRead less
TiO2 nanoparticle design and photocatalysis applications. The aim is to design nanosized TiO2 photocatalsysts with superior photoactivity using various synthesis paths. Nanosized TiO2 particles will be prepared using sol-gel, aerosol and plasma processing, their physical and chemical properties will be closely studied and their photocatalytic ability will be assessed. Such tailor-made photocatalysts have significant commercial potential value, as they would be highly suitable for the photooxidat ....TiO2 nanoparticle design and photocatalysis applications. The aim is to design nanosized TiO2 photocatalsysts with superior photoactivity using various synthesis paths. Nanosized TiO2 particles will be prepared using sol-gel, aerosol and plasma processing, their physical and chemical properties will be closely studied and their photocatalytic ability will be assessed. Such tailor-made photocatalysts have significant commercial potential value, as they would be highly suitable for the photooxidation of organic compounds and the photoreduction of metal ions in wastewaters. Findings from this work will pave the way for a "green" technology such as photocatalysis to become more efficient and hence a competitive alternative to conventional water treatment methods.Read moreRead less
Structural studies of titanyl and zirconyl sulfate hydrates. This project aims to provide knowledge that will inform the development of new methods of extraction and refining of titanium from ilmenite ores. In addition the knowledge gained in this research will aid the design and synthesis advanced ceramics and nanocomposites, and will provide the fundamental understanding of material structures that are required to adequately control the formation of such materials.

Nanoporous Molecular Frameworks: Chirality, Host-Guest Chemistry and Nanoscale Templation. Molecular frameworks are a new class of nanoporous material that promise a range of applications due to their reversible, selective guest-exchange and their great structural and chemical versatility. This project addresses three points of focus within this area: 1) the use of homochiral (handed) frameworks for molecular enantioseparations, 2) the mechanisms of guest-exchange in these systems, and 3) the us ....Nanoporous Molecular Frameworks: Chirality, Host-Guest Chemistry and Nanoscale Templation.

This project addresses three points of focus within this area: 1) the use of homochiral (handed) frameworks for molecular enantioseparations, 2) the mechanisms of guest-exchange in these systems, and 3) the use of these materials as porous templates within which other nanostructured materials may be grown. In addition to having considerable fundamental interest, the work promises a number of significant commercial benefits in the areas of drug purification and nanomaterials.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.
