Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish ....Self-zoning in natural uraninite: radiation driven chemical separation. In this project we aim to explore and define the effects of the substitution of lead and rare earths on the crystal chemistry of uranium dioxide (uraninite) and related minerals, towards establishing the oxygen stoichiometry (as a measure of oxygen fugacity) of these materials both in nature and in synthetic materials. This project will use synthetic materials to understand the variability of oxygen stoichiometry, establish accurate and precise structures for the oxides, and distinguish both long range and short-range order which is critical to understanding both natural and synthetic U-oxides. This will help to define the geochemical conditions leading to the formation of deposits like Olympic Dam towards potential economic benefit.Read moreRead less

Summary
In Situ Spectroscopy of Particle and Material Interfaces. We seek to establish a world-class research facility for the in situ study of particle and material interfaces. The two techniques that will form the backbone of the facility are Raman scattering and surface second harmonic generation (SHG). The proposed in situ spectroscopy facility will be multi-disciplinary, contributing to research in chemistry, chemical engineering, geology, forensic science, and biotechnology.

The proposed in situ spectroscopy facility will be multi-disciplinary, contributing to research in chemistry, chemical engineering, geology, forensic science, and biotechnology. The establishment of the facility will enhance research in the areas of minerals processing, mineralogy, water treatment, and drug delivery.Read moreRead less
SYNCHROTRON MICROPROBE METALLURGICAL CASE STUDIES. The micro-focus capabilities of synchrotron techniques (XRF, XRD, XAS) will enable the high resolution spatial correlations required to advance the understanding of the three systems to be studied:
- Activation for flotation of sphalerite with varying iron contents;
- Arsenic leaching as a function of local structure, phase and mineral assemblage;
- Optimisation of ferrous alloy microstructure on cryogenic treatment.

- Arsenic leaching as a function of local structure, phase and mineral assemblage;
- Optimisation of ferrous alloy microstructure on cryogenic treatment.
These case studies have been chosen to specifically target the minerals processing and manufacturing industrial sectors and will be used to increase industrial awareness of the potentials of synchrotron techniques prior to the commissioning of the Australian Synchrotron in 2007.

Microdiffraction: advanced capabilities for spatial resolution, trace phase detection and solid object analysis: Microdiffraction offers two principal capacities that traditional powder diffraction (PD) facilities cannot: it enables small areas to be examined on a spatially resolved basis enabling identification, and it enables analysis of minor, but frequently crucial phases and analysis of samples that are not in a powder form thus enabling non-destructive examination. These capabilities provide powerful complementary capacity to existing SEM, QEM-SCAN, ToF-SIMS and PD facilities. Potential and existing applications are numerous and include minerals analyses; forensic applications; micro-electronics; corrosion analyses; art analysis/conservation; archaeology; materials; polymers; thin films; dielectric properties; liquid crystals; and drug characterisation.Read moreRead less
