- 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.

Summary
A glow discharge optical emission spectrometer for challenging surfaces. This project aims to address a critical surface characterisation gap in Australian research by the implementation of a glow-discharge optical emission spectrometer. Determining the composition depth profile of chemically complex surfaces that are rough, fragile, and air-sensitive is very challenging. The project will allow rapid and accurate elemental depth profiling of surface layers up to hundreds of microns in thickness ....A glow discharge optical emission spectrometer for challenging surfaces. This project aims to address a critical surface characterisation gap in Australian research by the implementation of a glow-discharge optical emission spectrometer. Determining the composition depth profile of chemically complex surfaces that are rough, fragile, and air-sensitive is very challenging. The project will allow rapid and accurate elemental depth profiling of surface layers up to hundreds of microns in thickness and with nanometre resolution. Critically this instrument allows glovebox-to-instrument analysis without surface preparation, preserving the in-situ state of the surface. This will fast-track research in battery materials, new methods to control corrosion, and the design of advanced engineered surfaces.Read moreRead less
Highly ordered and tunable extracellular DNA micro- and nanopatterns for investigating the attachment mechanisms of pseudomonas aeruginosa to surfaces. Preventing infectious bacteria from colonising artificial surfaces is a major scientific challenge. New engineered surfaces will be designed to better understand how the important pathogen Pseudomonas aeruginosa sticks to surfaces, facilitating new ways of reducing infections acquired from the surface of, for example, medical devices.
Particles at Interfaces—Controlling Detachment. Small, solid particles affect the processes used by the Australian mining industry to recover precious metals and valuable minerals in ways that remain poorly understood. The outcomes of this project will make significant contributions to the fundamental understanding of the role of particles in emulsions and foams. The results will also ultimately transfer to, and have a substantial impact on, the pharmaceutical industry, which is poised to use na ....Particles at Interfaces—Controlling Detachment.

Short circuiting redox enzymes. Enzymes that catalyse oxidation or reduction reactions can be integrated with an electrode in the development of biosensors. A key challenge is enabling an electrical current between the enzyme and the electrode and this project aims to probe this phenomenon to provide an enzyme system that operates with greater efficiency than in nature.
