Summary
Real-time control and data analysis of remote synchrotron microprobe experiments. A Canadian-Australian collaboration to design and construct sister synchrotron microdiffraction fluorescence probes (mDFP) commenced in 2004. The Canadian mDFP will be available in the first half of 2006, at least two years prior to the sister facility at the Australian Synchrotron. The proposed project will extend this collaboration to develop a system for remote control of mDFP experiments, incorporating real-t ....Real-time control and data analysis of remote synchrotron microprobe experiments. A Canadian-Australian collaboration to design and construct sister synchrotron microdiffraction fluorescence probes (mDFP) commenced in 2004. The Canadian mDFP will be available in the first half of 2006, at least two years prior to the sister facility at the Australian Synchrotron. The proposed project will extend this collaboration to develop a system for remote control of mDFP experiments, incorporating real-time data analysis and 3D visualization. This system will enable Australian scientists to use the Canadian mDFP, and subsequently the Australian Synchrotron mDFP, from their home institutions. The resulting flexibility of scheduling and alleviation of downtime for travel will be particularly beneficial for industry users.Read moreRead less
Designed to last: novel gradient coatings for extreme environments. Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments.

Hard coatings are frequently applied to equipment operating in harsh environments. Often such coatings are highly brittle and so fragile under stress, especially at high temperatures or in corrosive environments. Premature failure can affect safety and lead to negative economic and environmental consequences. The objective of this project is to combine bioinspired microstructural design with an emerging alloying concept to produce a breakthrough in the development of engineering coatings; for example, overcoming the long standing trade-off between hardness and toughness. Such an innovative coating is expected to be highly durable in extreme conditions, and in so doing will help transform manufacturing, mining and desalination industries.Read moreRead less

Deep and smelly: exploring the roles of pressure and sulphur in hydrothermal metal transport. Hot, salty fluids carry metals in the Earth's crust and are responsible for the formation of Australia's mineral wealth. This project combines exciting new experiments with molecular-level simulations to predict metal transport, providing a sound basis for improving mineral exploration models and sustaining discovery of new deposits.
Geobiological gold cycling: Golden opportunities for the minerals industry. This project aims to develop new geobiological tools for gold exploration and processing that are rooted in a fundamental understanding of geobiological gold cycling. Given the high production costs, the sustainability of the Australian gold industry relies strongly on innovation. Yet, there are many gaps in our fundamental understanding of bio (geo)chemical gold dispersion and precipitation.

This project aims to develop new geobiological tools for gold exploration and processing that are rooted in a fundamental understanding of geobiological gold cycling. Given the high production costs, the sustainability of the Australian gold industry relies strongly on innovation. Yet, there are many gaps in our fundamental understanding of bio (geo)chemical gold dispersion and precipitation. This project aims to fill these gaps by linking biochemical pathways of gold mobilisation and resistance in bacteria to its transport and biomineralisation. This would enable the development of protein-based biosensors, bioindicators and nanovectors. These would support the development of exploration and bioaccumulation technologies that allow more economically sustainable and environmentally viable mining practices, such as enhancing production from subeconomic ore.Read moreRead less

To prevent the spread of diseases and infections through contaminated surfaces, the project intends to create new ceramic-based coatings that combine mechanical durability with broad-spectrum antibacterial activities. Around 200 000 infections, many fatal, occur in Australian hospitals each year, with contaminated surfaces being a primary source. To combat this challenge, the project aims to develop a new class of ceramic-based coatings, which are extremely robust yet highly effective in eliminating common and emerging bacteria, by uniting new antibacterial agents into a self-toughening micro-architecture. By disrupting bacterial transmission through surfaces, this project promises to protect the wellbeing of patients and healthcare professionals, and to help maintain food and water safety standards in Australia.Read moreRead less

Design of Tough, Durable and Corrosion-resistant Coatings. Coatings are frequently applied to components operating in harsh environments to enhance durability. Often such coatings exhibit low toughness and poor corrosion resistance that leads to premature failure.

Understanding the physics and chemistry of metals in hypersaline and supercritical solutions represents a major scientific challenge with wide-ranging applications in the fields of mineral processing, economic geology, or CO2 sequestration. The advent of very bright sources of x-rays (synchrotrons) and development of spectroscopic cells that can contain corrosives samples at high pressure and temperature allow for the first time the in-situ observation of these solutions. This project creates strong link between Australian and French scientists. By sharing the know-how developed at the European Synchrotron Research Facility, we aim to create a world-class facility at the Australian Synchrotron that will open in Melbourne in 2007.Read moreRead less
