With the aging of our population, issues concerning the lifetime of biological system are paramount to the quality of life and economic well being of our society. This project is closely linked to the development of prosthetic materials and structures that will improve performance and life of biomechanical devices, by providing better understanding to the mechanics of failure and failure origins of ceramic-based dental crowns and restorations, and to develop materials that will withstand exacting conditions - in body fluids - over extended lifetimes. Crown replacement is by far the most widespread of all prosthetic procedures. This project promises to help bridge the gap between physical and medical science in Australia. Read moreRead less

Novel carbon dioxide tolerant ceramic membranes for oxygen separation to improve the viability of clean energy technology. Conventional cryogenic air separation is a major economic impediment to the deployment of these low emission technologies like Callide oxyfuel combustion. This project will lead to the discovery of a new class of oxygen selective membranes for air separation with significantly reduced cost to improve the viability of these clean energy technologies.

Magneto-optical materials have a wide range of potential applications in consumer products, telecommunications and defence. Nanotechnologies based on these materials offer an even broader range of emerging applications. Understanding and participating in the development of magneto-optic technologies will therefore be critical to maintaining Australia's knowledge base and expertise in future technological advances. Given the early stages of development of these technologies, Australia's expertise in material science and the patent rights held by Australian companies in this area, Australia has the opportunity to make major contributions to this field, and the potential to capitalise on the application of these technologies in niche markets.Read moreRead less

Atomistic mechanisms of the mechanical behaviour of nanostructured silicon carbide films. Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications.

Advanced silicon carbide (SiC) ceramics are leading candidates for applications in high-power, high-speed machining and high-temperature structural components. Superhardness and high ductility (or high fracture toughness), which have been realized in some nanostructured (ns) SiC films and nanowires, respectively, are desirable properties for many applications. This project aims to understand the mechanisms behind the exceptional properties in ns SiC and to explore the possibility of realizing the two properties in the same ns SiC. The results obtained from this research will be very important for guiding the structural design of SiC with exceptional mechanical properties which will have a wide range of structural applications.Read moreRead less

Australia has vast resources of unconventional oil/gas, which require hydraulic fracturing to stimulate production. This project aims to develop advanced low-density high-performance proppants from industry waste for hydraulic fracturing. This will be achieved by selecting purer SiO2 raw material, carefully designing the porous structure, and fully understanding its relationship with strength and pack conductivity. Low-density means no chemicals in proppant transportation and application. Successful development of such high-performance proppants will significantly increase Australia oil/gas exploration and production with an environmental acceptable technology, a leap forward for the oil/gas industry in Australia and the world.Read moreRead less
