Wet granular materials are of immense economic importance in industries such as mining, agriculture, pharmaceuticals, and food processing. It has been estimated that operations involving the storage, handling and transport of granular materials account for over a third of the capital costs and over half of all the operating costs involved in process industries worldwide. An improved understanding of the dramatic effects of liquid on the cohesion, flow and mixing of granular materials will be of benefit to Australian industry both in terms of helping to reduce costly problems, such as caking and segregation, and in terms of the development of better particulate-based products, such as ceramics and pharmaceuticals.Read moreRead less

Combustion Synthesis of Ternary Carbides. Ti3SiC2 belongs to a group of ternary carbides that exhibit an exciting combination of the high temperature properties of ceramics, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, however a cost effective large scale synthesis method has been lacking.

Ti3SiC2 belongs to a group of ternary carbides that exhibit an exciting combination of the high temperature properties of ceramics, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, however a cost effective large scale synthesis method has been lacking. Combustion synthesis, which uses the heat of reaction as the primary energy source, has great potential for this purpose. This program will use advanced in-situ neutron diffraction experiments to map and quantify combustion synthesis reactions in the Ti-Si-C system and related systems. The results of these studies will be used to design methods of production for Ti3SiC2 and related materials.Read moreRead less

Sustainablity depends on the delivery of clean energy, pristine water and air, and the manufacture of consumer products with small environmental footprints. Modelling long-term impacts requires an understanding of the hydro-geological cycles. The technologies are well known—efficient electronics, fuel cells, lightweight composites, and so on—but delivery is not straightforward. It is clear, however, that novel materials manipulated at fine scales will be key. Transmission electron microscopy (TEM) guides the development of sustainable technologies. The new TEM facility at ANU will accelerate current studies, by enhancing the materials research portfolio, and extending national and international collaborations in materials, geological and earth sciences.Read moreRead less
