Wet Granular Materials: A Three-Dimensional Study Using X-Ray Microtomography. 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.

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

This optical floating-zone furnace, the first in Australia, will support and encourage the growing number of local researchers in these fields. It will allow them to take much better advantage of the new research reactor and synchrotron being constructed in Australia by maximising their ability to grow crystals of technologically and scientifically important materials, particularly electronic and magnetic materials, for fundamental and applied research at those facilities.Read moreRead less
New carbon phases synthesized under extreme conditions. This project aims to address one of the major fundamental puzzles in carbon science; how to experimentally synthesize new phases of carbon predicted by theory. This could be approached via a combination of high pressure and high-energy ion irradiation to transform novel nano-carbon precursors. The expected outcomes include new phases of carbon with unexplored properties, an understanding of the pathways for synthesis of carbon materials, an ....New carbon phases synthesized under extreme conditions.

Summary
An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. 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 ....An analytical transmission electron microscope for the investigation of functional materials, earth processes and novel condensed matter. 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
Grain-boundary sliding in high-temperature ceramics: mechanical spectroscopy of high-purity magnesium oxide. The demise of elastic behaviour in materials stressed at sufficiently high temperature limits the usefulness of ceramics for structural applications, and is also responsible for reduced wave speeds and associated attenuation of seismic waves in the Earth's interior. Yet the nature of the transition in fine-grained materials tested at high temperature from elastic through anelastic to vis ....Grain-boundary sliding in high-temperature ceramics: mechanical spectroscopy of high-purity magnesium oxide. The demise of elastic behaviour in materials stressed at sufficiently high temperature limits the usefulness of ceramics for structural applications, and is also responsible for reduced wave speeds and associated attenuation of seismic waves in the Earth's interior. Yet the nature of the transition in fine-grained materials tested at high temperature from elastic through anelastic to viscous rheology remains poorly understood. Through a combination of mechanical testing by torsional forced oscillation/ microcreep methods of carefully fabricated and characterised specimens of polycrystalline MgO and associated micro-mechanical modelling we seek to clarify this fundamental and general aspect of high-temperature mechanical behaviour.Read moreRead less

The ultimate aim of this project is to identify high performance, environment-friendly i.e. lead free, piezoceramic materials capable of replacing the currently market dominant, lead-based materials. Such piezoceramics have widespread industrial applications. Understanding the factors that control the capacity of such materials to respond to applied stress or electric field is critical to the discovery, optimization and, ultimately, industrial exploitation of such materials. Through comprehensive experimental and theoretical studies of a number of such materials this project will enhance the ability of industry to develop new and improved materials. Development of advanced materials is a designated National Research Priority area. Read moreRead less

Modern materials scientists and engineers are driven by world-wide competition to develop new technology and manufactured devices. The trend has for some time been towards miniaturisation and one of the main challenges lies in effectively characterising nanostructures that are produced as a key step in research and development of advanced materials. The proposed electron microscope and detectors will provide a state-of-the-art analytical facility to support the cross-disciplinary materials science and nanotechnology research at the Australian National University. It will also provide an important training facility for students and early-career researchers and will be available to investigators from other Australian institutions.Read moreRead less
