Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of g ....Gassing Mechanism and Stability of Foamed Explosive Emulsions. Mining of minerals such as coal involves crushing the surrounding rock strata, or the mineral ore itself, with emulsion explosives. One of the most important properties determining suitability of an emulsion explosive to a particular mining operation is its velocity of detonation, which can be adjusted by varying the number and size of air bubbles distributed in the emulsion matrix. The present project aims to develop new ways of generating air bubbles, to gain fundamental understanding of the foaming mechanism in currently used gassing techniques, and to invent ways to stabilise large bubbles within the emulsion. The project will provide scientific underpinning for the development of a new range of emulsion explosives manufactured by Orica for Australian and international markets, maintaining the Orica's position as a leader in the field of emulsion explosives.Read moreRead less
Role of Reactive Particles in Explosive Emulsions. Concentrated water-in oil explosive emulsions are widely used in the minerals industry because they are cheap, easily detonated and relatively safe to handle. Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and ch ....Role of Reactive Particles in Explosive Emulsions.

Their explosive energy can be significantly increased when reactive particles are introduced into the emulsion matrix. To do this, the interaction between the solid, oil, and water phases needs to be optimised. This investigation will increase our basic understanding of the physical and chemical interactions that occur between the particle and the oil-water interface, and develop a more efficient explosive that can be produced continuously on a commercial scale.Read moreRead less

Summary
An advanced thermogravimetric analysis system for world-leading research in clean energy, catalysis, material science and nanotechnology. Many chemical reactions occurring in solid materials during heating significantly affect the materials' stability, and subsequently affects the processes of production of clean energy, material synthesis, catalyst preparation, and nanotechnology.

Many chemical reactions occurring in solid materials during heating significantly affect the materials' stability, and subsequently affects the processes of production of clean energy, material synthesis, catalyst preparation, and nanotechnology. No equipment currently exists in Australia that will mitigate the wide range of conditions in such reactions in materials processing. This situation impedes research progress in Australia, disadvantages Australian research students, and ultimately makes our research less competitive internationally. The establishment of the proposed apparatus will increase the competitiveness of Australian science and engineering, and contribute to the development of new Australian technologies that are important to the Australian economy and to environmental sustainability.Read moreRead less

A High-Throughput Neutron Spectrometer for The Study of Atomic and Molecular Motion at ANSTO. Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed.

Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of option to an existing spectrometer that will broaden its user-base from specialised applications in physics to more general applications in physics, chemistry, materials-science and biology. This additional option provides a totally new way for Australian scientists to study atomic and molecular motions. Read moreRead less

Terrorist attacks have cost Australians much human grief and billions of dollars. Containing the consequences of a blast or impact is crucial to survival and restricting damage to critical civilian/defence infrastructure. Thin-walled structures are used extensively in such infrastructure. There is a lack of knowledge about their behaviour when subjected to impulse and blast loads. The investigators will establish the most economical means of designing passive blast protection into thin-walled structures and hence, Australia's critical infrastructure. This knowledge will be transferred into design standards and Australia's limited defence resources.Read moreRead less

This submission aims to establish an integrated facility for studying the kinetics of solid and gas-solid reactions at elevated temperatures and high pressures; a piece of infrastructure that is urgently needed in Australia. The facility will consist of a high-pressure thermal gravimetric analyser (TGA) able to operate at up to 5 MPa, which will be coupled to a mass spectrometer (MS) for identification and quantification of gaseous reaction products. The facility constitutes unique and significant national research infrastructure for the simultaneous acquisition of mass loss kinetic measurements together with characterisation and quantification of emission rates of gaseous fragments generated in the reaction. As a major outcome, the facility will provide a means for consistent investigation of kinetics of elemental reactions occurring in solids, or on solid surfaces during pyrolysis and gasification processes at high pressure.Read moreRead less
