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. 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 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
A fast and effective automated insider threat detection and prediction system. Threats from insiders directly compromises the security, privacy and integrity of Australian e-commerce, large databases and communication channels. This project will provide an essential step in combating this criminal activity by developing methods to detect such threats and secure the public's information against exposure and identity theft.
Electrodeposited Cathodes with Tunable Stoichiometry for Alkaline Batteries. The growing dependency on intermittently-available renewable energy sources has resulted in metal-ion batteries being adopted as the most common solution; yet its fabrication requires multi-stage high-temperature processing leading to high costs, quality issues, and reduced service life. Thus, the present project targets the room-temperature fabrication of binary and ternary oxide cathodes by a single-step, high-yield, ....Electrodeposited Cathodes with Tunable Stoichiometry for Alkaline Batteries. The growing dependency on intermittently-available renewable energy sources has resulted in metal-ion batteries being adopted as the most common solution; yet its fabrication requires multi-stage high-temperature processing leading to high costs, quality issues, and reduced service life. Thus, the present project targets the room-temperature fabrication of binary and ternary oxide cathodes by a single-step, high-yield, cost-effective technique and their integration into Na-ion batteries with minimal and no processing. The expected outcomes from this novel and efficient device fabrication can lead to significant commercial, social, and environmental benefits owing to the advancement of the battery industry and associated job creation.

Fluidised bed biosorption-flocculation granular activated carbon (FBBSF-GAC) for membrane filtration in wastewater reuse. Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluen ....Fluidised bed biosorption-flocculation granular activated carbon (FBBSF-GAC) for membrane filtration in wastewater reuse. Water resource is limited and has been continuously decreasing. The idea of recycling and reusing of wastewater has been adopted for irrigation, industry and other non-potable uses. In Australia, wastewater reuse is now considered a key strategy for conserving water at national, state and local level. In this study, the proposed treatment unit is to produce a superior effluent quality for water reuse while minimize membrane fouling of the membrane filtration system. Hence, it will benefit water industries globally and communities in Australia. There will be a major export opportunity from Australia to supply efficient, low-cost and sustainable flocculant together with an improved treatment system worldwide.Read moreRead less
Sustainable surfactants from Australian oilseeds. This project aims to develop a new generation of sustainable surfactants utilising Australian-grown oilseed feedstocks. These molecules are designed to replace current materials made from petroleum and palm oil, to fulfil a key role as the next generation of bio-resourced detergents and emulsifiers.

This project aims to develop a new generation of sustainable surfactants utilising Australian-grown oilseed feedstocks. These molecules are designed to replace current materials made from petroleum and palm oil, to fulfil a key role as the next generation of bio-resourced detergents and emulsifiers. The work seek to develop a library of new molecules to better understand the relationship between molecular structure and performance, through cutting edge lab testing and utilising national infrastructure, guiding the use of new components in formulating new products. It is anticipated that the surfactants generated will find uses in household cleaning and personal care products, providing high value chemicals from key Australian crops.Read moreRead less

Next-generation latent fingermark detection using functional nanomaterials. This project aims to develop a nanotechnology-based fingermark detection technique applicable in standard police laboratories and crime scenes. Current methods only detect half the fingermarks on an object, so many criminals are not identified. This project will use silicon oxide nanoparticles with a luminescent dye to target fingermark secretion components and address interference from substrate chemistries and background luminescence. Moving away from traditional detection methods is expected to improve law enforcement outcomes, as fingermarks that current technologies cannot detect will be visualised for the first time.Read moreRead less
A new management tool for effective wastewater source control. The use of recycled wastewater can dramatically increase the water supply capacity. However, the potential health risk from possible containments in recycled wastewater must be mitigated. This project aims to develop an effective wastewater source management tool for safeguarding the recycled water production and usage.
Design, Evaluation, and Selection of Novel Pt(IV) Complexes as Anticancer Agents. Platinum anticancer drugs are arguably the most widely used anticancer agents in the world but serious problems remain with toxicity and resistance. Platinum(IV) compounds have numerous advantages in terms of stability and thereby, lower toxicity. In this project we will exploit these advantages along with others that we have discovered recently and our understanding of the chemistry and biology of platinum(IV) to ....Design, Evaluation, and Selection of Novel Pt(IV) Complexes as Anticancer Agents.
