Investigation and Prediction of the Novel Properties of Dendrimers. Dendrimers are a new class of highly branched polymers, which have, until now, been difficult to characterise by conventional means. This project will develop and apply molecular simulation techniques to reveal the chemical and physical properties of dendrimers and their interactions with other molecules. These novel molecules potentially have beneficial applications to areas such as drug delivery and electronic materials. Th ....Investigation and Prediction of the Novel Properties of Dendrimers.

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
Production of a compact disk summarising the evolution and impact of Boger fluids. In 1977 the discovery of a unique class of materials, now called Boger fluids, was reported in the Journal of Non-Newtonian Fluid Mechanics. These materials have had a huge impact in the development of non-Newtonian fluid mechanics, to the extent that the Institute of Non-Newtonian Fluid Mechanics in the UK have offered to make a cd documenting the impact of these materials.

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
Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. Thi ....Reducing wear on rotary coal pulverisers. The aim of this project is to develop an understanding of the small-scale flows and particle breakage required to permit optimised redesign of the attrition stage of the 36 coal pulverisers at Gladstone Power Station, which, because of erosive wear, currently have a maintenance budget of $4M per year. CFD-DEM simulation of the air and particle flows will be used to determine particle flow patterns, particle-particle and particle-wall impact energies. This information will be input to comminution and wear models to predict pulveriser performance and wear patterns. Simulation results will be validated using measurements from scale visualisation and working models.Read moreRead less

The processing of blue green algae rich waters and subsequent release of algal metabolites causes taste and odour problems and toxins that affect potable water safety. This project will define a preferred approach to the processing of these waters and provide quantitative analysis tools to help water authorities guarantee water quality and safety. The defined process routes and analysis procedures will also result in better water conservation (lower net water losses in processing). This will allow better regulation of water quality, safety and management by water authorities and improve consumer confidence in the potable water supply.Read moreRead less
Novel conversion process for carbon dioxide to chemicals. This project aims to develop a novel sorption enhanced material and system to convert atmospheric carbon dioxide (CO2) to methanol. Climate change is one of the primary long-term problems confronting humankind today. Since the production of CO2 through burning fossil fuel is far greater than the current usage of CO2, there is currently little alternative to storage. As a result, there is concerted effort globally to develop alternate use ....Novel conversion process for carbon dioxide to chemicals.

Ultrafiltration of whole milk solutions will be extended to maximise the product protein concentration. Electrodialysis and nanofiltration will be tailored to separate salts from lactose and produce 'designer' products with minimum wastage and energy consumption. Production of lactitol from dairy lactose, a potential new manufacturing operation for Australia, will be assessed. This project will result in diversion of quality ingredients from commodity markets to products with significant added value. The Korumburra region will benefit financially and socially from expansion in the local dairy industry.
