Functional nano-porous metal membranes for sustainable separation in industrial processes. There are many waste streams that need to be purified which degrade conventional membranes. This project with local company AMS aims to develop nano-porous metal membranes as a sustainable alternative to conventional membrane materials. Highly porous and ultra-thin metal membrane sheets with narrowly distributed nano-scale pores will be fabricated and functionalised to purify both model and industrial wast ....Functional nano-porous metal membranes for sustainable separation in industrial processes. There are many waste streams that need to be purified which degrade conventional membranes. This project with local company AMS aims to develop nano-porous metal membranes as a sustainable alternative to conventional membrane materials. Highly porous and ultra-thin metal membrane sheets with narrowly distributed nano-scale pores will be fabricated and functionalised to purify both model and industrial wastewaters. This intends to lead to the production of stronger, more versatile and chemically stable membrane materials that will exhibit longer lifespan and performance. The most significant outcome is expected to be low cost metal alloys with pores below the current 100 nm benchmark and assess their thermo-chemical stability.Read moreRead less
Highly ordered and tunable extracellular DNA micro- and nanopatterns for investigating the attachment mechanisms of pseudomonas aeruginosa to surfaces. Preventing infectious bacteria from colonising artificial surfaces is a major scientific challenge. New engineered surfaces will be designed to better understand how the important pathogen Pseudomonas aeruginosa sticks to surfaces, facilitating new ways of reducing infections acquired from the surface of, for example, medical devices.
3D printed microchemical devices and systems. This project aims to address the barriers faced by 3D printing in chemistry. 3D printing can create bespoke 3D structures within a fraction of time and cost compared to traditional fabrication. However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components. Hence, this project will develop novel gold coating techniques and explore high-resolution 3D printing to overcome th ....3D printed microchemical devices and systems. This project aims to address the barriers faced by 3D printing in chemistry. 3D printing can create bespoke 3D structures within a fraction of time and cost compared to traditional fabrication. However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components. Hence, this project will develop novel gold coating techniques and explore high-resolution 3D printing to overcome these challenges. The project should generate commercially significant products (analytical platforms), technology (gold coating) and patents. The developed systems and technologies will address Australian research challenges in advanced manufacturing and enable on-site environmental monitoring.Read moreRead less
Solution and surface speciation evolution during chalcopyrite leaching. This project will contribute to the development of a more effective industrial leach process for chalcopyrite, the source of more than 50 per cent of the world's copper, and will lead to substantially reduced processing costs and environmental impact, due to removal of the existing smelting step. In addition, the processing of currently uneconomic low grade ores would become economic.
Particle-stabilised bubble and droplet interfaces. Small particles may replace or supplement detergents in a broad range of applications. This project will provide the fundamental knowledge to optimise the use of particles to stabilise foams and emulsions in a controlled manner. This will transform economically important processes in the mining, food science or personal care industries.

Equipment for Advanced Surface Analysis. Equipment for advanced surface analysis:
This project aims to establish equipment for advanced surface analysis to provide Australian researchers with cutting-edge capabilities in surface science. Vital chemical and physical reactions often occur at surfaces. Understanding these reactions requires analysis of the composition and electronic structure of the surface and near-surface regions.

This project aims to establish equipment for advanced surface analysis to provide Australian researchers with cutting-edge capabilities in surface science. Vital chemical and physical reactions often occur at surfaces. Understanding these reactions requires analysis of the composition and electronic structure of the surface and near-surface regions. Neutral impact collision ion scattering spectroscopy and inverse photoemission spectroscopy measure concentration depth profiles and electronic structure. The depth resolution of the profiles is in the order of the distance between two neighbouring atoms in a solid or liquid and is the best currently achievable. The equipment providing these capabilities is expected to support research with applications in photovoltaics, catalysis, colloid surfaces and interfaces, coatings and nanocomposites.Read moreRead less
Emulsion explosives for rock blasting in extreme geothermal environments. This project aims to understand the underlying mechanisms behind the physical and chemical breakdown of ammonium nitrate based emulsion explosives used for mining in geothermally active regions. It will apply this knowledge to develop a new class of high temperature- and pressure- resistant emulsion explosives. The resulting technology will be used in the safe and efficient mining of precious mineral deposits, such as gold ....Emulsion explosives for rock blasting in extreme geothermal environments. This project aims to understand the underlying mechanisms behind the physical and chemical breakdown of ammonium nitrate based emulsion explosives used for mining in geothermally active regions. It will apply this knowledge to develop a new class of high temperature- and pressure- resistant emulsion explosives. The resulting technology will be used in the safe and efficient mining of precious mineral deposits, such as gold, in geothermally active regions worldwide. The project will benefit the Australian mining industry by allowing mining of resources at deep levels, creating more jobs and increasing Australia's export earnings.Read moreRead less
The microbe factory: a novel approach to benign minerals processing. The purpose of this project is to reduce the environmental impact of current mining practices. The anticipated outcome of this project is the replacement of toxic chemicals used in the separation of minerals with the novel use of environmentally benign microbes.

This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry.

Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting. However, the current sulphidisation method is neither efficient nor widely used. This project will tailor sulphidisation reactions to generate desirable surface products that are not sensitive to flotation conditions. The intended outcome of this project is to provide a step change value in processing low quality resources while minimising the environmental effects of stockpiles.Read moreRead less
