Salty gas: the ecological risk of saline effluents from coal seam gas and other hydrocarbon resources. The objective of this project is to predict the effect of saline water produced from coal and coal seam gas extraction activities on freshwater systems. The findings will assist decisions on whether to permit discharge of such waste water, and if permitted under what conditions (e.g. water quality criteria) so as to prevent environment damage.
Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and frac ....Nature's mechanisms for leaching and remobilising metals. This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.Read moreRead less
Development of Advanced Detection Systems for Accelerator Mass Spectrometry. This project aims to expand significantly the range of isotopes available for accelerator mass spectrometry at the Australian National University to include the ability to detect manganese-53, nickel-59 and uranium-236 to ultra-sensitive concentrations. To achieve this, my extensive experience in fundamental nuclear physics will be exploited to develop a gas-filled magnet for the detection of mangnese-53 and nickel-59, ....Development of Advanced Detection Systems for Accelerator Mass Spectrometry.

To achieve this, my extensive experience in fundamental nuclear physics will be exploited to develop a gas-filled magnet for the detection of mangnese-53 and nickel-59, and a time-of-flight detector to detect uranium-236. This project has applications in the topical areas of climate change and nuclear safeguards, as well as applications in the earth sciences and the management of nuclear waste.Read moreRead less
Reactive flow through porous media by micro-imaging. Australia is embarking on the development of major gas fields offshore Western Australia. These developments are very costly and techniques to manage the risk in development are well sought after. This project assists in risk management of tertiary recovery methods and CO2 storage. Further, it can contribute significantly to the accurate forward modelling of storage of hazardous materials and pollution remediation strategies. The project could ....Reactive flow through porous media by micro-imaging. Australia is embarking on the development of major gas fields offshore Western Australia.

Further, it can contribute significantly to the accurate forward modelling of storage of hazardous materials and pollution remediation strategies. The project could shape important decisions in the future and impact on environmental risk assessment.Read moreRead less
Mathematics and computing for integrated stockyard-centric management of mining supply chains. Blended mineral products, such as coal and iron ore, make a strong contribution to Australia's economy. Blending occurs in stockpiles, so to realise product value, stockyard and supply chain operational plans must align with blend targets. This project will provide new mathematical and computational planning tools to maximise this value.
Green Manufacturing of Graphene from Indigenous Natural Graphite and Graphene-based Nanofiltration Membranes. This project aims to investigate radical new approaches to reduce chemical and energy requirements for transformation of indigenous natural graphite to a high-value material graphene. The graphite which will be used is the by-product of the Uley mines of South Australia. Graphene is an atomically thin arrangement of carbon atoms with combinations of remarkable chemical inertness, strengt ....Green Manufacturing of Graphene from Indigenous Natural Graphite and Graphene-based Nanofiltration Membranes. This project aims to investigate radical new approaches to reduce chemical and energy requirements for transformation of indigenous natural graphite to a high-value material graphene. The graphite which will be used is the by-product of the Uley mines of South Australia. Graphene is an atomically thin arrangement of carbon atoms with combinations of remarkable chemical inertness, strength, and massive surface area. Utilising fluid phase dispersed graphene, this project aims to develop scalable and industrially-adaptable methods to manufacture thin yet mechanically robust, inert, fouling-resistant, highly-permeable graphene-based asymmetric membranes. These advanced membranes are expected to find wide application in reducing discharge of mining effluents and recovery of precious metals.Read moreRead less
Probing gold in hot ore fluids: experiments and molecular dynamics simulations. In order to efficiently discover vital new mineral resources for Australia, explorers must understand the fundamental controls on ore formation. The lack of data for soluble metal behaviour in hot fluids at high pressure is a significant impediment to our understanding of deposit formation and for the application of industrial processes, such as hydrometallurgy. This project will gain molecular-level understanding of ....Probing gold in hot ore fluids: experiments and molecular dynamics simulations. In order to efficiently discover vital new mineral resources for Australia, explorers must understand the fundamental controls on ore formation. The lack of data for soluble metal behaviour in hot fluids at high pressure is a significant impediment to our understanding of deposit formation and for the application of industrial processes, such as hydrometallurgy. This project will gain molecular-level understanding of the fundamental chemistry of gold transport and deposition in high temperature, high-pressure, carbon dioxide-rich fluids and gold colloid systems, using multiple novel experimental techniques and molecular dynamics simulations that make use of Australia’s cutting-edge experimental and computational facilities.Read moreRead less

This research will enable corporations to identify the points of greatest leverage over corporate and facility level health, safety, environmental and community (HSEC) performance and to develop strategies that successfully achieve their HSEC objectives. It will provide broader national benefits in (i) reducing workplace injury and environmental degradation at multiple facilities across Australia and (ii) increasing productivity and economic benefits (by doing so at reduced cost to companies). The study will also benefit the Australian and regional communities by identifying strategies that facilitate better community-company relations. Read moreRead less

The physical chemists; and the biologists, soil scientists and engineers who need them, have lived in parallel universes. Despite claims for relevance, the standard text book chemistry is unsatisfactory in a myriad industrial and basic applications. Identification of where theories went wrong has been made. The repair of current theories will provide better predictive experimental design principles that get to real world solutions faster. There is a genuine paradigm shift in progress. Redressing deficiencies of present theories will provide a better intuition for scientists who need a predictive intuition from physical chemistry for optimal experimental design.
