Geological sequestration of carbon dioxide in deep saline aquifers: coupled flow-mechanical considerations. Deep saline aquifers have been routinely proposed as sites for long-term, large-scale storage of carbon dioxide (CO2) emissions, as an option to assist the abatement of global warming. This project investigates expected engineering behaviour of deep saline aquifer reservoirs and their stability following CO2 sequestration.
Innovative hands-free technology to give the severely disabled greater mobility control. Half of the serious neurological injuries in Australia result in tetraplegia. Combined with other disabilities that involve severe mobility impairments the cost to the community economically, psychologically and socially is huge.

Half of the serious neurological injuries in Australia result in tetraplegia. Combined with other disabilities that involve severe mobility impairments the cost to the community economically, psychologically and socially is huge. This new Australian technology will facilitate effective sharing of control between a disabled person and a computer control system, taking advantage of their unique strengths and enabling each to aid the other in areas of weakness. The social and personal benefits are potentially very large. Scope also exists to significantly reduce healthcare costs and to develop a new industry in hands-free technology.Read moreRead less
Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high ....Controlling nickel-base alloy high temperature corrosion in CO2-rich gases. Coal provides cheap energy for Australia but emits carbon dioxide (CO2) in large quantities. The solution is to improve the efficiency of coal fired power plants and use CO2 capture technology. This is feasible by raising steam temperatures and using oxyfuel process where coal is burnt in oxygen rather than in air. Thus the hot combustion gas is very rich in CO2 plus water vapour, which is however very corrosive at high temperatures. Traditional steels are inadequate. Instead, nickel-base alloys are needed. This project aims to investigate the corrosion behaviour of nickel base alloys in carbon dioxide - water atmospheres, and ways of preventing this corrosion by controlling gas composition and appropriate alloying, which is essential for next generation power plant design.Read moreRead less
Role of oxide grain boundaries in controlling high temperature corrosion of steels by carbon dioxide-rich gases. Advanced coal combustion technologies make carbon dioxide capture possible, but require improved materials to handle hot carbon dioxide-rich gases. These gases are surprisingly corrosive and the corrosion process is not fully understood. This project aims to achieve this understanding and to provide the basis for future alloy design.
Improved design and operational efficiency of small wind turbines in unsteady flows. The purpose of this research is to improve the design and performance of small wind turbines for energy generation. The expected outcomes are novel control strategies and mechanical designs that account for unsteady aerodynamics and its effects on structural loads and power quality. Recommendations to improve current design standards will be made.
Heat-resisting iron-nickel base alloys in challenging new applications: oxygen permeabilities and resistance to internal oxidation. There is a pressing need to develop heat resisting alloys which can function adequately in higher operating temperatures and gas mixtures rich in carbon and hydrogen to be handled in advanced technologies for power generation. The expected outcomes of this project will provide the basis for design/selection of these more corrosion-resistant alloys.

Mining large negative correlations for high-dimensional contrasting analysis. Negative correlations are widely embedded in real life applications, but in-depth research has rarely been conducted due to its high level of complexity. This project aims at efficient algorithms and frontier theory for finding large negative correlations, to enable smart information use in bioinformatics to promote Australia's leading role in data mining research.

This project aims to address the intermittency of renewable energy sources using novel thermal storage media. Advanced heat transfer modelling and in situ neutron diffraction and imaging are intended to be used to optimise the microstructure of newly developed miscibility gap thermal storage systems. The new media store energy as the latent heat of fusion of one phase in a stable, high thermal conductivity inverted microstructure. The high energy density of the latent heat (0.5-4.5 Mega Joules/Litre) requires storage volumes as little as five per cent of those relying upon heat capacity and the metal matrix has a hundred-fold greater thermal conductivity than current systems. It is proposed that a range of such materials will be engineered for concentrated solar thermal and space heating applications.Read moreRead less
