'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deli ....'Designer defects' - A new approach to functional oxide interfaces. The conventional approach to metal oxide interfaces is 'perfection at all costs' with growth tuned to minimise defects and unwanted chemical intermixing. This project aims to turn this approach on its head by creating interfaces with 'designer defects' that become the critical portion of a functional device. This project proposes that one can promote functionality by making use of new physical properties that arise from the deliberate introduction of structural and electronic mismatches at an interface. Such purposely induced 'designer defects' in epitaxial oxide thin films will allow new properties to be achieved in nanoscale layers. This is expected to lead to a new class of functional materials to be used in sensors and nanoelectronics.Read moreRead less
Domain wall nanoelectronics : The wall is the device. This project investigates the nanofabrication and atomic-scale manipulation of domain walls in multiferroic oxide thin films. Proximal scanning probe writing in conjunction with nanolithography is exploited to precisely engineer domain wall configurations, to be used as functional elements. The experiments will be supported by the multiscale modeling theory of multiferroics.

These instruments are designed to provide fundamental insights into physical and biological systems though characterisation and fabrication of structures at nanometre length scales. These versatile platforms will support a wide range of projects covering three national research priority areas. These range from the characterisation of light alloys for improving and building Australia's Aluminium, Magnesium and Titanium alloy industries, to the study of aerosol particles for improved pulmonary drug delivery for asthma patients, the development of advanced solar cells and the study of the integrated behaviour of the soil-microbe system for sustainable agriculture.Read moreRead less
Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosiv ....Reducing gas and ash corrosion in advanced power generation. Advanced power generation using new coal combustion technologies increases energy efficiency and makes carbon dioxide capture possible, but increases the corrosion problems. This project aims to determine the corrosion behaviour of chromia-scale forming iron- and nickel-base alloys in the presence of deposits (coal ashes and salts) under carbon dioxide rich gas atmospheres. The increased understanding of alloy behaviour in hot corrosive ashes and gases, will permit more effective materials design and selection leading to more efficient and economic technologies for reliable and low cost carbon capture in energy production, waste-energy conversion and related industries.Read moreRead less
High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multipl ....High temperature corrosion induced by multiple secondary oxidants . Heat resisting chromia-forming alloys passivate successfully in clean, dry air at temperatures up to about 950°C. However, this performance is degraded by secondary oxidants (carbon, sulphur, chlorine, water vapour), leading to corrosion failure in important industries. The project aims to investigate the effect of these secondary oxidants on corrosion behaviour of chromia-forming alloys, to identify interactions between multiple oxidants within the scale, to establish the mechanisms of oxide scale penetration by foreign species, and to evaluate scales on different alloy types. The results will provide a basis for improved design/selection of heat resisting chromia-forming alloys, key to power generation industries.Read moreRead less
