Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.Read moreRead less

For Australia to maintain its position as a world leader in the science of metals processing it must have the capability for state-of-the-art physical simulation. The present proposal is for the purchase and installation of two leading edge simulation tools: a high rate/short inter-pass hot deformation simulator and a hot equal channel angular extrusion press. Advanced hot deformation simulation is required for the development and optimisation of "fast" industrial processes and for understanding the complex microstructural reactions associated with them. High temperature extrusion is required for the development of ultra-fine and nano-grained light metals.Read moreRead less

Development of a New Type of Large-Area Robust Superhydrophobic Surfaces (MWN). Electrochemical manipulation will be used to produce robust metal surfaces of controlled roughness and characteristic size of the surface features in the 10-1000 nanometre range. Subsequent surface modification (e.g. self-assembled monolayers, silane chemisorption, plasma polymer deposition) will render these surfaces superhydrophobic.

Electrochemical manipulation will be used to produce robust metal surfaces of controlled roughness and characteristic size of the surface features in the 10-1000 nanometre range. Subsequent surface modification (e.g. self-assembled monolayers, silane chemisorption, plasma polymer deposition) will render these surfaces superhydrophobic. The surfaces will have highly depressed adhesion properties and hence a significantly improved chemical resistance and corrosion stability. A viable procedure for the making of polymer imprints from the metal surfaces will be developed. This will form the basis of a new method for cheap fabrication of various superhydrophobic surfaces with large areas and specific functionality.Read moreRead less
Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminish ....Quantum Nanostructure Positioning for Breakthrough Quantum Photonics. The integration of quantum nanostructures in optical devices has been proposed to improve the efficiencies of existing optical devices and create new classes of quantum photonics. Limiting progress is that many nanostructures are made through bottom-up processes with inherently randomly distributions, making integration into devices problematic. Lithographic nanostructure fabrication is rarely an option as it leads to diminishes performance. Here, we propose a new and unique nanostructure positioning technique incorporated directly into the growth process. It interfaces bottom-up technologies with device fabrication, facilitating incorporation of nanostructures in photonic devices, and may be transferrable to a variety of other systems.Read moreRead less

Cold rolled steel strip, produced by BHP Steel, is a precursor material for production of internationally recognised Australian products ZINCALUMER Steel and COLORBONDR Steel. Lubricating oils supplied by Quaker Chemical are used during the cold rolling process. When exposed to the direct fired annealing process, nanolayer surface residues can develop from rolling oil films and adversely affect subsequent steel surface wetting by the molten zinc alloy. This collaborative research project will investigate the fundamental nature of nanolayer residue formation, using advanced thermal and surface analysis techniques, with the aim of determining the factors influencing residue formation and reducing their impact.Read moreRead less
Nanoscale Particle Control by Rigid Biomineralised Surfaces. The proposed research will increase understanding of the strategies diatoms use to sort particles.

The proposed research will increase understanding of the strategies diatoms use to sort particles. Our hypothesis is that in the process of understanding how these diatom surfaces control particles, blueprints for microfluidic devices will be identified. The appeal of diatoms goes beyond consideration of the geometrical patterning on their surfaces, because their frustules (the diatomic shells) are made primarily out of silica, a material also used in nanofabrication. We expect that some of the strategies and patterns used by cells will be able to be directly transferred to microfluidics, and bypass years of empirical development in nanofabrication and lab-on-a-chip devices.Read moreRead less
