The development of flexible, graded plasma surface engineered coatings for superior interfacial performance. The next generation of intraocular lenses, medical devices to treat patients with cataracts, will be developed through application of advanced surface engineering technologies. These superior coated lenses will improve biocompatibility and function, leading to additional benefit for the forecasted 2.7 million Australians with cataracts by 2021.
Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown ....Surface engineering of biomaterials for optimal bone bonding characteristics. The ideal bone-implant material is hydroxyapatite. Chemically similar to bone mineral, hydroxyapatite is capable of inducing bone ongrowth. An ideal surface coating for metal hip implants, plasma spraying has been the preferred commercial hydroxyapatite coating technique. Until recently, it was always presumed that the bioactivity of hydroxyapatite resulted from its surface chemistry. However, a recent study has shown that the bioactivity of HAp coatings strongly correlates with surface roughness on the scale of bone cells. This project will explore cell-attachment behaviour for hydroxyapatite coatings prepared by plasma spraying compared with engineered surface morphology/chemistry by microlithography and vapour coating.Read moreRead less
Functionally graded fibre-polymer composites: a novel material for spinal disk prostheses. Chronic back pain affects a significant proportion of the population and is primarily caused by failure of the spinal disk. A strong social/economic imperative exists to develop engineering solutions to this problem.

Chronic back pain affects a significant proportion of the population and is primarily caused by failure of the spinal disk. A strong social/economic imperative exists to develop engineering solutions to this problem. This project concerns the development of a novel fibre-polymer functionally graded composite material that mimics the structure of the spinal disk. The spinal disk comprises a soft core (nucleus) and a tough fibrous periphery (annulus). The graded composite approach of this proposal represents a significant advance over spinal fusion, and over the alternative spinal disk protheses in clinical use or in the patent literature.Read moreRead less

The climate debate has put the issues that this research will address at the forefront of community concern. All of the initiatives discussed herein are relevant to alternative energy sources and greenhouse gas reduction. The facility will ensure that the research undertaken will be internationally cutting edge and will hasten the adoption of technologies that will flow from the research, thereby reducing the effects of the impending energy crisis and related global pollution issues. The current capability for accurately measuring gas sorption in materials for storage and sequestration is limited in W.A. and the proposed facility will address this situation.Read moreRead less

The project is designed to explore new classes of plasmonic materials based on low-dimensional transition metal oxide and chalcogenide nanostructures. These crystals, with stratified structures and high surface affinities to charged particles, present a new frontier in plasmonics by allowing reversible stimuli induced doping and defect embedding. The project plans to focus on achieving tunable plasmonic properties across a broad spectrum from ultraviolet to infrared light. Targets are systems with low propagation losses or ultra-sensitivity towards environmental changes. The anticipated outcomes will serve as a base to establish the next generation plasmonic communication and sensing systems with active on-chip controllability, which could be used as the base of future telecommunications, energy harvesting and sensing systems.Read moreRead less

Exploitation of ‘smart materials’ is a major opportunity for 21st century Australian manufacturing if cost effective bulk production is available. Metamaterials are ideal building blocks for such new-age materials, being dielectric/metal composites structured on sub-wavelength dimensions, offering diverse properties unavailable in natural materials. Fibre drawing is a proven mass-production technology for translating the structure of a (macroscale) preform to microscale and has recently been applied it to fabricate microscale metamaterials. By overcoming fundamental instabilities, this project will transform the technique to manufacture nanoscale structured composites and demonstrate practical metamaterial-based optical devices with unique properties.Read moreRead less
