The project aims to design a new class of tough hydrogels to address issues in engineering complex soft and robust structures. These hydrogels have superior properties compared with current materials as they are biologically active, processable by various manufacturing techniques, elastic and have a capacity for rapid self-recovery that are ideal for soft tissues. Their physical property is tunable by modification of their compositions that enable construction of complex seamless structure such as valved conduit with anistropic property. Expected outcomes of this project include new insights into material design, multi-physics modelling, and multi-material additive manufacturing for broad applications in soft robotics and medical implants.Read moreRead less

Fibre-Polymer Composites With Graded Microstructure. 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 current generation of spinal disk protheses (metal plates with springs/polymers as shock absorber ....Fibre-Polymer Composites With Graded Microstructure. 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 current generation of spinal disk protheses (metal plates with springs/polymers as shock absorbers). Chronic back pain affects a significant proportion of the population and is primarily caused by failure of the spinal disk. Therefore a strong social and economic imperative exists to develop engineering solutions to this problem.Read moreRead less
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

The aim of this proposal is to develop a facility for the mechanical properties analysis of material surfaces. The facility will enable an understanding of the performance of materials in a wide range of contact and abrasion situations and in very small volumes such as thin films and components of multiphase composites. The unique features of the proposed facility are that it is capable of analysis down to exceptionally low sub-micron length scale, under multiple forms of loading and over a range of temperatures. It is applicable to the design of abrasion resistant materials, characterisation of very thin surface films for applications such as microelectronics and biomedical implants and design of advanced composites.Read moreRead less

This project aims to create a novel bilayer ferroelectric material structure that provides giant electromechanical response at the nano-scale. Traditional electromechanical devices based on ferroelectric materials including position sensors, mechanical actuators, and ultrasonic transducers rely on bulk form. As technology moves toward integrated functionalities, future electro-mechanical materials need to be scaled down to thin film form. Currently, doing this induces mechanical constraints that dramatically suppress the electromechanical response. Using this approach one layer relieves this mechanical constraint while the other gives a giant electromechanical response, providing a pathway for future functional devices. 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
