Tissue engineering (TE) of heart valves is a new approach to cultivate a functional heart valve from human autologous cells. This innovative study aims to develop the technology to transplant cells onto a 3D biocompatible valve scaffold that is capable of mimicking native valve. The work proposed is a ground breaking study that will encompass development of a new biomaterial, manufacture of scaffolds using the Fused Deposition Modelling rapid prototyping process, hemodynamic optimisation and in vitro cell culture. This will advance our knowledge in cellular and scaffold technologies and may ultimately lead to the development of a TE heart valve.Read moreRead less

Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic ap ....Fluid dynamics and mechanical stress of tissue heart valves. Major problems with thrombo-embolic complications and leaflet failure and calcification still exist with bioprosthetic valves. Valves fabricated from polyether urethanes are efficient and can offer more resistance to calcification. No complete study on the haemodynamics and structure interactions is found in literature. Moreover, todate the effect of aortic wall motion on the blood flow has never been examined. A complete holistic approach to simulataneuosly simulating the fluid dynamics, the valve motion and the stress in a synthetic Polyether urethane valve is proposed. Cell adhesion study will also be carried out. The findings may yield to new insights into valve research.Read moreRead less

The evolutionary structural optimization (ESO) is an Australian initiative, which has made a significant impact on modern structural optimization. In advanced materials areas, Australia has well-established infrastructure and world-class expertise. Exploitation of ESO to advanced materials design will be of "exclusive significance" to Australia. More importantly, the new material design technology will present to Australia an opportunity to lead in this rapidly-growing area, which will definitely underpin Australia's standing as a major contributor and developer in a global materials market. It is expected that fresh classes of futuristic materials can be developed in a cost-effective fashion and add great economic benefits to Australia.Read moreRead less

This project aims to investigate molecular mechanisms involved in the formation of undesired biological deposits on synthetic materials and thereby help establish the scientific basis for the rational design of materials with improved compatibility with biological fluids and the engineering of a new generation of biomedical implant devices and bio-diagnostic devices. It is well known that proteins accumulate on synthetic solid surfaces. This project proposes to investigate whether lipids and lipoproteins also play key roles in the initiation of biological adsorption processes. Combined with the study of the interfacial forces responsible, this information will guide the design of preventative strategies.Read moreRead less

Evolution of Contact Damage in Layer Structures. Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour.

Brittle layer structures (eg brittle coating on ceramic substrate) can be much more damage tolerant than their constituent material components - cracks tend to remain contained within the coating. Very little is known about the factors that control this behaviour. This project will exploit unique local expertise in modelling damage evolution to fill a niche in a large study being carried out at the National Institute of Standards (NIST) in the U.S.A.
