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. 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 ....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. 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. An understanding of the factors that maximise the containment of cracks is essential to the design and development of the next generation of advanced layer composites for many biomechanical and other engineering applications.Read moreRead less

This project aims to establish a Scanco microCT 50 high resolution X-Ray microtomography system, to non-destructively visualise and quantitatively characterise complex samples, including advanced composites, tissue engineering constructs, biological tissues, minerals and fossils. The non-destructive characterisation of these samples is critical to advance research. The versatile system offers high spatial resolution (down to 500 nm voxel size) and large sample size (up to 100 mm diameter). The project will enable progress in advanced composites, additive bio-manufacturing, physiology of biological tissues and palaeontology which will benefit Australian science. Additionally, through commercialisation and the formation of new companies, the project could potentially result in economic and health benefits to the wider Australian population and economy.Read moreRead less

This project will lead to the development of new biocompatible, biodegradable, porous materials ideally suited to many applications in tissue engineering. These new biomaterials will be relatively inexpensive to manufacture, via simple processes using non-toxic reagents. The key properties of the biomaterials will be controllable by appropriate choice of starting materials. The availability of these new biomaterials will facilitate future developments in tissue engineering, which will ultimately lead to improved medical outcomes in areas as diverse as joint and bone repair and organ regeneration. Local manufacture of these biomaterials would also contribute to the development of the Australian biotechnology industry.Read moreRead less
Optimum design of controlled drug delivery systems. Controlled drug delivery systems are ideal to achieve localised release of drugs at an effective rate for a prolonged period. They have the merit of optimising drug absorption by a body, relieving patients from frequent administration and high dosage of drugs which often result in drug wastage, patients' inconvenience and more importantly the side effects that can be fatal. The success of this project will (1) enhance the Australia pharmaceutic ....Optimum design of controlled drug delivery systems.

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses.

Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less

Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their inter ....Bone regulation - cell interactions to disease. Many bone disorders such as osteoporosis, Paget's disease and chancer related bone diseases are directly related to disruption of communication pathways between bone cells leading to imbalances in bone remodeling. Although these disorders are common and cause considerable suffering, in most cases little is known about the mechanisms responsible for dysfunctional remodeling. Understanding the communication network between bone cells and their interaction with drugs is essential in order to develop new therapies and to effectively design novel biological compatible bone implants. This research proposal closely aligns with national research priority two, i.e., promoting and maintaining good health (ageing well, ageing productively).Read moreRead less
