Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton ....Multiscale Study on Biomechanical Roles of Soft Tissue on Bone Remodelling. The project aims to increase our knowledge of the processes of bone remodelling and the role of soft tissue in this process. Mechanical force is a key stimulus for regulating bone remodelling. A significant question in biomechanics is why orthodontics only use very small forces (1 Newton) to generate significant oral bone remodelling, whereas prosthodontics that apply three orders of magnitude higher forces (~1000 Newton) do not move dental implants. This project aims to develop new multiscale modelling and remodelling techniques in computational mechanics to explore the roles played by connective soft tissue in bone adaptation. Expected project outcomes would increase our understanding in biomechanics and affect health care disciplines such as orthodontics, prosthodontics and orthopaedics.Read moreRead less
Multiscale modelling and nondeterministic optimisation for reliable stents. This project aims to study modelling and optimisation for a more reliable design of intravascular stents. Intravascular stents are a class of lifelong micro-devices to support blood vessel for restoring circulation. Despite its remarkable initial outcome, the high rate of long-term mechanical failure remains a major concern. This project will tackle plasticity, fatigue damage and fracture across different length scales. ....Multiscale modelling and nondeterministic optimisation for reliable stents. This project aims to study modelling and optimisation for a more reliable design of intravascular stents. Intravascular stents are a class of lifelong micro-devices to support blood vessel for restoring circulation. Despite its remarkable initial outcome, the high rate of long-term mechanical failure remains a major concern. This project will tackle plasticity, fatigue damage and fracture across different length scales. The proposed optimisation is expected to minimise failure, thereby enhancing the longevity and reliability of stent therapy. This will have significant benefits, such as accommodating variations in stents and service conditions for achieving a long-lasting and reliable therapeutical outcome.Read moreRead less
Design of Tough, Durable and Corrosion-resistant Coatings. Coatings are frequently applied to components operating in harsh environments to enhance durability. Often such coatings exhibit low toughness and poor corrosion resistance that leads to premature failure. The aim of this project is to design, characterise and test innovative coatings that exhibit unique architectures based on natural materials such as teeth and nacre. It is envisaged that these coatings will be hard, tough and durable i ....Design of Tough, Durable and Corrosion-resistant Coatings. Coatings are frequently applied to components operating in harsh environments to enhance durability. Often such coatings exhibit low toughness and poor corrosion resistance that leads to premature failure. The aim of this project is to design, characterise and test innovative coatings that exhibit unique architectures based on natural materials such as teeth and nacre. It is envisaged that these coatings will be hard, tough and durable in hostile, corrosive environments, and will thus, transform industries such as manufacturing, mining and offshore oil exploration as well as enhance the lifetime of prosthetic devices.Read moreRead less
Microstructural-Functional Effect of Silver Diammine Fluoride on Apatites. This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue.

This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue. The new biomechanical evidence on the underlying mechanisms, alternative protocols, delivery systems enable to optimise the treatment. The scientific insights into arresting/repairing damage processes will provide critical data for developing minimal intervention protocols for pediatric and geriatric populations.Read moreRead less

The primary goal of this project is to develop mathematical and computational models and techniques that are capable of novel design of functionally graded materials and structures that can dramatically increase the performance and reliability of artificial structures and devices. The applications areas are broad: from lightweight thermal protective coatings used in high-temperature environments to biological hard tissues like bones and teeth. Efficient numerical methods will be developed to overcome difficulties encountered in material properties and loading conditions. The project will provide useful guidelines to design new, intelligent, multi-phase material systems, including biomaterial systems for biomedical applications.Read moreRead less
Structural design of third generation biomaterials. This project will design third generation biomaterials for heart valves, cartilage and bones that guide the formation of new tissue whilst being dissolved inside the human body. As a result, it is anticipated that painful and costly revision surgery will become obsolete. Major benefits will be achieved in paediatric health as implants will have the ability to grow with the child.

This application requests infrastructure funding to ensure the capability of the UTS and UNSW biomedical engineering teams to develop tomorrow's biomedical devices. It will enable research in the field of intelligent medical devices, either non-invasive devices (diabetes monitoring, brain-computer interfaces, home telecare) or those which are fully implanted (heart pumps, bionic eyes). Such biomedical devices will save lives and improve the quality of life of many people. The commercial benefit to Australia flows from the international export of such devices. Based on this approach there will be substantial savings in health care costs, with patients able to resume a better quality of life at home, rather than in institutional care.Read moreRead less
Soft solids rheology and filled elastomeric networks. Elastomeric networks that have imbedded particles are considerably more difficult to model than unfilled networks because the imbedded particles deform the trajectory of the chains. Any treatment must incorporate this dual nature of the network. Our work will address this important issue with particular reference to two important materials - liquid crystalline elastomers and bread dough. We aim to produce an accurate mathematical description ....Soft solids rheology and filled elastomeric networks.
