A high-resolution X-ray microtomography system. 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.

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

The proposed project is aimed at developing advanced orthopaedic implants (intramedullary nails and associated locking screws) commonly used for bone fracture repair. These new generation metallic implants will be developed using a comprehensive research approach centred on physico-chemical and mechanical properties investigations. A new generation of intramedullary nailing systems with superior design and mechanical properties (small diameter and high strength) and improved bone fixation is the key expected outcome. The knowledge generated in the project is expected to lead to the growth of the Industry Partner (Austofix). Training of a world class researcher in the multidisciplinary field of biomaterials will be an additional outcome.Read moreRead less
Attachment of Growth Factors to Pure, Plasma Modified and Coated Titanium Substrates. Titanium and its alloys are routinely used as medical and dental implants. Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone.

Despite coating with hydroxyapatite, a material well known to improve implant fixation, many such implants fail because of lack of strong integration with bone. This proposal aims at achieving long-term stability of titanium implants through their surface modification and subsequent attachment of growth factors. The use of latter has already been shown to help bone-implant integration. Successful project implementation will provide titanium implant surfaces that will help achieve speedier and improved implant fixation with long-term stability. Knowledge, expertise and techniques developed will help the industry partner expanding its research base and business and generating wealth in Australia. Training of world-class research students in the emerging field of biotechnology will be another major outcome.Read moreRead less

Summary
Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotr ....Synchrotron-based modelling of the deformation and fracture mechanism in normal and osteoporotic femurs under multiaxial loading cycles. The femur is a light-weight structure designed to best perform in life. However, the complex tissue architecture, microstructural organisation and its complex loading regimens make it difficult to understand how the femur can deform and fracture. This project studies femoral fractures by modelling the proximal femur with a micrometric level of detail. Synchrotron femur images are taken in loaded and unloaded conditions. Cortical strain and fracture are measured, replicating possible multiaxial loads. Micro finite-element models will be used to study the contribution that the bone tissue architecture, tissue structure and activity types make to the fracture. The resulting knowledge will have future orthopaedic applications.Read moreRead less
