Magneto-optical materials have a wide range of potential applications in consumer products, telecommunications and defence. Nanotechnologies based on these materials offer an even broader range of emerging applications. Understanding and participating in the development of magneto-optic technologies will therefore be critical to maintaining Australia's knowledge base and expertise in future technological advances. Given the early stages of development of these technologies, Australia's expertise in material science and the patent rights held by Australian companies in this area, Australia has the opportunity to make major contributions to this field, and the potential to capitalise on the application of these technologies in niche markets.Read moreRead less

Cyclic Fatigue Mechanisms in New Lead-Free Piezoelectric Ceramics. Piezoceramics are an important component in many items in modern day Australian life. However, they present a growing environmental concern, particularly for disposal, because they contain lead oxide and must often be disposed of prematurely due to component failure. Furthermore, many key Australian industries manufacture and use piezoceramics in fields ranging from mineral exploration, to imaging to biomedical devices. This proj ....Cyclic Fatigue Mechanisms in New Lead-Free Piezoelectric Ceramics. Piezoceramics are an important component in many items in modern day Australian life.

Ti3SiC2 belongs to a large group of ternary carbides that exhibit an unique combination of high temperature ceramic properties, with the electrical and thermal conductivity of metals. A great number of potential applications have been identified, but are currently limited by residual intermediate compounds, that degrade the properties. This project will use crystal structure similarities between TiCx and Ti3SiC2 to engineer a crystalline precursor, Ti3C2, which circumvents intermediate compound formation. This innovative methodology will also reduce the cost and time of fabrication. Advanced in-situ neutron diffraction techniques will be used to quantify the synthesis kinetics and optimize the method.Read moreRead less
