Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductil ....Crack Propagation within Graded Interfaces. Functionally graded interfaces are a technologically new way of joining materials in a wide range of biomedical and industrial applications. The reduction in the interfacial stresses resulting from the graded interface increases the structural integrity of the component, however, existing models do not fully address issues of plasticity and cyclic fatigue to their fracture. The intention of this study is to investigate how modifications to the ductile reinforcement phase and how the cyclic loading influence crack extension within a graded interface. These results will assist in future design and prediction of the in-service lifetime of components containing gradient interfaces.Read moreRead less
Modification of optical properties of photocatalytic titania. The aim of the project is to capitalise on and optimise the recently discovered successful modification of the optical properties of titanium oxide (TiO2), such that efficient solar splitting of water is possible. TiO2 photocatalysts of adequate efficiency will be implemented as photoanodes in photoelectrochemical cells capable of large-scale production of hydrogen.

Summary
Ultra-high resolution and advanced analytical scanning electron microscope facility. This scanning electron microscope facility will form an essential part of characterising a broad range of material types, from nanometre sized particles through to cells and their interactions.
Design of hollow nanoparticles of titania for the sustainable production of hydrogen from water using sunlight. Hydrogen is a clean and non-polluting fuel that is the natural and sustainable replacement for greenhouse gas emitting fossil fuels. Because of its abundant sunlight and vast titanium reserves (the world's largest) Australia is especially well-placed to develop the technology of producing hydrogen directly from water and sunlight using a titanium dioxide photo-anode. This research, whi ....Design of hollow nanoparticles of titania for the sustainable production of hydrogen from water using sunlight. Hydrogen is a clean and non-polluting fuel that is the natural and sustainable replacement for greenhouse gas emitting fossil fuels. Because of its abundant sunlight and vast titanium reserves (the world's largest) Australia is especially well-placed to develop the technology of producing hydrogen directly from water and sunlight using a titanium dioxide photo-anode. This research, which consists of computational and experimental parts, is focused on laying the scientific foundation for that technology to be commercially viable. The national and community benefits are the availability of an inexpensive, limitless and clean fuel, reduction in reliance on energy imports, reduction in greenhouse gas emissions and resultant global warming.Read moreRead less

Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pi ....Enhanced pigment weathering resistance by coating with high dielectric ceramic. The partner company, Tiwest, based in Western Australia, is a major contributor to the economy, and earns more than $A400m annually in exports. It is the only company in the world that mines, separates, refines and manufactures titania products, including pigments, in one region. The current post-titania particle formation wet-coating process, however, presents a major capital and recurrent cost and necessitates a pigment regrind stage. The research will investigate the development of a highly durable dry-coated pigment utilising a novel high dielectric coating. This development has the potential to ensure the partner company's future competitiveness through reduced processing costs and improved product performance.Read moreRead less

Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape.

Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings. The research aims to identify the fundamental link between particle network strength and structure and the fracture of wet powder bodies. The microscopic mechanisms that control the behaviour will be investigated with a particular focus on toughening mechanisms including the influence of plasticity.Read moreRead less
