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.

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

Hydrogen is a clean non-polluting fuel. Production of hydrogen (Solar-Hydrogen) directly from water and sunlight is a very appealing renewable energy technology. The key requirement to allow this technology to be adopted is finding an electrically suitable material. This research program takes an innovative approach by combining state of the art computational techniques to engineer advanced ceramics having sophisticated electrical signatures. These ceramics will be synthesized in a partner experimental program to gauge their efficiencies for hydrogen production. The program will provide the foundation for a renewable energy technology that will provide clean energy and energy independence for Australia.Read moreRead less
New dielectric materials: Improving storage density of high temperature multilayer ceramic capacitors to sustainably meet future energy demands. Electrical energy generation from renewable sources, such as solar, wind and geothermal, provide enormous potential for meeting future energy demands. However, the ability to store and control this energy for miniaturisation and modularisation in applications requiring a wide temperature usage range is a limiting factor that needs to be addressed.

Electrical energy generation from renewable sources, such as solar, wind and geothermal, provide enormous potential for meeting future energy demands. However, the ability to store and control this energy for miniaturisation and modularisation in applications requiring a wide temperature usage range is a limiting factor that needs to be addressed. This project aims to develop new bismuth-based lead-free dielectric materials for improving the storage density of high temperature multilayer ceramic capacitors for sustainable applications in the energy and vehicle industries, where high temperature stability and high volumetric efficiency are crucial.Read moreRead less
Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but the ....Increase in Photocatalytic Activity of TiO2 through Intervalence Charge Transfer. Titanium dioxide (TiO2) has many proposed and realised applications in energy and the environment. The main problem that has hindered development and commercialisation of devices using TiO2 is its low photocatalytic activity, which results from its poor absorption of visible and infrared light. Most researchers modify the properties of TiO2 by conventional electrochemical methods to improve its performance but these attempts have been of limited success. The present research involves a completely new approach to the problem, which is based on the method used in the heat treatment of sapphire to improve its colour. This approach uses a phenomenon involving the modification of the optical properties to improve its absorption of light.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.

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
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.
Enhanced electro-active properties in polycrystalline ceramics: a multi-length-scale approach. Electro-active materials are used in a wide range of devices including ultrasound imaging equipment and nano-positioning systems.

Structurally designed catalysts for high-performance natural gas reforming. This project aims to develop a new class of highly stable catalysts with specially designed physical and chemical structures that can be used in high temperature chemical processes. These catalysts can potentially be used for the reforming of natural gas to produce the synthesis gas, which can then be used to produce liquid fuels and chemicals.

Doping the zirconia with metals such as yttrium and aluminium can produce advanced ceramics, with applications in areas such as solid oxide fuel cells and oxygen sensors. The aim of this project is to improve the fundamental understanding of the chemistry in the initial processing steps, so that the process can be readily modified to produce new doped zirconia ceramics, without the extensive empirical process development currently required. The resulting ability to quickly produce new compositions on a commercial scale will put this industry in a world-leading position, dramatically increasing the added value of the zirconia products.Read moreRead less
