Controlling Anisotropic Growth of Metal Oxide Crystals in Aqueous Solution by Selective Adsorption of Small Molecules. The proposed research will enhance our ability to make both light emitting diodes (LEDs) and piezoelectric actuators from ZnO. LEDs are a high efficiency light source that save energy compared to conventional illumination sources and can be fabricated in thin films.

The proposed research will enhance our ability to make both light emitting diodes (LEDs) and piezoelectric actuators from ZnO. LEDs are a high efficiency light source that save energy compared to conventional illumination sources and can be fabricated in thin films. The proposal is to also bring the technology for device fabrication to Australia where it can ultimately be used to broaden the economic base of the country. The knowledge of crystal growth rate and crystal morphology control can be applied to improvements in the efficiency of alumina production which is already an important contributor to Australian exports.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 resea ....Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles.

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
Flexible dye-sensitised solar cells on polymer substrates. The expected outcomes of the project are the preparation and development of flexible solar cells. The resulting portable and compact solar cells could be incorporated in fabrics opening the solar cell market to the clothing industry.

A new paradigm in near-net-shape advanced ceramic component processing. The raw materials for high performance ceramics (such as alumina and zirconia) are readily available and produced in Australia. Nearly all of these raw materials are exported. The development of processing to make high value added ceramic components from these raw materials will result in greater profit and more jobs for Australians.

This project will develop new coatings for particles, which will allow better control of the properties of particle suspensions. Control of surface properties is also important in the preparation of ceramics and in the preparation of implants and biosensors.
