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
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. This project will determine the most fundamental mechanisms at work in these materials allowing for the optimisation of high-performance and environmentally friendly electro-active devices for future industries.
Development of conductive buffer layers for RABiTS-based coated conductors. YBCO coated conductor has already been identified and developed as far as second generation HTS wire in power applications. Major advances have been made in the last 10 years in coated conductor development mainly in all aspects: substrate, buffer layer and YBCO layer. The research on conductive buffers layer will improve and expand the R&D on coated conductor in Australia. On the economic side, dramatic advantages and s ....Development of conductive buffer layers for RABiTS-based coated conductors. YBCO coated conductor has already been identified and developed as far as second generation HTS wire in power applications. Major advances have been made in the last 10 years in coated conductor development mainly in all aspects: substrate, buffer layer and YBCO layer. The research on conductive buffers layer will improve and expand the R&D on coated conductor in Australia. On the economic side, dramatic advantages and savings could be achieved if the coated conductors can be put to use. Superconductivity can have a significant role in deregulated electricity markets and in lessening CO2 emissions and other environmental impacts.Read moreRead less
