Design Of Practical Passive Cooling Radiators Utilising Spectrally Selective Covers And Surfaces. Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance ....Design Of Practical Passive Cooling Radiators Utilising Spectrally Selective Covers And Surfaces. Radiative cooling offers a means to cool buildings sustainably without complex and costly heat pumps or air conditioners. Units similar to solar panels can be designed with surfaces which radiate mostly into the 8 - 12 micron atmospheric window, which has a radiance much less than for other wavelengths. Commercial development has been limited by problems associated with the degradation, performance or cost of radiator surfaces. This project seeks to improve both performance and durability with innovative use of alternative materials and sputtered coatings suitable for mass manufacture, and to test the outdoor performance of laboratory produced radiative plates.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

This project aims to synthesise highly active electrochemical catalysts of two-dimensional (2D) inorganic nanostructure for hydrogen evolution reaction (HER). The electrocatalysis of water to produce hydrogen gas could generate clean energy, but the platinum catalyst’s cost and low activity make it impractical. This project will develop 2D inorganic nanosheets with tuneable pores and electronic band structures, hybridised with organic and/or inorganic semiconductor nanomaterials for HER, and use density functional theory calculation to investigate these hybridised nanosheets’ mechanisms for HER. These highly efficient and low-cost catalysts are expected to generate clean energy and create opportunities for Australian industries.Read moreRead less
