Simulation and characterisation of opto-thermionic cooling devices. Opto-thermionic devices combine thermionic emission and laser cooling to achieve the maximum cooling power and highest thermal efficiency. These devices are ultra small, very reliable and fully integrable. Many important problems need to be solved to improve the performance of this new class of solid-state cooling devices. One is to understand and manipulate the electron-hole radiative recombination and minimize the Auger proces ....Simulation and characterisation of opto-thermionic cooling devices. Opto-thermionic devices combine thermionic emission and laser cooling to achieve the maximum cooling power and highest thermal efficiency. These devices are ultra small, very reliable and fully integrable. Many important problems need to be solved to improve the performance of this new class of solid-state cooling devices. One is to understand and manipulate the electron-hole radiative recombination and minimize the Auger process in reduced dimensionality devices such as quantum wells. Researchers at Wollongong and Lund will collaborate on theoretical analysis, computer simulation and electrical/optical measurements to solve this problem.Read moreRead less
Development of Solid-state cooling chips. The performance of modern electronic, microelectronic, optoelectronic and photonic devices improves as they are cooled. We aim to develop semiconductor cooling elements that can be directly integrated into existing circuits and devices. The new solid-state cooling elements will be reliable, robust, scalable and operate in any orientation. The proposed international collaboration combines the expertise of the Chinese Academy of Science in device fabricat ....Development of Solid-state cooling chips.

We aim to develop semiconductor cooling elements that can be directly integrated into existing circuits and devices. The new solid-state cooling elements will be reliable, robust, scalable and operate in any orientation. The proposed international collaboration combines the expertise of the Chinese Academy of Science in device fabrication with the expertise of the University of Wollongong in device characterisation and modelling. The outcome of this research has the potential to revolutionize cooling of diverse electronic systems, from computer motherboards to mobile phones.Read moreRead less
Development of ultrastable high flux hydrophobic pervaporation membranes for organic separations. Perfluorinated glassy polymers (Teflons AF) as membrane materials are endowed with unique fluxes and excellent stability when in contact with various liquid organic mixtures. However, they have never been explored as membrane materials for pervaporation. The aims of this project are therefore to evaluate the applicability of composite membranes based on amorphous Teflons AF to the separation of orga ....Development of ultrastable high flux hydrophobic pervaporation membranes for organic separations. Perfluorinated glassy polymers (Teflons AF) as membrane materials are endowed with unique fluxes and excellent stability when in contact with various liquid organic mixtures. However, they have never been explored as membrane materials for pervaporation. The aims of this project are therefore to evaluate the applicability of composite membranes based on amorphous Teflons AF to the separation of organic mixtures and the removal of organic pollutants from water. The outcomes of this project will be the development of novel environmentally friendly processes in the petrochemical and biotechnology industries as well as ecologically efficient methods of waste water treatment.Read moreRead less
Novel hybrid agricultural-byproduct/synthetic materials. The French partners have developed a method of converting low-value agricultural by-products into commodity plastics; however, the results are too water-sensitive to be useful. This project is to develop the science for grafting water-resistant moieties to this product, using mechanistically-based techniques developed by the Sydney group. The outcome would be technology for making useful materials from agricultural by-products that are cur ....Novel hybrid agricultural-byproduct/synthetic materials.

This project is to develop the science for grafting water-resistant moieties to this product, using mechanistically-based techniques developed by the Sydney group. The outcome would be technology for making useful materials from agricultural by-products that are currently of very low value in Australia.Read moreRead less
