CASE STUDY 1 – NANOCRYSTALLINE ZINC OXIDE

science.uts.edu.au

ZnO has a very wide range of industrial and consumer applications Some requirements are for nanocrystalline particles Together with multi- national client we developed new methods to manufacture such materials

CASE STUDY 2 – COATINGS FOR ENHANCED RADIATIVE HEAT TRANSFER There is a special range of infrared wavelengths through which the sky is especially transparent By manipulating the emissivity of a coating material as a function of wavelength, it becomes possible to have coatings that ‘pump’ heat out into the sky. Significant cooling of a roof or building can be achieved in this way. We have had several industrial consultancies on this topic.

CASE STUDY 3 – MATHEMATICAL MODELLING OF FORMATION OF MESOPOROUS METALLIC CATALYSTS Nanoporous sponges of gold, platinum and silver can be made by de- alloying a precursor alloy. These have potential applications as catalysts, sensor electrodes, SERS substrates, spectrally-selective optical coatings, and actuators. We have worked extensively in this area, by making, characterizing and modelling these

• sponges. We have had an

industry-funded project on this topic.

CASE STUDY 4. ELECTROMAGNETIC SIMULATIONS Effect of surface roughness on the reflectance of Ag-Al mirrors. (Surface enhanced Raman substrates, mirrors for LEDs, spectrally- selective coatings, plasmonic devices) Ab initio modelling and experimental verification:

1. Calc optical properties by Density Functional theory then check against experiments

• 2. Construct high resolution

geometric models of surface then determine effect of light.
