Fracture-Resistant Highly Insulating Vacuum Glazing. Vacuum glazing can provide thermal and sound insulation for windows that achieve the benefits of double glazing without the increased thickness by incorporating a vacuum space between two sheets of glass. The gap is maintained by pillars under high compressive stress due to atmospheric pressure. In this project, we will study the effect of pillar designs and materials on the U-value and the mechanical performance of these complex structures.

Vacuum glazing can provide thermal and sound insulation for windows that achieve the benefits of double glazing without the increased thickness by incorporating a vacuum space between two sheets of glass. The gap is maintained by pillars under high compressive stress due to atmospheric pressure. In this project, we will study the effect of pillar designs and materials on the U-value and the mechanical performance of these complex structures. Detailed simulations and measurements of stress distributions in the pillars, edge seals and glass sheets, under static and dynamic loading conditions, will allow us to develop glazing structures with greatly increased mechanical strength.Read moreRead less

The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum ....The Surface Science of Vacuum Glazing. In order to achieve a stable vacuum in evacuated glazing, high temperature baking during evacuation is required. The high temperature processing prevents the use of strengthened glass, such as tempered glass. However, samples made at low temperatures suffer from poor vacuum characteristics, particularly when exposed to UV radiation. In this project, we aim to discover the chemical and physical processes occurring on the glass surface responsible for vacuum degradation. We will use this knowledge to develop a low temperature manufacturing process that can be used with tempered glass and results in a high-quality vacuum, stable over the device service life.Read moreRead less
A versatile optical wavelength and mode switching device for future telecommunication networks. This project will develop a next generation switching device for future fibre optical communication networks that will divide their information among several modes of specialty fibre. This device will be a key component for allowing network operators to move to these novel mode-multiplexed networks in order to overcome the looming capacity crunch.

Optical spectrometers are widely used in science and industry but are large, heavy and expensive. The new chip could enable hand-held devices with performance comparable to large laboratory instruments. It could be revolutionary for colour matching, i.e. determining the colours of materials, offering unprecedented accuracy and robustness to illumination conditions given the size, weight and cost of the device. This technology is anticipated to foster the development of new products using the chip; and make Australia a leader in nano-optics research.Read moreRead less
Enhancing the Understanding and Performance of Passivating TiO2 Coatings for Photovoltaic Devices. Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit. This proj ....Enhancing the Understanding and Performance of Passivating TiO2 Coatings for Photovoltaic Devices. Titanium dioxide (TiO2) has been widely used as an antireflection coating in the silicon (Si) photovoltaics industry as it exhibits excellent optical properties and low deposition cost. However, recently manufacturers have been turning to alternatives such as hydrogenated silicon nitride coatings that exhibit greatly improved electronic properties, but cost 4 - 10 times more to deposit. This project seeks to understand the fundamental limitations behind the poor surface passivation afforded by TiO2 to a Si wafer, and subsequently develop a passivating TiO2 coating that can reduce the cost of electricity generated by Si solar cells.Read moreRead less
Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettab ....Environmentally responsive clean coatings. Nature makes use of a range of fascinating surface properties, such as the leaves of the Lotus plant which stay clean even in dirty environments. In this project we will explore the molecular properties of novel polymer coated surfaces that-similar to some natural surfaces-can adapt to changing environmental stimuli and be resistant to contamination. Specifically, we aim to develop self-cleaning polymer coatings which can reversibly switch from wettable to non-wettable with changing temperature and humidity. These self-cleaning polymer surfaces with environmentally responsive properties will add value to pre-painted steel products and other coatings.Read moreRead less
Improving the wool product. Using mathematical modelling to improve the efficiency of wool scouring. Our aim is to improve the quality of scoured wool by improving the efficiency of wool scouring. Wool scouring is the process of washing greasy wool once it has been removed from the sheep's back. After being rinsed to remove sweat and salt the wool is passed through a scour bowl consisting of settling tanks from which dirty water is periodically expelled.

While current tensions arising from rapid increases in expenditures on pharmaceuticals are likely to become more prominent in future, decision support tools to help policy makers respond to these issues in the most socially and economically efficient way are scarce. Our proposal aims to fill this gap, by gradually extending a prototype model concerning subsidised prescribed pharmaceuticals into a complex economic model of the total Australian pharmaceutical market. The new model will be able to project the impact of policy and other changes affecting all pharmaceuticals, as well as their distributional impact on patients. Expenditures by government and patients, as well as sales by industry, will be separately identified; the effects of the introduction of new drugs monitored; and the benefits of using pharmaceuticals estimated in terms of their impact on the health of Australians.Read moreRead less
