Development of inert gas ion beams for fabrication of nano-structures. This project will develop a high brightness, high density ion beam for reactive fabrication of structures with dimensions of the order of and less than 100 nano-metres. Present systems use liquid metal ion sources which can pollute the substrates being fabricated. Use of inert gas ions will overcome this problem and lead to a new type of ion source to replace the older systems. Added advantages include significantly increased ....Development of inert gas ion beams for fabrication of nano-structures.

Present systems use liquid metal ion sources which can pollute the substrates being fabricated. Use of inert gas ions will overcome this problem and lead to a new type of ion source to replace the older systems. Added advantages include significantly increased lifetime much higher reproducibility. Our commercial collaborator, FEI Company, estimate the world market as being $US100,000,000 and will actively promote this technology worldwide when it is fully developed.Read moreRead less

Pathologies of the cardiovascular system arising from heart diseases make a major contribution to morbidity and mortality in the Australian community. This project will provide new diagnostic modalities based on advanced noninvasive bioinstrumentation, signal processing and model-based analytical methods to identify early signs of developing disease or the acute exacerbation of existing disease. The impact of these new technologies on the early diagnosis and improved triaging of patients in emergency departments is potentially profound and could result in improved healthcare outcomes for the patients and reduced admissions to hospital as well as the development of a substantial international market.Read moreRead less
Residential Air Conditioning, Comfort and Demand Response in Australia. Rapid growth in residential air conditioning (AC) ownership will potentially undermine national energy efficiency and greenhouse reduction targets. Furthermore, residential AC is placing a strain on the national electricity system, especially during heat waves when electricity demand peaks. These AC-driven peak loads occur occasionally each summer, but increasing grid capacity to meet them represents a grossly inefficient in ....Residential Air Conditioning, Comfort and Demand Response in Australia. Rapid growth in residential air conditioning (AC) ownership will potentially undermine national energy efficiency and greenhouse reduction targets. Furthermore, residential AC is placing a strain on the national electricity system, especially during heat waves when electricity demand peaks. These AC-driven peak loads occur occasionally each summer, but increasing grid capacity to meet them represents a grossly inefficient infrastructure investment. This project will generate Australia's most comprehensive data set on exactly how, when, where, and why residential AC systems are being used. The outcomes will provide a solid platform on which national electricity demand management and AC greenhouse-gas mitigation strategies can be designed.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
Noise-free Cryogenic Wavefront Sensing. This project aims to optimise the prototype adaptive optics technology for the Giant Magellan Telescope (GMT) by leveraging past investment in adaptive optics instrumentation and shortwave infrared detector systems. This project expects to generate significant improvements in GMT performance, with ten times greater image resolution than the Hubble Space Telescope and current estimates of >90% sky coverage, compared with ~50% coverage for current technology ....Noise-free Cryogenic Wavefront Sensing. This project aims to optimise the prototype adaptive optics technology for the Giant Magellan Telescope (GMT) by leveraging past investment in adaptive optics instrumentation and shortwave infrared detector systems. This project expects to generate significant improvements in GMT performance, with ten times greater image resolution than the Hubble Space Telescope and current estimates of >90% sky coverage, compared with ~50% coverage for current technology. Expected outcomes of this project include the development of a highly trained workforce and continued international collaboration in the field of high-technology sensor systems. This contribution to the GMT will provide significant benefits—it will change the way we view the Universe.Read moreRead less
A Laser Guide Star using a High Power, Synchronously Pumped Optical Parametric Oscillators. We will develop a novel high power source of 589nm coherent (laser) light to be used to create a laser guide star by exciting sodium atoms in the earth's upper atmosphere (the mesosphere). This is needed to determine the distortion caused by the atmosphere on an optical beam propagating through it and generate the information needed to correct those distortions using an adaptive optics telescope.

This project is to create a significantly better technology for exploration of oil and gas reserves under the ocean. Based on lasers and fibre optics, it leverages Australia's prodigious photonics expertise and couples it with Australia's established and well-regarded resource industry. Successful completion will enable better utilization of this country's natural resources, in particular oil and gas reserves, whilst also creating a high technology export, given the size of the world marine survey market (US$4 billion). Better energy exploration technologies are vital to Australia and, indeed the world, as energy supply dwindles and the increased energy costs begin to impact negatively on economic growth.Read moreRead less
Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the fi ....Short-pulse laser cleaning for Australian heritage conservation. Conserving heritage objects is a demanding discipline, requiring a suite of techniques for different problems. Overseas, laser cleaning using long pulse techniques leaves microscopic damage as discrete chunks of material are removed, and is unsuitable for many materials. We have developed a short pulse laser process which can remove material molecule-by-molecule in a controlled fashion, and which can be readily halted once the final finish is achieved. We will research this technique for application to unique Australian heritage materials that are important to the specific conservation needs of the Australian War Memorial, the RAAF, Navy and Army Museums, Artlab Australia, and the Art Gallery of NSW.Read moreRead less
