This project aims to achieve safer, faster, and cheaper 3D X-ray imaging through a technique known as ghost imaging. X-ray imaging provides valuable information about internal structures, however, X-rays are carcinogenic and exposure (or dose) should be limited. Ghost imaging is an unconventional technique developed with visible light that has many potential benefits over conventional imaging. This research group are world leaders in ghost imaging and expect to develop software and hardware techniques to realise its potential and extend it to ghost tomography. The focus of this project is on reducing cancer risk in medical imaging, and allowing real-time quality control for 3D printing in safety-critical industries such as aerospace.Read moreRead less
Nanometrology of laser-trapped airborne particles. This project aims to develop a new concept of touch-free measuring of physical characteristics of nanoparticles using specially designed optical vortex beams. The new concept will be of direct importance in developing new nanotechnologies demanding ever-increasing purity of every element in the industrial environment and production processes.
Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history. Techniques have been developed for measuring all four sulfur isotopes, including the low abundance sulfur-36 (0.02 per cent) to 0.2 per mil, in situ for sulfides. This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on proces ....Sulfur isotope fractionations in Earth evolution. Sulfur isotopes provide a unique window into the major events in Earth's history.

This project will make innovative technological developments to the counting system to extend this capability to the lower count rates obtained from sulfates. This will open windows for research on processes occurring in the early solar system, atmospheric and hydrologic conditions in the Archean, ore-forming processes, and evolution of life on Earth.

Exposure dating with manganese-53, neon-21 and beryllium-10: a new toolkit for studying long-term landscape evolution. Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known.

Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

Global Gravitational Wave Astronomy. To listen to the universe with gravitational waves needs a global array of gravitational wave observatories, and one of these must be in the southern hemisphere - in Australia. By definitively answering outstanding questions about an Australian gravitational wave observatory - Where should it be? How sensitive?

To listen to the universe with gravitational waves needs a global array of gravitational wave observatories, and one of these must be in the southern hemisphere - in Australia. By definitively answering outstanding questions about an Australian gravitational wave observatory - Where should it be? How sensitive? What astronomy will it aid? - we make the case for the international community to help build this observatory, investing hundreds of millions of dollars in rural Australia and keeping Australia on the cutting edge of all branches of astronomy. As a flagship client of advanced data GRID technologies, we will also shape the growth of Australian knowledge of, and infrastructure for, next-generation communications technologies.Read moreRead less
Role of water in earth and planetary evolution. This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth.

This project aims to understand the role of water in the building of our solar system, Mars and Earth. Surprisingly little is known about key issues surrounding the origin of water and its subsequent recycling on Earth. This project will use new techniques for measuring low abundances of water along with oxygen isotopes, to measure water abundances and oxygen isotopes in meteorites and terrestrial rocks to establish how water was delivered to Earth and to understand how water is geologically recycled. This is expected to have direct bearing on where and how Earth's water originated, how water is retained in mantle and crustal minerals and it will have broad implications for understanding volcanic hazards and formation of ore deposits. This will lead to a new capability for combined water and oxygen isotope analysis in Australian geoscience leading to technological development and commercialisation of instrumentation.Read moreRead less
Surface adsorption, repulsion and attraction: A new experimental approach to surface forces. The ability to understand and manipulate the stability of finely dispersed particles (colloids) in water is essential to modern living. It is necessary in processes as diverse as water purification, minerals separation, food and paper production. The behaviour of the colloidal system can often be understood in terms of the interaction between the dispersed particles.

The ability to understand and manipulate the stability of finely dispersed particles (colloids) in water is essential to modern living. It is necessary in processes as diverse as water purification, minerals separation, food and paper production. The behaviour of the colloidal system can often be understood in terms of the interaction between the dispersed particles. This project aims to improve our ability to predict the nature of the interaction between dispersed particles, through an understanding of the events at a particle surface during a collision with another particle. This will enable us to better understand and control real colloidal systems.Read moreRead less
