This project aims to reveal the 3D nanostructure of disordered matter with x-rays for the first time. Existing x-ray scattering techniques for disordered structures currently provide limited, one-dimensional information only. The expected outcomes of the project include an enhanced new capability for the Australian Synchrotron and international x-ray laser facilities, and new insights into the microscopic origins of the properties of liquids and biological membranes. This should benefit research areas that use x-ray scattering to probe the nanostructure of materials for diverse applications such as nanotechnology, fuel cells and drug design.Read moreRead less
Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signal ....Enhancing gravitational wave detector sensitivity and bandwidth for astronomy. This project aims to create small optomechanical devices that amplify the signals in gravitational wave detectors, increasing their sensitivity, especially for higher frequency signals. Calibrated against the 2015 first detection of gravitational waves from black hole mergers, this technology could allow humanity to listen to black holes merging up to 30 times every day, while giving much greater sensitivity to signals from smaller black holes and neutron stars. The new technology, which uses nano-scale suspended tiny mirrors controlled by laser light, is likely to have applications in making sensors and quantum devices for advanced instrumentation, improve mineral exploration and measure tiny electromagnetic signals.Read moreRead less

This project aims to develop new X-ray imaging methods that capture multiple next-generation image modalities at an unprecedented range of length and time scales. While conventional X-ray imaging is routinely used in medicine and industry, it can only visualise high-density materials like bone. To reveal low-density objects like biological soft tissue and microstructure like tiny cracks, the project plans to extract two complementary image modalities using a robust setup that does not rely on large-scale facilities. Significant benefits from the developed methods are expected for leading-edge research in fields including biomedicine, materials science and palaeontology, and industries such as security, medical diagnostics and manufacturing.Read moreRead less

This project aims to investigate how sound waves exert forces on objects, and how these forces can be controlled by artificially engineered structures known as acoustic metamaterials. The project is expected to lead to a new understanding of acoustic radiation forces, and how they can be efficiently manipulated with high resolution. The expected outcome is a new capability for the measurement of delicate mechanical structures, which avoids the cost, complexity and side-effects of existing systems. This should benefit many high-tech areas, including inflatable space structures, micro-mechanical sensors and actuators and precise optical components, as well as biological areas such as the study of insect flight and communication.Read moreRead less

These facilities expect to increase the event rate of gravitational wave signals by a factor of 125. This should lead to daily detections and the observation of new sources of gravitational waves. Given that only 5% of the universe is detectable by telescopes, the impact of gravitational wave detections on our understanding of the universe is inestimable. Australian partnership intends to enable our physicists and astronomers to be at the vanguard of this brand new field and inspire a new generation to study the physical sciences.Read moreRead less
