Dark-field: A new kind of x-ray imaging. This project aims to develop new x-ray imaging capabilities that look inside an object and map out those details that are too small to be seen directly, by extracting the dark-field which is produced as x-ray light scatters. Dark-field images can reveal tiny cracks in manufactured parts, discover powdered explosives or drugs during security screening, and detect changes in the size of the many tiny air sacs in the lungs. Expected outcomes of this project ....Dark-field: A new kind of x-ray imaging.

Expected outcomes of this project include new instruments and methods of analysis that will allow x-ray dark-field imaging to be quantitative and widely adopted. These methods should benefit non-invasive multi-scale imaging at the Australian Synchrotron and equip x-ray imaging in industry, security and healthcare.Read moreRead less

The project aims to measure mechanics at the cellular level using a combination of optical tweezers for measurement of nano-scale environment around/inside cells and light-sheet microscopy for imaging. The project expects to generate new knowledge about movement of cells through their environment, relating to collective behaviour which is of importance in understanding infections and formation of biofilms. Expected outcomes include deepened understanding of an enigmatic process conserved from amoebae to humans, by which cells ‘drink and eat’ by ‘gulping’ fluid and supplement their nutrient intake by degrading proteins and cell debris. It will generate new knowledge of these processes to better understand how mechanics affects cellular life.Read moreRead less

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 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
