Novel advances in sub-nanometer imaging. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. Immediately key to further progress in both areas is the ability to characterise the structure of such systems and also their evolution on very short time scales. This research project places Australia at the forefront in this endeavour.
Advanced X-ray investigation of atomic and condensed matter science for Australian industry and scientific research. This project aims to improve the precision and calibration of measurements involving X-rays. This in turn will improve outcomes and instrumentation which utilise X-ray sources to probe structures and properties of advanced materials and biological samples.
Spin detection and control in molecular nanomagnets at surfaces. One fact of computing life is that there's never enough storage. Storing information on single molecules would improve storage density by a factor of 10,000. A promising strategy is to arrange magnetic molecules on a surface, so that their spin can be accessed from one side in read/write operations. While much is known of magnetic molecules in crystals, their behaviour on a surface is still a puzzle.

Storing information on single molecules would improve storage density by a factor of 10,000. A promising strategy is to arrange magnetic molecules on a surface, so that their spin can be accessed from one side in read/write operations. While much is known of magnetic molecules in crystals, their behaviour on a surface is still a puzzle. Using mathematical models and synchrotron experiments, the project will explore which combinations of molecules and surfaces exhibit the best magnetic behaviour. The expected results will be crucial for the development of a new generation of high-capacity and high-performing computers.Read moreRead less

Summary
How antimatter and matter solvates in liquids. This project aims to improve solvation in transport calculations and polar liquids. Solvation, the process of a particle becoming trapped in a liquid, is important in Positron Emission Tomography medical imaging. However, this application can only be described through particle transport simulation, which cannot address solvation. Modelling the dynamical solvation process of the electron and the positron, its antimatter counterpart, is expected to en ....How antimatter and matter solvates in liquids. This project aims to improve solvation in transport calculations and polar liquids. Solvation, the process of a particle becoming trapped in a liquid, is important in Positron Emission Tomography medical imaging. However, this application can only be described through particle transport simulation, which cannot address solvation. Modelling the dynamical solvation process of the electron and the positron, its antimatter counterpart, is expected to enable accurate simulation of medical imaging, acquiring the greatest amount of information for the smallest dosage of radiation to the patient allowing for lower patient radiation doses and more informative scans.Read moreRead less

This project aims to address this question, focussing on three domains of measurement: temperature, time and power. Improving sensors and measurement has been the cornerstone of new physical discoveries, with applications from radio-astronomy to quantum information and navigation. This project aims to build the theoretical foundations for world-beating thermometers, clocks, and photon counters, and to guide experiments in Australia and abroad to bring them into reality.Read moreRead less

Summary
Development and application of super-sensitive spinning quantum sensors. This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth.

This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth. The project's expected outcomes are electro-magnetic sensors with unprecedented sensitivity that could find application in areas ranging from detecting household wiring to locating magnetic anomalies for defence. These outcomes should fill a blind spot of quantum magnetometry, have commercial impact and expand our knowledge of quantum physics in the rotating frame.Read moreRead less

Positrons and molecular electrons interact in new ways as compared to the electrons themselves, thus providing novel chemical possibilities. Australian expertise and the best available elsewhere will be combined to produce important new scientific results in this area and provide major training opportunities for young researchers.
