This project aims to address a big challenge in nanophotonics by developing revolutionary methods for efficient chiral sensing of molecules without the need for spectrometry, frequency scanning, or moving mechanical parts, and to enhance chiroptical signals a hundredfold with the help of metasurface structures. Resonant metasurfaces are arrays of engineered dielectric nanoparticles with extraordinary characteristics, and they would allow to overcome current limitations of chiral sensing analytical tools. Detecting chiral molecules in low concentrations is crucially important to many fields of biology, chemistry, and pharmacy, as well as to the food and cosmetics industries, constituting a market of tens of billions of dollars.Read moreRead less
Spatiotemporal dynamics and analysis of functional magnetic resonance imaging. Functional magnetic resonance imaging (fMRI) produces signals generated by brain activity in fine detail, but links between activity and images are poorly understood, posing a barrier to full use of the technology. Predictions from our new theory of such links will be made, tested experimentally and used to improve fMRI and discover new phenomena.
Realisation of an ultra-stable local oscillator using an ultra-low vibration pulse-tube cryocooler. This project will complete the development of a new type of ultra-low-noise ultra-stable microwave oscillator cooled with an ultra-low vibration cryostat and cryocooler. The resulting oscillator will have wide application, but especially to atomic fountain clocks and to very high frequency Very Long Baseline Interferometry (VLBI) radio astronomy.
Probing Anaesthetic Effects with New Functional Imaging Paradigms. This project seeks new insights into the effects of anaesthetics on brain function and repair. Anaesthesia is used in small-animal imaging to immobilise the animal, but in many cases the anaesthesia itself affects the neurophysiological parameters under study. It has also been shown that many anaesthetics enhance recovery after brain injury in small animals. This project plans to exploit a novel functional brain-imaging technique ....Probing Anaesthetic Effects with New Functional Imaging Paradigms. This project seeks new insights into the effects of anaesthetics on brain function and repair. Anaesthesia is used in small-animal imaging to immobilise the animal, but in many cases the anaesthesia itself affects the neurophysiological parameters under study. It has also been shown that many anaesthetics enhance recovery after brain injury in small animals. This project plans to exploit a novel functional brain-imaging technique for conscious animals to gain new insights into the effects of anaesthetics on brain function and recovery from injury. The knowledge gained is expected to improve knowledge of anaesthetic action, guide future anaesthetic use in small animal imaging to improve the accuracy of image-derived research data, and help to clarify how anaesthetics confer neuroprotective effects in brain injury.Read moreRead less

Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations ....Dual nanoparticles to distinguish between right and left biomolecules. This project aims to enhance the sensitivity of optical activity to ultralow molecular concentration samples. Optical activity is a commercially available technique used to distinguish chemically identical and morphologically different biomolecules (enantiomers). Unlike other scattering techniques, near-field enhancing of optical activity has not been achieved, thus limiting these measurements to high molecular concentrations. There is evidence indicating that optical activity can be enhanced using dual nanoparticles (ie small particles with the same response to electric and magnetic fields). This project aims to advance our understanding of these dual nanoparticles and experimentally implement their use to enhance optical activity.Read moreRead less

Summary
Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical p ....Brillouin microscopy for high-speed imaging of rigidity within cells. This project aims to improve the sensitivity and speed of Brillouin microscopes. Brillouin microscopes use light to measure the stiffness of samples in 3D without requiring physical access, allowing their use in inaccessible locations such as the interior of cells or within intact tissue. However, Brillouin microscopes are too slow to be used in most research. This project introduces a new approach based on different optical physics that is expected to enable faster and more precise imaging. The microscope will be used to study the movement of amoeba, where it is expected to reveal the controlled stiffening and fluidising of the different regions of protoplasm believed to underlie the cell mobility.Read moreRead less

This project aims to give experimental answers to long existing theoretical questions about the origins and nature of dark matter. Dark matter is a fundamental component of the universe, yet the nature of its composition is still unknown. There is growing evidence that dark matter is comprised of low mass and weakly interacting particles. By developing ultra-precise measurement tools and new techniques, this project aims to perform a stringent and comprehensive new laboratory search for ultra-light dark matter particles, over likely mass ranges not yet searched. The knowledge gained will provide economic benefits through commercialisation and stimulation of new research and development, and to defence through applications in radar, communications and sensing.Read moreRead less

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
