Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on ....Real-time imaging of crystal strengthening mechanisms in metals. The strength limit of a metal is marked by rapid motion of crystalline defects. The associated speeds can locally approach that of sound. To probe the associated mechanisms clearly requires both spatial and temporal resolution. We propose to create a new bulk x-ray technique with an unprecedented combination of temporal and spatial resolution. We plan to exploit the technique to mediate a step change in modelling strength based on twinning. The formation of crystalline twins is known to dictate the strength of the light metal magnesium. A fuller understanding of the effect of twinning on strength in this metal will provide much needed confidence to implement it more widely in energy saving applications.Read moreRead less

Characterisation of the beneficial vs toxic forms of selenium in the diet. This project aims to examine how dietary selenium is converted into essential proteins and beneficial compounds that mitigate against a broad range of human diseases; or alternatively, into toxic molecules. Cutting-edge methodologies should resolve significant unknowns in selenium metabolism, to provide definitive dietary guidelines and to explore how selenium can treat and protect against disease.

Quantum thermalisation: a new framework for nuclear collisions. This project aims to quantify and model the processes that lead to quantum thermalisation in nuclear collisions. Thermalisation is critical to the synthesis of new superheavy elements, production of medical isotopes, and creation of heavy elements in the cosmos. Yet quantum thermalisation in nuclear systems is not understood, causing models to be wrong by up to a factor of 100. This project will determine the routes to thermalisatio ....Quantum thermalisation: a new framework for nuclear collisions.

This project aims to develop new brain imaging technology that adapts to and corrects for the motion of a responsive, freely moving mouse. Current technology requires the subject to be unconscious, precluding the use of imaging to study signalling pathways activated by external stimuli during cognitive and behavioural tasks. By harnessing new radiation detector, motion tracking and computational technologies, the project expects to bridge this technology gap and provide significant technical and conceptual advances in the field. This will provide important benefits, such as equipping neuroscientists with new tools to answer fundamental questions about how the mammalian brain regulates behavioural adaptation to a changing environment.Read moreRead less
