Electron scattering and transport for plasma-liquid interactions. The project aims to address the emerging technologies associated with the interaction of plasmas with liquids and biological matter, including plasma medicine. The project expects to generate new knowledge on the role of electron-induced processes through the development of complete and accurate sets of microscopic cross-sections for electrons with biomolecules within tissue. This microscopic data will inform new microscopic model ....Electron scattering and transport for plasma-liquid interactions. The project aims to address the emerging technologies associated with the interaction of plasmas with liquids and biological matter, including plasma medicine. The project expects to generate new knowledge on the role of electron-induced processes through the development of complete and accurate sets of microscopic cross-sections for electrons with biomolecules within tissue. This microscopic data will inform new microscopic models for non-equilibrium electron transport in liquids and biological matter, and its coupling to plasmas. The expected outcomes of this project include progress towards the optimisation of safety/efficacy of future generation plasma medicine devices through detailed understanding of plasma-biological tissue interactions.Read moreRead less
Non-equilibrium presolvation electron processes at the gas-liquid interface. The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the pl ....Non-equilibrium presolvation electron processes at the gas-liquid interface. The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the plasma-liquid interface together with fundamental data describing electron interactions with liquids. The project will develop a state of the art presolvation electron transport model informed by world first measurements of electron cross-sections for radicals and liquids and apply it to model plasma electrochemistry processes.Read moreRead less
Positrons in biosystems. This project aims to improve our understanding of the damage processes in Positron Emission Tomography (PET). PET is a widely used medical imaging technique, but there are gaps in our understanding of the underlying interactions, in particular in the case of the radiation damage induced during the process. By using new models incorporating accurate descriptions of interactions processes, verified by experimental measurement, this project will develop a new model of posit ....Positrons in biosystems.

PET is a widely used medical imaging technique, but there are gaps in our understanding of the underlying interactions, in particular in the case of the radiation damage induced during the process. By using new models incorporating accurate descriptions of interactions processes, verified by experimental measurement, this project will develop a new model of positron transport in PET. The project will allow validation of predictions from the model by undertaking experiments in liquid water.Read moreRead less
Positron Nano-Dosimetry: Fundamental Measurements of Positron Interactions and their use in State-of-the-Art Modelling of Positron Transport. This proposal will provide unique experimental and theoretical information on how positrons, the electron antiparticles, interact with matter, in particular with biologically important molecules. This data will be used in a unique set of modelling approaches which will provide, for the first time, an insight into how positrons are transported through gases ....Positron Nano-Dosimetry: Fundamental Measurements of Positron Interactions and their use in State-of-the-Art Modelling of Positron Transport. This proposal will provide unique experimental and theoretical information on how positrons, the electron antiparticles, interact with matter, in particular with biologically important molecules. This data will be used in a unique set of modelling approaches which will provide, for the first time, an insight into how positrons are transported through gases, liquids and ultimately, soft matter. It will thus have important ramifications for diagnostic tools such as Positron Emission Tomography. The fundamental research will also shed light on one of the key 'mysteries' of life - why the biological building blocks of life possess a definite " handedness", or chirality.Read moreRead less
