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

Electron-driven radical chemistry in plasmas for emerging technologies. The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma p ....Electron-driven radical chemistry in plasmas for emerging technologies. The project aims to study electron interactions with the hydroxyl radical (OH). OH is formed in plasmas and atmospheric environments when energetic particles interact with water. Emerging applications of plasmas in wastewater treatment, sterilisation and medicine will be built around OH chemistry. The high intensity of OH spectral emissions has made them useful for remote sensing atmospheric phenomena and diagnosing plasma properties. However, the poor understanding of electron interactions with OH limits our ability to reliably interpret these results. This project therefore aims to experimentally study electron interactions with the hydroxyl radical. The measured values will be applied in simulations that clarify the role of electron–OH interactions in plasma-like environments.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.

Summary
Adapting industrial plasma-processing chemistries through electron collisions to meet emerging technological and environmental requirements. This project involves performing experimental measurements to determine how low-energy electrons interact with highly reactive species, namely free radicals. These interactions play important roles in many industrial applications relating to the manufacture of materials.

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
