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
Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in sit ....Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in situ material repair to extend device lifetime, and modulate plasma properties to increase thruster efficiency for a given task. These benefits enable reliable propulsion platforms for massive communication and observation satellite networks and deep space exploration.Read moreRead less
Plasma-assisted on-surface assembly for hydrogen production and beyond. This project aims to discover how to catalyse the formation and control the structure of functional materials with atomic precision using plasmas. New mechanisms of ultra-fast, plasma-catalytic on-surface nanoasembly will translate into energy-efficient, scalable digital fabrication of subnano-cluster and single-atomic-site catalysts over large 3D surface areas, tailored for advanced electrocatalysis. The outcomes including ....Plasma-assisted on-surface assembly for hydrogen production and beyond.

New mechanisms of ultra-fast, plasma-catalytic on-surface nanoasembly will translate into energy-efficient, scalable digital fabrication of subnano-cluster and single-atomic-site catalysts over large 3D surface areas, tailored for advanced electrocatalysis. The outcomes including new concepts and insights into synergistic action of plasmas and solid surfaces will bridge atomic-scale materials formation and digital fabrication at industrial scales. The benefits including the new nanofabrication platform and clean energy will go beyond the demands of digital manufacturing and hydrogen economy. Read moreRead less

Summary
Detecting Key Concepts from Low-Quality Data for Better Decision. The project aims to develop data analytics techniques that aid better decision making in high-stake scenarios when data are less-trustable. While data-aided decision making has been widely used, less-trustable data may significantly distort the decisions made and hurt people impacted by these decisions. The outcome of this project expects to be a series of techniques covering data understanding and enhancement, model development a ....Detecting Key Concepts from Low-Quality Data for Better Decision. The project aims to develop data analytics techniques that aid better decision making in high-stake scenarios when data are less-trustable. While data-aided decision making has been widely used, less-trustable data may significantly distort the decisions made and hurt people impacted by these decisions. The outcome of this project expects to be a series of techniques covering data understanding and enhancement, model development and fitting, and novelty detection, to reduce the damage of less-trustable data. The research expects to benefit the people and companies impacted by data-aided decision making in cybersecurity, healthcare and financial fraud detection, providing risk-control services.Read moreRead less
