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

Summary
Time-resolved observation of highly transient events by a novel digital high-speed camera. Highly transient, that is, rapidly changing, events occur in nature and in almost every field of science and engineering. Knowledge and understanding of these processes is vital for the design of better and innovative machines, materials and instruments. Valuable insight into these processes can be gained if one can visualise them by means of high-speed photography. This application seeks the acquisition o ....Time-resolved observation of highly transient events by a novel digital high-speed camera. Highly transient, that is, rapidly changing, events occur in nature and in almost every field of science and engineering. Knowledge and understanding of these processes is vital for the design of better and innovative machines, materials and instruments. Valuable insight into these processes can be gained if one can visualise them by means of high-speed photography. This application seeks the acquisition of a novel and unique digital camera system that would allow one to observe rapidly occurring processes with unprecedented clarity. The availability of such a system would significantly strengthen cutting-edge research activities in various disciplines that would ultimately lead to the development of original and innovative products.Read moreRead less
Towards a steady-state fusion reactor: understanding and controlling eruptive instabilities in tokamaks. The lifetime of future fusion reactors may be severely compromised by periodic releases of internal energy which can damage the reactor walls. In an international research effort that is based on unique Australian optical technologies, the project aims to resolve some of the key issues that should allow these instabilities to be suppressed.
Electron, positron, and heavy-particle collisions with molecules. This project aims to develop a computational approach to collisions involving molecular targets with electrons, positrons and heavy particles. Recently, the approach to atomic collisions, the Convergent Close Coupling (CCC) method, has been extended and verified for positron, electron, and heavy particle collisions with the simplest molecular systems (molecular hydrogen and its ion). This project now aims to extend the CCC method ....Electron, positron, and heavy-particle collisions with molecules.

Recently, the approach to atomic collisions, the Convergent Close Coupling (CCC) method, has been extended and verified for positron, electron, and heavy particle collisions with the simplest molecular systems (molecular hydrogen and its ion). This project now aims to extend the CCC method to study collisions with more complex molecules. Expected benefits include more accurate data for diagnostic tools such as Positron Emission Tomography, and potential advances in particle-based cancer therapy.Read moreRead less

Understanding molecular negative ion production for use in pathology. The project aims to increase the yield of molecular negative ion sources by improving our understanding of the formation of ion beams from plasma sources and expand our knowledge of molecular negative ion generation in plasma environments leading to brighter ion beams. For example, understanding cancer requires cellular level tools to map how cells are changing. These maps are made using ion beams which are scanned across cell ....Understanding molecular negative ion production for use in pathology. The project aims to increase the yield of molecular negative ion sources by improving our understanding of the formation of ion beams from plasma sources and expand our knowledge of molecular negative ion generation in plasma environments leading to brighter ion beams. For example, understanding cancer requires cellular level tools to map how cells are changing. These maps are made using ion beams which are scanned across cells to remove material that is analysed at the atomic and molecular level. Ion beams are produced from plasma sources, but much of their operation is not understood. Such improved ion beams are expected to enable inexpensive and fast cellular level pathology at even small hospitals to tackle cancer for society’s benefit.Read moreRead less
Low-energy electron transport in soft-condensed biological matter. To obtain optimal accuracy and selectivity of ionising radiation based technologies requires an understanding and quantification of the underpinning fundamental physical processes. This project will focus on developing accurate theoretical models of low-energy electron transport in biological matter which account for new physical mechanisms.
