The photons take charge: Elucidating the structure and stability of distonic radical anions by mass spectrometry and photoelectron spectroscopy. Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project w ....The photons take charge: Elucidating the structure and stability of distonic radical anions by mass spectrometry and photoelectron spectroscopy. Recent work has discovered that certain radical anions have electronic configurations that defy chemical convention and exhibit exceptional radical stability. Exploitation of this breakthrough first requires experimental elucidation of the intrinsic electronic structure of these compounds and how it relates to their remarkable properties. This project will probe the fundamental structure and energetics of radical anions by modifying instrumentation to enable multi-step gas-phase ion synthesis to be efficiently coupled with anion photoelectron spectroscopy. These investigations are essential to revealing the scope of this phenomenon in free radical chemistry and biology and could inform future development of new catalysts for polymerisation.Read moreRead less

New insights into free radical reactivity via gas phase studies of radical anions. Free radicals are known to be critical reactive intermediates in chemical processes ranging from the formation of photochemical smog, through combustion to the onset of age-related diseases. This research increases our understanding of how free radicals react and will thus allow for more accurate prediction, and in some instances greater control, of the outcomes of chemical reactions and their health and environme ....New insights into free radical reactivity via gas phase studies of radical anions. Free radicals are known to be critical reactive intermediates in chemical processes ranging from the formation of photochemical smog, through combustion to the onset of age-related diseases. This research increases our understanding of how free radicals react and will thus allow for more accurate prediction, and in some instances greater control, of the outcomes of chemical reactions and their health and environmental consequences. New instrumental technologies will be developed and young Australian researchers will be trained here, and with collaborators in the USA, in state-of-the-art techniques (particularly in mass spectrometry) that are essential to our emerging technology-based economy.Read moreRead less
Coinage metal nanoclusters: synthesis, structure and reactivity. Metal catalysts play important roles in the multi-billion dollar production of many industrial and fine chemicals used in wide-ranging applications including pharmaceuticals, insecticides and polymers.

Metal catalysts play important roles in the multi-billion dollar production of many industrial and fine chemicals used in wide-ranging applications including pharmaceuticals, insecticides and polymers. Despite the importance of metal catalysed reactions, the molecular details of such processes remain poorly understood. Breakthrough studies highlight that reactions previously thought to be catalysed by discrete metal catalysts are in fact catalysed by metal nanoclusters. This project involves the application of advanced mass spectrometric and computational methods to explore the formation and reactivity of copper, silver and gold nanoclusters. Identification of key reactive intermediates will inform the design of next generation catalysts.Read moreRead less
A new approach to the generation of long-lived charge-separated states in rigid Donor-Bridge-Acceptor systems. Electron transfer and energy transfer are ubiquitous in nature and they provide the key to the design of energy transducing materials. Considerable effort is being expended into studying light-induced electron transfer which leads to the formation of a charge-separated state or molecular "battery". To be useful, these batteries should have lifetimes at least in the microsecond domain ....A new approach to the generation of long-lived charge-separated states in rigid Donor-Bridge-Acceptor systems. Electron transfer and energy transfer are ubiquitous in nature and they provide the key to the design of energy transducing materials. Considerable effort is being expended into studying light-induced electron transfer which leads to the formation of a charge-separated state or molecular "battery". To be useful, these batteries should have lifetimes at least in the microsecond domain and this is not easily achieved in practice. This project will explore a new, elegant, and promising approach to the efficient generation of very long-lived charge-separated states in rigid systems, which is based on triplet sensitisation.

This project aims to develop methods to create actively-driven self-assembled systems that do work on the environment in the way many natural functional assemblies operate. This project will combine the latest advances in supramolecular chemistry and non-equilibrium systems to discover how chemical energy drives the formation of transient self-assembled structures. An expected outcome from this project includes a new understanding of the relationship between the chemical fuel flows versus the spatial organisation of self-assembled systems, including living systems. The knowledge gained in this project will benefit the design of nanoscale self-assembled structures that can carry out work and complex mechanical tasks at much larger length scales.Read moreRead less
Exploitation of unusual patterns of reactivity of peptides towards radicals. Life depends on free radical reactions of peptides and proteins but, for these compounds to exist, these must be inherently resistant to radicals.

Life depends on free radical reactions of peptides and proteins but, for these compounds to exist, these must be inherently resistant to radicals. This project aims to combine state-of-the-art experiment and theoretical computations to build a detailed picture of peptide and protein radical reactivity, in order to explain this paradox and resolve ambiguities regarding processes through which radical damage to peptides occurs and is repaired. The project also aims to critically evaluate the basic concept of the fidelity of amino acid incorporation during protein biosynthesis. The results of this project could underpin the development of new strategies and therapeutics to treat human diseases, and new materials and synthetic methods to increase the utility of peptides in biotechnology.Read moreRead less

This project aims to synthesise new carbohydrate-based surfactants optimised for use as cryoprotectants, and to accurately measure, model and optimise their performance. The project will use state-of-the-art experimental methods and advanced phase-field modelling techniques to optimise the cryoprotectants so that they reduce osmotic stress in cells and inhibit ice crystal growth during freezing and thawing. The expected outcomes will be novel cryoprotectants that are easy to synthesise, non-toxic and effective, opening up new possibilities for the cryopreservation of cells, organs and possibly even whole organisms. This will have broad impact in critical applications such as long-term blood storage, reproductive technology and stem cell therapy, as well as preservation of endangered species.Read moreRead less
