New solution methods will be provided, and new results about how these fluid flows evolve will be obtained. These are important problems with significance in modelling underwater explosions. They are also important in astrophysics, and will help explain the shapes of outflows from some stars or galaxies. The outcomes of the project will be a deeper mathematical understanding of which outflow shapes are stable, and under what circumstances they might become unstable. This will provide valuable information about galaxy shapes, and a new suite of computational methods for solving such problems.Read moreRead less

Nucleophilic carbenes as organocatalysts for asymmetric synthesis. Chemical compounds which come in two chiral mirror images (enantiomers) can have very different biological function. Often one form can have beneficial effects while the other can cause great harm (such as birth defects in the case of thalidomide). It is therefore very important for the drug industry to have asymmetric chemical reactions that lead specifically to only one enantiomer. The asymmetric reactions in this project ha ....Nucleophilic carbenes as organocatalysts for asymmetric synthesis. Chemical compounds which come in two chiral mirror images (enantiomers) can have very different biological function. Often one form can have beneficial effects while the other can cause great harm (such as birth defects in the case of thalidomide). It is therefore very important for the drug industry to have asymmetric chemical reactions that lead specifically to only one enantiomer. The asymmetric reactions in this project have been used previously to synthesise the anti-cancer metabolite roseophilin. The results of this project will ensure that there are many more similar success stories in the pharmaceutical and biotechnology industries.Read moreRead less
Metal complexes for activation and scission of small, multiply-bonded molecules. The outcome of this work is a series of metal complexes capable of cleaving the strong bonds in a number of small molecules of chemical importance. This will have a significant impact on industry by providing cheaper and safer alternatives to currently expensive and hazardous processes for producing nitrogen and phosphorus containing compounds.

Original metal-based catalysts for enzyme-inspired CO2 activation. The chemical utilisation of CO2 is one of two major strategies in achieving net negative CO2 emissions mitigating the environmental and socioeconomic damage of global warming. Inspired by the ability of natural enzymes to efficiently utilise molecules like CO2, this project aims to develop original metal-based catalysts as enzyme mimics for the efficient transformation of CO2.

The chemical utilisation of CO2 is one of two major strategies in achieving net negative CO2 emissions mitigating the environmental and socioeconomic damage of global warming. Inspired by the ability of natural enzymes to efficiently utilise molecules like CO2, this project aims to develop original metal-based catalysts as enzyme mimics for the efficient transformation of CO2. It will deliver practical strategies to transform CO2 into value-added materials permanently removing it from the atmosphere. Project outcomes are expected to enhance industry’s capacity to use CO2 as a feedstock chemical for the production of fuels and materials, providing significant economic and environmental benefits through CO2 upcycling and recycling.Read moreRead less
The development of homogeneous catalytic processes for the manufacture of new chemical products derivable from Australia's resources. The research proposed is deliberately aimed at exploiting opportunities that will arise as a result of changes that are taking place in the global petrochemical industry.

Metal complexes for sustainable light-driven synthesis. The aim of this project is to use cheap, abundant transition metal ions and visible light to enable challenging synthetic chemical reactions. The significant problems addressed are that most synthetic reactions using visible light currently require expensive precious metals, and fundamental reaction pathways used by Nature remain inaccessible. Both of these problems limit the scope of synthetic applications. The outcomes will be new knowled ....Metal complexes for sustainable light-driven synthesis.

The significant problems addressed are that most synthetic reactions using visible light currently require expensive precious metals, and fundamental reaction pathways used by Nature remain inaccessible. Both of these problems limit the scope of synthetic applications. The outcomes will be new knowledge and sustainable technologies that can better harness visible light for useful synthetic chemistry applications. The benefits will be more efficient and cost-effective routes to valuable molecules ubiquitous in everyday life.Read moreRead less

Halogen Bonding for Assembly and Separation in Solution. The properties of substances we experience in our daily lives owe much to very weak interactions taking place between molecules. Consider a cup of coffee: very weak interactions hold the water together as a liquid, and result in the biological action of caffeine within the body. The project aims to develop new materials based on an underexplored class of weak interactions known as halogen bonds. These interactions will be used to assemble ....Halogen Bonding for Assembly and Separation in Solution. The properties of substances we experience in our daily lives owe much to very weak interactions taking place between molecules. Consider a cup of coffee: very weak interactions hold the water together as a liquid, and result in the biological action of caffeine within the body. The project aims to develop new materials based on an underexplored class of weak interactions known as halogen bonds. These interactions will be used to assemble large molecules in solution, probe the presence of pollutants in water, and to separate active and inactive forms of pharmaceuticals. The development of health and environmental applications in the course of this project aim to significantly enhance our fundamental understanding of these weak interactions.Read moreRead less
New Look N-Heterocyclic Metallocenes of the Lanthanides Based on 4-Azapentalenyl Anions. Since there are abundant, but under utilised, reserves of lanthanide minerals in Australia, it is in Australia's best interest that their chemistry is developed into commercial applications in industrial catalysis. This project addresses this situation through the detailed study of carefully chosen organolanthanide compounds (specifically, comprising hetero-substituted metallocenes). The research strategy ....New Look N-Heterocyclic Metallocenes of the Lanthanides Based on 4-Azapentalenyl Anions.

This project addresses this situation through the detailed study of carefully chosen organolanthanide compounds (specifically, comprising hetero-substituted metallocenes). The research strategy will be directed towards advancing our knowledge in relation to fundamental chemical processes that are directly relevant to the industrial production of important commodity chemicals and polymers from often under utilised petroleum industry waste stocks.Read moreRead less
Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water.

Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge will provide a better understanding of the role of the physical and chemical properties of the fixatives in fixing the different compounds in wood resins. Molecular modelling will be used to design new fixatives that will be selective to a mixture of wood resins.
