Summary
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
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.
Metal-promoted bond functionalisation: new routes to amides and thioamides. This project aims to discover new metal-promoted methods to synthesise amides and thioamides, important structural motifs in chemistry and biology. The project will use a mechanism-based approach that integrates theory with gas- and solution-phase experiments to discover new chemical reactions. A benefit of this research will be new eco-friendly alternatives to existing processes, thereby reducing waste and eliminating t ....Metal-promoted bond functionalisation: new routes to amides and thioamides.

Summary
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. It will deliver practical strategies to transform CO2 ....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. 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
What controls trace element levels in ore sulfides? A laser-ICPMS perspective. Sub-surface hydrothermal gold and base metal orebodies are surrounded by aprons of elevated metal concentrations, mainly within micro-sulfides, which is one sign mineral explorers use to widen their target. Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better model ....What controls trace element levels in ore sulfides? A laser-ICPMS perspective. Sub-surface hydrothermal gold and base metal orebodies are surrounded by aprons of elevated metal concentrations, mainly within micro-sulfides, which is one sign mineral explorers use to widen their target. Here we test whether the hostrock contributes metal in the most distant parts of such halos, and if so, what factors control where hostrock metal begins to be detectable in a given system. We will make better models of how metalliferous waters react with rock, potentially translating into million dollar savings through more efficient exploration. The ultrafine sampling and precision analyses required for this are possible because of an ARC-funded core program at CODES.Read moreRead less
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
3D printed microchemical devices and systems. This project aims to address the barriers faced by 3D printing in chemistry. 3D printing can create bespoke 3D structures within a fraction of time and cost compared to traditional fabrication. However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components. Hence, this project will develop novel gold coating techniques and explore high-resolution 3D printing to overcome th ....3D printed microchemical devices and systems. This project aims to address the barriers faced by 3D printing in chemistry. 3D printing can create bespoke 3D structures within a fraction of time and cost compared to traditional fabrication. However, its scope in chemistry has been limited by the poor chemical robustness, biotoxicity and low resolution of the 3D printed components. Hence, this project will develop novel gold coating techniques and explore high-resolution 3D printing to overcome these challenges. The project should generate commercially significant products (analytical platforms), technology (gold coating) and patents. The developed systems and technologies will address Australian research challenges in advanced manufacturing and enable on-site environmental monitoring.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
