The project aims to engineer positively charged metal complexes and use them to explore the chemistry of bound activated alkane ligands. The transformation of cheap, plentiful alkanes into more valuable products is a major quest in chemistry, and complexes of alkanes bound to metals are expected to play a key role in transformations of alkanes. The project intends to use the activated metal bound alkane to transform the normally inert alkane into compounds with desirable functional groups. This should make the synthesis of alkane complexes stable at room temperature in solution a realistic possibility. These cheap, plentiful alkanes can be turned into more valuable products, bringing benefits to industry.Read moreRead less
Alkane transformations through binding to metals. Alkanes are fully saturated hydrocarbons and they are the major components of petroleum, including natural gas and liquid hydrocarbon fuels. They are abundant but finite, and their primary usage has been as fuels since they burn readily and release energy. Alkanes are relatively low-value, high-volume chemical feedstocks which are not easy to convert into more useful value-added materials. This project focuses on developing positively charged met ....Alkane transformations through binding to metals. Alkanes are fully saturated hydrocarbons and they are the major components of petroleum, including natural gas and liquid hydrocarbon fuels. They are abundant but finite, and their primary usage has been as fuels since they burn readily and release energy. Alkanes are relatively low-value, high-volume chemical feedstocks which are not easy to convert into more useful value-added materials. This project focuses on developing positively charged metal-based compounds that can bind directly to alkanes to increase their reactivity and enable their transformation into higher value products such as alcohols and olefins which are important chemical feedstocks.Read moreRead less
Plasmonic nanoparticle catalysis for nitrogen-based synthesis. Light can generate an optical force to capture small objects. This requires intense light – a laser, which limits optical trapping in catalysis applications. This project aims to apply plasmonic nanoparticles with normal-intensity light to take advantage of plasmonic-generated optical forces for catalytic chemical synthesis. The optical trapping/releasing of small molecules is highly selective and responsive to molecule structure and ....Plasmonic nanoparticle catalysis for nitrogen-based synthesis. Light can generate an optical force to capture small objects. This requires intense light – a laser, which limits optical trapping in catalysis applications. This project aims to apply plasmonic nanoparticles with normal-intensity light to take advantage of plasmonic-generated optical forces for catalytic chemical synthesis. The optical trapping/releasing of small molecules is highly selective and responsive to molecule structure and so presents a great opportunity to radically alter chemical synthesis pathways, which will be illustrated with reactions on liquid-solid and gas-solid interfaces. This highly innovative strategy will be used to discover new nitrogen-based syntheses which are both fundamentally and industrially important.Read moreRead less

This project aims to develop new iron catalysts as alternatives to the expensive and increasingly rare noble metals currently used in C-C bond forming reactions, the most important single-step in the fine-chemicals sector.
This project expects to create a flexible yet robust framework by introducing a hemilabile ligand into the backbone of the iron complex to control the number of vacant coordination sites.
Expected outcomes of this project are 1) iron complexes able to catalyse biaryl couplings from sustainable substrates and 2) knowledge on structure-property relationships of iron-based catalytic processes.
Australia will benefit by applying its own resources and help preserving the valuable noble metals for processes relying on them.Read moreRead less
Solar-Driven C-H Functionalization Reactions. This project aims to investigate the functionalization reaction of unreactive C-H bonds using light as the source of energy. Light is a transformative change to synthesis as thermal activation is exchanged to solar activation. The latter gives access to excited state chemistry and enables reaction steps that are thermally inaccessible. It is a key strategy to leverage synthesis to the demands of the 21st century and to minimise its ecologic footprint ....Solar-Driven C-H Functionalization Reactions. This project aims to investigate the functionalization reaction of unreactive C-H bonds using light as the source of energy. Light is a transformative change to synthesis as thermal activation is exchanged to solar activation. The latter gives access to excited state chemistry and enables reaction steps that are thermally inaccessible. It is a key strategy to leverage synthesis to the demands of the 21st century and to minimise its ecologic footprint. At the same time this strategy provides a lever to profoundly impact and drive new concepts in synthesis. Significant benefits are expected, such as increase in fundamental knowledge on photochemical processes, but also the access to new materials for applications as drugs or OLEDs.Read moreRead less
Inference for Hawkes processes with challenging data. The Hawkes processes are statistical models for the analysis of high-impact event sequences, such as bushfires, earthquakes, infectious diseases, and cyber attacks. When the times and/or marks are missing for some events or when the data is otherwise incomplete, it is challenging to fit these models and perform diagnostic checks on the fitted models. This project aims to develop novel statistical methods to fit these models in the presence of ....Inference for Hawkes processes with challenging data.
