Boryl Pincers and Beyond: Taming Borometallic Chemistry. Industrial applications of coordination complexes in catalysis reduce energy input and environmental impact but almost exclusively involve classical donors such as nitrogen, oxygen, sulfur and phosphorus. Boron, whilst prevalent and environmentally benign, is under-utilised in such applications, in part due to the high reactivity of the metal boron bond.

Industrial applications of coordination complexes in catalysis reduce energy input and environmental impact but almost exclusively involve classical donors such as nitrogen, oxygen, sulfur and phosphorus. Boron, whilst prevalent and environmentally benign, is under-utilised in such applications, in part due to the high reactivity of the metal boron bond.
This research will seek to tame and then exploit the unique features of boron within pincer ligand frameworks in metal coordination complexes, with particular attention focusing on, but not limited to catalytic alkyne metathesis.Read moreRead less
Bimetallic carbidos: hard-wiring a single atom of carbon. This project aims to explore the design, synthesis, characterisation and applications of novel materials in which metals are bridged by a single carbon atom. Materials based on metals (M) separated by a single oxygen atom (O) underpin all manner of technologies from the pigments of antiquity to modern electronics. Electronic/magnetic communication across MOM bridges is thus extremely well understood. Materials with two metals bridged by o ....Bimetallic carbidos: hard-wiring a single atom of carbon. This project aims to explore the design, synthesis, characterisation and applications of novel materials in which metals are bridged by a single carbon atom. Materials based on metals (M) separated by a single oxygen atom (O) underpin all manner of technologies from the pigments of antiquity to modern electronics. Electronic/magnetic communication across MOM bridges is thus extremely well understood. Materials with two metals bridged by one carbon atom (MCM) are in contrast, rare and poorly understood. Developing synthetic routes to such materials will make it possible to map the diversity of chemical and electronic features against theoretical models in search of new materials with unique reactivities and properties for commercial exploitation.Read moreRead less

This project aims to develop a new generation of aerospace aluminium alloys containing scandium. Over 30 million tonnes of high performance aluminium alloys are produced annually. Early investigations showed many beneficial effects of scandium on alloy behaviour, but research was abandoned due to scandium’s high cost. Australia has the largest deposit of scandium in the world, and Australian sustainable extraction technology will markedly lower the price. This project believes that now is an ideal time to capitalise scandium’s beneficial effects and be at the forefront of this new alloy development strategy. Anticipated outcomes are the creation of a new market with economic and sustainable opportunities for the Australian mining sector.Read moreRead less

The phase transformation thermodynamics of post-transition metals, which form low-melting-point alloys, remain largely unknown. This project aims to explore low-energy metallurgy pathways enabled by liquid metals to discover such dynamics. The strategy is to harvest structured/crystalline materials by incorporating target metal species into liquid metal solvents and stimulating autonomous phase separation and pattern formation during phase transition. Contemporary instruments and technologies will be employed to achieve active control of these fundamental processes at different scales. The expected outcomes will reveal new insights in traditional metallurgy as well as extend metallurgical concepts to electronics, optics, and catalysis.Read moreRead less
