Synthesis and characterisation of cadmium-free quantum dots. Quantum dots (QDs) - a highly functional class of nanocrystals - have a tremendous potential for applications in life sciences, energy conversion and electronics; however, their toxicity represents a problem for almost any utilisation. This project aims to find new synthesis methods for less toxic QDs and will thus pave the way for the use of these particles.
Designing reactivity of homogeneous and heterogeneous water-splitting catalysts using muti-dimensional site-selective spectroscopies. New classes of heterogeneous manganese-calcium water splitting catalysts analogous to the unique biological water splitting cofactor have recently emerged but with far lower catalytic rates than seen for the biological system. These new materials are promising targets for large-scale hydrogen fuel production with low cost, high efficiency and ease of manufacture. ....Designing reactivity of homogeneous and heterogeneous water-splitting catalysts using muti-dimensional site-selective spectroscopies. New classes of heterogeneous manganese-calcium water splitting catalysts analogous to the unique biological water splitting cofactor have recently emerged but with far lower catalytic rates than seen for the biological system. These new materials are promising targets for large-scale hydrogen fuel production with low cost, high efficiency and ease of manufacture. To achieve this, the performance gap between these materials and the homogenous biological catalyst must be bridged. Multi-dimensional site-selective spectroscopies, including magneto/optical resonance methods which are aimed to be developed in this project are expected to provide new, atomic level understanding of properties needed to achieve high catalytic efficiency, thus guiding rational catalyst design.Read moreRead less

Summary
A New Breed of Metallosupramolecular Assembly. Self-assembly is the ready formation of complex structures from simple components. Nature uses this to generate its most impressive molecular machinery to carry out complex tasks. Metallosupramolecular chemists combine simple components (metal ions and organic ligands) to create synthetic variants to fulfil similar roles.

Self-assembly is the ready formation of complex structures from simple components. Nature uses this to generate its most impressive molecular machinery to carry out complex tasks. Metallosupramolecular chemists combine simple components (metal ions and organic ligands) to create synthetic variants to fulfil similar roles. Current methods have limitations, and this project aims to create a new structural type: large and controllably variable metallo-foldamers (structures consisting of metal ions and ligands that coil like DNA). As well as benefiting fundamental knowledge, these molecules will be functional. They are expected to improve performance with enhanced outcomes in photophysical, photochemical, catalytic, and sensing applications.Read moreRead less

This project aims to make luminescent solar concentrators that can harness solar energy from surfaces not suited for conventional solar cells, such as car windows. It will design, synthesise and conduct detailed energy transfer studies of robust inorganic quantum dot arrays with fit-for-purpose precise spectral properties. Synthetic light-harvesting dye arrays have often been proposed to solve bottleneck challenges in the solar energy sector but there are issues with stability, processing and their photophysical output matching market needs. This project’s dyes are expected to create market opportunities for Australian luminescent solar concentrator technology.Read moreRead less
Tuning the electrolytes for high efficiency solar splitting of water. This project will develop a new technology that uses ionic liquids and sunlight to split water into hydrogen and oxygen to be used as a clean fuel. Australia has abundant sunlight, is very close to the growing energy markets of the Asia-Pacific region, and is ideally placed to benefit from this new technology.
Selective photocatalytic lignin biomass conversion. If the prospective ‘hydrogen economy’ is to use hydrogen as a fuel and energy carrier to replace fossil sources, vast amounts of renewable cheap hydrogen must be available. A likely candidate is catalytic water splitting by sunlight. The hydrogen can be made affordable, by coupling hydrogen production to a higher value-added stream. The aim of this project is to produce a stable, hybrid heterogenous catalyst system able to oxidise organic subst ....Selective photocatalytic lignin biomass conversion. If the prospective ‘hydrogen economy’ is to use hydrogen as a fuel and energy carrier to replace fossil sources, vast amounts of renewable cheap hydrogen must be available. A likely candidate is catalytic water splitting by sunlight. The hydrogen can be made affordable, by coupling hydrogen production to a higher value-added stream. The aim of this project is to produce a stable, hybrid heterogenous catalyst system able to oxidise organic substrates derived from lignin biomass as an adjunct to visible light hydrogen generation from water. The significance will be to provide fuels and organic chemicals for industry from biomass, water and sunlight and catalytically remediate waste water with sunlight.Read moreRead less

This project aims to apply new computational methods developed by the applicant to characterise the interactions between colloidal nanorods and their self-assembly in the presence of interfaces and directional interactions. While nanoparticles can currently be made in a staggering array of shapes, patterns and materials, organising such objects into extended structures that could revolutionise technology remains a challenge. The expected outcome is a robust strategy for making monolayer films of rods aligned perpendicular to a variety of interfaces for the fabrication of solar cells, microfiltration membranes and biosensors.Read moreRead less
