Resolving dissolved organic matter: new multi-dimensional separation approaches. To fully understand and model global carbon cycles the source, nature and fate of oceanic dissolved organic carbon is an essential element. This project will develop, model and apply new orthogonol and complementary separation science based technologies to further the comprehensive characterisation and understanding of these complex systems.
Hydrogen: an overlooked intermediate during anoxia in permeable sediments. This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better manageme ....Hydrogen: an overlooked intermediate during anoxia in permeable sediments. This project aims to quantify the respiratory pathways and the importance of hydrogen as an intermediate during anoxia in permeable (sand) sediments which dominate our coastline. It is anticipated the findings of this project will enable more accurate fundamental understanding of sediment diagenetic processes which control nutrient regeneration and loss pathways in the marine environment. This will enable better management of these environments in the face of increasing coastal population growth.Read moreRead less
Organometallic materials for photonics. New high performance materials are required for applications in photonics, an area of increasing importance for Australia's high technology industries.

New high performance materials are required for applications in photonics, an area of increasing importance for Australia's high technology industries. This project addresses two critically important requirements in photonics: materials with enhanced nonlinear optical merit (both quadratic and cubic), needed for applications in optical communications, data storage and computer systems, and materials with significant optical limiting properties, required for laboratory optical device protection and military applications. Concomitant with these studies, the fundamental organometallic chemistry of alkynylmetal complexes and clusters will be developed, leading into oligomeric, dendritic and polymeric species which are of intrinsic, as well as applied, interest.Read moreRead less

Transition metal clusters are closed polyhedral molecules that have been studied intensively for many years, initially for intrinsic interest, and subsequently as models of / precursors for catalysts effecting industrially important chemical transformations. More recently, clusters have been identified as promising optical limiters, required for many technological applications including optical device and eye protection from high power lasers. By focussing on the syntheses, electronic and optical properties of specific monomeric, oligomeric (including macrocyclic), dendritic and polymeric cluster-containing systems, we will develop fundamental cluster chemistry, prepare processable functional polymetallic materials, and probe the possible utility of cluster-based materials as optical limiters.Read moreRead less

Harnessing light and electricity to drive chemical synthesis. This project will explore and establish original strategies that use inputs of energy (light and electricity) to break or form chemical bonds, which can provide new or improved access to valuable compounds. In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes ....Harnessing light and electricity to drive chemical synthesis.

In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes of the project will include the development of new technology for organic synthesis and forging novel approaches for chemical alkylation and cross-coupling reactions. This can contribute to making important compounds more efficiently, safely and cheaper to produce in the future.Read moreRead less
