Gas Phase Reactivity of Charged Peptide and DNA Radicals: Fundamentals and Applications. Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease). Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unch ....Gas Phase Reactivity of Charged Peptide and DNA Radicals: Fundamentals and Applications. Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease). Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unchartered area! We will examine the fundamental chemistry (unimolecular and bimolecular reactions) of these systems and build upon some exciting preliminary results which suggest potential applications (e.g. as a proteomics tool to sequence and distinguish between leucine and isoleucine residues in peptides).Read moreRead less

Controlled Supramolecular Assembly in Aqueous Molecular and Macroscopic Systems. This project uses benign and mainly bio-degradable materials to produce hydrogels which are remarkable new materials containing at least ninety-eight percent water which may be made into films. Similar films are proving to be valuable in covering wounds, particularly serious burns, and in greatly improving wound healing and tissue growth. They may also be useful in new coating and aircraft de-icing technologies. The ....Controlled Supramolecular Assembly in Aqueous Molecular and Macroscopic Systems. This project uses benign and mainly bio-degradable materials to produce hydrogels which are remarkable new materials containing at least ninety-eight percent water which may be made into films. Similar films are proving to be valuable in covering wounds, particularly serious burns, and in greatly improving wound healing and tissue growth. They may also be useful in new coating and aircraft de-icing technologies. These environmentally friendly materials are likely to find a multitude of uses as their development progresses. Young Australians involved in the project will gain experience in cutting edge science, its practical applications, and in international collaboration - a training essential to Australia's future prosperity.Read moreRead less

X-ray snapshots of chemical transformations in open framework materials. The aim of this project is to unearth structural insights into the chemistry of coordinatively unsaturated metal complexes – reactive species lacking their full complement of binding groups – by isolating them within a carefully designed metal-organic framework and examining them via single crystal X-ray diffraction. Such intrinsically reactive species play an important role in metal-based catalysis, but their definitive st ....X-ray snapshots of chemical transformations in open framework materials. The aim of this project is to unearth structural insights into the chemistry of coordinatively unsaturated metal complexes – reactive species lacking their full complement of binding groups – by isolating them within a carefully designed metal-organic framework and examining them via single crystal X-ray diffraction. Such intrinsically reactive species play an important role in metal-based catalysis, but their definitive structural characterisation remains a significant challenge. This project aims to facilitate a detailed understanding of how these species bind and activate substrates and thus provide important first steps towards developing novel adsorbents for separations and efficient catalysts.Read moreRead less

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.

All-carbon molecules in metal complexes - novel materials and intermediates. An important requirement for the future is new materials with unusual properties that can be controlled. The need for ever smaller electronic devices requires knowledge about appropriate properties (particularly electronic) of molecules designed to model devices such as wires, switches, etc. This work seeks to design, measure and evaluate such molecules, which are based on chains of carbon atoms linking metal centres ....All-carbon molecules in metal complexes - novel materials and intermediates. An important requirement for the future is new materials with unusual properties that can be controlled. The need for ever smaller electronic devices requires knowledge about appropriate properties (particularly electronic) of molecules designed to model devices such as wires, switches, etc. This work seeks to design, measure and evaluate such molecules, which are based on chains of carbon atoms linking metal centres which can gain or lose electrons readily. As the electronic structure changes, so do the physical (photo, solid-state) and chemical properties (reactivity). Improved understanding of these features will benefit development of advanced technology and new materials.Read moreRead less
