Gas phase studies of reactive organic radicals: a novel approach using mass spectrometry. Radical reactions play a crucial role in a range of important chemistries, ranging from the formation of photochemical smog to the accumulation of pathogens in the ageing body. Despite their importance, the reactions of many radicals are poorly understood because of current experimental limitations. In this project we propose to develop two new and broadly applicable techniques for probing radical chemistry ....Gas phase studies of reactive organic radicals: a novel approach using mass spectrometry. Radical reactions play a crucial role in a range of important chemistries, ranging from the formation of photochemical smog to the accumulation of pathogens in the ageing body. Despite their importance, the reactions of many radicals are poorly understood because of current experimental limitations. In this project we propose to develop two new and broadly applicable techniques for probing radical chemistry in the gas phase via novel applications of mass spectrometry. Combined with quantum chemical calculations and state-of-the-art thermodynamic measurements these methods will provide a comprehensive understanding of the reactivity of key organic radicals.Read moreRead less

This proposal aims to carry out state-of-the-art chemistry research using computer modelling rather than traditional laboratory methods. The computer calculations are directed towards designing catalysts that will provide more efficient ways to convert environmentally harmful carbon dioxide to a valuable chemical fuel methanol, and to convert toxic polychlorinated hydrocarbon wastes to benign products. The increased understanding of free radicals that will stem from this research may ultimately help in dealing with problems associated with heart disease, some forms of cancer and vitamin B12 deficiency. New generations of chemists will be trained at the highest level in this burgeoning field of computational chemistry.Read moreRead less

In particular, new catalysts (i.e. agents that increase the speed and selectivity of chemical reactions) will be generated and the first steps towards process innovation will be taken, using high-throughput equipment unique in the Southern Hemisphere. These new catalysts will be the basis for the design of new and/or improved industrial processes that will be ?greener?, safer, use fewer resources, produce less waste and are generally more efficient and effective. As a result the Australian chemicals industry will be more competitive.Read moreRead less
Molecular Recognition in Chiral Ionic Liquids as Basis for the Design and Synthesis of New Enantioselective Heterogeneous Catalysts and Membranes. Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.

Molecules that can exist as mirror images, each with different, e.g., beneficial vs. toxic properties, underpin the pharmaceutical industry and increasingly new highly selective pesticides, and flavours/fragrances.
Current commercial pathways often make mixtures of the mirror images that then need to be separated laboriously. These routes are inefficient, creating waste and use resources poorly.
We aim to create solutions for these problems, using supported thin films of special, new types of salts that are liquid at room temperature, and which have other unusual chemical properties that make them ideally suited to enable efficient conversions.Read moreRead less

Membrane interactions and neurotoxicity of Amyloid Abeta peptides from Alzheimer's disease. A consequence of the increase in human life span is that age-related neurodegenerative diseases such as Alzheimer's disease (AD) are more prevalent. Currently there are limited therapeutic treatments and no cure for AD. The key protein causing AD is Abeta and characterization of the toxic species of this peptide is critical towards identifying potential therapeutic targets.

A consequence of the increase in human life span is that age-related neurodegenerative diseases such as Alzheimer's disease (AD) are more prevalent. Currently there are limited therapeutic treatments and no cure for AD. The key protein causing AD is Abeta and characterization of the toxic species of this peptide is critical towards identifying potential therapeutic targets. This proposal aims to study mutant peptides made synthetically and to identify a membrane-binding site. By establishing which lipid is critically involved in membrane binding of Abeta and mediating subsequent cell death, drugs may be developed to prevent the binding of Abeta to membranes resulting in neuronal survival and prevention of memory loss in AD patients.Read moreRead less
