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
Carbon dioxide conversion over nanostructured mixed metal catalysts. Nanocatalysts are particles of very small size that have the ability to accelerate chemical reactions. This project will develop nanocatalysts to convert carbon dioxide into other small molecules to provide new options for managing greenhouse gas emissions.
Characterization of Sub- and Super-Critical Fluids in Nanomaterials. In recent years, nano-porous materials have become the most potential media for applications in the areas of separation and purification, with materials such as carbon alloy, activated carbon fibre, carbon nanotube and their derivatives. Their effective utilisation depends on how well we characterise them for their adsorption capacities. In this project, we propose a new model for this characterisation and this model can be u ....Characterization of Sub- and Super-Critical Fluids in Nanomaterials. In recent years, nano-porous materials have become the most potential media for applications in the areas of separation and purification, with materials such as carbon alloy, activated carbon fibre, carbon nanotube and their derivatives. Their effective utilisation depends on how well we characterise them for their adsorption capacities. In this project, we propose a new model for this characterisation and this model can be used for the prediction of adsorption of multicomponent systems, which are common in separation and purification industries, without recourse to extensive experimentation. The success of this model could translate to cost savings in those industries.Read moreRead less

Reactive Intermediates in Atmospheric and Combustion Chemistry. Reactive intermediates are the key species that determine outcomes of the chemical reaction networks in atmospheric and combustion chemistry. However, most reactive intermediates remain undiscovered. The project aims to discover these intermediates using laser spectroscopy. Current models of atmospheric chemistry cannot account for the carbon balance over forests, nor the formation of secondary organic aerosols. Combustion models st ....Reactive Intermediates in Atmospheric and Combustion Chemistry. Reactive intermediates are the key species that determine outcomes of the chemical reaction networks in atmospheric and combustion chemistry. However, most reactive intermediates remain undiscovered. The project aims to discover these intermediates using laser spectroscopy. Current models of atmospheric chemistry cannot account for the carbon balance over forests, nor the formation of secondary organic aerosols. Combustion models struggle to predict how next-generation fuels burn in modern engines. The successful discovery of these intermediates would allow models to be more accurate and predictive. This will allow scientists, engineers and policy makers to make more informed decisions about atmospheric processes and design more efficient new fuels.Read moreRead less
