Supramolecular assembly in photovoltaic electrode design: Studies of ordered porphyrin/acceptor complexes on polythiophene electrodes. This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships.

This research outlines an improved way to develop dye-sensitised photovoltaic solar cells for the conversion of sunlight into electricity, by increasing the molecular order of the cell components using host, guest interrelationships. As such, it addresses a problem of international concern 'How to reduce greenhouse gas emissions and stop global warming?' since solar cells do not produce carbon dioxide. To achieve our goals we draw on the skills of a team of experts from Australia (synthetic organic chemists), New Zealand (polymer and surface chemists) and Italy (photochemist and photophysicist). Such research is very appropriate for regional Australia, especially Central Queensland.Read moreRead less
Environmentally sustainable asymmetric synthesis: design and development of chiral hydrogen bonding organocatalysts. There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes.

There is a pressing need for more environmentally sustainable and economically viable methods for asymmetric synthesis. This project aims to design, synthesise and evaluate new organocatalysts based on the principle of hydrogen bonding activation, a common feature of Nature's catalysts, enzymes. These inexpensive, non-toxic, air- and moisture-stable catalysts may prove to be more efficient, selective and have broader applicability than catalysts based on transition metals. The growing Australian pharmaceutical and biotechnology industries will benefit from the development of these new Advanced Materials and the training provided to young scientists in the sought-after fields of asymmetric synthesis and catalysis.Read moreRead less
Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the pre ....Modelling of Adsorption Dynamics in Microporous Adsorbents Using Fractional Order Diffusion Equations. This project investigates the use of fractional order diffusion equations in modelling adsorption dynamics in microporous carbons. The long tail behaviour of adsorption processes cannot be readily explained by the classical second order Fickian model, and makes adsorption a candidate for the use of fractional order diffusion equations that have the potential to model such features. In the present project we shall develop suitable numerical techniques for solving the fractional order diffusion model, and apply these to the interpretation of experimental kinetic data. The outcome will be an improved model of adsorption dynamics considering the fractal nature of the solid.Read moreRead less
Development of an Adjustable Porphyrin-based Molecular Platform for Nanotechnology Applications. Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level.

Nanotechnology, the art of molecular control, is often heralded as the next industrial revolution. For this to be realised, the construction of useful devices will require precise control at the molecular level. Our control is realised through a process called self-assembly which means that the once the components of the device are correctly designed, the device will simply be able to put itself together. This research will use nature's light harvesting elements, namely porphyrins, and our ability to precisely control their position with respect to each other to build new, more efficient solar cells.Read moreRead less

This project seeks to incorporate non-equilibrium molecular dynamics calculations into particle scale models for adsorption kinetics. Molecular dynamics calculations will be performed for hydrocarbon molecules in small pores to obtain transport coefficients in pores of various sizes, at various bulk gas pressures and temperatures. These transport coefficients will be used in particle scale models to obtain a dynamic model, which will be utilised to interpret experimental data from the literature as well as that being obtained in our laboratory. Such first principles-based modelling has not been performed before at the particle scale, and will mitigate the empiricism in existing approaches.Read moreRead less
Molecular probes for pancreatic cancer. Cancer has overtaken heart disease as the main cause of premature death in Australia. Currently one in two men and one in three women are diagnosed with cancer during their lifetime. Pancreatic cancer is the fourth leading cause of cancer death in Australia, and the current lack of effective therapies results in a 1 year survival of just over 10%, and a 5 year survival of less than 5%. This project aims to identify and produce new compounds with novel mech ....Molecular probes for pancreatic cancer. Cancer has overtaken heart disease as the main cause of premature death in Australia. Currently one in two men and one in three women are diagnosed with cancer during their lifetime. Pancreatic cancer is the fourth leading cause of cancer death in Australia, and the current lack of effective therapies results in a 1 year survival of just over 10%, and a 5 year survival of less than 5%. This project aims to identify and produce new compounds with novel mechanisms of action that will facilitate our understanding of pancreatic carcinogenesis and provide the basis for the development of new therapeutic strategies. Australians diagnosed with pancreatic cancer in the future may directly benefit from the results of this work.Read moreRead less
Controlled Crystallisation of Bioactives. The new technologies developed in this project for bioactive recovery and particle design will allow the development of new value added products for Australia's growing biotechnology industry, especially in pharmaceuticals, neutraceuticals and functional foods.

This project will develop new strategies for economically viable recovery of bioactives from complex solutions, slurries and sludges of biomaterials eg. waste streams from milk and soy bean processing, and fermentation broths. These bioactives, often proteins, have growing applications as high value drugs, nutriceuticals and food additives but are difficult to separate and to maintain in an active form. Crystallisation will be used as a primary separation technique. Molecular studies of protein interactions will be used to predict good crystallisation conditions and linked to process crystallisation studies. Both standard and novel particle design strategies will be used to control crystal size and morphology, as well as package the boactive in a deliverable form without loss of activity.Read moreRead less
