Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy ....Mechanistic Studies on Biologically Active Iron Chelators. The need for orally effective drugs as alternatives to invasive treatment regimens such as subcutaneous infusion is an ongoing concern in health care. This is particularly true in people suffering iron overload. In many cases this condition is present at birth and thus the administration of vital iron chelation therapy via the oral route is a much preferred option. We have unearthed a novel series of candidates for iron chelation therapy (the pyridine-2-carboxaldehyde isonicotinoyl hydrazone [PCIH] analogues) which show oral activity. These chelators undergo some interesting iron catalysed oxidation chemistry and it is vital that the mechanism of this reaction be elucidated to determine whether it will be of biological significance upon administration of these compounds as iron chelators.Read moreRead less
New Synthetic Routes to the Immobilisation of Mixed Valence Transition Metal Complexes on Conducting Metal Oxides. Highly coloured, electrochemically active transition metal dyes may find application electrochromic devices, where they may switch between contrasting coloured forms through a simple redox reaction. A prerequisite is that the dye be immobilised onto a solid conducting support whilst preserving the electrochemical and optical properties of the dye found in solution. This project tack ....New Synthetic Routes to the Immobilisation of Mixed Valence Transition Metal Complexes on Conducting Metal Oxides. Highly coloured, electrochemically active transition metal dyes may find application electrochromic devices, where they may switch between contrasting coloured forms through a simple redox reaction. A prerequisite is that the dye be immobilised onto a solid conducting support whilst preserving the electrochemical and optical properties of the dye found in solution. This project tackles this problem through a combination of organic and inorganic synthesis to develop new electrochromic dyes that may be attached to mesoporous titania.Read moreRead less
Nanostructures of Titanium Dioxide and Titanates by Wet-chemistry. One-dimensional (1D) nanoparticulates of titanium dioxide (TiO2) and titanate synthesized by wet-chemistry approaches are new advanced materials of unusual properties. This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques. With such knowledge, we can effectively control the morphology on a scale of nanometers, and tailor the energy gap of these materials.

One-dimensional (1D) nanoparticulates of titanium dioxide (TiO2) and titanate synthesized by wet-chemistry approaches are new advanced materials of unusual properties. This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques. With such knowledge, we can effectively control the morphology on a scale of nanometers, and tailor the energy gap of these materials. This will significantly influence the photosemiconductive photocatalytic and lithium ions insertion behaviours of the particles so that advanced materials for solar energy conversion, photocatalysts for decomposing organic pollutants in environment, eletrode materials of lithium batteries can be developed.Read moreRead less
Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information ....Bimolecular chemistry at very low temperatures. Many chemical reactions involve short-lived and highly reactive intermediates that cannot be observed under ordinary reaction conditions. Hence, much of this chemistry is shrouded in mystery. This project aims to develop the ability to observe and monitor such reactions directly using a combination of spectroscopies at very low temperatures, where the molecules are more stable and reactions slower. These studies will give quantitative information on the nature of the reactive intermediates themselves, the nature of the products formed, and the reaction dynamics, and they are of fundamental importance for an understanding of chemical reactivity generally. The methodology developed will be applicable to the investigation of a wide range of processes.Read moreRead less
Investigation of novel sialic acid mimetics to target the spread of cancer. The mortality rates for many cancers afflicting the world's population are extremely high and these rates are consistent with the Australian experience. It is generally accepted that colon cancer, and cancers as a whole, are a significant healthcare issue and have immense socioeconomic impact. Alternative treatments preventing the spread of cancers would be of very significant benefit. This fellowship will provide the ....Investigation of novel sialic acid mimetics to target the spread of cancer.

It is generally accepted that colon cancer, and cancers as a whole, are a significant healthcare issue and have immense socioeconomic impact. Alternative treatments preventing the spread of cancers would be of very significant benefit. This fellowship will provide the opportunity for the discovery and development of such treatments that are based on the processes that utilise carbohydrates to facilitate the spread of tumours.Read moreRead less
