Polynuclear Metal Complexes as Molecular Nanomagnets. Computer hard drives and other devices use tiny particles of magnetic materials to store digital information. Technological advances require an increase in the density of information storage and therefore even smaller magnetic particles. This project has the potential to synthesise materials where a single molecule could act as the smallest possible unit of magnetic memory. The future application of these materials may provide an increase ....Polynuclear Metal Complexes as Molecular Nanomagnets. Computer hard drives and other devices use tiny particles of magnetic materials to store digital information. Technological advances require an increase in the density of information storage and therefore even smaller magnetic particles. This project has the potential to synthesise materials where a single molecule could act as the smallest possible unit of magnetic memory. The future application of these materials may provide an increase of three orders of magnitude in information storage density. In addition, they may find employment in quantum computers, which can perform calculations exponentially faster than conventional computers.Read moreRead less

Dietary selenium supplementation has great potential as a preventative treatment for a range of human health conditions, including cancer, that widely affect the Australian population. However, the adverse effects of such treatments are not fully recognised. This project will increase our knowledge of how selenium compounds are stored and utilised in the body and relate the information to clinical observations regarding dietary intake of selenium and other compounds. The new understanding generated will delineate the conditions for safe intake, so that the beneficial effects associated with selenium supplementation may be harnessed more effectively.Read moreRead less

New Chiral Metal Catalysts; Going Beyond the State of the Art. The synthesis of both natural and unnatural organic compounds in optically active form is a central challenge in chemistry. Because the most important molecules in nature are chiral and of specific handedness, there exists a growing need to access any given organic compound in its optically pure form. Asymmetric catalysis offers the most elegant way to solving this problem and this project will target some of the difficult challenges ....New Chiral Metal Catalysts; Going Beyond the State of the Art. The synthesis of both natural and unnatural organic compounds in optically active form is a central challenge in chemistry. Because the most important molecules in nature are chiral and of specific handedness, there exists a growing need to access any given organic compound in its optically pure form. Asymmetric catalysis offers the most elegant way to solving this problem and this project will target some of the difficult challenges in realising asymmetric synthesis, building new, privileged chiral ligands, opening new catalytic pathways for constructing chiral compounds and understanding the intimate catalytic pathway that enables reactivity and selectivity. This will generate applications across the chemical industries.Read moreRead less
Probing and Developing Hypoxia-Selective Anti-Cancer Agents. The development of compounds that are effective in the treatment of cancer and are less toxic than existing drugs depends on the selective targeting of tumours. Solid tumours have poorly oxygenated regions which represent unique chemical environments that can be targeted using selectively activated compounds. In this project we will develop the first in situ methods for monitoring the activation state in solid tumours to establish the ....Probing and Developing Hypoxia-Selective Anti-Cancer Agents. The development of compounds that are effective in the treatment of cancer and are less toxic than existing drugs depends on the selective targeting of tumours. Solid tumours have poorly oxygenated regions which represent unique chemical environments that can be targeted using selectively activated compounds. In this project we will develop the first in situ methods for monitoring the activation state in solid tumours to establish the selectivity of activation. These results will be used to tune the properties of two novel classes of selectively activated compounds and thereby develop agents able to treat the most problematic of cancers.Read moreRead less

Catalytic currency: the role of size-reactivity relationships of simple and mixed 'coinage' metal clusters in C-C bond forming reactions. Chemicals have a profound influence on our daily lives. For instance, the petrol we use in our cars, the plastics used for our shopping bags or the margarine we eat. A common theme of all these products is the use of catalysts in their industrial manufacture. Thus, this Australian Research Council funded project aims to shed light on the role of some catalysts ....Catalytic currency: the role of size-reactivity relationships of simple and mixed 'coinage' metal clusters in C-C bond forming reactions. Chemicals have a profound influence on our daily lives. For instance, the petrol we use in our cars, the plastics used for our shopping bags or the margarine we eat. A common theme of all these products is the use of catalysts in their industrial manufacture. Thus, this Australian Research Council funded project aims to shed light on the role of some catalysts in breaking and forming chemical bonds and attempts to set rules to develop new and improved ones. Improved catalysts will not only reduce the cost of goods manufacturing, but will also reduce waste products and energy consumption. This research will also train new scientists and contribute to the enhancement of Australia's research profile.Read moreRead less

Breakthrough microprobe and nanoprobe technologies, involving X-ray, visible and infrared light can focus into different components of mammalian cells in order to interrogate the biochemistry that is occurring therein. Each of the different wavelengths of light provides complementary biochemical information that enables a deeper understanding of changes in cells that occur as a function of drug treatments and disease processes. This will provide unprecedented information as to where drugs go and how they are transformed inside cells that, in turn, may revolutionalise the way in which new drugs are designed that have higher specificity and fewer side effects.Read moreRead less
