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. These inexpensive, non-toxic, air- and moisture-stable catalysts may prove to be more ....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. 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
Solution Processable, High Dimensional Dendrimers for Plastic Electronics. Microelectronics are present in our everyday life, from numerous chips in our vehicles to our mobile telephones; and the list is almost infinite. The electronics used today are limited to rigid surfaces, and are incompatible for the next generation of technology such as rollable displays and radio frequency identification cards. This proposal describes the development of a new class of high performance flexible electronic ....Solution Processable, High Dimensional Dendrimers for Plastic Electronics. Microelectronics are present in our everyday life, from numerous chips in our vehicles to our mobile telephones; and the list is almost infinite. The electronics used today are limited to rigid surfaces, and are incompatible for the next generation of technology such as rollable displays and radio frequency identification cards. This proposal describes the development of a new class of high performance flexible electronic inks that could be used in the next generation of microelectronics. There is a huge commercial interest in these electronic ink materials and this market is projected to be $7.7 billion by 2012. The proposed electronic inks address issues with current materials such as processability, performance and reproducibility.Read moreRead less
Nitroxide-containing scaffolds for controlling biofilm-related infections. Bacterial biofilms are a major problem in healthcare systems around the world as they cause persistent and chronic infections, including those associated with medical implants and cystic fibrosis. This project aims to develop new chemical approaches to deliver nitroxides at surface interfaces and in microparticles to facilitate long term control over biofilm growth. It is expected that these functionalised scaffolds will ....Nitroxide-containing scaffolds for controlling biofilm-related infections. Bacterial biofilms are a major problem in healthcare systems around the world as they cause persistent and chronic infections, including those associated with medical implants and cystic fibrosis. This project aims to develop new chemical approaches to deliver nitroxides at surface interfaces and in microparticles to facilitate long term control over biofilm growth. It is expected that these functionalised scaffolds will represent a breakthrough in the field and will have a profound impact by reducing infection rates associated with medical devices and improving airway clearance in cystic fibrosis patients.Read moreRead less
Linking chemical synthesis with protein discovery to reveal key biological pathways. The project aims to pioneer a chemical biology technology to deliver a much better understanding of key molecules that regulate diseases such as cancer. For decades phorbol esters have been prominent molecules for controlling cell switches in complex diseases but our knowledge is incomplete because of the limited natural abundance of these molecules.
Neurotrophic Active Natural Products: Total Synthesis and Biological Evaluation of Neovibsanins A and B, and Analogues. New chemical entities (drug candidates) that promote neurite outgrowth have significant ramifications to mankind as they have real potential to repair damaged, or grow replacement, nerve cells affected by neuro and central nervous system (CNS) degenerative disease (e.g. Alzhiemer's, Parkinson's, Huntington's etc).

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

Despite significant research being directed toward cancer treatment, 7.6 million people died world wide in 2007. Early detection and treatment is widely recognised as being effective in significantly reducing mortality rates. Biomedical imaging techniques are routinely used for detection and staging of many cancers. However, greater sensitivity is required so that these techniques can be applied to very early detection of tumours. To overcome this short-coming the next generation of imaging probes will be developed, which will require fundamental investigations in polymer and nanomaterials science to maximise imaging sensitivity and extend probe functionality. Successful outcomes will lead to significant benefits to healthcare in Australia.Read moreRead less

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
