New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of ....New Strategies for Modelling Polyoxometalates. Polyoxometalates are a versatile class of genuine nanomaterials with remarkable chemical and physical properties and dimensions ranging from tens to tens of thousands of atoms. Designing functional materials which exploit their enormous potential is limited by practical difficulties in their structural characterization and restrictions on our ability to model their behaviour. In this project, we will develop a new strategy for computer modelling of polyoxometalates based on the classical molecular mechanics approach and high-level techniques. This novel line of attack will be exploited in the characterization of large and highly substituted derivatives which are key to developing functional materials.Read moreRead less

Patterned assemblies of molecules on surfaces. Because of their redox and photophysical properties, artificial porphyrin systems have been designed for applications such as light-harvesting antennae, catalysts and sensors. Control of molecular orientation is required in order to construct practical devices, and in this project methods of assembling porphyrins on surfaces in well-defined patterns will be developed.

Because of their redox and photophysical properties, artificial porphyrin systems have been designed for applications such as light-harvesting antennae, catalysts and sensors. Control of molecular orientation is required in order to construct practical devices, and in this project methods of assembling porphyrins on surfaces in well-defined patterns will be developed. Sophisticated methods will be used to characterise the films produced in these ways, in order to provide the information necessary to refine procedures and design new molecules suitable for advanced applications. Expected outcomes are new methods and architectures that can ultimately yield devices that act at the molecular level.Read moreRead less

This project seeks to understand and exploit the rich photochemistry for an important class of electrically conducting polymers, namely polyanilines. Light stimulated electron transfer events will be employed in a wide range of exciting applications. The new fundamental knowledge gained will be used to design novel photochemical routes to functionalised polyanilines. The ability to produce solutions, films and especially nanoparticles of polyanilines as photo-catalysts should result in novel light-driven processes of industrial/environmental significance (eg. reduction of carbon dioxide), as well as new light-promoted electronic communication with important biological molecules.Read moreRead less
Controlled Supramolecular Assembly in Aqueous Molecular and Macroscopic Systems. This project uses benign and mainly bio-degradable materials to produce hydrogels which are remarkable new materials containing at least ninety-eight percent water which may be made into films. Similar films are proving to be valuable in covering wounds, particularly serious burns, and in greatly improving wound healing and tissue growth. They may also be useful in new coating and aircraft de-icing technologies. The ....Controlled Supramolecular Assembly in Aqueous Molecular and Macroscopic Systems. This project uses benign and mainly bio-degradable materials to produce hydrogels which are remarkable new materials containing at least ninety-eight percent water which may be made into films. Similar films are proving to be valuable in covering wounds, particularly serious burns, and in greatly improving wound healing and tissue growth. They may also be useful in new coating and aircraft de-icing technologies. These environmentally friendly materials are likely to find a multitude of uses as their development progresses. Young Australians involved in the project will gain experience in cutting edge science, its practical applications, and in international collaboration - a training essential to Australia's future prosperity.Read moreRead less
Light-activated Bioconjugates for Applications in Synthesis and Biosensing. This project will allow the Australian biotechnology industry to develop better diagnostic biosensors that are controlled using light, making them cheaper and faster than the current generation of electronically controlled biosensors. Improvements in the response time of biosensors can be a matter of life and death, for instance, during a surgical operation. The project will benefit the pharmaceutical industry as it will ....Light-activated Bioconjugates for Applications in Synthesis and Biosensing. This project will allow the Australian biotechnology industry to develop better diagnostic biosensors that are controlled using light, making them cheaper and faster than the current generation of electronically controlled biosensors. Improvements in the response time of biosensors can be a matter of life and death, for instance, during a surgical operation. The project will benefit the pharmaceutical industry as it will allow the making of so-called chiral drugs cheaper and safer but problems with the purity of chiral drugs have in the past caused serious side-effects such as in the tragic case of thalidomide.Read moreRead less
Selective Detection and Removal of Contaminants That Have an Adverse Impact on Australian Raw Sugar Quality. Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.

Sugar is Australia's 2nd largest agricultural crop with 80-85% exported earning $2 billion in export revenue. Whilst Australia is arguably the most reliable supplier of premium raw sugar the implementation of improved processing technologies by rivals has (and without appropriate research strategies will continue to) eroded some of the long-held Australian advantages.
Our innovative approaches will improve raw sugar quality, measurement methods, and allow new product development (value adding), enabling Australia to maintain its? world leading position. Importantly, our technologies enable improvements of specific quality issues (and potentially as yet unidentified issues), further differentiating the Australian product in the international marketplace.

In-field sensors for the detection of illicit drugs. Presumptive field test kits for illicit drugs analysis are typically based on chemical spot tests that produce a coloured product. While relatively easy to apply, such test kits (containing wet chemicals) produce inconclusive colour changes lacking sensitivity, and selectivity requiring a subjective assessment by the examiner. Despite these limitations, these test kits are in widespread use and are routinely used. This study aims to develop s ....In-field sensors for the detection of illicit drugs. Presumptive field test kits for illicit drugs analysis are typically based on chemical spot tests that produce a coloured product. While relatively easy to apply, such test kits (containing wet chemicals) produce inconclusive colour changes lacking sensitivity, and selectivity requiring a subjective assessment by the examiner. Despite these limitations, these test kits are in widespread use and are routinely used. This study aims to develop specific in-field sensors for the detection and identification of illicit drugs. This would significantly enhance the ability of Forensic Services staff to confirm the identity of seized material. Increased specificity would provide valuable early advice to investigators regarding the nature of a seizure and would reduce the likelihood of false positive results. Increased sensitivity would permit the analysis of trace amounts of material from individuals or locations related to an illicit drug consignment.Read moreRead less

This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work and simultaneously measure the very small forces that the machines generate. This will give Australian scientists access to a new technology for studying molecular machines.Read moreRead less
