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
Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. 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 ....Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. 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
New Polymers for Cellulose-based Bioplastics. We will design new cellulose derivatives by combining carefully engineered synthetic polymers to cellulose. We will explore the fundamental science underpinning the manufacture of these bioplastics, and apply the concept to the design of two new materials, with (super)hydrophobic and antibacterial properties. These materials have the potential to replace synthetic plastics, which comprise one of the major outputs of the chemical industry worldwide. P ....New Polymers for Cellulose-based Bioplastics.

We will explore the fundamental science underpinning the manufacture of these bioplastics, and apply the concept to the design of two new materials, with (super)hydrophobic and antibacterial properties. These materials have the potential to replace synthetic plastics, which comprise one of the major outputs of the chemical industry worldwide. Plastic is present everywhere in human life, but its manufacture and disposal have a strong negative impact on the environment; the new materials manufactured in this project are viable alternatives to plastics, and are sustainable from a production and disposal point of view.Read moreRead less

There can be no doubt that protecting Australia's borders from the dual threats of terrorism and illicit drugs is of paramount importance to continuation of our well-being and way of life. Our chemical sensors are simple hand-held or remote chemical listening sensors, which will have the ability to sense the presence of characteristic chemical vapours associated with explosives and illicit drugs. The simplicity and low cost of the chemical listening allows for installation at key locations -e.g. transport hubs, shipping containers, airports etc as well as placement within clandestine drug laboratories.Read moreRead less

This application seeks to exploit our established lead in the measurement of diffuse scattering from disordered materials and its analysis using large-scale computer simulations. Many industrially important materials such as ceramics, superconductors, catalysts, electro-optical materials and minerals owe their special properties to the disorder in their structure. This disorder causes diffuse X-ray scattering which can be probed using synchrotron X-rays and powerful computers to reveal details about the material's nanoscale structure. The new methodology being developed will enhance our detailed understanding of the relationships between structure and properties in materials and help promote the design of new materials.

Polymer Globules: Beyond the Homopolymer Model. Polymers are long chainlike molecules which play a crucial role in many aspects of our lives. As plastics they represent the most versatile and ubiquitous of man-made materials. Moreover, all living things depend on polymers for the structure of their cells and for the inheritance and function through DNA and proteins. Despite their importance our understanding of polymers is rather limited. The research funded by this proposal will enable us to ....Polymer Globules: Beyond the Homopolymer Model.
