Chemical analysis is a vital activity in our society, which is to a large extent confined to scientific laboratories and carried out with complex instrumentation. The breakthrough technology envisioned in this proposal will pave the way for simple, low-cost tests which can be used by non-scientists. The development of small, portable sensors for applications ranging from pollution monitoring to health testing, will enable ordinary people to gain knowledge about the concentrations of molecular compounds in their environments and in themselves. This will stimulate economic and social benefits related to environmental testing and early disease diagnosis and generate new commercial opportunities for the Australian biotechnology industry.Read moreRead less
Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less

This project aims to establish an in situ transmission electron microscope that will allow the atomic scale imaging of materials, while simultaneously measuring physical, chemical, electrical and optical properties, using a novel combination of cutting edge in-situ sample holders and an instrument mounted laser system. The instrument will be optimised for imaging of dynamic phenomena and the combination of spatial resolution in the picometre scale, with microsecond level temporal resolution will be unique. The instrument will accelerate research into hydrogen production and carbon dioxide transformation, and thus support Australia's move to a more sustainable economy. Read moreRead less

Electrostatic Catalysis: guiding reactive interfaces using electric fields. This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies.

This project seeks to gain quantitative understanding of the role of electrostatics over chemical processes. Chemical transformations of organic compounds at interfaces underpin some of the most important processes, from the production of fine chemicals for pharmaceuticals to assisting bio-degradation of pollutants in clean technologies. Recent computational studies suggest that by applying oriented electric fields at interfaces, the rate and the selectivity of chemical processes can be altered at will. The project intends to test these theoretical findings. The knowledge generated by this research may translate into new technologies for the fine-chemical and biotechnology industries.Read moreRead less
Gelled electrolyte materials for toxic gas sensing. This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design. Amperometric gas sensors are commonly employed to monitor oxygen and toxic gas levels, but the technology used is still based on a ....Gelled electrolyte materials for toxic gas sensing. This project aims to develop and implement an alternative approach to the current methods of monitoring of oxygen and toxic gas levels. The aim is to use novel gelled electrolytes based on ionic liquids and polymers, combined with miniaturised sensor devices, to create a robust membrane-free and spill-less design. Amperometric gas sensors are commonly employed to monitor oxygen and toxic gas levels, but the technology used is still based on a 1950s design. The expected outcome of the project is to make fundamental advances in the design of materials that are not affected by humidity changes and which impart selectivity towards particular gases. This will provide the basis for a new generation of low-cost, miniaturised, selective sensors for use in applications such as wearable toxic gas sensors, and as leak detectors on hydrogen-powered vehicles.Read moreRead less
