This project will investigate the use plasmonic absorption of light in metal nanostructures to activate the selective oxidation/reduction of a gas molecule on a semiconductor nanoparticle. This concept will be used with the aim of developing a sensing technique capable of measuring ultra-low concentrations (ppb) of breath markers for lung cancer detection. It is expected that porous sensing films of semiconductor and metal nanoparticles with well-defined light absorption properties will be fabricated. Superior selectivity will be achieved by matching the wavelength of the absorbed light with the required activation energy for oxidation/reduction. Successful outcomes will enable multi-analyte fingerprint identification by on-chip devices with applications ranging from portable medical diagnostics to national security.Read moreRead less
Vapour phase detection of chemical warfare agents. This project aims to create luminescent plastic optoelectronic materials that can detect airborne chemical warfare agents, particularly nerve agents. Such agents are often odourless and invisible at lethal concentrations, so technology must detect and identify them before exposure. The intended outcomes are design rules for sensitive and selective materials that can be used in a handheld infield detector to sense chemical warfare agents based on ....Vapour phase detection of chemical warfare agents. This project aims to create luminescent plastic optoelectronic materials that can detect airborne chemical warfare agents, particularly nerve agents. Such agents are often odourless and invisible at lethal concentrations, so technology must detect and identify them before exposure. The intended outcomes are design rules for sensitive and selective materials that can be used in a handheld infield detector to sense chemical warfare agents based on the materials’ photophysical properties, and new analytical methods and sensing protocols. This research will be of interest to security agencies in Australia and internationally, and will better protect our military.Read moreRead less
Non-equilibrium material phases. This project aims to synthesise and characterise exotic materials produced in the laboratory under conditions that replicate those inside planets and stars. Highly non-equilibrium processing methods are needed to find entirely new material forms of elements and compounds created under extreme pressure and temperature. The project will use its laser-based synthesis method to explore and understand the non-equilibrium pathways and develop new materials. Understandi ....Non-equilibrium material phases.

By enabling the modulation of infrared and terahertz signals, the intended outcome is a platform for imaging applications, detection of chemical composition of objects, and future high-bandwidth communications. Using microfabrication techniques, the project plans to create metamaterials integrated with micro-electro-mechanical systems, which dynamically vary their electromagnetic properties. This technology would enable the creation of new devices that can controllably absorb, reflect or transmit infrared and terahertz signals.Read moreRead less

Expected outcomes of this project include new and enhanced knowledge of physics of light-matter interactions, developing an efficient, clean source of excited metastable atoms, and integrating that source into the Australian National Facility for dating geological samples. This should provide significant benefits, such as significant improvement of operational efficiency and productivity of that facility.Read moreRead less
