The project aims to develop a novel way to measure the state of soils and improve the perception of soft ground robots by combining advances in sensor development with granular physics. The project expects to produce new insights in geotechnical engineering by utilising innovative sensors compliant with the surrounding medium, thus improving measurements across broader deformation conditions than existing technologies. Expected outcomes include an increased ability to prevent soil failures by utilising these sensors to monitor stress levels underground. This should provide significant benefits for saving critical infrastructure from environmental and geotechnical failures, including landslides, tunnel collapses, and tailings dam damages.Read moreRead less
The Interface of Oil-in-Water Emulsions. The interface between two immiscible liquids controls many phenomena including the formation and properties of emulsions, the nature of many chemical separation processes and the behaviour of biological systems. There are few methods to study such interfaces and most of these are susceptible to trace contamination by adventitious surfactants, but emulsions with their large surface area avoid this problem. Significant advances are possible with the new Aus ....The Interface of Oil-in-Water Emulsions. The interface between two immiscible liquids controls many phenomena including the formation and properties of emulsions, the nature of many chemical separation processes and the behaviour of biological systems. There are few methods to study such interfaces and most of these are susceptible to trace contamination by adventitious surfactants, but emulsions with their large surface area avoid this problem. Significant advances are possible with the new Australian technique of electroacoustics, complemented by neutron scattering, nmr, rheological and dielectric response measurements on concentrated emulsions. Our surfactant-free emulsions provide a fundamental breakthrough in such studies, leading to new materials from nanostructures.Read moreRead less
Poly-crystalline Thin Films for LASER Applications. This project is based on a recent discovery which reports LASER emission in disordered media such as polycrystalline ZnO. This behaviour appears to be related to the crystallographic properties of ZnO (wurztite) material. Using a novel deposition process the defect density, size of crystallites and macroscopic orientation within such thin films will be controlled independently. This will provide an opportunity to study the fundamental basis of ....Poly-crystalline Thin Films for LASER Applications.

This behaviour appears to be related to the crystallographic properties of ZnO (wurztite) material. Using a novel deposition process the defect density, size of crystallites and macroscopic orientation within such thin films will be controlled independently. This will provide an opportunity to study the fundamental basis of such behaviour. In conjunction with this the development of structure in similarly produced GaN (wurztite) films will be examined. This work should also provide practical information concerning the potential performance of LASER devices based on disordered materials.Read moreRead less

Laser Spectroscopy of Molecular Electronic Components. Electronic devices such as computer memory have been getting smaller and smaller for decades, yet soon devices will need to be constructed from single molecules. Single molecules behave very differently to copper conductors and silicon chips. To understand the behaviour of molecular electronic devices such as molecular wires, switches and diodes, one needs to isolate them under rigorously reproducable conditions.

Single molecules behave very differently to copper conductors and silicon chips. To understand the behaviour of molecular electronic devices such as molecular wires, switches and diodes, one needs to isolate them under rigorously reproducable conditions. We will study molecular electronic devices in this way, providing rigorous support to Australia's growing expertise in this field.Read moreRead less
Molecules as probes of the interstellar medium. It is one of the greatest challenges in Nature is to remotely identify what is in space. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown, implying that there are many more molecules in space than we know about. With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab. Conversely, identification of these features will provide the tools to u ....Molecules as probes of the interstellar medium.

With a stronger understanding of space chemistry, we could predict what should be there and verify it in the lab.

In this project we combine skills in spectroscopy and astronomy to make these molecules in the laboratory, measure their spectra and thereby identify unknown molecules in space.Read moreRead less
Optical Spectroscopy of Extraterrestrial Molecules. Space is not empty. In the vast regions between stars is a complex soup of molecules. Some of these molecules get incorporated into meteorites and find their way to Earth where they can be identified. Analysis has yielded amino acids; the building blocks of life, but these molecules do not match what we know about the interstellar regions. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown. ....Optical Spectroscopy of Extraterrestrial Molecules. Space is not empty.

Analysis has yielded amino acids; the building blocks of life, but these molecules do not match what we know about the interstellar regions. Interstellar molecules are identified by their spectra, but many features in these spectra are unknown. Could they be caused by the missing molecules? In this project we combine the skills of three spectroscopists, each expert in different areas, in an attempt to make these molecules in the laboratory, measure their spectra and thereby identify these unknown molecules that are in space.Read moreRead less
