Conceptual frameworks arising in the physical sciences, such as non-equilibrium statistical mechanics and thermodynamics, synergetics, chaos and dynamical systems theory, are seminal in the emerging science of complexity. This study will lay the groundwork for a network to link Australian and overseas research on these fundamental concepts, and their application within the context of entropy-producing systems vital to the long-term sustainability of the earth - oceans, atmosphere, biosphere, CO2-free energy production, space and solar environment. The network would facilitate the development of young investigators and be linked into wider complex systems networks such as the CSIRO Centre for Complex Systems Science.Read moreRead less
Nanotribology and Nanorheometry: A Fundamental Study of the Dynamic Interactions of Particles and Surfaces at the Molecular Level. Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces.

Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.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. 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. 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

Efficient and tailored supercontinuum generation using dispersion management. Imagine a laser beam, but not with just one colour, but containing all colours. The light beam thus looks white, somewhat like a search light, except that it is much brighter. We now know how to generate such bright white beams of light, but it is expensive, requiring a small specialized laboratory full of equipment. Through a better understanding, we will make it easier and cheaper to generate these light beams. All k ....Efficient and tailored supercontinuum generation using dispersion management.

We now know how to generate such bright white beams of light, but it is expensive, requiring a small specialized laboratory full of equipment. Through a better understanding, we will make it easier and cheaper to generate these light beams. All kinds of applications that have been known for years, such as medical imaging and chemical analysis, then suddenly become practical. We anticipate that in the future these bright white light beams will be used on a routine basis in Australian hospitals and industry. Read moreRead less
Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently avai ....Optical fibre devices for sideways delivery of laser light during keyhole surgery. Mulitmode optical fibres are typically used to deliver high power laser light which is emitted from the end of the fibre to irradiate tissue during surgery. For intravenous delivery of laser light in the treatment of cardiac fibrillation (heart flutter) we require a sideways-directed illuminating beam. However reliable methods of delivering high power laser light in a sideways-directed beam are not currently available. Using the ultraviolet laser fibre processing expertise already developed at Macquarie University, we propose to develop and characterise novel fibre-based devices which would allow controllable delivery of light sideways.Read moreRead less

This project is expected to bring significant scientific, economic and social benefits. We will develop a number of techniques for the controlled growth of nanowires and making functional nanoscale systems such as nanosensors. The nanosensors will have important applications in chemistry and biology. Some chemical species can be detected by nanosensors on molecular scale. The nanosensors could be used for early diagnostics of cancer disease, detection of viruses, and genomic DNA screening. The nanosensors could also provide a molecular tool for probing living cells without destroying them, through which we can track life within cells in real time.Read moreRead less
