Spectroscopy of Complex Fluids in Flow. Complex fluids are composed of polymers and nano-particles in solution. Under flow these fluids may undergo dramatic molecular and nano-particle orientational and spatial ordering that give rise to a fascinating range of rheological behaviour. This project will use state of the art fluorescence spectroscopy which is able to resolve the orientation of single molecules combined with novel rheo-optic methods to characterise flow induced ordering in these flui ....Spectroscopy of Complex Fluids in Flow. Complex fluids are composed of polymers and nano-particles in solution. Under flow these fluids may undergo dramatic molecular and nano-particle orientational and spatial ordering that give rise to a fascinating range of rheological behaviour. This project will use state of the art fluorescence spectroscopy which is able to resolve the orientation of single molecules combined with novel rheo-optic methods to characterise flow induced ordering in these fluids. The flow induced orientation, spatial distribution and nano-particle/macromolecule interactions will be quantified. Theoretical deficiencies in describing complex fluid flow will be reconciled. The experimental insight gained will be exploited to produce novel molecularly ordered materials.

This research will develop a new x-ray diffraction technique for characterization of silicon-germanium-carbon semiconductor alloys. These are the basis for the new generation, ultra-high speed broadband telecommunication devices. The research will establish a new theoretical methodology for fundamental studies of x-ray scattering phenomena in compound strain-compensated materials. The experiments will be carried out using the state-of-the-art laboratory and synchrotron radiation facilities in Australia, Japan and France. The project involves direct collaboration with IHP Germany, the world-leading semiconductor developer. Highly qualified postgraduate students will be extensively trained in modern synchrotron experiments, x-ray diffraction theory and semiconductor technology during the project.Read moreRead less
Fabrication of complete photonic band gap structures by two-photon polymerization and subsequent infiltration with high refractive index materials. The ability to shrink photonic circuits by orders of magnitudes by the integration of photonic crystals offers many stimulating possibilities for novel device designs. A speculative view is that this miniaturisation can have a similar impact to that experienced in electronic components in the 1960s. However, the fabrication of 3D photonic crystals re ....Fabrication of complete photonic band gap structures by two-photon polymerization and subsequent infiltration with high refractive index materials. The ability to shrink photonic circuits by orders of magnitudes by the integration of photonic crystals offers many stimulating possibilities for novel device designs. A speculative view is that this miniaturisation can have a similar impact to that experienced in electronic components in the 1960s. However, the fabrication of 3D photonic crystals remains a major challenge and the development of new, flexible, and fast nano-fabrication techniques is vital. The realization of an innovative technique for the fabrication of 3D complete photonic band gap structures as it is suggested will make an essential contribution to the emerging field of all-optical tele- and data-communications and will deliver major economic benefit to Australia.

Applying advanced synchrotron radiation-based techniques to determine the connection between the geometric and electronic structure of semiconductor nanocrystals. As the dimensions of nanocrystals become small unique optical and electronic properties are observed, forming the basis of many new technologies. The properties of interest depend on the fine-scale, local details of the nanocrystal structure, which may differ considerably from bulk-like. Advanced synchrotron radiation techniques wil ....Applying advanced synchrotron radiation-based techniques to determine the connection between the geometric and electronic structure of semiconductor nanocrystals. As the dimensions of nanocrystals become small unique optical and electronic properties are observed, forming the basis of many new technologies. The properties of interest depend on the fine-scale, local details of the nanocrystal structure, which may differ considerably from bulk-like. Advanced synchrotron radiation techniques will be used to investigate the relationship between the local geometric and electronic structure of semiconductor nanocrystals. Insight will be provided to their formation and stability, and the important mechanisms of their unique optical and electronic properties will be identified. Such fundamental information is necessary to facilitate innovative application of future nanocrystal technology.Read moreRead less
