Ms Tingting SONG (RMIT University)26/11/2015, 13:30Advanced MaterialsPosterDealloying is used to fabricate nanoporous metals, and is a process where less noble components (e.g. Al) in the precursor (e.g. AlCu) are dissolved, leaving the nobler elements (e.g. Cu) to a nanoporous structure. Nanoporous Cu is desired in lithium-ion batteries as current collectors, which can provide large surface area for active materials. From the perspective of phase evolution, it was...Go to contribution page

Dr Peter Kappen (Australian Synchrotron)26/11/2015, 13:30Advanced MaterialsPosterCarbon nanotubes (CNTs) have attracted significant attention and in many cases they have been used as a single-function additive to modify a specific property of a material, such as the mechanical strength of a composite. It is interesting to extend those properties by coupling them with properties of other materials, thus generating systems that can serve more complex functions (e.g.,...Go to contribution page

Dr Anton Maksimenko (Australian Synchrotron)26/11/2015, 13:30ImagingPosterThe Imaging and Medical Beamline (IMBL) of the Australian Synchrotron (AS) is now becoming one of the most advanced instruments of this type in the world. It is designed to provide a wide variety of imaging techniques including but not limited to the in-line and analyzed phase contrasts, monochromatic and pink beam imaging. Three beamline’s enclosures at various distances, when combined with...Go to contribution page

Susan Cumberland (Australian Synchrotron)26/11/2015, 13:30Energy MaterialsPosterUranium (U) is internationally important as a low carbon energy source, however, its extraction and radioactive waste legacies require continuing research into the factors controlling U mobility. Uranium mobility is strongly influenced by its oxidation state: U(VI) (e.g., U(VI)-carbonate) is more soluble than U(IV), which mineralises as coffinite [USiO4] or uraninite [UO2]. By identifying the...Go to contribution page

Mrs Priyanthi Hapugoda (CSIRO)26/11/2015, 13:30Earth and EnvironmentPosterEstablishing health impacts of urban dust require quantitative particle size and composition information. For the coal industry, dust is a significant responsibility. Coal dust originates from mining, transportation and coal usage. Public concern is greatest where mines are in proximity to towns, rail corridors and ports. Although coal may only be one of the dust constituents, there is an...Go to contribution page

Nigel Kirby (Australian Synchrotron), Stephen Mudie (Australian Synchrotron), Vesna Samardzic-Boban (Australian Synchrotron)26/11/2015, 13:30Beamlines, Instrumentation and TechniquesPosterVirtualisation technologies have been introduced to control systems at the Australian Synchrotron (AS) and results of recent virtualisation on a couple of beamlines are presented here. Reasoning and motivation for having beamline Virtual IOCs (Input Output Controller’s) are: replacement of aging computers with physical ones is becoming expensive, desire for reduction of computing...Go to contribution page

Dr Jason Paxman (Department of Biochemistry and Genetics, La Trobe Institute for Molecular Science, La Trobe University, Melbourne, VIC)26/11/2015, 13:30Structural BiologyPosterAutotransporter (AT) proteins are important virulence factors and constitute the largest family of secreted and outer membrane proteins in Gram-negative bacteria. Despite their importance in bacterial pathogenesis there are only 12 structures of AT α-domains in the PDB and their mechanisms of action are poorly understood. Most structurally determined AT α-domains were found to be built upon...Go to contribution page

Dr Tilo Soehnel (The University of Auckland)26/11/2015, 13:30Advanced MaterialsPosterLayered oxide materials that combine unusual intermetallic architectures and transition metal oxides similar to naturally occurring mineral architectures are promising candidates for the study of strongly correlated-electron systems. One of the key benefits of systems that contain naturally occurring mineral structures is they provide a widely characterized platform to stabilize new...Go to contribution page

Dr David Aragao (Australian Synchrotron), Dr Lenneke Jong (Australian Synchrotron)26/11/2015, 13:30Beamlines, Instrumentation and TechniquesPosterThe MX1 and MX2 beamlines at the Australian Synchrotron are single crystal diffraction beamlines, servicing the needs of protein and chemical crystallography communities. We have developed a web-based user interface for driving data collections, called YAIBEX (Yet Another Integrated Beamline Environment for Crystallography). This system is designed to replace the collect tab on the SSRL BluICE...Go to contribution page
