Dr Andrew Martin (ARC Centre for Excellence for Advanced Molecular Imaging, School of Physics, University of Melbourne)27/11/2015, 13:30ImagingPosterFourier-transform holography is an established method of high-resolution coherent x-ray imaging, but is limited by the need to fabricate highly specific reference structures. Traditional reference structures must be coplanar with the sample, and are typically fabricated along with the sample. We have recently developed the technique of holography using an arbitrary customizable reference,...Go to contribution page

Prof. Christopher Thomas Chantler (University of Melbourne)27/11/2015, 13:30Beamlines, Instrumentation and TechniquesPosterExciting fundamental problems and advanced applications have emerged in X-ray Spectroscopy. Accuracy of absorption coefficients to 0.02% have led to insights into atomic form factors[1], XAFS dynamical bonding[2], electron inelastic mean free paths[3] and nanoroughness[4], with technological offshoots into detector and synchrotron diagnostics. As a consequence, the accurate characterization of...Go to contribution page

Mrs Iman Jabaz (Department of Chemical Engineering, Monash University), Dr Lian Zhang (Deaprtment of Chemical Engineering, Monash University)27/11/2015, 13:30Earth and EnvironmentPosterOxy-fuel combustion is the burning of coal in the mixture of recirculated flue gas and high-purity oxygen, so as to reduce the carbon emission from coal-fired power plant. The fly ash - related fouling and corrosion are some of the most crucial issues encountered in this process. Understanding tube corrosion in this new combustion process is pivotal for a successful adoption of this technology...Go to contribution page

Dr Nirawat Thammajak (Synchrotron Light Research Institute (SLRI), Thailand)27/11/2015, 13:30Earth and EnvironmentPosterX-ray absorption near-edge spectroscopy (XANES) can be used to study oxidation state of dilute system such as transition-metal defect in solid-state samples. In blue sapphire, Fe and Ti are key elements that caused the blue colour. Inter-valence charge transfer (IVCT) between Fe2+ and Ti4+ has been proposed to describe the optical colour's origin. However, existence of the divalent iron...Go to contribution page
