The experiment found that, surprisingly, rather than being stochastic, the X-ray induced electron dynamics in C60 are highly correlated, extending over hundreds of unit cells within the crystals1.
The Evolution of Silica Nanoparticle-polyester Coatings on Surfaces Exposed to Sunlight Vi Khanh Truong1, Miljan Stefanovic1, Shane Maclaughlin2, Mark Tobin3, Jitraporn Vongsvivut3, Mohammad Al Kobaisi1, Russell J. Crawford4, Elena P. Ivanova1 1School of Science, Faculty of Science, Engineering and Technology, Swinburne University of Technology, 2BlueScope Steel Research, 3Infrared Microspectroscopy Beamline, Australian Synchrotron, 4School of Science, College of Science, Engineering and Health, RMIT University Two types of surfaces, polyester-coated steel and polyester coated with a layer of silica nanoparticles, were studied. Both surfaces were exposed to sunlight, which was found to cause substantial changes in the chemistry and nanoscale topography of the surface.
In Situ Neutron Powder Diffraction Using Custom-made Lithium-ion Batteries William R. Brant1, Siegbert Schmid1, Guodong Du2, Helen E. A. Brand3, Wei Kong Pang2,4,5, Vanessa K. Peterson4, Zaiping Guo2,5, Neeraj Sharma6 1School of Chemistry, University of Sydney, 2Institute for Superconducting & Electronic Materials, University of Wollongong, 3Australian Synchrotron, 4Australian Nuclear Science and Technology Organisation, 5School of Mechanical, Materials, and Mechatronic Engineering, University of Wollongong, 6School of Chemistry, University of New South Wales We describe the design and construction of an electrochemical cell for the examination of electrode materials using in situ neutron powder diffraction (NPD). We briefly comment on alternate in situ NPD cell designs and discuss methods for the analysis of the corresponding in situ NPD data produced using this cell.
