X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) are complementary techniques for investigating the structure of materials. XRD probes long range order and XAFS probes short range order. We have combined the two techniques at one synchrotron beamline, X18A at the NSLS, allowing samples to be studied in a single experiment.

XRD characterization of multilayered systems
Thin Solid Films, 1993Abstract An innovative procedure has been devised for the processing of X-ray diffraction data from thin films and layered samples, using the conventional Bragg-Brentano geometry. Conventional phase analysis procedures always consider the sample as a homogeneous set of crystals with random orientation; this assumption can lead to severe errors when ...

Advances in X-ray Analysis, 1993
PC software for XRD is strongly influenced by the cost of the hardware. Contrasted to mainframe and mini platforms, PC's are essentially free, or at least much less expensive than maintenance contracts for the hardware we've used in the past. But when we get our own computer, we discover that much more time goes into tasks others did before such as ...

XRD Investigation of Binary Alloy Solidification
Annals of the New York Academy of Sciences, 2009The solidification of two binary alloys, In–10Sn and Sn–13Pb, has been investigated by X‐ray diffractometry (XRD) at high temperatures. The high‐temperature X‐ray camera, which was mounted on a diffractometer, had a sample holder suitable for molten metals and operated in a controlled Ar atmosphere.

OpenID identity discovery with XRI and XRDS
Proceedings of the 7th symposium on Identity and trust on the Internet, 2008The work examines the identity discovery problems that needed to be addressed by the OpenID 2.0 protocol in order to enable a user-centric Internet identity layer. The paper illustrates how the OASIS XRI and XRDS specifications were applied to help solve these identity discovery challenges.

XRD and Synchrotron-Based XRD Study of Chalcopyrite Leaching Catalyzed by Silver Ions
2020Silver ion can effectively improve the bioleaching efficiency of chalcopyrite, and the mechanism of the process is still in controversy. In this study, leaching experiments, X-ray diffraction (XRD), and synchrotron radiation X-ray diffraction (SR-XRD) were conducted to investigate the intermediate of chalcopyrite in chemical leaching and bioleaching ...

High temperature XRD of Cu2GeSe3
AIP Conference Proceedings, 2015The Cu2GeSe3 is prepared by solid state synthesis method. The high temperature XRD has been done at different temperature from 30 °C to 450 °C. The reitveld refinement confirms Cu2GeSe3 phase and orthorhombic crystal structure. The lattice constants are increasing with increase in the temperature and their rate of increase with respect to temperature ...

In-Situ XRD Investigation of Bauxite Dehydroxylation
2018Thermal activation of bauxite has been proposed to enable bauxite dissolution at a reduced digestion temperature and also to reduce the organic content in the liquor. Research has been carried out on phase transformation of its main hydroxide components (gibbsite, boehmite and kaolinite) during calcination.
