Morphological characterization of aqueous tin oxyhydroxide gel
Light scattering, electron microscopy and X-ray diffraction are used to determine the morphology and size of particles in diluted aqueous gel of tin (IV) oxyhydroxide. Data show that the gel is composed of spherical 2-3 ...
X-ray photoelectron spectroscopy, x-ray absorption spectroscopy, and x-ray diffraction characterization of CuO-TiO2-CeO2 catalyst system
(American Institute of Physics (AIP), 2001-07-01)
X-ray photoelectron spectroscopy (XPS), x-ray diffraction (XRD), and x-ray absorption spectroscopy (XAS) techniques have been applied to characterize the surface composition and structure of a series of CuO-TiO2-CeO2 ...
Piezoelectric coefficients d(14), d(16), d(34) and d(36) of an L-arginine hydrochloride monohydrate crystal by X-ray three-beam diffraction
(Blackwell PublishingOxfordInglaterra, 2006)
The solid solution between platinum and palladium in nature
Chemical and structural data are reported for platinum-palladium intermediates from two nuggets found at Corrego Bom Sucesso, Minas Gerais, Brazil. Three grains with simple stoichiometries (i.e. PtxPd1 -x with x ∼0.67, ...

Crystallography and the liquid crystal phase: a new approach to structural studies on a thermo-tropic smectic Schiff base
(Taylor & Francis Ltd, 2018-01)
In spite of the apparent contradiction between ‘liquid crystals’ (LC, materials exhibiting some degree of disorder) and ‘crystallography’ (a paradigmatic ordered kingdom), X-ray diffraction (XRD) studies make a substantial ...
Copper ore type definition from Sossego Mine using X-ray diffraction and cluster analysis technique
(Escola de MinasOuro Preto, 2013-08-02)
This paper presents the classification of 110 copper ore samples from Sossego Mine, based on X-ray diffraction and cluster analysis. The comparison based on the position and the intensity of the diffracted peaks allowed ...
Characterization of nickel doped Zn7Sb2O12 spinel phase using Rietveld refinement
(J C P D S-int Centre Diffraction Data, 2003-09-01)
Zn7Sb2O12 is known to adopt an inverse spinel crystal structure, in which Zn2+ occupies the eight tetrahedral positions and Sb5+ and Zn2+ randomly occupy the 16 octahedral positions. Samples of Zn7-xNixSb2O12 (X = 0, 1, ...
