A review. Ultrafast x-ray techniques using diffraction and absorption are discussed with an emphasis on the absorption techniques. Ultrafast x-ray sources and detectors for use in x-ray absorption spectroscopy are also reviewed. [on SciFinder (R)] ...
Analyse des diélectriques commerciaux : fluorescence X, Infrared absorption, EDX, X-ray Diffraction. Détermination des éléments, déduction des composés par détermination des phases de ceux ci. Tout ceci afin de déterminer les éléments responsables de l’adh ...
Hexafluoro-2-butyne, CF(3)Cequivalent toCCF(3), reacts with the triangulo-clusters [Pt-3 (mu-CO)(3)(PR3)(3)] to give the diplatinum(o) compounds [Pt-2(CO)(2)(PR3)(2)(mu-eta(2):eta(2)-CF(3)Cequivalent toCCF(3))] {PR3=PPh3 (1), PBzPh(2) (2), PCy3 (3), (PPr3) ...
Electrode stability, interdiffusion, phase purity and deviation from stoichiometry at the PZT-electrode interface are key issues in PZT thin film integration. This article highlights the use of transmission electron imaging combined with energy dispersive ...
Specimen charging under X-ray illumination is a well known phenomenon that can seriously obstruct the analysis of insulating samples. Synchrotron X-PEEM spectromicroscopy can reach a lateral resolution of 20 nm, 1-2 orders of magnitude larger than electron ...
ZnO and AlN, which exhibit the wurtzite structure, were deposited onto metal coated SiO2 substrates by sputtering. X-ray diffraction (XRD) indicated that the films contained no second phases and exhibited an [0001] texture. Transmission electron microscopy ...
GaAs/AlxGa1-xAs multiple-quantum-well (MQW) structures with identical well thicknesses but with different Al contents x in the barrier (x almost-equal-to 0.1, 0.2, 0.45, and 1) were grown by molecular-beam epitaxy to study the impurity-induced disordering ...
Complex perovskite A(B'B'')O3 ceramics with various degrees of B-site order have been structurally and spectroscopically characterized by means of x-ray diffraction, transmission electron microscopy, and infrared reflectivity. In Ba(Fe1/2Nb1/2)O3 and Pb(Fe ...
The deactivation of supported nickel catalysts by coking is an important technological subject for many chemical processes, especially when high concentrations of unsaturated hydrocarbons are present in the feed gas. Here, the reversible segregation of Ni ...
