Highlighted illustration

Cover illustration: Top right: an example of Laue diffraction patterns of a single crystal of calcium fluoride (30 mm diameter) (see Mukaide, Kajiwara, Noma and Takada, pages 484-488). The other three images are three-dimensional reconstructed images of part of the samples from section topographs recorded by step-scanning white X-ray section topography (top left and bottom right: 30 mm diameter and 30 mm thickness; bottom left: 60 mm diameter and 50 mm thickness). The shapes of a subgrain and a glide plane are illustrated by the yellow surface and the blue surface, respectively.

A new hard X-ray diffraction beamline at BESSY is now under user operation, using a 7 T multipole wiggler as a powerful source of X-rays with energies up to 30 keV. The beamline is intended for single-crystal diffraction and resonant scattering experiments for the study of ordering phenomena, phase transitions and materials science.

Small-angle X-ray scattering (SAXS) carried out using pinhole geometry and an area detector is a powerful and flexible technique, but subject to a number of limitations that can be greatly mitigated with relatively simple equipment and technique enhancements, as demonstrated on the ChemMatCARS SAXS/WAXS camera.

The rubber vulcanization process requires ZnO particles that hide the X-ray scattering of the filler. It is shown that ASAXS allows the determination of the filler structure factor which cannot be obtained by the usual SAXS method.

Energy scans at fixed momentum-transfers under specular X-ray reflectivity conditions near the LIII Cs+ resonance reveal the formation of a diffuse Gouy–Chapman layer at a charged aqueous surface, and also provide the anomalous f′ and f′′ terms of Cs ions in solution.

The Cu K-edge XANES spectra of several Cu(II) compounds have been analyzed within the multichannel multiple-scattering framework. The comparison between the experimental data and computations indicates that the experimental spectra can be accounted for by using two electronic configurations, 3d9 and 3d10\underline{L} (\underline{L} being a hole from the ligand). These results suggest that the two-channels (3d9 and 3d10\underline{L}) scheme is the general case for the K-edge XANES of divalent copper systems.
