Cover illustration: Images of X-rays specularly reflected from an Al2O3 (012)-water interface (see Fenter, Catalano, Park and Zhang, pages 293-303). Individual images (left, with a logarithmic colour map with red indicating the highest intensity) show a characteristic splitting of the reflected beam associated with the tilting of the specular truncation rod of a mis-cut surface, as seen when images are compiled in a Qz-Q// reciprocal-space intensity map (right). The regions near the Bragg peaks are suppressed.

Synchrotron-based X-ray fluorescence was used to examine the relative concentrations of metals in Arabidopsis thaliana seeds and as the basis of a high-throughput technique for the identification of metal mutants.

A Ge pixel array detector with 100 segments was applied to fluorescence X-ray absorption spectroscopy, probing the local structure of high-temperature superconducting thin-film single crystals (100 nm in thickness).

Einstein and Debye models for EXAFS parallel mean-square relative displacement are critically reviewed and extended to the perpendicular mean-square relative displacement.

A compact diffraction-reaction chamber has been employed to investigate the chemical dynamics at the combustion front of a selected series of refractory metal carbides and di-borides from their constituent element reactants as well as binary products from B4C as a reactant.

Theory is developed for emission of transition radiation (TR) by low-energy storage-ring synchrotrons. Since such TR is used mostly for performing X-ray lithography (XRL), the sensitivity of the XRL photoresist is also formulated.

The focal sharpness of a Bragg–Fresnel lens (Laue diffraction geometry) can be improved by decreasing the height, and hence the width, of the Fresnel zones. The impact of this approach on the signal-to-background ratio of the focused spot and other properties is explored and found to be less than with ordinary Fresnel lens optics (in the absence of Bragg diffraction).
