Cover illustration: Multi-modal X-ray images of bee, moth and lavender flower with three contrast mechanisms: attenuation contrast, differential phase contrast and dark-field contrast (see Bech, Bunk, David, Ruth, Rifkin, Loewen, Feidenhans'l and Pfeiffer, pages 43-47). Images are recorded at the Compact Light Source, an X-ray source based on inverse Compton scattering, the first of its kind. Phase contrast and dark-field images are obtained with a grating interferometer.

Lattice vibrations have been investigated in TiB2, ZrB2 and HfB2 by temperature-dependent EXAFS experiments. Data clearly show that the EXAFS oscillations are characterized by an anomalous behavior of the Debye–Waller factor of the transition-metal–boron pair.

A pressure study of the α-ReO2 structure up to 1.2 GPa using synchrotron X-ray powder diffraction and X-ray absorption spectroscopy is reported for the first time. To study the α-ReO2 phase under hydrostatic pressure, a new boron carbide anvil pressure cell that can be used in absorption and diffraction X-ray experiments in any synchrotron radiation facility has been developed and built.

Using X-ray fluorescent computed tomography (XFCT), the in vivo and ex vivo cerebral distribution of a stable-iodine-labeled cerebral perfusion agent has been recorded in the brains of mice. Results highlight the sensitivity of XFCT and its considerable potential to evaluate cerebral perfusion in small animals without using radioactive agents.

The Brazilian Synchrotron Light Laboratory is the only synchrotron radiation source in Latin America. Here the design, technical set-up and experimental parameters of the first wiggler macromolecular crystallography beamline (MX2) at this synchrotron source are described. Parameters of the X-ray diffraction data sets collected at the MX2 are also provided.

A pre-focused X-ray beam has been used to illuminate a single-bounce capillary in order to generate a high-flux X-ray microbeam at the BioCAT undulator X-ray beamline at the Advanced Photon Source. The combined optical arrangement makes it suitable for many microprobe fluorescence applications and micro-XANES experiments for biological samples.

A method for positioning diamond anvil cell samples at a centre of rotation is described and evaluated, after which the practice of rocking properly centred polycrystalline samples is examined. These selected techniques are crucial to optimizing the quality of data, and hence the accuracy of structural parameters, obtained from microscopic samples submitted to extreme pressure conditions.
