Cover illustration: A 2.2 Å resolution electron density map from AcNiR S-SAD experiments at SOLEIL using [lambda] = 2.07 Å (see Doutch, Hough, Hasnain and Strange, pages 19-29). Two-thirds of the side chains could be automatically fitted.

This paper describes the design and construction of a new molten salt cell and furnace, which together allow individual cell components such as anodes and cathodes to be studied in situ using synchrotron-based energy-dispersive X-ray diffraction. The performance of this equipment is demonstrated by an in situ study of a model inert anode within an operational Fray–Farthing–Chen Cambridge titanium electrowinning cell, using the JEEP beamline at the Diamond Light Source.

A new radiotherapy technique, minibeam radiation therapy, combining submillimetric field sizes and a spatial fractionation of the dose is under development at the biomedical beamline of the ESRF. Here the therapeutic effectiveness of single-fraction minibeam radiation therapy on 9L gliosarcoma-bearing rats is assessed.

In coherent scattering from a material with only short-range order, it is shown that there exists an `intermediate-field' regime in which the ensemble averages of the scattered intensity and of the structure factor are equal. In addition, the ensemble-averaged temporal correlations of the intensity and of the structure factor are equal.

It is shown that a refractive lens can focus the initial X-ray free-electron laser pulses of duration 0.3 fs to the same size as for a monochromatic beam. A general semi-analytical method of calculating the propagation of XFEL pulses through a system of refractive lenses is developed.

A moiré pattern is observed by dividing the incident beam into two and formed by multiple Bragg–Laue interference fringes corresponding to the two incident beams. The coherency of X-rays from a bending-magnet beamline is evaluated using the moiré pattern.

Local tomography data from a set of multiscale measurements on a tumor vessel tree were quantitatively compared with global data, and algorithms were used to match the reconstructed absorption coefficients. The study shows that the systematic differences in the absorption coefficients between the local and the global data arise not only from the truncated projections but to a greater extent from the optical components of the detector used.

The presented experiments aimed to study the feasibility of XAS measurements on the solute in a nebulized solution. The results indicate that such measurements are possible, but that high solution concentrations and/or extended sampling times are required to achieve a good signal-to-noise ratio.
