Cover illustration: Scattered intensity distribution from an axial InAs1-xPx segment in an InAs nanowire recorded by nano-focused X-ray diffraction (see Keplinger, Mandl, Kriegner, Holý, Samuelsson, Bauer, Deppert and Stangl, pages 59-66). Presented are Qy/Qz slices of the measurement on the left-hand side and of the according simulated scattered intensity on the right-hand side.

A next-generation bimorph mirror with piezos bonded to the side faces of a monolithic substrate was created. When replacing a first-generation bimorph mirror suffering from the junction effect, the new type of mirror significantly improved the size and shape of the reflected synchrotron X-ray beam. No evidence of the junction effect was observed even after eight months of continuous beamline usage.

For the first time, planar X-ray refractive lenses have been fabricated by laser micromachining in 300 µm-thick single-crystal diamond. Tests at the ESRF ID06 beamline showed that the manufacturing quality is adequate to use such lenses as beam-conditioning elements at synchrotron radiation sources.

Deformation mechanisms of as-deposited and post-annealed Ti50.2Ni49.6, Ti50.3Ni46.2Cu3.5 and Ti48.5Ni40.8Cu7.5 thin films were investigated using in situ synchrotron X-ray diffraction technique. Results showed that initial crystalline phases determined the deformation mechanisms of all the films during tensile loading.

The structure of Ge quantum dots prepared by colloidal synthesis shows a dependence on the preparation route. Comprehensive characterization using both synchrotron radiation (X-ray absorption and X-ray diffraction) and in-house facilities (Raman and transmission electron microscope) shows metastable phase features of as-prepared and annealed Ge nanoparticles.

A series of Ni dithiolene complexes Ni[S2C2(CF3)]2n (n = −2, −1, 0) and an olefin adduct Ni[S2C2(CF3)2]2(C6H12) have been examined by extended X-ray absorption fine structure (EXAFS) and multiple-scattering analysis. The neutral complex is found `reduced' upon addition of olefin, presumably by olefin donating the electron density to the LUMO orbital.

Synchrotron radiation computed laminography has been in use in three-dimensional non-destructive imaging of flat objects for several years. A new set-up is proposed based on the traditional method but with the detector inclined at the same angle as the sample inclination to collect projections.

This study presents an approach to increase the sensitivity of lung computed tomography (CT) imaging by utilizing in-line phase contrast CT in combination with single-distance phase-retrieval algorithms and a dedicated image-processing regime. As demonstrated here, functional CT imaging can be achieved for the assessment of both structural alterations in asthmatic mouse lung tissue and the accumulation pattern of instilled barium-sulfate-labelled macrophages in comparison with healthy controls.
