Cover illustration: Two-dimensional grazing-incidence X-ray diffraction pattern from a 15 nm-thick rubrene crystalline thin film grown on the surface of a tetracene single crystal, collected while rotating the sample by a full turn about the normal to the sample surface (see Fumagalli, Campione, Raimondo, Sassella, Moret, Barba and Arrighetti, pages 682-687). The colour bar shown in the figure represents the diffracted intensity scale in arbitrary units. On the image are superimposed the calculated positions of the diffraction spots from polycrystalline TEN with the (001) planes parallel to the sample surface (green circles), and from polycrystalline RUB with the (200) planes parallel to the sample surface (black circles), along with the Miller indices of the most relevant spots.

Grazing-incidence X-ray diffraction measurements are used to study the structural properties of rubrene crystalline thin films. The use of this technique allows us to determine the crystalline structure of the film and to determine the epitaxial relationship with the substrate, demonstrating also its uniqueness.

The new instrument for ambient-pressure X-ray photoelectron spectroscopy at the Swedish synchrotron radiation facility MAX IV Laboratory is presented. The instrument is based on the use of a retractable and exchangeable high-pressure cell, which implies that ultrahigh-vacuum conditions are retained in the analysis chamber and that dual ambient pressure and ultrahigh-vacuum use is possible.

A two-dimensional imaging system of X-ray absorption fine structure has been developed in the transmission mode and applied to a transient LiMn2O4 cathode during the charging process. The heterogeneous distribution of the Mn oxidation state is demonstrated. The system can be applied to analyze the reaction distribution for the electrode of a Li ion secondary battery.

A sample preparation technique for creating three-dimensional structures for study using X-ray nanotomography (XNT) was developed using focused ion beam/scanning electron microscopy. A Ni/YSZ solid-oxide fuel cell anode sample produced using this technique was then measured by XNT to observe the suitability of produced samples in XNT analysis.
