The crystal structure of the recently reported La3TiBi5 phase is refined for the first time from single-crystal X-ray diffraction data. Structural analysis and first-principles calculations show the presence of undistorted linear Bi chains with hypervalent bonding.

The development of a novel experimental capability of nuclear resonant inelastic X-ray scattering at high pressure and low temperature is presented. The new capability is demonstrated by studying the Fe-specific phonon density of states and magnetism in Eu57Fe2As2.

A new type of artifact is described, which was observed in a wide variety of inelastic neutron scattering spectra and which could easily be mistaken for a signature of real excitations.

The new ternary arsenide Rb3Cu3As2 is isotypic with K3Cu3P2. The structure features layers of interlinked CuAs2 linear moieties.

A study of the ternary Rh–Mn–Bi phase diagram revealed the existence of two new ternary bismuthides, viz. hexarhodium pentamanganese octadecabismuthide (Rh6Mn5Bi18) and rhodium manganese tribismuthide (RhMnBi3). Their crystal structures represent new structure types.

Concepts and technical realization of the soft-X-ray ARPES facility at the Swiss Light Source are described. Its performance is illustrated by a few scientific applications ranging from three-dimensional materials to buried interfaces and impurities.

A sample preparation technique has been developed to enable the safe measurement of radioactive powders on the high-resolution powder diffraction beamline, ID31, at the European Synchrotron Radiation Facility.

A review of the LDA+DMFT method and examples of its applications to real materials with strong electronic correlations, including SrVO3, V2O3, LiV2O4, iron pnictide materials, metallic cerium, NiO and MnO.

Synchrotron X-ray diffraction measurements on BaFe1.9Ru0.1As2 single crystals were performed at different temperatures across the spin-density wave/structural transition. A clear anomaly in the c-axis, As—Fe—As bond angle and Fe—As bond lengths has been observed close to the structural transition. These anomalies in structural parameters are analysed using ab initio electronic structure calculations
