Photoionization of metastable heliumlike $C^{4+}$($1s\,2s\; ^3S_ 1)$ ions: Precision study of intermediate doubly excited states
In a joint experimental and theoretical endeavor, photoionization of metastable $C^{4+}$($1s\,2s\; ^3S_ 1)$ ions via intermediate levels with hollow, double-K-vacancy configurations $2s2p, 2s3p, 2p3s, 2p3d, 2s4p, 2p4s$, and $2p4d$ has been investigated. High-resolution photon-ion merged-beams measurements were carried out with the resolving power reaching up to 25 800 which is sufficient to separate the leading fine-structure components of the $2s2p^{3}P$ term.

Lattice dynamics of epitaxial strain-free interfaces
We report a systematic lattice dynamics study of the technologically important Fe$_3$Si/GaAs heterostructure for Fe$_3$Si layer thicknesses of 3, 6, 8, and 36 monolayers. The Fe-partial phonon density of states obtained by nuclear inelastic scattering exhibits up to a twofold enhancement of the low-energy phonon states compared to the bulk material for layer thicknesses of 8 monolayers and below.

Correlative microscopy approach for biology using X-ray holography, X-ray scanning diffraction and STED microscopy
We present a correlative microscopy approach for biology based on holographic X-ray imaging, X-ray scanning diffraction, and stimulated emission depletion (STED) microscopy. All modalities are combined into the same synchrotron endstation [...]

Effect of Shear Rate on the Orientation and Relaxation of a Vanillic Acid Based Liquid Crystalline Polymer
Polymers 10(9), 935 () [10.3390/polym10090935] special issue: "Liquid Crystalline Polymers"  GO
In this study, we report on the visco-elastic response during start-up and cessation ofshear of a novel bio-based liquid crystal polymer. The ensuing morphological changes are analyzedat different length scales by in-situ polarized optical microscopy and wide-angle X-ray diffraction.Upon inception of shear, the polydomain texture is initially stretched, at larger strain break upprocesses become increasingly important, and eventually a steady state texture is obtained.

Complete structural and strain analysis of single GaAs/(In,Ga)As/GaAs core–shell–shell nanowires by means of in-plane and out-of-plane X-ray nanodiffraction
Typically, core–shell–shell semiconductor nanowires (NWs) made from III–V materials with low lattice mismatch grow pseudomorphically along the growth axis, i.e. the axial lattice parameters of the core and shell materials are the same [...]

High strength nanocrystalline Cu–Co alloys with high tensile ductility
A supersaturated single-phase Cu–26 at.% Co alloy was produced by high-pressure torsiondeformation, leading to a nanocrystalline microstructure with a grain size smaller than 100 nm.The nonequilibrium solid solution decomposed during subsequent isothermal annealing. In situhigh-energy X-ray diffraction was used to map changes linked to the separating phases, and thedevelopment of a nanoscale Cu–Co composite structure was observed. [...]
