CAMP@FLASH: an end-station for imaging, electron- and ion-spectroscopy, and pump–probe experiments at the FLASH free-electron laser
The non-monochromatic beamline BL1 at the FLASH free-electron laser facility at DESY was upgraded with new transport and focusing optics, and a new permanent end-station, CAMP, was installed. This multi-purpose instrument is optimized for electron- and ion-spectroscopy, imaging and pump–probe experiments at free-electron lasers [...]

Elastic Softening of $\mathrm{(Mg_{0.8}Fe_{0.2})O}$ Ferropericlase Across the Iron Spin Crossover Measured at Seismic Frequencies
Geophysical research letters 45(14), 6862 - 6868 () [10.1029/2018GL077982]  GO
We experimentally determined the bulk modulus of (Mg$_{0.8}$Fe$_{0.2}$)O ferropericlase across theiron spin transition and in the low-spin phase by employing a new experimental approach. In ourmeasurements, we simulate the propagation of a compressional seismic wave (P wave) through our sampleby employing a piezo-driven dynamic diamond anvil cell that allows to oscillate pressure at seismicfrequencies.

Next-generation materials for future synchrotron and free-electron laser sources
Energy quarterly 42(6), 418 - 423 () [10.1557/mrs.2017.118]  GO
The development of new materials and improvements of existing ones are at the root of the spectacular recent developments of new technologies for synchrotron storage rings and free-electron laser sources. This holds true for all relevant application areas, from electron guns to undulators, x-ray optics, and detectors. [...]

Azobenzene-cholesterol as a photoactivator in biomimetic membranes: 2. membrane structure
Biophysical Society Annual Meeting 2017, New OrleansNew Orleans, United States, 11 Feb 2017 - 15 Feb 20172017-02-112017-02-15  GO
Properties of biomembranes are modified in presence of additives such as cholesterol (chol) or proteins. Azobenzene-cholesterol (azo chol) is a photoactive variety of chol since its azo-headgroup exhibits a reversible change of the conformation upon illumination (365nm: trans to cis; 455nm: cis to trans).

X-ray focusing with efficient high-NA multilayer Laue lenses
Light 7(3), 17162 () [10.1038/lsa.2017.162]  GO
Multilayer Laue lenses are volume diffraction elements for the efficient focusing of X-rays. With a new manufacturing technique that we introduced, it is possible to fabricate lenses of sufficiently high numerical aperture (NA) to achieve focal spot sizes below 10 nm. [...]

Reversibility and hysteresis of the sharp yielding transition of a colloidal glass under oscillatory shear
The mechanical response of glasses remains challenging to understand. Recent results indicate that the oscillatory rheology of soft glasses is accompanied by a sharp non-equilibrium transition in the microscopic dynamics. [...]
