Microsecond hydrodynamic interactions in dense colloidal dispersions probed at the European XFEL

IUCrJ, 2021
Many soft-matter systems are composed of macromolecules or nanoparticles suspended in water. The characteristic times at intrinsic length scales of a few nanometres fall therefore in the microsecond and sub-microsecond time regimes.

Data driven drift correction for complex optical systems. [PDF]

J Synchrotron Radiat
Time varying Bayesian optimization as a data driven approach for robust drift correction is outlined, and its application for a split and delay x‐ray optical system is illustrated.To exploit the thousand‐fold increase in spectral brightness of modern light sources, increasingly intricate experiments are being conducted that demand extremely precise ...

Speckle contrast of interfering fluorescence X-rays

Journal of Synchrotron Radiation, 2023
With the development of X-ray free-electron lasers (XFELs), producing pulses of femtosecond durations comparable with the coherence times of X-ray fluorescence, it has become possible to observe intensity–intensity correlations due to the interference of

A Human XPC Protein Interactome—A Resource [PDF]

International Journal of Molecular Sciences, 2013
Global genome nucleotide excision repair (GG-NER) is responsible for identifying and removing bulky adducts from non-transcribed DNA that result from damaging agents such as UV radiation and cisplatin. Xeroderma pigmentosum complementation group C (XPC) is one of the essential damage recognition proteins of the GG-NER pathway and its dysfunction ...

The PERCIVAL detector: first user experiments

Journal of Synchrotron Radiation, 2023
The PERCIVAL detector is a CMOS imager designed for the soft X-ray regime at photon sources. Although still in its final development phase, it has recently seen its first user experiments: ptychography at a free-electron laser, holographic imaging at a ...

Coupling x-ray photon correlation spectroscopy and dynamic coherent x-ray diffraction imaging: Particle motion analysis from nano-to-micrometer scale

Physical Review Research, 2023
Two well-known measurement methods use coherent x rays: x-ray photon correlation spectroscopy (XPCS) and coherent x-ray diffraction imaging (CXDI). We propose and demonstrate an approach to analyze particle motion in heterogeneous solutions over a wide ...
