X-ray photon correlation spectroscopy (XPCS) enables the study of sample dynamics
between micrometer and atomic length scales. As a coherent scattering technique, it …

Crystallography has made a notable contribution to our knowledge of structural biology. For
traditional crystallography experiments, the growth of crystals with large size and high …

Abstract The European XFEL (EuXFEL) is a 3.4-km long X-ray source, which produces
femtosecond, ultrabrilliant and spatially coherent X-ray pulses at megahertz (MHz) repetition …

Here, we illustrate what happens inside the catalytic cleft of an enzyme when substrate or
ligand binds on single-millisecond timescales. The initial phase of the enzymatic cycle is …

The emergence of high repetition-rate X-ray free-electron lasers (XFELs) powered by
superconducting accelerator technology enables the measurement of significantly more …

Dynamics and kinetics in soft matter physics, biology, and nanoscience frequently occur on
fast (sub) microsecond but not ultrafast timescales which are difficult to probe …

The world's first superconducting megahertz repetition rate hard X-ray free-electron laser
(XFEL), the European XFEL, began operation in 2017, featuring a unique pulse train …

Featured Application Femtosecond X-ray Experiments on photoexcited chemical systems
deliver a portfolio of new observables including electronic, spin and nuclear dynamics. This …

The Sample Environment and Characterization (SEC) group of the European X-ray Free-
Electron Laser (EuXFEL) develops sample delivery systems for the various scientific …

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 …
