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

High-resolution X-ray spectroscopy in the sub-nanosecond to femtosecond time range
requires ultrashort X-ray pulses and a spectral X-ray flux considerably larger than that …

The soft-grainy microstructure of cooked egg yolk is the result of a series of out-of-
equilibrium processes of its protein-lipid contents; however, it is unclear how egg yolk …

X-ray free-electron lasers (XFELs) with megahertz repetition rate can provide novel insights
into structural dynamics of biological macromolecule solutions. However, very high dose …

Understanding and interpreting dynamics of functional materials in situ is a grand challenge
in physics and materials science due to the difficulty of experimentally probing materials at …

We present an x-ray regenerative amplifier free-electron laser design capable of producing
fully coherent hard x-ray pulses across a broad tuning range at a high steady state repetition …

The heterogeneous nature, local presence, and dynamic evolution of defects typically
govern the ionic and electronic properties of a wide variety of functional materials. While the …

Stimuli-responsive polymers are an important class of materials with many applications in
nanotechnology and drug delivery. The most prominent one is poly-N-isopropylacrylamide …

The European X-ray Free Electron Laser (European XFEL) is a cutting-edge user facility that
generates per second up to 27,000 ultra-short, spatially coherent X-ray pulses within an …

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 …
