TL;DR: It is demonstrated that femtosecond X-ray laser pulses can be used to probe the structure of liquid water in micrometre-sized droplets that have been evaporatively cooled below TH, and experimental evidence is found for the existence of metastable bulk liquid water down to temperatures of kelvin in the previously largely unexplored no man’s land.

TL;DR: A description of the X-ray Correlation Spectroscopy instrument at the Linac Coherent Light Source is presented and recent highlights illustrate the coherence properties of the source as well as some recent dynamics measurements and future directions.

TL;DR: It is shown that a rapid increase of hydrogen atoms fluctuations at about 220 K, analogous to the one observed in hydrated myoglobin powders, is also observed in a hydrated amino acids mixture with the chemical composition of myoglobin but lacking the polypeptide chain.

TL;DR: In this article, an inline diagnostics device was developed to measure the intrinsic shot-to-shot intensity and position fluctuations of the SASE-based LCLS hard X-ray FEL source.

TL;DR: This study shows that methyl group rotations are unaffected by hydration and confirms that the dynamical transition is suppressed in dry samples, and investigates the role of hydration on the anharmonic contributions.
