TL;DR: The dynamics of the local electronic and geometric structures of WO3 following photoexcitation were studied by femtosecond time-resolved X-ray absorption fine structure (XAFS) spectroscopy and found that the electronic state was the first to change followed by the local structure, which was affected within 200 ps ofphotoexcitation.

TL;DR: The temporal coherence of hard X-ray free-electron laser pulses was characterized by capturing single-shot interferograms with a versatile interferometer composed of six separate optical elements with a mean coherence time of 5.7 fs.

TL;DR: A high-viscosity cartridge-type injector for serial femtosecond crystallography has been developed at SPring-8 Angstrom Compact Free-Electron Laser.

TL;DR: The authors use a two-colour X-ray free-electron laser beam for simultaneous two-wavelength data collection and show that protein structures can be determined with multiple wavelength anomalous dispersion phasing, which is important for difficult-to-phase projects.
