TL;DR: The SwissFEL X-ray Free Electron Laser (XFEL) facility as discussed by the authors started construction at the Paul Scherrer Institute (Villigen, Switzerland) in 2013 and will be ready to accept its first users in 2018 on the Aramis hard Xray branch.

TL;DR: A static and picosecond X-ray absorption study at the Cu K-edge of bis(2,9-dimethyl-1,10-phenanthroline)copper(I) dissolved in acetonitrile and dichloromethane shows an unambiguous assignment of the electronic and geometric structure of the molecule in both its ground and excited (3)MLCT states.

TL;DR: This work uses picosecond X-ray absorption spectroscopy at the Ti K-edge and the Ru L3-edge to address the nature and lifetime of electron traps at room temperature for photoexcited bare and N719-dye-sensitized anatase and amorphous TiO2 nanoparticles and shows that 100 ps after photoexcitation, the electrons are trapped deep in the defect-rich surface shell in the case of anataseTiO2.

TL;DR: In this article, the x-ray absorption spectrum is dominated by sharp transitions which directly reveal the formation of a highly symmetric silicon cage around the vanadium atom, and a nearly identical local electronic structure is found for the dopant atoms in three different cationic transition-metal-doped silicon clusters.

TL;DR: Investigation of zinc oxide nanoparticles using time-resolved X-ray spectroscopy identifies photocatalytically-active hole traps as oxygen vacancies in the lattice, providing insight for future developments of transition metal oxide-based nanodevices.
