TL;DR: In this article, the authors dealt with TTF/FLASH in the XFEL context, general layout of the X-FEL facility, the X FEL accelerator, undulators for SAES and spontaneous emission, infrastructure and auxiliary systems, commissioning and operation, project management and organization, cost and time schedule.

TL;DR: Direct observation by x-ray diffraction of a photoinduced paraelectric-to-ferroelectric structural phase transition using monochromatic 100-picosecond synchrotron pulses in tetrathiafulvalene-p-chloranil indicates structural changes at the molecular level.

TL;DR: It is shown that, to first order in time, the dynamics are inertial, and constraints on the shape and curvature of the transition-state potential energy surface are placed, pointing toward analogies between this nonequilibrium phase transition and the short-time dynamics intrinsic to equilibrium liquids.

TL;DR: In this article, the Max Planck Advanced Study Group (ASG) within the Center for Free Electron Laser Science (CFEL) has designed the CFEL-ASG MultiPurpose (CAMP) chamber.

TL;DR: It is shown that the photo-induced removal of CO generates the 16-electron Fe(CO)4 species, a homogeneous catalyst with an electron deficiency at the Fe centre, in a hitherto unreported excited singlet state that either converts to the triplet ground state or combines with a CO or solvent molecule to regenerate a penta-coordinated Fe species on a sub-picosecond timescale.
