  • Localized chemical events such as the breakage of a bond between a protein and a ligand may trigger a global protein conformational change. Here, the authors use an X-ray free-electron laser to track the motion of myoglobin in response to photoinduced ligand release, and observe a picosecond proteinquake.

  • Ultrafast nonadiabatic chemical dynamics during molecular photo-transformations remain challenging to describe since electronic/nuclear configurations are coupled. Here the authors use time-resolved X-ray absorption spectroscopy to probe the light-induced spin-state trapping dynamics of [Fe(bpy)3]2+beyond the Born-Oppenheimer approximation.

  • Cyanide-bridged CoFe coordination networks exhibit photomagnetism because of coupled charge-transfer and spin transition. Now, femtosecond X-ray and optical absorption spectroscopies have enabled the electronic and structural dynamics of this light-induced process to be disentangled and show that it is the spin transition on the cobalt atom, occurring within ~50 fs, that induces the Fe-to-Co charge-transfer within ~200 fs.

  • Ultrafast control of materials draws interest. Here, the authors extend X-ray powder diffraction to the femtosecond timescale to follow the photo-induced semiconductor to metal transition in titanium pentaoxide, observing a phase front that moves at the speed of sound and proposing a little explored mechanism.

  • By taking advantage of free-carrier generation in optically transparent media researchers have improved synchronization between optical lasers and free-electron laser pulses. This technique has an optical/X-ray delay with a sub-10 fs r.m.s error.
