TL;DR: T tunable femtosecond soft x-ray pulses from an x-rays free electron laser are used to reveal the dynamics of the valence hole created by strong-field ionization and to track the primary proton transfer reaction giving rise to the formation of OH.

TL;DR: In this article, the photoinduced lattice changes in perovskite-based optoelectronic devices are due to a specific polaronic distortion, associated with the activation of a longitudinal optical phonon mode at 18 meV by electron-phonon coupling.

TL;DR: This work demonstrates that the photoinduced lattice changes in the CsPbBr3 perovskite-based optoelectronic system are due to a specific polaronic distortion, associated with the activation of a longitudinal optical phonon mode at 18 meV by electron–phonon coupling, and quantifies the associated structural changes with atomic-level precision.

TL;DR: A continuous SrF radical beam for the loading of helium buffer gas cooling and the dependence of the flux on oven temperature suggests that even higher flux is possible if a higher temperature in the oven is achieved.

TL;DR: Time-resolved X-ray absorption spectroscopy in the ns-μs time scale is used to track the light induced two electron transfer processes in a multi-component photocatalytic system, consisting of [Ru(bpy)3]2+/ a diiron(iii,iii) model/triethylamine.
