Tracking Electron, Proton, and Solvent Motion in Proton-Coupled Electron Transfer with Ultrafast X-rays
Abdullah Kahraman, Michael Sachs, Soumen Ghosh +24
Proton-coupled electron transfer (PCET) is foundational to catalysis, bioenergetics, and energy conversion, yet capturing and disentangling the coupled motions of electrons, proton…

Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons
Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu +19
We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate latt…
