TL;DR: The method is pushed into the attosecond regime by focusing on short-lived holes with initial and final states in the same electronic shell, which allows it to show that electron transfer from an adsorbed sulphur atom to a ruthenium surface proceeds in about 320 as.

TL;DR: It is demonstrated that direct laser irradiation is in fact not essential for ultrafast demagnetization, and that electron cascades caused by hot electron currents accomplish it very efficiently.

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.

TL;DR: In this article, a femtosecond x-ray laser pulses are used to probe the carbon monoxide (CO) oxidation reaction on ruthenium (Ru) initiated by an optical laser pulse.

TL;DR: Two distinct adsorption wells—chemisorbed and precursor state separated by an entropy barrier—explain the anomalously high prefactors often observed in desorption of molecules from metals.
