The Front Cover shows ammonia molecules adsorbed on an atomically flat platinum surface. An ultra‐short laser pulse hits the surface and heats up the metal electron rapidly to several thousand Kelvin within a few 100fs. This high electronic temperature causes a fraction of the ammonia molecules to desorb with hyperthermal velocity from the surface.
