  • The findings that the spatial distribution of an optical field with vortex phase profile can be imprinted coherently onto a propagating electron wave reveal new aspects of light–matter interactions and will help develop future single-photon electron spectroscopy.

  • Metal clusters are known to catalyze hydrogen evolution from water, but reaction mechanisms and reactivities are still not fully understood. Here, mass spectrometry of cationic vanadium clusters reacting with water vapor shows significant hydrogen evolution reactions for V3+, V5+ and V9+ that point to a hydrogen release mechanism from the transition metal cluster cations.
