N2 - The reversible dynamic behavior in catalyst systems and oscillations of structure and morphology were discussed. It was found that exposure of vanadium oxide nanoparticles on a Pd surface to reducing conditions lead to spreading of the oxide over the metal until a reduced oxide phase covered the entire surface. The physical origin of wetting-dewetting process was revealed at atomic level by in situ variable temperature scanning tunneling microscopy.
