              about 2 nm thick. Moreover, the originally single-crystalline
              oxide near-surface region became partially polycrystalline after
              exsolution. Such drastic transformations at the surface of the
              oxide are important because the exsolution-induced
              nonstoichiometry and grain boundaries can alter the oxide ion
              transport and oxygen exchange kinetics and, hence, the catalytic
              activity toward water splitting or hydrogen oxidation reactions.
