✦ Synopsis

The interaction of atomic and molecular hydrogen with surfaces of Al and Na has been investigated with electron energy loss spectroscopy, thermal desorption, and work function measurements. After exposing these surfaces at Tb 100 K to Hz, no evidence was found for adsorption of either molecular or atomic hydrogen; however, after exposure to atomic hydrogen, adsorbed H was observed. The adsorption sites, work function changes and desorption behavior are discussed in relation to existing theories using jellium and modified jellium substrates.

The specific adsorption of anions (HSO(4)(-), H(2)PO(4)(-), and Cl(-)) was studied at Fe(2)O(3), ZnO, and CuO surfaces by the radiotracer technique in strongly acidic medium (1 M HClO(4)). A significant specific adsorption of HSO(4)(-) and H(2)PO(4)(-) ions was found in all cases studied while no me
