Electrodesorption kinetics and molecular interactions in well-ordered thiol adlayers on Au(111)
Article Abstract:
The electrodesorption of square root of 3 * square root of 3 R30 degrees and c(4 * 2) lattices for S and thiols involves nucleation and growth of holes. The S-Au(111) bond for adsorbed thiols in the square root of 3 * square root of 3 R30 degrees adlayer is less ionic than that found for S in the same lattice. The energy difference introduced by this 'extra' ionic character is approximately 19 kJ mol(super -1).

Influence of the nanostructure of palladium mesoparticles on the kinetics of molecular oxygen electroreduction
Article Abstract:
The effect of the nanostructure of electrodeposited palladium mesoparticles on the oxygen electroreduction reaction (oerr) in acid media is studied by electrochemical techniques combined with scanning tunneling microscopy, tapping-mode atomic force microscopy, and scanning electron microscopy. Palladium mesoparticles supported on highly oriented pyrolytic graphite exhibit a remarkable electrocatalytic enhancement.
