In situ surface X-ray scattering (SXS) measurements were carried out to study the structure of a Ag layer on a Au(111) electrode formed by underpotential deposition (upd) in sulfuric acid solution.

8. Electrochemical oxidative adsorption and reductive desorption of a self-assembled monolayer of decanethiol on the Au(111) surface in KOH+ethanol solution - Sumi, Takayoshi; Wano, Hiromi; Uosaki, Kohei
The adsorption increased with the holding time at +0.1 V, which was much more positive than the anodic peak potential, and reached the saturated amount in ca.

9. Electron and ion transport through multilayers of Au nanoclusters covered by self-assembled monolayers - Song, Wenbo; Okamura, Masayuki; Kondo, Toshihiro; Uosaki, Kohei
Two types of gold nanoclusters (GNCs), one covered by self-assembled monolayers of mercaptoundecanoic acid (MUA), hexanethiol (C6SH), and ferrocenylhexanethiol (FcC6SH), MHF-GNC, and the other with MUA and C6SH, MH-GNC, were used for the construction of ten GNC layers of two different sequences on an MUA modified Au(1 1 1) surface based on the carboxylate/polycation (poly(allylamine hydrochloride), PAH)/carboxylate electrostatic interaction.
