ELEMENTARY STEPS OF HYDROGEN EVOLUTION REACTION AT A GOLD ELECTRODE IN AQUEOUS SULFURIC ACID
Authors: Sasaki Takesi , Matsuda Akiya 
Published: July 2006

Abstract
The rate and overvoltage of the constituent elementary steps of the hydrogen evolution reaction at a gold electrode in aqueous sulfuric acid were determined by means of a galvanostatic transient method together with a conventional steady state polarization method. It was concluded that the reaction proceeded through the discharge of hydrated proton which was followed by the recombination of adsorbed hydrogen atoms and the overvoltage of the former step was caused by the free charge on the electrode surface and that of the latter was attributed to the decrease in the electronic work function caused by the adsorbed hydrogen atoms.

ENHANCEMENT OF THE PFEIFFER EFFECT IN TRIS(1,10-PHENANTHROLINE)-ZINC(II)-l-STRYCHNINE SYSTEM
Authors: Yoneda Hayami , Miyoshi Katsuhiko , Suzuki Shingo 
Published: July 2006

Abstract
The Pfeiffer effect in [Zn(phen)3]2+-l-strychnine sulfate system was found to be enhanced by the addition of electrolytes. This phenomenon was interpreted in terms of the weakened electrostatic repulsion between the complex and l-strychnine cations. Hydrophobic bonding between the two cations was suggested from the observation that the Pfeiffer rotation of this system is diminished by the addition of non-electrolytes.

Authors: Tsuhako Mitsutomo , Motooka Itaru , Kobayashi Masamitsu 
Published: July 2006

Abstract
Titanium tetrametaphosphate Ti4(P4O12)3 is readily formed in a nitrogen stream or vacuum.

Abstract
The selectivity coefficient of a liquid ion-exchange membrane, in which an ion-exchange site and counter ions are at almost complete dissociation, was studied by a kind of the bi-ionic membrane potential methods.

Published: July 2006

Abstract
Dehydrobromination of 2-bromobutane and 2,3-dibromobutane proceeded mainly by anti mode over K- and Cs-exchanged silica gel, but syn mode over silica and Li-silica. Upon re-exchange of K and Cs with proton the steric course returned to syn mode. Role of acid-base properties of solid surface and substrate in controlling the steric course was suggested.
