Authors: Miyasaka Tsutomu , Koyama Koichi 
Published: May 2006

Abstract
Langmuir–Blodgett films of the halobacterial purple membrane were formed on SnO2 conductive electrodes. Generation and the behavior of bacteriorhodopsin induced photocurrents at the interface of electrode and aqueous electrolyte were investigated under controlled potentials in an electrochemical cell. Efficient and rectified photocurrents were obtained, demonstrating significant dependence on the electrode potential and pH of the electrolyte.

Authors: Maekawa Hirofumi , Nakano Kazuharu , Hirashima Tsuneaki , Nishiguchi Ikuzo 
Published: May 2006

Abstract
Electrolysis of enol esters of cyclic ketones possessing an alkyl group at the α-position using graphite carbon electrodes (EGM62 or EG10 : Nippon Carbon Co. Ltd.) brought about selective dimerization at the β-position of the ketones to give the corresponding 1,6-diketones in good to moderate yields. It was found that initial anodic formation of α,β-unsaturated ketones was successively followed by cathodic hydrodimerization (paired electrolysis) in an undivided cell.

Water Vapor Influence on Carbon Dioxide Detection of the Sensor Based on Lithium Conducting Solid Electrolyte
Authors: Imanaka Nobuhito , Kawasato Takeshi , Adachi Gin-ya 
Published: May 2006

Abstract
The influence of the water vapor on the CO2 selectivity of the sensor based on a lithium ionic conductor has been investigated. In a CO2 gas concentration higher than 1000 ppm, the sensor was able to detect the CO2 content continuously even when the vapor coexisted up to 222.8 g/m3. In a CO2 concentration lower than 1000 ppm, EMF deviated lower with the increase of the water vapor content. This might be attributed to the lithium hydroxide formation on the solid electrolyte surface by the chemical reaction between the Li2CO3+Li2O electrode and water vapor in the atmosphere.
