Authors: Inumaru Kei , Okuhara Toshio , Misono Makoto 
Published: May 2006

Abstract
(VO)2P2O7 consisting of thin planar crystallites, which was selective for the butane oxidation, was first deactivated by the deposition of SiO2 thin layer, and then fractured to create new side faces like (001) and (021). The side faces were non-selective for the reaction, indicating that (100) face, on which V4+(=O)–O–V4+ sites are located, is selective.

Authors: Funaki Hiroshi , Aramaki Kunitsugu , Nishihara Hiroshi 
Published: May 2006

Abstract
Electrochemical and electrical properties of soluble poly(n-hexylphenylene) bound to Mo(CO)3 were investigated by cyclic voltammetry, spectro-electrochemistry and four-electrode voltammetry. Oxidation of the Mo complex polymer occurs at E0′ = 0.51 V vs. Ag/Ag+, which is less positive than that of free poly(n-hexylphenylene) by ca. 0.3 V. At this potential, conductivity of the Mo complex polymer increases. The band gap of the polyphenylene does not change significantly by coordinating to Mo.
