Authors: Kusumi Akihiro , Nakahama Seiichi , Yamaguchi Kazuo 
Published: May 2006

Abstract
Photo-labile phosphatidylcholine (PLPC) was synthesized which contains 2-nitrobenzyl esters at the terminals of both alkyl chains. Photolysis of the esters generates carboxylate ions in the hydrophobic region of the PLPC membrane, leading to instant disintegration of PLPC liposomes as observed by the phase contrast microscopy. Upon UV irradiation, entrapped macromolecules (45-kdalton ovalbumin) were released from PLPC liposomes.

Phosphorescence and Photochemical Properties of Benzophenone Adsorbed on Alkali Cations-Exchanged Zeolite
Authors: Okamoto Seiji , Nishiguchi Hiroyasu , Anpo Masakazu 
Published: May 2006

Abstract
Benzophenone adsorbed on the cation-exchanged ZSM-5 zeolite was found to exist as a protonated form and a hydrogen-bonded form. The exchanged cations had a serious effect on the ratio of those concentrations. Both Benzhydrol and benzpinacol were observed as the major products of the photolysis of the system, their yields strongly depending on the kind of the exchanged cations. The protonated species play a significant role on the photoreactions of benzophenone adsorbed on the zeolite.

Authors: Sayama Kazuhiro , Arakawa Hironori 
Published: May 2006

Abstract
An addition of Na2CO3 played the excellent role for the stoichiometric photodecomposition of liquid water over TiO2 and SrTiO3 loaded with various metals such as Pt, RuO2, and NiOX. The addition of Na2CO3 for TiO2 catalysts was more effective than that for SrTiO3 catalysts. It was suggested that the stoichiometric photodecomposition of water was associated with CO32− ion and neither with Na+ nor pH.

Authors: Takita Yusaku , Sakai Tomoya , Mizuhara Yukako , Ishihara Tatsumi 
Published: May 2006

Abstract
Adsorption of water vapor on crystalline compounds of V-P-O was examined by a TPD method. Water molecules chemisorbed on the V-P-O compounds composed of V(IV) ions such as α- and β-(VO)2P2O7 and VO(PO3)2, were desorbed at 400 °C. However, from compounds consisting of V(V) like V2O5 and VOPO4, only physically adsorbed water molecules were desorbed at 80–200 °C. It can be concluded that the valence of V ions is a key factor for the chemisorption of water vapor on V-P-O compounds.
