Intramolecular Charge Interaction in the Radical Cations and Dications of Conjugated Tetrathiafulvalene Dimers
Authors: Iyoda Masahiko , Hasegawa Masashi , Takano Jun-ichi , Hara Kenji , Kuwatani Yoshiyuki 
Published: September 2002

Abstract
Dimeric TTFs have been synthesized by using palladium-catalyzed reactions. Although TTFs are very sensitive under oxidation conditions, the palladium-catalyzed reactions can be successfully employed for the oxidative coupling of TTF derivatives. The chemical oxidation of dimeric TTFs produced cation-radicals, dications, and tetracations selectively. Electronic spectra of the cation-radicals clearly indicate the magnitude of the intramolecular interaction between two TTF moieties.

A Simple, Effective, and Selective Synthesis Route for Difunctional 30-Membered Macrocyclic Ester and Linear Oligoester Derived from Benzoxazine Dimers
Authors: Laobuthee Apirat , Chirachanchai Suwabun 
Published: September 2002

Abstract
A series of benzoxazine dimer based difunctional 30-membered macrocyclic and linear oligomer esters are selectively obtained in simple and mild condition. The unique intramolecular hydrogen bond of the dimer is a key factor to proceed the “self-selective reaction” in esterification between terephthaloyl chloride and benzoxazine dimers. This is a so-called “simple, effective, and selective synthesis route” since we can obtain a well-defined structure product in a high yield without using expensive catalysts for multistep reactions in specific conditions.

Authors: Wang Hongzhi , Chen Yunfa , Nakamura Hiroyuki , Yao Ken , Nishimura Satoshi , Abe Eiichi 
Published: September 2002

Abstract
A modified Stober method has been used to provide a silica coating on ZnO particles while maintaining good dispersion of the ZnO particles. The results showed that the utilization of a previous hydrolysis process could reduce aggregation between core particles in the starting solution and that few little agglomerates appeared during the coating process. Silica coated powders prepared in this study reduced the photocatalysis reaction of ZnO particles.

A new autocatalytic mechanism based on a rough electrode surface is proposed to explain the phenomena systematically.

Authors: Nakashima Naotoshi , Tomonari Yasuhiko , Murakami Hiroto 
Published: September 2002

Abstract
In this communication, we describe the finding that sonication of solid single-walled carbon nanotubes (p-SWNT) in an aqueous solution of a pyrene-carrying ammonium ion 1 gave a transparent dispersion/solution of the nanotubes, which was characterized by transmission electron microscopy, UV-vis absorption, fluorescence and 1H NMR spectroscopies. We showed evidence for the interaction of the nanotube sidewall and the pyrene moiety in the aqueous dispersion/solution.
An Unusual, DDQ-Promoted Oxidative Rearrangement of 9,9-Disubstituted 1,4,5,8-Tetrahydro-4a,8a-methanonaphthalenes
Authors: Barasz Jonah A , Ghaffari Ali H , Otte Douglas A , Thamattoor Dasan M

Abstract
The action of excess DDQ on 1,4,5,8-tetrahydro-4a,8a-methanonaphthalenes bearing a methyl group and one other substituent (cyclopropyl, methyl, phenyl) at the 9 position resulted in a peculiar oxidative rearrangement to 1-vinylnaphthalene derivatives. Two closely related mechanisms, both of which involve a 1,5-sigmatropic shift of the one-carbon bridge (Berson-Willcott rearrangement), are considered for this novel process.

Authors: Lee Yun Sung , Sun Yang Kook , Kobayakawa Koichi , Sato Yuichi 
Published: September 2002

Abstract
LiFe0.97Co0.03O1.95Cl0.05 has been synthesized at 150 °C using the solid-state method. A Li/LiFeO2 cell as reported previously exhibited a large capacity decline until 15 cycles. To obtain a good cycleability of LiFeO2, Co and Cl ions substituted some Fe and O atoms of the LiFeO2 structure. LiFe0.97Co0.03O1.95Cl0.05 showed small lattice parameters compared with those of LiFeO2. This material showed a good cycleability with fairly a high discharge capacity of over 134 mAh/g at high current density.

Electrocatalytic Reduction of Sulfur Dioxide by Iron Phthalocyanine Monolayer in Acidic Conditions
Authors: Yu Cheol Su , Choi Hyukjae , Kim Sunghyun 
Published: September 2002

Abstract
The iron phthalocyanine (FePc) monolayer adsorbed on a graphite surface showed a remarkable activity for the SO2 reduction in aqueous conditions. The highest activity was observed at strongly acidic solutions and decreased with a pH increase due to the H+ limitation of reduction. Only SO2 and HSO3- are reducible forms. The reduction mechanisms at strongly and moderately acidic conditions were suggested. The SO2 reduction current was independent of the surface coverage and the ppb level detection was possible with amperometry.

Sorption of Eu(III) on Kaolinite in the Presence of Humic Acid: Effects of Ionic Strength
Authors: Sakuragi Tomofumi , Sato Seichi , Kozaki Tamotsu 
Published: September 2002

Abstract
The effects of ionic strength on the sorption of Eu(III) on kaolinite in the presence of humic acid (HA) were examined using a batch method. Eu(III) sorption increased with increased ionic strengths in the pH range of 6 to 10, but was insensitive to ionic strength in the pH range below 5. Adsorption of HA onto kaolinite also increased in the pH range of 6 to 10, indicating that the increase in adsorption of Eu(III)-humate complexes is a predominant process for the increase in Eu(III) sorption.

Authors: Kohtani Shigeru , Makino Shigeki , Kudo Akihiko , Tokumura Kunihiro , Ishigaki Yasuhito , Matsunaga Tsukasa , Nikaido Osamu , Hayakawa Kazuichi , Nakagaki Ryoichi 
Published: September 2002

Abstract
A toxic endocrine disruptor, 4-n-nonylphenol, was degraded using a well-known TiO2 and a visible-light-driven BiVO4 photocatalyst under irradiation from a solar simulator. The degradation rates for both BiVO4 and TiO2 are comparable in air-saturated solution though surface area of BiVO4 is much smaller than that of TiO2. This fact indicates that BiVO4 has a great ability to degrade alkylphenols in wastewater under solar light.
