Synthesis of Tri- and Tetranuclear Metal-Sulfur Clusters by the Reaction of a Trisulfido-Bridged Diiron Complex with W(CO)5THF
Authors: Kuge Katsuaki , Tobita Hiromi , Ogino Hiroshi 
Published: September 2002

Abstract
Reaction of trisulfido-bridged diiron complex [CpFe(CO)2]2(µ-S3) with 0.8 equiv of W(CO)5THF produced a trinuclear cluster [CpFe(CO)2]2(µ3-S3)W(CO)5 in which the W(CO)5 moiety was selectively coordinated to one of the α-sulfur atoms of the trisulfido ligand. The reaction with an excess of W(CO)5THF afforded a tetranuclear cluster [CpFe(CO)2]2(µ4-S3)[W(CO)5]2 as a major product in which the W(CO)5 moieties were coordinated to both of the α-sulfur atoms of the trisulfido ligand.

Synthesis and Properties of Diazacrown Ethers Carrying Two Tropone Chromophores
Authors: Yamamoto Emi , Kubo Kanji , Mori Akira 
Published: September 2002

Abstract
N, N′-Bis(tropon-2-yl)diazacrown ethers (2) were found to display unique absorption spectral changes in the presence of guest cations. X-ray crystallographic analysis indicated that 2a·zinc and 2c·calcium thiocyanate complexes consist of an ion pair with zinc tetrathiocyanate anion and 2a·zinc cation, and with calcium hexathiocyanate anion and 2c·H2O·calcium cation, respectively. Complexation gave rise to deconjugation between the tropone ring and the lone pair electrons of the nitrogen atom to cause spectral changes.

The Air Luminescence Count for the Rapid Determination of 222Rn in a Liquid Scintillation Spectrometer
Authors: Morita-Murase Yuko , Murakami Isao , Homma Yoshio 
Published: September 2002

Abstract
A liquid scintillation spectrometer has been applied to the determination of the counting efficiency for the air luminescence produced by standardized 222Rn and its daughters. Based on the counting efficiency, known amounts of 222Rn can be prepared in 3.5 h. Moreover, the 226Ra source from which 222Rn is collected does not necessary have to be a standard one. In contrast, the conventional method for preparing known amounts of 222Rn usually requires a long waiting period (ca. 15–30 days).

Authors: Kodama Yorimitsu , Fujiwara Akihito , Kawamoto Hideki , Ohta Nobuaki , Kitani Akira , Ito Sotaro 
Published: September 2002

Abstract
The cathodic reduction of acetophenone in the presence of a chiral cationic surfactant in aqueous media gave S- or R-1-phenylethanol with 8–12 % ee. The observed enantioselectivity clearly suggests the interaction between the cationic surfactants and the anionic intermediate generated from the one-electron reduction of acetophenone.

Authors: Matsuura Yukihito , Matsukawa Kimihiro , Inoue Hiroshi 
Published: September 2002

Abstract
Polysilane–silica hybrid thin films, in which the polysilane segment is encapsulated within the silica matrix, were prepared by a sol–gel method using copolymers, poly[methylphenylsilane-co-(methacryloxypropyltrimethoxysilane)]. The hybrid thin films were composed of a wide range of polysilane and silica ratios without phase separation. The observed refractive index of the hybrid thin film was changed from 1.61 to 1.49 with a different composition ratio. Their refractive indexes were decreased with degradation of polysilane segments on UV irradiation.

Dielectrophoretic Behavior of Single DNA in Planar and Capillary Quadrupole Microelectrodes
Authors: Tsukahara Satoshi , Yamanaka Katsuyuki , Watarai Hitoshi 
Published: September 2002

Abstract
Dielectrophoresis (DEP) of single DNA (about 40 kbp) labeled with a fluorophore was successfully observed in a planar quadrupole electrode cell whose working area was 65 µm in radius. The DEP behavior depended on frequency (f) of alternating current; positive DEP at lower f and negative DEP at higher f. The combination of the DEP force and a laminar flow in a capillary (82.5 µm in inner radius) with a quadrupole electrode controlled the elution of DNA from the capillary as a function of f.

Published: September 2002

Abstract
Structural features of a stable hairpin DNA with a tetraloop, dAGGC(TTCG)GCCT (CORE), and its six abasic mutants were investigated by the melting behavior of the UV absorption and circular dichroism spectra. The CORE and an abasic mutant at the second position of the loop exhibit considerable thermodynamic stability and have similar structural features suggesting the same folding with an identical base orientation of the two hairpin DNAs except for the second base in the loop.

Published: September 2002

Abstract
The effect of the viscosity of room temperature molten salt (RTMS) electrolyte has been investigated on the performance of dye-sensitized solar cell (DSSC). Both the short circuit photocurrent and conversion efficiency are increased with decreasing the viscosity of RTMS as in the case of conventional electrolytes. The conversion efficiency of 2.1% observed for the cell of EMIm-F·2.3HF is the highest value reported for all the DSSC consisted of RTMS.

Geminal Bond Participation in the Electrocyclic Reactions: Torquoselectivities of Silyl and Trimethylsilyl Derivatives of Cyclobutene, Iminocyclobutene, and Cyclobutenone
Authors: Ikeda Hirotaka , Kato Takayuki , Inagaki Satoshi 
Published: September 2002

Abstract
Analysis of the bond interactions at the transition state of the electrocyclic reaction of cyclobutene shows significant participation of the inward- and outward-rotating σ bonds geminal to the reacting centers. Electron-donating capabilities of the inward-rotating σ bonds are predicted to accelerate the reactions. The prediction of the torquoselectivities is confirmed by calculated preference of the inward rotations of the silyl and trimethylsilyl groups in cyclobutene, iminocyclobutene, and cyclobutenone.

Authors: Itoh Masahiro , Machida Ken-ichi , Hirose Kazuhiro , Adachi Gin-ya 
Published: September 2002

Abstract
Reversible nitrogen absorption and desorption cycle of CeFe7 and Ce2Fe17 was performed by heating in NH3 or N2 for nitrogenation and in H2 for denitrogenation. The nitrogen absorption and desorption rates for CeFe7 were faster than that for Ce2Fe17 owing to the high diffusion rate of nitrogen for CeFe7, resulting that the nitrogen absorption and desorption property of CeFe7 was superior to that of Ce2Fe17.

Abstract
The influence of crystal structure and photocatalytic (PC) reaction on photoluminescence (PL) of several TiO2 powders has been studied at room temperature. The PL intensity of the rutile TiO2 powders increased significantly in proportion to t1/2 by adding ethanol vapor, while those of the anatase TiO2 powders increased slowly. This observation can be explained based on the difference in their PC activities.
