Photothermal Dynamics at the Surface of Copper Phthalocyanine Solid Revealed by Time-resolved Regular Reflection Spectroscopy
Authors: Fukumura Hiroshi , Yoneda Yoshikazu , Takahashi Hitoki , Masuhara Hiroshi 
Published: March 2006

Abstract
Flat surfaces of compressed pellets made of copper phthalocyanine powders were excited by nanosecond laser pulses and their time-resolved extinction coefficients were obtained by using regular reflection spectroscopy independent of Kramers-Kronig transformation. The results showed transient depletion at the peaks of the ground state absorption spectra, which is due to a change in thermal population in vibrational states. The decay of the transient depletion was well described with the temperature dependency of extinction coefficient based on Sulzer-Wieland approximation and one-dimensional thermal diffusion towards the deep parts of the pellet samples.
Observation of Intermolecular Charge-Transfer Spectra for Propyl Viologen Dihalides in a Series of Polyether Media
Authors: Satoh Hideharu , Tokuda Koichi , Ohsaka Takeo 
Published: March 2006

Abstract
1,1-Dipropyl-4,4-bipyridinium diiodide(PV2+·2I−) in a series of polyethers (PEOs, HO-(-CH2CH2O-)n-H, n = 1∼14)1 gave an intermolecular charge-transfer spectrum, which shifted to longer wavelength with larger absorbance in less polar medium, in the visible region. An increase in temperature resulted in an increase in absorbance as a result of an ion-dipole interaction between PV2+ cation and polyether solvent.

Authors: Tang Heqing , Kitani Akira , Yamashita Tomoyuki , Ota Yoshifumi , Shiotani Masaru 
Published: March 2006

Abstract
Polyaniline was possibly doped with cresol-sulfonic acid, though it failed to electrodeposit the polymer from solutions of aniline in cresol-sulfonic acid. The presence of cresol-sulfonate anions changed the redox peaks of the polymer in thier positions and heights. Catalytic oxidation of cresol-sulfonic acid was observed on polyaniline-filmed electrodes at potentials of a limited interval.

In situ Optical Second Harmonic Generation Study of Electrochemical Oxidation of Formaldehyde on a Polycrystalline Platinum Electrode
Authors: Yagi Ichizo , Nakabayashi Seiichiro , Uosaki Kohei 
Published: March 2006

Abstract
In situ optical second harmonic generation(SHG) technique was employed to investigate the electrochemical oxidation of formaldehyde on a polycrystalline Pt electrode. At 532 nm excitation, the SH signal generated at a Pt surface seems to be enhanced by the existence of adsorbed CO and can be related to the surface coverage of CO(a) which cannot be determined by the electrochemical methods. Thus, the potential dependence of the SH signal provides useful information to understand the mechanism of this reaction.

Stereoseletive Reduction of β-Hydroxy Ketones to 1,3-Diols with the Aid of a Terphenylboronic Acid
Authors: Yamashita Hiroshi , Narasaka Koichi 
Published: March 2006

Abstract
1-Hydroxy-6,8-diphenyl-1,2,3,4-tetrahydro-2-oxa-1-boranaphthalene (terphenylboronic acid 1), is employed for stereoselective reduction of acyclic and cyclic β-hydroxy ketones. The terphenylboronic acid 1 and acyclic β-hydroxy ketones 2 are converted to the corresponding boronates by azeotropic removal of water. The resulting boronates are treated in situ with reducing reagents to give syn 1,3-diols 3 almost exclusively. Anti α-substituted β-hydroxy ketones 8 are also reduced to give anti, anti 1,3-diol 9 stereoselectively. Furthermore, the reduction of 3-hydroxy-1-cyclopentanone gives a cis diol 11 in high selectivity.

Published: March 2006

Abstract
Oxidative capture and recovery of SO2 in form of H2SO4 was examined over pitch based active carbon fibers (P-ACF-OG-15A and -20-A).

Authors: Miyao Toshihiro , Shishikura Isao , Matsuoka Masakuni , Nagai Masatoshi 
Published: March 2006

Abstract
The alumina-supported Mo carbide catalyst was synthesized using a chemical vapor deposition (CVD) technique. The CVD carbide exhibited an extremely high activity for the reduction of CO2, compared to the alumina-impregnated carbide. The XPS and XRD analyses showed the formation of Mo carbide on the alumina. The increase in the BET surface area of the CVD carbide with increasing Mo loading suggested that very fine particles of Mo carbide were formed on the alumina.
Oscillatory Behavior in Electrochemical Deposition Reaction of Polycrystalline Silicon Thin Films through Reduction of Silicon Tetrachloride in a Molten Salt Electrolyte
Authors: Matsuda Toshihiko , Nakamura Shinsuke , Ide Ken-ichiro , Nyudo Kazuiku , Yae Shinji , Nakato Yoshihiro 
Published: March 2006

Abstract
A new electrochemical oscillation is found for reduction reaction of silicon tetrachloride on a partially immersed single crystal n-Si electrode in a lithium chloride-potassium chloride eutectic melt electrolyte. The reduction of SiCl4, which is almost insoluble in the electrolyte, occurs mainly near the upper edge of an electrolyte meniscus on the electrode, and it is discussed that the oscillation is caused by a change in the height of the meniscus due to a change in the chemical structure (and hence the interfacial tension) of the electrode surface with progress of the silicon deposition reaction.

Published: March 2006

Abstract
Kinetic behavior of atropisomerization of tetraphenylporphyrin derivative containing equilibrium processes of dimer formation were analyzed directly by a non-linear least square optimization method which uses numerical integration of kinetic differential equations. Analyses clearly indicate a kinetic model determined with one rate and two equilibrium constants as the most plausible mechanism.

Published: March 2006

Abstract
An 18-peptide, T22, has been shown to have a strong anti-human immunodeficiency virus (HIV) activity comparable to that of 3′-azido-3′-deoxy-thymidine (AZT). Several shortened analogs of T22 were designed, synthesized and evaluated of their anti-HIV activities. A 14-peptide analog with one disulfide bond, TW70 (des-Cys8,13, Tyr9,12-[d-Lys10, Pro11]-T22), showed comparable activity to that of T22, indicating that the molecular size of T22 could be reduced without loss of the activity.

Abstract
The purpose of this work is to clarify the relationship between some of the properties of MOS (metal, oxide, silicon) capacitors passivated by Ba(PO3)2-Al(PO3)3-B2O3 glasses and the hydroxyl contents of the glasses. When substitution of Al(PO3)3 for Ba(PO3)2 progressively decreased the OH− absorption intensity, the C-V (capacitance-voltage) curve shift, ΔVG in the MOS capacitors decreased.
Role of the Methoxy Substituents on the Photochromic Indolyfulgides. Absorption Maximum vs. Molar Absorption Coefficient of the Colored Form
Authors: Yokoyama Yasushi , Sagisaka Toshiya , Mizuno Yukitami , Yokoyama Yayoi 
Published: March 2006

Abstract
While the introduction of a methoxy group to C-5 of the indole ring of the indolylfulgide caused a large bathochromic shift of the absorption maximum of its colored form, introduction of a methoxy group to C-6 resulted in enlargement of the molar absorption coefficient of the colored form. The 5,6-dimethoxy-substituted indolylfulgide has both properties.

Transfer Kinetics of Amphiphilic Porphyrin between Organic Phase and Water Phase
Authors: Mizutani Tadashi , Tobisawa Akihiko , Ogoshi Hisanobu 
Published: March 2006

Abstract
Amphiphilic prophyrins having a poly(ethylene oxide) chain were prepared. The transfer rates of the amphiphilic porphyrin from benzene to water were biphasic and were accelerated by lowering temperature or by the addition of SDS. Kinetic data suggest that (1) conformational changes of the amphiphilic prophyrin to a polar form give rise to the faster rate at low temperature, and (2) adsorption to the interface leads to the biphasic kinetics.
