Ion-sieving of electrosynthesized polypyrrole films

Hiroaki Shinohara、Masuo Aizawa、Hideki Shirakawa1986-01-01Journal of the Chemical Society Chemical Communications

A polypyrrole film which was electrochemically synthesized in the presence of NaCl showed permeability in electrochemical doping to Cl– and anions of comparable diameter and prevented anions of larger diameter such as EtSO3– from penetrating the matrix.

Ag3O4, the First Silver(II,III) Oxide

Burkhard Standke、Martin Jansen1986-01-01Angewandte Chemie International Edition in English

The silver oxide Ag 3 O 4 contains crystallographically differentiable di‐ and trivalent silver ions, each in square‐planar oxygen environment. From the bond lengths it is concluded that extensive charge equalization takes place between Ag 2+ and Ag 3+ , Ag 3 O 4 is obtained by anodic oxidation of silver salt solution…

Plipastatins: New inhibitors of phospholipase A2, produced by Bacillus cereus BMG302-fF67. I. Taxonomy, production, isolation and preliminary characterization.

HAMAO UMEZAWA、TAKAAKI AOYAGI、Takaaki Nishikiori 等 7 位作者1986-01-01The Journal of Antibiotics

Plipastatins have been isolated as part of a program designed to find inhibitors of porcine pancreatic phospholipase A2. They were purified from fermentation broth of Bacillus cereus BMG302-fF67 and finally separated into four fractions by reverse phase HPLC. The respective fractions were designated as plipastatins A1…

The calculation of inrush current in three-phase transformers

R. Yacamini、A. Abu-Nasser1986-01-01IEE Proceedings B Electric Power Applications

The inrush current associated with energising power transformers can cause interference and damage to other system components. The paper sets out to describe an accurate analytical method which can be used to find the inrush current in any 3-phase transformer in common use. The method is an extension of one previously…

Catalysis of Diels–Alder reactions by zeolites

Ralph M. Dessau1986-01-01Journal of the Chemical Society Chemical Communications

The Diels–Alder Cyclodimerization of buta-1,3-diene to 4-vinylcyclohexene was found to be catalysed by non-acidic zeolites, especially large-pore zeolites such as Na-ZSM-20, Na-β, and Na-Y, and also by carbon molecular sieves.

Polyethylene‐polycarbonate blends: Interface modification, phase morphology and measurement of orientation development during cast film and tubular extrusion by infrared dichroism

SHIGERU ENDO、Kyonsuku Min、James L. White 等 4 位作者1986-01-01Polymer Engineering and Science

Abstract The phase morphology and polymer chain orientation in polyethylene‐polycarbonte blends is investigated. A blend with a dispersed polyethylene phase was found to exhibit phase growth under quiescent conditions. Addition of a styrene‐(ethylene/butene) block copolymer controls the phase morphology and prevents p…

Application of a Slip Dissolution-Repassivation Model for Stress Corrosion Cracking of AISI 304 Stainless Steel in a Boiling 42% MgCl2 Solution

Tsuneyoshi Nakayama、Michinori Takano1986-01-01CORROSION

Dissolution-repassivation behavior of AISI 304 stainless steel (SS) in 42% MgCl2 at 143 C was investigated using a straining electrode technique at different potentials. Dissolution current, i(t), was expressed as i(t) = Jo•exp(−βt), where Jo is the initial dissolution current density (CD) of slip steps, β is the deca…

Photoredox chemistry of Keggin dodecatungstoborate [BW12O40]5? and role of heterogeneous catalysis in hydrogen formation

Toshihiro Yamase、Reiko Watanabe1986-01-01Journal of the Chemical Society Dalton Transactions

Photoexcitation of the oxygen-to-tungsten charge-transfer band of [BW12O40]5– in the presence of CH3OH leads to the formation of [BW12O40]6–, H2, and formaldehyde at 2.0 < pH < 9.4, with a resultant liberation of protons from CH3OH. Low values (1.6–1.8) of the kinetic isotope effect imply that the electron transfer fr…

An Extended Range Liquid Extrusion Method for Determining Pore Size Distributions

Bernard Miller、Ilya Tyomkin1986-01-01Textile Research Journal

A liquid extrusion method for determining pore volume distributions has been developed that is especially useful for, but not restricted to, characterizing fibrous materials. It involves gravimetric monitoring of liquid that drains from an initially saturated sample as incremental increases in pressure gradient are ap…

Polarons and Bipolarons in Doped Polythiophenes

G. Harbeke、D. Baeriswyl、H. Kieß 等 4 位作者1986-01-01Physica Scripta

The optical transitions induced by doping poly(3-methylthiophene) or polythiophene with BF 4 − or ClO 4 − have been investigated by in-situ spectroscopy in an opto-electrochemical cell. From the number of doping-induced bands and concentration dependence we found evidence that polarons are the primary electronic excit…

The Dynamics of the Glass Transition

S. F. Edwards、Th. Vilgis1986-01-01Physica Scripta

Accepting the widely held view that all glass transitions have the same features, a particularly simple model of a liquid of long rod molecules is studied. It is shown that the equations of motion of such a system are remarkably simple and permit simple intuitive pictures of the glass transition to be translated into…

The effect of molecular biaxiality on the bulk properties of some nematic liquid crystals

John D. Bunning、D. A. Crellin、T. E. Faber1986-01-01Liquid Crystals

The nematic substance 5CB is known from N.M.R. studies to be slightly biaxial, not in the sense that any bulk property measured in a direction at right angles to the director is liable to vary with rotation about the director, but in the sense that there are biaxial terms in the ordering matrix that describes the alig…

Biforked mesogens : a new type of thermotropic liquid crystals

Nguyễn Hữu Tình、C. Destrade、A. M. Levelut 等 4 位作者1986-01-01Journal de physique

Some biforked mesogens belonging to five series were prepared and studied. They exhibit an interesting polymorphism in which both columnar and lamellar mesomorphic orders coexist at different temperatures. The short chains lead to the classical nematic phase and/or the smectic C phase. The long ones give evidence of a…
