Abstract Poly(ethylene terephthalate) copolymers (abbreviated PEBEPT) containing 2‐butyl‐2‐ethyl‐1,3‐propanediol (BEPD) for the whole range of compositions were prepared by bulk polycondensation of either terephthalic acid or dimethyl terephthalate as the diacid monomer with mixtures of ethylene glycol and BEPD. Polym…
This paper describes results obtained using an automated, crystallographically-based technique for twin identification. The technique is based on the automated collection of spatially specific orientation measurements by electron backscatter diffraction (EBSD) in the scanning electron microscope (SEM). The key feature…
昨今, コンクリート構造物からのコンクリート片の剥落が社会問題となっている.本文では, コンクリート片の剥落が生じた鉄道高架橋, 架道橋, およびこ線橋 (以下, 高架橋等とする) のかぶり, コンクリートの中性化深さ, 鉄筋腐食度などを調査し, 高架橋等からのコンクリート片の剥落要因を検討した. その結果, かぶり, 中性化残り, および雨水, 漏水の影響が, コンクリート片の剥落および鉄筋腐食と関係の深いことがわかった.
Deformation of a grain in polycrystalli ne metals is restricted or forced by deformation of neighbor grains during plastic deformation processes. It also gives influence to deformation of neighbor grains at the same time. Interaction between grains causes inhomogeneous local deformation and texture during plastic defo…
A novel lamellar silica mesostructure has been prepared using a silicone-based copolymer as the template under different conditions. The results demonstrated that the silicone copolymer with an unrestricted supramolecular configuration is responsible for the formation of the lamellar structure. Lamellar materials have…
Development of recrystallization texture in a IF steel containing 0.002wt% C, 0.0 6 wt% Ti is investigated by EBSD technique. Strong a-fiber texture, maximum at {112} is developed in cold rolled state, and strong ?-fiber texture which has maximum value at {111} is developed after annealing in salt bath. A technique to…
The new combined methodology for quantitative description of texture, structure and other microstructural parameters of thin layers using X-ray diffraction is presented and applied to the case of a ferroelectric thin film of Pb0.76Ca0.24TiO3 on a Pt/TiO2/SiO2/Si substrate. The approach allows the quantitative texture…
Novel amphiphilic poly(norbornene)s were prepared from two different monomers bearing a copper phthalocyanine and a branched hydrophilic side chain through a ring-opening metathesis reaction using a ruthenium initiator. The phthalocyanine moieties were contained as a side chain of the resulting poly(norbornene) backbo…
Abstract X‐ray reflectivity has been used to determine the mass uptake of probe molecules in porous thin films supported on thick silicon wafers. The adsorption occurs by capillary condensation when the films are exposed to probe vapor at controlled partial vapor pressures. The probe solvent partial pressure was varie…
Abstract The work presented here discusses a new technique for preparing silk fibers and films with persistent antimicrobial activity through use of metallic dyestuffs during the fiber dyeing process. The length of the silk fibers investigated contracted when the fibers were immersed in concentrated neutral salt solut…
In many applications where thin films are involved, like in electronics or ferroelectricity, it is required quantitatively to characterize their texture and residual stresses. Moreover, commonly the films contain several layers and phases, and due to the severe overlapping of the reflection peaks and sharp texture, th…
dimensional phase- field model is d eveloped to describe the cubic to tetragonal martensitic phase transformation in thin film attached to a substrate. Elastic solutions are derived for both elastically anisotropic and isotropic thin films with arbitrary domain structures, subject to the mixed stress -free and constra…
Abstract An inverted emulsion method for the synthesis of electrically conductive polyaniline–polystyrene blends of different compositions (10, 30, 50, 70, and 85%, wt/wt) is described. Polymerization of aniline is carried out in chloroform in the dispersed phase by using benzoyl peroxide as a novel oxidant and sulfos…
Abstract The effect of various benzenesulfonamide (BSA) plasticizers on the amorphous phase of semicrystalline polydodecamide (PA‐12) has been investigated. MonoBSAs appear as efficient glass‐transition temperature ( T g ) depressors because of their miscibility with the host polyamide (PA), low glass transition, and…
The mono-terminal hydroxyl groups of polybutadiene of varying chain length were studied as sites for initiation of lactone ring-opening polymerization by lipase catalysis. Novozyme-435 (immobilized Candida antarctica lipase B) was an effective catalyst for this acylation. Monohydroxyl-terminated polybutadiene with M n…
${\mathrm{PrTiFe}}_{11\ensuremath{-}x}{\mathrm{Co}}_{x}$ alloys $(x<~3)$ prepared by melting and subsequent annealing have been investigated with their carbides ${\mathrm{PrTiFe}}_{11\ensuremath{-}x}{\mathrm{Co}}_{x}{\mathrm{C}}_{y}$ $(y=1)$ synthesized by means of reaction with solid hydrocarbon at 750 K. X-ray di…
We describe a first passage time Markov chain analysis of rare events in kinetic Monte Carlo (kMC) simulations and demonstrate how this analysis may be used to enhance kMC simulations of dislocation glide. Dislocation glide is described by the kink mechanism, which involves double kink nucleation, kink migration and k…
Two 1D bi-bridging Cu(II) chains, catena-oxalate-bis[1-(2-aminoethyl)pyrrolidine-copper(II)]-0.5(squarate) perchlorate hydrate (1) and catena-pyrazine-oxalate-tetraaquo-dicopper(II) diperchlorate (2) have been synthesised and their molecular structures determined by X-ray crystallography. Compound 1 exhibits a polymer…
Abstract 60 Co‐gamma‐radiation and ceric ammonium nitrate (CAN) redox‐induced graft polymerization of acrylic monomers (acrylonitrile, acrylic acid, and methyl acrylate) to starch was performed to produce drug‐delivery systems. The grafted starches obtained mainly by redox‐induced polymerization were characterized by…
