Abstract The β relaxation of a phenoxy resin and a number of related uncured and cured bisphenol‐type epoxide resins was studied using a torsion pendulum. Two molecular mechanisms are proposed to contribute to the β relaxation in the range from −55 to −80°C. One is the motion of the hydroxyether group and the other is…
The initial stages of oxidation of clean, high-purity, iron foil have been studied using a Kratos ES 300 electron spectrometer with monochromatic X-radiation. Through careful observation of the Fe 2p peak profile, peak energy maximum, and peak satellite structure, it was possible to identify oxide species containing F…
Ferromagnetic resonance (FMR) has been used to study a wide variety of very thin single crystals of Fe grown on (110) GaAs substrates by molecular beam epitaxy. Data were taken at room and liquid nitrogen temperatures for films with thicknesses L in the range 18–200 Å. Due to surface anisotropy, the easy axis of the m…
Ba-ferrite films have been prepared by means of Targets-Facing type of sputtering method which is very useful to prepare magnetic films at high rate without any bombardment of high energy particles such as γ-electrons and negative ions emitted from the targets and is favorable to obtain stoichiometric films of good qu…
Specific-heat measurements on the organic solid di-tetramethyltetraselenafulvalenium-perchlorate ${(\mathrm{TMTSF})}_{2}$ Cl${\mathrm{O}}_{4}$ demonstrate that ${T}_{c}$ decreases as much as 22%, when the cooling rate below 40 K is changed from 0.1 K/min (relaxed state) to 10 K/min (quenched state). The phenomenon is…
A multislice formula for many-beam calculation of dynamical electron diffraction amplitudes which may be applied for inclined illumination has been derived based on the Schrödinger equation. This formula clearly shows the following points: a specimen should be considered as sliced parallel to the entrance surface; a s…
Photon correlation spectroscopy was performed on a dilute bcc colloidal crystal in a thin-film cell to measure its response to thermal fluctuations with wave vectors along lattice symmetry directions. The phonon dispersion curves show a definite harmonic-lattice behavior for longitudinal and transverse modes. We prese…

New details of NADPH binding to Lactobacillus casei dihydrofolate reductase have become visible as a result of crystallographic refinement to an R factor of 0.152 at 1.7 A resolution. Conformational torsion angles for bound NADPH have been extensively revised and specific interatomic contacts responsible for cofactor…

Abstract Drawn nylon 6 filaments were subjected to swelling treatment with benzyl alcohol and aqueous solution of phenol and formic acid under slack condition and under tension. The pretreated samples were dyed with a disperse dye Foron Yellow SE‐FL (C.I. Disperse Yellow 42). A considerable increase in the equilibrium…
The paper discusses effects of bending on domain configurations and losses of HI-B sheets with stress coating. Two-dimensional loss topograms were determined using a new test system based on raster-scanning the specimen surface with a thermistor. For longitudinal bending, considerable loss increases resulted. Transver…
This paper discusses the effects of demagnetization on domain configurations of HI-B sheets with stress coating. Demagnetization frequency was varied between 5 Hz and 1 KHz. As frequency increased, considerable refinement of main domains resulted, especially for wide domains. Its extent was a maximum close to 10 Hz an…
Abstract A phosphorus‐ and nitrogen‐containing polyl is prepared by condensing tetrakis(hydroxymethyl)phosphonium chloride with diethanol amine in aqueous medium. The newly synthesized polyol‐bis(hydroxymethyl)‐ N , N ‐bis(2‐hydroxyethyl)aminomethylphosphine oxide (AMPO) is used in the preparation of rigid polyurethan…

Abstract A laboratory cutting and chipping test for off-the-road, (OTR) and heavy duty, (HD) tires has been developed that predicts service performance with reasonable speed and accuracy. It makes possible the investigation of many compounding factors quickly and inexpensively. A test can be made on a sample in the sh…
Experimental results for some physical properties of Li 2 O‐B 2 O 3 and SrO‐B 2 O 3 glasses with high modifier content showed anomalies in the composition dependence of many properties such as thermal expansion coefficient, transformation temperature, softening temperature, density, and refractive index at 30 to 33 mo…
We develop a model of superexchange interactions in W-hexagonal ferrites. We analyse all possible interactions and classify the exchange energies from structural considerations. The spin configuration deduced from the model is in agreement with experimental results. Finally, the effect of preferential substitutions on…
