The sorption isotherms of several fibres, of different types and structures, have been determined by a gravinietric method. The experiniental results obtained can be used in the confirmation of the equations of Hailwood and Horrobin, which were obtained by considering fibre–water systems as solutions of water in the d…
Abstract The polarized infrared spectra of isotactic polybutene-1 in a hexagonal form will be measured in the region from 4000 to 700 cm−1. The normal vibrations of this polymer, which takes a three-fold helical conformation, will be calculated by the use of the GF-matrix method, with the modified Urey-Bradley force f…
Detailed measurements of electrical conductivity (σ), Hall coefficient (R H ), and Seebeck coefficient (α) were made on seven bismuth telluride samples of composition Bi 2 Te 3+x , with x ranging from −0.06 to +0.48. Above room temperature the slope of R H T 3/2 gave an apparent energy gap about 50% higher than that f…
A general expression of the magnetic anisotropy energy and the magnetoelastic energy in the crystal of magnetic symmetry D 3 d is obtained. It is shown that, in NiO, the easy directions of magnetization will be either turnrightup.eps[1\bar10] or directions very close to turnrightup.eps[11\bar2] when the easy plane is…
The promotion of n ‐type electronic conduction by relatively small concentrations of donors in the presence of a large concentration of calcium, which is an acceptor, is explained by assuming that most of the calcium is present as neutral calcium ion‐oxygen vacancy pairs or clusters. Evaluation of experimental data on…

The structure of post-irradiation annealed UO2 has been examined by transmission electron microscopy to try to understand the behavior and release of fission gas.At a dose of 2.2 × 1019 fissions/cm3, 5 × 1015 small gas bubbles/cm3 are observed in the material. These precipitate at 1100°C and appear to grow from 25 to…

Samples of the titanium oxides with O/Ti ratios between 0.5 and 1.67 were prepared by heating mixtures of Ti and TiO 2 in high vacuum to 1500°C and annealing them in silica ampuls at 900° to 1100°C. Results of chemical and X‐ray analyses are combined with previously published data to form a complete phase diagram. The…
Photochemical decomposition of matrix-isolated carbon suboxide at 4.2°K with 1470-Å light produces highly reactive carbon atoms, presumably from an observed CCO intermediate. Reactions of carbon atoms with nitrogen lead to the observation of the infrared absorptions of the NCN and CNN radicals. Attempts to form methyl…

Abstract The preparation of five samples of poly(methyl methacrylate) covering a wide range of tacticity and their electron irradiation to produce series of varying molecular weight are described. The glass transition temperature T g of each polymer was determined by DTA techniques. Plots of T g and the reciprocal of…
The influence of cell age, cell size, cell shape, and mode of colony formation on diatom sinking rates was investigated in 26 experiments with Skeletonema costatum (Grev.) Cleve and Rhizosolenia setigera Brightwell. The mean sinking rate of S. costatum ranged from 0.30 to 1.35 m/day; the absolute minimum and maximum r…

Numerical calculations of the powder pattern of the central component shifted by the second-order nuclear quadrupole interaction in solids have been performed for various values of the asymmetry parameter, η. Shape functions have been obtained in units of (νQ2/6νL) (a—¾) for η=0.1, 0.2, ···, 1.0, at 0.1 intervals. Als…
Abstract Intercrystalline links in polyethylene have been revealed by crystallizing from the melt mixtures of fractionated polymer and the linear hydrocarbon n ‐C 32 H 66 , the latter constituent being removed later by washing at room temperature in an organic solvent. These fibrous links measure up to 15,000 A. in le…
