Measurements have been made of the Curie points and magnetic moments of three series of compounds (Laves phases) $M{\mathrm{Ir}}_{2}$, $M{\mathrm{Os}}_{2}$, and $M{\mathrm{Ru}}_{2}$, where $M$ is a rare-earth element. The Curie point is highest (85\ifmmode^\circ\else\textdegree\fi{}K) for the compounds containing Gd a…
Electron-spin resonance of bound substitutional nitrogen donors in diamond is observed and discussed. The $g$ factor is isotropic at 2.0024\ifmmode\pm\else\textpm\fi{}0.0005. For a given donor, one of the C-N bond directions is a hyperfine axis with constants $A=40.8$ oersteds, $B=29.2$ oersteds. There are thus four t…
Abstract Metallorganische Verbindungen reagieren in verschiedener Weise mit molekularem Sauerstoff. Alkyl‐Metall‐Verbindungen werden zu Metallalkyl‐peroxyden oxydiert. Aus den Alkali‐Addukten aromatischer Kohlenwasserstoffe entstehen Alkali‐peroxyd und Kohlenwasserstoff. Aryl‐Metall‐Verbindungen schließlich ergeben al…

External and internal factors influencing the rate and distribution of corrosion are discussed. Among the external factors considered are: pH of the solution, influence of elements acting as inhibitors or as stimulants of corrosion, the concentration of neutral salts, the temperature of solution and the rate of soluti…
The Hall coefficient and transverse magnetoresistance of two type II-b semiconducting diamonds (p-type) were measured as a function of magnetic field from 500 gauss to 20 000 gauss at fixed temperatures between 0°C and 100°C. These diamonds have R σ values of about 1000 cm 2 v -1 sec -1 at room temperature. The Hall c…

The effect of the short fiber content of a cotton on yarn and fabric properties and processing efficiency, long a speculative and controversial subject, is investigated to a limited extent in this paper by the technique of cutting sliver into and ¼- and ½-in. segments and adding the resulting short fibers to the paren…
Summary Studies are described of various specimens of diamonds made by the General Electric Company of New York, and by Allmänna Svenska Elektriska Aktiebolaget, Västeras, Sweden. The G.E. synthetic diamonds always contain single crystal inclusions of nickel or of a Ni-rich face-centred cubic compound. These are stric…
Abstract 1. The highest hydrogenation activity was obtained when the silk-palladium catalyst was prepared by boiling the silk fibroin fibers with 0.1% palladous chloride solution in 0.1 n acetic acid for 8 min. and then hydrogenating the resulting chelate. 2. The catalyst prepared as above was, however, devoid of the…

Two independent, three-dimensional sets of intensity data have been collected from two different crystals of basic beryllium acetate (Be40(CH3COg)8 , cubic, /~d3, a 0 = 15.74 A, Z = 8). An Eulerian cradle Geiger counter spectrometer was employed for the measurements. Two crystals were surveyed so as to insure against…
The magnetic susceptibilities of six spin-free tetrahalo complexes of bivalent cobalt, CoX4—2 (X=Cl—, Br—, I—), have been investigated over a temperature range and found to exhibit satisfactory dependence on the Curie-Weiss law. The magnetic moments were found to be in the order predicted by crystal field theory, viz.…

Abstract The rate of reaction of ceric nitrate with the 1,2‐glycol units and the alcohol units of polyvinyl alcohol was determined at 20°C. It was found that the glycol units are oxidized much faster than the alcohol units even though they are outnumbered about one hundred to one in the polymer chain. Under the condit…
Techniques have been developed to extend the measured electric field dependence of the sidewise 180\ifmmode^\circ\else\textdegree\fi{} domain-wall velocity in liquid-electroded BaTi${\mathrm{O}}_{3}$ crystals. The wall velocity data now cover about eight decades of velocity. The wall velocity is given by ${v}_{\ensure…

Differential spectra have been obtained of a number of irradiated polyamides and monomeric amides. These spectra indicate that both free radical and molecular products are produced as primary products. The transient colored products (which are believed to be free radicals) and molecular products appear to be in the am…
Diisocyanates condense readily with hydrazine or hydrazine hydrate to give polyureylenes with the structure: Similarly, dihydrazides (NH2NHCOR′CONHNH2) condense with diisocyanates to give polymers with the structure: Tough films and fibers can be prepared from these polymers by conventional techniques. Solutions of s…
