THE BEHAVIOR OF MONOLAYERS OF PROGRESSIVELY FLUORINATED FATTY ACIDS ADSORBED ON WATER
A study was made on the force-area, surface potential-area, and surface moment-area relations of monolayers of two series of progressively fluorinated fatty acids spread on water at various pH values. The series were n-heptadecanoic acids with substitutions in the 17-position of perfluoromethyl, perfluoropropyl, perfl…
Some Dielectric and Optical Properties of KD2PO4
The Curie point of KD2PO4 is found to be 222°±1°K, which is 9°K higher than previously reported. It is believed that the higher value is due to more complete deuteration. Other physical properties (at room temperature unless otherwise noted) are as follows: dielectric constant from 208° to 300°K; contour shearmode res…
The work-hardening characteristics of Cu and α-brass single crystals between 4•2 and 500°K
Abstract Shear stress—shear strain curves of Cu and α-brass single crystals have been obtained over a wide range of alloy compositions, temperatures, initial orientations and strain rates. Analysis of the work-hardening characteristics leads to the following main conclusions: (i) for Cu the work-hardening rate during…

Changes in Polybutadiene Rubber under Various Conditions of Aging
Abstract 1. The systematic relations of the oxidation of SKB under the action of heat, light, and ionizing radiation are considered and it is shown that the formation of a series of oxygen-containing products takes place (hydroperoxides, alcohols, aldehydes, ketones, acids, ethers, and esters). The general tendency fo…

Far ultra-violet absorption spectra of cerium(III) and europium(III) aqua ions
The far ultraviolet absorption spectra of Ce and Eu is reported and discussed. The relatively broad and weak electron transfer bands were found to have the lowest wave-number in the most oxidizing central ion, Eu(III). A solution of 0.03 M Eu(III) perchlorate in 0.1 M HClO4 shows a maximum at 188 m mu , with the molar…
Structural and Magnetic Characteristics of TiFe2–ZrFe2 and ZrCo2–ZrFe2 Alloys
Structures and unit-cell dimensions for a number of alloys of TiFe2–ZrFe2 and of ZrCo2–ZrFe2 have been determined at room temperature, and the magnetic properties of alloys of the two systems have been investigated over a range of temperature extending from 4° to 650°K. Results for the TiFe2–ZrFe2 system show two term…
Effect of Crystal Orientation on Plastic Deformation of Magnesium Oxide
Stress‐strain data for single crystals of MgO tested in compression with 〈110〉 and 〈111〉 loading axes are presented for temperatures ranging from 26〉 to 1250°C. Stress‐strain data for polycrystalline MgO are also presented over the same temperature range. Single crystals with a 〈111〉 loading axis were found to deform…
Phase Equilibria in the System CaO—MgO
The liquidus, solidus, and subsolidus of the system CaO–MgO have been redetermined. X‐ray diffraction and optical techniques show that the maximum solid solution of MgO in the CaO lattice is approximately 17 wt% at 2370°C and the maximum solid solution of CaO in the MgO lattice is approximately 7.8 wt% at 2370°C. The…
Neutron Diffraction Study of the Intermetallic Compound FeSi
A powder neutron diffraction study has been made on the intermetallic compound, FeSi. From magnetic measurements this substance has been believed to be antiferromagnetic below 170°C. Neutron diffraction measurements at room temperature and at liquid nitrogen temperature, however, show no coherent antiferromagnetic int…

Use of Lithium Aluminum Hydride in the Study of Surface Chemistry of Carbon Black
Abstract Considerable interest has been focused in recent years on the effects of carbon black surface chemistry on its properties in rubber and other polymer systems. Methods have been developed in our laboratory for the quantitative characterization and description of the surface chemistry of carbon blacks. The tota…
A Study of Sulfenamide Acceleration
Abstract Sulfenamide—sulfur curing systems containing zinc oxide and stearic acid respond to both ionic and radical reaction conditions. Scorch delay and rate of the vulcanization are determined by the basicity and steric structure of the amine forming the amide, and by the accelerator-sulfur ratio. Sulfenamides deriv…

The effect of quenching history, quenching temperature and trace impurities on vacancy clusters in aluminium and gold
It has been shown that in zone-refined aluminium, under specific quenching conditions, regions of stacking fault bounded by dislocation loops with a 1/3 [111] Burgers vector can be formed. The same type of defect can be produced by multiply quenching 99•995% aluminium. Repeated quenching therefore produces effects sim…
The fine structure of fibers and crystalline polymers. III. Interpretation of the mechanical properties of fibers
Abstract The mechanics of extension of plant fibers is considered in terms of a spiral arrangement of crystalline fibrils embedded in a noncrystalline matrix. Deformation may take place either by stretching of the fibrils or by extension such as that of a spiral spring. In the latter, the major resistance comes from t…
