Galvanic Corrosion
Current flow, weight loss, and polarization measurements have been carried out on the aluminum‐mild steel and zinc‐mild steel couples in normal NaCl solution at 25°C. Under a wide variety of experimental conditions both aluminum and zinc are anodic to mild steel and completely protect it against corrosion. In both gal…
Potassium Release Characteristics of Several Soils from Ohio and New York
Abstract Seventeen Ohio surface soils, 25 New York surface soils, and 21 New York subsoils were investigated. Potassium release characteristics were determined by continuous cropping and by four different chemical methods. A continuous leaching method employing the use of 0.01 N HCl gave the highest correlations with…
Marine Algae of the Northeastern Coast of North America

Ultraviolet Fluorescence of Some Ternary Silicates Activated with Lead
The fluorescence and phase diagrams of the following Pb‐activated ternary systems were investigated: ; ; ; . Eleven new ternary silicates were identified, some of which proved to be very good base materials for Pb‐activated phosphors with peak emissions ranging from 3000 to 4000Aå.
Lattice Constants and Brillouin Zone Overlap in Dilute Magnesium Alloys
The lattice constants of primary solid solutions of indium, aluminum, and cadmium in magnesium have been determined as a function of composition. A sharp change in ($\frac{c}{a}$) has been found only for magnesium-indium. The linearity of the ($\frac{c}{a}$) vs concentration curve for magnesium-aluminum has suggested…
Magnetocrystalline anisotropy in cobalt-substituted magnetite single crystals
The growth of single crystals corresponding to x=0 (high-purity magnetite), x = 0.01 and x = 0.04 in the composition series CoxFe3-xO4 is described. First- and second-order anisotropy constants of these crystals are determined by the torque method over the temperature range 120–450°K. The substitution of small amounts…

On the mechanism of work hardening in face-centred cubic metals, with special reference to polycrystalline copper
Tensile specimens of oxygen-free polycrystalline copper (99.9911%) were annealed for various periods in vacuo, in the range 500–700°C so as to obtain variations in the grain sizes and yield points. The initial rate of work hardening of all specimens was linear up to strains of about 1.5%, and independent of the magnit…
Effect of x‐rays and γ‐rays on synthetic polymers in aqueous solution
Abstract A study has been made of the effect of ionizing radiation (x‐ and γ‐rays) on aqueous solution of the following vinyl polymers: polymethacrylic acid, polyacrylic acid, polyacrylamide, polystyrene sulfonate, polyvinylpyrrolidone, and polyvinyl alcohol. In dilute solutions (<0.3% for the samples of polymer us…
Electrodeposition of Metals from Organic Solutions
Numerous nonaqueous solutions of Ti and Zr compounds were electrolyzed in an attempt to electrodeposit the metals. Ether solutions containing halides, hydrides, borohydrides, and organo‐metallic compounds of Ti and Zr were the most promising. A mixed type of bath containing both hydrides and borohydrides yielded Ti‐Al…
Schwingungsspektren von Schmelzen, Gläsern und Kristallen des Natrium‐di‐, tri‐ und ‐tetraphosphats
Abstract Es werden Schwingungsspektren von Schmelzen und Gläsern im System NaPO 3 −Na 4 P 2 O 7 beschrieben und zugeordnet. Tri‐ und Tetraphosphatanionen liegen bei Temperaturen kurz oberhalb der Liquidus‐Kurve im System NaPO 3 /Na 4 P 2 O 7 bei stöchiometrischer Zusammensetzung der Schmelze weitgehend als definierte…

Water Transport Mechanisms in Textile Materials
In view of the interest in the phenomenon of "wicking" in apparel fabrics made of synthetic fibers or of blends, a basic study of the mechanism of water transport in yarns and fabrics has been made. The movement of water along fabrics is shown to depend on the laws of capillary action. Because the rates of travel of w…
Ferromagnetic Resonance in Metal Single Crystals
Microwave susceptibility expressions for ferromagnetic resonance have been derived for metal single crystals possessing crystalline anisotropy. Crystals of uniaxial and cubic magnetic symmetry are considered. When the magnetization M is aligned with the applied field H, the results are equivalent to those of Kittel. W…
