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…

Identification of Titanium Oxides by X-Ray Powder Patterns.
X-ray powder data are given for fifteen phases occurring in the titanium --oxygen system. (auth)
Anodic Formation of Oxide Films on Silicon
Dense oxide films have been formed anodically on p ‐ and n ‐type single‐crystal Si in connection with the electrical properties of Si surfaces. Concentrated or permit forming, but the highest voltage obtainable is less than 200 v. A solution of in N ‐methylacetamide permits forming to 560 v, and is also preferable in…

Cordierite-indialite relations
Presents a revised structural classification of minerals of the cordierite group on the basis of optical and x-ray studies of natural and artificial material which have shown the existence of a number of structurally intermediate states between indialite (hexagonal) and common cordierite (pseudohexagonal).
Magnetic Properties of TiFe2O4-Fe3O4 System and Their Change with Oxidation
A series of solid solution xTiFe2O4.·(1-x) Fe3O4 was synthesized by ceramic method over a whole range of the composition, 1≥x≥0. Changes of the Curie point, saturation moment and the lattice parameter with the composition were examined. Generalized titanomagnetite having some vacant site in the structure normally occu…
Galvanic Cells for the Determination of the Standard Molar Free Energy of Formation of Metal Halides, Oxides, and Sulfides at Elevated Temperatures
The use of electromotive force measurements on galvanic cells for the determination of standard molar free energies of formation of halides, oxides, sulfides, and other compounds at elevated temperatures is surveyed. New potentialities and inherent limitations are shown. Formulas for the estimate of errors resulting f…
Zur Rückstreuung von Elektronen im Energiebereich von 10 bis 100 keV
Abstract Gerichtete Elektronenstrahlen mit einer Primärenergie von 10, 30, 50 und 70 keV werden an Al, Cu, Ag und Au gestreut und dabei die Energie‐ und Winkelverteilung der Streuelektronen gemessen. Aus den Meßergebnissen lassen sich für einen Elektronenstrahler, der die Elektronen richtungsisotrop emittiert, die Ene…

On the Period of Out-of-step of Ordered Alloys with Anti-phase Domain Structure
The period of out-of-step of ordered alloys with anti-phase domain structure, measured in atomic distance, is generally not an integer, in spite of sharp splits of superlattice reflections. This fractional property of the period has theoretically been examined. The general treatment of this problem has shown that a re…

Ceramic Properties of Samarium Oxide and Gadolinium Oxide; X‐Ray Studies of Other Rare‐Earth Oxides and Some Compounds
Samarium oxide forms a ceramic of medium strength and density (6.0) when it is fired at 1300°C. When it is fired at 1500°C., its density is increased to 7.4 but it loses its stability toward boiling water. X‐ray data are given concerning the structure of the oxide as received and at 1300°C. and of the reaction product…
Some Unusual Effects of Hydrogen in Corrosion Reactions
Consideration of corrosion in the presence of water has led to the postulation of damage by hydrogen produced in the reaction. For cases where the metal surface is covered with a protective layer, it is considered that some hydrogen ions diffuse through the layer and form hydrogen atoms beneath it. The consequence of…
Magneto-resistance in metals
Experiments are reported in which novel results are found on the magneto-resistance of sodium and rubidium. Measurements have been made both on plate-like specimens which show very strong anisotropy in the magnetic field, and on a cylinder of diameter large comparedwitli the mean free path, ι, of the electrons.
