Theory of the Ferroelectric Effect in Rochelle Salt
Mueller's phenomenological theory of Rochelle salt, NaK${\mathrm{C}}_{4}$${\mathrm{H}}_{4}$${\mathrm{O}}_{6}$\ifmmode\cdot\else\textperiodcentered\fi{}4${\mathrm{H}}_{2}$O, has been generalized, and the properties of the clamped crystal described. A local field theory of the clamped crystal has been developed on the b…

Aluminum in Soils: I. Extraction Methods and Magnitudes in Clays and Ohio Soils
Abstract Various procedures were used for extraction of Al from Ohio soils representing a wide range in extractable Al. One normal NH 4 OAc at pH 4.8 was selected as an extracting solution because of its superiority over Ba(OAc) 2 and BaCl 2 . One normal NH 4 OAc plus 0.2 N BaCl 2 was no better than NH 4 OAc alone. At…
THE SOLUBILITY OF ALUMINUM HYDROXIDE IN ACIDIC AND BASIC MEDIA AT 25 °C
The solubility of Al(OH) 3 was measured in NaOH and HClO 4 solutions. Possible reactions of Al(OH) 3 in dilute NaOH and HCIO 4 solutions are indicated along with the calculated constants. The amphoteric hydroxide was found to be more acidic than basic. The isoelectric point of Al(OH) 3 was determined to be pH 7.7.

Oxidation Behavior of Silicon Carbide
The oxidation of purified green silicon carbide in controlled atmospheres was studied by weight‐gain measurement and by observation of the surface reaction products, including optical measurement of the thickness of the oxide surface film. The rate of oxidation was much greater for silicon carbide in contact with flui…

The X‐ray diffraction, birefringence, and infrared dichroism of stretched polyethylene. II. Generalized uniaxial crystal orientation
Abstract A general method for describing the crystal orientation in a uniaxially oriented crystalline polymer is presented. It is shown that two orientation functions may be quantitatively evaluated from x‐ray diffraction data. The variation of these during mechanical and thermal treatment may be studied. These functi…

Refractive Index of Arsenic Trisulfide
The refractive index of a sample of As2S3 was determined at three temperatures near 19°, 25°, and 31°C for selected wavelengths in the range 0.57 μ to 11.8 μ. A five term Sellmeier type dispersion equation was fitted to the averaged data reduced to 25°C; four of the constants were chosen to approximate an absorption c…

Fine Structure in the Absorption-Edge Spectrum of Si
Measurements of the absorption spectrum of Si, made with high resolution, near the main absorption edge, at various temperatures between 4.2\ifmmode^\circ\else\textdegree\fi{}K and 415\ifmmode^\circ\else\textdegree\fi{}K, have revealed fine structure in the absorption on the long-wavelength side of this edge. This str…
The adsorption theory of passivity and the flade potential
Abstract From quantitative data reported by various investigators, it is concluded that the primary passive film on iron has the following properties: (1) 25–100 Å thick, (2) equivalent to 0.01 coulomb/cm 2 , (3) can oxidize CrO − 2 to CrO −− 4 , (4) follows the (Flade) potential relation —0.58 + .058 p H (volts).

The Internal Friction of Barium Titanate Ceramics
The internal friction of BaTiO 3 ceramics has been studied under various conditions. It depends on temperature, biasing field and vibration amplitude, but is nearly independent of frequency and porosity. It is concluded that its main part is not caused by the ceramic and domain structures but is the property of the si…
Korrosion und Passivität
Abstract Die Korrosionsvorgänge und Passivitätserscheinungen der metallischen Werkstoffe sind elektrochemischer Natur. Auf Grund dieses Zusammenhanges werden an Hand potentiostatischer Stromspannungs‐diagramme die charakteristischsten Erscheinungsformen der Metallpassivität erläutert. Es wird gezeigt, daß der passive…
SULFURIC ACID IN DESMARESTIA
1. Brilliant cresyl blue accumulates in the vacuoles of Desmarestia munda and D. herbacea and the accumulated dye appears purple, indicating that the pH of the vacuolar sap is less than 1.0 or greater than 7.5. However, the expressed saps of these two brown algae have pH 1.0 or less and about 2.0, respectively. The ou…
Peroxide crosslinked carbon black polyethylene compositions
Abstract Polyethylene containing large quantities of carbon black can be crosslinked by a chemical free radical mechanism utilizing the thermal decomposition of dicumyl peroxide as the source of free radicals. Crosslinking in the presence of different types of blacks was studied in a liquid paraffin model system. The…

29—THE MECHANICS OF TWISTED YARNS: THE INFLUENCE OF TRANSVERSE FORCES ON TENSILE BEHAVIOUR
An idealized theoretical model of a yarn is assumed, and, after considering the stresses acting on a small element of the yarn, the conditions for radial equilibrium in the yarn are worked out. This leads to expressions for the tensile and transverse stresses in the fibres as functions of (i) the position in the yarn,…
