Effect of Oxygen, Chlorides, and Calcium Ion on Corrosion Inhibition of Iron by Polyphosphates
Data are presented showing that sodium polyphosphates are effective corrosion inhibitors for steel, provided the dissolved oxygen concentration is above a critical minimum. Presence of calcium ion appreciably improves inhibition under all conditions. In solutions containing less than the critical amount of oxygen (1 m…
The degradation of cellulose by ionizing radiation
Abstract When subjected to the effect of ionizing radiation, such as atomic pile radiation or gamma radiation, cellulose is rapidly degraded into a powdery material. A theoretical treatment shows that if the effect of radiation is to cause fracture at random in the main chain, the relation between intrinsic viscosity…
Unusual orientation phenomena in polyethylene interpreted in terms of the morphology
Abstract In the first part of the paper various orientation phenomena of the drawing‐relaxation behavior are interpreted in terms of the changes occurring within the submicroscopic helices which form the spherulites. Not only drawing and relaxation but also the redrawing of the relaxed samples were followed, and it wa…
The Electrochemical Behavior, Including Hydrogen Overvoltage, of Iron in Acid Environments
The corrosion rate of pure iron in deaerated acid media was studied as a function of p H. The rate was found to be essentially independent of p H over the range 1–4 in 4% sodium chloride. Potential and polarization measurements are used to explain this behavior. A method for calculation of corrosion rates from electro…

Magnetostriction and Magnetomechanical Effects
The energy of a ferromagnetic substance comprises three parts, the exchange, anisotropy and magnetostatic (demagnetizing) energies. These all vary with the state of strain of the substance and so it will deform spontaneously if the deformation reduces the total energy (equal to the sum of the magnetic energy and the e…
Factors Affecting Thermal Stress Resistance of Ceramic Materials
The sources and calculation of thermal stresses are considered, together with the factors involved in thermal stress resistance factors. Properties affecting thermal stress resistance of ceramics are reviewed, and testing methods are considered.

On the relations between structure and morphology of crystals. I
An attempt is made by Hartman & Perdok to find relations between crystal structure and crystal morphology on an energy basis. It is concluded that the morphology of a crystal is governed by chains of strong bonds running through the structure.

Electrical and Optical Properties of Indium Selenide
The electrical and optical properties of InSe have been investigated with single crystals of the compound. The spectral dependence of the optical absorption coefficient and of the photoconductivity was measured. The optical absorption edge was not sufficiently well defined for the band gap to be estimated unambiguousl…
