This report discusses the application of electron magnetic resonance techniques to defect and impurity sites in solids, conduction electrons in metals, ferromagnetic, ferrimagnetic and antiferromagnetic materials. It also reviews the recent experiments on cyclotron resonance in semiconductors together with a brief acc…

Certain of the criteria used for distinguishing vermiculites in clays from smectites are critically examined, and attention is drawn to the urgent need for further esearch in this field. Difficulties inherent in the differ-entiation are heightened by the common occurrence of interlayer con-tamination in the naturally…

The infrared spectra of finely powdered samples in pressed disks of KBr have been obtained for sulfamic acid, sodium and potassium sulfamates, and the corresponding deutero-compounds in the region from 4000 to 500 cm—1 at several temperatures. Satisfactory vibrational assignments could be made for the zwitterion model…

Glasses have been made in the systems and with contents ranging between 50 and 87 mole%. The glasses were found to be semiconductors, those with the highest contents having a specific conductivity of the order of 10 −5 ohm −1 cm −1 at room temperature. The relationship between the specific conductivity, σ, and the tem…

This paper reviews the experimental and theoretical work on photographic sensitivity and related topics which has been published during the past ten years. New experimental results, obtained to a large extent with model systems, have necessitated substantial revision and amplification of previously accepted theories.…

The ferromagnetic resonance relations in magnetically anisotropic single-crystal ferrites have been re-examined. Detailed analyses are presented for spherical ferrite specimens possessing first order anisotropy. Generalized nomograms are presented which relate the microwave resonance frequency to the static magnetic f…
Some aspects of the mode of formation of anodic oxidation films in the potential region below oxygen evolution were examined for a number of metals under as nearly constant experimental conditions as possible. The metals selected were Al, Ti, Hf, V, Nb, Ta, and Cr. Results for Zr were reported in earlier publications.…

Abstract The solution behavior of polyglucoses prepared by the acid catalyzed polycondensation of Pacsu and Mora is discussed. According to this method glucose enters the polycondensation through the hemiacetal hydroxyl joining any of the other hydroxyls of a second glucose unit. Branching occurs up to the functionali…
