Photographic sensitivity
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.…

Microwave Resonance Relations in Anisotropic Single-Crystal Ferrites
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…
Anodic Oxidation of Aluminum, Chromium, Hafnium, Niobium, Tantalum, Titanium, Vanadium, and Zirconium at Very Low Current Densities
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.…

Solution behavior of chemically synthesized polyglucoses
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…

Dependence of the Ratio of Piezoelectric Coefficients on Density and Composition of Barium Titanate Ceramics
The ratio of piezoelectric coefficients $\ensuremath{-}\frac{{d}_{33}}{{d}_{31}}$ was found to decrease from about 2.5 for polarized barium titanate ceramic of high porosity to 2.2 for porosity near zero. The ratio increases up to 2.9 for ceramic with 2% porosity containing 12 weight% calcium titanate. For single crys…

The Corrosion of Single Crystals and Recrystallized Single Crystals of Iron and Steel in Citric Acid
Corrosion studies, largely in 0.2M citric acid at 20°C and the boiling point, were made on polycrystalline disks and monocrystalline spheres and disks of Armco iron and type L steel. Preliminary experiments indicated that the (100) face corroded at the slowest rate and the minor faces, of which the (321) is an example…
