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…

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…
Temperature‐composition relationships have been measured in the and the systems in the areas of liquidus temperatures below 1000°C. A binary eutectic composition of and was observed to melt at 769°C. A ternary eutectic composition of , , and was observed to melt at 672°C.

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…

Current flow, weight loss, and polarization measurements have been carried out on the aluminum‐mild steel and zinc‐mild steel couples in normal NaCl solution at 25°C. Under a wide variety of experimental conditions both aluminum and zinc are anodic to mild steel and completely protect it against corrosion. In both gal…
Abstract Seventeen Ohio surface soils, 25 New York surface soils, and 21 New York subsoils were investigated. Potassium release characteristics were determined by continuous cropping and by four different chemical methods. A continuous leaching method employing the use of 0.01 N HCl gave the highest correlations with…

The fluorescence and phase diagrams of the following Pb‐activated ternary systems were investigated: ; ; ; . Eleven new ternary silicates were identified, some of which proved to be very good base materials for Pb‐activated phosphors with peak emissions ranging from 3000 to 4000Aå.
