XIV. The distribution of electrons round impurities in monovalent metals
Summary A theoretical investigation is made of the distribution of electrons round a positively charged impurity dissolved in a monovalent metal. Applications are made to dissolved hydrogen, where the impurity is a proton, and to atoms such as zinc, gallium, etc., which are usually considered to contribute their elect…
Theory of Conductivity of Semiconductors
The author's older theory of conduction in polarizable media is generalized in such a way as to include rectification. An electronic component (positive holes or electrons) and an ionic component (negative or positive ions) are taken into account. The former are subjected to the boundary conditions of the MottSchottky…
High Capacity Magnesium Dry Cells
Magnesium dry cells patterned after the conventional Leclanché cell now appear to be worthy of acceptance in many applications. The cell contains a magnesium alloy anode, , magnesium bromide electrolyte inhibited with lithium chromate, and a paper separator. The cell is characterized chiefly by very high capacity, par…

Time‐dependence of boundary tensions of solutions. II. Experimental determination of the kinetics and equilibrium of adsorption at liquid‐liquid interfaces
Abstract Boundary tensions have been measured by the method of pendent drops for the interfaces between water and solutions of long‐chain fatty acids in hexane over a wide range of concentrations. At low concentrations the interfacial tensions were independent of the age of the surface. But above what appeared to be a…

The Thermal Dependence of the Elastic Moduli of Polycrystalline Graphite
Young's modulus and the shear modulus of grade SA-25 molded graphite and grade AUF extruded graphite were measured as functions of temperature in the range from 25°C to 2000°C. In the case of the extruded material, variations of the two moduli with position and direction relative to the axis of extrusion were also inv…
