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…

The Temperature Dependence of the Solubility of Solid Nonelectrolytes
The solubilities of nonelectrolytes in solutions from which chemical interactions are absent, when plotted as logarithm of mole fraction vs logarithm of absolute temperature, yield practically straight lines except near the melting point of the solute. This offers a superior method of smoothing out solubility data and…
THE MECHANICAL CHARACTERISTICS OF PNEUMATIC TIRES
AN EXPOSITION OF EXISTING KNOWLEDGE OF MECHANICAL PROPERTIES, CHARACTERISTICS AND BEHAVIOR OF PNEUMATIC TIRES IS PRESENTED. QUESTIONS OF TIRE TECHNOLOGY ARE NOT DISCUSSED. THE ROLLING PROCESS, VERTICAL AND HORIZONTAL LOAD-DEFLECTION CHARACTERISTICS, BEHAVIOR DURING BRAKING AND SIDEWAYS MOTION, ROLLING RESISTANCE AND H…
Column Behavior Under Conditions of Impact
The magnitude of the stress introduced into a long slender bar t>y velocity impact depends only upon the conditions of impact. Thus, buckling of this bar under impact loading can only take place after the compressive stress wave has propagated over a critical'' length of the bar. Column behavior under impact is studie…

The Diffraction of X-Rays by Distorted-Crystal Aggregates III: Remarks on the Interpretation of the Fourier Coefficients
The line profile of the h th order reflection from a set of lattice planes is known to be given by a Fourier series with coefficients A(h,m)=N(m)J(h,m) . The function N(m) depends on the particle shapes and sizes, and J(h,m) depends on the state of strain Neither can be completely determined from the experimental Four…
The Uranium-Carbon System
An investigation of the uranium‐carbon system has been made and a constitutional diagram drawn on the basis of melting point, x‐ray, and metallographic data. Three carbides of uranium have been detected and identified: , , and . No compounds have been found containing a carbon content higher than that of . and are com…
Kinetics of Decomposition of Nitric Oxide at Elevated Temperatures. I. Rate Measurements in a Quartz Vessel
The rate of thermal decomposition of nitric oxide has been measured in a quartz vessel from 872 to 1275°K. The reaction follows a second-order rate law over the range of temperatures studied. Variations in the surface-to-volume ratio of the reaction vessel indicate the predominance of a heterogeneous mechanism at temp…
A Method for Determining Young's Modulus of Glass at Elevated Temperatures
Because of the experimental difficulties imposed by the prominence of delayed elastic and viscous effects, little investigation has been made of the instantaneous elastic modulus of soda‐lime‐silica glasses above approximately 500°C. The method described in this paper provides a means of measuring the Young's modulus…

Contribution to the Theory of Cathodic Protection
The distribution of the electrical potential inside an electrolytic solution is calculated for typical cases of cathodic protection with the aid of an auxiliary metal to be sacrificed. These calculations are used to work out equations and diagrams which permit prediction of the maximum extension of metallic surfaces f…

A new analytical method for solving complex crystal structures
With the aid of an identity it is shown that relationships between signs of structure factors for centre-symmetrical crystals can be obtained even when the Haxker-Kasper inequality considerations yield no useful information.. It is shown that a structure determination can be formulated as a self-consistency problem wi…
Nuclear Quadrupole Effects and Electronic Structure of Molecules in the Solid State
Measured nuclear quadrupole effects in solids are discussed, compared with nuclear quadrupole coupling in gases, and correlated to some extent with molecular structure in the solid state. The iodine crystal affords a good example of intermolecular interactions in the solid state. In this crystal, nuclear quadrupole ef…
