The Thermodynamics of High-Polymer Solutions: I. The Free Energy of Mixing of Solvents and Polymers of Heterogeneous Distribution

The theories of Flory and Huggins for the free energy of mixing of a homogeneous chain polymer of uniform molecular weight with a single uniform solvent have been extended to the case of a polymer mixture of varying chain lengths with a mixture of solvents....

Magnitude determination for deep-focus earthquakes

The magnitude of deep-focus earthquakes is so defined as to make the energy released in two shocks of the same magnitude equal, regardless of focal depth.—Charts are given which, in connection with the equations for the magnitude of shallow shocks,...

Transmission, Reflection, and Guiding of an Exponential Pulse by a Steel Plate in Water. I. Theory

The problem of the action of an underwater explosion—a pulse of the form p max e −t/τ—on an elastic plate in water can be divided into two parts. In the first, the plate is considered as an infinite slab with the explosionwave as an incident plane...

On the intensities and the multipole character in the spectra of the rare earth ions

AN INVESTIGATION OF THE FREE OSCILLATIONS OF A SIMPLE CURRENT SYSTEM

Any sudden local addition of momentum to a rotating fluid body will generally result in some type of oscillation of that body. In the case of the ocean, this oscillation will include the form of “long” or “tidal” waves. A previous investigation...

Molecular Theory of the Scattering of Light in Fluids

A molecular theory of the scattering of light by fluids of isotropic molecules is developed, utilizing recent advances in the statistical mechanics of condensed phases. The results are shown to be the same in first approximation as those of the continuous...

The genesis of twin crystals

Interest has recently been indicated in a possible cause for the occurrence of twins. Apparently the only popular approach to twinning has been through the empirical rules of twinning enunciated by the French School. The writer's views, now some twenty...

ON THE PROPAGATION OF FREQUENCIES AND ENERGY IN CERTAIN TYPES OF OCEANIC AND ATMOSPHERIC WAVES

In this paper the energy and frequency propagation in certain types of plane waves in the atmosphere and in the ocean are investigated, these wave trains being characterized by the property that frequency and wave number are slowly varying functions of...

Free Volume and Entropy in Condensed Systems II. Entropy of Vaporization in Liquids and the Pictorial Theory of the Liquid State

The results of the first paper of this series, and a generalization of a method due to Eyring, are used to obtain an expression for the free volume of a liquid, V f =fb 3 g 3 /h 3 n 3 ×[RT/ΔE v ] 3 , and an equation for the entropy of vaporization....

The Thermodynamics of High‐Polymer Solutions: II. The Solubility and Fractionation of a Polymer of Heterogeneous Distribution

The free energy relations for heterogeneous molecular weight distributions developed in Part I, are applied to problems of solubility and fractionation. Critical conditions for solubility are obtained. A rigorous expression for the solubility is derived,...

The Influence of Molecular Flexibility on the Intrinsic Viscosity, Sedimentation, and Diffusion of High Polymers

Expressions for the mean square separation of chain ends and modifications of the formula for an ideal coil are discussed. On the basis of these and of the hydrodynamic theory of intrinsic viscosity, an interpretation of the modified Staudinger rule is...
