An equilibrium theory of rigid sphere fluids is developed based on the properties a new distribution function G(r) which measures density molecules in contact with solute arbitrary size. A number exact relations describe rather fully functional form are derived. These both geometrical considerations and virial theorem. knowledge G(a) where diameter enables one to arrive at equation state. The resulting analytical expression up third coefficient gives fourth within 3% fifth, insofar as it...

Interactions among defects in germanium and silicon have been investigated. The solid solutions involved bear a strong resemblance to aqueous insofar as they represent media for chemical reactions. Such phenomena acid-base neutralization, complex ion formation, pairing, all take place. These phenomena, besides being of interest themselves, are useful studying the properties semiconductors which occur. following article is blend theory experiment, describes developments this field during past...

A mechanism for the donor formation during heat treatment of silicon crystals is presented which accounts quantitatively complex kinetic phenomena and consistent with known extra-kinetic information concerning this system. Atomically dissolved oxygen introduced growth crystal reacts, in course treatment, to form a sequence kinetically linked aggregates till finally polymeric silica (Si${\mathrm{O}}_{2}$) formed. Only those possess fewer than five bound atoms appear act intensively as donors...

Permeabilities for a series of gases through free-standing films the conjugated polymer polyaniline are reported.

By extending the ideas previously applied to statistical mechanical theory of hard sphere fluids Reiss, Frisch, and Lebowitz, an approximate expression has been determined for work creating a spherical cavity in real fluid. In turn knowledge this entity permits evaluation properties such as surface tension normal heats vaporization Henry's law constants fluid mixtures. The agreement between calculated experimental is satisfactory.

Recently, much interest has been focused upon the preparation of monodispersed colloids using ``growth by diffusion'' process. Although these are useful tools in experimental procedures, no well-established reason given to explain why method should produce such uniform dispersions. In this paper it is shown that an assembly competing particles, growing diffusion, develop squares their radii at equal rates. This condition provides a mechanism leading towards uniformity. A method, based on...

The mutual absorption of two nonparallel classical photon fields through the production electron pairs is calculated. One treated accurately in sense that wave functions are employed which solutions Dirac equation containing potential this field Hamiltonian. second introduced as a first-order perturbation to system first field.

A detailed examination of the translation–rotation paradox in theory nucleation is presented. An earlier conclusion, due to Reiss and Katz, that associated with neglect fluctuation center mass a liquid-drop nucleus reaffirmed. Transformations coordinates are performed quantitatively order demonstrate this fact. Furthermore, computed for lattice model. new factor not appearing classical appears, but it much smaller than introduced by Lothe Pound only becomes important large nuclei.

We have investigated homogeneous nucleation of water droplets in the vapor phase. Nucleation has been previously studied a number times using various experimental techniques. The pulse technique used here allows accurate measurements rates J vs supersaturation S range from 105 to 109 cm−3 s−1. advance reported consists fact that J–S curves are measured at selectable constant temperature. determined supersaturated mixed with carrier gases as functions and temperature...

Two types of polyelectrolyte multilayer films have been reported in the literature. These are (i) whose mass and thickness increase linearly as number deposited bilayers increases (ii) that grow exponentially. We present a model for buildup exponentially growing allows discussion behavior them unified manner. This is based on diffusion both out whole film part chains at least one polyelectrolytes constituting multilayer. In short, brought into contact with solution able to diffuse film....

The process by which liquid cloud droplets homogeneously crystallize into ice is still not well understood. nucleation based on the standard and classical theory of homogeneous freezing initiates within interior volume a droplet. Current experimental data rates in supercooled water, both air emulsion oil samples, show considerable scatter. For example, at -33 degrees C, reported volume-based water vary as many 5 orders magnitude, outside range measurement uncertainties. Here, we that nucleus...

It is shown that tunneling theories of ionization by lasers are subject to upper and lower bounds on the Keldysh parameter gamma. The limit, gamma-->0, applies quasistatic electric fields, but not laser fields. For lasers, gamma-->0 limit requires a relativistic treatment. Bounds applicability depend parameters other than gamma, confirming rule strong-field phenomena require more one dimensionless for scaling.
