Heterogeneous nucleation or homogeneous nucleation?

The Journal of Chemical Physics, 2000
The generic heterogeneous effect of foreign particles on three dimensional nucleation was examined both theoretically and experimentally. It shows that the nucleation observed under normal conditions includes a sequence of progressive heterogeneous processes, characterized by different interfacial correlation function f(m,x)s.

Homogeneous nucleation of magnesium hydroxide

Talanta, 1967
The rate of homogeneous nucleation of magnesium hydroxide has been determined as a function of solution concentration, using a quasi-homogeneous precipitation technique and electronic particle counting. The nucleation rate becomes measurable at super-saturations of about 4, and is dependent on the 33rd power of the product aMgaOH(2).

Homogeneous nucleation of calcium hydroxide

Talanta, 1968
The rate of nucleation of calcium hydroxide in carefully purified supersaturated solution was observed to be about 10(3) particles, cm(-3). sec(-1), in solutions with activity products a(ca)a(OH)(2) around 4 x 10(-5). These data correspond to a homogeneous nucleus containing about 55Ca(OH)(2) units, and a nucleus-solution interfacial tension of 65 erg ...

Gasdynamics and homogeneous nucleation

Advances in Colloid and Interface Science, 1977
Abstract : The fundamentals of gasdynamics of one-dimensional flows with condensation are reviewed paying special attention to concepts from nonequilibrium flows, honogeneous nucleation, droplet growth. Flow systems for experimental research in condensation, namely steady-flow Laval nozzles, Ludwieg tubes, shock tubes and high intensity supersonic ...

Homogeneous Nucleation in Condensation

1964
Abstract The current status of the theory of homogeneous nucleation in condensation is briefly reviewed. It is concluded that the present steady-state theory which correctly considers the statistical mechanical contributions to the free energy of formation of critical nuclei predicts rates that are higher by a factor of 10 18 than those of the ...

Homogeneous nucleation kinetics

Journal of Crystal Growth, 1983
Homogeneous nucleation kinetics are rederived in a manner fundamentally similar to the approach of classical nucleation theory with the following modifications and improvements. First, the cluster is a parent phase cluster and does not require energization to the parent state.

Binary homogeneous nucleation

2008
Binary homogeneous nucleation is the process by which two vapors can condense simultaneously to form a solution droplet. This process can be very efficient to remove appreciable amount of trace gases from the atmosphere through gas-to-particle conversion.

The homogeneous nucleation of nonane

2008
INTRODUCTION The first complete theory of homogeneous nucleation, known as the classical theory, was developed by Volmer and Weber [i], Farkas, and Becker and Doering. Classical theory treats a cluster of molecules as a droplet whose properties (e.g., surface tension, density) are the same as those of the liquid.

Nucleation in Homogeneous Vapors

1966
This is essentially a review of a longer, more rigorous paper by J. Feder, K.C. Russell, J. Lothe, and G.M. Pound [6]; those desiring a more complete discussion of the topics in this paper are referred to this work of Feder et al.
