Homogeneous nucleation rates for water
The Journal of Chemical Physics, 1993We have investigated homogeneous nucleation of water droplets in the vapor phase. Nucleation in water vapor has been previously studied a number of times using various experimental techniques. The nucleation pulse technique used here allows accurate measurements of homogeneous nucleation rates J vs supersaturation S in the range from 105 to 109 cm−3 s ...

Heterogeneous nucleation or homogeneous nucleation?
The Journal of Chemical Physics, 2000The 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, 1967The 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, 1968The 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 ...

Homogeneous Nucleation in Condensation
1964Abstract 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 ...

Gasdynamics and homogeneous nucleation
Advances in Colloid and Interface Science, 1977Abstract : 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 kinetics
Journal of Crystal Growth, 1983Homogeneous 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 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
The Journal of Chemical Physics, 1984The homogeneous nucleation rate of n-nonane has been measured as a function of temperature and supersaturation ratio in a precision fast-expansion chamber. The measured nucleation rate ranges from 102 to 105 drops/cm3 over the temperature range 215–270 K.

The homogeneous nucleation of nonane
2008INTRODUCTION 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.
