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 ...

Homogeneous nucleation process: Analytical approach
Physical Review B, 1993Homogeneous nucleation under isothermal conditions is modeled at the kinetic level. A Fokker-Planck-like equation with nonlinear coefficients that describes this process is solved analytically by a method based on boundary-layer theory combined with the Green's-function technique.

Homogeneous crystal nucleation in polymers
Journal of Physics: Condensed Matter, 2017The pathway of crystal nucleation significantly influences the structure and properties of semi-crystalline polymers. Crystal nucleation is normally heterogeneous at low supercooling, and homogeneous at high supercooling, of the polymer melt. Homogeneous nucleation in bulk polymers has been, so far, hardly accessible experimentally, and was even ...

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.

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.

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 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: reduction of binary nucleation to homomolecular nucleation
Journal of Aerosol Science, 1991Abstract Following the original ideas presented by Volmer, Flood, Neumann and Doring we have included the concept of an average virtual monomer on the thermodynamically consistent version of the classical theory for binary homogeneous nucleation.

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 ...
