Homogeneous Ice Nucleation Under Shear

The Journal of Physical Chemistry B, 2020
Homogeneous ice nucleation involving a water flow is subject to shear, which may greatly affect the ice nucleation rate. In this work, we investigate the homogeneous ice nucleation rate under shear through molecular dynamics simulations. It is found that the ice nucleation rate changes nonlinearly with varying shear rates and reaches a maximum at an ...

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.

Homogeneous nucleation rates for water

The Journal of Chemical Physics, 1993
We 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, 1993
Homogeneous 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.

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.

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.

Homogeneous crystallization and buried interface passivation for perovskite tandem solar modules

Science
Scalable fabrication of all-perovskite tandem solar cells is challenging because the narrow-bandgap subcells made of mixed lead-tin (Pb-Sn) perovskite films suffer from nonuniform crystallization and inferior buried perovskite interfaces.

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 ...

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: reduction of binary nucleation to homomolecular nucleation

Journal of Aerosol Science, 1991
Abstract 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.
