Homogeneous ice nucleation in adsorbed water films: a theoretical approach [PDF]

open access: yesAtmospheric Chemistry and Physics
Ice nucleation plays a critical role in cloud formation and atmospheric processes, influencing precipitation and climate. In this study, we present a theoretical approach for describing homogeneous ice nucleation within adsorbed water films on insoluble ...

A Model of Liquid-phase Homogeneous Nucleation in a System Containing Seed Particles [Translated]†

open access: yesKONA Powder and Particle Journal, 2014
This paper deals with particle formation by homogeneous nucleation in a system containing seed particles. A model of homogeneous nucleation previously developed by the present authors (Kousaka and Nomura, 1997) is ...

A Novel 2D Model for Freezing Phase Change Simulation during Cryogenic Fracturing Considering Nucleation Characteristics

open access: yesApplied Sciences, 2020
A 2D computational fluid dynamics (CFD) model in consideration of nucleation characteristics (homogeneous/heterogeneous nucleation) using the volume of fluid (VOF) method and Lee model was proposed.

Homogeneous nucleation of silicon

open access: yesJournal of Aerosol Science, 1994
Abstract The homogeneous nucleation of silicon from the SiHCl system was studied theoretically for a wide range of compositions and temperatures. Contour plots of the conversion ratio and the chemical potential to nucleate are displayed. Nucleation rates were calculated using a modified classical nucleation model (Girshick et al. (1990) Aerosol Sci.

The Region of Validity of Homogeneous Nucleation Theory [PDF]

open access: yes, 1999
We examine the region of validity of Langer's picture of homogeneous nucleation. Our approach is based on a coarse-grained free energy that incorporates the effect of fluctuations with momenta above a scale k.

Homogeneous vs. heterogeneous nucleation in water-dicarboxylic acid systems [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
Binary heterogeneous nucleation of water-succinic/glutaric/malonic/adipic acid on nanometer-sized particles is investigated within the frame of classical heterogeneous nucleation theory. Homogeneous nucleation is also included for comparison. It is found

Homogeneous versus Heterogeneous Zeolite Nucleation [PDF]

open access: yesAngewandte Chemie International Edition in English, 1995
Aggregates of fractal dimension were found in the intermediate gel phases that organize prior to nucleation and crystallization (shown right) of silicalite from a homogeneous reaction mixture. Small- and wide-angle X-ray scattering studies prove that for zeolites nucleation may be homogeneous or heterogeneous.

Microscopic Mechanism and Kinetics of Ice Formation at Complex Interfaces: Zooming in on Kaolinite [PDF]

open access: yes, 2016
Most ice in nature forms thanks to impurities which boost the exceedingly low nucleation rate of pure supercooled water. However, the microscopic details of ice nucleation on these substances remain largely unknown.

Effect of cluster scavenging on homogeneous nucleation [PDF]

open access: yes, 1990
A closed‐form expression for the effect of cluster scavenging on the rate of homogeneous nucleation of a vapor in the presence of continuum regime particles is obtained by solving the kinetic equation of nucleation by the method of singular perturbation.
