Igniting homogeneous nucleation [PDF]

open access: yesPhysical Review E, 2005
Transient homogeneous nucleation is studied in the limit of large critical sizes. Starting from pure monomers, three eras of transient nucleation are characterized in the classic Becker-D ring kinetic equations with two different models of discrete diffusivity: the classic Turnbull-Fisher formula and an expression describing thermally driven growth of

Nonisothermal homogeneous nucleation [PDF]

open access: yesThe Journal of Chemical Physics, 1992
Classical homogeneous nucleation theory is extended to nonisothermal conditions through simultaneous cluster mass and energy balances. The transient nucleation of water vapor following a sudden increase in saturation ratio is studied by numerically solving the coupled mass and energy balance equations.

Homogeneous nucleation of dislocations [PDF]

open access: yesPhysics of the Solid State, 2011
The mechanism and stochastic properties of the homogeneous nucleation of dislocations have been studied. An approach has been proposed for determining the nucleation rate based on consideration of the lifetimes of a metastable state. Primary data have been obtained using the molecular dynamics method. The dependences of the nucleation rate on the shear

Temperature Dependence of Homogeneous Nucleation in Ice. [PDF]

open access: yesPhysical Review Letters, 2019
Ice nucleation is a process of great relevance in physics, chemistry, technology, and environmental sciences; much theoretical effort has been devoted to its understanding, but it still remains a topic of intense research.

Investigation of Effective Parameters on Self-Nucleation Phenomenon in Semi-Crystalline Polymers [PDF]

open access: yesBaspārish, 2022
The crystallinity of semi-crystalline polymers is affected by both nucleation and growth processes, and the nucleation phase controls the kinetics of crystallization. In general, there are two types of homogeneous and heterogeneous nucleation.

Forward flux sampling calculation of homogeneous nucleation rates from aqueous NaCl solutions. [PDF]

open access: yesJournal of Chemical Physics, 2017
We used molecular dynamics simulations and the path sampling technique known as forward flux sampling to study homogeneous nucleation of NaCl crystals from supersaturated aqueous solutions at 298 K and 1 bar. Nucleation rates were obtained for a range of

Size dependence of volume and surface nucleation rates for homogeneous freezing of supercooled water droplets [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
The relative roles of volume and surface nucleation were investigated for the homogeneous freezing of pure water droplets. Experiments were carried out in a cryogenic laminar aerosol flow tube using supercooled water aerosols with maximum volume ...

Molecular Dynamics Simulations on Effect of Surface Roughness of Amorphous Substrate on Nucleation in Liquid Al

open access: yesMetals, 2022
In this study, we used molecular dynamics (MD) simulations to investigate the atomic ordering in the liquid aluminum (Al) adjacent to the amorphous substrate with smooth and rough surfaces.
