It is well known that the crystallization of liquids often initiates at interfaces to foreign solid surfaces. In this study, using polarized light optical microscopy, atomic force microscopy (AFM), and wide-angle X-ray scattering (WAXS), we investigate ...

Impact of formulations of the homogeneous nucleation rate on ice nucleation events in cirrus [PDF]
Homogeneous freezing of solution droplets is an important pathway of ice formation in the tropopause region. The nucleation rate can be parameterized as a function of water activity, based on empirical fits and some assumptions on the underlying ...

Homogeneous nucleation of silicon
Abstract The homogeneous nucleation of silicon from the SiHCl 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.

Ice nucleation from aqueous NaCl droplets with and without marine diatoms [PDF]
Ice formation in the atmosphere by homogeneous and heterogeneous nucleation is one of the least understood processes in cloud microphysics and climate. Here we describe our investigation of the marine environment as a potential source of atmospheric IN ...

Statistical Approach to Crystal Nucleation in Glass-Forming Liquids
In this work, methods of description of crystal nucleation by using the statistical approach are analyzed. Findings from classical nucleation theory (CNT) for the average time of formation of the first supercritical nucleus are linked with experimental ...

Imaging the homogeneous nucleation during the melting of superheated colloidal crystals [PDF]
The nucleation process is crucial to many phase transitions, but its kinetics are difficult to predict and measure. We superheated and melted the interior of thermal-sensitive colloidal crystals and investigated by means of video microscopy the ...

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