Nucleação transiente e estacionária em dissilicato de lítio
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2018-05-29)
Glasses and supercooled liquids tend to crystallize below the melting temperature. Crystallization is a phase transformation where the atomic structure ceases to be non-crystalline and becomes periodic. The focus of this ...
Pore condensation and freezing is responsible for ice formation below water saturation for porous particles
(National Academy of Sciences, 2019-04)
Ice nucleation in the atmosphere influences cloud properties, altering precipitation and the radiative balance, ultimately regulating Earth’s climate. An accepted ice nucleation pathway, known as deposition nucleation, ...
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(2015)
We studied the stochastic nature of heterogeneous nucleation of supercooled liquid water by molecular dynamics simulations. The systems were composed of 768 molecules; M of them had their positions restricted forming a ...
Nucleation and Inhibition Control during the Hydrothermal–Electrochemical Growth of Barium Titanate Films
(2000)
The control of the microstructure of BaTiO3 films grown on
titanium by the hydrothermal–electrochemical method was
investigated. Experiments were conducted in a three-electrode
high-pressure electrochemical cell in a ...
Crystal nucleation kinetics of a metastable phase on cordierite glass surfaces
(Soc Glass Technology, 1996-12-01)
The crystal nucleation rates of a metastable phase (chi) on the surface of a near stoichiometric cordierite glass were determined for temperatures between 839 and 910 degrees C (T-g similar to 800 degrees C). The surface ...

Crystal nucleation kinetics of a metastable phase on cordierite glass surfaces
(1996-12-01)
The crystal nucleation rates of a metastable phase (Χ) on the surface of a near stoichiometric cordierite glass were determined for temperatures between 839 and 910°C (Tg∼800°C). The surface nucleation kinetics of that ...
Particle Nucleation Using Different Initiators in the Miniemulsion Polymerization of Styrene
(Brazilian Society Of Chemical Engineering, 2015-01)
In miniemulsion polymerization, droplets nucleation is the key factor to ensure the production of polymer particles with a desired composition. The influence of the initiation on droplets nucleation is even conflicting and ...
Avaliação da anomalia da teoria de nucleação clássica em vidros silicatos
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEMCâmpus São Carlos, 2021-07-13)
Under some conditions, the Classical Nucleation Theory (CNT) provides a good description of the temperature dependence of the experimental homogeneous nucleation rates in supercooled liquids. Allegedly, however, it strongly ...
Phase nucleation in curved space
(Nature Publishing Group, 2015-04-21)
Nucleation and growth is the dominant relaxation mechanism driving first-order phase transitions. In two-dimensional flat systems, nucleation has been applied to a wide range of problems in physics, chemistry and biology. ...
