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 ...
Bubble nucleation and growth in slow cosmological phase transitions
(Elsevier Science, 2018-03)
We study the dynamics of cosmological phase transitions in the case of small velocities of bubble walls, vw<0.1. We discuss the conditions in which this scenario arises in a physical model, and we compute the development ...
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 ...
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 ...
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 ...
Bubble nucleation and growth in very strong cosmological phase transitions
(Elsevier Science, 2017-06)
Strongly first-order phase transitions, i.e., those with a large order parameter, are characterized by a considerable supercooling and high velocities of phase transition fronts. A very strong phase transition may have ...
A statistical study of heterogeneous nucleation of ice by molecular dynamics
(Elsevier Science, 2015-07)
Abstract 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 ...
