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 ...
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 ...
Vortices nucleation by inherent fluctuations in nematic liquid crystal cells
(Springer, 2022)
Multistable systems are characterized by exhibiting domain coexistence, where each domain accounts for the different equilibrium states. In case these systems are described by vectorial fields, domains can be connected ...
Electrodeposition of CdTe thin films onto n-Si(1 0 0): Nucleation and growth mechanisms
(2005)
The mechanisms related to the initial stages of the nucleation and growth of cadmium telluride (CdTe) thin films on the rough face side of a (1 0 0) monocrystalline n-type silicon have been studied as a function of different ...
Pd Nucleation and Growth Mechanism Deposited on Different Substrates
(Elsevier, 2015-08)
Palladium, has an unique property between the noble metals, that is the higher capacity to adsorb onto the surface, and within its network, the hydrogen, resulting the Pd of crucial importance to many industrial processes ...
Nucleation and growth of silver nanostructures onto HOPG electrodes in the presence of picolinic acid
(Elsevier Science, 2013-01)
Silver electrodeposition onto HOPG electrodes in the presence of picolinic acid (PA) has been studied by cyclic voltammetry and chronoamperometry. Changes in the nucleation and growth mechanisms, which are dependent on the ...
Nucleation and growth mechanisms of palladium, nanoflower-shaped, and its performance as electrocatalyst in the reduction of Cr(VI)
(Springer, 2019-08-24)
Palladium electrocrystallization on Ti film is studied through theoretical models of nucleation and growth. At the applied potential + 0.1 V, palladium electrodeposition followed a mechanism through these steps: adsorption, ...
Morphology and magnetic properties of FeCo alloy synthesized through polyol process
(Springer, 2020)
Equiatomic FeCo alloy was synthesized through polyol process and size reduction was attempted using heterogeneous nucleating agents such as Cu and Pt. The average particle size of FeCo reduced from 138 to 17 nm using ...
