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 ...
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 ...
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, ...
Crystallization of sunflower oil waxes
(Springer, 2003)
Experimental investigation of wall nucleation characteristics in flow boiling
(American Society of Mechanical Engineers, 2015-05)
Wall nucleation experiments have been performed in a vertical annulus test section for investigation of the bubble departure diameter and bubble departure frequency. The experimental data in forced convective subcooled ...
Computational investigation of structure, dynamics and nucleation kinetics of a family of modified Stillinger-Weber model fluids in bulk and free-standing thin films
(Royal Society of Chemistry, 2016-01)
In recent years, computer simulations have found increasingly widespread use as powerful tools for studying phase transitions in wide variety of systems. In the particular and very important case of aqueous systems, the ...
Nucleation and growth in two dimensions
(John Wiley & Sons Inc, 2019-10-22)
We consider a dynamical process on a graph G, in which vertices are infected (randomly) at a rate which depends on the number of their neighbors that are already infected. This model includes bootstrap percolation and ...
Mechanisms of Nucleation and Stationary States of Electrochemically Generated Nanobubbles
(American Chemical Society, 2019-07)
Gas evolving reactions are ubiquitous in the operation of electrochemical devices. Recent studies of individual gas bubbles on nanoelectrodes have resulted in unprecedented control and insights on their formation. The ...
Electrochemical formation of copper phosphide from aqueous solutions of Cu(II) and hypophosphite ions
(Pergamon-Elsevier Science Ltd, 2020-09-10)
The electrochemical formation of copper phosphide phases on vitreous carbon electrodes from Cu(II) and hypophosphite acid aqueous solutions has been studied. It was found that the main component in the deposits was Cu, ...
