Nucleation temperature

This work aims to investigate the mechanism of Pd nucleation and growth onto glassy carbon electrode from ChCl/urea/palladium mixture at room temperature using cyclic voltammetry (CV) and chronoamperometry (CA) techniques. Furthermore, X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy were used to examine the crystalline structure, morphology and compositions of deposited Pd samples.

This paper presents a methodology for studying nucleation and growth mechanisms of metals onto a glassy carbon electrode in a deep eutectic solvent (DES), a mixture of choline chloride and urea at a molar ratio of 1:2. Characteristics and composition of Co(II) complexes formed with the DES were evaluated by means of UV-vis measurements, which confirmed the good stability of these species at room temperature.

Phase formation upon hydrothermal crystallization of sodium titanosilicates has been studied in detail. It was shown that an excessive amount of Na and Si with respect to Ti affects the crystallization. It demonstrates that in a clear starting solution, high crystalline microporous titanosilicate (CST, Na2Ti2SiO7⋅2H2O) with sitinakite structure can be formed in 6 h and the crystallization is controlled by nucleation

The bubble nucleation in the framework of 3-3-1-1 model is studied. Previous studies show that first order electroweak phase transition occurs in two periods. In this paper we evaluate the bubble nucleation temperature throughout the parameter space. Using the stringent condition for bubble nucleation formation we find that in the first period, symmetry breaking from SU(3) → SU(2), the bubble is formed at the nucleation temperature T = 150 GeV and the lower bound of the scalar mass is 600 GeV.

The FeB nanoparticle (NP) consisting of 5000 particles (4500 Fe atoms and 500 B atoms) has been investigated by means of molecular dynamics (MD) simulation. When the amorphous FeB nanoparticle is annealed at temperature of 900 K for a long time, it is crystallized into bcc crystalline structure. The simulation shows that the sample undergoes crystallization via the nucleation mechanism.
