Simulación con el método de dinámica molecular de los procesos de nucleación y crecimiento de las nanopartículas de Ag a partir de la fase gaseosa
(Lima (Perú)PE, 2008-11)
El método de Dinámica Molecular fue aplicado al estudio de la nucleación y crecimiento de los clusters de Ag a partir de la fase gaseosa. Mediante el uso del potencial de interacción Tight-Binding SMA se estudia las ...
Bubble wall correlations in cosmological phase transitions
(American Physical Society, 2020-11-12)
We study statistical relationships between bubble walls in cosmological first-order phase transitions. We consider the conditional and joint probabilities for different points on the walls to remain uncollided at given ...
Physicochemical aspects of epoxide driven nano-ZrO2 hydrogel formation: Milder kinetics for better properties
(Royal Society of Chemistry, 2016-03)
Robust and highly transparent quasi amorphous ZrO2-water-glycerol hydrogels were obtained in a mild one pot procedure, based on the 2,3-epoxy-1-propanol driven alkalinization. SAXS-based characterization of the sol-gel ...
Metastable eutectoid transformation in spheroidal graphite cast iron: Modeling and validation
(Multidisciplinary Digital Publishing Institute, 2018-07)
This paper presents a new microstructural model of the metastable eutectoid transformation in spheroidal graphite cast irons. The model takes into account the nucleation and growth of pearlite nodules. The nucleation is ...
Aplicabilidad de modelos matemáticos para simular la nucleación de partículas de grafito en fundición esferoidal de pequeños espesores
(Universidade Federal do Rio de Janeiro, 2003-12)
El estudio detallado de la potencial aplicación de la fundición esferoidal en la fabricación de piezas de espesores inferiores a 6 mm es muy reciente. La información con que se cuenta en la actualidad es escasa, contrariamente ...
Influence of Gold Nanoparticles on the Kinetics of α-Synuclein Aggregation
(American Chemical Society, 2013-11)
α-synuclein (AS) is a small (140 amino acids), abundant presynaptic protein, which lacks a unique secondary structure in aqueous solution. Amyloid aggregates of AS in dopaminergic neurons of the midbrain are the hallmark ...
Homogeneous precipitation of layered Ni(II)–Cr(III) double hydroxides
(Academic Press Inc Elsevier Science, 2007-05)
An adequate account of the hydrolytic properties of Cr3+ and Ni2+ allows setting the conditions for homogeneous nucleation of layered Ni(II)–Cr(III) double hydroxides; water exchange and hydrolysis rate constants indicate ...
Uniaxial-deformation behavior of ice Ih as described by the TIP4P/Ice and mW water models
(American Institute of Physics, 2018-10)
Using molecular dynamics simulations, we assess the uniaxial deformation response of ice Ih as described by two popular water models, namely, the all-atom TIP4P/Ice potential and the coarse-grained mW model. In particular, ...
Reaction-induced phase separation in an epoxy/low molecular weight solvent system
(Springer, 2003-07)
Blends based on a stoichiometric mixture of diglycidyl ether of bisphenol A (DGEBA) and 2,2′-bis(4-amino-cyclohexyl)methane (ACHM) and cyclohexane as low molecular weight solvent were studied. The polymerization kinetics ...
Computational simulation of microstructure evolution during solidification of ductile cast iron
(Maney Publishing, 2008-12)
This paper presents a thermomicrostructural model for the simulation of the solidification process of an eutectic ductile cast iron. The thermal balance is written at a macroscopic level and takes into account both the ...
