Self-assembled films from WO(3): Electrochromism and lithium ion diffusion
(ELSEVIER SCIENCE INC, 2010)
WO(3)/chitosan and WO(3)/chitosan/poly(ethylene oxide) (PEO) films were prepared by the layer-by-layer method. The presence of chitosan enabled PEO to be carried into the self-assembled structure, contributing to an increase ...
Diffusion in thorium carbide: A first-principles study
(Elsevier Science, 2015-12)
The prediction of the behavior of Th compounds under irradiation is an important issue for the upcoming Generation-IV nuclear reactors. The study of self-diffusion and hetero-diffusion is a central key to fulfill this goal. ...
Modeling water uptake in a cereal grain during soaking
(Elsevier, 2010-03)
A diffusion equation to describe the isothermal absorption of liquid water in a spherical solid that undergoes uniform swelling was derived. The resulting partial differential equation was solved using a finite difference ...
A full-atom multiscale modelling for sodium chloride diffusion in anion exchange membranes
(Elsevier Science, 2021-11)
A novel full-atom multiscale method, combining different computational approaches and aimed to describe diffusion of multiple ions in anion exchange membranes (AEM), is presented. The method is used to evaluate diffusion ...
Mechanisms and dynamics of crystal growth, viscous flow, and self-diffusion in silica glass
(2006)
We analyzed extensive literature data on crystal growth rate and viscosity in the temperature range between 1.1 T-g (glass transition temperature) and the melting point of silica, T-m. We selected data for one silica glass ...
A Symbiotic Self-cross Diffusion Model
(Khayyam Publishing, 2014)
Effect of Hydrodynamic Interactions on Self-Diffusion of Quasi-Two-Dimensional Colloidal Hard Spheres
(2015)
We compare experimental results from a quasi-two-dimensional colloidal hard sphere fluid to a Monte Carlo simulation of hard disks with small particle displacements. The experimental short-time self-diffusion coefficient ...
Diffusion calculations with two atomic models in h.c.p Zr-Nb diluted alloys
(Elsevier Science Sa, 2017-08)
In this work we perform a comparison of atomic diffusion multi-frequency models for h.c.p. lattices. Specifically, in diluted h.c.p. αZr-Nb alloy, we calculate, the tracer self- and impurity diffusion coefficients, with ...
Determinación del coeficiente de auto-difusión superficial del hielo ihDetermination of the superficial self-diffusion coefficient in ih-ice
(Asociación Física Argentina, 2019-04)
En este trabajo se estudió la evolución del ancho del surco formado por la intersección del borde de grano (BG) en una muestra de hielo bicristalina con la superficie libre de la misma. La muestra de hielo estudiada tenía ...
