Describing diffusion, reaction and convection on porous medium
P. C. T. D'Ajello, L. Lauck, G. L. Nunes
In this paper we present a mathematical model for the electrochemical deposition aimed at the production of inverse opals. The real system consists of an arrangement of sub microme…
About diffusion in porous medium: the role of the correlation length
P. C. T. DÁjello, G. L. Nunes, J. J. Piacentini +1
In this paper we develop a model to describe the diffusion process in a porous medium. For the observed decrease in current yield, we propose other causes than difference in diffus…
Can a cylindrical geometry describe reaction-driven diffusion in nanometric porous media?
P. C. T. DAjello, M. L. Sartorelli, M. C. Ribeiro +1
We present a theoretical model describing the current transient behavior observed during electrodeposition in an opal modified electrode. As a basic unit we consider a cylindrical…
Can a cylindrical geometry describe diffusion in a nanometric porous media?
P. C. T. DÁjello, M. L. Sartorelli, L. Lauck
In a recent paper [1] we developed a theoretical model to describe current transients arising during electrochemical deposition experiments performed at the bottom of sub-micrometr…
