Single-site approximation for reaction-diffusion processes
We consider the branching and annihilating random walk A → 2A and 2A → 0 with reaction rates σ and λ, respectively, and hopping rate D, and study the phase diagram in the (λ/D, σ/D) plane. According to standard mean-field theory, this system is in an active state for all σ/D > 0, and perturbative renormalization suggests that this mean-field result is valid for d > 2; however, nonperturbative r...
متن کاملAnalytical approximation for reaction-diffusion processes in rough pores
– The concept of an active zone in Laplacian transport is used to obtain an analytical approximation for the reactive effectiveness of a pore with an arbitrary rough geometry. We show that this approximation is in very good agreement with direct numerical simulations performed over a wide range of diffusion-reaction conditions (i.e., with or without screening effects). In particular, we find th...

متن کاملSingle walled carbon nanotube in the reaction layer of gas diffusion electrode for oxygen reduction reaction
In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...
متن کاملFlexible single molecule simulation of reaction-diffusion processes
An algorithm is developed for simulation of the motion and reactions of single molecules at a microscopic level. The molecules diffuse in a solvent and react with each other or a polymer and molecules can dissociate. Such simulations are of interest e.g. in molecular biology. The algorithm is similar to the Green’s function reaction dynamics (GFRD) algorithm by van Zon and ten Wolde where longe...
