Numerical analysis of a model for nickel–iron alloy electrodeposition on rotating disk electrode

Abstract

To better understand the nickel-iron electrodeposition process, we have developed one-dimensional numerical model. This model addresses dissociation, diffusion, electromigration, convection and deposition of multiple ion species. The reaction mechanism in this model differs in that N i 2+ and F e 2+ are the electroactive species and N iOH + and F eOH + are not involved whatsover. To take account of the anisotropic behaviour of the solution we introduce a domain decomposition numerical method. Simulations with experimental data shows that our model can predict characteristic features of the nickel-iron system.

Criterion of positivity for semilinear problems with applications in biology

“…positivity properties to ensure physical reality. For instance, when considering the evolution of matter quantities, such as in biology (or also physics [1], chemistry [15],...), the positivity of the solutions of the underlying dynamical system is a crucial prerequisite to achieve the well-posedness of the problem and to guarantee its physical relevance.…”
