General theory of charge regulation within the Poisson-Boltzmann framework: Study of a sticky-charged wall model

This work introduces a sticky-charge wall model as a simple and intuitive representation of charge regulation. Implemented within the meanfield level of description, the model modifies the boundary conditions without affecting the underlying Poisson-Boltzmann (PB) equation of an electrolyte. Employing various modified PB equations, we are able to assess how various structural details of an electrolyte influence charge regulation. Published under license by AIP Publishing.
