Interactions between charged surfaces immersed in electrolyte solutions have been the subject of extensive study for decades, owing to their fundamental importance in numerous biological and industrial systems.

Introduction Click to copy section linkSection link copied! Using simple salt to regulate the stability of colloidal dispersions that contain charged particles is a well-established process, with a firm theoretical foundation. (1−5) Mean-field treatments of aqueous systems tend to be accurate at low and intermediate concentrations when the salts are composed of monovalent species.

An efficient method to establish electrostatic screening lengths of Restricted Primitive Model electrolytes We present a novel, and computationally cheap, way to estimate electrostatic screening lengths from simulations of Restricted Primitive Model (RPM) electrolytes. We demonstrate that the method is accurate by comparisons with simulated long-ranged parts of the charge density, at various Bjerrum lengths, salt concentrations and ion diameters.
