Poisson–Nernst–Planck (PNP) models constitute a cornerstone in the mathematical description of ionic transport and electrostatic interactions in diverse physical and biological systems. These models ...
You probably recognise equation 1 as the Nernst equation. This equation defines the relation between the concentrations of an ion on either side of a membrane that it perfectly selective for that ion ...
