In this paper, we study the well-posedness of Poisson–Nernst–Planck system with no-flux boundary condition and singular permanent charges in two dimension. The main difficulty comes from the lack of integrability of singular permanent charges. In order to overcome the difficulty, the main idea is to transform the system into another weighted parabolic system. By choosing suitable weighted spaces, local existence of solutions can be obtained based on a fixed-point argument. Moreover, we also… 


Global existence of the non-isothermal Poisson–Nernst–Planck–Fourier system
In this paper, we consider a non-isothermal electrokinetic model, which is derived from the Energetic Variational Approach. The charge transport is described through the Poisson-Nernst-Planck
Exponential Decay Estimates for the Stability of Boundary Layer Solutions to Poisson-Nernst-Planck Systems: One Spatial Dimension Case
The main idea of the argument is to transform the perturbed problem into another parabolic system with a new and useful energy law for the proof of the exponential decay estimate.
A Generalized Poisson-Nernst-Planck-Navier-Stokes Model on the Fluid with the Crowded Charged Particles: Derivation and Its Well-Posedness
A general method is developed to show that the cross-diffusion system is globally asymptotically stable under small perturbations around a constant equilibrium state and to obtain the optimal decay rates of the solution and its derivatives of any order.

We consider ionic electrodiffusion in fluids, described by the Nernst–Planck–Navier–Stokes system in bounded domains, in two dimensions, with Dirichlet boundary conditions for the Navier–Stokes and
Analysis of the Poisson–Nernst–Planck equation in a ball for modeling the Voltage–Current relation in neurobiological microdomains
Abstract The electro-diffusion of ions is often described by the Poisson–Nernst–Planck (PNP) equations, which couple nonlinearly the charge concentration and the electric potential. This model is
Transport of Charged Particles: Entropy Production and Maximum Dissipation Principle
In order to describe the dynamics of crowded ions (charged particles), we use an energetic variation approach to derive a modified Poisson-Nernst-Planck (PNP) system which includes an extra
