Diffusion of charged fluids in charged porous matrices

The diffusion of charged fluids in charged porous matrices was studied. The extensive simulations of ionic fluids in a charged porous matrix were performed to understand diffusion in disordered matrices. Simulations were performed using the molecular dynamics method where the electrostatic interactions were handled using the Ewald summation. It was found that in the fluid, the particles were influenced not only by the matrix particles but also by the other fluid particles which were captured in the traps, slowing their motion and reducing the diffusion.
