Nanoporous membranes ion transport noise dynamics: Experiments match Simulations

POSTER

Abstract

Noise in nanoporous membranes and 2D based graphene nanoporous membranes is a ubiquitous phonomenon that is experimentally and theory model dynamics match is established for the first time. The theory is formulated step by step from Poisson-Nernst-Planck-Navier-Stokes model and Langevin dynamics model and matched to the time scales of experiments with the new theory dynamical model for the first time. The theory matched to the time scales for both regions of low frequency 1/f noise and high frequency noise frequencies. The results for both thick nanoporous membranes and ultrathin 2D graphene based nanoporous membranes were obtained by connecting the nanoporous membrane across bulk reservoirs of dimensions greater than few centimeters. The work makes significant leap establish of applications of nanoporous membranes in water desalination, DNA sequencing, bio-applications, ionic separation and power generator renewable energy applications.
