A multiscale theory to determine thermodynamic properties of confined fluids
… detail into a continuum framework such as the Nernst- Planck equation. EQT is a simple and fast approach to predict inhomogeneous density and potential profiles of confined fluids. EQT potentials can be used to construct a grand potential functional for classical density functional theory …

Molecular understanding of osmosis and a multiscale framework to investigate confined fluid properties
… The semi-classical framework utilizes the Nernst-Planck equation coupled with a theoretical potential formulation to obtain the accurate concentration and potential profiles in a channel. The results obtained from the semi-classical framework are then compared with results obtained from MD …

Modeling Nanofiltration Separation Mechanisms in Covalent Organic Framework Membranes
… flow through pores, as described by the Extended Nernst-Planck equation. If membrane structural and chemical characteristics are well defined, the DSPM-DE can theoretically be used to identify solute rejection mechanisms, predict NF performance, and guide membrane design. However, the presence of …

Methods of remedial treatment for carbonation-induced corrosion of reinforced concrete
… inhibitor injection. A model based on the Nernst-Planck equation, taking account of dissociation equilibria and solubility products of the relevant species, and activity coefficient of molecules, yielded a reasonable agreement with the experimental data. In the application of this model to …

Modeling process dynamics in membrane-electrolyte-assemblies of chloralkali electrolyzers considering steric and hydration effects
… model consists of the generalized Poisson-Nernst-Planck equation system coupled with the momentum balance. By considering the appropriate boundary conditions and mechanical equilibrium assumption, the model is then reduced into a 1-D modeling problem consisting of the generalized …

Ionic separation in electrodialysis : analyses of boundary layer, cationic partitioning, and overlimiting current
… difficulty in solving the singularly perturbed Nernst-Planck-Poisson equations. The steady-state Nernst-Planck-Poisson equations were converted into the Painlevé equation of the second kind (P[subscript II] equation). The converted model domain is explicitly divided into the space charge and …
