In this study, linearized transport pore model (LTPM) is applied for modeling nanofiltration (NF) membrane separation process. This modeling approach is based on the modified extended Nernst-Planck equation enhanced by Debye-Huckel theory to take into account the variations of activity coefficient especially at high salt concentrations. Rejection of single-salt (NaCl) electrolyte is inve...

We discuss charge density wave transport as the periodic flow of a quantum fluid electron–phonon correlates, viewed solitons, within condensate. Pair creation charged soliton droplets is prevented by their electrostatic energy below Coulomb-blockade threshold electric field. Above threshold, flows in drip-like fashion microscopic entities tunnel coherently from one charging macrostate to next. ...
