WebThe reflection coefficient was originally introduced by Staverman to describe the movement of nonelectrolytes through membranes. When this coefficient is extended to salts, one … WebTransmission Lines: Reflection Coefficient and VSWR. We are now aware of the characteristic impedance of a transmission line, and that the tx line gives rise to forward and backward travelling voltage and current waves. We will use this information to determine the voltage reflection coefficient, which relates the amplitude of the forward ...
WebJun 6, 2012 · In this case, the osmotic reflection coefficient is a function of a/r c, the ratio of the solute-to-pore radius. When electrostatic interactions between the solute and pore charge are present, the osmotic reflection coefficient also depends on the electric charge densities and ion strengths. WebJun 1, 1972 · Chem., 37 (1972) 240 A.J. STAVERMAN Since we have 3 components, the solvent 0, the positive ion 1 and the negative ion 2, we have 6 friction coefficients roa, roz,fom, rlz,Jlm and f2,,. These must be derived from 6 …
WebFor example, Staverman's coefficient is equal to zero when the solute can diffuse through the membrane as easily as through pure solvent (no membrane resistance), κ α D α = D 0 …
