A self-consistent mode-coupling theory is presented for the viscosity of solutions of charged rodlike polymers. The static structure factor used in the theory is obtained from polymer integral equation theory; the Debye-Huckel approximation is inadequate even at low concentrations. The theory predicts a nonmonotonic dependence of the reduced excess viscosity eta(R) on concentration from the beh...

The thermodynamics of electrolyte solutions has been investigated by many scientists throughout the last century. While several theories have been presented, the most popular models for the electrostatic interactions are based on the Debye− Hückel and mean spherical approximation (MSA) theories. In this paper we investigate the differences between the Debye− Hückel and the MSA theories, and com...

Monte Carlo (MC) simulations have been performed for primitive model electrolytes for moderate Bjerrum parameters (B = 1, B = 1.546 and a few with B = 1.681) and values of m in t he range ca. 0.015-0.45. Emphasis has been laid on very dilute systems. Several millions of configurations have been used, and the number of ions in each simulation (N) was varied between N = 32 and N = 1000 (N = 1728 ...

In this work, an electrolyte-UNIQUAC model was developed by replacement of Boltzmann weight binary interaction parameters by the nonextensive Tsallis weight. A summation of the long-range electrostatic term (Debye-Huckel equation) and a short-range interaction term were considered in the calculation of thermodynamic properties. A framework proposed by Chen and co-workers was employed for the de...

The Debye-Huckel equation is solved for the electrostatic interaction of point charges on the surface of a dielectric cylinder immersed in salt water. Numerical results are given for the potential as a function of axial separation for charges on the same side and on opposite sides of the cylinder, and for two values of the Debye screening length: infinity and unity, in units of the cylinder rad...

Aims. We calculate the plasma environment effects on ionization potentials (IPs) and K-thresholds used in modeling of K lines for all ions belonging to isonuclear sequences abundant elements apart from oxygen iron, namely: carbon, silicon, calcium, chromium, nickel. These calculations are extend data points fits universal formulae, first proposed our fourth paper this series, predict IP K-thres...

We present a model capturing the important contributors to the effects of temperature on the observable electrophoretic mobilities of small ions, and on solution conductivity and pH. Our temperature model includes relations for temperature-dependent viscosity, ionic strength corrections, degree of ionization (pK), and ion solvation effects on mobility. We incorporate thermophysical data for wat...
