How Wrong is the Debye-Huckel Approximation for Dilute Primitive Model Electrolytes with Moderate Bjerrum Parameter?
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 ...
متن کاملComparison of the Debye–Huckel and the Mean Spherical Approximation Theories for Electrolyte Solutions
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...
متن کاملپتانسیل الکتروستاتیک یک مولکول زیستی مارپیچی در رژیم دیبای- هوکل با در نظر گرفتن ناهمگنی دی‌الکتریک
Inside living cells, many essential processes involve deformations of charged helical molecules and the interactions between them. Actin filaments and DNA molecules are important examples of charged helical molecules. In this paper, we consider an impermeable double stranded charged molecule in the solvent. According to the nature, the dielectric constant of the molecule is considerably differe...
متن کاملImage Methods for Electrostatic Potentials
Image method is a classical method for finding electrostatic potentials in dielectric or conducting objects with special geometries. The image method provides simple and analytical formulas to represent the reaction field on a charge in an object as a result of the polarization effect from the surrounding material. In this paper, we will provide an overview of the classical results of image met...
متن کاملMolecular electrostatic potentials of DNA base-base pairing and mispairing.
An understanding of why adenine (A) pairs with thymine (T) and cytosine (C) with guanine (G) in DNA is very useful in the design of sensors and other related devices. We report the use of dissociation energies, geometries and molecular electrostatic potentials (MEPs) to justify the canonical (AT and CG) Watson-Crick pairs. We also analyze all mismatches in both configurations-cis and trans-with...
