带电大分子的非线性屏蔽

Nonlinear screening of charged macromolecules

Gabriel Tellez

摘要:

我们提出了几个方面的电解质中的带电大分子的筛选。在回顾了基于线性Debye-Huckel理论的基本平均场方法之后,我们考虑了高电荷大分子的情况,其中线性近似被打破,系统由完全非线性Poisson-Boltzmann方程描述。这个非线性方程的一些分析结果给出了一些有趣的物理现象,如电荷重整化和曼宁凝聚。

英文摘要:

We present several aspects of the screening of charged macromolecules in an electrolyte. After a review of the basic mean field approach, based on the linear Debye-Huckel theory, we consider the case of highly charged macromolecules, where the linear approximation breaks down and the system is described by full nonlinear Poisson-Boltzmann equation. Some analytical results for this nonlinear equation give some interesting insight on physical phenomena like the charge renormalization and the Manning counterion condensation.
