界面处的可极化离子

Polarizable ions at interfaces

Yan Levin

摘要:

本文提出了一种非微扰理论,可以计算水-汽界面和水-油界面附近可极化离子的溶剂化自由能。理论预测较大的卤素阴离子吸附在界面上,而碱金属阳离子被排斥。理论计算的密度分布与使用极化力场的分子动力学模拟获得的密度分布相似。

英文摘要:

A non-perturbative theory is presented which allows to calculate the solvation free energy of polarizable ions near a water-vapor and water-oil interfaces. The theory predicts that larger halogen anions are adsorbed at the interface, while the alkali metal cations are repelled from it. The density profiles calculated theoretically are similar to those obtained using the molecular dynamics simulations with polarizable force fields.
