講演題目: Solvation of Nanoions in Water
要旨:
Theoretical models of ion effects have a long tradition in theoretical Physical Chemistry, where force-field based MD simulations are widely used. For small ions, for example from the alkali metal or halide groups, some key principles have been understood like the concepts of strong vs. weak hydration or the ordering of these ions in the Hofmeister series.
In recent years a new class of ions has been the topic of interest: ions that are much larger in size and are at the same time multiply charged. These “nanoions” have special properties in the way they bind to interfaces and solutes. For this class of ions, the theoretical understanding is much less developed.
In this talk, we will present MD simulations of with atomistic models and with a simple nanometer sized Kihara model. The simple Kihara model is able to reproduce several of the key effects that are observed for nanoions. The implications for a classification scheme of nanoions similar to the Hofmeister scale will be discussed.
