Abstract

I will review our two main interests in ionic liquids, which are a class of interesting fluids that are composed out of mobile ions, like a molten salt, but at ambient temperatures. The first topic will deal with the construction of an accurate force-field that should be able to describe statics and dynamics of an ionic liquid at the all-atom scale [1-3]. To this end we are using ab-initio simulation data as input to reparametrize the partial charges. An interesting finding is, that the total ionic charge sums up to a value less than one. The second part of the talk deals with the study of the ionic double layer capacitance near an inert interface by using different coarse-grained representations of an IL.
