Abstract

original image

Not thick-skinned: The solvation of a metallic nanoparticle in the ionic liquid [C4C1im][Ntf2] was investigated by molecular simulation with a specific interaction potential. The interfacial layer of ionic liquid is only one ion thick, and thus excludes a stabilization mechanism based on an electrostatic double layer.
