Debye Annual Lecture by Prof. M. Bonn

Abstract:

Water interfaces differ from the bulk, in both their physical structure and chemical composition. A particularly fascinating interface is the water-graphene interface. Water has been reported to flow through carbon nanotubes (essentially curved graphene) with remarkably low resistance. Large-area graphene can serve as an electrochemical electrode, allowing detailed studies of electrochemical processes.

Surface-specific spectroscopy on water in contact with graphene enables elucidating electrochemistry at the molecular level [1,2], investigating the origin of the friction between water as it flows along graphene [3], and allows to unequivocally define at what thickness water is truly confined [4].
