概 要

   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 enable elucidating electrochemistry at the molecular level [1,2], and investigating the origin of the friction between water as it flows along graphene [3].
