At Least 10-fold Higher Lubricity of Molecularly Thin D2O vs H2O Films at Single-Layer Graphene−Mica Interfaces

Lin, Hu; Habibova, Lala; Rauf, Abdul; González, José D. Cojal; Severin, Nikolai; Kirstein, Stefan; Sokolov, Igor; Rabe, Jürgen P.

Interfacial water is a widespread lubricant down to the nanometer scale. We investigate the lubricities of molecularly thin H2O and D2O films confined between mica and graphene, via the relaxation of initially applied ...

Atomic resolution with high-eigenmode tapping mode atomic force microscopy

Severin, Nikolai; Dzhanoev, A. R.; Lin, Hu; Rauf, A.; Kirstein, Stefan; Palma, Carlos-Andres; Sokolov, Igor; Rabe, Jürgen P.

Atomic surface structure imaging is instrumental for the understanding of surface-related phenomena. Here, we show that conventional tapping mode atomic force microscopy with high cantilever eigenmodes and subnanometer ...

Individual tubular J-aggregates stabilized and stiffened by silica encapsulation

Herman, Katherine; Kirmse, Holm; Eljarrat, Alberto; Koch, Christoph; Kirstein, Stefan; Rabe, Jürgen P.

Amphiphilic cyanine dyes in aqueous solution self-assemble into J-aggregates with diverse structures. In particular, the dye 3,3′-bis(3-sulfopropyl)-5,5′,6,6′-tetrachloro-1,1′-dioctylbenzimida-carbo-cyanine (C8S3) forms ...
