    Transmission of Rotational Motion Between Molecule-Gears

    A molecule-gear rotating without a lateral jittering effect is constructed using a single copper adatom as a physical axle on a lead superconducting surface. The molecule-gear has a diameter of 1.2 nm with 6 t...

    A Simple Example of a Molecule-Gear Train: PF3 Molecules on a Cu(111) Surface

    A train of molecule gears consisting of PF3 molecules was studied using semi-empirical ASED+ method to explore the mechanism of rotational transmission along this train. It was observed that a unidirectional rota...

    Step-by-step rotation of a molecule-gear mounted on an atomic-scale axis

    Designing and building molecular machines at the nanometre scale is a conceptual and synthetic challenge. Rotation of a single molecule has been observed but controlling the direction of the rotation has so fa...

    Synthesis of graphite monolayer stripes on a stepped Ni(771) surface

    Graphite stripes on a stepped Ni(771) substrate were grown in situ by cracking propylene followed by annealing at optimal temperatures between 450 and 590° C. The samples were studied by means of C 1s and Ni 3p c...
