    In recent years, the introduction of large momentum transfer beam splitters to matter-wave interference experiments led to an increase in the sensitivity of a given interferometric measurement [1,2]. For nanomechanical gratings this corresponds to a reduction of the grating period. However, the stability and fabrication precision of those gratings limit the minimal grating period possible. To...

    Poster

    Palladium is an ideal model system to study hydrogen absorption in metals due to its extreme affinity to hydrogen, high solubility up to H/Pd = 1 atomic ratio, fast hydrogen absorption and desorption at room temperature and simple phase diagram. Pd nanoparticles can be used in catalysis and assist in hydrogen delivery into other materials for hydrogen storage through a spill-over process....

    Carbon has been well known as a compelling material to compete with silicon in the field of microchips.
    One promising method to fabricate micro- or nanoscale carbon architectures is to pyrolyze a pre-
    patterned polymer precursor [1]. Pyrolysis is, therefore, a crucial processing parameter. However, a
    mechanistic understanding of the pyrolysis process for sub-micrometer polymer geometries is...

  4. 168. Structure and reactivity of negatively charged platinum and palladium clusters
    Prof. Karin Fink (Karlsruher Institut für Technologie)

    Physics talks
    Talk

    Small Pt- and Pd-clusters play an important role as active sites in heterogeneous catalysis. For this reason, we are interested in their gas phase structure. Here we show the results of a joined experimental and theoretical study. Experimentally, structural information is obtained in the group of Schooss by trapped ion electron diffraction (TIED). The resulting scattering function is compared...
