  • Coupled Pb chains on Si(557): Origin of one-dimensional conductance 
    Tegenkamp, Christoph; Ohta, T.; McChesney, J.L.; Dil, H.; Rotenberg, E.; Pfnür, Herbert; Horn, K. (College Park, MD : American Physical Society, 2008)
    The Pb/Si(557) system exhibits a strong anisotropy in conductance below 78 K, with the evolution of a characteristic chain structure. Here we show, using angle-resolved photoemission, that chain ordering results in complete ...
  • Fermi nesting between atomic wires with strong spin-orbit coupling 
    Tegenkamp, Christoph; Lükermann, Daniel; Pfnür, Herbert; Slomski, B.; Landolt, G.; Dil, J.H. (College Park, MD : American Physical Society, 2012)
    The mutual interplay between superlattice structures, band filling factors, and spin-orbit coupling results in a highly correlated electronic spin and charge state found for an array of atomic Pb wires grown on Si(557). ...
  • Kinetic and mechanistic features on the reaction of stored TiO2 electrons with Hg (II), Pb (II) and Ni (II) in aqueous suspension 
    Mohamed, Hanan H.; Alomair, Nuhad A.; Bahnemann, Detlef W. (Amsterdam : Elsevier BV, 2016)
    The reaction of electrons stored on TiO2 nanoparticles with heavy metal ions Hg (II), Ni (II) and Pb (II) has been studied employing steady state and stopped flow spectrophotometric techniques. Prior to kinetic investigation ...
  • Properties of geopolymer binders prepared from milled pond ash 
    Temuujin, J.; Minjigmaa, A.; Bayarzul, U.; Kim, D.S.; Lee, S.-H.; Lee, H.J.; Ruescher, C.H.; MacKenzie, K.J.D. (Madrid : Consejo Superior de Investigaciones Científicas (CSIC), 2017)
    Alkali-activated materials were prepared from pond ash from the Darkhan city (Mongolia) thermal power station. This ash contains about 60 wt % X-ray amorphous material in addition to quartz, mullite, hematite and ...
