    Bredow, T.; Tegenkamp, Christoph; Pfnür, Herbert; Meyer, J.; Maslyuk, V.V.; Mertig, I. (College Park, MD : American Institute of Physics, 2008)
    The interaction of ferrocene- 1, 1' -dithiol (FDT) with two parallel Ag(111) surfaces has been theoretically studied at density-functional level. The effect of surface defects on the energetic and electronic structure was ...
  • In vitro corrosion of ZEK100 plates in Hank's Balanced Salt Solution 
    Waizy, Hazibullah; Weizbauer, Andreas; Modrejewski, Christian; Witte, Frank; Windhagen, Henning; Lucas, Arne; Kieke, Marc D.K.; Denkena, Berend; Behrens, Peter; Meyer-Lindenberg, Andrea; Bach, Friedrich-Wilhelm; Thorey, Fritz (London : BioMed Central Ltd., 2012)
    Background: In recent years magnesium alloys have been intensively investigated as potential resorbable materials with appropriate mechanical and corrosion properties. Particularly in orthopedic research magnesium is ...
  • Influence of the grain size on the in vivo degradation behaviour of the magnesium alloy LAE442 
    Ullmann, Berit; Reifenrath, Janin; Seitz, Jan-Martin; Bormann, Dirk; Meyer-Lindenberg, Andrea (London : SAGE Publications Ltd., 2013)
    The aim of this study was to investigate the differences in the in vivo degradation behaviour of magnesium implants with various grain sizes and damaged surfaces. For this purpose, three different LAE442 magnesium implants ...
  • Light driven reactions of single physisorbed azobenzenes 
    Bazarnik, Maciej; Henzl, Jörg; Czajka, Ryszard; Morgenstern, Karina (Cambridge : Royal Society of Chemistry, 2011)
    We present a successful attempt of decoupling a dye molecule from a metallic surface via physisorption for enabling direct photoisomerization. Effective switching between the isomers is possible by exposure to UV light via ...
  • Light intensity dependence of the kinetics of the photocatalytic oxidation of nitrogen(ii) oxide at the surface of TiO2 
    Dillert, Ralf; Engel, Astrid; Große, Julia; Lindner, Patrick; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2013)
    Air pollution by nitrogen oxides represents a serious environmental problem in urban areas where numerous sources of these pollutants are concentrated. One approach to reduce the concentration of these air pollutants is ...
  • Mesoporous silica films as a novel biomaterial: Applications in the middle ear 
    Ehlert, Nina; Mueller, Peter P.; Stieve, Martin; Lenarz, Thomas; Behrens, Peter (Cambridge : Royal Society of Chemistry, 2013)
    In this tutorial review we present the process of the development of functional implants using mesoporous silica. The different steps from chemical synthesis and physicochemical characterization followed by in vitro testing ...
  • Metal-organic framework nanofibers via electrospinning 
    Ostermann, Rainer; Cravillon, Janosch; Weidmann, Christoph; Wiebcke, Michael; Smarsly, Bernd M. (Cambridge : Royal Society of Chemistry, 2011)
    A hierarchical system of highly porous nanofibers has been prepared by electrospinning MOF (metal-organic framework) nanoparticles with suitable carrier polymers. Nitrogen adsorption proved the MOF nanoparticles to be fully ...
  • Morphology and magnetic properties of ferriferous two-phase sodium borosilicate glasses 
    Naberezhnov, Alexander; Porechnaya, Nadezda; Nizhankovskii, Viktor; Filimonov, Alexey; Nacke, Bernard (New York, NY : Hindawi Publishing Corporation, 2014)
    This contribution is devoted to the study of morphology and magnetic properties of sodium borosilicate glasses with different concentrations (15, 20, and 25 wt.%) of α Fe2O3 in an initial furnace charge. These glasses were ...
  • A rolling-gliding wear simulator for the investigation of tribological material pairings for application in total knee arthroplasty 
    Richter, Berna I.; Ostermeier, Sven; Turger, Anke; Denkena, Berend; Hurschler, Christof (London : BioMed Central Ltd., 2010)
    Background: Material wear testing is an important technique in the development and evaluation of materials for use in implant for total knee arthroplasty. Since a knee joint induces a complex rolling-gliding movement, ...
