    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 ...
  • Lensing, Rebecca; Behrens, Peter; Müller, Peter Paul; Lenarz, Thomas; Stieve, Martin (London : SAGE Publications Ltd., 2014)
    Magnesium alloys have been investigated in different fields of medicine and represent a promising biomaterial for implants due to characteristics like bioabsorbability and osteoinduction. The objective of this study was ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
