  • Denkena, Berend; Flöter, F. (Amsterdam : Elsevier BV, 2012)
    In the re-contouring process of aircraft engine components, the unknown geometry and inhomogeneous material properties of the workpiece are major challenges. For this reason a new repair process chain is supposed which ...
  • Ertl, G.; Koch, J. (Berlin : De Gruyter, 1970)
    The adsorption of CO on a clean Pd(lll) surface has been studied by means of low energy electron diffraction (LEED), contact potential measurements and flash desorption. At coverages ㊀ between 1/3 and 1/2 ordered adsorption ...
  • Wippo, V.; Jaeschke, P.; Brueggmann, M.; Suttmann, O.; Overmeyer, L. (Amsterdam : Elsevier B.V., 2014)
    Laser transmission welding can be used to join endless fibre reinforced thermoplastics. The welding temperature is affected by the heat conduction along carbon fibres and depends on the local orientation of the fibres in ...
  • Dubois, Jan; Muskulus, Michael; Schaumann, Peter (Amsterdam : Elsevier, 2013)
    Jacket substructures for offshore wind turbines show strong potentials in water depths from 25 up to 70m. A review of state-of-practice and enhanced state-of-the-art modeling of offshore wind turbine jackets is conducted ...
  • Schmidt, Jan; Werner, Florian; Veith, Boris; Zielke, Dimitri; Steingrube, S.; Altermatt, Pietro P.; Gatz, Sebastian; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    The surface passivation properties of aluminium oxide (Al 2O 3) on crystalline Si are compared with the traditional passivation system of silicon nitride (SiN x). It is shown that Al 2O 3 has fundamental advantages over ...
  • Gatz, Sebastian; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2012)
    In this paper, we investigate the impact of the rear surface passivation, the silicon base material and the local aluminum contacts applied to rear side passivated solar cells with a homogenously doped emitter at the front. ...
  • Gatz, Sebastian; Bothe, Karsten; Müller, Jens; Dullweber, Thorsten; Brendel, Rolf (Amsterdam : Elsevier BV, 2011)
    In this paper, we investigate the surface recombination of local screen-printed aluminum contacts applied to rear passivated solar cells. We measure the surface recombination velocity by microwave-detected photoconductance ...
  • Salfeld, Valerian; Matthias, Tim; Krimm, Richard; Behrens, Bernd-Arno (Amsterdam : Elsevier BV, 2012)
    This contribution deals with the process-machine interaction while forming parts by sheet-bulk metal forming. The goal of this process is to form complex functional elements, such as gearing and carrier elements, by means ...
  • Hennig, Tobias; Löwer, Lothar; Faiella, Luis Mariano; Stock, Sebastian; Jansen, Malte; Hofmann, Lutz; Rohrig, Kurt (Amsterdam : Elsevier, 2014)
    In this publication, the authors present methodology and example results for the analysis of ancillary services of an offshore wind farm cluster and its electrical power system. Thereby the operation tool Wind Cluster ...
  • Welly, J.D. (Berlin, Boston : De Gruyter, 1963)
    The velocity distribution of the electrons within a plasma shock front is investigated by methods of the kinetic theory arranged in a manner to account for heavy deviations from thermodynamic equilibrium. The distribution ...
  • Strugger, Siegfried (Berlin, Boston : De Gruyter, 1947)
    Das von Zernike, Köhler und Loos konstruierte Phasenkontrast-Mikroskop wird erstmalig an lebenden Metaphytenzellen zu zytologischen Untersuchungen angewandt. Zur Beobachtung der Plasmakonfiguration, der Chondriosomen sowie ...
  • Holst, Hendrik; Winter, Matthias; Vogt, Malte R.; Bothe, Karsten; Köntges, Marc; Brendel, Rolf; Altermatt, Pietro P. (Amsterdam : Elsevier, 2013)
    While ray tracing of solar cells was established decades ago, ray tracing of entire modules has met obstacles, mainly because module optics are affected by geometric structures varying over a large scale of dimensions. In ...
  • Haschke, Jan; Chen, Yi-Yang; Gogolin, Ralf; Mews, Mathias; Mingirulli, Nicola; Korte, Lars; Rech, Bernd (London : Elsevier Ltd., 2013)
    In this paper, interdigitated back contacted silicon heterojunction (IBC-SHJ) solar cell results as well as two dimensional device simulations are presented. The simulation indicates that for the minority contact (emitter) ...
  • Denkena, Berend; Dittrich, M.-A.; Uhlich, F.; Wichmann, M. (Amsterdam : Elsevier B.V., 2019)
    Over the recent years, several studies have pointed out the impact of manufacturing on the environment. Especially machining offers great potential for the conservation of energy, resources and the reuse of raw materials. ...
  • Denkena, Berend; Boess, V.; Nespor, D.; Rust, F.; Floeter, F. (Amsterdam : Elsevier, 2014)
    Re-contouring in the repair process of aircraft engine blades and vanes is a crucial task. Highest demands are made on the geometrical accuracy as well as on the machined surface of the part. Complexity rises even more due ...
  • Urmann, Katharina; Modrejewski, Julia; Scheper, Thomas; Walter, Johanna-Gabriela (Berlin : Walter de Gruyter, 2017)
    Aptamers are promising alternative binders that can substitute antibodies in various applications. Due to the advantages of aptamers, namely their high affinity, specificity and stability, along with the benefits originating ...
  • Walter, Johanna-Gabriela; Heilkenbrinker, Alexandra; Austerjost, Jonas; Timur, Suna; Stahl, Frank; Scheper, Thomas (Berlin : De Gruyter, 2012)
    Aptamers are single-stranded oligonucleotides composed of RNA or DNA that are able to bind their corresponding targets via molecular recognition. Thus, aptamers can be thought of as nucleic acidbased alternatives to ...
