  • Brüning, J.; Denkena, Berend; Dittrich, Marc-André; Hocke, T. (Amsterdam : Elsevier, 2017)
    Automated Fiber Placement (AFP) processes are commonly deployed in manufacturing of lightweight structures made of carbon fibre reinforced polymer. In general, AFP is connected to individual manufacturing knowledge during ...
  • Denkena, Berend; Grove, Thilo; Schmidt, Carsten (Amsterdam : Elsevier B.V., 2018)
    In combustion engines a large percentage of mechanical losses result from friction, for example within the cylinder liner. In order to reduce the friction between cylinder liner and piston, micro dimples in the surface ...
  • Roth, Isabelle; Schumacher, Stephan; Basler, Tina; Baumert, Kathrin; Seitz, Jan-Marten; Evertz, Florian; Mueller, Peter Paul; Baeumer, Wolfgang; Kietzmann, Manfred (Heidelberg : Springer Heidelberg, 2015)
    Magnesium is currently under investigation as a prospective biodegradable implant material. Biodegradation of magnesium causes a release of magnesium, hydroxide ions and hydrogen gas but it can also lead to the formation ...
  • Ruffert, Christine (Basel : MDPI AG, 2016)
    Microfluidics is assumed to be one of the leading and most promising areas of research since the early 1990s. In microfluidic systems, small spherical magnetic particles with superparamagnetic properties, called magnetic ...
  • Schlangen, Sebastian; Bremer, Kort; Zheng, Yulong; Isaak, Andreas; Wurz, Marc Christopher; Böhm, Sebastian; Wellmann, Felix; Steinke, Michael; Pelegrina Bonilla, Gabriel; Neumann, Jörg; Kracht, Dietmar; Roth, Bernhard; Overmeyer, Ludger (Bellingham, WA : SPIE - International Society for Optical Engineering, 2018)
    Mode division multiplexing (MDM) could bring a technological progress in the field of optical telecommunication by increasing the data transmission bandwidth. A key challenge for enabling MDM lies in manufacturing of ...
  • Steggeman, Matthew (Hannover : Repositorium der Leibniz Universität Hannover, 2015-11-09)
    Employing paper as an engineering material is emerging in industry today. Paper-based technology has grown in the last several years. Current technology includes, but is not limited to, foldable paper microscopes, a disk ...
  • Behrens, Bernd-Arno; Chugreev, Alexander; Matthias, Tim; Poll, Gerhard; Pape, Florian; Coors, Timm; Hassel, Thomas; Maier, Hans Jürgen; Mildebrath, Maximilian (Basel : MDPI AG, 2019)
    Components subject to rolling contact fatigue, such as gears and rolling bearings, are among the fundamental machine elements in mechanical and vehicle engineering. Rolling bearings are generally not designed to be ...
  • Turger, Anke; Kohler, Jens; Denkena, Berend; Correa, Tomas A.; Becher, Christoph; Hurschler, Christof (London : Biomed Central Ltd., 2013)
    Background: Ceramic materials are used in a growing proportion of hip joint prostheses due to their wear resistance and biocompatibility properties. However, ceramics have not been applied successfully in total knee joint ...
  • Denkena, Berend; Köhler, Jens; Turger, Anke; Helmecke, Patrick; Correa, Tomas A.; Hurschler, Christof (Amsterdam : Elsevier, 2013)
    To date, bioceramics have not been applied successfully in total knee joint endoprostheses. Sintered bioceramics can be machined only by grinding and polishing processes. Due to high quality requirements, there are significant ...
  • Kelb, Christian; Rother, Raimund; Schuler, Anne-Katrin; Hinkelmann, Moritz; Rahlves, Maik; Prucker, Oswald; Müller, Claas; Rühe, Jürgen; Reithmeier, Eduard; Roth, Bernhard (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    We demonstrate the manufacturing of embedded multimode optical waveguides through linking of polymethylmethacrylate (PMMA) foils and cyclic olefin polymer (COP) filaments based on a lamination process. Since the two polymeric ...
  • Hoffmann, Gerd-Albert; Wolfer, Tim; Zeitler, Jochen; Franke, Jörg; Suttmann, Oliver; Overmeyer, Ludger (Bellingham, WA : S P I E - International Society for Optical Engineering, 2017)
    Optical data communication is increasingly interesting for many applications in industrial processes. Therefore mass production is required to meet the requested price and lot sizes. Polymer optical waveguides show great ...
  • Behrens, Bernd-Arno; Rolfes, Raimund; Vucetic, Milan; Reinoso, J.; Vogler, M.; Grbic, N. (Amsterdam : Elsevier B.V., 2014)
    In modern car body construction, multi-material and hybrid design is used, whereby short fibre reinforced plastics combined with light metals represent an interesting class of work-piece materials. In order to realize ...
  • Denkena, Berend; Grove, Thilo; Göttsching, Tim (London : Springer, 2017)
    The grinding process is still an important manufacturing process for the machining of automotive components. For power train components, ultra-high carbon steel (UHC-steel) is a promising new innovative alloy because of ...
  • Denkena, Berend; Busemann, Sarah; Gottwik, Lukas; Grove, Thilo; Wippermann, Andi (Amsterdam : Elsevier BV, 2017)
    The technological basis for a cost-effective and reliable grinding process of mixed oxide ceramics requires a fundamental understanding of the prevailing grinding mechanisms to maintain surface quality and strength ...
  • Demminger, Christian; Klose, Christian; Taptimthong, Piriya; Maier, Hans Jürgen (Amsterdam : Elsevier, 2014)
    Magnetic magnesium alloys have an inherent load-sensitive behavior. These alloys are manufactured by casting of magnesium alloyed with the ferromagnetic element cobalt. In this context, the magnetoelastic effect can be ...
  • Krühn, Tobias; Sohrt, Simon; Overmeyer, Ludger (Heidelberg : Springer Verlag, 2016)
    In this paper, we describe a conveyor matrix consisting of small-scale, multi-directional transport modules that are considerably smaller than the transported packets. If a large number of these modules are combined into ...
  • Urbano, Jose; Golowin, Andrej; Löhnert, Stefan; Bestle, Dieter (Les Ulis : EDP Sciences, 2018)
    Currently, prediction of crack initiation by corrosion pits is only possible by assuming regular geometrical shapes, such as semi-spheres or semi-ellipsoids. Moreover, typical fatigue life diagrams associate the crack ...
  • Thürer, Susanne Elisabeth; Uhe, Johanna; Golovko, Oleksandr; Bonk, Christian; Bouguecha, Anas; Behrens, Bernd-Arno; Klose, Christian (Pfaffikon : Scientific.Net, 2017)
