  • Behrens, Bernd-Arno; Hübner, Sven; Neumann, André (Amsterdam : Elsevier, 2014)
    Each material has its own advantages and disadvantages in terms of its mechanical, chemical and physical properties. Metallic materials are comparatively ductile and easy to process. Fibre reinforced plastics are very stiff ...
  • Alemdar, Semra; Hartwig, Steffen; Frister, Thore; König, Jan Christoph; Scheper, Thomas; Beutel, Sascha (New York City, NY : Springer Humana Press Inc., 2016)
    The α-humulene synthase from Zingiber zerumbet Smith was expressed as a polyhistidine-tagged protein in an E. coli BL21(DE3) strain. Induction time and inductor (isopropyl-β-D-thiogalactopyranoside) concentration were ...
  • 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 ...
  • Flesch, J.; Niedermeier, K.; Fritsch, A.; Musaeva, D.; Marocco, L.; Uhlig, R.; Baake, E.; Buck, R.; Wetzel, T. (Bristol : Institute of Physics Publishing, 2017)
    The use of liquid metals in solar power systems is not new. The receiver tests with liquid sodium in the 1980s at the Plataforma Solar de Almer a (PSA) already proved the feasibility of liquid metals as heat transfer fluid. ...
  • Leong, Kah Hon; Aziz, Azrina Abd; Sim, Lan Ching; Saravanan, Pichiah; Jang, Min; Bahnemann, Detlef W. (Frankfurt am Main : Beilstein-Institut zur Förderung der Chemischen Wissenschaften, 2018)
    The utilisation of sunlight as an abundant and renewable resource has motivated the development of sustainable photocatalysts that can collectively harvest visible light. However, the bottleneck in utilising the low energy ...
  • Gerstein, G.; Isik, K.; Gutknecht, F.; Sieczkarek, P.; Ewert, J.; Tekkaya, A.E.; Clausmeyer, T.; Nürnberger, F. (Bristol : Institute of Physics Publishing, 2017)
    The evolution of damage in geared components manufactured from steel sheets was investigated, to analyse the influence of damage caused by the sheet-bulk-metal forming. Due to the inhomogeneous and multi-axial deformation ...
  • Beese, Steffen; Loehnert, Stefan; Wriggers, Peter (Bristol : Institute of Physics Publishing, 2016)
    A ductile damage model for sheet bulk metal forming processes and its efficient and accurate treatment in the context of the Finite Element Method is presented. The damage is introduced as a non-local field to overcome ...
  • Witteck, Robert; Schulte-Huxel, Henning; Holst, Hendrik; Hinken, David; Vogt, Malte R.; Blankemeyer, Susanne; Köntges, Marc; Bothe, Karsten; Brendel, Rolf (London : Elsevier Ltd., 2016)
    Improving the light trapping in a module results in an increase in the generated current. Consequently, an optimization of the front grid metallization of the cell is required for the best trade-off between series resistance, ...
  • Zhou, Sheng; Wei, Yanying; Li, Libo; Duan, Yifan; Hou, Qianqian; Zhang, Lili; Ding, Liang-Xin; Xue, Jian; Wang, Haihui; Caro, Jürgen (Washington : American Association for the Advancement of Science (A A A S), 2018)
    Metal-organic framework (MOF) membranes show great promise for propene/propane separation, yet a sharp molecular sieving has not been achieved due to their inherent linker mobility. Here, zeolitic imidazolate framework ...
