  • Nanostructured materials and their application in thermoelectric energy harvesting 
    Bittner, Michael (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Thermoelectric materials can, reversibly and without any moving parts, convert thermal energy into electrical energy by coupling an entropic and an electrical flux with each other. This ability is becoming increasingly ...
  • A novel CO2-stable dual phase membrane with high oxygen permeability 
    Liang, Fangyi; Luo, Huixia; Partovi, Kaveh; Ravkina, Olga; Cao, Zhengwen; Liu, Yi; Caro, Jürgen (Cambridge : Royal Society of Chemistry, 2014-01-10)
    By cobalt-doping of the mixed conducting phase PSFC, a good combination of high CO2 stability and high oxygen permeability is obtained for the 60 wt% Ce0.9Pr0.1O2-delta d -40 wt% Pr0.6Sr0.4Fe0.5Co0.5O3-delta (CP-PSFC) dual ...
  • Physico-Chemical development of oxide-based ceramics for thermoelectric energy harvesting 
    Hinterding, Richard (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    The thermoelectric effect describes the conversion of heat into electrical energy and it is the pivotal element for the utilization of waste heat via Energy Harvesting. Especially high-temperature applications in industrially ...
  • Wear investigation of selective α-Fe2O3 oxide layers generated on surfaces for dry sheet metal forming 
    Behrens, Bernd-Arno; Yilkiran, Deniz; Schöler, Simon; Özkaya, Fahrettin; Hübner, Sven; Möhwald, Kai (Amsterdam : Elsevier B.V., 2018)
    To realize a dry sheet metal forming process, α-Fe 2 O 3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens ...
