  1. 16. Electrochemical Deposition and Characterization of Thermoelectric Thin Films of Bismuth Telluride and Its Derivatives

    Författare :Yi Ma; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; efficiency; deposition mechanism; thermoelectric properties; Thermoelectric; thin films; bismuth telluride and its derivatives; nano-engineering; electrochemical deposition;

    Sammanfattning : Thermoelectric materials have attracted enormous academic and industrial interest recently due to the fact that they can be used in solid state devices for power generation and cooling applications. It is expected that such thermoelectric applications will eventually contribute to meet the energy challenge in the future if the performance of the current devices can be further promoted through an increase in thermoelectric efficiency of the materials.

  7. 20. An Experimental Study on Melt Fragmentation, Oxidation and Steam Explosion during Fuel Coolant Interactions

    Författare :Louis Manickam; Weimin Ma; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; severe accident; fuel coolant interactions; melt jet breakup; debris properties; steam explosion; oxidation; high-speed visualization; Physics; Fysik;

    Sammanfattning : Nordic type boiling water reactors (BWRs) adopt reactor cavity flooding as a severe accident mitigation strategy (SAMS) to achieve core melt fragmentation and long-term cooling of decay heat generating core debris. The qualification of this SAMS needs to address two main severe accident issues: debris bed coolability and steam explosion. LÄS MER
