      Open Access
      Nickel tin alloy nanoparticles (NPs) with tuned composition NixSn (0.6¿=¿x¿=¿1.9) were synthesized by a solution-based procedure and used as anode materials for Li-ion batteries (LIBs) and Na-ion batteries (SIBs). Among ...

    • Degradación de la resistencia a fractura de un carburo cementado WC-Ni sometido a choque térmico 

      Chen, Weikai (Universitat Politècnica de Catalunya, 2015-02)
      Bachelor thesis
      Restricted access - author's decision
      Los carburos cementados son materiales compuestos por carburos (generalmente de WC) incrustados en una matriz metálica (normalmente de cobalto) que actúa como ligante. Estos materiales se caracterizan por unas excelentes ...
