    • Improving the functional properties of (K0.5Na0.5)NbO3 piezoceramics by acceptor doping 

      Vendrell Villafruela, Xavier; García García, José Eduardo; Bril, X; Ochoa Guerrero, Diego A.; Mestres, Lourdes; Dezanneau, Guillem (Elsevier, 2015-01-01)
      Open Access
      ZrO2 and TiO2 modified lead-free (K0.5Na0.5)NbO3 (KNN) piezoelectric ceramics are prepared by a conventional solid-state reaction. The effect of acceptor doping on structural and functional properties is investigated. A ...
    • Mesoporous ceramic oxides as humidity sensors: A case study for gadolinium-doped ceria 

      Almar Liante, Laura; Tarancón Rubio, Albert; Andreu, Teresa; Torrell Faro, Marc; Hu, Yang; Dezanneau, Guillem; Morata García, Alejandro (2015-09-01)
