    • Green nanocoatings based on the deposition of zirconium oxide: the role of the substrate 

      Bonamigo Moreira, Vitor; Puiggalí Jou, Anna; Jiménez Piqué, Emilio; Armelín Diggroc, Elaine Aparecida; Alemán Llansó, Carlos; Meneguzzi, Alvaro (Multidisciplinary Digital Publishing Institute (MDPI), 2021-02-23)
      Article
      Open Access
      Herein, the influence of the substrate in the formation of zirconium oxide monolayer, from an aqueous hexafluorozirconic acid solution, by chemical conversion and by electro-assisted deposition, has been approached. The ...

    • Mechanical properties of 12Ce-ZrO2/3Y-ZrO2 composites 

      Turón Viñas, Miquel; Roa Rovira, Joan Josep; García Marro, Fernando; Anglada Gomila, Marcos Juan (2015-12-01)
      Article
      Open Access
      12Ce-ZrO2/3Y-ZrO2 composites with different compositions have been prepared by presureless sintering at 1450 degrees C and the resulting microstructures have been correlated with their mechanical properties in terms of ...

    • Methanol steam reforming behavior of copper impregnated over CeO2-ZrO2 derived from a surfactant assisted coprecipitation route 

      Llorca Piqué, Jordi; Colussi, Sara; Domínguez Escalante, Montserrat; Trovarelli, Alessandro; Gayen, Arup; Das, Dipak (2015-09-07)
      Article
      Open Access
      A series of ceria-zirconia solid solutions has been prepared by a surfactant assisted coprecipitation method. After impregnation of copper, their activities have been assessed for methanol steam reforming. The results ...

    • Nanoindentación de capas finas de ZrW 

      Lucchini, Romain (Universitat Politècnica de Catalunya, 2009-02)
      Master thesis (pre-Bologna period)
      Open Access
      El objetivo de este proyecto es de determinar el mejor modelo analítico para caracterizar el comportamiento mecánico (modulo elástico y dureza) de una capa fina de ZrW depositada sobre un sustrato de sílice. Para el ...

    • Sequence of phase transformations in metastable ß Zr–12Nb alloy studied in situ by HEXRD and complementary techniques 

      Veverková, Anna; Harcuba, Petr; Vesely, Jozef; Barriobero Vila, Pere; Doležal, Pavel; Pospíšil, Jirí; Bartha, Kristína; Šmilauerová, Jana; Kozlík, Jirí; Stráský, Josef; Janecek, Miloš (Elsevier, 2023-03-01)
      Article
      Open Access
      Phase transformations in a metastable beta Zr–12Nb alloy were investigated by high-energy X-ray diffraction (HEXRD) measured simultaneously with thermal expansion in situ during linear heating from room temperature to 800 ...

    • The influence of unshielded small cracks in the fracture toughness of yttria and of ceria stabilised zirconia 

      Melk, Latifa; Turón Viñas, Miquel; Roa Rovira, Joan Josep; Antti, Marta-Lena; Anglada Gomila, Marcos Juan (Elsevier, 2016-01-01)
      Article
      Restricted access - publisher's policy
      The fracture toughness, Ric of two 3Y-ZrO2 with different grain size (177 and 330 nm) and 12Ce-ZrO2 were determined from a sharp micro-machined notch by Ultra-Short Pulsed Laser Ablation (UPLA) where a micro-cracked zone ...
