    • Colour and technology in historic decorated glazes and glasses 

      Molina Giralt, Glòria (Universitat Politècnica de Catalunya, 2014-05-09)
      Tesi
      Accés obert
      Historical decorated glass and glazed ceramics are studied with the object to determine the technology of production and to relate it with the optical properties (colour, shine, opacity). Four different case of study are ...

    • Comparison of the nanostructure and mechanical performance of highly exfoliated epoxy-clay nanocomposites prepared by three different protocols

      Article
      Accés obert
      Three different protocols for the preparation of polymer layered silicate nanocomposites based upon a tri-functional epoxy resin, triglycidyl para-amino phenol (TGAP), have been compared in respect of the cure kinetics, ...

    • ElectroCatalytic Activity of Nickel Foam with Co, Mo, and Ni Phosphide Nanostructures 

      Rezayat, Mohammad; Yazdi, Morteza Saghafi; Roa Rovira, Joan Josep (MDPI AG, 2022-04-27)
      Article
      Accés obert
      In this study, the electrocatalytic activity of nickel foam, which is activated by cobalt, molybdenum, and nickel phosphide nanostructures, is prepared by the plasma hydrothermal method for use in the release of hydrogen ...

    • Impact of biomimicry in the design of osteoinductive bone substitutes: nanoscale matters 

      Barba Serrahima, Albert; Díez Escudero, Anna; Español Pons, Montserrat; Bonany Mariñosa, Mar; Sadowska, Joanna Maria; Guillem Martí, Jordi; Ohman, Caroline; Persson, Cecilia; Manzanares, Maria Cristina; Franch, Jordi; Ginebra Molins, Maria Pau (2019-01-01)

      Article
      Accés obert
      A set of the Classic and official Jun ware shards found at various kilns at Yuzhou (Henan) are analyzed. The blue color and milky appearance of the glazes subject of intense debate as being due to either the glaze nanostructure ...

    • Maturation of biomimetic hydroxyapatite in physiological fluids: a physicochemical and proteomic study 

      Konka, Joanna Magdalena; Español Pons, Montserrat; Bosch Canals, Begoña María; de Oliveira, Eliandre; Ginebra Molins, Maria Pau (Elsevier, 2021-09-01)
