  • Aqueous electrolytes confined within functionalized silica nanopores 

    Videla, Pablo; Sala Viñas, Jonàs; Martí Rabassa, Jordi; Guàrdia Manuel, Elvira; Laria, Daniel (2011-09-09)
    Article
    Open Access
    Molecular dynamics simulations have been carried out to investigate structural and dynamical characteristics of NaCl aqueous solutions confined within silica nanopores in contact with a “bulk-like” reservoir. Two types of ...
  • Determinación del coeficiente de difusión de colorantes directos y su relación con la concentración del electrolito. 

    Ribé Pons, José (Instituto de Investigación Textil y Cooperación Industrial, 1969-04)
    Article
    Open Access
    Este trabajo consta de dos partes. La primera de ellas consiste en establecer una técnica adecuada para las determinaciones de los coeficientes de difusión, y la segunda parte es el estudio de la influencia del electrolito ...
  • Efecto de la temperatura en los electrolitos de YSZ obtenidos por proyección térmica para las pilas de combustible de óxido solido 

    Sarrassat, Joseph (Universitat Politècnica de Catalunya, 2015-02)
    Master thesis (pre-Bologna period)
    Open Access
    Las pilas de combustible son sistemas electroquímicos en los cuales la energía química se transforma directamente en electricidad a través de una reacción redox. Una pila de combustible permite producir electricidad en ...
  • Experimental and theoretical study of nanofiltration of weak electrolytes: SO4 2–/HSO4 –/H+ system 

    López Rodríguez, Julio; Reig i Amat, Mònica; Yaroshchuk, Andriy; Licon Bernal, Edxon Eduardo; Gibert Agulló, Oriol; Cortina Pallás, José Luís (2018-03-15)
    Article
    Restricted access - publisher's policy
    © 2018 Elsevier B.V. Over recent years, nanofiltration (NF) has been considered as an effective way to improve processing steps in metallurgical and hydrometallurgy applications dealing with mixtures of metal ions in ...
  • Inkjet printing in polymer electrolyte membrane electrolysis 

    Bach Valls, Antoni (Universitat Politècnica de Catalunya / University of Alberta, 2016)
    Master thesis
    Open Access
    In proton exchange membrane fuel cells (PEFCs), the catalyst and electrolyte loading have been shown to have an important effect in the performance and efficiency of the device. On the contrary, literature analyzing ...
  • Self-Diffusion, Phase Behavior, and Li+ Ion Conduction in Succinonitrile-Based Plastic Cocrystals 

    Zachariah, Manesh; Romanini, Michela; Tripathi, Pragya; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2015-11-11)
    Article
    Open Access
    We study the temperature-dependent molecular dynamics, ion conduction, and phase behavior of plastic-crystal electrolytes based on the succinonitrile molecule. We employ calorimetry and dielectric spectroscopy to probe ...
  • Specific ion effects in aqueous eletrolyte solutions confined within graphene sheets at the nanometric scale 

    Sala Viñas, Jonàs; Guàrdia Manuel, Elvira; Martí Rabassa, Jordi (2012-08-14)
    Article
    Restricted access - publisher's policy
    The underlying mechanisms of specific ion effects on structure and dynamics of aqueous solutions have been long debated. On the other hand, the role of polarization at hydrophobic interfaces when aqueous electrolytes are ...
  • The bridge functions of molten salts 

    Tasseven, Çetin; Enrique González, Luis; Silbert, Moises; Alcaraz Sendra, Olga; Trullàs Simó, Joaquim (2001-09)
    Article
    Open Access
    The bridge functions of molten NaCl and AgI near melting were obtained by using the model potentials of Born–Huggins–Mayer for NaCl and Vashishta–Rahman for AgI. The calculations of the bridge functions involved molecular ...
