  • Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure 

    Rodríguez-Tinoco, Cristian; Gonzalez Silveira, Marta; Barrio Casado, María del; Lloveras Muntané, Pol Marcel; Tamarit Mur, José Luis; Garden, Jean Luc; Rodríguez Viejo, Javier (Macmillan Publishers, 2016-10-03)
    Article
    Accés obert
    Pressure experiments provide a unique opportunity to unravel new insights into glass-forming liquids by exploring its effect on the dynamics of viscous liquids and on the evolution of the glass transition temperature. Here ...
  • Variable-range electron hopping, conductivity cross-over and space-charge relaxation in C60Br6 

    Manesh, Zachariah; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Tamarit Mur, José Luis; Barrio Casado, María del; Macovez, Roberto (2016-07-01)
    Article
    Accés restringit per política de l'editorial
    Dielectric spectroscopy is employed to probe the frequency-dependent conductivity and dipolar dielectric response of solid C60Br6. Below approximately 215 K, charge conduction is electronic and well described by Mott's ...
  • The structure of liquid water beyond the first hydration shell 

    Henao Aristizábal, Andrés; Busch, Sebastian; Guàrdia Manuel, Elvira; Tamarit Mur, José Luis; Pardo Soto, Luis Carlos (2016-06-22)
    Article
    Accés restringit per política de l'editorial
    To date there is a general consensus on the structure of the first coordination shells of liquid water, namely tetrahedral short range order of molecules. In contrast, little is known about the structure at longer distances ...
  • C60 solvate with (1,1,2)-trichloroethane: dynamic statistical disorder and mixed conformation 

    Mitsari, Efstratia; Romanini, Michela; Qureshi, Navid; Tamarit Mur, José Luis; Barrio Casado, María del; Macovez, Roberto (2016-05-27)
    Article
    Accés restringit per política de l'editorial
    We present a full characterization of the orientationally disordered cocrystal of C-60 with (1,1,2)-triChloroethane (C2H3Cl3), by means of X-ray diffraction, Raman spectroscopy, and broadband dielectric spectroscopy. Our ...
  • Structure and reorientational dynamics of 1-F-adamantane 

    Ben Hassine, Bacem; Negrier, Philippe; Romanini, Michela; Barrio Casado, María del; Macovez, Roberto; Kallel, A.; Mondieig, Denise; Tamarit Mur, José Luis (2016-03-17)
    Article
    Accés restringit per política de l'editorial
    The polymorphism and the dynamics of a simple rigid molecule (1-fluoro-adamantane) have been studied by means of X-ray powder diffraction and broadband dielectric spectroscopy. At temperatures below the melting point, the ...
  • Double primary relaxation in a highly anisotropic orientational glass-former with low-dimensional disorder 

    Romanini, Michela; Barrio Casado, María del; Capaccioli, Simon; Ruíz Martín, María Dolores; Macovez, Roberto; Tamarit Mur, José Luis (2016-04-26)
    Article
    Accés restringit per política de l'editorial
    The freezing of the cooperative reorientational motions in orientationally disordered (OD) molecular crystals marks the so-called \glassy" transition, which may be considered a lower-dimensional version of the structural ...
  • Modelling shape-memory effects in ferromagnetic alloys 

    Gebbia, Jonathan F.; Lloveras Muntané, Pol Marcel; Planes Vila, Antoni; Castán Vidal, Teresa; Saxena, Avadh (Springer, 2015-07-21)
    Article
    Accés restringit per política de l'editorial
    We develop a combined Ginzburg–Landau/micromagnetic model dealing with conventional and magnetic shape-memory properties in ferromagnetic shape-memory materials. The free energy of the system is written as the sum of ...
  • Competing structures within the first shell of liquid C2Cl6: a molecular dynamics study 

    Henao Aristizábal, Andrés; Pothoczki, Szilvia; Canales Gabriel, Manel; Guàrdia Manuel, Elvira; Pardo Soto, Luis Carlos (2014-02-28)
    Article
    Accés obert
    We present a detailed study on the liquid structure of hexachloroethane (C2Cl6) within the first shell using the proper Euler-angles convention. Molecular dynamics is used and the van der Waals picture of a liquid is taken ...
  • X-Ray Photon Correlation Spectroscopy Reveals Intermittent Aging Dynamics in a Metallic Glass 

    Evenson, Zach; Ruta, Beatrice; Hechler, Simon; Stolpe, Moritz; Pineda Soler, Eloi; Gallino, Isabella; Busch, Ralf (2015-10-21)
    Article
    Accés obert
    We use coherent x rays to probe the aging dynamics of a metallic glass directly on the atomic level. Contrary to the common assumption of a steady slowing down of the dynamics usually observed in macroscopic studies, we ...
  • Materials, techniques, and conservation of historic stained glass "Grisailles" 

    Pradell Cara, Trinitat; Molina Giralt, Glòria; Murcia, Sonia; Ibáñez De Aldecoa, Rafael; Liu, Chaoren; Molera Marimon, Judit; Shortland, A.J. (2016-03-01)
    Article
    Accés restringit per política de l'editorial
    A grisaille is a brown-blackish paint applied onto the inner surface of stained glass to draw the contours and details of the figures and to produce the effect of shades and volumes. Grisailles were traditionally made of ...
