  • 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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Restricted access - publisher's policy
    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
    Open Access
    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
    Open Access
    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
    Restricted access - publisher's policy
    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 ...
  • Dynamic characterization of crystalline and glass phases of deuterated 1,1,2,2 tetrachloroethane 

    Perez, Silvina C.; Zuriaga, Jose Mariano; Serra, Pablo; Wolfenson, Alberto; Negrier, Philippe; Tamarit Mur, José Luis (2015-10-07)
    Article
    Restricted access - publisher's policy
    A thorough characterization of the gamma, beta, and glass phases of deuterated 1,1,2,2 tetrachloroethane (C2D2Cl4) via nuclear quadrupole resonance and Molecular Dynamic Simulations (MDSs) is reported. The presence of ...
  • Reversible adiabatic temperature changes at the magnetocaloric and barocaloric effects in Fe49Rh51 

    Stern-Taulats, Enric; Gracia-Condal, Adrià; Planes Vila, Antoni; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Tamarit Mur, José Luis; Pramanick, Sabyasachi; Majumdar, Subham; Mañosa Carrera, Lluis (2015-10-12)
    Article
    Restricted access - publisher's policy
    We report on the adiabatic temperature changes (Delta T) associated with the magnetocaloric and barocaloric effects in a Fe49Rh51 alloy, For the magnetocaloric effect, data derived from entropy curves are compared to direct ...
  • 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 ...
