      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 ...

    • Uniaxial negative thermal expansion in crystals of tienoxolol 

      Nicolaï, Beatrice; Rietveld, Ivo B.; Barrio Casado, María del; Mahé, Nathalie; Tamarit Mur, José Luis; Céolin, René; Guéchot, Christophe; Teulon, Jean-Marie (2012-06-17)
      Article
      Accés restringit per política de l'editorial
      The thermal expansion of tienoxolol has been investigated by X-ray powder diffraction up to its melting temperature. The data indicate that the expansion is anisotropic and even negative in one direction of the unit cell. ...

    • Uniaxial negative thermal expansion in polymorphic 2-bromobenzophenone, due to aromatic interactions? 

      Romanini, Michela; Rietveld, Ivo B.; Barrio Casado, María del; Negrier, Philippe; Mondieig, Denise; Macovez, Roberto; Céolin, René; Tamarit Mur, José Luis (American Chemical Society, 2021-04-07)
      Article
      Accés obert
      The structure of the metastable form II of 2-bromobenzophenone, obtained by crystallization from the melt, has been determined by powder X-ray diffraction. Form II has been solved in the centrosymmetric monoclinic space ...

    • Universal critical-like scaling of dynamics in plastic crystals 

      Martínez García, Julio Cesar; Tamarit Mur, José Luis; Rzosca, S. J.; Drozd Rzosca, A.; Pardo Soto, Luis Carlos; Barrio Casado, María del (2011-01-15)
      Article
      Accés restringit per política de l'editorial
      Many theoretical models for the glassy dynamics have been proposed so far describing the changes in molecular dynamics along the extraordinary slowing down in the vitrification process of a disordered phase on cooling. ...

    • Van-der-Waals based solvates of C-60 with CBr2Cl2 and CBr2(CH3)(2) 

      Ye, Jin; Barrio Casado, María del; Céolin, René; Qureshi, Navid; Rietveld, Ivo B.; Tamarit Mur, José Luis (2016-09-30)
      Article
      Accés obert
      We demonstrate that solvates of fullerene C60 form very predictable structures with finely tunable properties through the choice of the second component or solvent. Cubic co-crystals of C60·12CCl2Br2 and C60·12CBr2(CH3)2 ...

    • 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 obert
      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 ...

    • Water-triggered conduction and polarization effects in a hygroscopic fullerene salt 

      Zachariah, Manesh; Tripathi, Pragya; Mitsari, Efstratia; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2014)

      Accés obert
      Impedance spectroscopy is employed to probe the frequency-dependent conductivity and dielectric response of the crystalline C60O24Na24 fulleride, both in its pure form obtained by heating to 473 K and in its bulk-hydrate ...

    • Water-Triggered Conduction Mediated by Proton Exchange in a Hygroscopic Fulleride and Its Hydrate 

      Zachariah, Manesh; Mitsari, Efstratia; Romanini, Michela; Zygouri, Panagiota; Gournis, Dimitrios; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2015-01-08)
      Article
      Accés obert
      Impedance spectroscopy is employed to probe the impact of water on the dc conductivity and ac dielectric response of the polycrystalline C-60(ONa)(24) fulleride, both in its bulk-hydrate form, stable only below 370 K, and ...

    • α-relaxation dynamics of orientationally disordered mixed crystals composed of Cl-adamantane and CN-adamantane
