A microscopic look at the Johari-Goldstein relaxation in a hydrogenbonded glass-former
Caporaletti, Federico; Capaccioli, Simon; Valenti, Sofia; Mikolasek, Mirko; Chumakov, Aleksandr; Monaco, Giulio (Nature, 2019-10-04)
Article
Accés obertUnderstanding the glass transition requires getting the picture of the dynamical processes that intervene in it. Glass-forming liquids show a characteristic decoupling of relaxation processes when they are cooled down ... -
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 obertThe 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 ... -
Dynamics of orientationally disordered mixed crystal sharing Cl-adamantane and CN-adamantane
Martínez García, Julio Cesar; Capaccioli, Simon; Díez Berart, Sergio; Tamarit Mur, José Luis; Barrio Casado, María del; Veglio, Néstor Raúl; Pardo Soto, Luis Carlos (2010-01-27)
Article
Accés restringit per política de l'editorialOrientationally disordered (OD) mixed crystals formed between cyanoadamantane (CN-A) and chloroadamantane (Cl-A) have been thermodynamically characterized by means of thermal analysis and X-ray diffraction. The dynamics ... -
Emergence of glassy-like dynamics in an orientationally ordered phase
Romanini, Michela; Negrier, Philippe; Tamarit Mur, José Luis; Capaccioli, Simon; Barrio Casado, María del; Pardo Soto, Luis Carlos; Mondieig, Denise (2012-04-04)
Article
Accés obertThe dynamics of a simple rigid pseudoglobular molecule (2-adamantanone) has been studied by means of dielectric spectroscopy and examined under the constraints imposed by the space group of the crystal structure determined ... -
Experimental evidence of mosaic structure in strongly supercooled molecular liquids
Caporaletti, Federico; Capaccioli, Simon; Valenti, Sofia; Mikolasek, Mirko; Monaco, Giulio (2021-03-25)
Article
Accés obertWhen a liquid is cooled to produce a glass its dynamics, dominated by the structural relaxation, become very slow, and at the glass-transition temperature Tg its characteristic relaxation time is about 100¿s. At slightly ... -
Mixtures of m-fluoroaniline with apolar aromatic molecules: Phase behaviour, suppression of H-bonded clusters, and local H-bond relaxation dynamics
Romanini, Michela; Barrio Casado, María del; Macovez, Roberto; Capaccioli, Simon; Tamarit Mur, José Luis (2019-12-15)
Article
Accés obertWe employ differential scanning calorimetry, IR spectroscopy, X-ray powder diffraction and dielectric spectroscopy to characterize binary mixtures of m-fluoroaniline (mFA), a rigid-molecule glass former, with two ... -
Molecular dynamic in binary mixtures and polymer blends with large difference in glass transition temperatures of the two components: A critical review
Ngai, K.L.; Valenti, Sofia; Capaccioli, Simon (2019-09-11)
Article
Accés obertThe dynamics in highly asymmetric mixtures with large difference in Tg of the two components are complex. At low values of the lower-Tg2 component only the a1-relaxation and its Tga1 were found together with a fast relaxation. ... -
Thermodynamic scaling of the dynamics of a strongly hydrogen-bonded glass-former
Romanini, Michela; Barrio Casado, María del; Macovez, Roberto; Ruíz Martín, María Dolores; Capaccioli, Simon; Tamarit Mur, José Luis (Macmillan Publishers, 2017-12-01)
Article
Accés obertWe probe the temperature- and pressure-dependent specific volume (v) and dipolar dynamics of the amorphous phase (in both the supercooled liquid and glass states) of the ternidazole drug (TDZ). Three molecular dynamic ... -
α-relaxation dynamics of orientationally disordered mixed crystals composed of Cl-adamantane and CN-adamantane
Martínez García, Julio Cesar; Tamarit Mur, José Luis; Capaccioli, Simon; Barrio Casado, María del; Veglio, Néstor Raúl; Pardo Soto, Luis Carlos (American Institute of Physics (AIP), 2010-04-29)
Article
Accés restringit per política de l'editorialThe α-relaxation dynamics of 1-cyano-adamantane (CNA) and its mixtures with 1-chloro-adamantane (ClA) has been studied by means of broadband dielectric spectroscopy. The existence of orientationally disordered (OD) face ...
