    Article
    Accés obert
    The specific volume of vitamin C has been investigated by X-ray powder diffraction as a function of temperature from 110¿K up to complete degradation around 440¿K. Its thermal expansion is relatively small in comparison ...
  • Orientational order in the stable buckminster fullerene solvate C60·2CBr2H2 

    Ye, Jin; Barrio Casado, María del; Negrier, Philippe; Qureshi, Navid; Rietveld, Ivo B.; Céolin, René; Tamarit Mur, José Luis (2017-04-01)
    Article
    Accés obert
    Crystals of the solvate C60·2CBr2H2 (monoclinic C2/m), which is stable in air, were grown by slow evaporation of solutions of C60 in CBr2H2 at room temperature. The high enthalpy change for the complete desolvation process, ...
  • Modelling human behaviour in a bumper car ride using molecular dynamics tools: a student project 

    Buendía Morales, Jorge Juan; López Ospina, Hector; Sanchis, Guillem; Pardo Soto, Luis Carlos (2017-05-01)
    Article
    Accés obert
    Amusement parks are excellent laboratories of physics, not only to check physical laws, but also to investigate if those physical laws might also be applied to human behaviour. A group of Physics Engineering students from ...
  • Estudi de les colradures sobre or i plata del retaule barroc de sant Ruf de la catedral de Santa Maria de Tortosa 

    Clemente Martínez, Carme; Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Pradell Cara, Trinitat (2015-07)
    Article
    Accés obert
    Els segles XVII i XVIII són el moment de màxim esplendor a tota Europa en l’ús de les colres de colors. La tècnica de les colres de colors sobre fulls d’or o plata de l’època barroca està poc estudiada des del punt de ...
  • Pressure-temperature phase diagram of the dimorphism of the anti-inflammatory drug nimesulide 

    Barrio Casado, María del; Huguet, Jordi; Robert, B.; Rietveld, Ivo B.; Céolin, René; Tamarit Mur, José Luis (2017-06-15)
    Article
    Accés obert
    Understanding the phase behavior of active pharmaceutical ingredients is important for formulations of dosage forms and regulatory reasons. Nimesulide is an anti-inflammatory drug that is known to exhibit dimorphism; however ...
  • 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, Simone; Tamarit Mur, José Luis (Macmillan Publishers, 2017-12-01)
    Article
    Accés obert
    We 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 ...
  • Study on Mechanical Relaxations of 7075 (Al–Zn–Mg) and 2024 (Al–Cu–Mg) Alloys by Application of the Time-Temperature Superposition Principle 

    Rojas Gregorio, José Ignacio; Nicolas, Jorge; Crespo Artiaga, Daniel (2017-04-05)
    Article
    Accés obert
    The viscoelastic response of commercial Al–Zn–Mg and Al–Cu–Mg alloys was measured with a dynamic-mechanical analyzer (DMA) as a function of the temperature (from 30 to 425ºC) and the loading frequency (from 0.01 to 150 ...
  • Rapid degradation of azo-dye using Mn-Al powders produced by ball-milling 

    Mbarek Wael, Ben; Azabou, M.; Pineda Soler, Eloi; Fiol Santalo, Núria; Escoda, Lluïsa; Suñol Martinez, Juan Jose; Khitouni, Mohamed (2017-01-01)
    Article
    Accés obert
    This study was conducted on the reduction reaction of the azo dye Reactive Black 5 by means of the Mn85Al15 particles prepared by melt-spinning and ball-milling processes. The morphology, the surface elementary composition ...
  • Protonic surface conductivity and proton space-charge relaxation in hydrated fullerol 

    Mitsari, Efstratia; Romanini, Michela; Barrio Casado, María del; Tamarit Mur, José Luis; Macovez, Roberto (2017-03-09)
    Article
    Accés restringit per política de l'editorial
    The ac dielectric properties of both anhydrous fullerol (C-60(OH)(24)) and hydrated fullerol with 20% water mass content are investigated by means of temperature-dependent dielectric spectroscopy. Anhydrous polycrystalline ...
  • Pendulum dynamics in an amusement park 

    Gurri Pérez, Pol; Amat, David; Espar Masip, Joan; Puig, Jordi; Jiménez Machado, Gerard; Sendra Molins, Lluc; Pardo Soto, Luis Carlos (2017-05-01)
    Article
    Accés obert
    Pendulums have long been used to to determine the kinematics of non-inertial rotating systems. A proper study of this classical mechanical device under the action of a rotating reference frame can fully describe the behavior ...
