  • 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 ...
  • Characterization of mechanical relaxation in a Cu-Zr-Al metallic glass 

    Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2015-09-15)
    Article
    Restricted access - publisher's policy
    The temperature dependence of the relaxation times of Cu46Zr46Al8 glass was measured by means of mechanical spectroscopy and static stress-relaxation measurements. The weak intensity of secondary relaxation in this alloy ...
  • Innovative NDT technique based on ferrofluids for detection of surface crack 

    Rojas Gregorio, José Ignacio; Cabrera, Blai; Musterni Girbau, Gerard; Nicolas, Jorge; Tristancho Martínez, Joshua; Crespo Artiaga, Daniel (2015-11)
    Article
    Restricted access - publisher's policy
    An innovative NDT technique is proposed for surface inspection of materials not necessarily magnetic or conductive, based on local magnetic field variations due to ferrofluid deposited in the cracks. The feasibility of the ...
  • Mechanical relaxation of metallic glasses: an overview of experimental data and theoretical models 

    Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2015-06)
    Article
    Open Access
    Relaxation phenomena in glasses are a subject of utmost interest, as they are deeply connected with their structure and dynamics. From a theoretical point of view, mechanical relaxation allows one to get insight into the ...
