    • Low molecular weight organic acid salts, markers of old fungi activity in wall paintings 

      Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Pradell Cara, Trinitat; Beltran Sanchidrian, Victòria; Cinque, Gianfelice; Juanhuix, Jordi; Font, Lídia; Senserrich, Rosa (2016-02-21)
      Article
      Accés obert
      Micro-Infrared Spectroscopy (mSR-FTIR) and X-ray diffraction (mSR-XRD) with synchrotron light, Gas Chromatography/Mass Spectrometry (CG/MS), Optical Microscopy (OM) and Scanning Electron Microscopy (SEM/EDS) were used ...

    • Melting of orientational degrees of freedom 

      Aznar Luque, Araceli; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Tamarit Mur, José Luis (2017-05)
      Article
      Accés obert
      We use calorimetry and dilatometry under hydrostatic pressure, X-ray powder diffraction and available literature data in a series of composition-related orientationally disordered (plastic) crystals to characterize both ...

    • Structural evolution of metallic glasses during annealing through in-situ Synchrotron X-ray diffract 

      Pineda Soler, Eloi; Boneu, Francesc; Bruna Escuer, Pere; Pradell Cara, Trinitat; Labrador, Ana; Crespo Artiaga, Daniel (2008-05)
      Article
      Accés obert
      In this work we study the structural evolution of Al and Fe based metallic glass compositions. The samples were obtained as ribbons by melt-spinning, their glass stability and crystallization were analyzed by calorimetry ...

    • Structural study of conventional and bulk metallic glasses during annealing 

      Pineda Soler, Eloi; Hidalgo, I.; Bruna Escuer, Pere; Pradell Cara, Trinitat; Labrador, Ana; Crespo Artiaga, Daniel (2007)
      Article
      Accés obert
      Metallic glasses with conventional glass-forming ability (Al-Fe-Nd, Fe-Zr-B, Fe-B-Nb compositions) and bulk metallic glasses (Ca-Mg-Cu compositions) were studied by synchrotron X-ray diffraction during annealing throughout ...
