    • Crystal structure and solid-state studies of aged samples of tienoxolol, an API designed against hypertension 

      Teulon, Jean-Marie; Mahé, Nathalie; Do, Bernard; Nicolaï, Béatrice; Rietveld, Ivo B.; Barrio Casado, María del; Tamarit Mur, José Luis; Céolin, René; Ghéchot, Christophe (2012)
      Article
      Accés restringit per política de l'editorial
      Aging of drug molecules is generally studied following regulatory procedures, i.e. under forced conditions and for relatively limited storage time; therefore naturally aged samples are rare and provide scientific reference ...

    • First-principles modeling of quantum nuclear effects and atomic interactions in solid He-4 at high pressure 

      Cazorla Silva, Claudio; Boronat Medico, Jordi (2015-01-07)
      Article
      Accés obert
      We present a first-principles computational study of solid He-4 at T = 0 K and pressures up to similar to 160 GPa. Our computational strategy consists in using van der Waals density functional theory (DFT-vdW) to describe ...

    • Optimal Sample Preparation for the Analysis of Micrometric Heterogeneous Samples 

      Beltran Sanchidrian, Victòria; Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Cinque, Gianfelice; Wehbe, Katia; Pradell Cara, Trinitat (2015-05-29)
      Article
      Accés obert
      Precise microanalytical techniques are essential in many fields such as cultural heritage materials, showing complex layered microstructures containing a wide range of materials of diverse nature and hardness. Noninvasive ...

    • Poly(butylene azelate-co-butylene succinate) copolymers: Crystalline morphologies and degradation 

      Díaz Andrade, Angélica María; Franco García, María Lourdes; Estrany Coda, Francesc; Valle Mendoza, Luis Javier del; Puiggalí Bellalta, Jordi (2014-01)
      Article
      Accés restringit per política de l'editorial
      Random copolymers derived from 1,4-butanediol and two dicarboxylic units differing in the parity of the number of methylene groups and length of the polymethylene sequence (i.e. succinic and azelaic acids) were studied in ...

    • Residual stress distribution of a 6061-T6 aluminum alloy under shear deformation 

      Reyes Ruiz, Carlos; Figueroa, I. A.; Braham, C.; Cabrera Marrero, José M.; Zanellato, O.; Baiz, S.; González de Rivera, G. (2016-07-18)
      Article
      Accés obert
      There is a lack of information with regards to the friction effect in ECAPed aluminum alloys, even though it might substantially modify the deformation at the surface. In this work, the friction effect at the surface and ...

    • Structural polymorphism in poly(3-ethyl-3-phenyl-2-azetidinone) 

      Iribarren Laco, José Ignacio (Elsevier, 2016-08-31)
      Article
      Accés restringit per política de l'editorial
      The structural characterization of chiral nylon-3 derivative, poly (3-ethyl-3-phenyl-2- azetidinone) (PEPA) has been carried out using FTIR, thermal analysis, X-ray diffraction and electron microscopy. X-ray diffraction ...
