  • Solid state physicochemical properties and applications of organic and metallo-organic fullerene derivatives 

    Mitsari, Efstratia; Romanini, Michela; Manesh, Zachariah; Macovez, Roberto (2016)
    Article
    Accés obert
    We review the fundamental properties and main applications of organic derivatives and complexes of fullerenes in the solid-state form. We address in particular the structural properties, in terms of crystal structure, ...
  • Modeling of the Sub-Tg Relaxation Spectrum of Pd42.5Ni7.5Cu30P20 Metallic Glass 

    Liu, Chaoren; Pineda Soler, Eloi; Crespo Artiaga, Daniel; Qiao, Jichao (2016-03-17)
    Article
    Accés obert
    In this work we study the mechanical relaxation spectrum of Pd42.5Ni7.5Cu30P20 metallic glass. The effect of aging on the relaxation behavior is analyzed by measuring the internal friction during consecutive heating runs. ...
  • TREMOR – Technology Resources for Earthquake Monitoring & Response 

    Rojas Gregorio, José Ignacio (2007-08)
    Report de recerca
    Accés restringit per política de l'editorial
    Earthquakes represent a major hazard for populations around the world, causing frequent loss of life, human suffering, and enormous damage to homes, other buildings, and infrastructure. The Technology Resources for ...
  • Certification of UN heliports for night operations 

    Rojas Gregorio, José Ignacio (2009-07)
    Report de recerca
    Accés obert
    For strategic reasons, it is very important to increase the number of heliports certified for UN helicopter operations, as this enhances the efficiency of the UN Peacekeeping Missions. For instance, increased availability ...
  • Briefing on meetings at & reports by the 65th & 66th United Nations General Assembly 

    Rojas Gregorio, José Ignacio (2011)
    Report de recerca
    Accés obert
    No relevant differences are observed or identified after perusal of the space-related resolutions and documents issued by the UN System between 2010 and 2011. The most remarkable statements remain virtually unchanged in ...
  • Relaxation dynamics of Fe55Cr10Mo14C15B6 metallic glass explored by mechanical spectroscopy and calorimetry measurements 

    Liu, Chaoren; Madinehei, Seyed Milad; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2016-08-01)
    Article
    Accés obert
    In this work, the mechanical relaxation dynamics of Fe55Cr10Mo14C15B6 metallic glass is explored by mechanical spectroscopy. The temperature-dependent loss modulus E″(T) shows the features of β relaxation well below glass ...
  • Inverse barocaloric effects in ferroelectric BaTiO3 ceramics 

    Stern-Taulats, Enric; Lloveras Muntané, Pol Marcel; Barrio Casado, María del; Defay, Emmanuel; Egilmez, Mehmet; Planes Vila, Antoni; Tamarit Mur, José Luis; Mañosa Carrera, Lluis; Mathur, N.D.; Moya Raposo, Xavier (American Institute of Physics (AIP), 2016-09-19)
    Article
    Accés obert
    We use calorimetry to identify pressure-driven isothermal entropy changes in ceramic samples of the prototypical ferroelectric BaTiO3. Near the structural phase transitions at ~400 K (cubic-tetragonal) and ~280 K ...
  • On the positional and orientational order of water and methanol around indole: a study on the microscopic origin of solubility 

    Henao Aristizábal, Andrés; Johnston, Andrew J; Guàrdia Manuel, Elvira; McLain, Sylvia E.; Pardo Soto, Luis Carlos (2016-09-07)
    Article
    Accés restringit per política de l'editorial
    Although they are both highly polar liquids, there are a number of compounds, such as many pharmaceuticals, which show vastly different solubilities in methanol compared with water. From theories of the hydrophobic effect, ...
  • Degradation of azo dyes by rapidly solidified metallic particles 

    Mbarek Wael, Ben; Pineda Soler, Eloi; Khitouni, Mohamed; Fiol Santalo, Núria; Escoda, Lluïsa; Suñol Martinez, Juan Jose (2015)
    Comunicació de congrés
    Accés obert
    Azo compounds are one of the most common families of dyes used in textile and leather treatments. An important step during the treatment of water polluted by these compounds, is the degradation of the compounds by ...
  • Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure 

    Rodríguez-Tinoco, Cristian; Gonzalez Silveira, Marta; Barrio Casado, María del; Lloveras Muntané, Pol Marcel; Tamarit Mur, José Luis; Garden, Jean Luc; Rodríguez Viejo, Javier (Macmillan Publishers, 2016-10-03)
    Article
    Accés obert
    Pressure experiments provide a unique opportunity to unravel new insights into glass-forming liquids by exploring its effect on the dynamics of viscous liquids and on the evolution of the glass transition temperature. Here ...
