    Article
    Open Access
    Due to the structurally disordered arrangement of atoms and deviation from thermodynamic equilibrium, the physical and mechanical properties of metallic glasses can vary with time, temperature and magnitude of strain or ...

  • Carbonation of fresco mural paintings with a dolomitic mortar 

    Oriols Pladevall, Núria; Salvadó Cabré, Nativitat; Pradell Cara, Trinitat; Buti Papiol, Salvador; Cotte, Marine; Gonzalez, Victor (2022-07)
    Article
    Open Access
    A fresco painting has a calcium carbonate binder produced as result of the carbonation process of a lime paste. The reaction environmental conditions are similar to those of bio-mineral formation where an amorphous cal-cium ...

  • Comprehensive insights into the thermal and mechanical effects of metallic glasses via creep 

    Xu, Z R; Qiao, J. C.; Wang, Jun; Pineda Soler, Eloi; Crespo Artiaga, Daniel (2022-02-10)
    Article
    Restricted access - publisher's policy
    Evolution of deformation and relaxation behaviors of a prototypic metallic glass was explored by extensive creep tests under both physical aging and cyclic loading. Deep insights into the microstructure-induced dynamic ...

  • Manganese crystalline phases developed in high lead glazes during firing 

    Molera Marimon, Judit; Colomer, Miquel; Vallcorba, Oriol; Pradell Cara, Trinitat (Elsevier, 2022-08-13)
    Article
    Open Access
    A High Temperature Synchrotron Radiation X-Ray Powder Diffraction experiment was performed to determine the manganese compounds formed during the heating and cooling of 70 wt% PbO – 30 wt% SiO2 mixture or the equivalent ...

  • An experimental and numerical investigation on fatigue of composite and metal aircraft structures 

    Pitta, Siddharth; Rojas Gregorio, José Ignacio; Roure Fernández, Francisco; Crespo Artiaga, Daniel; Wahab, Magd Abdel (2022-04)
    Article
    Open Access
    The static strength and fatigue crack resistance of the aircraft skin structures depend on the materials used and joint type. Most of the commercial aircraft’s skin panel structures are made from aluminium alloy and carbon ...
