    The structural and electronic properties of all-thiophene dendrimers and dendrons in solution have been evaluated using very different theoretical approaches based on quantum mechanical (QM) and hybrid QM/molecular mechanics ...
  • Spin glass behavior in an antiferromagnetic non-frustrated lattice: Sr2FeNbO6 perovskite 

    Rodríguez Solá, Raúl; Fernandez, Alberto; Isalgué Buxeda, Antonio; Rodriguez, Juan; Labarta, Amilcar; Tejada, Javier; Obradors, Xavier (The Institute of Physics, 1985-05-04)
    Article
    Restricted access - publisher's policy
    From magnetic susceptibility and hysteresis loop measurements on the cubic perovskite Sr2FeNbO6, it is shown that a spin glass transition does exist in this compound which has a non-frustrated lattice, and only antiferromagnetic ...
  • Strategies for surface modification with Ag-shaped nanoparticles: electrocatalytic enhancement of screen-printed electrodes for the detection of heavy metals 

    Torres Rivero Andrade, Karina Victoria Alejandra; Torralba Cadena, Lourdes; Espriu Gascon, Alexandra; Casas Pons, Ignasi; Bastos Arrieta, Julio Alonso; Florido Pérez, Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-30)
    Article
    Open Access
    Screen-printed carbon nanofiber electrodes (SPCNFEs) represent an alternative with great acceptance due to their results, as well as their low impact on the environment. In order to improve their performance, in the present ...
