    Article
    Open Access
    Three different protocols for the preparation of polymer layered silicate nanocomposites based upon a tri-functional epoxy resin, triglycidyl para-amino phenol (TGAP), have been compared in respect of the cure kinetics, ...

  • A simple spatiotemporal evolution model of a transmission power grid 

    Rosas Casals, Martí; Valverde, Sergi; Solé, Ricard Vicenç (2018-02-22)
    Article
    Open Access
    In this paper, we present a model for the spatial and temporal evolution of a particularly large human-made network: the 400-kV French transmission power grid. This is based on 1) an attachment procedure that diminishes ...
