    Article
    Restricted access - publisher's policy
    Low-flammability freeze-dried cellulose nanofibril (CNF)/sodium montmorillonite (MMT) aerogels with improved mechanical properties were fabricated via a facile cross-linking of boric acid (BA) and melamine-formaldehyde ...

  • Managing non-technical requirements in COTS components selection 

    Carvallo Vega, Juan Pablo; Franch Gutiérrez, Javier; Quer, Carme (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    Conference report
    Open Access
    The selection of COTS components is made not only by an analysis of their technical quality but also (and sometimes mostly) by considering how they fulfill those non-technical requirements considered relevant, which refer ...
