Nanocomposite aerogels nanocomposites

Nanomaterials and molecular architectures (e.g., zeolite reactors, nanocomposite ceramic process technique, resists, NLO elements, catalysts with increased surface, systems of compact nanomaterials, i.e., membranes, polymers, light-absorbing material, aerogels, light emitters). 

Nanocomposite aerogels mainly consist as homogeneous dispersions of nanoparticles in an aerogel matrix. The preparation of nanocomposite aerogels can be...

The use of different metal aUcoxides to form the initial sol results in mixed aerogels (binary solid solutions of silica, titania, alumina, zirconia, vanadia, mtenia, etc.) that cannot be considered as nanocomposited. This field has also been largely explored for catalytic applications [10]. 

Nanocomposited carbon aerogels represent a different approach because of the organic nature of the precursory gel and the pyrolysis step [11]. In this case, high metal content can be achieved (up to 46% in the case of Pd-doped carbon aerogel)...
