A facile procedure was developed for the production of Al2O3 aerogels modified with tris(8-hydroxyquinolinato)aluminum complex (AlQ3). The addition of 8-hydroxyquinoline during the stage of alumina lyogel formation was found to increase gelation dura

SiO2-based aerogels have been produced be removing a solvent (ethanol or hexafluoroisopropanol) from lyogels both above and below the critical temperature of the alcohols (in the range 210–260 and 160–220°C, respectively). The resultant material
