Editorial on Special Issues “Aerogels” and “Aerogels 2018” [PDF]

open access: yesGels, 2020
Aerogels can be defined as ultralight materials with a 3D porous structure, similar to their parent wet gels, where the solvent has been replaced by a gas without a collapse of the gel structure, thanks to the drying process used (supercritical CO2 drying, freeze drying, etc [...]
