Aerogels are reborn thanks to a new chemical process and the needs of particle colliders.
The evolution of aerogel throughout the second half of the 20th Century and the beginning of the 21st Century.
Aerogel production becomes safer and a new class of electrically conductive aerogels are invented.
Aerogels are made without supercritical drying, interest in commercializing aerogels reemerges, and aerogels enable discoveries in space.
Exciting new compositions become possible and aerogels are finally recommercialized.
Some comments about the future of aerogel.
