Aerogel — that mixture of air and silica — is one of those materials that seems like a miracle. It is almost not there since the material is 99% air. [NileRed] wanted to make his own and he ...

In the manufacturing process, super-critical extraction in the dryer transforms a wet, nanoporous gel into an ultra-clear, super-insulating aerogel sheet by removing all solvents from the material.

However, the mechanical properties of graphite are relatively weak due to the close stacking of the graphene sheets. To overcome this, a porous version of graphene, known as a graphene aerogel, can be ...
