AEROGELS – A VALUE ADDITION TO HARVEST SOLAR ENERGY
Abstract: Aerogels are a class of synthetic porous ultralight material that was created in 1930 and derived from a gel, in which the liquid component has been replaced with a gas without collapsing the gel structure by freeze-drying. It is made of silica, but carbon, iron oxide, gold, copper, polymer etc. can also be used. During freeze drying the liquid in the gel is slowly dried off without collapsing the solid …
