Silica aerogels are the most common type of aerogel, and the primary type in use or study. [ 40 ] [ 56 ] It is silica -based and can be derived from silica gel or by a modified Stober process . Nicknames include frozen smoke , [ 57 ] solid smoke , solid air , solid cloud , and blue smoke , owing to its translucent nature and the way light ...
Aerographene or graphene aerogel is the least dense solid known to exist, at 160 g/m 3 (0.0100 lb/cu ft; 0.16 mg/cm 3; 4.3 oz/cu yd). [1] The material reportedly can be produced at the scale of cubic meters.
Boron nitride aerogel is an aerogel made of highly porous boron nitride (BN). It typically consists of a mixture of deformed boron nitride nanotubes and nanosheets . It can have a density as low as 0.6 mg/cm 3 and a specific surface area as high as 1050 m 2 /g, and therefore has potential applications as an absorbent , catalyst support and gas ...
Hydrogen fluoride is lighter than air and could theoretically be used as a lifting gas. However, it is extremely corrosive, highly toxic, expensive, is heavier than other lifting gases, and has a low boiling point of 19.5 °C. Its use would therefore be impractical.
SEAgel (Safe Emulsion Agar gel) is one of a class of high-tech foam materials known as aerogels.It is an excellent thermal insulator and among the least dense solids known. . SEAgel was invented by Robert Morrison at the Lawrence Livermore National Laboratory in 19
Metal chalcogenide aerogels can be prepared from thiolysis [5] or nanoparticle condensation [6] [7] and contain crystalline nanoparticles in the structure. [7] The synthetic method can be extended to many thioanions, including tetrathiomolybdate-based chalcogels. [8] Different metal ions have been used as linkers Co 2+, Ni 2+, Pb 2+, Cd 2+, Bi ...
