aerogel: [1] comprised of a microporous solid in which the dispersed phase is a gas. (See Gold Book entry for note.) [2] Aerogels are a class of synthetic porous ...
Inventor of aerogels Samuel Stephens Kistler (March 26, 1900 – November 6, 1975) was an American scientist and chemical engineer , best known as the inventor of aerogels , one of the lightest known solid materials.
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.
Ultralight materials are solids with a density of less than 10 mg/cm 3, including silica aerogels, carbon nanotube aerogels, aerographite, metallic foams, polymeric foams, and metallic microlattices. The density of air is about 1.275 mg/cm 3 , which means that the air in the pores contributes significantly to the density of these materials in ...
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
A complete shape recovery of a 3-mm-tall sample after it was compressed down to 0.1 mm is possible. Its ultimate tensile strength (UTS) depends on material density and is about 160 kPa at 8.5 mg/cm 3 and 1 kPa at 0.18 mg/cm 3; in comparison, the strongest silica aerogels have a UTS of 16 kPa at 100 mg/cm 3.
The previous record of 1.0 mg/cm 3 was held by silica aerogels, and aerographite is claimed to have a density of 0.2 mg/cm 3. [11] Mechanically, these microlattices are behaviorally similar to elastomers and almost completely recover their shape after significant compression. [ 12 ]
Mowe says he opted for Polarthin’s aerogel—the aerogel technology was first created as a lightweight material for space travel that was later adapted to be less brittle for additional uses ...
