Aerogels may be used to separate oil from water, which could for example be used to respond to oil spills. [104] [81] [76] Aerogels may be used to disinfect water, killing bacteria. [105] [106] Aerogel can introduce disorder into superfluid helium-3. [107] In aircraft de-icing, a new proposal uses a carbon nanotube aerogel. A thin filament is ...
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 ...

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 ]
This is a list of insulation materials used around the world.. Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value.
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.
