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 ...
The Commission for Agricultural Costs and Prices (CACP) is an attached office under the Ministry of Agriculture & Farmers Welfare, Government of India, that recommends Minimum Support Prices (MSPs) for select crops. It was established in 1965 [2] as the Agricultural Prices Commission, and was given its present name in 1985. [3]
Per-kilogram prices of some synthetic radioisotopes range to trillions of dollars. ... ( mg / kg ) Price [7] Year Source Notes USD/kg USD/L [c] 1: H: Hydrogen ...
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 ]
CNCs could also be made to gel in water under low power sonication giving rise to aerogels with the highest reported surface area (>600m2/g) and lowest shrinkage during drying (6.5%) of cellulose aerogels. [66] In another study by Aulin et al., [68] the formation of structured porous aerogels of nanocellulose by freeze-drying was demonstrated ...
