Aerogel contains particles that are 2–5 nm in diameter. After the process of creating aerogel, it will contain a large amount of hydroxyl groups on the surface. The hydroxyl groups can cause a strong reaction when the aerogel is placed in water, causing it to catastrophically dissolve in the water.
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 ...

Graphene aerogels have a Young's modulus on the order of 50 MPa. [7] They can be compressed elastically to strain values >50%. [6] The stiffness and compressibility of graphene aerogels can be attributed in part to the strong sp 2 bonding of graphene and the π-π interaction between carbon sheets.
Launched in 2007, [1] [2] Amazon Vine is an internal service of Amazon.com that allows manufacturers and publishers to receive reviews for their products on Amazon. [3] [4] [5] Companies pay a fee to Amazon and provide products for review. The products are then passed to Amazon reviewers, who can publish a review.
A chalcogel or properly metal chalcogenide aerogel is an aerogel made from chalcogenides. [1] Chalcogels preferentially absorb heavy metals, [ 2 ] such as mercury , lead , and cadmium , from water. [ 3 ]
