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.
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.
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 ...

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
However, NNSA Administrator Tom D'Agostino disclosed the role of Fogbank in the weapon: "There's another material in the—it's called interstage material, also known as Fogbank", and arms experts believe that Fogbank is an aerogel material which acts as an interstage material in a nuclear warhead; i.e., a material designed to become a ...
Either way, in 1931 Kistler published a paper in Nature (vol. 127, p. 741) titled "Coherent Expanded Aerogels and Jellies". He left his teaching post at the University of Illinois in 1935 and signed a contract with Monsanto Company in the early 1940s to start developing granular silica aerogel products under the trademark Santocel. Largely used ...
[1] [2] [3] These complex networks of polymers present a unique opportunity in the field of drug delivery at the intersection of nanoparticles and hydrogel synthesis. [ 1 ] [ 2 ] [ 3 ] Nanogels can be natural, synthetic, or a combination of the two and have a high degree of tunability in terms of their size, shape, surface functionalization ...
