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.
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.
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 ...

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 ...
One study reported an oxygen permeability of 0.0006 (cm 3 μm)/(m 2 day kPa) for a ca. 5 μm thin nanocellulose film at 23 °C and 0% RH. [49] In a related study, a more than 700-fold decrease in oxygen permeability of a polylactide (PLA) film when a nanocellulose layer was added to the PLA surface was reported. [43]
Oppose - Not as good as the other aerogel FP and I'm not sure why you think it's irreplaceable when we already have an existing FP and other pictures besides. This picture shows none of aerogel's interesting features (strength, insulation, etc); it might as well be a cube of jello. Matt Deres 01:08, 27 August 2007 (UTC) Oppose. It's a nice ...
