Silica aerogels are the most common type of aerogel, and the primary type in use or study. [ 41 ] [ 57 ] It is silica -based and can be derived from silica gel or by a modified Stober process . Nicknames include frozen smoke , [ 58 ] solid smoke , solid air , solid cloud , and blue smoke , owing to its translucent nature and the way light ...
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 ...
Braun had been making videos, mainly tutorials, for fun since his teenage years, creating a YouTube channel on March 10, 2014. His first video was uploaded on March 24, 2014, and many of his early videos were recordings of his projects as a laboratory technician or at his parents' garage, with them later being filmed at his industrial-grade laboratory.

This gives them a significant advantage over earlier aerogels, which are brittle, glass-like substances. This elastomeric property in metallic microlattices furthermore results in efficient shock absorption. Their Young's modulus E exhibits different scaling, with the density ρ, E ~ ρ 2, compared to E ~ ρ 3 in aerogels and carbon nanotube ...

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.
Human uses of living things, including animals, plants, fungi, and microbes, take many forms, both practical, such as the production of food and clothing, and ...
