Similarly, the compressive strength that describes the yield stress before plastic deformation under compression in graphene aerogels follows a power-law distribution: σ y /E s = (ρ/ρ s) n, where σ y is the compressive strength, ρ is the density of the graphene aerogel, E s is the modulus of graphene, ρ s is the density of graphene, and n ...

Boron nitride aerogel is an aerogel made of highly porous BN. It typically consists of a mixture of deformed BN 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
A complete shape recovery of a 3-mm-tall sample after it was compressed down to 0.1 mm is possible. Its ultimate tensile strength (UTS) depends on material density and is about 160 kPa at 8.5 mg/cm 3 and 1 kPa at 0.18 mg/cm 3; in comparison, the strongest silica aerogels have a UTS of 16 kPa at 100 mg/cm 3.
Ultralight materials are solids with a density of less than 10 mg/cm 3. Ultralight material is defined by its cellular arrangement and its stiffness and strength that make up its solid constituent. They include silica aerogels, carbon nanotube aerogels, aero graphite, metallic foams, polymeric foams, and metallic micro lattices. [1]

As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m 3) and the cgs unit of gram per cubic centimetre (g/cm 3) are probably the most commonly used units for density. One g/cm 3 is equal to 1000 kg/m 3. One cubic ...
