  2. Aerogel - Wikipedia

    en.wikipedia.org/wiki/Aerogel

    An aerogel material can range from 50% to 99.98% air by volume, but in practice most aerogels exhibit somewhere between 90 and 99.8% porosity. [12] Aerogels have a porous solid network that contains air pockets, with the air pockets taking up the majority of space within the material. [13]

  3. Aerographene - Wikipedia

    en.wikipedia.org/wiki/Aerographene

    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.

  4. Boron nitride - Wikipedia

    en.wikipedia.org/wiki/Boron_nitride

    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 gas storage medium.

  6. Porosity - Wikipedia

    en.wikipedia.org/wiki/Porosity

    Porosity is a fraction between 0 and 1, typically ranging from less than 0.005 for solid granite to more than 0.5 for peat and clay. The porosity of a rock, or sedimentary layer, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain.

  7. Porosimetry - Wikipedia

    en.wikipedia.org/wiki/Porosimetry

    Porosimetry is an analytical technique used to determine various quantifiable aspects of a material's porous structure, such as pore diameter, total pore volume, surface area, and bulk and absolute densities. The technique involves the intrusion of a non-wetting liquid (often mercury) at high pressure into a material through the use of a ...

  8. Air permeability specific surface - Wikipedia

    en.wikipedia.org/wiki/Air_permeability_specific...

    ε is the volume porosity of the bed (dimensionless) δP is the pressure drop across the bed, Pa l is the cylinder length, m η is the air dynamic viscosity, Pa·s Q is the flowrate, m 3 ·s −1. It can be seen that the specific surface is proportional to the square root of the ratio of pressure to flow. Various standard methods have been ...

  9. Pore structure - Wikipedia

    en.wikipedia.org/wiki/Pore_structure

    Micro CT of porous medium: Pores of the porous medium shown as purple color and impermeable porous matrix shown as green-yellow color. Pore structure is a common term employed to characterize the porosity, pore size, pore size distribution, and pore morphology (such as pore shape, surface roughness, and tortuosity of pore channels) of a porous medium.
