Metal oxide aerogels are used as catalysts in various chemical reactions/transformations or as precursors for other materials. Aerogels made with aluminium oxide are known as alumina aerogels. These aerogels are used as catalysts, especially when "doped" with a metal other than aluminium. Nickel–alumina aerogel is the most common combination.
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.
Ultralight materials are solids with a density of less than 10 mg/cm 3, including silica aerogels, carbon nanotube aerogels, aerographite, metallic foams, polymeric foams, and metallic microlattices. The density of air is about 1.275 mg/cm 3 , which means that the air in the pores contributes significantly to the density of these materials in ...
Metal chalcogenide aerogels can be prepared from thiolysis [5] or nanoparticle condensation [6] [7] and contain crystalline nanoparticles in the structure. [7] The synthetic method can be extended to many thioanions, including tetrathiomolybdate-based chalcogels. [8] Different metal ions have been used as linkers Co 2+, Ni 2+, Pb 2+, Cd 2+, Bi ...
It can be made from natural or synthetic sources. Other carbon materials used in CDI research are, for example, ordered mesoporous carbon, carbon aerogels, carbide-derived carbons, carbon nanotubes, graphene and carbon black. [6] Recent work argues that micropores, especially pores < 1.1 nm are the most effective for salt adsorption in CDI. [31]
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
BN aerogels can be prepared by template-assisted chemical vapor deposition at a temperature ~900 °C using borazine as the feed gas. [1] Alternatively it can be produced by ball milling h-BN powder, ultrasonically dispersing it in water, and freeze-drying the dispersion.
The use of nanocellulose in cosmetics and pharmaceuticals has been suggested: Freeze-dried nanocellulose aerogels used in sanitary napkins, tampons, diapers or as wound dressing; The use of nanocellulose as a composite coating agent in cosmetics e.g. for hair, eyelashes, eyebrows or nails
