Either way, in 1931 Kistler published a paper in Nature (vol. 127, p. 741) titled "Coherent Expanded Aerogels and Jellies". He left his teaching post at the University of Illinois in 1935 and signed a contract with Monsanto Company in the early 1940s to start developing granular silica aerogel products under the trademark Santocel. Largely used ...
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.

This is a little undersize for a normal FP, I know, however, Aerogels are not available in any quantities outside of NASA, the Jet Propulsion Laboratory, and related agencies, so the image is essentially irreplaceable. This is one of my favourite science images, and I think well-deserving of an FP. Vanished user talk 18:48, 26 August 2007 (UTC)

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.
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 ...
