Aerogels made of cadmium selenide quantum dots in a porous 3-D network have been developed for use in the semiconductor industry. [73] Aerogel performance may be augmented for a specific application by the addition of dopants, reinforcing structures, and hybridizing compounds. For example, Spaceloft is a composite of aerogel with some kind of ...
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 ...
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.
Aspen Aerogels, Inc. (NYSE:ASPN) shares are trading higher after the company won a conditional commitment for a proposed DOE loan worth up to $670.6 million. This loan, part of the Advanced ...
In 2002, aerogel held the Guinness World Record for the least dense (lightest) solid. [17] Aerogel is mostly air because its structure is like that of a highly vacuous sponge. The lightness and low density is due primarily to the large proportion of air within the solid and not the silicon construction materials. [18]
This creates a nanofoam, a foam with most of its bubbles under 100 nanometres in size, giving the aerogel its unusual properties: Silica aerogel is the lowest-density solid yet created, actually lighter than air when in a vacuum (outside of a vacuum, air fills the pores, upping its density to slightly greater than air). It is also the best ...
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 1992.
