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.
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 ...
Stardust was a 385-kilogram robotic space probe launched by NASA on 7 February 1999. Its primary mission was to collect dust samples from the coma of comet Wild 2, as well as samples of cosmic dust, and return them to Earth for analysis.

Meteoroid embedded in aerogel; the meteoroid is 10 μm in diameter and its track is 1.5 mm long 2008 TC 3 meteorite fragments found on February 28, 2009, in the Nubian Desert, Sudan In 1961, the International Astronomical Union (IAU) defined a meteoroid as "a solid object moving in interplanetary space, of a size considerably smaller than an ...
Dust collector with aerogel blocks as used by the Stardust and Tanpopo missions. Examples of extraterrestrial material collected on Earth include cosmic dust and meteorites. Some of the meteorites found on Earth had their origin in another Solar System object such as the Moon, [1] Martian meteorites, [2] [3] and the HED meteorite from Vesta.
