Before mixing,
aerogel powder and HGM were imaged by a high-resolution SEM (Helios Nanolab 600, FEI).
Donald R Young, president and CEO of Aspen
Aerogels, said, 'Pyrogel HPS is the latest technological advancement to emerge from our
Aerogel Technology Platform.
The bamboo NCF
aerogels were prepared using a freeze-drying method.
Some biogenerated polymers have been also used as active reagents for wastewater treatment, such as starch-derived carbon
aerogels, chitosan, and its derivatives [19, 22].
The researchers suggest that regions of the Martian surface could be made habitable with a material -- silica
aerogel -- that mimics Earth's atmospheric greenhouse effect.
Though
Aerogel Technologies is working with Ford to test lightweight Airloy engine covers with superior sound- and heat-absorption properties, it's the company's work with Airbus that shows the promise of
aerogels in interior applications.
In recent years, for the synthesis of silica based hydrophobic
aerogels tetramethoxysilane (TMOS), tetraethyl orthosilicate (TEOS), polyethoxydisiloxanes, industrial water glass, fly ash, diatomite, bentonite and sodium silicate were used as a silica source [21-28].
Summarizing these studies, the authors obtained macroporous
aerogels that did not exhibit the nanostructure of the corresponding hydrogel.
But until now, removing the water molecules without collapsing the fine silica structure has been a long, difficult and expensive process and, as a consequence, the use of
aerogels has been limited to a few highly specialist tasks.

The spray-dried
aerogels were then transferred into a clean container and labelled accordingly.
In addition to these materials, silica
aerogels firstly synthesized by Kistler in 1931 have been used as additive materials in experimental studies for insulation purposes in concrete technology in recent years.
