"Silica aerogel is a promising material because its effect is passive," said Kerber. "It wouldn't require large amounts of energy or maintenance of moving parts to keep an area warm over long periods of time." Using modeling and experiments that mimicked the Martian surface, the researchers ...
FT-IR analysis showed that the composite formation of silica aerogel and erythritol were physical, whereas DSC analysis showed that the melting point and heat storage capacity of the composite were 123.8°C and 289.92kJ/kg, respectively. The thermal protection properties of phase change composites ...
c. Aerogel - solvent removed by supercritical extraction Agricultural Uses A hard granular hygroscopic form of hydrated silica is called silica gel. It is made by heating a coagulated sol of sodium silicate. It is used as a catalyst and a desiccant. ...

Silica aerogel, as an example, is prepared by the sol-gel process and has some useful properties, such as ultralow density and low thermal conductivity, even lower than that of free air. This is the result of its mesoporous structure, which allows decreasing the thermal conductivity of ...

Liquid cosmetic composition comprising an oil, hydrophobic silica aerogel particles and a wax with a melting point of greater than 60 DEG C The present invention relates to a liquid cosmetic composition for making up and/or caring for the skin and/or the lips, comprising, in a physiologically ...
Effect of surface modification conditions on the synthesis of mesoporous crack-free silica aerogel monoliths from waterglass via ambient-drying For the successful preparation of crack-free silica aerogel monoliths (disk and tile) at ambient pressure, the effect of surface modification conditions on......
(Todkar et al.2016). Silica nanocomposite can be prepared with rice husk ash, which is used as a nanofiller in epoxy-silica nanocomposites; products display good tensile strength, uniform distribution and no agglomeration (Moosa and Saddam2017). To synthesize high surface area silica aerogel ...
(approximately 0.001–0.003Wm−1K−1in evacuated and opacified conditions depending on temperature) and can even achieve a value of 0.004Wm−1K−1at 50mbar or less making it suitable for VIP applications[25]. Another advantage of Silica aerogel is that it is also considered as non...
