A silica aerogel-based thermal insulation composite film for metal surfaces in gas industries
Silica aerogels are ultralight superinsulators that can increase the efficiency of insulation materials up to three times. In this study, hydrophobic silica aerogels were synthesized using an inexpensive and available water-glass precursor at ambient ...

Absorption capacity, kinetics and mechanical behaviour in dry and wet states of hydrophobic DEDMS/TEOS-based silica aerogels [PDF]
This work is a new approach to the study of the structural, mechanical and absorption properties of hybrid organic/inorganic silica-based aerogels. Diethoxydimethylsilane and tetraethoxysilane have been used as precursors.

Reinforced silica-carbon nanotube monolithic aerogels synthesised by rapid controlled gelation [PDF]
This work introduces a new synthesis procedure for obtaining homogeneous silica hybrid aerogels with carbon nanotube contents up to 2.50 wt.%. The inclusion of nanotubes in the highly porous silica matrix was performed by a two-step sol–gel process ...

Nitrogen sorption as a tool for the characterisation of polysaccharide aerogels [PDF]
Supercritically dried aerogels of several polysaccharides (chitin, chitosan, alginate, alginic acid, k- carrageenan, and agar) have been characterised by physisorption ofN2. Surface areas as high as 570m2 g−1 have been measured.

Bioactivity of wollastonite/aerogels composites obtained from a TEOS-MTES matrix [PDF]
Organic-inorganic hybrid materials were synthesized by controlled hydrolysis of tetraethoxysilane (TEOS), methyltrimethoxysilane (MTES), synthetic wollastonite powders and polydimethylsiloxane (PDMS) in an ethanol solution.
