Novel bioactive materials: silica aerogel and hybrid silica aerogel/pseudowollastonite
Boletín de la Sociedad Española de Cerámica y Vidrio, 2014 Silica aerogel and hybrid silica aerogel/pseudowollastonite materials were synthesized by controlled hydrolysis of tetraethoxysilane (TEOS) using also methanol (MeOH) and pseudowollastonite particles.

Globally Anisotropic High Porosity Silica Aerogels [PDF]
Journal of Non-Crystalline Solids, 2007 We discuss two methods by which high porosity silica aerogels can be engineered to exhibit global anisotropy. First, anisotropy can be introduced with axial strain.

MWCNT/Silica aerogel: Preparation, characterization and applications in heterogeneous catalysis and decolorization of aqueous dye solutions [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2018 2.3 x 10-3 wt% multi-walled carbon nanotube incorporated silica aerogel (MWCNT/Silica aerogel) was synthesized by ambient pressure drying. The as-synthesized MWCNT reinforced silica aerogel was characterized by XRD, SEM, N2-adsorption– desorption, etc.

Silica aerogel core waveguide [PDF]
Optics Express, 2010 We have selectively filled the core of hollow photonic crystal fibre with silica aerogel. Light is guided in the aerogel core, with a measured attenuation of 0.2 dB/cm at 1540 nm comparable to that of bulk aerogel. The structure guides light by different mechanisms depending on the wavelength.

Improvement of Flame Retardancy of Polyurethane Foam Using DOPO-Immobilized Silica Aerogel
Frontiers in Materials, 2021 In this work, silica aerogel was modified by 9,10-dihydro-9-oxa-10-phosphaphenanthrene-1-oxide (DOPO). Then DOPO-immobilized silica aerogel nanoparticles were used as a flame retardant to prepare flame-retardant polyurethane foams.
