Aerogels are highly porous structures prepared via a sol‐gel process and supercritical
drying technology. Among the classes of aerogels, silica aerogel exhibits the most …

Silica aerogel has emerged as a new class of porous solid-state nanomaterials. It consists of
a three‐dimensional (3D) solid silica network with a huge air-filled space of highly cross …

Kistler, in his original definition, stated that aerogels are obtained from gels in which the pore
liquid is replaced by air with moderate shrinkage of the matrix. However, aerogels have …

Monolithic cellulose nanofibrils (CNF)-silica composite aerogels were successfully prepared
by immersing CNF aerogels into a silica solution in a two-step sol-gel process (initial …

Silica aerogels are nanostructured porous solids with an open pore structure, high surface
area, high porosity, low bulk density, and low thermal/electrical conductivity, which have …

Aerogel was a potential substitute for the traditional thermal insulation materials. But
aerogel's fragility and high prices have negative effects on the mechanical property and cost …

Highly porous and hydrophobic silica aerogel is fabricated using fly ash and trona ore as the
starting materials and the cost-effective ambient pressure drying technique. The optimal …

The first step in the preparation of silica aerogels is a sol–gel process producing a gel. This
is followed by drying of the gel by either supercritical drying (SCD) or ambient pressure …

Silica aerogels were prepared using bagasse ash as a silica source through a route
involving the surface modification of wet gels and ambient pressure drying (APD). The silica …

In this paper, we have successfully focused on a hydrophobic silica aerogels synthesis by
the ambient drying of silica gels and the silylation with mono-, di-, and tri-functional agents …
