This review is focused on describing the intimate link which exists between aerogels and
thermal superinsulation. For long, this applied field has been considered as the most …

Silica or various silicate aerogels can be characterized by highly porous, open cell, low
density structures. The synthesis parameters influence the three-dimensional porous …

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 …

Silica aerogels are unique solids with extremely high porosity, transparency and low density.
They make excellent adsorbing materials due to their high surface area and three …

We report a method to synthesize low-density transparent mesoporous silica aerogel beads
by ambient pressure drying (APD). The beads were prepared by acid–base sol–gel …

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 …

Aerogels are three-dimensional nanostructures of non-fluid colloids connected to porous
networks made of loosely packed bonded particles. They are often manufactured utilizing …

In this paper, we report experimental results on the synthesis of low-density
tetraethoxysilane (TEOS)-based silica aerogels prepared with different solvents via an …

Inorganic silica aerogels derived from sodium silicate are voluminous three-dimensional
open networks with exceptional properties such as a density as low as∼ 100 kg m− 3, high …
