HIGHLY porous inorganic films have potential applications as dielectric materials, reflective
and anti-reflective coatings, flat-panel displays, sensors, catalyst supports and super …

Owing to their ultralow thermal conductivity and open pore structure,–, silica aerogels are
widely used in thermal insulation,, catalysis, physics,, environmental remediation,, optical …

THE preparation of highly porous materials by sol–gel processing followed by supercritical
drying was pioneered by Kistler in 19311. These materials, called aerogels and comprising …

Low-density nanoscale mesoporous composites may be readily synthesized by adding a
colloidal or dispersed solid to an about-to-gel silica sol. The silica sol can “glue” a range of …

Thermal insulation under extreme conditions requires materials that can withstand complex
thermomechanical stress and retain excellent thermal insulation properties at temperatures …

Low density aerogels have numerous unique properties which suggest a number of
applications such as ultra high efficiency thermal insulation. However, the commercial …

In the quest for strong lightweight materials, silica aerogels would be very attractive, if they
were not fragile. The strength of silica aerogel monoliths has been improved by a factor of …

There are many applications for which a material must be water-resistant. Silica aerogels
can have unusual properties, including high surface area, low density, low thermal …

Aerogels are sol-gel derived, supercritically dried materials with porosities up to 98%. The
pore structure extends from scale lengths of about 1 to 100 nm, showing micro-and macro …

We have developed a novel route to monolithic silica aerogels via ambient pressure drying
by the acid–base sol–gel polymerization of methyltrimethoxysilane (MTMS) precursor. An …
