Preparation of V2O5 aerogels and aerogel coatings
Journal of Non-Crystalline Solids, 1992Monolithic aerogels and aerogel coatings of hydrated V 2 O 5 , containing up to 10 mol% GeO 2 , were prepared from metal alkoxides by hydrolysis and autoclave drying. The porosity of the monolithic aerogels was > 90%. The aerogels consisted of microfibrous V 2 O 5 polymer.

Aerogels are often largely mesoporous solids, with a porosity which may exceed 90 vol% and a specific surface area up to 1000 m2 g-1. Such materials were first obtained by Kistler in 1932, and designate gels in which the liquid was replaced with a gas without collapsing the gel solid network. Contrary to xerogels dried from wet gels by evaporation with

Research News: Recently listed amongst the top ten scientific and technological developments, aerogels have found applications as traps for relativistic particles, in fire protection and in thermal insulation or acoustic impedance. The materials, which contain more air than gel, their synthesis, and other potential applications are described.

Elastic nonlinearity of aerogels
Physical Review B, 1992We have investigated the sound propagation in ${\mathrm{SiO}}_{2}$ aerogels and three types of organic aerogels: resorcinol formaldehyde, melamine formaldehyde, and vitreous carbon. The main parameter determining the sound velocity is the aerogel density; however, the bond strength and cross linking also influence the stiffness of these materials ...

Versatile Aerogels for Sensors
Small, 2019AbstractAerogels are unique solid‐state materials composed of interconnected 3D solid networks and a large number of air‐filled pores. They extend the structural characteristics as well as physicochemical properties of nanoscale building blocks to macroscale, and integrate typical characteristics of aerogels, such as high porosity, large surface area ...
