Chemistry of Aerogels and Their Applications
Alain Pierre,Gerard Pajonk +1 more
TL;DR: Aerogels form a new class of solids showing sophisticated potentialities for a range of applications, and can develop very attractive physical and chemical properties not achievable by other means of low temperature soft chemical synthesis.

Electrically conductive oxide aerogels: newmaterials in electrochemistry
Debra R. Rolison,Bruce Dunn +1 more
TL;DR: Aerogels, which are nanoscale mesoporous materials of low density and high surface area, have been well studied as thermal insulators, heterogeneous catalysts, and novel particle or radiation detectors as mentioned in this paper.

Aerogels in catalysis
M. Schneider,Alfons Baiker +1 more
TL;DR: In this paper, a solution-sol-gel (SSG) method was used for aerogel preparation and their subsequent liberation from the solvent via critical-point drying or supercritical (or hypercritical) drying (SCD).
Journal ArticleDOI
Sol—Gel preparation of supported metal catalysts
TL;DR: In this paper, the synthesis conditions of supported metal catalysts using sol-gel method are reviewed, and potential applications of these materials are presented with emphasis on: thermally resistant materials, catalysts with low deactivation rates, high surface area materials and catalytic membrane reactors.

TL;DR: In this article, a filigranes Netzwerks bedarf einer auserst genauen Kontrolle und Einstellung der chemischen Parameter, dank der Reichhaltigkeit der Variationsmoglichkeiten wird man dann aber mit einer Vielfalt von unterschiedlichen Eigenschaftsprofilen belohnt.

Coherent Expanded-Aerogels
TL;DR: The two-phase structure of gels has been investigated extensively in colloid chemistry as discussed by the authors, and the results of diffusion experiments through gels, the fact that the electrical conductivity, refractive index, and vapor pressure before and after setting are identical, at least in certain cases, and the known facts of syneresis would seem to leave little room for doubt of the two phase nature of Gels in general.
Journal ArticleDOI
Inorganic oxide aerogels
TL;DR: In this paper, a method of preparation of aerogels of SiO2, Al2O3, TiO2 and mixed oxides has been developed, which does not require the purification of the precipitated metal oxide nor the substitution of an organic solvent for water which is the case when the formation of the initial gel is carried out in water medium.
