TLDR
The design of such a filigrane network requires the very careful control of chemical parameters and the reward is an assortment of different property profiles owing to the richness of possible variations.Abstract:
Air, air, air… and some solid skeleton; this is the basis for an interesting class of materials-the aerogels (shown schematically on the right). Can one therefore speak of "simple" chemistry? The design of such a filigrane network requires the very careful control of chemical parameters. The reward is an assortment of different property profiles owing to the richness of possible variations.read more

Ambient-pressure drying synthesis of large resorcinol–formaldehyde-reinforced silica aerogels with enhanced mechanical strength
TL;DR: In this paper, a facile sol-gel route was developed to fabricate a large (500 cm3) polymer-silica aerogel monolith that was stable under atmospheric conditions and suitable for machining.

Structure and Thermal Conductivity of Silica Aerogels from Computer Simulations
TL;DR: In this article, the authors investigate the relationship between the structure of the gels, their dimensionality and density, and their thermal conductivity, and find evidence for a transition from fractal behavior at small length scales to approximately compact behavior at larger lengths.

Lead Selenide Nanostructured Aerogels and Xerogels
TL;DR: In this article, the synthesis of PbSe nanostructured gels via a sol-gel nanoparticle assembly method, followed by CO2-supercritical drying to make aerogels is reported.

Correlation between heparin release and polymerization degree of organically modified silica xerogels from 3-methacryloxypropylpolysilsesquioxane
TL;DR: It was demonstrated that higher drug loads and a decreasing polymerization degree resulted in a faster release profile of heparin, which followed a square root of time kinetic according to the Higuchi model.
