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.

Numerical modeling of the gas-contributed thermal conductivity of aerogels

TL;DR: In this article, the authors introduced a novel numerical methodology for computing the gas-contributed thermal conductivity of aerogels by analyzing their microstructural characteristics and heat transfer mechanism of the thermal coupling between the gas phase and the solid backbone of the system.

Efficient preparation of crack-free, low-density and transparent polymethylsilsesquioxane aerogels via ambient pressure drying and surface modification

TL;DR: In this paper, a mature technique was applied to modify the surfaces of polymethylsilsesquioxane (PMSQ) gels with terminal silane groups to reduce hydrophilic surface silanol groups without strengthening the skeletons.
