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

Zirconia Aerogels with High Surface Area Derived from Sols Prepared by Electrolyzing Zirconium Oxychloride Solution: Comparison of Aerogels Prepared by Freeze-Drying and Supercritical CO2(l) Extraction
TL;DR: In this paper, the microstructures and properties of aerogels produced by the two processes were compared and the effects of yittria on the microstucture and phase structure of the prepared aerogel were investigated.

Formation of Polycyanoacrylate-Silica Nanocomposites by Chemical Vapor Deposition of Cyanoacrylates on Aerogels
TL;DR: In this article, the first CVD reinforcement of silica aerogels using cyanoacrylates was reported, which resulted in a 32× improvement over native silica Aerogels while not diminishing the aerogel's attractive physical properties.
