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

Low-density, transparent aerogels and xerogels based on hexylene-bridged polysilsesquioxane with bendability
TL;DR: Low-density, transparent aerogels based on a hexylene-bridged polysilsquioxane ([O1.5Si]-(CH2)6−SiO1 5] network have been prepared for the first time via a simple sol-gel process as mentioned in this paper.

Perfluoroalkyl bile esters: a new class of efficient gelators of organic and aqueous–organic media
TL;DR: The presence of CO2-philic perfluoroalkyl groups is also expected to enhance their solubility in supercritical CO2 and hence these compounds are promising candidates for making aerogels.
