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

Preparation of TiO2 aerogels by a sol-gel combined solvothermal route
TL;DR: In this paper, the microstructure of the aerogel was studied in detail, showing that aerogels with high surface area exhibited extensive photoluminescent emission at 467, 555 and 615 nm, whose intensity decreased with solvothermal temperature increasing and significantly increased after calcinations.

Constructing secondary-pore structure by in-situ synthesized mullite whiskers to prepare whiskers aerogels with ultralow thermal conductivity
TL;DR: In this paper, the secondary-pore structure formed by the overlapped fibers and whiskers in composite aerogels with secondary pore structure has been discussed and the mechanism of improving thermal stability was discussed in detail.

Robust polyimide nano/microfibre aerogels welded by solvent-vapour for environmental applications.
TL;DR: A new perspective on the simple preparation of nanofibre-based aerogels for air filtration is brought on the basis of electrospun polyimide nano/microfibres used as building blocks to construct hierarchically porous aerogles through a solid-templating technique.
