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

Cellulose nanowhisker aerogels
Lindy Heath,Wim Thielemans +1 more
TL;DR: In this paper, a self-assembly of cellulose nanowhiskers in a benign manner was used to produce aerogels with high specific surface areas up to 605 m2 g−1.

A synthetic route to ultralight hierarchically micro/mesoporous Al(III)-carboxylate metal-organic aerogels.
TL;DR: A versatile and facile synthetic route towards ultralight micro/mesoporous metal- organic aerogels based on the two-step gelation of metal-organic framework nanoparticles and the porosity can be readily tuned, leading to the formation of well-ordered intraparticle micropores and aerogel-specific interparticle mesopores, thereby integrating the merits of both crystalline metal- Organic frameworks and light aerogELs.

Inorganic Hollow Nanotube Aerogels by Atomic Layer Deposition onto Native Nanocellulose Templates
TL;DR: It is demonstrated that calcination at 450 °C removes the organic core leading to purely inorganic self-supporting aerogels consisting of hollow nanotubular networks, and the use of a titanium dioxide nanotube network as a resistive humidity sensor with a fast response is demonstrated.

Preparation of silica aerogel using ionic liquids as solvents
TL;DR: Ionic liquids have been used as effective solvents to synthesize aerogels; a long aging time can be used to produce stable aerogel structures without the need for supercritical drying processes as mentioned in this paper.
