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

Spontaneous preparation of hierarchically porous silica monoliths with uniform spherical mesopores confined in a well-defined macroporous framework
TL;DR: The as-prepared silica monolith possesses an interesting hierarchically porous structure constructed by 10 nm uniform spherical mesopores confined in a macroporous framework of well-defined 1 μm macropores, and exhibits a BET surface area as high as 848 m(2) g(-1).

Porous organic–inorganic hybrid aerogels based on bridging acetylacetonate
TL;DR: In this article, a novel type of organic-inorganic hybrid aerogels with high micro- and mesoporosity have been prepared successfully from a bridging bis(acetylacetonate) ligand, 3,4-diacetyl-2,5-dioxohexane, and trivalent metal ions (Al3+ and Cr3+).
