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

Amyloid Templated Organic–Inorganic Hybrid Aerogels
TL;DR: The use of amyloid fibrils as templates for organic-inorganic hybrid aerogels is discussed in this article, focusing on their material synthesis and how the preparation conditions can be tuned to vary the final materials' optical, structural, and mechanical properties.

Synthesis of inorganic aerogels via rapid gelation using chloride precursors
TL;DR: In this paper, the synthesis of silica, titania, zirconia and mixed-metal-oxide aerogels was described by a new facile approach, where low cost and non-toxic chlorides instead of the well established but more expensive and deleterious alkoxy precursors were used as starting materials.

Preparation of super hydrophobic silica aerogel and study on its fractal structure
TL;DR: The experimental results on silica aerogels with super hydrophobic property are reported in this paper, where two-step acid/base process by keeping the molar ratio of tetraethyoxysiliane (TEOS), ethanol (EtOH), water (H 2 O), hydrochloric acid (HCl) and ammonia (NH 4 OH) constant at 1:6:8:1.
