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

Synthesis, structural and chemical properties of iron oxide–silica aerogels
TL;DR: In this paper, an acid-catalyzed solution-sol-gel method combined with subsequent extraction of the alcoholic solvent with supercritical CO2 was used for the sol-gel synthesis of iron oxide aerogels.

TL;DR: A brief overview of the elaboration steps (sol-gel synthesis, aging, and drying), textural and chemical characteristics (aggregation features, porosity, and surface chemistry), the main physical properties (from thermal, mechanical, acoustical, and optical, to biological, medical, etc.), and a rather broad panel of related potential applications of these fascinating nanostructured materials can be found in this article.

Synthesis of conducting polymer hydrogels with 2D building blocks and their potential-dependent gel–sol transitions
TL;DR: Conducting polymer hydrogels with unusual 2D building blocks were synthesized in one step via a combination of oxidative coupling polymerization and non-covalent crosslinking of an amphiphilic thiophene derivative, indicating the occurrence of potential-dependent gel-sol transitions.

Synthesis and characterization of germanium sulfide aerogels
TL;DR: In this article, the synthesis of germanium sulfide gels by thiolysis reactions of a nonaqueous solution of Ge(OEt) 4, followed by supercritical fluid extraction to create aerogels, is described.
