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

Assemblies of thiol-capped nanocrystals as building blocks for use in nanotechnology
TL;DR: The assembly of strongly emitting semiconductor nanocrystals can be performed on flat, porous and spherical surfaces and thus are very important for thin-film technologies, doping of mesoporous materials, modification of pre-patterned substrates, the creation of microshells and cavities, etc as mentioned in this paper.

Sol-gel synthesis, porous structure, and mechanical property of polymethylsilsesquioxane aerogels
TL;DR: In this paper, a modified two-step sol-gel process was used to synthesize organic-inorganic hybrid aerogels with polymethylsilsesquioxane (PMSQ, CH3SiO1.5) composition.
