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

Novel flexible aerogels derived from methyltrimethoxysilane/3-(2,3-epoxypropoxy)propyltrimethoxysilane co-precursor
TL;DR: In this article, flexible aerogels from methyltrimethoxysilane (MTMS) and 3-(2,3-epoxypropoxy)propyltrimethyltrimethyltropoxy (GPTMS) were obtained by employing a two-step acid-base sol-gel process along with the use of a surfactant.

Experimental Characterization of the Thermal Conductivity and Microstructure of Opacifier-Fiber-Aerogel Composite.
TL;DR: The pore size distribution indicates that the volume fraction of the micropore and mesopore is also the key factor for reducing the thermal conductivity of porous materials, which proves that the proper type and moderate content of opacifier dominates the low thermalonductivity.

Zeolite/silica aerogel composite monoliths and microspheres
TL;DR: In this article, a series of silica aerogels and composite materials based on Fe-silicalite-1 nanocrystals embedded into a Silica Aerogel matrix in the form of monoliths and microspheres have been synthesized by drying with supercritical CO2.

Heterogeneous silica-polyimide aerogel-in-aerogel nanocomposites
Wim J. Malfait,OG0-093-pdf-dumps +1 more
TL;DR: The aerogel-in-aerogel composites as discussed by the authors are a promising, non-brittle alternative to silica aerogels, but are limited by their very poor high-temperature stability.
