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

Highly Active ZnO-ZrO2 Aerogels Integrated with H-ZSM-5 for Aromatics Synthesis from Carbon Dioxide
TL;DR: Bifunctional catalysis coupling CO2 to methanol and methanoline to hydrocarbons is a promising strategy for the direct hydrogenation of CO2 into high-value chemicals.

Spray freeze-dried nanofibrillated cellulose aerogels with thermal superinsulating properties.
TL;DR: Nanofibrillated cellulose aerogels prepared by spray freeze-drying showed a fibril skeleton morphology, which defines a mesoporous structure, making them one of the best cellulose based thermal superinsulating material.

Preparation of novel whey protein-based aerogels as drug carriers for life science applications
TL;DR: In this paper, a comparative study of the properties of the resulting whey protein aerogels and cryogels was carried out, and the use of whey proteins as carriers for active compounds was assessed using ketoprofen as the model drug.

Advances in switchable and highly insulating autonomous (self-powered) glazing systems for adaptive low energy buildings
TL;DR: In this paper, the authors present a review of the state-of-the-art glazing technologies for controlling solar heat gain and low heat loss in building facades, including the use of multiple glass panes or aerogels, and inert gas or vacuum between the panes to reduce or eliminate convective heat transfer.

Strong, Thermally Superinsulating Biopolymer–Silica Aerogel Hybrids by Cogelation of Silicic Acid with Pectin
Shanyu Zhao,Wim J. Malfait,Arnaud Demilecamps,Yucheng Zhang,Samuel Brunner,Lukas Huber,Philippe Tingaut,Arnaud Rigacci,Tatiana Budtova,Matthias M. Koebel +9 more
TL;DR: A one-pot process to monolithic, superinsulating pectin-silica hybrid aerogels is presented and the change in the mechanical properties is directly linked to the observed "neck-free" nanoscale network structure with thicker struts.
