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

The influence of composition and porosity on the magnetic properties of FeCo-SiO2 nanocomposite aerogels.
Alberto Casu,Maria Francesca Casula,Anna Corrias,Andrea Falqui,Danilo Loche,Sergio Marras,Claudio Sangregorio +6 more
TL;DR: The magnetic properties of all the nanocomposite aerogels were extensively studied and particular attention was paid to the role played by the interparticle interactions, which are mediated by the silica matrix, in determining the collective magnetic behaviour.

TL;DR: A metal-organic gel based on the new tetracarboxyl ligand N1, N4-(diterephthalic acid)terephthalamide in combination with chromium(III) has been converted into its xero- and aerogel and demonstrated to have excellent specific sorption properties for dyes in its metallogel state, where fuchsine is adsorbed faster than the two other dyes.

Using Nanoscopic Hosts, Magnetic Guests, and Field Alignment to Create Anisotropic Composite Gels and Aerogels
TL;DR: In this paper, anisotropic composite architectures of vastly different length scales are organized upon nanogluing magnetic microparticulate guests (ca. 10−15 μm iron powder) into a guest−host network by gelation of silica sol in the presence of an externally applied magnetic field.
