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

Preparation and photocatalytic performance of magnetic Fe3O4@TiO2 core–shell microspheres supported by silica aerogels from industrial fly ash
TL;DR: In this paper, a ternary magnetic composite of Fe3O4@TiO2/SiO2 aerogel with good photocatalytic activity was prepared successfully by combining sol-gel and simple hydrothermal methods with SiO2 as starting materials, and the structural and magnetic features of the obtained material were investigated by powder X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), transmission electron microscopy (TEM), N2 adsorption-desorption measurements, UV-vis diffuse reflectance spect
