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

Fabrication of Macro-Mesoporous Zirconia-Alumina Materials with a One-Dimensional Hierarchical Structure
TL;DR: In this article, a series of one-dimensional (1D) zirconia/alumina nanocomposites were prepared by the deposition of Zirconium species onto the three-dimensional framework of boehmite nanofibers formed by dispersing boebers into butanol solution, and the materials were calcined at 773 K and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), TEM, N2 adsorption/desorption, and infrared emission spectroscopy (IES).

Electrochemical co-deposition of sol–gel/carbon nanotube composite thin films for antireflection and non-linear optics
Liang Liu,Liang Liu,Shai Yellinek,Noam Tal,Reut Toledano,Ariela Donval,D. Yadlovker,Daniel Mandler +7 more
TL;DR: In this paper, the authors showed that the electrodeposited sol-gel/CNT composite films have non-linear optical properties and exhibit pronounced antireflective performance (specular reflection < 0.5%) over a visible to long-wave IR range.
