Synthesis and characterization of carbon aerogels with different catalysts
TL;DR: In this article, the structure of carbon aerogels with different catalysts was characterized by scanning electron microscope, transmission electron microscopy and X-ray diffraction, and the specific surface area, pore size distribution and pore volume were measured by surface area analyzer.

Improvement of thermal insulation performance of silica aerogels by Al2O3 powders doping
TL;DR: In this paper, nano-sized Al2O3 powders are explored as nano fillers to reduce the macropore volume fraction in silica aerogels by filling the big voids among the silica aggregates, and further lower the thermal conductivity.

Impact of synthesis conditions on meso- and macropore structures of resorcinol–formaldehyde xerogels
TL;DR: In this article, the effect of different synthesis factors (namely, resorcinol-to-formaldehyde ratio and initial solution pH) on the surface areas, pore volumes, and pore size distributions, and adsorption capacity of liquid nitrogen were studied.

Mechanism and kinetics of nanostructure evolution during early stages of resorcinol-formaldehyde polymerisation

TL;DR: The results indicate that the size of primary clusters appears to be thermodynamically controlled, where a solubility/miscibility limit is reached due to formation of certain reaction intermediates resulting in approximately monodisperse primary clusters, most likely liquid-like, similar toformation of micelles or spontaneous nanoemulsions.

Organic aerogels from the polycondensation of resorcinol with formaldehyde
TL;DR: In this paper, the polycondensation of resorcinol with formaldehyde under alkaline conditions results in the formation of surface functionalized polymer "clusters" which are processed under supercritical conditions to obtain low density, organic aerogels.
