Chemical control of the characteristics of Mo-doped carbon xerogels by surfactant-mediated synthesis
TL;DR: In this article, the interaction of molybdate ions (MoO 4 2 - ) with resorcinol-formaldehyde (F) polymerization (RF-gels) was analyzed.

Mechanical and thermal-insulating performance of silica aerogel enhanced jointly with glass fiber and fumed silica by a facile compressing technique
TL;DR: In this paper, a facile compressing approach was presented to prepare glass fiber and fumed silica jointly enhanced silica aerogel composite, which has a high flexural modulus of 2.65 MPa with low thermal conductivity of 0.0226 W/m·K.
Journal ArticleDOI
From hard to rubber-like: mechanical properties of resorcinol–formaldehyde aerogels
TL;DR: In this paper, four types of resorcinol-formaldehyde (RF) aerogels, stiff, brittle, low-flexible, and superflexible are studied.
Journal ArticleDOI
Chemical interactions of surface-active agents with growing resorcinol-formaldehyde gels.
TL;DR: The formation of RF-S copolymers was observed for cationic and nonionic surfactants, but this was not observed for anionic S, probably because of repulsive electrostatic interactions between the two organic phases.
Journal ArticleDOI
Thermodynamic study of adsorption of nickel ions onto carbon aerogels.
TL;DR: The experimental results show that prepared aerogels have an adequate adsorption capacity towards nickel (II) ions and the calorimetric data shows that the greater the area developed in carbons aerogel the enthalpy increases.

Sol-gel science
TL;DR: In this article, the authors present and understand the sol-gel processing sequence from beginning to end, including discussions on the chemistry of hydrolysis and condensation of metal-organics and inorganic salts, the growth of polymeric or particulate species in sols, gelation, aging of gels, drying, structure of Gels, and sintering.

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.
