Chitosan–silica composite aerogels: preparation, characterization and Congo red adsorption
TL;DR: In this article, a series of chitosan and/or silica-based aerogels were fabricated by tuning their feeding ratios, which were characterized by FTIR, thermogravimetric analysis, and X-ray diffraction; pore structures were analyzed by Brunauer-Emmett-Teller (BET) nitrogen sorption and scanning electron microscopy (SEM); adsorption capacities to Congo red were explored.

TL;DR: All-organic porous sponges obtained throughout the direct and solvent-free crosslinking of TEMPO-oxidized cellulose nanofibers with 25 kDa branched polyethyleneimine (bPEI) in the presence of different amounts of citric acid (CA) as co-crosslinker showed interesting capability to recover their shape with reduced losses in mechanical resistance, while their Young's modulus progressively increased with the content of CA.
Journal ArticleDOI
Micro-mechanical modelling of cellulose aerogels from molten salt hydrates
TL;DR: The proposed micro-mechanical model is physically motivated and demonstrates a good agreement with the experimental data of both ZnCl2 and Ca(SCN)2 based cellulose aerogels with different cellulose contents.
