Abstract As a result of the global demand for sustainable products, suitable alternative to resorcinol-formaldehyde aerogels, which are frequently used as precursors carbon is searched for. In this study, replacement petroleum-derived formaldehyde with natural, biobased crosslinker, namely 5-(hydroxymethyl)furfural (5-HMF) shown, and synthesis renewable, monolithic tannin aerogels demonstrated....

By destabilization of quasi-monodisperse silica sols, fractal clusters can be obtained. Solvent evacuation gives a porous solid with fractal structure. Structural investigations of these colloidal aerogels by small-angle neutron scattering are presented, and compared to similar observations in concentrated sols and xerogels. An investigation of the vibrational modes of these materials by inelas...

Carbon-based aerogels have the capability of high adsorption removal copper, lead, and zinc metal ions from water systems.

The toxicity and ecotoxicity effects, handling disposal of synthetic amorphous silica nanoparticles aerogels are reviewed discussed.

The stable Al2O3 aerogels with low density were prepared via template synthesis method using different materials and the as-prepared inherited morphology of materials, which showed network structures. Meanwhile, U(VI) removal on from water was investigated. kinetic analyses indicated that reached equilibrium within 180 min (pH = 7, C0 10 mg/L, m/V 0.1 g/L T 298 K). calculated maximum adsorption...

Controlling protein digestion is a promising strategy to modulate hormonal responses involved in satiety and appetite regulation. In this context, polysaccharide-casein gel-like structures have been developed subjected in-vitro gastrointestinal digestions evaluate their potential for delaying casein hydrolysis. The effect of the polysaccharide type (agar vs. κ-carrageenan), polysaccharide:casei...

The global demand for clean water has become increasingly important in the past decade as a result of growing world population, civilization, and increase sources contaminations. Aerogels are an exceptional form porous materials with extraordinary unique properties. aerogel been fabricated from different inorganic organic incorporated variety novel compounds specific applications to enhance its...
