Nitrogen-Doped Magnetic-Dielectric-Carbon Aerogel for High-Efficiency Electromagnetic Wave Absorption

Nano-Micro Letters, 2023
An ingenious design achieved magnetic-dielectric-carbon coupling. Nickel and manganese oxide particles were in situ reduced and grew on the carbon aerogels. The aerogels demonstrated radar stealth, infrared stealth and thermal management capability.

Chitin Nanowhisker Aerogels [PDF]

ChemSusChem, 2013
AbstractChitin nanowhiskers are structured into mesoporous aerogels by using the same benign process used previously in our group to make cellulose nanowhisker aerogels. The nanowhiskers are sonicated in water to form a hydrogel before solvent‐exchange with ethanol and drying under supercritical CO2 (scCO2). Aerogels are prepared with various densities
