Summary: Amine-modified silica aerogel was synthesized as an efficient and environmentally friendly adsorbent for removing nanoparticles. Doping with 3-aminopropyltriethoxysilanes enhanced the adsorption capacity, making it 19 times more efficient than unmodified aerogel. The study provides a reliable adsorption approach for nanoparticle removal and investigates the intricate adsorption mechanism.

Summary: Hierarchical systems combining structural glass fibers with a bi-continuous silicabased aerogel matrix demonstrate significant improvements in mechanical properties, with up to 27% increases in compressive strength and interlaminar shear strength without any loss in modulus. The bicontinuous network modification strategy uses industrially-relevant infusion techniques and retains a similar final composite density (within 2%). This strategy offers a versatile and readily applicable means to enhance continuous fiber reinforced composite systems in compression and provides an opportunity for the development of new composite materials.

Summary: In this study, a high-efficiency carbon aerogel (SCA) derived from sericin waste was used to improve the adsorption efficiency of oils and organic solvents. The SCA exhibited excellent sorption capacity for soybean oil, chloroform, and methylene chloride. It could also be regenerated multiple times without significant loss in adsorbability. Scanning electron microscopy (SEM), Brunauer-EmmettTeller (BET), X-ray diffraction (XRD), Raman spectra, and Fourier transform infrared spectroscopy (FTIR) analysis confirmed the physical and chemical characteristics of SCA. The results suggest that SCA is an effective adsorbent for oils and organic solvents, contributing to the reduction of sericin-containing wastewater discharge and alleviating pollution caused by oil and organic solvent leakage.

Summary: This study presents a carbon nanotube-based aerogel with a flexible-rigid core-shell structure, which exhibits a combination of superelasticity, high strength, and wide tunability. The flexible carbon nanotube cores ensure the integrity of the skeleton, while the outer rigid carbon shells crosslink the cores and crack into orderly distributed segments during compression. This designed aerogel shows superior mechanical properties compared to previous foams/aerogels, and has potential applications in pressure sensors and energy absorbers.

Summary: This work presents a facile approach to prepare cellulose/MWCNTs hydrogels and aerogels by mixing cellulose with N, N'-methylene bisacrylamide (MBA) and MWCNTs in NaOH/urea/H2O aqueous solution. The hydrogels exhibited shorter gelation time, higher puncture strength, and water retention ability compared to pure cellulose hydrogel. The cellulose/MWCNTs aerogels possessed a three-dimensional network structure with a macroporous structure, low density, high porosity, good thermal stability, and certain absorbency to methylene blue.

Summary: This study focuses on the synthesis of silicon-containing polyarylacetylene (PSA) resin, which enhances the heat resistance and mechanical properties of polymer reinforcement phase. The honeycomb-like porous SiO2/PSA aerogels, prepared through click reaction, gel aging, freeze-drying, and curing, possess low density, high porosity, low thermal conductivity, and excellent thermal insulation performance. Compared to other polymer aerogels and materials, SiO2/PSA composite aerogel exhibits high temperature resistance, compressive strength, and has potential applications in the aerospace industry.
