Transparent matrices of low refractive index are promising carriers for photoluminescent nanoparticles targeting true volumetric 3D display applications. Complementation of transparency with a highly open-porous nanomorphology renders respective hybrid gels and aerogels additionally attractive for liquid and gas detection devices. Herein, we present virtually fully bio-based hybrids obtained by decorating...
Cellulose nanofibers (CNFs) are becoming a topic of great interest due to their wide range of potential applications. The huge presence of carboxylic groups in TEMPO-oxidized CNFs indicate that this material could interact with cationic species in aqueous solution, such as metal ions. Nevertheless, the contact between nanofibers and water solutions requires a 3D structure to entrap and retain the...
In this paper, we reported a facile and eco-friendly approach for the synthesis of new type multifunction cellulose nanofibers-graphene aerogel (CGA) by hydrothermal processing, freeze-drying and carbonization. Then we explored its energy and environmental applications as supercapacitors electrode and absorbents. The results showed that the prepared CGA possessed highly porous and interconnected three-dimensional...
Spilled oil in seas has a direct impact on the environment and biodiversity. Moreover, there is no clear relationship between the amount of oil in the aquatic environment and its impact, since it mainly depends on the time and season that the oil is spilled. Nowadays, there are several techniques to clean up and recover oil from the sea, including the use of microorganisms, chemicals, controlled burning,...
Chemical vapor deposition of a thin titanium dioxide (TiO2) film on lightweight native nanocellulose aerogels offers a novel type of functional material that shows photoswitching between water‐superabsorbent and water‐repellent states. Cellulose nanofibrils (diameters in the range of 5–20 nm) with native crystalline internal structures are topical due to their attractive mechanical properties, and...
