Preparation, Characterization, and Applications of Nanosponges: A Review

Introduction Nanosponges (NSs) are nanosized, highly porous, cross-linked polymeric structures capable of entrapping guest molecules via inclusion and non-inclusion interactions. Cyclodextrin-based nanosponges (CD-NSs) — obtained by crosslinking native or modified cyclodextrins — are the most widely studied class because of the innate biocompatibility and inclusion ability of cyclodextrins. Between 2010 …

Adsorption of Caffeine onto Fique Bagasse Biochar Generated at Various Pyrolysis Temperatures

 Introduction Caffeine is a widely detected anthropogenic micropollutant in surface and wastewater systems due to human consumption and incomplete removal in conventional treatment systems. Adsorption onto low-cost carbonaceous materials has been widely studied as an effective tertiary treatment step. Biochar derived from agricultural residues combines low-cost feedstock with tunable surface …
