Highly Charged Cellulose Nanocrystals Applied as A Water Treatment Flocculant.
TL;DR: The quaternary agent 3-chloro-2-hydroxypropyltrimethylammonium chloride was used as a cationic graft on CNCs, to form a novel water treatment flocculant, demonstrating a natural and environmentally sustainable alternative to homologous commercialFlocculants.
Valorization of Garlic Crops Residues as Precursors of Cellulosic Materials
TL;DR: In this article, the authors evaluated residues of garlic crops from Colombia, as promising sources of cellulosic materials, and demonstrated an efficient re-engineering of the waste products to highly valuable cellulose materials as precursors of cellulose derivatives suitable for functionalization.
