TL;DR: In this paper, 2D graphene oxide in combination with cationic, anionic, or nonionic polymers were tested for runoff resistance and targeted release behavior in agriculture formulations.
Journal ArticleDOI
Extraction and Physicochemical Characterization of Chitin Derived from the Asian Hornet, Vespa velutina Lepeletier 1836 (Hym.: Vespidae).
TL;DR: The invasive Asian hornet is a promising alternative source of chitin (CHI), based on certain factors, such as the current and probable continued abundance of the quantity and quality of the product obtained.
Journal ArticleDOI
Thermo-responsive behaviors and bioactivities of hydroxybutyl chitosans prepared in alkali/urea aqueous solutions.
TL;DR: Results confirmed the hypothesis that the homogeneous KOH/LiOH/urea aqueous solution is a stable, mild, and energy-saving reaction medium for preparing HBCSs, and displayed antibacterial activities against Staphylococcus aureus and Escherichia coli, thus being suitable for biomedical applications.

Preparation and antibacterial activity of chitosan nanoparticles.
TL;DR: Results show that chitosan nanoparticles and copper-loaded nanoparticles could inhibit the growth of various bacteria tested and exposed to S. choleraesuis led to the disruption of cell membranes and the leakage of cytoplasm.
Journal ArticleDOI
Antibacterial activity of chitosans and chitosan oligomers with different molecular weights.
TL;DR: Antibacterial activities of chitosan was inversely affected by pH (pH 4.5-5.9 range tested), with higher activity at lower pH value, and bactericidal effects with gram-positive bacteria than gram-negative bacteria in the presence of 0.1% chitOSan.
