A representative surfactant, benzalkonium chloride (BAC) is used as a disinfectant, but sometimes causes serious side effects, including lung disorders such as interstitial pneumonia. However, its pathogenic mechanisms remain unexplained. In this study, we identified a novel mechanism by which BAC initiates inflammatory responses that may be responsible for its side effects.

In this study, demethylated-acylated enzymatic hydrolysis lignin (DAEHL) with excellent solubility in castor oil and antioxidant activities were prepared via the tandem modification strategy. First, iodocyclohexane simultaneously achieved β-O-4 breakage and hydrogenation, which enhanced the antioxidant activity of lignin. Furthermore, the acylation reaction by palmitoyl chloride increased the alkyl content in the lignin, which can improve the solubility of lignin in castor oil.

Two novel complexes, [Cu()Cl] and [Zn()Cl], were synthesized from 1,1'-[(3-fluoro-phen-yl)methyl-ene]bis-[3-(3-fluoro-phen-yl)imidazo[1,5-]pyridine] (), and copper(II) and zinc(II) chloride, respectively. The structures of these complexes were confirmed using ESI-MS, IR and H NMR spectra. The results reveal mononuclear structures in which the central metal atoms are coordinated by two N atoms from the imidazole rings and two Cl ligands.

Industrialization of military textiles faces many challenges and some requirements such as durability, protection and suitability for hostile environment must be provided. Herein, fluorescent protective cotton with ultraviolet radiation (UVR)-protection and antimicrobial property was currently prepared via the immobilization of lanthanide-metal organic framework (Ln-MOF). Cotton fabrics were primarily activated via cationization process with 3-Chloro-2-hydroxypropyltrimethyl ammonium chloride to obtain the cationized cotton (Q-cotton).

Ice formation poses a significant challenge across various fields, from industrial processes to biological preservation. Developing antifreeze agents and recognizing the antifreeze mechanism have gained considerable attention. Herein, a series of poly(l-methionine) derivatives, poly(-carboxymethyl-l-methionine sulfonium) (PMetA), poly(-methyl-l-methionine sulfonium chloride) (PMetM), and poly(-carbamidomethyl-l-methionine sulfonium chloride) (PMetAM), with carboxyl, methyl, and acetamide groups, respectively, are synthesized and investigated for antifreeze.
