The growing demand for sustainable and high-performance materials has driven the need eco-friendly alternatives in coatings polymer industries. This study introduces a novel approach to enhancing epoxy using chitosan-based polycarbamate derivatives synthesized via nonisocyanate route, offering safer more pathway generating isocyanates. successful formation of isocyanate from was confirmed by experimental techniques such as CO2 evolution, TGA, DSC, along with theoretical validation Dmol3 transition state analysis. generated improved mechanical, chemical, thermal properties made diglycidyl ether bisphenol A (DGEBA) triethylenetetramine (TETA). Cure time analysis showed that incorporating chitosan-blocked significantly increased cross-linking density, resulting than twice tensile strength modified films (51 MPa) compared unmodified ones (24 MPa). Additionally, exhibited better flexibility, stiffness, chemical resistance, UV stability, lower surface wettability. system presents scalable, cost-effective solution industries seeking greener protective coatings, adhesives, advanced applications. These findings pave way industrial adoption biobased, materials, promoting environmental sustainability without compromising functionality.

Antimicrobial resistance (AMR) is a major global health problem, exacerbated by the excessive and inappropriate use of antibiotics in human medicine, animal care agriculture. Therefore, new strategies compounds are needed to overcome this issue. In view, it may be appropriate reconsider existing biomaterials alleviate antibiotic overuse. Chitin, naturally abundant amino mucopolysaccharide, poly-β-1, 4-N-acetylglucosamine (GlcNAc). It white, hard, inelastic, nitrogenous polysaccharide source surface pollution coastal areas. Chitosan derives from partial N-deacetylation chitin originates shells crustaceans fungi cell walls. nontoxic natural antimicrobial polymer approved GRAS (Generally Recognized as Safe United States Food Drug Administration). Chitin chitosan, non-toxic biopolymers, useful for wastewater treatment remove pollutants, such pharmaceuticals, heavy metals dyes. The described features make these biopolymers intriguing investigated their application antibacterials.

Endochitinase Chit33 has shown great potential in converting chitin, a recalcitrant waste, into bioactive chitooligosaccharides (COS). This study evaluates how cellulose-binding domain (CBD) and chitin-binding (ChBD) affect the hydrolytic activity product specificity of Chit33. Recombinant proteins were produced isolated with simple yeast extracellular medium concentration. The functionality was proved using chitin cellulose supports. ChBD provided more stable immobilization than CBD but reduced activity. enhanced enzyme on both colloidal (α-/β-allomorphs) crystalline doubling it α-chitin, although not their deacetylated forms. Besides, increased COS production from forms α-/β-chitin (by 30% 85%, respectively) expanded diversity 1 to 9 N-acetylglucosamine units. In contrast, Chit33-ChBD predominantly yielded tetrasaccharides. These findings highlight importance selecting appropriate binding domains tailor specificity, as polymerization acetylation degrees directly impact biological properties.

Fungi chitosan oligosaccharide (C98) crustacean (C95) used as additives. rheological properties determined clear out most suitable temperature processing. In addition, mechanical, thermal, barrier determined. results investigation revealed that PBSA composites 7 wt% 10 C98 additive more films because their higher ultimate elongation values, better damping well superior anti-microbial behavior. However, due lower thermal stability PBSA, processing temperatures desirably should not exceed 120 °C. Additionally, considering decreased moisture vapor properties, it recommended perform further modifications PBSA-C98 through an addition a nanoclay excellent stability.
