Summary: Cellulose nanofibrils (CNFs) show promise as reinforcements for polymer fibers, enhancing their strength, stiffness, and fracture toughness. Composite fibers of Poly(methyl methacrylate) (PMMA) and CNFs with varied CNF content were successfully fabricated, leading to significant improvements in mechanical properties. The addition of low-weight fractions of CNFs resulted in increased Young's modulus, yield strength, and fracture toughness in the composite fibers.

Summary: An effective method based on Fe2+ assisted cold plasma was proposed to pretreat pineapple peel cellulose for the preparation of cellulose nanofibrils (CNF). The mechanism underlying Fe2+ assisted cold plasma pretreatment and the resulting changes in cellulose structure were investigated. The results showed that Fe2+ assisted cold plasma treatment significantly decreased the degree of polymerization of cellulose and enhanced electrostatic repulsion of fibrils, leading to the production of CNF. The study provides important insights into developing new pretreatment methods for converting cellulose into CNF.

Summary: Lignin-containing cellulose nanofibrils (LCNFs) with tunable lignin contents were directly prepared from sugarcane bagasse. LCNFs showed a more uniform size and narrow diameter distribution compared to cellulose nanofibrils (CNFs). CNPs made from LCNFs exhibited outstanding mechanical and optical properties, and LCNFs had higher water contact angles than CNFs.

Summary: This study employed various pretreatment methods to prepare cellulose nanofibrils (CNFs) with different pectin composition and content from ramie fibers. The role of residual pectin on the final properties of CNFs was investigated. It was found that the presence of pectin had no significant effect on the size distribution of CNFs, but it led to higher zeta potential value, improved dispersion stability, and enhanced storage modulus of CNF dispersions. The sodium carbonate extraction method showed the greatest impact. The enhanced dispersion stability of CNFs is attributed to the formation of self-assembled hierarchical pectin-hemicellulose/lignin-cellulose nanostructures, which provide electrostatic repulsion and steric hindrance between the nanoparticles.

Summary: In this study, self-standing films of lignin-containing cellulose nanofibrils derived from recycled old corrugated cardboard (OCC) pulp were created. These films exhibited high gas barrier properties, complete UV-shielding ability, and reduced water vapor permeability compared to films made from bleached softwood Kraft (BSK) pulp. The addition of carboxymethyl cellulose improved the predictability of oxygen permeability values in the films. Crosslinking with trivalent aluminum ion or polyamide epichlorohydrin further decreased the oxygen permeability while enhancing the mechanical properties of the films.

Summary: This study investigates the effects of various fibrillation processes on the properties of cellulose nanofibrils (CNFs), including refining, twin-screw extrusion (TSE), ultra-fine grinding, and homogenization. The results show that different processes result in different levels of fiber destructuration and nanofibril property changes. Ultra-fine grinding and homogenization have minimal effects on the mechanical and optical properties of CNFs, while TSE leads to significant decreases in crystallinity index, degree of polymerization, and mechanical properties. Furthermore, the combination of refining and ultra-fine grinding greatly enhances CNF properties, with an increase in optical transmittance.

Summary: This article investigates the effects of CNF and nanosilica containing CNF on ordinary portland cement paste. The presence of CNF can accelerate early age cement hydration, but the effect depends on the water to cement ratio. Addition of CNF can increase the flexural strength of cement paste significantly, but has negligible effect on compressive strength.

Summary: Petroleum-based materials are difficult to degrade and pollute the environment, but cellulose fibrous membranes offer a promising substitute. By constructing biodegradable cellulose fibrous membranes with wood particle fibers and introducing a crosslinking system, the mechanical properties can be enhanced. The addition of cellulose nanofibrils improves the tensile strength and elastic modulus, and the introduction of sodium alginate and Ca2+ further enhances these properties through interpenetrating entanglements and anchors.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
