Abstract Lignin (Lg) fractionation overcomes the limitations of its heterogeneous nature. In this study, effect methanol on thermal degradation, crystallinity, morphology, and chemical structure lignin application in hydrogen peroxide sensing are investigated. Pristine Lg was separated into low‐molecular‐weight (LMwLg) high‐molecular‐weight fractions (HMwLg), followed by modification to hydroxymethyl (HmLg), which reduced silver ions solution nanoparticles (AgNPs). The functional groups, profile, morphology were then investigated using Fourier transform infrared spectroscopy, powder diffraction, gravimetry, scanning electron microscopy. LMwLg found be crystalline, highly hygroscopic, had four degradation stages, while HMwLg several stages amorphous. sharp peaks diffractogram characteristic sodium ions, those AgNPs‐HmLg AgNPs, as evidenced SPR peak at 428 nm whose intensity decreased presence peroxide.

Processing lignin into nanoparticles (LNPs) offers a promising utilization strategy; however, its structural and molecular weight heterogeneity poses challenges in the formation of uniform LNPs. In this study, industrial kraft was fractionated stepwise (Mw) from low to high which LNPs were fabricated via antisolvent precipitation. The results showed that with Mw benefits smaller-sized Particularly, fraction 2016 g·mol–1 fails form main mechanism is higher content hydrophilic groups (mainly phenolic hydroxyl groups) on lower hinders This hypothesis supported by successful homogeneous after acetylation. Fractionation effectively reduces promotes LNPs, would favor chemical reactivity properties, enhancing lignin.

Abstract Trees, consisting of leaves, trunks, etc., efficiently eliminate gaseous pollutants and serve as an indispensable air purification system for Earth. In this study, lignin from trunks phytol leaves are co‐assembled into macroporous nanospheres with high efficiency scavenging reactive oxygen species (ROS) harmful gases, which integrated cigarette filters lung protection. The alkyl chains disrupt the π–π stacking in lignin, forming pore throats that expand 0 to 120 nm content increases. Consequently, higher levels anchored phytol, greater antioxidant capacity co‐assemblies. subsequently loaded filters, each gram porous nano‐lignin capable treating ≈100 standard cigarettes. ROS can reach up 97%, effectively removing gases like carbon monoxide formaldehyde, outperforming existing filters. a mouse model, containing these microscopic purifiers significantly suppressed inflammation provided notable tissue This study presents robust non‐covalent method is both straightforward efficient, enabling rapid application plant extracts highly effective sustainable filter materials.

This study employs a combined computational and experimental approach to elucidate the mechanisms governing interaction between lignin urea, impacting dissolution subsequent aggregation behavior. Molecular dynamics (MD) simulations reveal how urea concentration temperature influence conformation interactions. Higher concentrations temperatures promote dispersion by disrupting intramolecular interactions enhancing solvation. Density functional theory (DFT) calculations quantitatively assess energy supporting findings from MD simulations. Anti-solvent precipitation demonstrates that increasing hinders self-assembly of nanoclusters. The provide valuable insights for optimizing biorefinery processes tailoring efficient extraction dispersion. Understanding on behavior opens up avenues designing novel lignin-based materials with tailored properties. highlights potential synergetic application DFT unravel complex material at atomic level.
