Successful tissue remodeling following biomaterial implantation requires adequate tissue integration, which is often compromised by macrophage-mediated foreign body responses and persistent inflammation. Developing biomaterials that actively modulate macrophage behavior via biophysical and biochemical cues holds significant promise for tissue engineering. Here, we present a magneto-actuated polyelectrolyte scaffold platform, where antioxidative lignin@Fe3O4 nanoclusters are noncovalently anchored onto chitosan/chondroitin sulfate scaffolds. Upon exposure to a dynamic magnetic field, the nanoclusters generate interfacial microvibrations, delivering dynamic mechanical stimuli to macrophages while simultaneously scavenging reactive oxygen species via their intrinsic antioxidative activity. This mechano-chemo coordinated modulation effectively induces macrophage polarization from the M1 to M2 phenotype, as evidenced by significantly downregulated pro-inflammatory markers and upregulated anti-inflammatory markers in vitro. As a proof of concept, the subcutaneous implantation of scaffolds under the dynamic magnetomechanical actuation demonstrates improved tissue integration, characterized by reduced inflammation and enhanced extracellular matrix deposition. This platform offers an approach for promoting biomaterial adoption and tissue remodeling through spatiotemporally coordinated mechano-chemo modulation.

Owing to the growing interest in lignin-derived hybrid fillers for biomass valorization and sustainable rubber applications, molecular engineering of lignin has emerged as an effective strategy. This work designed a versatile organic–inorganic nano-hybrid via the in-situ assembly of quaternized lignin (Q n L) and SiO 2 . Lignin was first quaternized yielding a series of Q n L with tunable grafting content (4.40–17.95 wt%). Driven by electrostatic interactions, Q n L and SiO 2 assembled into shell-core structured nanohybrids (Q n LSi), exhibiting a denser packing morphology and higher hydrophobicity compared to the unmodified lignin/SiO 2 reference. These structural characteristics promoted uniform dispersion of hybrid particles when incorporated into styrene-butadiene rubber (SBR) via latex mixing. The hybrids with a higher degree of lignin quaternization enabled the SBR vulcanizates to achieve improved vulcanization efficiency ( t 90 reduced from 21.90 to 13.16 min), enhanced mechanical properties (tensile strength increased from 24.2 to 29.5 MPa) and reduced dynamic losses (tan δ 60 °C decreased from 0.111 to 0.104). This superior performance stems from the small particle size, favorable surface functionalities and strong rubber-filler affinity. Overall, this study highlights the molecular engineering strategy to shape lignin into multifunctional hybrids for high-performance, energy-efficient, and sustainable rubber materials.

Conventional biodiesel production relies on external heating, requiring high temperatures and strict control over system water content. This work prepared a magnetic lignin-based heterogeneous acid catalyst Fe 3 O 4 -LS/100-Al using sodium lignosulfonate as support via co-precipitation and impregnation, with Lewis acid sites, and applied it in electrolysis-assisted esterification for biodiesel. The catalyst showed a specific surface area of 115.63 m 2 /g and saturation magnetization of 29.98 emu/g, enabling efficient acid loading and rapid magnetic separation. Under RSM-optimized conditions (catalyst of 6.8 wt%, MOAMR of 12.5:1, voltage of 45.4 V, water content of 4.7 wt%), oleic acid conversion reached 95.25%. Low activation energy (36.04 kJ/mol) confirmed high catalytic activity, and 71.38% conversion was retained after seven cycles. Results prove electrolysis assistance enables efficient, ambient-temperature biodiesel synthesis.

To advance the high-value utilization
of lignin and develop
sustainable
materials for clean energy applications, a fully bioderived polyimine
vitrimer (VL) was synthesized through an energy-efficient room-temperature
process by covalently integrating levulinic acid-modified lignin with
a soybean oil-derived diamine. This design yields a material that
combines robust mechanical properties (toughness: 7.1 MJ/m 3 ) with remarkable self-healing, recycling, and photothermal conversion
capacities. The vitrimer can repair scratches within 10 min at 80
° C and can be fully recycled with ∼90% strength retention
after five reprocessing cycles. These dynamic features are governed
by the cooperative exchange of hydrogen and imine bonds. Furthermore,
the material demonstrates stable and efficient photothermal conversion,
a direct result of the preserved π-conjugated and donor–acceptor
structure of the lignin units. This photothermal capability not only
enables applications such as photothermoelectric generation but also
permits noncontact, light-triggered self-healing. This work transforms
lignin from a byproduct into a core building block for advanced smart
materials, providing a sustainable paradigm for developing multifunctional
systems in energy and wearable technologies.

The deoxygenation and alkylation reactions during the co-pyrolysis of lignin and SBC were investigated. • Mo-doped biochar increased alkylphenols selectivity from 6.5% to 33.0%. • In-situ DRIFTS and DFT calculations were used to investigate the pyrolysis mechanism. • The electron-donating effect of methoxy groups facilitated the adsorption of methoxyphenols onto the catalyst. • The formation mechanism of alkylphenols was proposed. Lignin pyrolysis is a sustainable pathway for synthesizing high-value alkylphenol chemicals and fuels. In this study, the co-pyrolysis process of lignin and spent bleaching clay was investigated for producing alkylphenols. The effects of different metal-loaded biochars, pyrolysis temperatures, and lignin-derived phenolic compounds on the distribution of pyrolysis products were examined. The results showed that the total acid content in Mo/C was 3.39 times higher than that in the pristine carbon. Additionally, Mo/C exhibited the highest number of weak acid sites (56.0%), abundant surface oxygen-containing functional groups, and a microporous structure. These characteristics facilitated both the cleavage of methoxy groups (C Ar –OCH 3 ) and the occurrence of aromatic C–C coupling reactions, thus increasing the selectivity of alkylphenols from 6.5% to 33.0%. Alkylphenol yield peaked at 500°C, whereas higher temperatures favored demethoxylation over coupling. Methoxyphenol exhibited an approximately 20–25% higher alkylation rate than phenol. Electrostatic potential calculations attributed this enhancement to the electron-donating effect of the methoxy group, which facilitated its attack by electrophilic alkyl fragments. In-situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) revealed the anchoring of phenolic intermediates on the Mo/C surface through Mo–O bonds. Charge difference calculations revealed electron transfer between the oxygen-containing functional groups of phenolic compounds and the Mo/C catalyst, thereby activating the C–O bond. Alkylphenols were generated through two distinct pathways: the deoxygenation of methoxyphenols and the coupling reaction between phenol and alkyl fragments. The deoxygenation pathway was more energetically favorable. This study provides insight into the low-cost and efficient production of green alkylphenol compounds.

The efficient hydrodeoxygenation (HDO) of lignin oil to produce high-value-added cycloalkanes is a key route for biomass resource utilization. However, developing catalysts with both high catalytic activity and product selectivity remains a crucial challenge in this field. Herein, a strategy integrating crystalline-phase regulation and hydrogen spillover was proposed. Ru was doped into the ZIF-67 precursor via a one-pot method. After controlled calcination and hydrogen reduction, a nitrogen-doped carbon-coated Ru-Co bimetallic catalyst (RuCo@NC) was successfully prepared. Characterization results showed that the introduction of Ru induced the phase transformation of Co from face-centered cubic (FCC) to hexagonal close-packed (HCP) and precisely regulated the electron density distribution of catalytic active sites through Ru to Co electron transfer. H 2 -TPR/TPD confirmed that Ru, as a hydrogen spillover site, significantly enhanced low-temperature reducibility and hydrogen adsorption capacity. DFT calculations indicated that Ru sites dominated the efficient dissociation and activation of H₂ molecules, while Co sites were responsible for the selective adsorption of substrate molecules. The synergistic effect between the two metals greatly improved the HDO activity of the catalyst. The optimized 0.009RuCo@NC-400 catalyst achieved 100% conversion of lignin oil at 240 °C and 2 MPa H₂, with a cycloalkane selectivity of 73.7%. Moreover, the conversions of ten lignin derivatives were all above 97%. This study reveals a synergistic catalytic mechanism of the 0.009RuCo@NC-400 catalyst, integrating crystalline phase structure, electronic effects, and hydrogen spillover, providing theoretical guidance for the design of efficient HDO catalysts.

The emergence of 5G technologies and advanced high-power electronics demands urgently thermal interface materials (TIMs) with superior thermal transport properties for efficient heat dissipation and reliable thermal management. However, existing TIMs suffer from unsatisfactory interfacial heat transfer efficiency due to the inherent trade-off between achieving high thermal conductivity and excellent viscoelasticity. Here, drawing inspiration from wood supramolecular architectures, a viscoelastic thermally conductive plasticine (AL-VTCP) is fabricated via alkali lignin (AL)-induced supramolecular self-assembly, integrating phase change emulsions with boron nitride nanosheets for nanoscale thermal regulation. Attributed to AL-induced dynamic supramolecular interactions, the developed AL-VTCP not only enhances viscoelastic properties and reduces contact thermal resistance by 71.9%, but also optimizes the thermal conductivity pathway, resulting in an 18.8% increase in thermal conductivity compared with VTCP. Consequently, combined with phase-change heat absorption, a CPU device with AL-VTCP achieves an additional temperature reduction of approximately 13.1 °C compared to high-performance commercial TIMs. Additionally, AL-VTCP demonstrates a low compression modulus (170 kPa), excellent interface adaptability, and minimal environmental impact. This work demonstrates the molecular level engineering of TIMs that optimizes heat transport while minimizing interface resistance, enabling advanced electronics thermal management in 5G integrated systems. Graphical abstract In this work, inspired by wood supramolecular architectures, we fabricate a viscoelastic thermally conductive plasticine (AL-VTCP) via alkali lignin-induced supramolecular self-assembly. The interfacial design simultaneously enhances thermal conductivity and viscoelasticity, thereby solving inherent contradiction and enabling superior heat dissipation capabilities. This work demonstrates the molecular level engineering of TIMs optimizing thermal transport while minimizing interfacial resistance, enabling advanced electronics thermal management in 5G integrated systems.

Combustion is one of the main sources of particulate matter (PM) emission during the biomass utilization, while the effects of three components, namely cellulose (CL), hemicellulose (HC), and lignin (LG), are still unknown. In this work, the model compounds were used to simulate the three components of cornstalk (CS), and their interactions on the PM emission behavior during the individual or co-combustion were investigated. Meanwhile, three different potassium-containing compounds were introduced to simulate the reactions between three components and alkali metals. The results showed all particle size distribution curves from the combustion of three components exhibited a unimodal distribution, while CS presented a bimodal distribution. The total PM 10 yields from the combustion of CL, HC, and LG are 0.32, 0.65, and 5.27 mg/g_fuel, much lower than that from cornstalk combustion (10.04 mg/g). The interaction between CL and HC could facilitate the formation of PM 0.1 and increase its yield by 4.93%. In contrast, the interaction between HC and LG was conducive to reducing PM 1 by 13.2%. However, the interaction between CL and LG has little impact on PM emission. The types of potassium salts had a significant impact on PM formation, and K 2 SO 4 , CH 3 COOK, and KCl could inhibit the PM emission, achieving a 9.4%–13% reduction compared to the theoretical value.

The ultraviolet (UV) shielding properties of food packaging materials have garnered significant attention for mitigating issues such as off-flavors, discoloration, and nutrient degradation. However, achieving effective UV protection while maintaining sustainability and performance in packaging materials remains a challenge. Herein, a novel multifunctional composite coating with UV-shielding properties was prepared using cellulose nanocrystals (CNCs) and sodium lignosulfonate (SL) as functional components and polyvinyl alcohol (PVA) as a cross-linking agent. Notably, the SL-4/C/P coated paper prepared using the coating with an SL/CNCs mass ratio of 4:1, exhibited excellent UV-shielding efficiencies (98 % shielding in the UVA region and almost completely block the whole UVB region), enhanced mechanical properties (126 % increase in tensile index and 308 % improvement in folding endurance), lower Cobb 30 value (decreased from 66 g/m 2 to 56 g/m 2 ), and reduced air permeability (decreased from 124 mm/s to 52 mm/s) compared to uncoated paper. This work offers a sustainable and promising strategy for balancing UV-shielding performance with the functional properties of food packaging paper, opening new avenues for the high-value application of CNCs and SL in the papermaking industry.

The development of efficient and robust bifunctional oxygen electrocatalysts is crucial for advancing rechargeable zinc-air batteries. Although bimetallic composites are promising, conventional doping strategies often lack precise structural control. Herein, we report a sustainable synthesis of Co/Fe heterojunction catalysts from biorefinery lignin, incorporating low-cost Zn as a structural regulator. Zn spacers suppress CoFe alloy crystallization and promote Co 5.47 N formation, while Zn volatilization induces in situ carbon nanotube growth to enhance electronic structure and charge transport. The resulting Zn-CoFe@NLC catalyst exhibited favorable bifunctional performance, with a half-wave potential of 0.84 V for the oxygen reduction reactionand a high kinetic current density (17.2 mA cm -2 at 0.8 V). When implemented in zinc-air batteries, it achieved long cycling stability exceeding 1300 h (at 5 mA cm -2 ) and 1550 h (at 10 mA cm -2 ), more than 2.5 times that of noble metal catalyst (600 h at 10 mA cm -2 ). DFT calculations revealed that the CoFe-Co 5.47 N interface acted as an electron redistribution hub, synergistically enhancing the intrinsic activity of Co/Fe sites. This work underscores the promise of lignin as a sustainable precursor and establishes a generalizable route for rational structural engineering of bimetallic electrocatalysts for energy storage.

In this study, a series of enzymatic hydrolytic lignin (EHL) graft copolymers (EHL- g -P(CA- alt -EPO)s) were successfully synthesized via lignin-initiated ring-opening copolymerization (ROCOP) of cyclic anhydrides (CA) and epoxides (EPO) catalyzed by a metal-free Lewis pair consisting of organic base and triethylborane (TEB). The optimized lignin-initiated ROCOP exhibited widespread monomer adaptability and permitted the synthesis of lignin-based copolymers with tailorable structures and performances via altering anhydrides and epoxides. The chemical structures and thermal properties of EHL- g -P(CA- alt -EPO)s were thoroughly investigated by 1 H, 13 C, HSQC, and 31 P nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FT-IR), matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Furthermore, the EHL- g -P(PA- alt -CHO) exhibited good absorption in the ultraviolet (UV) region with the maximum absorption wavelength of 289 nm and prevented photochromic paint from discoloration via effectively blocking UV light. Benefitting from the conjugated structural moieties in EHL- g -P(PA- alt -CHO), good photothermal effect of E-P1C1 with a photothermal conversion efficiency of 44.93% was achieved under near-infrared (NIR) irradiation, indicating the potential application of EHL- g -P(PA- alt -CHO) in organic UV protective agents and photothermal functional materials .

The selective cleavage of β-O-4 linkages in lignin under mild conditions remains a major challenge for the sustainable production of aromatic chemicals. In this work, CdZnS photocatalysts were synthesized via co-precipitation (CP), hydrothermal (HT), and template-assisted solvothermal ion-exchange (TP) methods and applied to the photocatalytic cleavage of the β-O-4 linkage in 2-phenoxy-1-phenylethanol (PP-ol). Cd 0.5 Zn 0.5 S-CP exhibited outstanding photocatalytic performance under visible-light irradiation, achieving complete conversion of PP-ol with high molar yields of phenol and acetophenone reaching 92.2% and 86.6%, respectively. Comprehensive characterizations revealed that the superior activity of Cd 0.5 Zn 0.5 S-CP originates from the synergistic interplay between its suitably negative conduction band potential (−1.26 eV) and a mesoporous structure with a large accessible surface area. In contrast, Cd 0.5 Zn 0.5 S-HT showed lower activity mainly because of its limited accessible surface area. Cd 0.5 Zn 0.5 S-TP also exhibited inferior performance, which was mainly attributed to its overly positive conduction band potential (−0.60 eV) and insufficient reductive driving force for C–O bond cleavage. Mechanistic investigations demonstrate that the reaction proceeds via a self-hydrogen transfer pathway, with photogenerated electrons playing a dominant role in driving C β –O bond cleavage. This study provides fundamental insights into the rational design of efficient photocatalysts for lignin valorization under mild conditions.
