To improve the compatibility and reactivity of lignosulfonate (LS) with epoxy oligomers, the LS was firstly functionalized with anhydride via the carboxylation reaction . The carboxylated lignosulfonate (CLS) reinforced epoxy resin with excellent mechanical and shape memory performance was prepared facilely via distributing the CLS into the combined epoxy monomers of DGEBA and PEGDGE with the aid of water, rather than using the normal organic solvents . The incorporated CLS promoted the curing reaction of epoxy resin. A typical sea-island structure was formed in the cured sample at the CLS content of 5 phr, exhibiting the highest increases in tensile strength , modulus, elongation at break and toughness by 23.8 %, 18.2 %, 217 % and 113 %, respectively, relative to neat epoxy. Interestingly, the incorporation of CLS at a proper amount led to the simultaneous strengthening and toughing effects on cured epoxy resin, which could be attributed to the rigid structure of CLS covalently introduced in the epoxy resin network and the heterogeneous structure formed in the epoxy matrix. The rigid CLS component also restrained the movement of chain segments, consequently, the mechanical stability was enhanced and the fast shape recovery rate of epoxy resin network was slowed down to some extent.

Hydrate-based technology is an innovative and efficient way to store and transport methane (CH4), offering advantages such as high efficiency, low energy cost, and safe utilization. This study focuses on the effects of two promoters, i.e., 1,3-dioxolane (1,3-DIOX) with low toxicity and the biodegradable sodium lignosulfonate (SL-Na), on the formation of CH4 hydrates. The results indicate that at 3.0 MPa, the system of 5 mol % 1,3-DIOX + 0.5 wt % SL-Na leads to the maximum increase in nucleation temperature. Besides, 1,3-DIOX significantly increases the nucleation temperature, while high concentrations of SL-Na decrease it. Additionally, 1,3-DIOX can accelerate the formation of CH4 hydrates, while the SL-Na systems require longer growth times and exhibit higher gas consumption. In the study of the compound system, the 5 mol % 1,3-DIOX+0.25 wt % SL-Na compound system has the highest nucleation temperature of 283.65K, the shortest induction time of 1.1 min, and the highest gas consumption rate, which is about 27.82 times that of the pure water system. The 1 mol % 1,3-DIOX+0.5 wt % SL-Na compound system has the longest growth time of 652.6 min and the highest gas storage capacity, which is about 7.41 times that of the pure water system. Although the 1,3-DIOX + SL-Na compound systems generally take longer to nucleate, they accelerate the gas consumption rates overall. In conclusion, combining 1,3-DIOX and SL-Na can improve the kinetic formation of CH4 hydrate, providing valuable methods for optimizing CH4 storage efficiency.

Lignosulfonate (LS) had various influences on the enzymatic digestibility of lignocelluloses for the complicated structure of LS. The effect of the complex of LS and cationic surfactant cetyltrimethylammonium bromide (LS–CTAB) on the enzymatic digestibility of corn stover and Avicel was investigated in this study. The LS–CTAB catanionic surfactant could significantly improve the enzymatic digestibility of Avicel and corn stover from 42.1 and 24.3% to 62.3 and 56.2%, respectively. In addition, the effect of LS–CTAB with various molecular weights and sulfonation degrees of LS and varied alkyl chain lengths of CnTAB on the enzymatic digestibility of Avicel was further investigated to reveal that the mechanism of LS–CTAB enhanced the enzymatic digestibility of cellulose. LS adsorbed on cellulase aggregates and dispersed the aggregates to form the smaller and more hydrophilic LS–cellulase aggregates. CTAB neutralized the electronegative charge of LS–cellulase aggregates, improved the interaction between cellulase and cellulose, and enhanced the enzymatic digestibility of cellulose.

The sodium lignosulfonate (SL) modified Fe 3 O 4 (Fe 3 O 4 -SL) nanoparticles with excellent peroxidase-like activity were prepared by one-step solvothermal method, which were applied to sensing hydrogen peroxide (H 2 O 2 ) and glutathione (GSH) with color change. Firstly, the morphology and composition of Fe 3 O 4 -SL nanoparticles were characterized. The results showed that the synthesized Fe 3 O 4 -SL nanoparticles had a spherical structure with an average diameter of 220 nm. Subsequently, the peroxidase-like activity of Fe 3 O 4 -SL nanoparticles was investigated by catalyzing the formation of blue-colored oxidized TMB (ox-TMB) by 3,3’,5,5’-tetramethylbenzidine (TMB) in the presence of H 2 O 2 . Mechanism studies showed that the Fe 3 O 4 -SL nanoparticles exhibited better catalytic activity than natural horseradish peroxidase (HRP), and the catalytic pathway abode by the ping-pong mechanism. Finally, the colorimetric sensor for H 2 O 2 was established, which had a linear range of 0.5–150 μmol/L, a detection limit of 0.139 μmol/L and good selectivity. In addition, according to the decolorization reaction of ox-TMB and GSH and the scavenging effect of GSH on hydroxyl radicals, a colorimetric GSH sensor was further constructed. Based on the above results, a colorimetric detection platform for GSH was built, by which a detection range of 0.5–25 μmol/L and a detection limit of 0.08 μmol/L were obtained. The results above showed that the colorimetric sensing system constructed here had a wide detection range, good selectivity and stability for detection of GSH, which would provide an important reference in food monitoring, biomolecule detection and other fields.

It is a challenge to interpret the signals obtained by Quartz Crystal Microbalance (QCM) and Surface Plasmon Resonance (SPR) accompanied with in the significant changes of the density and/or refractivity of media. The work presented herein focuses on demonstrating a universal in-situ and real-time monitoring methodology for ultrathin film formation on gold chips in varied media. Biomimetic model cellulase/enzyme film was immobilized in-situ on gold surface of sensors, followed by revealing its interaction with lignosulphonate in the media changed from ethanol-based to aqueous ones. Combining the techniques of Quartz Crystal Microbalance with Dissipation monitoring (QCM-D) and Multi-parametric Surface Plasmon Resonance (MP-SPR) along with respective software and models enabled us to precisely characterize the thickness, viscous and shear elastic moduli, and the coupled solvent for individual layer formed over the entire process, which are unachievable with conventional methods. The methodology provides real-time monitoring of filming process and offers us an in-situ qualify control approach to the biomimetic model films formed on different substrates including gold chip.

In recent years, developments of drug delivery systems of antibiotics have been needed for improving antibacterial performance due to massive usage of antibiotics. With the global growing concept of being green, lignosulfonate (LS) has been deemed as an ecofriendly stabilizer and carrier that holds promise in preparing nanocomposites for antibacterial treatment. At the same time, LS and gentamicin sulfate (GS) have been proven to form a nanocomposite (LS-GS) with highly uniform size and roundness in solution. It also possesses a good loading capacity of GS. Density functional theory (DFT) verified that the interaction forces in LS-GS, a nanocomposite with self-assembly characteristics, were mainly combined via hydrogen bonds, van der Waals forces, and repulsion. The obtained LS-GS has the biocompatible, biodegradable, and low-cost merits of LS. It also exhibited excellent in vitro antibacterial activities against Escherichia coli and Staphylococcus aureus due to the antibacterial properties of GS. Moreover, an in-depth antibacterial study revealed the highly efficient antibacterial and wound-healing applications of LS-GS in vivo. Collectively, LS, a carrier material with low cost, which strikingly increases the antibacterial and wound-healing ability of GS in vitro and in vivo, will contribute to the production of large-scale antibacterial nanocomposites.

Carbon/transition metal oxide composites exhibit promising potential as electrode materials for energy storage, but regulating their interfacial composite structures remains a formidable challenge. In this work, we develop a lignosulfonate-assisted synthesis strategy to fabricate a porous carbon-supported MnO2 composite (LSC/MnO2-2) with a robust interface for asymmetric supercapacitors (ASCs). The functionalized lignin porous carbon, achieved through π–π interactions with lignosulfonate, exhibited improved dispersibility, thereby facilitating the deposition of MnO2 onto the carbon matrix. Consequently, LSC/MnO2-2 demonstrates uniform MnO2 loading and enhanced interfacial bonding. The robust interaction between Mn sites and the lignosulfonate-functionalized carbon substrate can promote electron transfer and ion transfer kinetics, effectively activating the electrochemical activity of MnO2. The as-prepared LSC/MnO2-2 demonstrates high specific capacitances of 750 F/g at 0.5 A/g and 400 F/g at 10.0 A/g in a 1 M KOH electrolyte. Furthermore, the assembled ASC exhibits an outstanding energy density of 54.4 Wh/kg at 998.2 W/kg and excellent cyclic stability (94.7% retention over 10,000 cycles at 2.0 A/g). This study presents an alternative method to precisely control the deposition of metal oxides onto carbon materials, aiming to enhance the performance of carbon composites.

Layer-by-layer (LbL) assembly technology is a facile method for constructing thin film composite membrane. Herein, a novel nanofiltration (NF) membrane was prepared by LbL assembly of polyethyleneimine (PEI) and sodium lignosulfonate (LS) followed by cross-linking. The surface composition, morphology, and property of PEI/LS bilayer were detailedly investigated by FTIR/ATR, XPS, SEM, AFM, and water contact angle test. The PEI/LS bilayer full of amino and hydroxyl groups presents increased roughness and improved hydrophilicity. Moreover, the NF performance of PEI/LS LbL assembly membranes can be modulated by bilayer number, polyelectrolyte concentration, and salt content. The water flux reduced while the salt rejection greatly improved as increasing the bilayer numbers, PEI concentration, or NaCI content. More than 95% MgSO 4 and MgCI 2 , as well as 80% NaCI can be rejected by a NF membrane prepared by 6 PEI/LS bilayers, 1 wt% PEI, 0.5 wt% LS, and 1 mol/L NaCI. Furthermore, this NF membrane can be used to remove more than 95% heavy metal ions (Cd 2+ , Zn 2+ , Mn 2+ , Cr 2+ , Cu 2+ , and Ni 2+ ). This work proposed a promising NF membrane by using PEI/LS as low cost polyelectrolytes and facile LbL assembly method, which should receive much attention in water purification.

The alarming overuse of antibiotics poses a serious threat to the environmental security. Herein, a hybrid aerogel adsorbent, sodium lignosulfonate functionalized polyethyleneimine/carboxymethyl chitosan@ZIF-8 (CCSL@ZIF-8), was fabricated by introducing sodium lignosulfonate into polyethyleneimine/carboxymethyl chitosan (CSSL) and then in situ uniformly anchoring of ZIF-8 on CSSL aerogel. The incorporation of sodium lignosulfonate not only enhanced the mechanical properties of CCSL , but also provided a large number of chelating sites for Zn 2+ and promoted the formation of ZIF-8. The sorption behavior and mechanism were studied by batch adsorption experiments and characterization analysis. The experimental results demonstrated that the maximum adsorption capacity of CCSL-1.0@ZIF-8 was 231.36 mg/g with a tetracycline (TC) concentration of 200 mg/L at 303 K, which was 7 times higher than that of CCSL-1.0 (30.73 mg/g). The absorption process followed the pseudo-second-order kinetic model and Freundlich isothermal model, and the process of adsorbing TC was dominated by multilayer chemisorption. The adsorption mechanism included pore filling, coordination bonds, hydrogen bonding, electrostatic interactions and π-π interactions. Moreover, the removal efficiency of TC by CCSL-1.0@ZIF-8 was maintained above 78 % after 6 cycles. Overall, this work presents a potential bio-based adsorbent for the effective removal of tetracycline from wastewater and provides a novel, facile, and green chemical technique for high-value utilization of lignin. Furthermore, the prepared biomass-based hybrid adsorbent has outstanding reusability and water stability, which has broad practical application prospects in antibiotic wastewater treatment.

A semi-immobilized CL coating is designed for stable Zn anodes. • Hydrophobic framework isolates water and repels SO 4 2− via sulfonate. • Ca 2+ tip-shielding and lignosulfonate anions guide uniform Zn deposition. • Symmetric cell cycles 4500 h; full cell retains 93.99% after 1500 cycles. Aqueous zinc-ion batteries (AZIBs) are attractive candidates for large-scale energy storage, yet the zinc anode is plagued by parasitic reactions and dendrite growth. Herein, we propose a semi-immobilized ion-regulation concept by engineering a hydrophobic composite coating on zinc foil (denoted as CL@Zn coating) to form the CL@Zn electrode. The coating consists of calcium lignosulfonate (CL), conductive carbon black, and PVDF. Unlike conventional fully solid coatings or fully dissolved additives, this design enables a small fraction of CL to controllably dissolve, releasing functional lignosulfonate anions and Ca 2+ ions, while the majority remains anchored within the three-dimensional (3D) framework. This creates a dynamic, synergistic protection system: the coating physically repels water and SO 4 2− ; the dissolved anions regulate Zn 2+ transport and favor (101)-oriented Zn growth, while released Ca 2+ ions contribute to a “tip-shielding effect” against dendrites. Moreover, a compact yet microporous Zn 4 SO 4 (OH) 6 ·xH 2 O (ZHS)-derived interfacial layer forms in situ at the coating/electrolyte interface, acting as a beneficial SEI-like interphase that facilitates interfacial ion transport and further stabilizes Zn deposition. Consequently, the CL@Zn symmetric cell cycles for nearly 4500 h at 0.5 mA cm −2 , and the CL@Zn//MnO 2 /CNT full cell exhibits a capacity retention of 93.99% after 1500 cycles at 1 A g −1 . This work presents a versatile, biomass-derived dynamic interface strategy for durable metal anodes. A semi-immobilized calcium lignosulfonate coating creates a hydrophobic, ion-regulating interface that suppresses dendrites and side reactions, enabling ultra-stable zinc anodes for aqueous zinc-ion batteries.

Biomass-derived porous carbon holds great promise as an electrode material for supercapacitors due to its low cost and sustainability. However, single-activator strategies typically fail to achieve microporous-mesoporous structure with high specific surface area (SSA) and micropore volume of such carbon materials, thereby limiting their capacitive performance. Therefore, inspired by the pyrolysis behavior of sodium lignosulfonate, we innovatively propose a novel activation system for preparing N/O/S co-doped biomass microporous-mesoporous carbon (SLCA): utilizing chitosan carbon and sodium lignosulfonate as self-doping carbon sources, potassium hydroxide as the primary activator, and sodium lignosulfonate as the self-templating activator. The microporous volume is a key factor influencing specific capacitance. Specifically, the SLCA-700 (activated at 700 °C) has a microporous-mesoporous structure with abundant N/O/S heteroatoms doping and a SSA of 2378.7 m 2 ·g −1 , and achieves a high micropore volume of 0.84 cm 3 ·g −1 , which is 0.24 cm 3 ·g −1 higher than that of the KOH activation system alone. Furthermore, the SLCA-700 electrode exhibits an outstanding specific capacitance of 305.9 F·g −1 at 0.5 A·g −1 , and supercapacitor shows excellent cycling stability (97.0% capacitance retention after 10,000 cycles). This study proposes a dual activation mechanism for preparing microporous-mesoporous carbon with a high SSA, providing a viable strategy for producing high-performance supercapacitor electrode materials.

Li/La bimetallic catalyst supported on hierarchical porous carbon was prepared. • RSM-BBD optimization yielded 99.5% oil conversion at 60.14°C in 2.47 h. • High TOF, low E-factor and PMI meet green chemistry principles. Sodium lignosulfonate, a major byproduct of the sulfite pulping industry, can be converted into carbonaceous materials for catalyst preparation, enabling high‑value utilization of industrial waste. In this study, a hierarchical porous carbon support (HPC) was prepared from sodium lignosulfonate and sodium humate through a two‑step process of carbonization and KOH activation. Subsequently, a series of heterogeneous base catalysts, were synthesized by loading bimetallic active components (Li and La) onto HPC via an ultrasonic‑assisted impregnation method. Optimization of the reaction parameters was conducted utilizing response surface methodology in conjunction with the Box-Behnken experimental design (RSM-BBD). The optimum reaction conditions were identified as catalyst amount of 6.96 wt%, methanol/oil molar ratio of 28.52:1, temperature of 60.14°C, and reaction duration of 2.47 h, under which an oil conversion rate of 99.5% was achieved. Kinetic analysis indicated that the transesterification process conformed to pseudo-first-order kinetic behavior, with an apparent activation energy determined to be 48.06 kJ·mol −1 . Thermodynamic parameters (ΔH = 45.42 kJ·mol −1 , ΔS = -142.19 J·mol −1 ·K −1 ) confirmed that the reaction is endothermic and nonspontaneous. The catalyst maintained a soybean oil conversion of 79.5% after five consecutive cycles, with an estimated production cost of approximately $4.74 per kilogram. Additionally, the catalyst demonstrated a high turnover frequency (TOF) value of 30.06 h −1 along with low E‑factor (0.105) and process mass intensity (PMI) (1.105) values, consistent with green chemistry principles.
