High-performance epoxy resins (EPs) are indispensable matrices for advanced load-bearing composites, such as wind turbine blades and automotive lightweight structures. Achieving concurrent improvements in the mechanical and thermal performance of EP remains challenging for conventional toughening approaches. In this study, divinylbenzene (DVB)-crosslinked poly(styrene-co-maleic anhydride) (SMA) microspheres were synthesized via self-stabilized precipitation polymerization (2SP) and subsequently incorporated into the EP matrix. The microspheres combine reactive surface anhydride groups with a rigid aromatic backbone. The anhydride groups can participate in the epoxy–anhydride curing reaction, thereby improving the interfacial compatibility between the microspheres and the EP matrix. Meanwhile, the rigid benzene rings restrict segmental mobility and increase the rigidity of the crosslinked network. Curing kinetic analysis revealed that the incorporation of SMA microspheres reduced the apparent activation energy of the SMA/EP system, suggesting that the curing reaction was facilitated. This reduction may be attributed to the participation of surface anhydride groups in the cross-linking reaction and hydroxyl-mediated autocatalytic effects. Mechanical evaluations showed that, at an SMA loading of 2 wt%, the tensile strength of the SMA/EP composite reached 72.0 MPa, corresponding to a 48.8% increase compared with neat EP. At a loading of 3 wt%, the impact strength reached a maximum value of 19.2 kJ/m 2 , indicating a substantial improvement in toughness. In addition, dynamic mechanical analysis (DMA) indicated that SMA microspheres increased the crosslinking density, while differential scanning calorimetry (DSC) showed that the glass transition temperature (T g ) increased by approximately 9 °C compared with neat EP. These results highlight reactive SMA microspheres as promising modifiers for epoxy composites requiring balanced strength, toughness, and thermal performance.

Phillyrin is a critical bioactive constituent of Forsythiae Fructus, exhibiting multiple pharmacological properties, but suffers from poor membrane permeability and low oral bioavailability. In this study, we developed a novel, green method employing whole-cell biocatalysts and natural deep eutectic solvents (NADESs) for the cinnamoylation of phillyrin to improve its liposolubility and bioactivity. Aspergillus oryzae whole cells showed high catalytic activity and stability in co-solvent systems containing hydrophobic NADESs. The NADES-tetrahydrofuran (50%, v/v) mixture maintained a high conversion rate (97.32–99.00%) and excellent 6′-regioselectivity (>99%) under optimal conditions (20 mg·mL−1 whole-cell dosage, 15:1 vinyl cinnamate/phillyrin, at 50 °C). Crucially, Aspergillus oryzae whole-cell biocatalysts exhibited markedly enhanced operational stability across all tested NADES-tetrahydrofuran (50%, v/v) reaction systems, retaining 80.09–97.95% of their original activity after six consecutive batch cycles. This study successfully combined hydrophobic NADESs with a whole-cell biocatalytic system, achieving efficient and regioselective cinnamoylation of phillyrin.

Organic materials have attracted considerable attention in rechargeable aqueous zinc-ion batteries (AZIBs) due to their sustainability and structural tunability. However, the electrochemical performance of existing organic electrodes is severely constrained by limited redox-active sites, high solubility and short conjugated backbones. Herein, a conjugated N-heterocyclic anhydride-based framework, benzoquinone-fused dianhydride (NTBQ), was constructed via solid-state condensation to enable highly reversible Zn 2+ /H + storage. The strategic integration of C=O groups triggers intramolecular electrostatic potential reconstruction and activates adjacent C=N sites, enabling fast and thermodynamically spontaneous multi-electron Zn 2+ /H + co-insertion. The rational structural design endows the NTBQ cathode with a remarkable initial discharge specific capacity of 434.6 mAh g −1 at 0.05 A g −1 and excellent rate capability. Moreover, the extended π-electron delocalization significantly strengthens intermolecular π-π interactions, enhancing the dissolution resistance of NTBQ in aqueous electrolytes and affording long-lasting cycling durability (88.1% retention after 10,000 cycles at 10 A g −1 ). Systematic mechanistic studies demonstrate that the superior electrochemical performance originates from the synergistic redox chemistry of C=O/C=N dual-active centers within the anhydride-based skeleton. These findings demonstrate that intramolecular electronic modulation can effectively evoke multi-electron redox activity, providing an effective avenue for designing high-performance organic cathodes toward advanced AZIBs. Structural optimization from NTPH to NTBQ via incorporation of additional C O groups induces intramolecular electrostatic potential redistribution, enhancing π-electron delocalization and activating adjacent C N sites. This creates synergistic C O/C N dual-redox centers for efficient multi-electron Zn 2+ /H + co-insertion. Download: Download high-res image (130KB) Download: Download full-size image

The precise design of a high-entropy cathode material can achieve excellent performance. Many scholars have conducted extensive research on element design, but studies on the roles of each element are relatively scarce in high-entropy systems. In this project, we adjusted the composition of Cu/Co elements and developed three materials, NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Co0.09Li0.1O2 (HEO-Co), NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Cu0.06Co0.05Li0.1O2 (HEO-CC), and NaNi0.25Fe0.15Mn0.3Ti0.1Ce0.02Cu0.13Li0.11O2 (HEO-Cu). The physical properties and electrochemical performances are analyzed. The appropriate introduction of the Cu element can reduce the voltage difference between the redox potential and the electrochemical polarization. Moreover, it possesses outstanding air and structural stability. The appropriate proportion of the Co element can expand the interlayer spacing of the Na layer, increase the diffusion coefficient of Na+, and achieve excellent rate performance. The appropriate ratio of Cu and Co combines the advantages of both elements, endowing cathode materials with a stable structure, excellent air stability, and electrochemical performance. This work thoroughly explores the specific roles of Cu and Co elements, providing valuable insights for the design of high-entropy cathode materials and a practical pathway toward industrial-scale applications.

Developing high-capacity cathode prelithiation agents remains challenging due to severe kinetic limitations, high operational voltages, or insufficient stability in conventional materials. To address this, we report a cobalt-decorated lithium fluoride composite (S-LiF/Co, with a Co content of 15.76 wt% by ICP-OES) synthesized via a scalable solid-state route. The in situ formed LiF/Co heterointerface serves as a catalytic center, which, as evidenced by theoretical calculations, effectively weakens Li F bonds and significantly lowers the energy barriers for both Li + migration and LiF decomposition. This enables S-LiF/Co to deliver a high initial charge capacity of 886.23 mAh g −1 . When incorporated into NCM811 cathodes, it substantially promotes a stable, LiF-rich cathode electrolyte interphase (CEI). In NCM811||Si/C full cells, this additive effectively compensates for irreversible lithium loss, yielding a high initial energy density of 484.01 Wh kg −1 and superior cycling stability with 80.42% capacity retention after 170 cycles. This work provides an effective interface-engineering strategy to overcome the intrinsic barriers of LiF-based materials, offering a promising prelithiation solution for next-generation high-energy-density batteries.

Although Co modulation can optimize the electronic structure of Pt for hydrogen evolution reaction (HER), PtCo still suffers from chloride ion (Cl–) corrosion in seawater electrolysis, severely limiting its practical applications. This study successfully constructed P-doped PtCo nanoflowers (P-PtCo NFs) with excellent corrosion resistance and rapid water dissociation kinetics through the introduction of P for synergistic electronic regulation. To demonstrate, the P-PtCo NFs require only an 18.2 mV overpotential to achieve 10 mA cm–2 in alkaline seawater, which is significantly lower than those of PtCo NFs (43.2 mV) and commercial Pt/C (65.2 mV), and maintain stable operation for over 500 h in 1 M KOH. X-ray photoelectron spectroscopy and density functional theory analyses reveal strong electron interaction between P atoms and PtCo, which downshifts the d-band center of Pt by 0.038 eV and optimizes the adsorption strength of active sites toward hydrogen intermediates. In situ Raman spectroscopy and CO stripping experiments further illustrate that P doping reconstructs the electronic distribution of Pt, effectively promoting water molecule dissociation. This work highlights the essential role of P in conferring both corrosion resistance and fast reaction kinetics, providing a design strategy for efficient and durable seawater electrolysis catalysts through multicomponent electronic synergism.

The electrochemical CO 2 reduction reaction (CO 2 RR) to CO faces challenges from slow kinetics and complex pathways, necessitating active, selective, and stable catalysts. This study presents a direct coordination strategy that enables the in situ growth of cobalt tetranitrophthalocyanine (CoTNPc) on Co-embedded N-rich carbon matrix (Co/NC), forming a CoTNPc/NC composite. The directly axial coordination regulates the electronic configuration of Co-N sites, accelerating the *CO formation and desorption. The CoTNPc/NC electrocatalyst achieves a peak CO Faradaic efficiency for (FE CO ) of 96.7% at −0.9 V vs. RHE in H-cell. Furthermore, in the Flow-cell, it maintains FE CO > 90% over a wide potential range (−0.4 V to −0.9 V vs. RHE) and demonstrates durability exceeding 15 h in stability testing. In situ attenuated total reflection infrared (ATR-IR) spectroscopy and Density functional theory (DFT) calculations elucidate that the remarkable performance is driven by the improved electrical conductivity and weakened interaction between the *COOH intermediate and Co sites. This work offers a novel approach to optimizing catalyst-support interactions for electrocatalyst design.

Atherosclerosis (AS) is characterized by chronic, persistent inflammation and lipid deposition. Macrophage mitochondrial dysfunction leads to excessive release of reactive oxygen species (ROS), exacerbating inflammatory responses and lipid metabolism dysfunction. This study developed a novel nanodrug system (TM@AG NPs) for restoring macrophage mitochondrial function. The system is based on the co-assembly of astaxanthin (AST) and geniposide (Gen), with macrophage membrane coating and triphenylphosphonium (TPP) modification. In vitro experiments demonstrated that mitochondria-targeted TM@AG NPs promoted the repolarization of macrophages from the M1 to the M2 phenotype and suppressed inflammation by efficiently scavenging mitochondrial ROS (mtROS), restoring mitochondrial respiration and energy supply, thereby ameliorating lipid metabolism disorders. In vivo assay using ApoE −/− mice model demonstrated that TM@AG NPs efficiently accumulated in atherosclerotic plaques, significantly reduced plaque area, cleared the necrotic core, and enhanced plaque stability. In summary, this study presents a sequentially targeted strategy for the precise treatment of AS.

Electrocatalytic selective hydrogenation represents a green and atom-efficient synthetic route, yet it remains fundamentally challenging to simultaneously achieve high activity and exceptional selectivity while suppressing competing side reactions, primarily hydrogen evolution and over-hydrogenation. To address this, we fabricate atomically Pd 1 Cu 1 alloy nanoparticles on carbon cloth (Pd 1 Cu 1 /CC) via a facile co-electrodeposition method. The catalyst enables highly efficient and selective electrocatalytic hydrogenation of 2-methyl-3-butyn-2-ol (MBY) to 2-methyl-3-buten-2-ol (MBE) in an aqueous alkaline electrolyte, delivering an MBE production rate of 0.88 mol h −1 g Cat. −1 with 96% selectivity and 92% Faradaic efficiency—performance superior to its monometallic counterparts. The catalyst also demonstrates excellent stability, broad substrate applicability, and promising potential for industrial application. Combined experimental and theoretical results reveal that the Pd 1 Cu 1 /CC catalyst exhibits a lowered activation energy (40.89 kJ mol −1 ), which not only facilitates active *H generation via water dissociation but also weakens the adsorption of MBE due to Cu-induced electronic modulation. This dual mechanism ensures efficient *H supply and prompts product desorption, thereby synergistically boosting selectivity while suppressing both over-hydrogenation and the hydrogen evolution reaction. This work provides insights into the design of advanced electrocatalysts for selective hydrogenation from the perspective of alloy catalyst, contributing to sustainable organic synthesis strategies.

Ceramic membrane separation technology has great potential for the treatment of oily wastewater. However, factors such as low filtration flux, high production costs, and a complicated preparation process hinder its large-scale application. In this study, an asymmetric-structure ceramic microfiltration membrane was successfully prepared using dry-pressing and high temperature co-firing method using alumina whiskers as the membrane layer. The maximum pore size of the ceramic membrane prepared by co-fired at 1450 °C was 0.659 μm, and the pure water flux was 1795L/(m2 ⋅ h ⋅ bar). When treating a 1000 mg/L oil/water emulsion, the ceramic membrane maintained separation flux of 251L/(m2 ⋅ h ⋅ bar) after ten filtration cycles, and the oil rejection efficiency consistently remains above 99%. Moreover, the one-step high-temperature co-firing process will further improve the overall physical and chemical properties of ceramic membranes, providing important reference for improving the application efficiency of ceramic membranes in complex working conditions.

Abstract Global warming has spurred interest in CO2 utilization. Coupling reverse water–gas shift (RWGS) with hydroformylation allows olefins to react with H2/CO2 to produce valuable aldehydes, which is a profitable reaction and helps with carbon fixation. However, temperature mismatch between the two reactions and limited mechanistic understanding hinder the rational design of catalysts. Using density functional theory (DFT) calculations and experimental evaluations, we investigated the effects of different phosphine ligands and acid additives on the performance of silane-free CO2 hydroformylation. Formic acid alters the CO2 activation pathway and reduces the energy barrier, thereby improving catalytic activity and chemoselectivity. The effects of reaction conditions reveal a competitive relationship between CO2 reduction and olefin carbonylation, suggesting that balancing RWGS and hydroformylation rates enhances catalytic performance. Our work not only deepens the mechanism understanding of silane-free CO2 hydroformylation but also paves the way for the rational design of subsequent high-performance catalysts.

Metal Fe and nonmetal S were co-doped in NiP to modulate the electronic structure of NiP. • Metal Fe doping can improve the electroconductive of the NiP, improving the electron transfer ability and reaction kinetics of HER. • Nonmetal S doping can modulate the band structure for the high electronegativity of S element. • The synthesized Fe, S-NiP exhibited an overpotential of 35 mV at the current density of 10 mA/cm 2 . Nickel phosphide (NiP) is an effective non-noble metal electrocatalyst for the hydrogen evolution reaction (HER). However, the application of NiP is limited for the poor hydrogen adsorption and slow charge transfer during HER process. Herein, metal Fe and nonmetal S were co-doped into NiP to overcome an aforementioned drawbacks of NiP. Metal Fe doping can improve the electroconductive of the NiP, improving the electron transfer ability and reaction kinetics of HER. Nonmetal S doping can modulate the band structure for the high electronegativity of S element. The optimized d-band centers of Ni site benefited the HER reaction and improved the catalytic performance of Fe, S-NiP. The synergistic effect of metal and nonmetal doping further enhanced the catalytic activity by optimizing proton adsorption and hydrogen desorption. This work provided a guidance for metal and nonmetal co-doping for transition metal-based materials’ catalytic performance improvement.
