Acrylic shape memory polymers rely on the rate of thermal-induced shape recovery as a key index that directly influences their effectiveness in applications that demand controllable deformation. Herein, varying concentrations of sodium lignosulfonate are added to a solution of methyl methacrylate (MMA) and polyethylene glycol diacrylate (PEGDA) during polymerization to modify the polymer network structure of MMA/PEGDA, thereby improving its thermotropic response. The results showed that incorporating 12 wt% lignosulfonate improved the shape recovery rate of SMP from 50% to 100%, while maintaining a tensile strength of 6.9 MPa. The LSMP’s storage module exceeds that of the SMP by over twofold at room temperature, and its energy release rate increases more rapidly with increasing temperature. The chemical bonding of lignosulfonate to PEGDA/MMA segments was found to improve its thermotropic response efficiency by adjusting the polymer network, as evidenced by multiple characterizations. This study highlights the potential to enhance the thermotropic response of acrylic SMP by adding lignosulfonate, while also offering new perspectives on lignosulfonate waste management.

Developing highly active, durable, and cost-effective oxygen reduction reaction (ORR) catalysts is crucial for fuel cell commercialization through the use of non-precious metal alternatives to platinum. In this study, the tunable dodecahedral Fe-N-C catalysts were synthesized through controlled pyrolysis of Fe-doped zeolite imidazolate framework-8 (ZIF-8) precursors. The optimized 5% Fe@NC-8 catalyst demonstrates excellent ORR performance with an onset potential of 0.92 V vs. RHE, a half-wave potential (E 1/2 ) of 0.83 V vs. RHE, and a limiting diffusion current density (j d ) of 6.06 mA cm −2 , surpassing commercial 20% Pt/C catalysts (onset potential 0.89 V vs. RHE; E 1/2 0.81 V vs. RHE; j d 4.27 mA cm −2 ). It also shows strong durability, retaining 86.16% of its current after prolonged polarization (@0.80 V vs. RHE for 10,000 s) and minimal negative shift in half-wave potential after extensive cycling(@200 mV s −1 for 5000 CV cycles). The enhanced catalytic performance is attributed to (i) possessing a high specific surface area (319 m 2 g −1 ) and favorable porosity to maximize active site accessibility; (ii) having abundant active sites of Fe-N x , graphitic N, and pyridinic N as active catalytic centers; and (iii) forming N-doped carbon matrices to provide a conductive framework. These advantages boost the density of accessible active sites and thus remarkably improve the ORR catalytic activity.

Rational microstructure design and compositional regulation have emerged as effective pathways to enhance electromagnetic wave (EMW) absorption, However, simultaneously achieving strong absorption, broad bandwidth, thin thickness and low filler loading remains challenging. Herein, three-dimensional hierarchical heterostructures comprising amorphous carbon-wrapped magnetite supported on flower-like reduced graphene oxide (Fe₃O₄@C/FRGO) was constructed through spray-drying assembly, spatially confined solvothermal crystallization, and defect-modulated carbonization. By tailoring the reduction degree of FRGO and tuning ferrite composition through thermal treatment, the dielectric-magnetic properties and interfacial interactions are precisely regulated. With merely ≈ 3.26 wt% incorporation of FRGO, the optimized composite exhibits a minimum reflection loss (RL min ) of -66.29 dB at 1.94 mm (20 wt% filler) and a broad effective absorption bandwidth (EAB) of 6.60 GHz (11.30–17.90 GHz) at 2.73 mm (30 wt% filler). This exceptional performance is attributed to the engineered heterointerfaces that facilitate multi-path energy dissipation via magneto–dielectric coupling optimized impedance matching, intensive interfacial polarization from abundant hierarchical architectures and the flower-like structure induced multiple scatterings. This study highlights the pivotal role of interfacial engineering in heterostructured absorbers and offers a design paradigm for high-performance EMW-absorbing materials through coordinated component–structure modulation.

Hole-transport-layer (HTL)-free carbon electrode perovskite solar cells (C-PSCs) are promising candidates for low-cost photovoltaic applications, but their performance is still limited by defect-induced recombination and insufficient long-term stability. Herein, ethacridine lactate (EAL) is employed as a multifunctional additive in the perovskite precursor solution to regulate film quality and interfacial properties. Owing to the presence of a carboxyl group in the lactate anion and two amino groups in the ethacridine cation, EAL interacts with undercoordinated Pb 2+ and dangling I − species, which stabilizes the perovskite structure and promotes charge transport across the perovskite/carbon interface. Consequently, the EAL-modified films show improved morphology and reduced defect density, resulting in enhanced photovoltaic performance. The optimized device delivers a power conversion efficiency of 16.54% and retains 80% of its initial efficiency after 1200 h without encapsulation. This work highlights an effective additive-engineering strategy for achieving efficient and stable HTL-free carbon electrode PSCs.

In this work, Er x Eu 1−x MnO 3−δ (x = 0, 0.2, 0.5, 0.8, 1.0) ceramics were synthesized via conventional solid-state reaction, and the synergistic effects of phase coexistence and defect chemistry on dielectric properties were investigated. Multiple experimental validations confirm composition-dependent structural evolution from orthorhombic to hexagonal phases, with stable two-phase coexistence occurring at x = 0.5. X-ray photoelectron spectroscopy reveals that this optimal composition possesses the maximum Mn 2+ fraction (35.19%) and oxygen vacancy concentration. The x = 0.5 sample exhibits an ultrahigh dielectric permittivity (ε′ ≈ 3.5 × 10 4 at 1 kHz, 300 K) and a low loss tangent (tanδ ≈ 0.03). Impedance spectroscopy and conductivity analysis verify that phase boundaries and associated defect clusters promote interfacial polarization while impeding long-range charge migration. This study demonstrates that the synergy of controlled two-phase coexistence and defect engineering is a valid strategy for achieving high-performance rare-earth manganite dielectrics.

Lupus nephritis (LN) is a common renal complication of systemic lupus erythematosus, and its severity is closely correlated with disease prognosis. Conventional therapy for LN faces challenges including multiple side-effects caused by systemic administration and low drug delivery efficiency due to lack of organ targeting. Herein, we designed a renal-targeted delivery platform based on C-C Motif Chemokine Receptor 2 (CCR2)-C-C Motif Chemokine ligand 2 chemotaxis, constructed by engineering CCR2-overexpressing mesenchymal stromal cell-derived EVs loaded with mycophenolic acid (MPA)-encapsulated MSNs (MPA@CMSNs). In LN models, MPA@CMSNs enabled efficient delivery of MPA into renal region and significantly alleviated kidney inflammation. Mechanistically, MPA@CMSNs effectively inhibited the proliferation and differentiation of proinflammatory immune cells, while concurrently suppressing the Dectin3/NF-κB signaling pathway in macrophages to remodel and optimize the renal immune microenvironment. Collectively, our findings present an efficient renal-targeted strategy with profound therapeutic efficacy against LN, offering a promising approach for targeted disease treatment.

Facing the global shortage of forest resources, oriented strand board (OSB) has attracted increasing attention for its efficient use of small-diameter timber and wood-processing residues. However, its inherent flammability and the deterioration of mechanical properties induced by conventional flame retardants remain critical challenges. In this study, a low-dosage borax (BX)-melamine cyanurate (MCA)-nano-alumina (Al 2 O 3 ) synergistic compatibilization strategy was proposed to simultaneously enhance the fire safety and mechanical performance of OSB. The designed system forms a robust “ceramic–carbon composite expanded protective layer” during combustion, effectively suppressing heat transfer and thermal decomposition. Compared with neat OSB, the residual char yield increased by 78%, while the peak heat release rate, total heat release, total smoke production, and peak smoke production were reduced by 15%, 32%, 69%, and 89%, respectively. Meanwhile, BX-mediated interfacial bonding enabled strong chemical interactions among flame retardants, Wood shavings (WS), and 4,4′-methylenediphenyl diisocyanate (MDI), improving interfacial compatibility. As a result, both longitudinal and transverse bending strength and modulus of OSB were well maintained at high levels. This work provides a novel and practical route for developing high-performance flame-retardant OSB, which not only enables the high-value utilization of wood but also significantly advances the engineering applications of OSB in advanced technology fields.

Within the framework of the global dual-carbon strategy, this study presents a sustainable process for the one-step synthesis of 1,4-cyclohexanedimethanol-based polycarbonate (PCMC) utilizing raw materials sourced from spent lithium battery electrolytes. The study examines the impact of incorporating 1,3-propanediol (PDO) into poly(1,4-cyclohexanedimethylene carbonate) (PCMC). Fourier Transform Infrared Spectroscopy (FTIR) confirmed the successful incorporation of PDO, evidenced by the presence of hydroxyl (-OH) groups and shifts in carbonyl (C = O) and ether (C-O-C) vibrations. Differential Scanning Calorimetry (DSC) indicated a reduction in glass transition temperature ( T g ) and a decrease in crystallinity with increasing PDO content, as evidenced by broader and lower melting peaks. Thermogravimetric Analysis (TGA) showed improved thermal stability, characterized by a delayed onset of decomposition and higher char residue at elevated PDO levels. The reduction in complex viscosity and enhancement in chain flexibility facilitate processing but may affect melt strength. Dynamic mechanical analysis revealed enhanced viscoelastic behavior and energy dissipation in PDO-modified PCMC samples. Collectively, the addition of PDO improves the flexibility, thermal stability, and processability of PCMC, rendering it suitable for applications that necessitate deformability and ease of fabrication.

Two phosphorus-containing polymethacrylate viscosity index (VI) improvers were designed and synthesised successfully via free radical polymerisation. Specifically, the two polymers were prepared by copolymerising dodecyl methacrylate with two different phosphorus-containing monomers, namely 2-hydroxyethyl methacrylate phosphate and bis[2-(methacryloyloxy)ethyl] phosphate, respectively. It is noteworthy that the synthesized polymers demonstrate remarkable VI-improving performance. When incorporated at a concentration of 5 wt% into the mineral base oil (150 N, base oil grade), all polymer samples effectively enhance the viscosity index. As multifunctional additives, they also demonstrate superior tribological performance in comparison to the commercially available 6300 V—their shear stability is superior, indicating excellent shear resistance. In situations involving extreme pressure performance, the two polymers (P(LMA-MP) and P(LMA-DP)) have been shown to significantly increase the load-carrying capacity of the 150 N mineral base oil from 200 N to a maximum of 600 N. They have also been demonstrated to exhibit remarkable advantages in terms of anti-wear and friction-reduction properties, effectively lowering the friction coefficient and wear volume. The structural modification of the copolymers (introduction of phosphorus-containing groups) is responsible for the enhanced tribological performance: Energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS) analyses of the friction surfaces reveal that a protective friction film, mainly composed of iron oxide and iron phosphate, is formed, while the polymethacrylate backbone ensures their excellent VI-improving capability.

Tetrabromobisphenol A (TBBPA), as the most widely used brominated flame retardant, was characterized by its recalcitrance to degradation and bioaccumulation. To address this limitation, a carbon layer-protected Cu 2 O (C-Cu 2 O/Cu) cathode was fabricated via in-situ chemical oxidation and calcination followed by glucose impregnation-carbonization, which was subsequently coupled with silver-loaded TiO 2 (Ag-TiO 2 /Ti) anode prepared by anodic oxidation and photodeposition to construct an efficient photoelectrocatalytic (PEC) system. By optimizing preparation parameters such as impregnation concentration and calcination temperature, the photocurrent density of the C-Cu 2 O/Cu cathode was enhanced to 2.6 times higher than that of Cu 2 O/Cu, and it maintained stable performance during 1200 s of light on/off cycles, contrasting with the rapid decay of Cu 2 O/Cu. Within the PEC system, the C-Cu 2 O/Cu photocathode achieved a TBBPA degradation efficiency of 97.1%, significantly surpassing the 87.2% of Cu 2 O/Cu. Systematic investigation of various applied voltages, pH levels, and electrolyte concentrations revealed that the optimal operating parameters were a 1.5 V bias, pH 9.5 and 0.05 mol/L Na 2 SO 4 . Radical trapping experiments confirmed that hydroxyl radicals (·OH) and superoxide radicals (·O 2 − ) served as the primary reactive species, while GC–MS analysis elucidated the degradation pathway involving debromination, ring cleavage, and mineralization. This study provided a novel strategy for enhancing the stability of Cu 2 O photoelectrodes and achieving efficient degradation of persistent organic pollutants with the PEC system .

Semiconductor photocatalysis offers an environmentally sustainable approach for the elimination of organic contaminants from wastewater. However, the photocatalytic performance of Zn 2 In 2 S 5 (ZIS) is often limited by nanosheet aggregation, insufficient exposure of active sites, and the incomplete understanding of reactive oxygen species (ROS) evolution. In this study, marigold-like ZIS microspheres with a 2D-3D hierarchical porous structure were fabricated, and their performance in the photocatalytic degradation of rhodamine B (RhB) was investigated. The structural and physicochemical properties of the obtained ZIS were systematically investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–Vis diffuse reflectance spectroscopy (DRS), and Mott–Schottky analysis. The results demonstrated that this unique structure integrates the advantages of the short charge migration distance of 2D materials and multiple light scattering/adsorption sites of 3D structures. Under AM 1.5 simulated sunlight irradiation, the as-prepared ZIS photocatalyst exhibited excellent photocatalytic activity, with a RhB degradation efficiency of up to 99.7% within 60 min and an apparent reaction rate constant (k) of 0.09 min⁻ 1 , which compares favorably with most previously reported ZIS-based photocatalysts. Through trapping experiments, electron spin resonance (ESR) spectroscopy and qualitative detection of hydrogen peroxide (H 2 O 2 ), the photocatalytic reaction mechanism of ZIS was elucidated: superoxide radical (·O 2 − ) is the primary active species, followed by photogenerated hole (h⁺), whereas hydroxyl radical (·OH) make the least contribution. More importantly, a cascade mechanism of “ O 2 − – H 2 O 2 –·OH” was proposed in this work, which not only resolves the inherent contradiction of insufficient valence band position of ZIS but also demonstrates the potential of hierarchical zinc indium sulfide photocatalysts for efficient environmental remediation applications.

The increasing demand for high-energy-density batteries pushes practical aqueous Zn-based batteries. However, high Zn utilization achieved in coin symmetric cells is unable to translate to full cells, especially large pouch cells, due to the poor reversibility of Zn and capacity output of high-loading positive electrodes. Here, solid-solid interfacial conversion mechanisms via chelation at electrodes-electrolyte interfaces effectively suppress parasitic reactions being widely prevalent under traditional solid-liquid conversion mechanisms. Consequently, high Zn utilization ( ≥ 78.3%) is unified across coin symmetric, coin full and pouch full cells. The Zn | |I 2 pouch cell (10 cm×10 cm) demonstrates a specific energy of 116.8 Wh kg −1 (based on total mass) and over 850 cycles (85.1% capacity retention) at 10 mA cm −2 . Furthermore, solid-solid interfacial conversion mechanisms exhibit universality across halogen positive electrodes, advancing practical aqueous Zn | |halogen batteries.
