Oral and maxillofacial surgeries or trauma (e.g., impacted tooth extraction, jaw fracture, or tumor resection) often lead to concurrent peripheral nerve injury and bone defects, while current collagen/gelatin sponges offer limited therapeutic effects. To address this challenge, we developed innovative electrospun scaffolds (MOF2, MOF4, and MOF6) by in situ synthesis of 3,5-dihydroxybenzoic acid/zinc (DHBA/Zn-MOF) hybrids within a gelatin/polycaprolactone matrix. In vitro, Schwann cells treated with material extracts exhibited enhanced migration, regulated myelin-associated genes (Ngf/Pmp22 upregulated, Ncam downregulated), and increased NGF protein expression via the PI3K pathway. Co-cultured PC12 cells showed increased neurite outgrowth, confirming neural repair potential. Osteoblasts exposed to material extracts showed elevated alkaline phosphatase activity, enhanced mineralization, and upregulated osteogenic genes (Runx2, Alp, and Opg), verifying osteogenic capacity. In vivo, MOF6 scaffolds achieved superior motor function recovery in a rat sciatic nerve crush model (evidenced by increased compound muscle action potentials and reduced gastrocnemius muscle atrophy) and promoted trabecular bone formation in a rat skull defect model (validated by micro-CT and histological analyses). These findings underscore the dual-functional capability of DHBA/Zn-hybrid scaffolds to simultaneously promote nerve repair and bone regeneration, offering a promising therapeutic approach for complex neuro-bone composite injuries in clinical practice.

SiZnOC gels were coated on C/C substrate by sol–gel, using methyltriethoxysilane (CH 3 Si(OCH 2 CH 3 ) 3 , MTES) and dimethyldiethoxysilane ((CH 3 ) 2 Si(OCH 2 CH 3 ) 2 , DMDES) as precursors, and zinc acetylacetonate (Zn(acac) 2 ) as the modifier. After pyrolysis under argon at 700 °C, SiZnOC ceramics were obtained. Microstructures of SiZnOC with different Zn/Si molar ratios were characterized by FTIR, XRD, SEM and XPS. Biocompatibilities of SiZnOC ceramics were measured by MTT, cell adhesion, antimicrobial activity of Escherichia coli and Staphylococcus aureus, DPPH free radical scavenging and reactive oxygen species (ROS) levels. Vitro bioactivities of materials were evaluated by the generation of bone-like hydroxyapatite (HA) in simulated body fluid (SBF). Results showed that antibacterial and antioxidant properties of SiZnOC enhanced with the content of Zn doping. When Zn:Si molar ratio of SiZnOC increased to 0.4, the inhibition zone diameters were the biggest of 6.7 mm and 5.4 mm for E. coli and S. aureus, respectively, and the scavenging rate was the highest of 88.9% for the DPPH free radicals. However, the level of intracellular reactive oxygen species (ROS) expression was promoted with the increase of Zn doping either. SiOC with Zn:Si molar ratio of 0.2 has the quickest speed of generation bone-like hydroxyapatite (HA) in SBF, on the balance of biocompatibility, bioactivity and antimicrobial performance, SiZnOC with Zn:Si molar ratio of 0.2 was the best for the moderate antimicrobial and antioxidant properties, and the qualified biocompatibility.

Aqueous zinc–iodine batteries (AZIBs) are promising energy storage devices owing to their inherent safety, cost-effectiveness, and high specific capacity. However, their practical application is limited by the shuttle effect of polyiodides and the unstable anode–electrolyte interface of Zn. To simultaneously address these problems, a dual-functional gradient polyanionic hydrogel electrolyte (GPAAS) is developed to stabilize the Zn anode and alleviate polyiodide shuttling. This is achieved via an electric field-induced anionic monomer concentration gradient strategy for anionic monomers. The gradient distribution of anionic groups (−SO3–) within the GPAAS facilitates rapid Zn2+ transport and promotes uniform zinc deposition along the (002) crystal plane. Meanwhile, the high concentration of −SO3– reconfigures the solvation structure of Zn2+ and reduces the number of active water molecules at the zinc electrode interface, thereby stabilizing the anode electrode–electrolyte interface. As a result, the Zn||Zn symmetrical cell exhibits exceptional cycling stability, operating for up to 2100 h at 1 mA·cm–2/1 mAh·cm–2. Moreover, the gradient distribution of −SO3– effectively suppresses polyiodide shuttling through electrostatic repulsion, enhancing iodine utilization and reducing capacity decay. Consequently, ZIBs based on GPAAS achieve a high specific capacity of 203 mAh·g–1 at 0.3 A·g–1 and maintain 80% capacity retention after 1000 cycles at 0.5 A·g–1. This work demonstrates that gradient hydrogel electrolytes provide a viable strategy for the development of stable and high-performance ZIBs.

Self-charging batteries based on organic cathodes and the oxidation mechanism are intriguing because the exhausted battery can be automatically recharged to resume the electrical energy output. A consensus is that the air or dissolved oxygen in electrolyte are indispensable in the self-charging process, which makes the battery impractical due to external air supply and the electrolyte evaporation from non-sealed batteries. Furthermore, organic cathodes generally exhibit low specific capacities. Here, a new self-charging mechanism is realized by blending Pt/C nanocatalysts with poly(1,5-naphthalenediamine, NAPD) to fabricate cathodes for aqueous Zn-polymer batteries. The discharged cathode can be self-charged to 1.16 V within 8 h while being immersed in electrolyte, without the need for dissolved oxygen. This endows a fully sealed coin cell with self-charging function. Owing to the catalytic activation of primary amino groups in poly(1,5-NAPD), the specific capacity is nearly doubled, reaching a high level of 310 mAh g −1 . The role of nanocatalyst in increasing the self-charging rate and voltage is discussed in detail. To demonstrate practical applications, a battery pack is made by loading thick cathodes and Zn anodes into a 3D-printed six-compartment case. This battery pack can be self-charged to 6.4 V and is used to power a walking robot.

Electrochemical CO 2 reduction to syngas driven by renewable energy offers a sustainable alternative to conventional fossil-fuel-based processes, while maintaining a stable H 2 /CO ratio under the inherently fluctuating potentials remains a substantial challenge. In this study, a series of supported Zn catalysts are fabricated by electrodepositing Zn onto Cu foil substrates, with a systematic investigation into the effects of deposition current density (−5 to −20 mA/cm 2 ) and deposition time (10 to 20 min) on catalyst structure and performance. Characterization results reveal that, with increasing deposition parameters, Zn species evolve from discrete nanoplates into an interwoven network of wrinkled structures, accompanied by decreased work function and charge transfer resistance. The synthesized catalysts exhibit a favorable balance in activity toward the electrochemical CO 2 reduction reaction (eCO 2 RR) and hydrogen evolution reaction (HER), thereby enabling highly tunable syngas production with H 2 /CO ratios ranging from 0.5 to 5.4. Notably, the Cu-Zn catalysts demonstrate remarkable stability in syngas composition, maintaining a nearly constant H 2 /CO ratio across a wide potential window of −1.11 to −1.41 V vs. reversible hydrogen electrode (RHE). Furthermore, the Cu-Zn-10–10 catalyst exhibits excellent durability under fluctuating voltage conditions over 24 h, highlighting its potential for seamless integration with intermittent green electricity. In-situ attenuated total reflection surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) and density functional theory (DFT) calculations indicate that the Cu-Zn bimetallic sites moderately enhance *CO adsorption, inhibiting its rapid desorption. Moreover, the energy barriers of eCO 2 RR and HER show little variation with potential, which collectively ensure the stability of the H 2 /CO ratio within the range of −1.11 to −1.41 V vs. RHE.

Diffusion, crossover, and hydrolysis of bromine species in aqueous electrolytes impede the application of Zn||Br batteries with four-electron 2Br + /Br 2 /2Br − conversion. Here, we study a ligand-assisted sparingly solvating electrolyte using ZnSO 4 ·7H 2 O and urea. The high solubility of urea suppresses water activity, while its stronger affinity toward bromine enables preferential coordination over water molecules. This synergistic effect creates a quasi-solvent-free microenvironment that limits bromine solvation and diffusion, resulting in a robust quasi-solid cathode. Moreover, the compact solvation structure favors the formation and stability of Br + species by strengthening nucleophilic urea coordination and inhibiting hydrolysis. Consequently, the fabricated Zn||Br battery exhibits reversible 4e bromine chemistry with a capacity of 417.5 mAh g −1 at 1 A g −1 (based on KBr). A zinc battery coupling the 4e iodine positive electrode and 4e bromine (from the electrolyte) is constructed, yielding a total 8e transfer with a capacity of 897.8 mAh g −1 and a specific energy of 1,344 Wh kg −1 at 2 A g −1 (based on KI).

CS@Zn-MOFs were synthesized via a facile coordination-driven coating method. • The composite shows enhanced colloidal stability and uniform element distribution. • It achieves 91.61% MB removal and high ROS generation under light irradiation. • Effective TC (88.78%) and EM (89.44%) removal via adsorption and AOPs. • Excellent recyclability, stability, high TOC removal, and low cytotoxicity for water treatment. The widespread presence of antibiotics in aquatic environments poses serious ecological and health risks due to their persistence and potential to promote antibiotic resistance. Conventional water treatment processes often fail to remove these micropollutants effectively, highlighting the need for advanced and sustainable remediation strategies. In this study, chitosan‑functionalized zinc‑based metal-organic framework (CS@Zn‑MOFs) with a spindle‑like morphology was developed to enhance photocatalytic removal of antibiotics from water. The composite was synthesized through a coordination-driven self-assembly process followed by CS coating. Comprehensive characterization including SEM-EDS, XRD, XPS, and FTIR, confirmed effective structural integration, homogeneous elemental distribution, and improved colloidal stability. Under light irradiation, CS@Zn-MOFs exhibited exceptional photocatalytic activity, achieving 91.61% removal of methylene blue within 120 min and facilitating substantial generation of reactive oxygen species (ROS). The composite significantly reduced residual levels of tetracycline (TC, 88.78%) and erythromycin (EM, 89.44%), demonstrating efficient antibiotic removal through a synergistic combination of adsorption and advanced oxidation processes (AOPs). Furthermore, CS@Zn-MOFs exhibited excellent recyclability and long-term stability across multiple cycles, coupled with high total organic carbon (TOC) removal efficiency and negligible cytotoxicity. These results collectively demonstrate that CS@Zn‑MOFs are an efficient and stable candidate for the photocatalytic remediation of antibiotic‑contaminated water. This illustration summarizes the design, mechanism, and performance of a novel chitosan-coated Zn-MOFs nanocomposite (CS@Zn-MOFs) for water remediation. The spindle-like Zn-MOFs are functionalized with a chitosan coating through hydrogen bonding and electrostatic interactions, enhancing stability and functionality. Under LED light irradiation, the composite generates abundant reactive oxygen species (ROS), which efficiently purify antibiotic pollutants (e.g., tetracycline and erythromycin) via adsorption and advanced oxidation processes. CS@Zn-MOFs exhibit excellent reusability, long-term stability, coupled with high total organic carbon removal efficiency and negligible cytotoxicity, showcasing great potential as a sustainable and effective photocatalytic material for treating antibiotic-contaminated water.

High-performance SrFe 12 O 19 meets the current demands for lightweight and high-efficiency devices. In this study, Sm‒(Co/Zn/Ca) co-doped spherical SrFe 12 O 19 powders were synthesized via ultrasonic spray pyrolysis. This approach overcomes the limitation of single Sm doping in M-type strontium ferrite, which enhances coercivity but decreases saturation magnetization. The effects of co-doping on the structural and magnetic properties of the material were systematically investigated using X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, Brunauer–Emmett–Teller, Mössbauer spectroscopy, and both room-temperature and low-temperature vibrating sample magnetometry (VSM). Among all the synthesized samples, SrSm 0.20 Zn 0.05 Fe 11.75 O 19 exhibited the highest saturation magnetization ( M s = 78.983 emu/g) while maintaining a coercivity of 7.097 kOe. Compared to SrSm 0.20 Fe 11.80 O 19 , Sm‒Zn co-doping resulted in a 20.12% increase in M s with only a 0.42% reduction in H cj . The results indicate that Zn 2+ preferentially substitutes Fe 3+ at the 4f 2 spin-down sites, reducing the contribution of reverse magnetic moments and thereby enhancing M s . Additionally, as a non-magnetic ion, Zn 2+ does not disrupt Fe‒O‒Fe super-exchange interactions, leading to a minimal reduction in H cj . In contrast, Ca 2+ tends to occupy the 12k and 2a spin-up sites, which reduces spin-up magnetic moments, negatively affecting M s enhancement. Moreover, Co 2+ , being a magnetic ion, disturbs Fe‒O‒Fe super-exchange interactions when incorporated into the SrFe 12 O 19 lattice, leading to a more significant decrease in coercivity. The magneton number ( n B ) calculated from low-temperature VSM confirmed the magnetic moment enhancement effect in the co-doped system, while Mössbauer spectroscopy provided further insights into the hyperfine interactions. This study demonstrates that the Sm‒(Co/Zn/Ca) co-doping strategy effectively balances M s and H cj , significantly improving the magnetic performance of SrFe 12 O 19 . Furthermore, ultrasonic spray pyrolysis proves to be a scalable and cost-effective synthesis method, showing great potential for the large-scale production of high-performance ferrite powders. These findings provide a theoretical foundation for optimizing SrFe 12 O 19 magnetic properties and offer new perspectives for its application in permanent magnet technology.

The practical implementation of zinc (Zn) metal anodes in large-scale aqueous energy storage systems is severely hindered by interfacial instabilities, including dendritic Zn growth, parasitic hydrogen evolution, and self-corrosion. Here, we report a mechanism-driven interfacial design strategy guided by the mass–charge transfer equilibrium within the electric double layer, which dictates the Zn nucleation and growth behavior. Based on this insight, we construct a corrosion-resistant TaF x (TF) interphase via magnetron co-sputtering, which mitigates ion depletion near the Zn surface and promotes spatially uniform Zn electrodeposition. Concurrently, the TF layer elevates the energy barrier for hydrogen evolution and imparts robust corrosion resistance, thereby suppressing interfacial side reactions. These synergistic effects collectively enable planar, dendrite-free Zn deposition and stripping over 1,000 cycles with a high Coulombic efficiency of 99.87%. When integrated into a full-cell configuration with a NH 4 V 4 O 10 cathode, the TF-modified Zn anode retains 82.5% of its initial capacity after 250 cycles at a current density of 0.5 A g -1 . This work establishes a mechanistic framework for interfacial engineering of Zn metal anodes and offers a broadly applicable strategy for stabilizing high-performance AZIBs.

LiMn x Fe 1 − x PO 4 (LMFP) is a promising cathode candidate due to its high working voltage, cost-effective advantages, and environmentally friendly characteristics. However, LMFP is constrained by issues such as low intrinsic electronic and ionic conductivity, as well as Jahn–Teller lattice distortion induced by Mn 3+ , which limit its practical performance. To synergistically optimize its electrochemical behavior, LiMn 0.6 − x − y Fe 0.4 Mg x Zn y PO 4 (x = 0, y = 0; x = 0.005, y = 0.005; x = 0.01, y = 0; x = 0, y = 0.01) composite materials were designed and synthesized via a solvothermal method in this study. A comparative investigation of these samples was conducted to systematically elucidate the mechanisms underlying individual Mg and Zn doping and their synergistic co-doping. The experimental results indicate that the synergistic strategy of Mg and Zn dual-doping combined with carbon coating helps stabilize the olivine structure of LMFP, improves the reaction kinetics, and lowers the Li + diffusion energy barrier. The optimized LMFP/C-MgZn1 exhibits enhanced electrochemical performance, retaining 92.42% of its capacity after 600 cycles at 1.0 C and delivering a discharge specific capacity of 109.8 mAh g −1 at 10.0 C. Furthermore, Density Functional Theory (DFT) calculations indicate that the co-doping strategy improves the reaction kinetics by reducing both the material’s band gap and the Li + diffusion energy barrier. Graphical abstract Mg Zn co doping stabilizes LMFP/C, reduces the Li diffusion barrier and band gap,and enables fast kinetics with durable cycling.

To overcome the difficulty of combining high specific surface area with high metal loading in zinc-based catalysts, we proposed a strategy using adenine for zinc species anchoring and zinc nitrate for in situ pore generation. The environmentally friendly zinc-based catalyst (Zn-NC-800) was synthesized via a solvent-free grinding-assisted pyrolysis, achieving an unprecedented combination of ultrahigh BET surface area (815.28 m²/g) and high Zn loading (4.43 wt%). Zn-NC-800 exhibited excellent bisphenol A (BPA) removal through adsorption-catalysis synergistic enhancement, significantly outperforming other metal-based catalysts (M-NC-800, M= Fe, Mn, Ni). Specifically, Zn-NC-800 achieved an exceptional maximum adsorption capacity of 482.2 mg g⁻¹ for BPA, and the removal rate in Zn-NC-800/PMS system reached almost 100% within 3 min, with the removal rate constant (k obs ) reaching as high as 1.4939 min⁻¹ . Furthermore, the adsorption k obs and removal k obs values showed a strong positive correlation (R² = 0.78), demonstrating the promotion of the adsorption capability of Zn-NC-800 to the pollutants removal within the Zn-NC-800/PMS system. Quenching experiments and electron paramagnetic resonance detection confirmed singlet oxygen (¹O₂) as the dominant reactive oxygen species during peroxymonosulfate (PMS) activation. This study offers guidance on designing environmentally friendly zinc-based catalysts featuring high specific surface area and high metal loading for efficient organic wastewater treatment.

Evolving Zn anodes with high areal capacity at elevated depths of discharge (DOD) is crucial for scalable aqueous battery, yet plagued by dendritic growth and parasitic reactions. Here, we constructed a polymer protective layer (PDMAG@Zn) comprising hydrophobic poly(N,N-dimethylacrylamide) (PDMAA) and zincophilic cationic guar gum (CGG) via an in situ strategy. The moderately hydrophobic property of PDMAA prevents the "Grotthuss" effect on Zn surface to inhibit parasitic reactions while synergistically accelerates Zn2+ desolvation behavior with a molecular lubrication mechanism. Additionally, the PDMAG layer guides Zn2+ deposition along (100) plane for rapid stripping/plating performance. Coupled with CGG-induced interfacial stabilization, the symmetrical batteries achieve ultralong cycling of 6580 h at 1 mA cm−2, 1 mAh cm−2, and 300 h at 1 mA cm−2, 15 mAh cm−2 with 91.5% DODWeight. Furthermore, the Zn||V2O5 full battery delivers a high capacity of 335 mAh g−1 at 1 A g−1, underscoring superior feasibility in practical applications.
