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.

Developing dendrite-free zinc metal anodes with high durability poses a great challenge for aqueous zinc-ion batteries. Herein, we propose an in situ constructed 3D restrained host frameworks with multi-component gradients that induces a controllable and rapid stack-type zinc plating/stripping behavior, enabling a unique “first-in/last-out” mode. Typically, hydrophobic amino-functionalized polysilane passivation layer and zincophilic Ag nanoparticles are successively self-assembled on carbon paper scaffold to form opposite concentration gradients, namely g’ -Ag/ g -PSiO x -NH 2 /CP. The g -PSiO x -NH 2 inhibits side-reactions and promotes Zn 2+ desolvation, meanwhile the g’ -Ag guides preferential Zn 2+ deposition. Consequently, the zinc-deposited g’ -Ag/ g -PSiO x -NH 2 /CP electrodes exhibit high Coulombic efficiency and long cyclability, surpassing 5000 hours at 10 mA cm −2 /10 mAh cm −2 in symmetric cells. The as-assembled Zn||MnO 2 full batteries deliver a specific capacity of 200.1 mAh g −1 with 82.2% retention after 800 cycles. Large-size pouch-type battery with zinc-deposited g’ -Ag/ g -PSiO x -NH 2 /CP anode and high-loading MnO 2 cathode (∼15 mg cm −2 ) also exhibit good rate capability and cyclability. This scalable strategy offers a feasible solution to develop high-durability rechargeable metal-based batteries.

Fusarium wilt, caused by the soil-borne fungusFusarium oxysporumf. sp.lycopersici(Fol), is a devastating disease that severely constrains tomato production worldwide. In this study, an endophytic bacterium, designated ZN-S18, was isolated from healthy tomato stems and identified asBacillus amyloliquefaciensbased on phylogenetic analyses of the 16S rRNA andrpoBgenes. Dual culture assays demonstrated that ZN-S18 exhibited strong antagonistic activity against Fol and significantly inhibited fungal mycelial growth. The cell-free culture filtrate of ZN-S18 markedly suppressed Fol spore germination and mycelial growth, and the inhibitory effect on spore germination was irreversible. LC-MS analyses confirmed that ZN-S18 produces the cyclic lipopeptides surfactin and iturin A. In planta assays further demonstrated that pretreatment with ZN-S18, its culture filtrate, or the combination of surfactin and iturin A significantly reduced Fusarium wilt in tomato seedlings. Moreover, the culture filtrate disrupted fungal cell wall integrity, as indicated by the increased sensitivity of Fol to Congo red stress. Notably, the combined application of surfactin and iturin A exhibited significantly stronger antifungal activity than either compound alone under Congo red-containing conditions, suggesting a synergistic effect on fungal cell wall integrity. Collectively, these findings indicate that the endophytic strainB. amyloliquefaciensZN-S18 is a promising biocontrol agent against tomato Fusarium wilt, primarily through the synergistic action of surfactin and iturin A. This study provides an environmentally friendly alternative to chemical fungicides and establishes a foundation for future investigations into the molecular mechanisms underlying lipopeptide-mediated antagonism.

Biomimetic zinc single-atom nanozymes mimicking natural lactonase were designed. • The nanozyme integrates lactonase, peroxidase, and oxidase-like activities. • Zn-Nx coordination and pore structure govern the multi-enzyme performance. • ZIF-8-Zn-SAC was immobilized onto silicone catheters via an in-situ hydrogel. • The surface exhibits synergistic quorum-quenching and antibiofilm performance. Bacterial biofilms on indwelling medical devices pose a critical challenge due to their intrinsic resistance to antibiotics and host immune defenses. Herein, a zeolitic imidazolate framework (ZIF)-derived zinc single-atom nanozyme (ZIF-8-Zn-SAC) was developed as a multifunctional catalytic material for antibacterial and antibiofilm applications. The atomically dispersed Zn-N x active sites in the N-doped carbon framework provide a biomimetic coordination environment resembling the catalytic center of natural lactonase. ZIF-8-Zn-SAC exhibited integrated lactonase-, peroxidase (POD)-, and oxidase (OXD)-like activities. Its lactonase-like activity enabled efficient degradation of N-acyl homoserine lactone signal molecules, thereby disrupting quorum sensing and suppressing Pseudomonas aeruginosa biofilm formation. Meanwhile, its POD- and OXD-like activities catalyzed the generation of reactive oxygen species from H 2 O 2 and dissolved O 2 , leading to oxidative bacterial damage. Structure-activity relationship analysis indicated that Zn-N x coordination, nitrogen species, and pore accessibility were associated with the multi-enzymatic catalytic performance. As a proof-of-concept surface engineering demonstration, ZIF-8-Zn-SAC was immobilized onto silicone catheter surfaces through an in-situ hydrogel coating strategy. The resulting nanozyme-functionalized surfaces showed effective inhibition of P. aeruginosa biofilm formation, favorable preliminary in vitro biocompatibility, and retained mechanical stability. This work provides a structure-activity-guided strategy for designing multifunctional nanozymes and highlights their potential for antibiofilm surface engineering on polymeric medical interfaces. Schematic illustration of the design and antibiofilm mechanism of ZIF-8-Zn-SAC nanozymes. ZIFs-derived Zn-N x active sites embedded in an N-doped carbon framework provide biomimetic lactonase-like activity for AHLs degradation and quorum-sensing disruption. Simultaneously, the nanozyme exhibits POD- and OXD-like activities, catalyzing ROS generation from H 2 O 2 and dissolved O 2 to induce oxidative bacterial damage. As a proof-of-concept surface engineering strategy, ZIF-8-Zn-SAC was immobilized onto silicone catheter surfaces via an in-situ hydrogel coating, enabling effective inhibition of Pseudomonas aeruginosa biofilm formation on device-relevant polymeric interfaces.

Tunable cation distribution in spinel MCo2O4 enhances surface redox activity. • Microwave-assisted hydrothermal yields ZCO nanosheets and CCO nanorods with defects. • Oxygen vacancies and mixed cations boost interfacial charge transfer kinetics. • CCO/SPE shows high sensitivity and low LOD for Carbendazim detection. • Strong Carbendazim adsorption on spinel surfaces confirmed by experiment and theory. Spinel cobaltites MCo 2 O 4 (M is a divalent metal ion) nanomaterials have emerged as promising electrocatalysts for electrochemical sensing owing to their tunable cation distribution and redox-active metal centers. In this work, ZnCo 2 O 4 (ZCO) nanosheets and CuCo 2 O 4 (CCO) nanorods were prepared using a simple microwave-assisted hydrothermal method and subsequently employed to modify screen-printed electrodes (SPEs) for carbendazim (CBZ) detection. Structural analysis revealed distinct cation arrangements within the spinel lattice, particularly CCO exhibited mixed Cu/Co occupancy and abundant oxygen vacancies. Both modified electrodes significantly enhanced the electrochemical oxidation of CBZ compared with bare SPE, primarily due to the catalytic activity of the Co 3+ /Co 2+ redox couple. Notably, the CCO/SPE demonstrated superior sensing performance, arising from the synergistic effects of Cu 2+ /Cu + redox activity, high defect density, and one-dimensional morphology that promoted charge transfer and mass diffusion. The CCO/SPE sensor delivered promising analytical performance, featuring two linear ranges (0.1–10 and 10–500 µM), a detection limit of 0.07 µM, and a sensitivity of 5.97 µA µM −1 cm −2 . Combined experimental and theoretical analyses suggest strong CBZ adsorption on the MCo 2 O 4 spinel surface, highlighting spinel oxides as efficient electrocatalysts for CBZ pesticide sensing.

PdZn/Mo-Al 2 O 3 -C effectively catalyzed hydrodeoxygenation (HDO) of fatty acid esters to alkanes. • Coexistence of Pd and Zn enhanced the dispersion of active sites and regulates the distribution of acid sites. • ZnO x and MoO x species adjacent to Pd suppressed the decarboxylation side reaction. • 92% octadecane selectivity was achieved in methyl stearate HDO. The conversion of fatty acid esters to alkanes with high carbon chain number by hydrodeoxygenation (HDO) is of great significance in biomass conversion to fuels and chemicals. A PdZn/Mo-Al 2 O 3 -C catalyst was prepared for the preparation of octadecane from methyl stearate HDO. The coexistence of Pd and Zn on Mo-based catalysts greatly promoted the dispersion of active sites on the catalyst surface, which also effectively regulated the distribution of acid sites on the catalyst surface. The Zn modified Pd catalyst also effectively adsorbed the C O/C–O bond of the substrate to facilitate the cleavage of C–O bonds, as well as suppressing the decarboxylation side reaction, and achieving octadecane selectivity of 92%. The optimized catalyst also displayed high HDO selectivity for converting the fatty acid esters (C 8 ∼ C 18 ) to alkanes. Download: Download high-res image (166KB) Download: Download full-size image

Introduced Co 2+ increases the structural stability of δ-MnO 2 and enlarges the interlayer spacing, promoting ion diffusion. • δ-MnO 2 @Co/TCT further improves the electrical conductivity, ameliorates the agglomeration problem and increases the electrochemical reaction active area. • Synergistic improvement of electrochemical performance through the strategy of ion doping and introduction of conductive materials, Zn//δ-MnO 2 @Co/TCT full cell with 1000 stable cycles at 1.5 A g -1 . δ-MnO 2 is considered a highly promising cathode material for aqueous zinc-ion batteries (AZIBs). However, its practical application is hindered by two critical issues: delayed transport kinetics and insufficient structural stability. Therefore, a synergistic strategy involving Co 2+ doping and composite coating with Ti 3 C 2 T x MXene (TCT) nanosheets was designed and implemented to achieve effective doping of the δ-MnO 2 lattice with Co and to ensure uniform loading of the active component onto the TCT substrate surface, ultimately leading to the successful fabrication of the δ-MnO 2 @Co/TCT composite material. First, the incorporation of Co 2+ as interlayer pillars effectively widens the interlayer spacing of δ-MnO 2 , thereby enhancing its structural stability and enabling faster ion embedding/de-embedding. Second, the TCT conductive substrate effectively mitigates the agglomeration of δ-MnO₂@Co, significantly increasing the electrochemical reaction area. Benefiting from the unique composite structure design, the Zn//δ-MnO 2 @Co/TCT full cell exhibits significantly optimized electrochemical performance. The assembled cell delivers a high specific capacity of 239.5 mAh g −1 at 0.5 A g −1 , and maintains outstanding cycling stability over 1000 cycles at 1.5 A g −1 . Result indicates that comprehensive performance of cathode materials can be effectively enhanced by multilevel structural synergistic design, providing a feasible technological pathway for development of high-performance AZIBs.

Sodium metal batteries (SMBs) are regarded as promising candidates for next-generation energy storage technologies due to their high energy density and low cost yet remain challenging owing to dendritic sodium deposition, unstable electrode–electrolyte interfaces, and sluggish ion transport, particularly under fast-charging conditions or at low operating temperatures. To address these challenges, in this study, we introduce Sn-Zn atomic configured porous, nitrogen-rich carbon-based meta-material (SA-NCS), derived from a guanine-based hydrogen-bonded organic framework (HOF), serving as sodium host material for SMBs, which provides a high density of atomic sodiophilic sites to promote the transition from one-dimensional dendritic deposition to two-dimensional planar-oriented dense plating, and features programmable nano-to-macro functional structures capable of effectively accommodating the anodic volume fluctuation induced by sodium plating and stripping. SA-NCS@Cu current collector exhibits an ultralow nucleation overpotential of 22 mV even at a high current density of 20 mA cm −2 and delivers exceptional cycling stability, enabling stable operation for 2000 h at 10 mA cm −2 with Coulombic efficiencies exceeding 99.9%. Moreover, the SA-NCS @Cu current collector based anode-less sodium metal batteries demonstrate a superior fast-charging capability and long-term cycling stability at −20°C. This study presents a practical design for sodium hosts, enabling high-performance SMBs.

The rapid increase of battery and carbon waste has raised an urgent demand for efficient recycling methods, along with the development of environmentally friendly energy storage materials. In this study, zinc ferrite (ZnFe2O4, ZFO) was synthesized from spent batteries, while graphene nanosheets (GNs) was obtained from recycled carbon, and then combined to form ZFO@G composites for supercapacitor applications. Characterization techniques including XRD, Raman, SEM, and electrochemical analyses (CV, GCD, EIS) were employed to elucidate the crystal structure, surface morphology, and electrochemical performance of the materials. The results reveal that the incorporation of GNs improves the electrochemical performance of ZFO, delivering a specific capacitance of 606.69 F g–1 at 1 A g–1 with a capacitance retention of ∼58.8% after prolonged cycling. This study not only demonstrates the potential of recycled materials for supercapacitor applications but also contributes to mitigating environmental issues caused by battery waste.

Robust Co 2 N/N-doped carbon catalyst derived from sustainable ginger biomass. • Synergistic coupling and tuned electronic structure boost reaction kinetics. • Superior bifunctional activity (ORR: 0.83 V, OER: 1.48 V @ 10 mA·cm −2 ). • Excellent stability and methanol tolerance. • Practical Zn-air battery performance validates real-world applicability. The development of efficient and cost-effective bifunctional electrocatalysts for oxygen reduction and evolution reactions (ORR/OER) is essential for rechargeable metal-air batteries and reversible fuel cells, yet remains challenging. Cobalt nitrides (Co x N) coupled with nitrogen-doped carbon have shown promise as bifunctional catalysts, but achieving high performance for both reactions via sustainable synthesis remains difficult. Herein, we report a Co 2 N nanoparticles-embedded N-doped porous biomass-derived carbon catalyst (denoted as Co/NGGC) that addresses this challenge, exhibiting markedly enhanced bifunctional activity compared to previously reported Co x N/N‑carbon systems. The optimized Co/NGGC achieves a low potential gap (ΔE) of 0.65 V between the ORR and OER. For the ORR, the resulting catalyst demonstrates superior activity, excellent durability and robust methanol tolerance, compared with the commercial Pt/C (20 wt% Pt). For the OER, Co/NGGC can drive current density of 10 mA·cm −2 at an ultralow overpotential of 250 mV, significantly outperforming RuO 2 . More importantly, the alkaline zinc-air battery (ZAB), assembled with Co/NGGC as the cathode, demonstrates high peak power density and excellent stability, underscoring its practical applicability. The enhanced electrocatalytic performance is attributed to the strong coupling between the Co 2 N nanoparticles and the nitrogen-doped carbon framework, which creates a synergistic microenvironment that accelerates electron transfer and facilitates mass diffusion. Density functional theory (DFT) calculations further reveal that the electronic states of Co 2 N near the Fermi level are significantly elevated within the N-doped carbon matrix, optimizing the adsorption/desorption behavior of key reaction intermediates and thereby accelerating the overall reaction kinetics. This work not only presents a sustainable strategy for converting biomass into efficient electrocatalytic materials but also provides valuable insights into the design of advanced oxygen electrodes for next-generation energy conversion and storage devices.

Conventional solid-state sintering of M-type hexaferrites requires high temperatures and long durations yet often yields inadequate density and coarse grains, limiting functional performance. This limitation is overcome by hot pressing, which applies uniaxial pressure synergistically with a transient liquid phase. This strategy enables rapid densification at a substantially lower temperature of 975 °C, in contrast to over 1100 °C for conventional methods. The resulting ceramics achieve near theoretical density exceeding 98% (98.03-98.22%), a fine-grained uniform microstructure, and superior structural integrity ( R wp = 2.50-2.83%), properties unattainable by standard sintering. The hot-pressing process also leads to oxygen vacancy reorganization. Consequently, the materials exhibit comprehensively enhanced properties: the optimal composition achieves a high coercivity of 1672.8 Oe, and low dielectric loss (ε″ ≈ 0.93 at 1 MHz) with excellent temperature stability (Δε' as low as 9.23). This work establishes hot pressing as a superior alternative and elucidates the underlying pressure assisted densification and valence modulation mechanism, providing a new design principle for engineering high performance microwave ferrites.

Electrolytic zinc–manganese batteries (ZMBs) featuring high energy density and low cost hold significant potential for large-scale energy storage. However, their development is hindered by severe zinc corrosion and poor reversibility of the Mn2+/MnO2 conversion, originating from drastic pH fluctuations and an acidic environment. Herein, we propose an organic/inorganic self-stratifying electrolyte, which synergizes with the self-sacrificial sustained-release Zn(BF4)2 to regulate the zinc interface and MnO2 conversion chemistry. The design innovatively utilizes the in situ hydrolysis of BF4– to create an HF/F– buffer and free F– ions. The former stabilizes cathode pH and promotes uniform deposition and deep conversion of MnO2. Additionally, the released F– fosters a robust ZnF2-rich SEI on the zinc anode in a water-lean environment (organic phase), effectively suppressing corrosion and side reactions. Therefore, the zinc-symmetric battery with an organic phase exhibited a lifespan of over 650 h, exceeding conventional aqueous electrolytes by 38-fold. The Zn–MnO2 batteries deliver exceptional stability for 1800 cycles at 2C with an average Coulombic efficiency of 98.7%. This biphasic buffering-interface regulation strategy provides a generalizable approach to decouple interfacial challenges, which is promising for extension to other corrosion cell systems.
