Aqueous Zn||I 2 batteries provide advantages in terms of safe operation and economical energy storage, yet their practical deployment is markedly constrained by the insufficient capacity of conventional two-electron iodine redox chemistry and the unfavorable interfacial reactions at the Zn surface. Herein, a coupled electrolyte regulation strategy is reported that incorporates choline chloride (ChCl) and acrylamide (AM) into the ZnSO 4 electrolyte, enabling comprehensive regulation from the anode to the cathode. This design not only facilitates reversible high-valence iodine chemistry via the formation of stable ICl intermediates but also induces in situ generation of a distinctive PAM-Ch + solid electrolyte interphase (SEI) on the Zn surface. As a result, durable multielectron iodine redox chemistry is realized in aqueous Zn||I 2 cells while preserving high Zn anode reversibility. The Zn anode operates stably for over 5000 h at room temperature, while the Zn||I 2 full cell delivers a specific capacity of 340.83 mAh g −1 at 1 A g −1 and retains 81.2% of the capacity after 6000 cycles at 5 A g −1 . This work offers a strategy to reconcile multielectron iodine conversion with Zn anode interphase stability, providing guidance for high-energy-density aqueous battery design.

Charging P2-type Na 0.66 Ni 0.33 Mn 0.67 O 2 (NNM) to a high upper cut-off voltage of 4.3 V (vs. Na + /Na) can yield a competitive discharge voltage (3.6 V-class) and capacity. However, achieving stable cycling for NNM under this condition remains challenging owing to an unfavorable phase transition and a large lattice-volume change. Herein, a dual-site doping strategy is used to simultaneously realize a pinning effect at the Na and transition metal sites. Incorporating pinned K + and Zn 2+ ions considerably enhances the structural stability of NNM, affording a complete single-phase reaction with ultralow strain (only 0.54 % variation in volume) during Na + insertion/extraction. The synergistic contributions of dual-site doping to the enhanced electronic conductivity , lowered Na + migration barrier, and increased Na + diffusion coefficients are confirmed via theoretical calculations. Consequently, the K + /Zn 2+ dual-site-doped Na 0.63 K 0.03 Ni 0.26 Zn 0.07 Mn 0.67 O 2 delivers satisfactory discharge capacities of 118.6 and 63.2 mAh g −1 at 10 and 2000 mA g −1 , respectively, and achieves an excellent capacity retention of 81.2 % after 200 cycles at 500 mA g −1 . This study provides a promising method to strengthen the stability of the Ni − Mn-based layered framework and optimize other high-voltage and high-capacity layered oxide cathode materials .

Photodynamic therapy (PDT) holds promise for oral squamous cell carcinoma (OSCC) but is limited by the tumor microenvironment─specifically hypoxia, elevated glutathione (GSH), and the lack of tumor-selective photosensitizer activation. To overcome these barriers, we developed a GSH-activated nanoplatform Cu-TCPP(Zn)/Ti3C2Tx for fluorescence imaging-guided synergistic photodynamic/chemodynamic therapy (PDT/CDT). The system is constructed from two-dimensional Cu-TCPP(Zn) MOF nanosheets, where Cu2+ and Zn2+ completely quench the fluorescence and PDT activity of TCPP and surface-anchored Ti3C2Tx MXene. In the TME, overexpressed GSH reduces Cu2+ to Cu+ and abstracts Zn from the Zn–N4 complex, triggering nanocomposite disintegration to restore fluorescence, activate PDT, and simultaneously deplete GSH to reduce antioxidant defense. The resulting Cu+ catalyzes a Fenton-like reaction with endogenous H2O2 to generate •OH for CDT, while Ti3C2Tx acts as a catalase-like nanozyme, decomposing H2O2 into O2 to alleviate hypoxia, promote charge transfer, improve the utilization efficiency of photogenerated electrons, and enhance PDT efficacy. In vitro, the platform showed excellent biocompatibility and GSH-responsive activation, inducing 41.21% apoptosis in CAL-27 cells under 660 nm laser irradiation, significantly outperforming controls. In vivo, the nanocomposite accumulated efficiently in tumors via the EPR effect, suppressed tumor growth, and exhibited no observable systemic toxicity. This work provides a TME-responsive theranostic platform that integrates tumor-specific activation, GSH depletion, hypoxia alleviation, and enhanced ROS generation for precise and effective OSCC treatment.

Regulating the coordination structure of single-atom catalysts (SACs) is an effective strategy to enhance oxygen reduction reaction (ORR) activity and zinc-air battery (ZAB) performance. However, asymmetric coordination configurations often suffer from poor structural stability during long-term operation, limiting their practical applicability. To address this challenge, this study introduces a Co single-atom catalyst (Co-SAs/N V PC) featuring a shell-structured architecture with strategically positioned pyridinic-N vacancies adjacent to stable Co N 4 sites. The introduction of vacancies shifts the d-band center of Co closer to the Fermi level, weakening the binding strength of *OH and thereby enhancing both the activity and selectivity of the ORR, as confirmed by in-situ surface-enhanced Raman spectroscopy (SERS) and Fourier-transform infrared (FTIR) analyses. Temperature- and potential-dependent scanning electrochemical microscopy (SECM) further offers deeper insights into the dynamic catalytic behavior under operational conditions. When integrated into ZABs, Co-SAs/N V PC delivers a peak power density of 203.4 mW cm −2 , a specific capacity of 775 mAh g −1 , and sustains 58% capacity retention after 1000 cycles at 10 mA cm −2 . This work establishes a design paradigm for SACs in sustainable energy systems by bridging atomic-scale electronic tailoring with macroscopic energy conversion efficiency.

The development of efficient bifunctional catalysts for oxygen reduction and evolution reactions (ORR/OER) is crucial for advancing rechargeable zinc-air batteries (ZABs). Herein, we report a three-dimensional N-doped CoFe alloy embedded in hierarchical carbon (Co x FeN@3D-GC) as a high-performance catalyst. This unique architecture, synthesized via a one-pot pyrolysis process, integrates in-situ grown carbon nanotubes grafted onto reduced graphene oxide sheets, with CoFe nanoparticles uniformly dispersed within the matrix. The Co x FeN@3D-GC catalyst exhibits outstanding bifunctional activity, achieving a half-wave potential of 0.935 V for ORR and an overpotential of only 298 mV at 10 mA cm −2 for OER, rivaling the performance of noble-metal benchmarks (Pt/C and RuO 2 ). When deployed in a practical ZAB, it delivers a peak power density of 246 mW cm −2 , a specific capacity of 815 mAh g −1 , and remarkable stability over 800 cycles. Combined experimental and theoretical analyses reveal that the superior performance originates from the synergistic interplay among the bimetallic CoFe heterostructure, the hierarchical conductive network, and the N-doped carbon matrix, which collectively optimize charge transfer, mass transport, and reaction kinetics.

The increasing demands in optoelectronic applications have driven the advancement of organic–inorganic hybrid metal halides (OIHMHs), owing to their exceptional optical transparency and high luminescence performance. In this work, three zero-dimensional OIMH single crystals of (C7H18N2)MBr4 (C7H18N2 = 1-propylpiperazine, M = Cd, Zn, and Mn) were prepared via a facile saturated crystallization method with adjustable luminescence properties. (C7H18N2)MnBr4 displays intensive green light emission with the highest photoluminescence yield (PLQY) of 54.93% originating from the d–d transition of Mn2+. Due to filled d orbital configurations of Zn2+ and Cd2+, (C7H18N2)CdBr4 and (C7H18N2)ZnBr4 exhibited blue light owing to their stronger self-trapped excitons (STEs) recombination. Furthermore, (C7H18N2)CdBr4 and (C7H18N2)ZnBr4 exhibited another red luminescence band after grinding, originating from defect-induced STEs. In addition, due to their excellent PL performance, the white LED fabricated based on (C7H18N2)MnBr4 and (C7H18N2)ZnBr4 has demonstrated a high color rendering index (CRI) of 88.2. This work not only provides a strategy for optimizing the photoluminescence performance by modulating metal ions within the same crystal structure of OIHMHs, but also provides insights into both intrinsic STE emission and the design of high-performance luminescent materials.

Aqueous zinc-iodine (Zn-I 2 ) batteries have garnered significant attention owing to their high theoretical capacity and intrinsic safety. However, their development is still hampered by sluggish iodine redox kinetics and severe capacity decay caused by the polyiodide shuttle effect. To systematically address these challenges, we report a multifunctional self-supporting cathode (Ni-CNT/NFC@I) integrating nickel-functionalized carbon nanotubes (Ni-CNTs) with nanofibrillated cellulose (NFC). The Ni-CNTs serve a dual role: catalytically accelerating iodine redox kinetics while chemically anchoring polyiodides. Concurrently, the NFC backbone provides mechanical flexibility and forms a 3D porous network for physical confinement. This synergistic catalytic anchoring and physical confinement strategy effectively suppresses the shuttle effect. Consequently, the cathode delivers a high capacity of 210.1 mAh g −1 (99.6% iodine utilization) and demonstrates exceptional cycling stability, retaining 94.0% of its capacity after 5000 cycles at 3.0 A g −1 . The multifunctional self-supporting electrode design concept proposed in this study offers a new strategy for the development of long-lifespan, high-stability aqueous energy storage devices.

The plasma catalytic direct oxidation of methane into the value-added chemical methanol over LaZnAl catalyst was investigated under mild condition. The synergistic effect between plasma and the LaZnAl catalyst was achieved. The electronic interaction of La-Zn facilitated the formation of oxygen vacancies, and promoted the utilization of the plasmaactivated O radicals, and enhanced the formation rate of the key intermediate CH3O species, thereby leading to low apparent activation energies for methane conversion and methanol production. The interaction of La-Zn species resulted in a significantly enhanced contribution of 89.6% to methanol formation, whereas the contribution of Zn alone was only 23.7%, and that of La was even negative (-32.9%). Consequently, methanol production was markedly improved and a methanol selectivity of 40.9% was achieved over the LaZnAl catalyst, compared to 26.7% for ZnAl and 14.5% for LaAl.

The clinical translation of mRNA vaccines for cancer immunotherapy critically hinges on the development of mRNA nanocarriers that ensure precise organ targeting, potent immune activation, and high biosafety. Here, we reported the novel supramolecularly engineered mRNA nanocarriers based on Zn 2+ -lipid nanoparticle (LNP) coordinated nanoassemblies (NAs), incorporating imidazole-functionalized ionizable lipids and Zn 2+ ions as structural and immunostimulatory components. Specifically, a library of 32 imidazole-based ionizable lipids was synthesized and screened, identifying BR5–2 LNPs as a lead candidate for efficient mRNA transfection. By leveraging the coordination interaction between Zn 2+ and the components of BR5–2 LNPs, we successfully constructed Zn-BR5–2 NAs, which exhibited enhanced in vitro mRNA transfection efficiency and promoted dendritic cell maturation via upregulation of major histocompatibility complex class I (MHC-I) antigen presentation. In vivo , Zn-BR5–2 NA-based vaccines achieved 82% spleen-specific mRNA expression and induced a strong antigen-specific CD8 + T cell response (23.09%). Notably, in a B16-OVA mouse melanoma model, Zn-BR5–2 encapsulating ovalbumin mRNA (Zn-BR5–2/mOVA) elicited potent prophylactic and therapeutic antitumor effects. This work underscores the potential of metal-LNP coordination chemistry in advancing next-generation mRNA vaccines with organ-specific delivery and heightened immunotherapeutic efficacy.

The design and development of cost-effective and highly efficient bifunctional oxygen electrocatalysts hold great significance in the study of metal-air batteries. Herein, the present study describes a facile and scalable strategy for the synthesis of a complex comprising nanorod-like MnO 2 -V O integrated with MWCNTs. For electrochemical performance, MnO 2 -V O /MWCNTs exhibit excellent oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalytic activities, demonstrating a half-wave potential ( E 1/2 ) of 0.79 V for ORR and a potential of 1.62 V at 10 mA cm −2 for OER, with a low bifunctional potential difference ( ΔE OER-ORR , between the ORR half-wave potential and the OER potential at 10 mA cm −2 ) of 0.83 V, which are comparable to those of Pt/C and RuO 2 . This excellent catalytic performance can be attributed to the rational design of the MnO 2 -V O components and the unique interwoven network of the MnO 2 -V O /MWCNTs complexes. In addition, the electrocatalytic action and stability improvement mechanisms were also systematically analyzed based on microstructural characterization and electrochemical response. Finally, a zinc-air battery (ZAB) was fabricated by employing the as-synthesized MnO 2 -V O /MWCNTs as the cathode catalyst. The MnO 2 -V O /MWCNTs-based ZAB demonstrates an open-circuit voltage of 1.48 V, a power density of 71.17 mW cm −2 , and superior charge-discharge cycling stability with a voltage gap of only 0.77 V after 100 cycles, which are comparable to those of the commercial Pt/C + RuO 2 -based ZAB (1.39 V, 74.84 mW cm −2 , and 0.87 V gap). This study provides a simple, inexpensive and accessible synthetic method for the design of high-performance non-precious metal-based ORR/OER bifunctional electrocatalysts.

Cross-substrate counter diffusion (CSCD) between imidazole and Zn(II)-loaded polyamide (PA) layers is carried out to in-situ grow zeolitic imidazole framework-leaf (ZIF-L) particles and improve the nanofiltration (NF) performances of negatively charged NF membranes. To achieve uniform distribution of Zn(II) in the formed PA layer, Cyclen was used to complex Zn(II) precursors during the interface polymerization (IP) between piperazine (PIP) and trimesoyl chloride (TMC) to dissolve the Zn(II)/PIP precipitation in the aqueous phase. Results showed that the addition of Cyclen improved the uniform dispersion and firm combination of ZIF-L particles (PTs) in the PA layers, improving both the water permeance and salt rejection of the formed TFN NF membranes. Under optimal conditions, TFN-PC 0.10-0.15 /ZIF membrane achieves a Na 2 SO 4 rejection of 90.2-96.8%, a pure water permeance of 25.8-32.8 L·m -2 ·h -1 ·bar -1 , a NaCl/Na 2 SO 4 mixed salt separation factor of 9.0-29.8, and good anti-fouling and operational stability.

A novel in situ self-sulfidation approach was devised to fabricate ZnO/ZnS/C ternary nanocomposites as highly stable anodes for alkaline Zn–Ni batteries. Zinc sulfate acted as a dual-purpose precursor, providing both zinc and sulfur, whereas acrylamide served as the carbon source and in situ reductant. In a single-step carbothermal pyrolysis at 800 °C, the carbon matrix converted sulfate ions to sulfide, facilitating the simultaneous generation of electrochemically active ZnO, a protective ZnS layer, and a conductive carbon network during a single thermal treatment. The optimized ZnO/ZnS/C-2 electrode exhibited a discharge capacity of 576.8 mAh g −1 after 600 cycles at 1 C and maintained 513.2 mAh g −1 at 15 C. Under identical conditions at 10C, the ZnO/ZnS/C-2 electrode delivered a capacity of 545.3 mAh g −1 , which is 41.5% higher than that of commercial ZnO (385.4 mAh g −1 ). Upon the current density reverting to 0.2 C, it regained 96.6% of its original capacity, indicating remarkable reversibility. Post-cycling scanning electron microscopy images validated the successful inhibition of zinc dendrite proliferation. The performance improvements arise from the synergistic combination of the protective ZnS layer, the interconnected conductive carbon framework, and the advantageous ZnO/ZnS heterointerface, which collectively boost structural stability and charge transfer kinetics.
