The advancement of aqueous zinc-ion batteries (AZIBs) is impeded by challenges encompassing cathodic and anodic aspects, such as limited capacity and dendrite formation, constraining their broader utilization. Herein, pyrrole, an economically viable and readily accessible compound, is proposed as a versatile electrolyte additive to address these challenges. Experiments and DFT calculations reveal that pyrrole and its derivatives preferentially adsorb onto zinc foil, facilitating the formation of a pyrrole-based solid electrolyte interphase (SEI), which effectively guides uniform Zn 2+ deposition through strong attraction force and suppresses hydrogen evolution reactions and parasitic reactions. On the cathode side, the additive promotes the formation of a durable cathode electrolyte interphase (CEI) enriched with poly-pyrrole (Ppy) analogues. Such layer significantly contributes to extra capacity of both polyaniline (PANI) and MnO 2 cathodes by leveraging the electrochemical reactivity of Ppy towards Zn 2+ and improves their cyclic stability. Consequently, a dendrite-free Zn anode is realized with an extended cyclic lifespan surpassing 6000 h in Zn//Zn cell, coupled with an average Coulombic efficiency of 99.7 % in Cu//Zn cell. Moreover, the PANI//Zn and MnO 2 //Zn full cells demonstrate enhanced capacities along with improved cycling stability. This work provides a new additive strategy towards concurrent stabilization of cathode and Zn anode in AZIBs.

In this study, single-phase high-entropy ceramics (HECs) with the composition (Co,Mn,Fe,Zn,Ni,Mg,Al,Cr) 3 O 4 were successfully synthesized using five different types of spinel raw materials. The resulting material demonstrates excellent performance in the negative temperature coefficient (NTC) thermistor field. X-ray diffraction (XRD) analysis confirmed the structure as a cubic spinel with a single Fd-3m space group. The electron microscope image reveals the growth of ceramic grains with increasing sintering temperature, with a uniform distribution of all elements. After 1800 h of accelerated aging at 150 °C, the Δ R / R 0 value was only 0.41 %, indicating the ceramic's exceptional structural stability. X-ray photoelectron spectroscopy(XPS) analysis reveals that electrical conductivity are mainly governed by electron hopping between Mn 3+ and Mn 4+ ions in the octahedral sublattice sites. Impedance spectroscopy further shows that grain boundary resistance is the dominant contributor to the total resistance. This study provides new insights into the synthesis of single-phase HECs materials and proposes strategies to enhance material stability for future applications.

Developing effective strategies to improve the electrocatalytic activity of carbon-based materials is significant for Zn-air batteries (ZABs). Herein, nitrogen-doped carbon with abundant sp3-hybridized carbon defects (NC-CTS) were synthesized through a nonthermodynamic equilibrium carbonization process called carbon thermal shock (CTS). The NC-CTS catalyst exhibited a superior oxygen reduction reaction (ORR) activity with a half-wave potential of 0.81 V vs RHE and good stability in alkaline electrolyte, exceeding the NC-Furnace catalyst, which was fabricated by a thermodynamic equilibrium process. The better ORR performance originated from the increased density of sp3-hybridized carbon defects as the active sites and the optimized adsorption energy of intermediate species. The sp3-hybridized carbon defects were attributed to the obstruction of atom mobility and aggregation due to the ultrashort duration time of CTS. Furthermore, the ZABs using NC-CTS catalysts as the cathode showed good discharge performance and high cycling stability with a power density of 110 mW cm–2. This study demonstrated an effective strategy to modulate the ratio of sp3/sp2 of carbon-based electrocatalysts for the development of advanced carbon-based electrocatalysts to enhance the ORR performance and for the development of ZABs.

Dendrite-free Zn metal anodes with high depth-of-discharge (DoD) and robust cycle performances are highly desired for the practical application of aqueous Zn-ion batteries. Herein, the zincophobic/hydrophilic nature of Metal-N-C through manipulating the electronic interactions between metal and coordination atoms is successfully reversed, thereby fabricating a zincophilic/hydrophobic asymmetric Zn-N 3Py+1Pr -C (consisting of a Zn center coordinated with 3 pyridinic N atoms and 1 pyrrolic N atom) host, which realizes uniformed Zn deposition and a long lifespan with high DoD. The experimental and theoretical investigations demonstrate weakened interaction between pyrrolic N and metal center in the asymmetric Zn-N 3Py+1Pr -C triggers downshift of the Zn 3d-band-center and a new localization nonbonding state in the N and C 2p-band, resulting in preferred Zn adsorption to water adsorption. Consequently, the asymmetric Zn-N 3Py+1Pr -C host delivers small Zn nucleation overpotential and high Coulombic efficiency of 98.3% over 500 cycles. The symmetric cells with Zn-N 3Py+1Pr -C@Zn anode demonstrate 500 h dendrite-free cycles at DoD up to 50%. The Zn-N 3Py+1Pr -C@Zn/S-PANI full cell also shows a robust long-term cycle performance of 1000 cycles at 10 A g −1 . This strategy of constructing zincophilic/hydrophobic Metal-N-C may open up their application for the dendrite-free metal anode.

It is desirable but challenging to develop low-cost and high-performance electrocatalysts for the oxygen evolution reaction (OER) in zinc–air batteries (ZABs) applications. In this work, a series of cerium oxide-coated cobalt vanadium oxide nanoplates (denoted as CVO@CeO 2 ) are prepared using different CeO 2 loadings through a facile two-step method. Compared to bare CVO, CeO 2, and commercial RuO 2 , the CVO@CeO 2 -0.20 catalyst presents much higher activity toward OER in alkaline solutions. Moreover, the CVO@CeO 2 -0.20 also exhibits superior open-circuit voltage and durability when utilized as the cathode in ZABs. Both theoretical calculations and experimental results disclose that the decoration of CeO 2 on CVO not only regulates the formation of high-spin state Co 3+ , optimizing the absorbate evolution mechanism (AEM) pathway, but also activates lattice oxygen, enhancing the lattice oxide oxidation mechanism (LOM) pathway. This research presents the CVO@CeO 2 heterojunction as an excellent catalyst for the OER and proposes a promising interface-regulated strategy for developing catalysts based on the reinforcement of AEM and LOM mechanisms.

Detrimental dendritic lithium (Li) growth, infinite volume expansion of Li deposition and inevitable excess electrolyte consumption have always impeded the successful application of Li metal anodes. Herein, a unique lithiophilic vertical cactus-like framework (LVCF) derived from a Zn/Cu-based coordination polymer through in situ chemical etching of Cu foam is proposed to enhance the safety and electrochemical performance of Li metal anodes. An ingenious strategy of releasing Cu ions from Cu foam in the presence of organic ligands is implemented successfully to achieve the coordination polymer precursor, resulting in the coexistence of massive lithiophilic nitrogen-containing functional groups, ZnO quantum dots and in situ grown carbon nanotubes (CNTs) in the LVCF, which is beneficial to avoiding the generation of harmful Li dendrites. Benefiting from the positive effects of the improved lithiophilicity, decreased local current density and relieved volume expansion, LVCF delivers an ultrastable Coulombic efficiency of 98.6% for 600 cycles at 1 mA cm –2 and an improved cycling lifespan of 1800 h for symmetric cells. Full cells comprising LVCF@Li anodes and LiFePO 4 cathodes can deliver an ultrahigh capacity of 101.8 mAh g –1 (capacity retention ratio: 77.9%) after 900 cycles at 1 C and excellent rate performance.

MicroRNAs are remarkably stable and detectable, making them ideal candidates for non-invasive diagnostics. The clinical relevance of fluid-specific miRNA profiling has implications for early disease detection, prognostic prediction, and therapeutic monitoring. A novel colorimetric biosensor for the highly sensitive detection of miRNA-21 is presented, integrating a dual catalytic hairpin-based cyclic self-assembly reaction system with Zn@HRP snowflake metal-organic frameworks (MOFs). This system leverages the unique snowflake structure and high catalytic activity of Zn@HRP MOF for signal amplification. Upon target miRNA-21 recognition, the system undergoes a cascade amplification process, leading to a significant increase in absorbance that is directly proportional to miRNA-21 concentration. The developed biosensor exhibits an ultra-low detection limit of 0.27 fM, demonstrating exceptional sensitivity, specificity, and anti-interference capabilities. Furthermore, the biosensor performs robustly in complex plasma samples, showing reliable recovery rates and excellent correlation with qRT-PCR results. This work not only provides a robust platform for precise miRNA detection but also offers significant potential for clinical diagnostics and biomarker profiling, paving the way for more accessible and reliable diagnostic tools in personalized medicine.

Osteoporotic bone defects remain a major clinical challenge due to impaired osteogenesis, insufficient angiogenesis, excessive osteoclast activity, and increased susceptibility to infection. To address these issues, we developed an injectable phosphocreatine-grafted gelatin hydrogel (GGP) incorporating hierarchically structured Zn-Cu particles functionalized with a teriparatide (PTH)/strontium–zinc phosphate (SrZnP) hybrid coating. This multifunctional hydrogel was fabricated via enzymatic and ionic coordination crosslinking, yielding improved mechanical properties and sustained release of Zn 2+ , Sr 2+ , and PTH. In vitro evaluations demonstrated that the hydrogel enhanced BMSC proliferation, osteogenic differentiation, and mineralization, promoted HUVEC migration, tube formation, and angiogenic marker expression, and simultaneously inhibited osteoclastogenesis and bacterial growth. Transcriptomic analysis and inhibitor experiments revealed a dual paracrine mechanism mediating bone–vascular coupling: BMSC-derived HIF-1α–VEGF signaling facilitated angiogenesis, while HUVEC-derived PI3K–Akt–BMP-2 signaling enhanced osteogenesis. In vivo, the PTH/SrZnP@ZnCu-GGP hydrogel significantly accelerated bone regeneration and neovascularization in an ovariectomized rat calvarial defect model, accompanied by upregulated expression of BMP-2, RUNX2, p-Akt, and CD31. Collectively, this injectable hydrogel system offers a robust and translationally feasible strategy for coordinated osteogenesis–angiogenesis coupling, osteoclast suppression, and antibacterial defense, thus holding strong potential for the regeneration of osteoporotic bone defects.

Poly(styrene-ran-cinnamic acid) (SCA) Zn-salt ionomers (SCA‒Zn) bearing increasing contents (0, 0.23, 0.55, 1.3, 3.0, and 5.5 mol%) of Zn2+ ions were successfully synthesized by solution neutralization of the SCA with Zn2+ ions at room temperature. As the ion content of the SCA‒Zn increased from 0 to 5.5 mol%, the size and the aggregation number of the ionic aggregates did not change significantly, because the increase in ion content led to a monotonic increase in the number density of ionic aggregates, while the number of ions participating in the aggregates to form ionic aggregates was essentially fixed. Furthermore, the Tg values of the SCA‒Zn increased slowly as the Zn2+ ion content increased, and the linear increase rate with Zn2+ ion content was ∼0.8 °C mol−1, which was quite different from the reported increase rate in the Tg values of the matrix phase with Na+ ion content of 3–6 °C mol−1. This appeared to be caused by the steric hindrance effect of the adjacent groups of –COO− ions in the SCA and the long-distance electrostatic attraction. In addition, the degree of ionization of the SCA‒Zn was too low to cause large changes in thermal stability.

Zn–Mg–Cu TPMS gradient scaffolds were fabricated by selective laser melting. • Mg 2 Zn 11 and Cu 5 Zn 8 phases contributed to enhanced mechanical properties. • Gradient architecture and PDA coating regulated degradation behavior. • The integrated design improved surface bioactivity and promoted osteogenic differentiation. Biodegradable Zn-based scaffolds have attracted increasing attention for bone repair owing to their moderate degradation rate and favorable biological properties; however, achieving coordinated regulation of mechanical integrity, degradation behavior, and osteogenic activity remains challenging. Zn–Mg–Cu triply periodic minimal surface (TPMS) gyroid scaffolds with a radial pore-size gradient were fabricated by selective laser melting (SLM) and subsequently subjected to NaOH alkali-thermal activation and polydopamine (PDA) coating. The incorporation of Mg and Cu significantly enhanced the mechanical properties of the Zn alloy through solid-solution and second-phase strengthening. Meanwhile, the TPMS gradient porous architecture improved stress distribution and provided spatially graded pathways for electrolyte transport, thereby influencing degradation behavior and ion release characteristics. NaOH alkali-thermal treatment markedly improved surface wettability, and the PDA@Zn alloy scaffolds retained a hydrophilic interface; the complete surface treatment mitigated rapid ion release during the early stage of degradation. The scaffolds exhibited favorable compressive strength, controllable degradation behavior, and enhanced cytocompatibility. ICP-MS measurements revealed distinct Zn 2 + , Mg 2+ , and Cu 2+ release profiles, while the in vitro assays demonstrated favorable cell proliferation, osteogenic differentiation, and extracellular matrix mineralization. These biological responses may be associated with the combined effects of the released ions. Overall, the fabricated scaffolds exhibited favorable mechanical properties and controlled degradation behavior, while the complete surface treatment was associated with improved cytocompatibility and osteogenic activity.

Entropy engineering stabilizes V O frameworks via multi-cation co-doping. • DFT results show reduced Zn 2+ diffusion barriers through electronic tuning. • HE-VO cathodes achieve an ultra-low decay rate of 0.0034% per cycle. • High-mass-loading pouch cells demonstrate the practical scalability of HE-VO. Aqueous zinc-ion batteries (AZIBs) have emerged as promising candidates for safe and cost-effective energy storage. However, their practical deployment is constrained by sluggish Zn 2+ diffusion and structural degradation of cathode materials during cycling. Here, report an entropy-driven lattice reprogramming strategy that regulates layered vanadium oxide through multi-ion incorporation, enabling the construction of a high-entropy vanadium oxide (HE-VO) cathode. Beyond simple compositional modification, the introduced configurational entropy regulates the local coordination environment, simultaneously enhancing structural stability and Zn 2+ transport kinetics. As a result, HE-VO exhibits highly reversible Zn 2+ storage and outstanding electrochemical durability, delivering 300 mAh g −1 at 1 A g −1 and an ultralow capacity decay rate of only 0.0034% per cycle over 5000 cycles at 10 A g −1 . Moreover, a Zn||HE-VO pouch cell with a high-mass loading (∼8 mg cm −2 ) attains a specific capacity of 162 mAh g −1 at 2 A g −1 , highlighting the practical scalability of this strategy. This work provides a viable pathway toward the development of durable and high-rate electrode materials for advanced AZIBs. A HE-VO nanoribbon was synthesized through an entropy engineering strategy, which reprograms the V O lattice to enhance electronic structure, stabilize coordination, and facilitate ion diffusion via entropy-driven lattice expansion and charge redistribution. The tailored cathode consequently delivers exceptional electrochemical performance, while a high-loading pouch cell further demonstrates its practical viability, establishing entropy engineering as an effective strategy for achieving concurrently stable and fast-kinetic AZIBs.

Impaired infected wound healing is closely associated with mitochondrial dysfunction, and ferroptosis has emerged as a key mechanism connecting oxidative stress to mitochondrial damage. Baicalein holds potential for modulating this process, yet its application is constrained by poor bioavailability. Herein, a multifunctional nano-delivery system (Ba@Zn-MSN@CH) was rationally designed for infected wound treatment. Zinc-doped mesoporous silica nanoparticles (Zn-MSN) were synthesized to serve as a baicalein carrier. Carboxymethyl chitosan (CMCS) and dihydrocaffeic acid were covalently grafted onto the surface of the nanoparticles via silanization and amidation reactions, leading to the formation of a stable core-shell structure. The introduction of macromolecular coating was found to not only prolong drug release but also enhance antioxidant and antibacterial efficacy. What's more, Ba@Zn-MSN@CH effectively alleviated mitochondrial damage by inhibiting ferroptosis, thereby restoring cell proliferation, migration, and angiogenesis, and ultimately accelerating infected wound healing. Mechanistically, Ba@Zn-MSN@CH inhibited ferroptosis by inducing AMP-activated Protein Kinase α (AMPKα) phosphorylation in fibroblasts. AMPKα sustained the abundance of nuclear factor erythroid 2-related factor 2 (Nrf2), which subsequently suppressed lipid peroxidation and inhibited ferroptotic cell death through upregulation of downstream antioxidant factors. Collectively, these findings demonstrated that Ba@Zn-MSN@CH accelerated infected wound healing by inhibiting ferroptosis through activation of the AMPK/Nrf2 signaling pathway, highlighting the potential of baicalein-based nanotherapeutics as a promising strategy for infected wound management.
