CO2 + O2 neutral leaching represents a promising sustainable method for uranium extraction; however, its practical effectiveness is frequently limited by the slow kinetics of CO2 hydration, which hinders the formation of bicarbonate ions essential for the complexation and dissolution of uranium. To overcome this kinetic limitation, a novel magnetic zinc-coordinated carbonic anhydrase-mimicking nanozyme (Fe3O4@ZnAC) was successfully developed via a facile one-pot sol–gel coating strategy. Comprehensive characterization confirmed that the nanozyme exhibits a distinctive core–shell heterostructure, consisting of a superparamagnetic Fe3O4 core enabling facile magnetic recovery and a zinc-rich organosilicate shell providing abundant, accessible Zn–N/O catalytic sites analogous to natural carbonic anhydrase. Enzymatic studies revealed that Fe3O4@ZnAC possesses outstanding carbonic anhydrase-mimicking catalytic performance, robust operational stability, and excellent recyclability, highlighting its potential for sustainable industrial applications. When integrated into a dual-reactor uranium leaching system, Fe3O4@ZnAC substantially increased bicarbonate ion production by approximately 47% compared to the uncatalyzed scenario. This catalytic improvement resulted in a uranium extraction efficiency of 45.79%, significantly higher than the 36.36% observed in control experiments. This study provides valuable insights into the rational design and practical application of biomimetic nanozymes, proposing an effective strategy for integrating efficient resource recovery with sustainability and global carbon neutrality goals.

The coordinated metal single-atoms (MSA) can significantly enhance the electromagnetic wave (EMW) absorption properties of materials through adjusting local electron structure and polarization relaxation. The symmetric electronic environments for EMW absorption have been extensively studied, but the asymmetric electron dispersion from an atomic-scale perspective is blurring puzzle. In this work, the amorphous polymer-derived SiZnCN ceramics with porous “Cheese” structure were prepared by regulating Zn coordination and pyrolysis temperature. The SiZnCN (15 wt% ZnAc doping) ceramics pyrolyzed at 1400 °C exhibits an effective absorption bandwidth (EAB) of 4.96 GHz at an ultrathin thickness of 1.28 mm. This SiZnCN ceramics after oxidized at 500 °C still possesses excellent high-temperature EMW absorption performance. Benefiting from the porous structure and coordinated single Zn atoms, the asymmetric electronic environment in amorphous SiZnCN ceramics is established, promoting electron/dipole and interfacial polarization. This work proposes an effective strategy to optimize electromagnetic wave absorption for high temperature by coordinating asymmetric electronic environments in disordered structures.

Co-Fe spinel oxides are attractive alternatives to noble metal-based electrocatalysts for water splitting due to their abundant reserves, unique electrochemical redox characteristics and inherent stability. However, their alkaline HER performance under high-current conditions remains limited by inefficient water adsorption/dissociation and suboptimal hydrogen adsorption balance. Herein, a 600-cm 2 amorphous Ce-doped Co 2 FeO 4 cathode with Zn vacancies (Ce, Zn v -Co 2 FeO 4 ) were synthesized by electrodeposition and alkaline etching method. It exhibits exceptional alkaline HER performance with low overpotentials of 47.5 and 247.5 mV at 10 and 1000 mA cm −2 , meanwhile maintaining high stability over 500 h at 1000 mA cm −2 with a potential retention rate of 96.5%. The resulting water electrolyzer with Ce, Zn v -Co 2 FeO 4 as cathode only needs a cell voltage of 1.90 V at 1000 mA cm −2 for overall water splitting. In-situ electrochemical tests and density functional theory (DFT) calculations demonstrate that the synergistic effect of Ce doping and Zn vacancies in Co 2 FeO 4 leads to a 50% reduction in bandgap, thereby enhancing conductivity. It also facilitates spontaneous water adsorption and dissociation, reduces the energy barrier by 46%, and optimizes the balance of hydrogen adsorption/desorption, thereby ultimately enhancing HER activity. This study presents a potential strategy to address the performance limitations of spinel-based HER catalysts.

Design of the photosensitive electrode material provides an effective strategy to improve the capacity and stability of supercapacitors. In this study, the photothermal-driven cobalt–zinc-doped Ni(OH)2/g-C3N4@NF nanoflower electrode materials were prepared base on the in situ chemical etching strategy. The electrochemical performance indicated that the optimized CZNC2.18 (cobalt–zinc codoped β-Ni(OH)2@g-C3N4) electrode material with exceptional stability (103.74% capacitance retention after 5000 cycles at 20 mA/cm2) exhibited an ultrahigh capacitance of 19.10 F/cm2 at a current density of 10 mA/cm2 under illumination, compared to 12.8 F/cm2 under dark conditions, achieving a light gain of 149%. The assembled asymmetric photothermal-assisted supercapacitor device delivers energy densities of 3.55 mWh/cm2 (1.23 mWh/cm2) at corresponding power densities of 8.39 mW/cm2 (37.03 mW/cm2) under illumination, surpassing performance metrics observed under dark conditions. The synergistic effects of photogenerated carriers (holes oxidizing Ni(OH)2 to NiOOH and electrons enhancing conductivity), Zn/Co codoping-induced conductivity improvement, and photothermal-assisted ion transport collectively enable CZNC2.18 exceptional photoelectrochemical performance, establishing a paradigm for light-responsive energy storage material design.

Aqueous zinc–iodine batteries (AZIBs) show great promise for sustainable energy storage due to inherent safety, cost-effectiveness, and environmental compatibility. However, their practical implementation is critically hindered by polyiodide shuttling, particularly under low current densities, leading to rapid capacity decay. Herein, poly(diallyldimethylammonium chloride) (PDDA) is employed as a functional binder to construct carbon nanotubes (CNTs)/PDDA composite cathodes. Unlike conventional carboxymethyl cellulose (CMC) based CNTs/CMC cathodes with compromised Coulombic efficiency (49.6% at 0.1 A g −1 ), the CNTs/PDDA architecture effectively anchors polyiodides to suppress the shuttle effect and self-discharge through robust electrostatic interaction between quaternary ammonium groups and polyiodide ions. The optimized AZIBs exhibit high Coulombic efficiency (>98.2% at 0.1 A g −1 ), large specific capacity (231.1 mAh g −1 at 0.1 A g −1 ), high durable cycling stability (45 000 cycles at 3.0 A g −1 ), and sustained open-circuit voltage (1.326 V after 12-h rest). Mechanism studies reveal the dual functionalities of the PDDA binder in mitigating polyiodide shuttling and zinc anode corrosion. The PDDA system exhibits reduced Gibbs free energy (ΔG) and narrowed redox potential gaps, which effectively immobilize polyiodide species and promote the complete conversion of I − → I 3 − → I 2 . This work highlights the great potential of PDDA as a functional binder for high-performance AZIBs.

Achieving a high depth of discharge (DOD) in dendrite-free Zn anodes is essential for enhancing the energy density and cycling lifespan of zinc-ion batteries (ZIBs). However, conventional three-dimensional (3D) anodes featuring thick and disordered pore structures suffer from gradient and tortuous ion diffusion pathways, leading to mismatched electron/ionic transfer kinetics, which limit their DODs to usually lower than 40%. Herein, a low-tortuosity, N-doped 3D Zn anode is deftly crafted by 3D printing. The vertically aligned pore architecture significantly reduces electrode tortuosity, enabling rapid ion transport with shortened migration pathways. Meanwhile, the N-doped zincophilic surface substantially reduces the deposition energy barrier for uniform and compact Zn deposition even under high DODs. The resulting symmetrical cells exhibit dendrite-free cycling for 720 h at 1 mA cm −2 and 1 mAh cm −2 while sustaining stable plating/stripping processes at a high DOD of 61.7%. This work offers fundamental insights into the anode design philosophy for long-lasting and energy-dense ZIBs.

Despite recent advancements in lipid nanoparticles (LNPs)-based messenger RNA (mRNA) delivery, significant challenges persist in the structural optimization and functional modulation of their components for cancer immunotherapy, particularly regarding inadequate organ-specific targeting, and insufficient immune activation. Notably, metal ions have demonstrated emerging immunomodulatory potential, yet their coordinated self-assembly within LNPs as adjuvants to enhance the immunotherapeutic efficacy remains largely unexplored. To address these limitations, we combine newly designed imidazole-based LNPs with functional metal ions (Zn 2+ ) to develop novel Zn-coordinated LNP-based mRNA vaccines. A total of 48 imidazole-based ionizable lipids were designed and synthesized, among which C2–13 LNPs emerged as the top-performing formulation in terms of transfection efficiency. By innovatively incorporating Zn 2+ into C2–13 LNPs via coordination interaction, we further developed the novel metal-coordinated mRNA delivery systems, referred to as Zn-C2–13 LNPs. Compared to their non-metal counterparts, Zn-C2–13 LNPs exhibited markedly improved transfection efficiency and antigen presentation in vitro . Impressively, the synergistic effect of the optimized LNP formulation and Zn 2+ in the Zn-C2–13/mOVA systems (Zn-C2–13 LNPs loading ovalbumin mRNA) resulted in superior spleen-selective expression and immune response, significantly boosting the efficacy of cancer immunotherapy in the B16F10 ovalbumin-expressing (B16F10-OVA) melanoma tumor model. Collectively, this novel metal-coordinated LNPs improve specific organ targeting and immune responses, presenting a promising strategy to advance mRNA vaccine-based cancer immunotherapy.

Rational design and synthesis of electrocatalysts that efficiently catalyze oxygen reduction reaction (ORR) is critical to the development of fuel cells and Zn-air battery (ZAB). However, it remains the most significant obstacle due to the potential-dependent energy barrier for oxygen intermediates (OOH*, O* and OH*) adsorption/desorption on single atom active sites. Here we report a novel deprotonated 2-aminoterephthalic acid (H 2 BDC-NH 2 ) coordinated compound precursor-mediated method for synthesizing dual-atomic-site electrocatalyst (FeNi-DSAs/NSs) that facilitate ORR kinetics. The experimental and theoretical calculation results verify that the Fe and Ni cooperative effect induces a distinct negative shift of the d-band center for Fe, thereby reducing the adsorption strength of oxygen intermediates on Fe sites. Additionally, the introduced Ni species decrease the energy barrier of the rate-determining step (RDS), thus accelerating catalytic ORR process. Consequently, FeNi-DSAs/NSs exhibits excellent ORR performance in 0.1 M KOH solution with a very large half-wave potential (E 1/2 ) of 0.92 V and a remarkable lifespan, maintaining stability for over 90 h. In aqueous Zn-air battery (A-ZAB), this electrocatalyst enables a high-power density (254 mW cm −2 ), and can maintain stable charge/discharge for more than 1600 h with negligible potential gap fluctuation. Notably, for quasi-solid-state Zn-air battery (QSS-ZAB) with FeNi-DSAs/NSs, it shows excellent cycle life for over 110 h and high energy conversion efficiency at 0.5, 1.0, and 2.0 mA cm −2 , respectively. This work not only provides a novel design strategy for excellent catalysts, but also highlights the potential application of non-precious metal electrocatalysts in renewable energy conversion and storage apparatuses.

Carbon-based substrates in Zn–MnO 2 flexible batteries have issues of low adhesion to MnO 2 , impacting cycle stability and capacity performance. A triple-synergistic strategy integrating C–O–Mn covalent bonding, wettability optimization, and hierarchical mesoporous engineering via cellulose nanofibers/carbon nanotube (CNF/CNT)-modified carbon cloth (CC) was proposed. This design achieves a “surface-locking” effect between the substrate and electrode materials, which was proven through theory and experiments. Density functional theory (DFT) simulations validate the “surface-locking” mechanism, where oxygen functionalities on CNF can form robust CO–Mn bonds with MnO 2 , inducing an increase in MnO 2 adsorption energy from −0.21 eV (pristine CC) to −1.36 eV, effectively suppressing Mn dissolution. Optimal wettability (contact angle: 97°) reduced Zn 2+ desolvation and water-induced side reactions. Hierarchical pore structures accelerated Zn 2+ diffusion. The optimized CC@CNF 1 /CNT 2 –MnO 2 cathode achieves 92% capacity retention after 2000 cycles at 1 A/g. This study highlights a surface engineering strategy that effectively addresses the individual challenges associated with interfacial adhesion, reaction kinetics, and ion transport. This strategy offers fundamental insights into electrode interface modification for the development of next-generation flexible energy storage systems.

A novel aqueous/aprotic electrolyte with low salt concentration (i.e., 0.5 m Zn(CF 3 SO 3 ) 2 +1 m LiTFSI) demonstrated an expanded electrochemical window, which can simultaneously stabilize Zn metal anode and increase the operation voltage of Zn-ion hybrid supercapacitors.
The coordination shell of the electrolyte induced by acetonitrile and LiTFSI can not only suppress the Zn corrosion and hydrogen evolution reaction but also promote the cathodic stability and ion migration, which is depicted by the density functional theory simulations together with experimental characterizations.
The Zn-ion hybrid supercapacitor based on the developed electrolyte can operate within 0–2.2 V in a wide temperature range with an ultra-long lifespan (> 120,000 cycles).

Wearable biomedical devices require materials that simultaneously integrate energy storage and sensing, function under extreme conditions, and enable battery self-diagnosis. To address this, we developed a novel ZnCl₂-loaded poly(acrylic acid)-based composite hydrogel (Zn-PAA-C) serving as both a flexible Zn-ion battery electrolyte and a high-performance strain sensor. Engineered with poly(acrylic acid) N-hydroxysuccinimide ester (PAA-NHS), gelatin, and ethylene glycol, Zn-PAA-C exhibits exceptional ionic conductivity, mechanical resilience, and freeze-resistance (down to -80 °C). As a strain sensor, it achieves a broad sensing range (0–180 % strain), reliable operation (1–7 Hz), and rapid response (57 ms). As a battery electrolyte, it uniquely incorporates self-diagnostic capability, enabling real-time monitoring of battery expansion and dendrite formation for enhanced safety and longevity, and supports stable operation over 12,000 charge-discharge cycles. Zn-PAA-C thus transcends traditional gel electrolyte limitations, establishing a new standard for multifunctional materials in wearable biomedical devices capable of robust, continuous health monitoring under extreme conditions.

The severe dendrite issue of the Zn anode greatly hinders the practical application of aqueous zinc-ion batteries, which demands a prompt solution. This work proposes an electrostripping strategy using sodium citrate (SC) solution as the electrolyte to fabricate a 3D honeycomb-like Zn (3DH-Zn) anode. Theoretical calculations and experimental results reveal that SC preferentially adsorbs on the Zn(100) and Zn(101) planes and exhibits a shielding effect, leading to the major dissolution of Zn atoms from the Zn(002) plane, thus obtaining a honeycomb-like structure. Notably, convinced by morphology characterization and finite element simulation results, Zn 2+ tends to deposit on the lateral sides of the hexagonal holes on the 3DH-Zn anode, resulting in a flat deposition morphology dominated by Zn(101)/Zn(100) planes, which significantly inhibits dendrite formation. As a result, the 3DH-Zn symmetric cell achieves an ultra-long lifespan of 2000 h at 5.0 mA cm −2 and 1.0 mAh cm −2 . Besides, the 3DH-Zn||VO 2 full cell works for 1000 cycles at 1.0 A g −1 with a residual capacity of 123.1 mAh g −1 . This work opens up a new horizon for applying electrostripping strategy in designing advanced Zn anode.
