High ion-selectivity and robust long-term stability are critical performance metrics for nanofiltration (NF) membranes targeting lithium extraction from high-salinity brines with impurities and high magnesium lithium ratios. Herein, a positive and negative heterostructure dual-layer NF membrane with sub-10 nanometer PA layer on 2D Zn-TCPP nanosheets through interfacial polymerization method coupled with vacuum assisted filtration was constructed. PA layer with positively charge on the top performed as the ‘shield’ that effectively retains Mg2+, while negatively charged Zn-TCPP coupled with uniform pores performed as the ‘accelerator’ to facilitate Li+ permeate. The addition of Zn-TCPP can increase the membrane free volume fraction and construct effective screening channels. An appropriate amount of Zn-TCPP nanosheets can construct PA layers as thin as 5 nm and lead to the best Li/Mg separation performance. (Water permeance of 6.79 L⋅m−2⋅h−1 bar−1 over 360 hours continuous operation when Mg/Li ratio is 50:1, and Li+/Mg2+ separation factor is 80.79). In the ternary metal ions solution tests (Li⁺, Mg²⁺, X⁺, where X = Na⁺ or K⁺ with doubled concentration), Li+/Mg2+ separation factor remains still above 40. The DFT simulations and molecular dynamics reveal The transmembrane energy barrier for Mg²⁺ significantly exceeds that for Li⁺ across the membrane. The adsorption heights of ions on Zn-TCPP in a stable state, the different ion perforation energy and ion diffusion rate furtherly explain the reason for the membrane with excellent separation performance.

Aqueous zinc metal batteries are noted for their cost-effectiveness, safety and environmental friendliness. However, the water-induced notorious issues such as continuous electrolyte decomposition and uneven Zn electrochemical deposition remarkably restrict the development of the long-life zinc metal batteries. In this study, zwitterionic sulfobetaine is introduced to copolymerize with acrylamide in zinc perchlorate (Zn(ClO 4 ) 2 ) solution. The designed gel framework with hydrophilic and charged groups can firmly anchor water molecules and construct ion migration channels to accelerate ion transport. The in situ generated hybrid interface, which is composed of the organic functionalized outer layer and inorganic Cl − containing inner layer, can synergically lower the mass transfer overpotential, reduce water-related side reactions and lead to uniform Zn deposition. Such a novel electrolyte configuration enables Zn//Zn cells with an ultra-long cycling life of over 3000 h and a low polarization potential (~ 0.03 V) and Zn//Cu cells with high Coulombic efficiency of 99.18% for 1000 cycles. Full cells matched with MnO 2 cathodes delivered laudable cycling stability and impressive shelving ability. Besides, the flexible quasi-solid-state batteries which are equipped with the anti-vandalism ability (such as cutting, hammering and soaking) can successfully power the LED simultaneously. Such a safe, processable and durable hydrogel promises significant application potential for long-life flexible electronic devices.

Zintl-phase thermoelectrics with CaAl 2 Si 2 -type structures exhibit desirable “phonon-glass electron-crystal” behavior. However, the development of environmentally friendly p-type counterparts remains challenging. While n-type Mg 3 Sb 2 -based compounds have achieved high figures of merit ( zT > 2.0), their integration with non-Zintl systems is hindered by thermal and chemical mismatches. Moreover, many existing p-type Zintl compounds rely on toxic (Cd, Pb) or scarce (Yb, Ge) elements, restricting their scalability and sustainability. Here, we report a scalable, rare-earth- and toxicity-free p-type Zintl compound, Ca 0.5 Mg 1.297 Ag 0.003 Zn 1.2 Sb 2 , developed via targeted Mg-site substitution. First-principles calculations reveal that Ca substitution at Mg1 sites induces beneficial electronic structure modifications, including bandgap widening, valence band sharpening, and an indirect-to-direct bandgap transition, collectively enhancing carrier mobility (50 cm 2 ·V -1 ·s -1 ) and strengthening carrier-phonon scattering at elevated temperature. Simultaneously, trace Ag doping at Mg2 sites precisely tunes the carrier concentration by nearly one order of magnitude, achieving improved electrical conductivity while maintaining ultralow thermal conductivity. As a result, the optimized compound achieves a peak zT of 0.81 at 773 K and an average zT of 0.50 over 300–773 K. These results demonstrate a chemically stable, sustainable, and high-performing Zintl platform, offering a promising strategy for advancing eco-friendly thermoelectric technologies.

The synergistic “anchor-capture” mechanism of polar groups on Zn stripping/plating process is firstly proposed.
The amino group firmly anchors on Zn surface and the carboxyl group strongly captures Zn 2+ , constructing a robust anode–electrolyte interface and inducing uniform Zn deposition.
The ultra-stable cycle lifespan of Zn–Zn symmetric cell (over 2800 h) and high utilization rate of Zn anode (the depth of discharge up to 68% for 200 h) are achieved under the proposal of synergistic “anchor-capture.”

Flow batteries are promising for renewable energy storage due to their safety and scalability. Zinc/bromine flow batteries (Zn/Br) are popular due to their high energy densities and inexpensive electrolytes. However, they have a poor service life and lead to environmental harm as a result of the generated corrosive and volatile Br 2 . Here we introduce a Br 2 scavenger to the catholyte, reducing the Br 2 concentration to an acceptable level (~7 mM). The scavenger, sodium sulfamate (SANa), reacts rapidly with Br 2 to form a mild product, N -bromo sodium sulfamate (Br-SANa; Br + ). Additionally, the two-electron transfer reaction of Br-SANa/Br − (Br + /Br − ) increases the energy density. We have developed a Zn/Br flow battery, paired with a Zn anode, that outperforms traditional Zn/Br flow batteries in energy density (152 Wh l −1 versus 90 Wh l −1 ) and cycle life (>600 versus 30 cycles), using a sulfonated polyetheretherketone membrane. We assembled a 5-kW stack that operated stably for over 700 cycles (~1,400 h). Using this reaction, we have built a large-scale battery system.

Nanotechnology has provided a novel approach for the preparation of a safe and highly effective pesticide formulation. Thiazole-Zn, a widely used bactericide, was successfully prepared at nanoscale by an innovative approach of final synthesis process control. Its plausible formation mechanism based on restricted particle aggregation in a nanoreactor was elucidated. Then in order to assess the application performance of thiazole-Zn nanoparticle, the nanoformulation (NPF) was conveniently formulated. Interestingly, the physicochemical properties of NPF showed better than that of the commercial pesticide formulation (CPF) in dispersibility, wettability, spreadability, and stability. At the same time, the in vitro bioassay showed that the minimum inhibitory concentrations (MICs) of NPF against Xanthomonas oryzae pv Oryzae (XOO), Xanthomonas oryzae pv Oryzicola (XOC), Erwinia carotovora subsp. Carotovora (Jones) Holland (ECC), and Erwinia chrysanthemi pv Zeae (ECZ) were 46.88, 93.75, 93.75, and 375.00 mg/L, respectively, whereas those of CPF were 93.75, 375.00, 375.00, and 875.00 mg/L, respectively. Therefore, NPF exhibited stronger antibacterial activity against the above-mentioned pathogens. Moreover, NPF was more effective to bacterial blight of rice than CPF in field trial. As a conclusion, nanotechnology for pesticides by synthesis process control will have a potential in improving the utilization efficiency and relieving the corresponding environmental pollution.

The side reaction and dendrite of a zinc anode in an aqueous electrolyte represent a huge obstacle for the development of rechargeable aqueous Zn batteries. An electrolyte with confined water is recognized to fundamentally stabilize the zinc anode. This work proposes acetamide/zinc perchlorate hexahydrate (AA/ZPH) ionic liquid (IL)-polyacrylamide (PAM) polymer electrolytes, here defined as IL-PAM. The novel Zn2+-conducting IL is able to accommodate trace water and can achieve both high conductivity (15.02 mS cm–1) and alleviation of side reactions (>90% reduction). Cross-linked PAM acts as the three-dimensional framework to suppress dendrites and obtain flexibility. As a result, the Zn anode with IL-PAM can cycle stably over 2000 h with a record highest cumulative capacity of 3000 mAh cm–2 and well-preserved morphology. Based on IL-PAM, the flexible LFP|Zn hybrid batteries can be successfully assembled and operate normally in series and parallel conditions. Moreover, the low volatility of IL and binding forces exerted by the PAM network endues IL-PAM with an anti-dehydration property. In a 50 °C unsealed environment, the weight loss of IL-PAM is about two-fifths of PAM hydrogel and an aqueous electrolyte, and the corresponding hybrid battery with IL-PAM can also prolong a 4 times longer lifespan.

Red-emissive Cu nanoclusters were synthesized via a green room-temperature strategy using glutathione and ascorbic acid. • Zn 0.4 Mn 0.6 Fe 2 O 4 nanoparticles were selected as the magnetic component owing to their superior magnetic properties over conventional Fe 3 O 4 . • Cu nanocluster-decorated Zn 0.4 Mn 0.6 Fe 2 O 4 nanocomposites were successfully fabricated through a simple assembly process. • The optimized nanocomposite integrated bright red fluorescence with excellent T 2 -weighted magnetic resonance performance. • A green and low-cost strategy was developed for constructing multifunctional fluorescence/MR nanocomposites. Given the intrinsic limitations of single-modality imaging, integrating optical and magnetic functionalities into a single nanoplatform offers a promising strategy for multimodal imaging. Herein, Cu nanocluster-decorated Zn 0.4 Mn 0.6 Fe 2 O 4 nanocomposites (CuNCs-ZMF) were rationally fabricated for dual-modal fluorescence and magnetic resonance imaging. Glutathione-protected CuNCs were synthesized using ascorbic acid as a mild reductant, while superparamagnetic Zn 0.4 Mn 0.6 Fe 2 O 4 nanoparticles were synthesized via thermal decomposition and subsequently surface-functionalized with cetyltrimethylammonium bromide to improve aqueous dispersibility and facilitate assembly with CuNCs. The resulting CuNCs-ZMF exhibited red fluorescence centered at 660 nm with an absolute quantum yield of 5.89% and a transverse relaxivity ( r 2 ) of 160.52 mM −1 s −1 . T 2 -weighted MR imaging demonstrated Fe concentration-dependent negative contrast enhancement, while in vivo imaging revealed pronounced darkening of the liver region following intravenous administration. CCK-8 assays further demonstrated relatively favorable cytocompatibility at low-to-moderate concentrations. These results demonstrate the successful integration of fluorescence and magnetic resonance imaging capabilities and support the potential of CuNCs-ZMF for fluorescence/MRI dual-modal imaging applications.

The deactivation of Pt-based catalysts is the most critical problem in nonoxidative propane dehydrogenation reaction (PDH), usually manifested in carbon deposition and active site sintering. Zn, as another cheap metal with more abundant reserves than Sn, is also widely used as an assistant in Pt-based catalysts. However, both of them are easy to be reduced to metal valence state and lost in the reaction process. Herein, the enlarged quantities of Zn are applied in the bimetallic Pt-Zn catalyst preparation. As confirmed by the increased reduction temperature of oxidized Zn species, it effectively minimizes the influence of the active metal mobility caused by Zn loss. At the same time, the constructed bimetallic structure modulates the surface acidity of Zn species and presents benign propylene desorption ability, thus the formed highly dispersed Pt sites on the surface of Pt 1 Zn 1 alloy are well-matched with its high propylene selectivity (∼98.6%). In addition, the rich-Zn Pt 1 Zn 1 sites are beneficial for enhancing the capability of resisting-coke, thus retarding the deactivation of this catalyst.

Although cGAS-STING immunotherapy holds immense potential, its efficacy is severely compromised by pathway evasion. To overcome this, we engineered a core-shell bilayer nanobomb (M/ZIF/MnO 2 @DBCO) via a template-assisted approach, integrating MSC1094308 into ZIF-8 cores followed by MnO 2 shell deposition and DBCO functionalization. In a simulated tumor microenvironment, ZIF-8 loading accelerated Mn 2+ release from MnO 2 , increasing the cumulative release by nearly 30% within 8 h compared to pristine MnO 2 . Cellular assays demonstrated rapid bio-orthogonal targeting of azide-modified tumors, achieving lysosomal escape within 6 h postuptake. Subsequently, MnO 2 -mediated glutathione (GSH) depletion and hydroxyl radical (·OH) generation, combined with Zn 2+ induced mitochondrial oxidative stress, produced cytotoxic reactive oxygen species (ROS) that triggered immunogenic cell death. Furthermore, Mn 2+ , Zn 2+ , and dsDNA released from damaged mitochondria cooperatively activated the cGAS-STING pathway. Concurrently, MSC1094308 inhibited ESCRT-mediated negative regulation, as evidenced by a ∼0.2 decrease in the p-STING/VPS4B-RFP colocalization coefficient, confirming the blockade of cGAS-STING evasion. In vivo studies revealed that the nanoplatform profoundly stimulated antitumor immunity, increasing tumor-infiltrating cytotoxic T lymphocytes approximately 8-fold versus untreated controls after 21 days. This work establishes an integrated strategy harnessing Zn 2+ /Mn 2+ synergy, nanobomb reactivity, and ESCRT inhibition to circumvent cGAS-STING evasion, offering a promising paradigm for cancer immunotherapy.

Sub-micron Bi chemically anchors polyiodides via Bi-I bonds to suppress shuttling. • S-Bi acts as both an iodine host and an electroactive capacity contributor. • A cascade reaction involving I 0 /I − and Bi 3+ /Bi redox couples is realized. • The Zn–I₂ battery delivers 245 mAh g −1 and cycles 20,000 times with 77.7% retention. • A pouch cell achieves 5.26 mAh cm −2 under 22 mg cm −2 mass loading. Polyiodide shuttling is the primary obstacle to impede the practical application of aqueous zinc–iodine batteries (AZIBs). Although various host materials have been developed to suppress the shuttle effect, most of them are electrochemically inactive and inevitably reduce the overall energy density of the cathode. Herein, sub-micron bismuth (S-Bi) powder as a multifunctional redox-active iodophilic additive was introduced into the iodine electrode to simultaneously regulate iodine conversion chemistry and contribute additional electrochemical capacity. Experiment results showed that S-Bi powder with high electronic conductivity and mesopore structure can chemically anchor polyiodide by forming Bi-I bonds, which benefits suppressing polyiodide shuttling and enhancing reaction kinetics. More importantly, a cascade reaction process containing I 0 /I − and Bi 3+ /Bi redox couples is realized, significantly boosting battery capacity. In-situ XRD characterization revealed the conversion route of bismuth species (BiOI ↔ Bi 2 O 3 ↔ Bi) during the reaction, providing the direct evidence for the bismuth-involved cascade reaction mechanism. As a result, the assembled AZIBs based on S-Bi powder deliver a high discharge specific capacity of 245.19 mAh g −1 at 0.5 A g −1 and operate stably for 20,000 cycles at 3 A g −1 with a capacity retention of 77.7%. Encouragingly, the pouch battery achieves an areal capacity of 5.26 mAh cm −2 under a high active material mass loading of 22 mg cm −2 , demonstrating practical application potential. This work paves the way for designing materials with iodine affinity and redox activity to simultaneously suppress polyiodide shuttling and contribute extra capacity for AZIBs. Submicron mesoporous bismuth as a functional additive in I₂/KB cathode establishes a cascade reaction mechanism and inhibits polyiodide shuttling by forming Bi-I bonding, enabling 20,000-cycle stability.
