A facile and eco-friendly strategy was developed to synthesize IL@MOF hybrid FR. • The optimized composite achieved a UL-94 V-0 rating with a LOI value of 27.1%. • The peak heat release rate and total smoke production were reduced by −76.1% and −83.1%. • The reaction to fire and its underlying mechanisms were systematically characterized. The deployment of thermoplastic polyurethane (TPU) in high-safety applications is critically hindered by its inherent flammability and the emission of toxic smoke during combustion. To address these limitations, this study proposes a new strategy driven by structural engineering and spatial confinement. Specifically, a zeolitic imidazolate framework-8 (ZIF-8) precursor was selectively etched using an eco-friendly tannic acid to engineer a mesoporous host architecture (TZIF-8). By encapsulating a bespoke phosphorus-containing ionic liquid (PMDP) within these tailored cavities, a highly efficient inorganic-organic hybrid (PM@TZ) was synthesized. It was subsequently compounded with piperazine pyrophosphate (PAPP) to construct a synergistic fire-protection network within the TPU matrix. The optimized composite (incorporating 6.5 wt% PAPP and 1.5 wt% PM@TZ) demonstrated excellent flame retardancy, achieving a UL-94 V -0 rating alongside a limiting oxygen index (LOI) of 27.1%. Forced-flaming evaluations confirmed dramatic reductions in the peak heat release rate (−76.1%), total heat release (−62.1%), and total smoke production (−83.1%) relative to the TPU. Mechanistic investigations across the volatile and condensed phases elucidated a robust synergic reaction to fire. The liberation of active phosphorus radicals facilitates profound gas-phase flame quenching, whereas the confined ionic liquid and MOF-derived catalytic zinc nodes cooperatively accelerate the formation of a highly graphitized, heteroatom-doped (P/Zn) char barrier. In summary, this study provides a versatile structural engineering route for resolving the interfacial incompatibilities of ionic liquids, paving the way for next-generation, high-performance, fire-safe elastomers.

Glutamate, the main excitatory neurotransmitter, exhibits release imbalance associated with epilepsy, Down syndrome, and other disorders. However, limited human tissue, interspecies differences, and inadequate in situ detection hinder mechanistic studies and interventions for glutamatergic dysfunction. Here, we constructed an integrated glutamatergic neuron-MNP@ZIF-8/ENZ platform that combines hiPSC-based directional differentiation of glutamatergic neurons on the enzyme-modified sensing surface with in situ neurotransmitter detection. Owing to the high porosity and electrical conductivity of the MNP@ZIF-8 nanocomposite, the platform exhibited a linear range of 1–50 μM (R 2 = 0.999), a detection limit of 0.76 μM, and high selectivity against common interferents such as DA, 5-HT, and Glc. After seven days of cell culture, the sensor response current retention rate is approximately 90.1%. Notably, the integrated platform was applied to Down syndrome (DS) research, revealing that depolarization-evoked glutamate release from DS patient iPSC-derived glutamatergic neurons was only approximately 28% of that from normal controls, providing direct quantitative evidence of excitatory transmitter secretion deficit in DS. This integrated sensing disease modeling platform provides a personalized, reproducible, and scalable analytical tool for disease pathogenesis research and drug screening, representing a promising technological platform.

Microwave synthesis enables atomic Fe dispersion in ZIF-8 - derived carbon. • Fe-doped carbon boosts low-concentration Li + adsorption via CDI. • Fe doping tunes porous structure and active sites. • Li + adsorption on Fe-N 4 is clarified by characterization and DFT. Lithium ions are widely present in various water resources, but their extraction has long been constrained by low lithium concentration in various water resources, necessitating the development of efficient extraction technologies. Capacitive deionization (CDI) is an emerging, energy-efficient technology for lithium recovery, yet its efficacy is largely constrained by the limited adsorption capacity of existing electrode materials. Herein, we developed a facile method to fabricate Fe N co-doped porous carbon materials (Fe-NC-M) derived from Zeolitic Imidazolate Framework-8 (ZIF-8) via a microwave-aided pyrolysis route. Microwave-assisted pyrolysis, leveraging rapid volumetric heating and selective energy absorption to achieve uniform Fe N 4 dispersion and construct a hierarchically porous carbon skeleton, effectively suppressing metal agglomeration. By modulating the Fe doping content, the electronic structure and surface chemistry of the carbon skeleton are refined, resulting in a remarkable enhancement in Li + adsorption. The optimized Fe-NC-M-150 electrode demonstrates an appreciable adsorption capacity for lithium ions, measuring 17.34 mg/g, surpassing most reported carbon-based CDI materials. Moreover, the electrode exhibits stable cyclic performance with 84.4% capacity retention after 20 adsorption-desorption cycles. A combination of physicochemical characterization, electrochemical analysis, and Density Functional Theory (DFT) calculations reveals that the Fe N 4 sites improve conductivity and ion diffusion kinetics, and provide strong coordination sites for Li + adsorption. This work provides a feasible strategy for designing high-performance CDI electrode materials toward efficient lithium resource recovery from low-concentration lithium resources.

A robust photothermal superhydrophobic coating was prepared via in-situ growth of ZIF-8. • Exceptional anti-icing shows 3.95 times freezing delay and 68.05% lower ice adhesion. • High photothermal efficiency of 76.56% enables rapid active ice melting and shedding. • Chemical bonding ensures durable performance after severe abrasion. In low-temperature and high-humidity environments, the accumulation of surface ice layers poses a serious safety threat to fields such as aerospace, power transmission, and transportation. However, traditional superhydrophobic coatings commonly suffer from poor mechanical robustness and functional failure under complex mechanical service conditions. In this work, Metal–organic frameworks (ZIF-8) were successfully grown in-situ on carboxylated multi-walled carbon nanotubes (MWCNTs-COOH), constructing a novel photothermal superhydrophobic composite coating with a multilevel micro-nanostructure. With the synergistic effect of an E51/PDMS resin matrix and subsequent modification by a low-surface-energy fluorosilane (PFTS), the coating achieves excellent superhydrophobicity and outstanding mechanical robustness. Anti-/de-icing tests demonstrate that at −20 ℃, the icing time is delayed by 3.95 times and the ice adhesion strength is reduced to 123.66 kPa. Benefiting from a high light absorption of 97.81% and a photothermal conversion efficiency of 76.56%, the coating enables rapid active melting of accumulated ice under simulated illumination. This integrated strategy—combining tough interfacial design, long-term passive anti-icing, and efficient active de-icing—provides an effective and stable solution for long-lasting ice protection of infrastructure.

To meet the diversity of usage scenarios, it is often difficult to simultaneously achieve superior mechanical properties, antistatic properties, wave-transparent properties, and thermal stability in blended systems. In this study, on a “soft-rigid” interfacial concept, a multi-interface was constructed between low-temperature carbonized carbon fiber (CF) and silicone resin (SR) by grafting a “soft” polydopamine/polyethyleneimine layer and growing “rigid” ZIF-8 particles on the CF surface. The improved mechanical meshing and interfacial polarization of the “soft-rigid” interface enhanced the mechanical properties and thermal stability of CF/SR composites. Notably, the tensile strength and elongation at break of ZCF-3/SR were 36.54% and 40.43% higher, respectively, than those of UCF/SR with unmodified CFs. After being held at 350 °C for a duration of 3 h, the weight loss of ZCF-3/SR was 17.47% lower than the corresponding value of UCF/SR. Subsequently, the electrical analysis showed that the surface resistance of ZCF-3/SR was more stable than that of UCF/SR after heating and maintained the wave-transparent properties (ε<3.3, tan δ <0.2). The electromagnetic wave analysis of ZCF-3 alone at a higher filler content of 60 wt% showed that ZCF-3 achieved an effective absorption bandwidth of 5.9 GHz and a maximum reflection loss of −53.6 dB, which demonstrates the tunability of electromagnetic properties by varying fiber content and offers a broad design window of the composites. It has promising applications in lightweight and flexible aerospace electronics. Download: Download high-res image (265KB) Download: Download full-size image

Postharvest apple ring rot caused by Botryosphaeria dothidea remains difficult to control due to the poor aqueous compatibility and rapid volatilization of volatile essential oils. We engineered a chitosan (CS) film embedding Ligusticum jeholense essential oil within zeolitic imidazolate framework-8 (LEO@ZIF-8) to achieve sustained antifungal release. TEM/SEM, FT-IR, XRD, and XPS confirmed high LEO loading (65.5%) and encapsulation efficiency. LEO@ZIF-8 demonstrated pH-responsive release, with 82.6% at pH 5.0. In vitro, LEO@ZIF-8 inhibited B. dothidea more effectively than free LEO (64.6% vs. 50.6% at 62.5 nL/mL). On detached apples, LEO@ZIF-8/CS film improved hydrophobicity, enhanced microstructural homogeneity, and delayed lesion formation. It reduced weight and firmness loss, retained soluble solids, and decreased oxidative stress markers (DPPH, SOD, MDA). ZIF-8 stabilized LEO and enabled controlled release, while CS provided antimicrobial support, demonstrating LEO@ZIF-8/CS as an effective active-packaging solution for long-term fruit preservation, offering a sustainable approach to postharvest disease control.

Polyurethane (PU) sponges are promising for oil-water separation, but their high flammability poses serious safety risks. To address this challenge, a multifunctional composite sponge was prepared by decorating a PU scaffold with a synergistic coating of polydimethylsiloxane (PDMS), NiCo-layered double hydroxide (LDH), and ZIF-8. This NiCo-LDH/ZIF-8@PDMS@PU composite sponge integrates superhydrophobicity, high oil-adsorption capacity, and intrinsic flame retardancy. The composite sponge exhibits a water contact angle of 153.4° and achieves self-extinguishing behavior, increasing the burning time from 5 s (pristine PU) to 16 s while eliminating melt dripping and reducing toxic fume emission. It shows high saturation adsorption capacity (26.6-82.9 g/g) for various oils and organics, and separation efficiency exceeding 99%, which remains above 98.5% after 20 adsorption-extrusion cycles. Furthermore, the composite sponge maintains its superhydrophobicity and separation performance after exposure to extreme pH, saline, and mechanical agitation conditions, demonstrating excellent environmental stability. This work provides a durable and safe material solution for oil-spill remediation, highlighting the great potential of multi-component synergistic design in developing advanced separation materials.

ZIF-8 as multi-dentate crosslinking hub converts weak CS/γ-PGA complexes into robust dual-network hydrogel. • Ultra-large pores eliminate diffusion limitation (Da ≈ 0.001) with K m increase of only 2.2-fold. • HSP regression (R 2 = 0.76, p ≈ 0.0002) validates synergistic thermodynamic exclusion and size-sieving mechanism. • Immobilized α-Glu@PC/ZIF-8 enables ligand fishing of two α-glucosidase inhibitors via capture-wash-elute workflow. Herein, a composite hydrogel based on two natural macromolecules—chitosan (CS) and γ-poly(glutamic acid) (γ-PGA)—was developed, crosslinked by zeolitic imidazolate framework-8 (ZIF-8) nanoparticles, which serve as reactive crosslinking hubs to covalently connect the biopolymer chains for efficient immobilization of α-glucosidase (α-Glu). A carboxyl-terminated poly(ethylene glycol)–poly(glutamic acid) copolymer was first synthesized and its activated carboxyl groups underwent amidation with amino groups of CS to rapidly form a three-dimensional PC/ZIF-8 hydrogel. The effects of ZIF-8 content and CS concentration on micro-morphology, swelling behavior, and rheological properties were systematically investigated. ZIF-8-mediated crosslinking was essential for gel formation, enabling effective modulation of network density and pore architecture. The optimized hydrogel showed no inhibitory effect on α-Glu. Immobilized α-Glu@PC/ZIF-8 exhibited enhanced pH stability (retaining 53% and 70% activity at pH 4.0 and 9.0), outstanding storage stability (>90% after 4 weeks), excellent organic solvent tolerance (>90% in most solvents), and good reusability (near 100% activity over 6 cycles). Mass transfer studies confirmed that the designed crosslinking density provided efficient substrate/product diffusion channels, minimizing product inhibition. Hansen solubility parameter analysis revealed a synergistic “thermodynamic exclusion + size-sieving” mechanism for solvent tolerance. Coupled with HPLC, the immobilized enzyme successfully identified two α-glucosidase inhibitors—batatasin I and 2,4-dimethoxy-6,7-dihydroxyphenanthrene—from Dioscorea opposita Thunb. peel. This work demonstrates that rational chemical modification of natural macromolecular networks via MOF crosslinkers provides an effective strategy for constructing high-performance enzyme immobilization platforms.

The mortality rate of primary liver malignant tumors is very high. Curcumin (Cur) is one of the most commonly used drugs for the treatment of liver cancer. However, due to its low bioavailability, nano-drug delivery systems are rapidly developing. Zeolitic imidazolate framework-8 (ZIF-8), is pH-sensitive and biodegradable in acidic environments, providing a very suitable platform for drug delivery. Here, the anti-tumor properties of Cur and the anti-inflammatory properties of gold nanoparticles (Au NPs) were integrated and encapsulated in ZIF-8 material to prepare a composite drug delivery system (Cur/Au@ZIF-8). The prepared materials were characterized by scanning electron microscopy and elemental analysis, transmission electron microscopy, and powder X-ray diffraction. The drug loading efficiency of Cur in this delivery system reached 47.16 %. The drug release curve showed that the release rate of Cur/Au@ZIF-8 was faster at pH 5.5, with a release rate of 72.34 %. Ultrasound-guided in situ liver cancer models were constructed in SD rats to investigate the in vivo anti-tumor effects of Cur/Au@ZIF-8 and its impact on the metabolomics of tumor-bearing rats before and after treatment. In vivo results indicated that Cur/Au@ZIF-8 showed better anti-tumor effects, with a tumor inhibition rate of 46.81 %. After treatment, 26 key differential metabolites (p < 0.05) were identified from expression patterns and metabolic pathways, which were mainly related to fatty acid metabolism. This treatment strategy provides a reference for future cancer treatment and mechanism exploration.

Polylactic acid (PLA) is a promising renewable polymer material known for its excellent biodegradability and good mechanical properties. However, its easy flammability and slow natural degradation limit its further applications. In this work, we designed a multi-layer core-shell flame retardant (ZIF-8@CH@APP) with interfacial characteristics through organic-inorganic hybrid technology. The interfacial functionalization of inorganic flame retardant ammonium polyphosphate (APP) was carried out with bio-based chitosan (CH), and the three-dimensional network was constructed by in-situ growth of metal-organic framework (ZIF-8). With 7 wt% addition of ZIF-8@CH@APP, the PLA composite exhibited excellent flame retarded properties. It showed V -0 vertical burning (UL-94) grade, and reduced total smoke produce (TSP) (0.2 m 2 ). Additionally, the PLA/7 % ZIF-8@CH@APP composite exhibited higher degradation rate at mild condition. Additionally, the final degradation product of ZIF-8@CH@APP was confirmed to be DL-lactic acid. The design not only improves the interface compatibility between inorganic phase and polymer matrix, but also realizes the double breakthrough of flame retardant and catalytic degradation function through physical-chemical synergism, providing an innovative solution for the recycle of PLA material.

3D-printed titanium implants are extensively utilized in bone reconstruction. However, their bioinertness and lack of antibacterial activity increase risks of aseptic loosening and implant-associated infection—the primary causes of implant failure. To address these limitations, we developed a dual-functional 3D-printed porous titanium–hydrogel composite scaffold to enhance the osteogenic and antibacterial capacities of titanium. This composite scaffold was fabricated by integrating quaternized chitosan (QCS)/aldehyde-terminated Pluronic F127 (PF127-CHO) hydrogel loaded with magnesium ions (Mg 2+ ) and zeolitic imidazolate framework-8 (ZIF-8) into polydopamine-coated 3D-printed porous titanium scaffold. The composite scaffold exhibited sustained and controlled release of Mg 2+ and ZIF-8 with enhanced binding strength at titanium–hydrogel interface. In vitro experiments demonstrated that the composite scaffold possessed favorable biocompatibility, promoted the adhesion and proliferation of MC3T3-E1 cells, and facilitated their osteogenic differentiation through synergistic effect of Mg 2+ and ZIF-8. Furthermore, it also inhibited bacterial growth via synergistic action of QCS/PF127-CHO hydrogel and ZIF-8. In vivo experiments confirmed enhanced bone ingrowth into the composite scaffold and its effective antibacterial activity. In summary, this composite scaffold provides a promising strategy to simultaneously improve the osteogenic and antibacterial capacities of titanium implants.

The anodic precious metal catalyst of direct methanol fuel cell (DMFC) is poisoned due to CO adsorption, which makes the methanol oxidation reaction (MOR) kinetics tardily. In this study, a series of hierarchical core–shell structure catalysts PdZn/ZDC@SiO 2 were synthesized by loading PdZn nanoparticles (NPs) on ZIF-8 derived porous carbon (ZDC) and protecting by the mesoporous silica (SiO 2 ) are reported. A hierarchical core–shell structure informed in PdZn/ZDC@SiO 2(20) caused by mesoporous silica shell leads to well-dispersed and uniform of PdZn NPs (10 nm). Compared with commercial palladium carbon (Pd/C), the optimized catalyst PdZn/ZDC@SiO 2(20) has higher current density (765.2 mA/mg) and stronger CO toxicity tolerance (I f /I b = 3.30). And the onset potential and the peak potential of PdZn/ZDC@SiO 2(20) (−0.294 V, −0.203 V) are more negative in CO stripping experiment. Silica is an inorganic oxide that can provide oxygen-containing species to the adjoining precious metal sites and promote CO oxidation. In addition, PdZn NPs can accelerated electron transport and then improve methanol oxidation performance due to the changing electronic structure of Pd and the modifying the surface adsorption of the catalyst. PdZn/ZDC@SiO 2(20) is a potential substitute material for noble metal catalyst that can be used for direct methanol fuel cells.
