Hard carbon rich in closed pores is considered a highly promising anode candidate for advanced sodium-ion batteries (SIBs). Nevertheless, the precise regulation of closed pore structures is significantly impeded by the structural complexity of hard carbon. In this study, a hard carbon with tunable closed-pore architecture was constructed by using ZIF-8-derived porous carbon with uniform pore size (~0.8 nm) and adjustable pore structure as the substrate. Carbonization temperature control and a chemical vapor deposition (CVD)-based pore-sealing strategy were combined to tailor the pore structure and optimize sodium storage performance. The results revealed that the size and number of closed pores are determined by the open-pore characteristics of the carbon substrate; specifically, substrates with larger micropores and higher specific surface areas promote the development of a greater number of closed pores of larger diameters. Benefiting from the optimized closed-pore architecture, the sample ZCHC-1200 exhibits outstanding electrochemical performance, delivering a high reversible capacity of 436.5 mAh g −1 , with a plateau capacity of 265 mAh g −1 . At a high current density of 2C, it provides 236.8 mAh g −1 and retains 86.5 % of its capacity after 100 cycles. In situ Raman and ex situ X-ray photoelectron spectroscopy (XPS) analyses revealed that the predominant contributor to the elevated plateau capacity is Na + filling within closed pores. This study offers a novel strategy for designing closed pores through open-pore modulation, shedding light on the development of next-generation hard carbon anodes for SIBs.

In this paper, a novel electrochemical sensor was constructed for the detection of purine bases. Ultrafine carbide nanocrystals confined within porous nitrogen-doped carbon dodecahedrons (PNCD) were synthesized by adding molybdate to ZIF-8 followed by annealing. With MoC-based PNCDs (MC-PNCDs) as the carrier, gold nanoparticles (AuNPs) were deposited on the electrode surface via potentiostatic deposition as the promoter of electron transfer, forming a AuNPs/MC-PNCDs/activated glassy carbon electrode (AGCE) sensor. MC-PNCDs had a large specific surface area, which combined with the excellent electrocatalytic activity of AuNPs, synergistically improved the electrocatalytic activity. The morphology and structure of the electrode surface modifier were characterized by scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray photoelectron spectroscopy, infrared spectroscopy, X-ray diffraction, nitrogen adsorption–desorption analysis, and electrochemical characterization. Under the optimal conditions, the linear detection range of guanine (G) and adenine (A) was 0.5–160.0 μM, and the detection limits (S/N=3) were 72.1 and 69.6 nM, respectively. AuNPs/MC-PNCDs/AGCE was successfully constructed, and was used to simultaneously detect G and A with high sensitivity and selectivity. Moreover, the sensor was successfully used to detect G and A in herring sperm DNA samples. Graphical abstract

Herein, an iron-doped ZIF-8-loaded multi-walled carbon nanotube (FZM) was synthesized and its adsorption performance on tetracycline (TC) was investigated. The experimental conditions (solution pH, temperature, adsorbent dose) were optimized by Box–Behnken design (BBD) in response surface methodology (RSM). The results show that the adsorption effect of TC by FZM is optimal under the conditions of temperature = 298 K, pH = 6, and contact time = 360 min. The adsorption processes of TC by FZM follow the pseudo-second-order (PSO) kinetic and Freundlich isotherm models, indicating that chemisorption is the dominant factor and the adsorption reaction is multi-layer, with a theoretical maximum saturation capacity of 1111.11 mg/g at 298 K. The adsorption thermodynamic results indicate that the adsorption of TC by FZM is a spontaneous and endothermic process. The mechanism of TC adsorption by FZM possibly occurs through hydrogen bonding, surface complexation, π–π interaction, and electrostatic interaction. From the statistical results, the optimal adsorption capacity of TC by FZM is 599.78 mg/g at a pH of 7.1, a temperature of 312.5 K, and an adsorbent dose of 64.43 mg/L, with a deviation of 1.73% from the actual value. Furthermore, regeneration experiments demonstrate that FZM has excellent reusability with a 15% loss of adsorption capacity after four cycles. This study provides some insights to study the adsorption behavior of TC by MOFs and the optimization of the adsorption experimental conditions, and also shows the potential of FZM for TC removal.

In this work, a zeolitic imidazolate framework-based graphene oxide composite (ZIF-8@GO) was prepared and used as the adsorbent in hollow fiber stir bar sorptive extraction. The stir bar was constructed of a small section of hollow fiber filled with 5 mg ZIF-8@GO and a thin stainless wire of 1.5 cm long in its lumen, and used to extract the trace levels of phthalate esters from children’s food samples prior to gas chromatography–mass spectrometric detection. The ZIF-8@GO showed a high adsorption efficiency for the compounds containing aromatic rings. The main experimental parameters that can impact the extraction efficiency including extraction temperature, extraction time, stirring rate, sample salinity, and desorption conditions were investigated. Under the optimized conditions, the limits of detection (LODs) for the five phthalate esters (diethyl phthalate, dipropyl phthalate, diisobutyl phthalate, butylbenzyl phthalate, and di(2-ethylhexyl) phthalate) were 0.15–0.6 µg L −1 for CiCi beverage and pear juice samples, and 0.75–2.2 µg kg −1 for jam samples. The limits of quantitation (LOQs) were 0.5–2.0 µg L −1 for CiCi beverage and pear juice samples, and 2.5–7.5 µg kg −1 for jam samples. Wide linear ranges of 0.5–500.0 µg L −1 and 2.5–2000 µg kg −1 were obtained for CiCi beverage, pear juice samples and jam samples, respectively, with good repeatability (RSD < 11%) and high method recoveries (72%–100%). The lifetime test results showed that the ZIF-8@GO-based hollow fiber stir bar can be reused for 120 extraction cycles without a significant loss of extraction efficiency, indicating its high durability and stability. The established method was applied successfully for the determination of the phthalate esters (PAEs) in children’s food samples. Graphical abstract

Composite material (PGPI) of polyimide (PI) modified by C.I. Pigment Green 8 (PG8) were prepared by solid-phase thermal polycondensation, impregnation and thermal treatment. The introduction of PG8 enhanced the π-π stacked crystalline structure and the visible light absorption of PI. The photo-Fenton synergistic system can effectively increase the decomposition efficiency of H 2 O 2 , accelerate Fe 2+ /Fe 3+ cycling and reduce the recombination of photogenerated carriers. The synergistic oxidative removal of TH (Tetracycline hydrochloride, 50 ppm) by PGPI after 40 min under visible-light irradiation was 95.1 %, which was significantly better than that of the photocatalysis alone (40.7 %) and the Fenton reaction alone (55.0 %).

Targeted autophagy regulation holds great promise for antitumor therapy, whereas conventional single-modal autophagy interventions easily induce compensatory escape of tumor cells and fail to transform protective autophagy into a lethal phenotype. In this study, a near-infrared (NIR)-responsive polypyrrole/zeolitic imidazolate framework-8 (PPy/ZIF-8) nanoparticle was successfully fabricated. This nanoplatform enables synergistic and precise regulation of autophagic flux, which amplifies upstream autophagy activation and blocks downstream autophagic pathways simultaneously. The incorporation of PPy endows the nanoparticle with excellent near-infrared absorption capability and photothermal effects. It boosts interfacial electron transfer and optimizes electron-hole separation, further enabling the nanoparticles to possess ROS generation ability. Under 808 nm laser irradiation, the generated ROS and zinc ions induce mitochondrial damage to amplify upstream autophagic signals, whereas the photothermal effect impairs lysosomal function and blocks the downstream degradation of autophagosomes. This dual regulatory strategy causes pathological accumulation of autophagosomes and ultimately triggers autophagic cell death in tumor cells. This work validates the feasibility of integrated autophagy regulation and provides a facile and versatile strategy for the design of advanced multimodal antitumor nanotherapeutics.

An adsorption-triggered mechanism was proposed for on-demand release. • Acidic sites on ZSM-5/ZIF-8 possess stronger adsorption energy for biogenic amines than CA. • The mechanical and gas barrier of film were improved after introducing ZSM-5/ZIF-8. • The developed packaging effectively prolonged fish preservation at 4 °C. Active packaging with on-demand release capability has attracted increasing interest in food preservation; however, the delayed response of active agents often compromises protection during the early stage of spoilage. In this work, an adsorption-triggered release strategy was proposed by incorporating cinnamaldehyde (CA)-loaded ZSM-5/ZIF-8 nanoparticles (CA@ZSM-5/ZIF-8) into a sodium alginate (SA) matrix. Owing to the strong affinity of biogenic amines toward the adsorption sites of ZSM-5/ZIF-8, low concentrations of histamine could competitively displace the preloaded CA, thereby enabling an early and responsive release behavior. In the absence of histamine, the cumulative release of CA from the composite film remained below 10% within 12 h, whereas it increased to approximately 60% in the presence of 5.0 mM histamine. Meanwhile, the optimized film exhibited improved tensile strength (54.6 MPa), water vapor barrier performance (0.86 × 10 −10 g·m·m −2 ·s −1 ·atm −1 ), UV-shielding capability, and water resistance. The film also showed pronounced antioxidant activity (91.4%), sustained antibacterial effects against E. coli and S. aureus , and favorable biodegradability. When applied to fish preservation, the optimized film effectively extended the refrigerated shelf life to 6 days at 4 °C. This study provides a novel paradigm for on-demand release in intelligent food packaging.

Natural antioxidants are limited in food packaging due to poor stability and compatibility. A multifunctional film was successfully prepared via the incorporation of functional fillers into a guar gum/polyvinyl alcohol (GP) matrix. ZIF-8 was amino-functionalized to enhance rutin (Rt) loading, and the resulting ZIF-8-NH2@Rt was combined with purple sweet potato anthocyanins (PSPA) to fabricate a composite film for pork freshness monitoring. Compared with neat GP, the ZIF-8-NH2@Rt/PSPA/GP film showed a 30.6% increase in tensile strength and an elongation at break of 36.6%. The composite film also imparted exceptional UV-blocking capabilities, with light transmittance plummeting to 3.22% in the UVA region, 0.40% in the UVB region, and 47.53% within the visible light spectrum. The films displayed significant antioxidant properties, with DPPH and ABTS scavenging activities recorded at 73.27% and 67.64%, respectively. During pork storage, the film exhibited stable color changes. The G/R values corresponding to the limit of edibility were determined to be 0.78 and 0.67 for storage at 25 °C and 4 °C, respectively. The film was reusable for four cycles and extended the shelf life of pork by at least one day. These findings highlight the film’s considerable promise in the realm of smart food packaging and dynamic freshness tracing.

Yolk-shell magnetic ZIF-8@MOF-74 was synthesized and utilized as a magnetic solid-phase extraction (MSPE) adsorbent for the detection of benzoylurea insecticides (BUs) residues in freshly-squeezed fruit and vegetable juices. The fabrication of magnetic ZIF-8@MOF-74 was conducted under mild and simple conditions without high-temperature/pressure or energy-intensive equipment. With a large specific surface area (880.78 m 2 g −1 ) providing abundant adsorption sites, the mesoporous architecture (average pore size 2.57 nm) and yolk-shell structure of magnetic ZIF-8@MOF-74 enable efficient mass transfer, achieving equilibrium within 7 min as an MSPE adsorbent for BUs. The established analytical method demonstrates good linearity in the concentration range of 0.5–200 μg L −1 , with low limit of detection (LOD) between 0.1 and 0.3 μg L −1 . The recoveries of BUs in freshly-squeezed pear juice and tomato juice samples were in the range of 81%–114% and 102%–120%, respectively.

Synergistic coating design combining ZIF-8 and PDMS on a porous PI substrate. • Integrated multifunctionality enabling oil-water separation, photocatalytic degradation, and anti-bioadhesion. • Exceptional separation performance with a water contact angle of 162.8° for various oil-water mixtures. • Outstanding environmental durability demonstrated against mechanical abrasion, UV aging, and acid/alkali corrosion. The treatment of wastewater containing oils and organic pollutants remains a critical environmental challenge. Traditional separation membranes often lack the multifunctionality needed for simultaneous separation, degradation, and antifouling. In this study, a robust superhydrophobic composite membrane was fabricated via a facile solution-impregnation method, in which zeolitic imidazolate framework-8 (ZIF-8) nanoparticles were integrated with polydimethylsiloxane (PDMS) onto a porous polyimide (PI) substrate. The designed coating synergistically combines the micro-/nano-scale roughness of ZIF-8 with the low surface energy of PDMS, endowing the membrane with a water contact angle of 162.8 ± 0.3° and a sliding angle of 3.0 ± 0.4°. The composite membrane demonstrates high-efficiency separation of various oil-water mixtures (>95% efficiency, flux >9000 L·m −2 ·h −1 ), effective photocatalytic degradation of methylene blue (MB) under ultraviolet (UV) light (93.7% within 2.5 h), and excellent anti-bioadhesion performance against Chlorella vulgaris. Moreover, the membrane retains its superhydrophobicity after mechanical abrasion, tape peeling, UV aging, and exposure to acidic/alkaline environments, confirming outstanding durability. This work presents a scalable strategy for developing multifunctional PI-based membranes with integrated separation, catalytic, and antifouling properties, showing promising potential for practical water remediation applications.

Hepatic diseases present a significant global public health challenge, with cadmium (Cd) and excess molybdenum (Mo) were identified as major environmental toxicants contributing to liver injury. Nevertheless, their precise mechanistic pathways remain incompletely understood. Hence, the hepatotoxicity mechanisms of Mo and Cd were roundly analyzed by network toxicology in this research, the analysis confirmed that these metals primarily induce liver injury through endoplasmic reticulum (ER) stress, apoptosis and necroptosis. Experimental validation further demonstrated that Cd and Mo jointly induce ER stress-mediated apoptosis and necroptosis in duck hepatocytes, and Caspase-8 restrains necroptosis via cleaving RIPK1 and mediates RIPK1-dependent apoptosis, suggesting Caspase-8-mediated proteolytic cleavage of RIPK1 acts as a critical regulatory switch between these two modes of programmed cell death. This investigation additionally elucidated the hepatotoxic mechanisms of Cd and Mo in poultry, and established an academic basis for developing therapeutic interventions against liver pathologies induced by Mo and Cd.

To address the issues of poor cycling stability and unrealized theoretical capacity of layered molybdenum disulfide (MoS 2 ) as an anode material—caused by severe volume expansion during charge/discharge processes—we innovatively propose a "partial carbonization" modification strategy for ZIF-8 templates. This approach successfully constructs a ZnS/NC "dodecahedral nursery" rich in active sites. Benefiting from the abundant anchoring sites provided by this structure, MoS 2 can uniformly and firmly "take root" on the "nursery" via Mo–N bonds, ultimately forming a composite material (ZnS/NC@MoS 2 ) in which MoS 2 nanoflowers uniformly coat the dodecahedral framework. This composite effectively mitigates the volume expansion of MoS 2 and enhances overall structural stability. Moreover, the zinc retained by the partial carbonization strategy, after sulfidation, contributes additional capacity via conversion reactions, further enhancing the material's electrochemical performance. Specifically, when used as an anode for lithium-ion batteries (LIBs), it maintains a specific capacity of 895.64 mAh g −1 after 1200 cycles at 2 A g −1 ; for sodium-ion batteries (SIBs), its specific capacity increases from 348 mAh g −1 to 510 mAh g −1 after 500 cycles at 1 A g −1 .
