The key component that guarantees a stable cycle for lithium-ion batteries (LIBs) is the Solid Electrolyte Interphase (SEI) membrane, which possesses remarkable mechanical properties. A good SEI film can reduce the migration energy of Li + and support the even deposition of Li + onto the lithium anode. In this paper, polyethylene oxide (PEO)-Lithium bis((trifluoromethyl)sulfonyl) azanide (LiTFSI) was used as the surface modification layer of the poly ( m -phenylene isophthalamide) (PMIA) separator. The PEO-LiTFSI functional layer was applied onto the surface of PMIA separator through hydrogen bond interaction. The introduction of the PEO-LiTFSI functional layer promotes the interaction between the PMIA separator and the electrolyte, improves the porosity of separator, subsequently boosts the liquid absorption rate and electrolyte retention rate, and minimizes the migration resistance of Li + . PMIA/LiTFSI composite separator has a lower interface impedance (174.7 Ω). More importantly, the presence of LiTFSI leads to the development of a LiF-rich SEI film on the surface of lithium anode, which promotes the movement of Li + near the lithium anode and improves the structural stability of the SEI membrance, showing a longer service life of LIBs. Through long cycle test, it was found that the LFP||Li battery that employed the PMIA/LiTFSI composite separator still had a capacity retention rate of 95.4 % along with a specific discharge capacity of 133 mAh g −1 after undergoing 100 cycles.

Biodegradable and edible packaging films derived from konjac glucomannan (KGM) are gaining popularity as promising candidates to replace petroleum-based plastics with the aim of alleviating environmental problems. However, their poor mechanical strength and lack of antioxidant activity have restricted their practical application in food packaging. Bacterial cellulose (BC), with a three-dimensional nanostructure and biodegradable and biocompatible properties, was chosen as a reinforcing agent to enhance the mechanical properties of KGM film. Film prepared with 15% BC displayed the highest tensile strength of 62.87 MPa and elongation at break of 38.17%, owing to the strong hydrogen bond interactions between the BC and KGM chains. Furthermore, tea polyphenols (TP), a type of natural antioxidant agent, were incorporated into the BC and KGM composite films and endowed films with excellent antioxidant properties, with scavenging rates toward DPPH and ABTS free radicals of up to 96.74% and 97.50%, respectively. Meanwhile, the mechanical strength, UV shielding performance, and water-vapor and oxygen barrier properties of the films were also improved through the incorporation of TP. The film was successfully applied as a packaging material for fresh-cut apple preservation. The prepared film demonstrated nontoxicity and excellent biodegradability over 28 days, with no significant impact on plant growth. Therefore, the prepared composite film exhibited great prospects as a novel type of biodegradable, sustainable and bioactive film for food preservation.

Monitoring internal physiological signals is essential for effective medical care 1 , yet most current technologies rely on external measurements or imaging systems that cannot capture enough deep-tissue dynamics 2 , 3 , 4 , 5 , 6 . Implantable devices offer a solution, but conventional designs often require batteries or magnets 7 , 8 , 9 , 10 , 11 , which carry risks during removal, and existing biodegradable sensors based on passive inductor–capacitor circuits are limited by short readout distances and unstable communication issues 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 . Here we describe a soft, biodegradable, wireless sensing device that can monitor pressure, temperature and strain over long distances (up to 16 cm), maintaining accuracy across varying positions and angles. This is achieved through a ‘pole-moving sweeping’ readout system combined with a folded structure that integrates mechanical flexibility with electromagnetic function. In vivo tests in the abdominal cavity of horses reliably captured deep-tissue pressure and temperature, and ex vivo measurements demonstrated accurate strain monitoring without strict positional control. The long-distance and wide-angle readout of soft biodegradable implants holds translational promise for accessing deep-tissue physiological signals.

This study used chitosan (CS) and gelatin (GL) as base materials and employed emulsion encapsulation technology to prepare films with citrus essential oil (CEO) as an antimicrobial agent. The results showed that the CEO emulsion was uniformly distributed throughout the interior and surface of the film, promoting the formation of a thicker and rougher layered porous structure, which significantly improved the film's elongation at break and water resistance. Additionally, the addition of the CEO emulsion significantly improved the film's thermal stability, enhanced its UV resistance, antioxidant properties, and antibacterial performance. In practical applications, the CG/WO-7 % composite film inhibited the respiration of blueberries, reduced weight loss and nutrient loss, enhanced their antioxidant enzyme activity, and suppressed the excessive accumulation of ROS. Compared with the control group, the treatment with CG/WO-7 % film extended the shelf life of blueberries by 3 days, from 5 days to 8 days.

Conventional plastic mulch films contribute to persistent soil pollution due to their poor biodegradability. To address this issue, this study developed a biodegradable mulch film with improved overall performance using co-milling technology and an ionic cross-linking strategy. Ultrafine tobacco stalk powder (TSC) was efficiently prepared through co-milling with calcium carbonate, reducing particle size to approximately 25.41 μm. Composite films were fabricated by incorporating TSC into a polyvinyl alcohol (PVA) matrix plasticized with glycerol, followed by Fe 3 ⁺ cross-linking treatment. The optimal TSCF 30 -Fe film exhibited a well-balanced combination of strength, flexibility, and stiffness, with a tensile strength of 11.8 MPa, elongation at break of 123%, and Young's modulus of 42.1 MPa. The Fe 3 ⁺ coordination formed a cross-linked network that enhanced mechanical strength and water resistance, accompanied by a reduced swelling ratio. Furthermore, the composite films demonstrated excellent UV-shielding capability, with strong UV-shielding capability across the 200–400 nm range. Surface hydrophobicity increased with increasing TSC content, which was attributed to the presence of lignin hydrophobic groups. Soil burial tests confirmed biodegradability, showing progressive surface erosion, pore formation, and a continuously increasing degradation rate, whereas commercial films remained intact. This study presents a sustainable approach for valorizing agricultural waste and offers a sustainable strategy for agricultural waste valorization and provides useful insight into the development of biodegradable mulch film materials.

This study reports an eco-friendly sensing film composed of soy protein isolate, zinc alginate, eggplant peel extract, and N-doped carbon dots designed for pork freshness monitoring. The film integrates fluorescence and colorimetric responses to enable dual-mode, pH-sensitive detection and exhibits stable optical behavior across a wide pH range (2.0–12.0). The film also responds linearly to NH 3 over a concentration range of 0–1000 ppm (R 2 = 0.97528, LOD = 8.68 ppm), with distinct and visible color changes observed at higher concentrations (500–5000 ppm). The film effectively preserved pork quality, as indicated by a 50% reduction in fluorescence intensity at 25 °C after 48 h, and maintained stable fluorescence for up to 36 h at 5 °C prior to spoilage onset. Under 5 °C, it contributed to a 3.9% reduction in pH. This film provides an effective and non-invasive solution for real-time, on-site meat freshness assessment and food waste reduction.

Effective freshness monitoring is essential for aquatic products to ensure food safety and reduce waste. To overcome the limitations of stability and sensitivity in colorimetric films, we developed a novel composite film by integrating a tannic acid-Fe 2+ (TF) chelate with deep eutectic solvents (DESs) in a polyvinyl alcohol matrix. The TF chelate served as multifunctional indicator, providing distinct color responses to NH₃, DMA, and TMA while enhancing hydrophobicity, UV-blocking, and thermal stability. DESs incorporation significantly improved mechanical properties (elongation at break up to 600%) and drastically enhanced sensitivity, enabling visible color changes within 1 min due to increased surface roughness (1.78 to 3.97 nm), hygroscopicity (1.8% to 5.6% at 33% RH), and water vapor permeability (0.4 to 0.8 g·mm/(m 2 ·h·kPa)). In salmon monitoring, the film showed clear color transitions. Deep learning-assisted analysis achieved over 97% accuracy in freshness classification. Overall, the films show strong potential for freshness monitoring of aquatic products.

Photocatalytic hydrogen production provides a sustainable approach for converting solar energy into clean, high-energy–density hydrogen fuel, addressing both energy shortages and environmental concerns. In this study, three-dimensional ZnIn 2 S 4 nanoarchitectures were grown in situ on TiO 2 nanobelts via a simple oil-bath method, forming core–shell ZnIn 2 S 4 @TiO 2 (ZIS@TO) heterojunctions, with TiO 2 nanobelts as the core and ZnIn 2 S 4 nanoflowers as the shell. The integrated heterojunction combines the structural advantages of both one-dimensional and two-dimensional components. The interface characteristics, band alignment, and charge carrier dynamics of the ZIS@TO were systematically investigated. The results show that the ZIS@TO heterojunction improves the dispersion of ZnIn 2 S 4 and TiO 2 , promoting more efficient interaction between photogenerated electrons and water. Furthermore, the heterojunction facilitates effective charge separation via an S-scheme transfer mechanism, leading to a significantly enhancement in photocatalytic hydrogen evolution activity.

High-performance ammonia (NH 3 ) sensors have significant potential in practical applications, including air quality management, food safety, and health monitoring. In this work, an opulus flower-like sheet-on-sheet heterostructure (ZIS@BVO NS) consisting of BiVO 4 (BVO NS) nanosheets mounted ZnIn 2 S 4 (ZIS) nanoflowers is successfully synthesized using an ultrasound induced self-assembly process for highly sensitive detection of NH 3 . The ZIS@BVO NS sensor exhibited a significantly improved response ( R a /R g = 21.03) to 200 ppm NH 3 at an optimal operating temperature of 202°C, which is three times greater than that of pure BVO NS (7.4) and 8-fold higher than ZIS (2.7), respectively. Additionally, the heterostructure exhibited swift response (8 s) and recovery (13 s) durations. The improved performance was ascribed to the hierarchical nanostructure, which offered numerous active sites, greater surface permeability, and optimized gas diffusion processes owing to open channels and increased chemisorbed oxygen concentration. This study emphasizes an eco-friendly one-step synthesis route of ZIS@BVO NS heterostructure for accurate NH 3 monitoring in food safety, health, and environment, facilitating effective management and the early identification of dangerous ammonia buildup.

Understanding the penetration behavior of flavor additives in tobacco leaf during casing process is crucial for the production of tobacco products. Here, atmospheric pressure laser desorption ionization/post-photoionization mass spectrometry imaging (AP-LDI/PI MSI) was utilized to study the flavor additives penetration in tobacco leaf. The cross section of tobacco leaf with and without flavor additives were scanned by focused laser beam at ambient condition, and the desorbed species were ionized by dopant-assisted post-photoionization setup. The distributions of the endogenous metabolites and exogenous model flavor molecules could be well imaged with 5 μm spatial resolution. It was found that the penetration efficiency varies significantly among different flavor additives. Increased temperature and humidity could enhance penetration efficiency by promoting molecular thermal motion and accelerating cuticle hydration. Finally, the penetration process of a commercial flavor additive solution was visualized and evaluated, which would provide valuable guidance for cigarette casing technology.

Industrial wastewater and oily effluents pose severe environmental and health risks, necessitating efficient and sustainable separation technologies. Polytetrafluoroethylene (PTFE) microporous membranes are among the most widely used separation materials in extensive applications involving separation, filtration, and insulation, but the traditional processing approaches require high energy consumption and large amounts of environmentally unfriendly agents. This study presents a comparatively more environmentally benign strategy to fabricate PTFE nanofibrous membranes via an in-situ fibrillation method with a water-soluble processing agent. The resulting membranes exhibit highly entangled fibrous network microstructures, achieving tunable pore sizes (0.16–1.30 μm), high porosity (72–78%), and excellent mechanical strength (up to 28.6 MPa). Moreover, their hydrophobicity and oleophilicity enable outstanding oil-water separation efficiency (>99%) with gravity-driven fluxes up to 3980 L m −2 h −1 . The membranes exhibit >98% rejection of SiO 2 (dispersed in strong base solutions) and carboxylate CNTs (dispersed in strong acid solutions) under vacuum filtration, while maintaining excellent antifouling performance and recyclability. This work provides a facile and comparatively environmentally benign and scalable route to high-performance PTFE porous membranes, offering promising potential for industrial wastewater treatment, emulsion purification, and solid-liquid separation applications.

Coordination with Cu 2+ induces electronic reconstruction in natural polyphenols, enabling bandgap narrowing and visible-light responsiveness. • Electronic reconstruction promotes intersystem crossing and dual-pathway ROS generation via Type I/Type II photodynamic processes. • The CuL NPs exhibit enhanced photodynamic antibacterial activity and efficient biofilm eradication under visible-light irradiation. • CuL NPs embedded in gelatin/κ-carrageenan films provide interfacial photodynamic antimicrobial protection for fruit preservation. Electronic reconstruction provides an effective route for regulating excited-state dynamics in photodynamic systems but remains difficult to achieve in bio-derived photosensitizers. Here, we reveal an electronic reconstruction effect in natural polyphenols via copper-ion-mediated coordination assembly, enabling catalytically amplified photodynamic antimicrobial activity. Electronic reconstruction enhances spin-orbit coupling and facilitates intersystem crossing (ISC) by lowering the singlet-triplet transition barrier, thereby boosting ROS generation. Spectroscopic characterization and density functional theory (DFT) calculations verify pronounced electronic modulation after coordination, including bandgap narrowing from 2.64 to 1.08 eV and reduction of the HOMO-LUMO gap from 6.22 to 5.09 eV. Coupled with a Cu(I)/Cu(II) photoredox cycle enabling catalytic ROS amplification through synergistic Type I and Type II pathways, the system achieves 99% bacterial inactivation within 20 min and eradicates mature biofilms. When incorporated into a biodegradable gelatin/κ-carrageenan matrix, these nanocomplexes form light-triggered antimicrobial films for fruit preservation. These results highlight coordination-induced electronic reconstruction as a strategy to enhance photodynamic activity in polyphenol-based materials with potential for sustainable bio-derived phototherapeutic and food-preservation platforms.

Conceptual illustration of coordination-driven electronic reconstruction in CuL NPs, their catalytic dual-pathway photodynamic antibacterial/antibiofilm mechanism, and translation into multifunctional GC-CuL composite films for light-responsive fruit preservation.
