Antimicrobial packaging has received extensive attention due to its significant role in ensuring food safety. However, direct contact between liquid foods and antibacterial surfaces often causes food residue and affects the release of antibacterial agents, ultimately deteriorating antibacterial performance. Here, we report a strategy to overcome this imperfection by grafting PDMS molecular brushes onto the thymol-loaded polylactic acid (PLA) films. The PDMS molecular brushes provide the surface with low adhesion to various food droplets (e.g., cola, milk, and vinegar). The sliding angles (SA) for these food droplets are all less than 30°. Meanwhile, it does not affect the release of the antibacterial agent (thymol). Based on these advantages, the film shows enhanced stability in its antibacterial properties, with bactericidal rates against E. coli and S. aureus reaching nearly 100%. The excellent antibacterial performance can be maintained even after contact with liquid foods, as evidenced by the nearly unchanged inhibition zones against E. coli and S. aureus (e.g., the diameter of the inhibition zone against S. aureus is slightly changed from 1.87 nm to 1.83 nm). Moreover, the optimal conditions to fabricate the film were also discussed in detail, such as the content of thymol, the alkaline hydrolysis time, the temperature and time for grafting PDMS molecular brushes. The work reports a strategy to guarantee stable release of the antibacterial agent through grafting PDMS molecular brushes onto packaging films, thereby effectively prolonging the shelf life of liquid foods.

Rapid and timely nucleic acid detection through polymerase chain reaction (PCR) is an urgent demand in epidemic prevention and control. However, conventional Peltier-based PCR instruments are too slow to meet this requirement. Herein, an ultra-fast photothermal real-time quantitative PCR (qPCR) system that integrates a metal-organic framework (MOF)-based photothermal membrane with a silicon-based microfluidic chip is constructed for rapid SARS-CoV-2 detection. After optimization of the synthesis temperature of zirconium-ferrocenyl (Zr-Fc) MOFs and the thickness of Zr-Fc MOF/SWCNTs (ZFC) membranes, the resultant ZFC-22 membrane exhibits excellent and robust photothermal performance with an ultra-fast heating rate of 60.3 °C/s, enabling a rapid heat generation rate. Subsequently, the ZFC-22 membrane is integrated into a custom-designed silicon-based microfluidic chip that not only enhances heat conduction but also effectively confines heat in the PCR microchannel via thermal-isolation grooves, thereby reducing heat loss. Finally, a photothermal real-time qPCR system consisting of photothermal modules, microfluidic chips, control modules, and fluorescence imaging modules is constructed, which completes 40 nucleic acid amplification cycles within 10 min with an excellent amplification efficiency (98.6%), a low limit of detection (10 copies/μL), and an extremely low average optical power (1 W/well).

From the perspective of sustainable energy and green hydrogen, the critical challenge in seawater electrolysis lies in suppressing competitive chloride oxidation and corrosion at the anode. Despite the proposed protection mechanism based on surface reconstruction-derived anion repellence, a fundamental question of selectivity remains: why does the protective layer exclude Cl - but not the formally equivalent OH - ? We now redefine the connection between reconstruction and interfacial protection in NiFeS anodes to elucidate the origin of underlying selectivity. In-situ Raman, in-situ X-ray absorption spectroscopy, and molecular dynamic calculations further confirm that the reconstructed SO 4 2- establishes an enhanced hydrogen-bond network. This network significantly weakens the hydrogen-bonding strength of Cl - relative to H 2 O, thereby enhancing the discrimination between OH - and Cl - . In practical application, NiFeS demonstrates energy-saving seawater splitting performance (261.8 mV @ 100 mA·cm -2 ), long-term durability (2000 h @ 1.0 A·cm -2 ), and enables stable intermittent electrolysis (1500 start-stop cycles @500 mA·cm -2 ). When integrated into an anion exchange membrane cell, it shows promising electrolysis performance for industrial applications (1.970 V @ 1.0 A·cm -2 ).

The increasing influx of nutrients ( e.g. , nitrogen and phosphorus) into freshwater systems is exacerbating eutrophication in natural waterways. To address this issue, a novel magnetic photocatalyst composed of a carbon nanotube core and a titanium dioxide coating (denoted as C–TiO 2 –Fe 3 O 4 and C–TiFe 2 O 4 ) is successfully synthesized. Microcystis aeruginosa and microcystin-LR (MC-LR) in eutrophicated water can be efficiently inactivated by the composite via visible light photocatalysis. The incorporation of magnetic Fe significantly enhances cyanobacteria capture and improves the photocatalytic efficiency for algal inactivation and MC-LR breakdown. C–TiFe 2 O 4 exhibits the highest adsorption-photocatalysis performance with an inactivation efficiency of 77.9% after 7 hours. Under optimal conditions (7 h of reaction time, a catalyst dosage of 0.39 g L −1 , and an initial algae density of 1 × 10 6 cells per mL), the MC-LR removal rate is 89.1%. Notably, C–TiFe 2 O 4 maintains exceptional stability and reusability even after five cycles. The composite demonstrates promising potential for treating harmful algal blooms (HABs) across diverse environmental conditions. These findings highlight the viability of C–TiFe 2 O 4 as a sustainable and scalable technology to mitigate HABs and degrade MC-LR in contaminated water systems. The prepared magnetic photocatalysts, C–TiO 2 –Fe 3 O 4 and C–TiFe 2 O 4 , are sustainable and scalable technologies to mitigate HABs and degrade MC-LR in contaminated water systems.

Nemipterus virgatus surimi gel fabricated by continuous microwave heating (CMH) was characterized for the addition of a Tremella polysaccharide/soy protein isolate Pickering emulsion (TSPE), using free soybean oil (SO) and a physical mixture of TSPE as controls. Compared to free SO, TSPE could significantly ( P < 0.05) improve palatability, with increased mechanical properties, including 21.95% gel strength, 12.67% chewiness, and 6.93% adhesiveness. Addition of 3% TSPE effectively filled the network structure with reduced gel porosity of up to 52.09%, improved water-holding capacity, and minimized cooking loss by converting free water to immobilized water, likely due to a more highly-ordered molecular arrangement with increased β-sheet content. Furthermore, molecular docking analysis showed that Tremella polysaccharide in TSPE could act as an effective emulsifier through binding interactions via carbonyl and hydroxyl groups. The findings above demonstrate the great potential of Tremella polysaccharide-incorporated Pickering emulsions in enhancing the quality of surimi gel.

The selective photooxidation of CH 4 into value-added chemical products under ambient conditions offers a viable pathway for the rational utilization of natural gas resources. However, the direct oxidation of methane to synthesize oxygenates still faces significant challenges due to insufficient chemo-selectivity in active intermediate radical formation and consecutive side reactions of primary products. Rather than introducing multiple metal species to create active sites, we show that controlled defect generation on the substrate offers an effective pathway for catalytic enhancement. Here we developed a ZnO aerogel-supported ruthenium single atom photocatalyst for selective conversion of CH 4 to CH 3 OH. Under ambient conditions, 1Ru/ZnO achieved a methanol production rate of 407 μmol g −1 h −1 with a high selectivity of 91.7%. The observed activity enhancement is principally attributable to two factors: (i) the ZnO aerogel microspheres with abundant dual-defect structures serve as an effective substrate material, offering abundant active sites to facilitate the CH 4 activation process; and (ii) monatomic Ru 4+ sites were employed as efficient active sites for methane adsorption and dehydrogenation; meanwhile the separation of redox sites was optimized to effectively suppress over-oxidation. The integration of aerogels (with abundant defect sites) and supported metal species offers a novel strategy for achieving direct CH 4 oxidation to CH 3 OH.

Hydrogen energy is the core of future clean energy, and the study of hydrogen evolution reaction (HER) electrocatalytic mechanisms is essential for efficient production. The development of efficient and low-cost electrocatalysts is a key challenge in achieving ideal hydrogen generation. In this study, a Ni-BDC/TpPa-1 heterojunction material was prepared for the first time, which was converted into a derived heterojunction material (NiO@Ni/N-C) after high-temperature pyrolysis treatment, exhibiting excellent electrocatalytic activity in an alkaline solution. Without iR compensation, the overpotential of HER is only 83 mV at a current density of 10 mA·cm⁻². Compared with thermally decomposed Ni-BDC and TpPa-1 monomer, its electrocatalytic activity is improved by 158 and 435 mV, respectively, and it exhibits excellent stability over 100 h. The design of this novel material offers a new solution for enhancing the efficiency of transition-metal-based catalysts.

This study systematically compared tobacco extracts prepared by solvent extraction and by pyrolysis in terms of their chemical composition, thermal stability, and pyrolysis product distribution. An innovative, systematic validation framework integrating residue pyrolysis and extract re-pyrolysis was employed to directly discriminate between extraction-induced compositional effects and pyrolysis-condition effects. This framework elucidates intrinsic correlations among extraction methods, chemical composition, and thermal behavior from the perspectives of aroma diversity and phenolic suppression. The results revealed that the extraction yield increased from 7.08 % to 33.48 % with increasing solvent polarity, while pyrolysis achieved an even higher yield (36.80 %) through high-temperature pyrolytic conversion. Solvent extracts exhibited polarity-driven compositional differences, whereas pyrolysis-derived extract (Py-Ext) was enriched in characteristic aroma compounds such as furfuryl alcohol and maltol, and contained more target compounds (19 types) than solvent extracts (9–15 types). Thermal analysis revealed that the solvent extracts decomposed primarily within the 135–279 ℃ range, yielding product distributions that were highly sensitive to pyrolysis conditions. In contrast, Py-Ext exhibited volatility-dominated thermal behavior that resulted in stable product distributions across a broad operational range. Extract re-pyrolysis revealed that the compositional incompleteness of solvent extracts prevents them from achieving the aromatic richness of Py-Ext, even under identical pyrolysis conditions, while residue pyrolysis confirmed that key aroma precursors were retained in the solid phase during extraction. Meanwhile, solvent extraction markedly suppressed phenolic formation during re-pyrolysis through precursor removal at the source. Overall, the proposed validation framework establishes a causal method–composition–behavior relationship, providing a basis for the rational design of tobacco extracts for targeted applications.

Moss-induced biocorrosion of stone heritage is a slow yet persistent deterioration process that alters the physicochemical conditions within porous stones, leading to structural damage and loss of cultural value. To conduct in-situ decoding of the pathogenic mechanism of mosses on sandstone, we developed a fiber Bragg grating (FBG)–based multi-parameter sensing system. The sensing system integrates three types of FBGs—temperature-sensing (T-FBG), strain-sensing (S-FBG), and polyacrylic acid–polyvinyl alcohol (PAA-PVA) coated pH-sensing FBG (H-FBG). The sensitivities and resolutions of T-FBG, S-FBG and H-FBG are 9.69 pm/℃ (0.01 ℃), 1.23 pm/με (0.1 με) and 38.63 pm/pH (0.02 pH units), respectively. A decoupling model based on a 3 × 3 sensitivity matrix was established to eliminate cross-sensitivity effects. During 60 days of Funaria hygrometrica colonization, the system captured dynamic variations including a maximal pH decrease of 0.5, a temperature fluctuation of 3.2 ℃, and an internal microstrain increase of 11.3 με. Microscopic and porosity analyses further confirmed the dual biochemical–mechanical degradation caused by metabolite secretion and rhizoid penetration. This work provides quantitative insights into moss-induced biocorrosion mechanisms and indicates the feasibility of optical fiber sensing as an early-warning strategy for preventive conservation of stone relics.

Radiative cooling offers a promising energy-free thermal management approach for electronic devices. However, the practical application of conventional radiative cooling materials is limited by their low thermal conductivity, leading to heat accumulation from internal sources. In this work, a low-cost and high-thermal-conductivity radiative cooling film (HTCRCF) was developed by introducing three-dimensional (3D) co -doped fillers that consist of BN platelets and spherical Al 2 O 3 particles into a polydimethylsiloxane (PDMS) matrix. In contrast to conventional low-thermal-conductivity materials, the 3D synergistic strategy simultaneously enhances infrared emission, sunlight reflection, and heat conduction at a low cost. The HTCRCF achieves a high solar reflectivity of 93%, an infrared emissivity of 0.95 and a thermal conductivity 2.7 times higher than that of the matrix. Outdoor tests demonstrate radiative cooling performance of 7.8 °C under direct midday sunlight and 2.4 °C at night. Moreover, HTCRCF demonstrates excellent radiative cooling performance higher than the ambient temperature, lowering substrate temperatures by a remarkable 29.7 °C under sunlight and 17.3 °C in indoor environments. This work provides a scalable solution for high-power electronic devices cooling and bridges the gap between radiative cooling efficiency and thermal management requirements in real-world applications.

Bipolar membranes (BPMs) enable efficient water dissociation into protons and hydroxide ions for sustainable energy conversion and resource recovery, yet conventional BPMs face challenges including high overpotential, environmental drawbacks of synthetic polymers, and the conductivity-stability trade-off. Herein, we develop a robust and eco-friendly BPM by in-situ embedding layered double hydroxide (LDH) nanosheets into a fully biomass-derived matrix of polyvinyl alcohol (PVA) and quaternized chitosan (QCS). The optimized membrane (BM-QPL-4) achieves a low transmembrane voltage of 0.746 V at 100 mA·cm −2 and maintains 0.713 V over 72 h at 50 mA·cm −2 , coupled with 40% enhancement in mechanical strength (33.31 MPa) and reduced swelling ratio (61.52%). These improvements arise from the uniformly dispersed LDH, which strengthens the polymer matrix while serving as built-in catalysts and ion-conductive pathways. The synergistic surface hydroxyl catalysis and interfacial electric field—described by “pore-field coupling” model—collectively lower the water dissociation energy barrier from 0.97 eV to 0.56 eV. The work demonstrates a sustainable and mechanically robust BPM platform with great potential in advanced water electrolysis and resource recovery, providing a scalable and generalizable strategy for incorporating functional nanomaterials into polymer matrices.

Astringency, as a complex oral sensation, poses challenges for in-vitro detection and quantification due to the intricacy of its perception mechanism and the complexity of the astringent substances involved. To address this challenge, we developed a chitosan hydrogel-based sensor inspired by the human tongue. Mucins were embedded within the sensor to detect astringent polyphenols. When in contact with astringent phenolic compounds, the resulting precipitate aggregates entangle or block the pores, restricting ion conductivity within the sensor. Astringency detection is achieved using cyclic voltammetry. The tongue-inspired sensor can detect a wide range of tannic acid (1E −4 wt% - 5wt%), including the human sensory threshold for astringency, and construct a standard astringency quantification curve from the sensing data. It was demonstrated to revert the actual astringency sensing process by overall astringency detection and synergistic effect, simulating the in-vitro function of the tongue. In addition, the sensor provides insights for evaluating the optimal drinking time of open red wines based on astringency, offering a novel approach for wine astringency evaluation, demonstrating its potential for a variety of applications in the food and beverage industry.
