Soft capacitive pressure sensors have been widely utilized in the fields of flexible electronics and smart devices. While expanding its pressure sensing range, enhancing the sensitivity of sensors has attracted attention. Currently, the problems that need further solution also include improving the pressure sensing linearity and force detection resolution, enabling sensors to identify tiny pressure changes under high pressure. To address this issue, this study presents a strategy utilizing direct ink writing (DIW) 3D printing technology to construct a double-sided sawtooth structure, which can significantly enhance sensitivity while improving pressure resolution. Traditional flexible dielectric layers are mostly bulk polymer. As the applied pressure increases, the compression of the dielectric layer reduces the distance change between the electrode plates under the same pressure, making it difficult to achieve linear variation of capacitance. This paper designs a double-sided sawtooth structure, which squeezes out the air in the dielectric layer with the increase of pressure to realize linear detection of a wide range of pressures. The thermal expansion microspheres (TEM) introduces micro-pores in PDMS to further expand the linear detection range. In addition, the interfacial polarization effect of CB is utilized and improve the sensitivity. Comparing the double-sided sawtooth structured sensors based on PDMS, PDMS&TEM and PDMS&TEM&CB, the results show that the PDMS&TEM&CB sensor exhibits the highest sensitivity (6.8 × 10 −3 kPa −1 ), excellent linear response across a wide pressure detection range of up to 150 kPa, ultra-low detection limits (∼3.2 Pa), and outstanding dynamic response and repeatability (over 8000 cycles). Additionally, the high pressure resolution of the sensor renders it exceptionally suitable for various applications, including minute pressure detection, spatial pressure mapping, Braille recognition, and mapping changes in object curvature.

The accelerating demand for sustainable, high-rate, and durable energy storage underscores the need for carbon electrodes that simultaneously offer balanced micro–mesoporosity for rapid ion transport and robust heteroatom functionalities for enhanced interfacial chemistry. In the present work, we convert bitumen asphaltenes and recycled cellulose acetate into N/S co-doped hierarchical carbons via ammonium persulfate-assisted co‑carbonization and KOH activation. The optimized carbon combines an ultrahigh specific surface area of 3527 m 2 g −1 , balanced micro–mesoporosity, and uniformly distributed electroactive N/S species (pyridinic/pyrrolic N, C S, SO x ), enhancing conductivity and pseudocapacitance. In three-electrode tests, the electrode delivered 382.5 F g −1 at 0.5 A g −1 with 74% retention at 10 A g −1 . The symmetric aqueous device achieved a specific capacitance of 288.2 F g −1 at 0.5 A g −1 , energy densities of 10.01 Wh kg −1 at 257.4 W kg −1 and 5.42 Wh kg −1 at 6728.3 W kg −1 , and 108.7% capacitance retention after 10,000 cycles at 5 A g −1 . This study advances sustainable energy storage by enabling low-cost, high-performance supercapacitors and promoting solid-waste recycling.

Chlortetracycline (CTC), a broad-spectrum veterinary antibiotic, poses serious risks to human health through bioaccumulation due to excessive use. To address the critical need for CTC monitoring, we developed a fluorescence quenching lateral flow immunoassay (FQ-LFIA) employing black bimetallic hollow nanoparticles (BBHNPs) as quencher. BBHNPs were engineered with a unique dual-advantage architecture: an internal hollow structure for enhanced light capture capability and an external polydopamine layer for higher spectral overlap with fluorophores. This design resulted in exceptional photophysical characteristics, including a remarkable molar extinction coefficient (2.18×10 12 L mol -1 cm -1 ) and an unprecedented fluorescence quenching constant (5.20×10 13 L mol -1 ). BBHNP-based FQ-LFIA achieved a limit of detection (LOD) of 0.32 ng mL -1 , representing a 6.91-fold improvement over conventional gold nanoparticle-based lateral flow immunoassay (LFIA). Validation studies in spiked milk samples showed excellent recovery rates (87.73-118.09%) with high precision (coefficient of variation < 10.36%). Method comparison with liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis confirmed the reliability of BBHNP-FQ-LFIA for real-world applications.

In this study, metabolomics (MET) and flavoromics (FLA) were used to comprehensively characterize the meat quality indicators, metabolites and flavor compounds of two muscles of Wuhuang (WH) pig, a newly recognized local breed in China. The results showed that the pH value of WH pork was in the range of 5.57–6.17 with the pH of the longissimus dorsi muscle (LDM) decreasing rapidly, while that of the psoas major muscle (PMM) remained stable. At the same time, the two meats showed obvious differences in meat color, with a higher Lightness ( L∗ ) value of LDM, a higher a value of PMM, and a stronger sweetness and citrus flavor of LDM. 1-hydroxy-2-Propanone; L-valine ethyl ester; L-Leucine ethyl ester were the main differentiating compounds between the two meats. Phosphatidyl acids, sphingolipids, nucleosides, nucleotides and their analogues were significantly different in the two muscles. Correlation analysis reveal a close association between the above metabolites, flavor compounds, pH value, and meat color. WH pork has excellent quality traits, unique flavor characteristics and high flavor genetic stability. This study provides a theoretical basis for the research, development and utilization of WH pork quality.

In recent years, with the deepening of sustainable development concepts, polyvinyl alcohol (PVA) has garnered widespread attention as a biodegradable, non-toxic material. However, its inherent flammability significantly limits its practical applications. Developing flame-retardant PVA materials suitable for melt processing while maintaining their tensile properties remains a major challenge for practical PVA applications. This study synthesized a novel, highly thermally stable, eco-friendly bio-based flame retardant, CADCM, which was incorporated into the PVA matrix via melt processing. Results indicated that with the addition of just 12.5 wt% CADCM, the PVA composite achieved a limiting oxygen index (LOI) value of 30.3% and a vertical combustion test UL-94 rating of V-0. Reductions of 66.1% in the peak heat release rate (pHRR) and 31.7% in total heat release (THR) were observed compared to PVA0. This demonstrates that the synthesized flame retardant CADCM is suitable for preparing PVA composites with excellent flame retardancy via melt processing. Regarding mechanical properties, the composite exhibited improvements of 27.4% in tensile strength and 285.2% in elastic modulus. In terms of processing performance, the processing melting temperature of the PVA composite with CADCM addition remained suitable for processing requirements, maintaining good processability. The bio-based melt-processable flame-retardant PVA composite prepared in this study provides a feasible pathway and new insights for further expanding the scope of practical application fields of PVA materials.

The development of highly sensitive and selective gas sensors for detection of nitrogen dioxide (NO 2 ) is imperative for environmental monitoring and industrial safety. Herein, we report a novel multi-dimensional heterostructure, 1D MXene (Ti 3 C 2 T x ) nanofibers were derived from 2D MXene (Ti 3 C 2 T x ) through alkaline treatment, then integrated with 0D ZnO nanoparticles for high-performance NO 2 sensing. The unique architecture synergistically combines the high carrier mobility and abundant surface functional terminals of MXene (Ti 3 C 2 T x ) with tunable semiconducting characteristics of ZnO. Benefiting from enhanced charge transfer at the heterointerfaces and maximized active sites, optimized sensor demonstrates exceptional responses to NO 2 at room temperature, realizing a substantial response value of 64.58% towards 50 ppm NO 2 , significantly surpassing pristine MXene (Ti 3 C 2 T x ). Notably, the multi-dimensional composite exhibits an ultra-low limit of detection of 25.14 ppb for NO 2 , which meets the requirements for ppb-level detection. Additionally, the response of sensor to NO 2 (64.58%) significantly exceeds that to other interfering gases at equivalent concentrations, such as NH 3 (0.7%) and trimethylamine (7.3%). Furthermore, during long-term stability testing, the response to NO 2 at equivalent concentrations exhibited only a 4.7% decay over approximately 30 days. Density functional theory calculations reveal that the binding energy of this multi-dimensional structure for NO 2 is 0.5 eV, significantly higher than that for other gas species. Theoretical simulations reveal that improved performance originates from strengthened NO 2 adsorption energy and modulated electron depletion layers at hybrid interface. This work provides viable solution for fabricating advanced gas sensors through multi-dimensional material engineering, demonstrating great potential in real-time air quality analysis.

Hydrophobic surfaces can spontaneously remove water and dust from surface due to their unique "Lotus Effect", offering significant value in self-cleaning, anti-icing, drag reduction, and anti-contamination fields. However, compared to natural hydrophobic surfaces, artificially engineered counterparts often suffer from inherent limitations, among which the rapid degradation of hydrophobicity remains one of the most critical barriers to their widespread application. Moreover, the underlying mechanism governing this decay process is still not sufficiently clear. To address these challenges, we propose to divide wetting behavior into two categories: equilibrium wetting and non-equilibrium wetting. The proposal suggests that the accumulation of contaminants under non-equilibrium wetting conditions plays a pivotal role in the deterioration of surface hydrophobicity. Based on this insight, we develop a water-based coating which can generate spontaneous water-detachment surface that is resistant to calendar aging and can maintain a durable hydrophobic effect under diverse outdoor climate conditions.

This study investigated the CO 2 adsorption performance of seven adsorbent materials with diverse pore structures and chemical compositions over 213 K to 423 K. For zeolite-templated carbon (ZTC), coconut shell activated carbon (CSAC), MOF-199, and MIL-101, the CO 2 uptake increased rapidly in an exponential manner as the temperature decreased. In contrast, coal-based activated carbon (CBAC), 13×, and 5 A zeolite exhibited a slower, linear increase in adsorption capacity. Linear regression and statistical analyses revealed that this difference in temperature sensitivity was likely associated with a shift in the dominant CO 2 adsorption mechanism: from adsorption heat-driven interactions at above-ambient temperatures (303–343 K) to a pore-filling mechanism at sub-zero temperature conditions (213–243 K). Further analysis revealed that at 213 K, micropores with diameters up to 2.00 nm contributed to CO 2 adsorption, whereas at 243 K, only pores smaller than 1.15 nm remained effective. This indicated that as the temperature increases, the effective pore size for pore filling narrows, and above 273 K, pores larger than 0.85 nm no longer contribute to this mechanism. Moreover, density functional theory (DFT), molecular dynamics (MD) and Grand Canonical Monte Carlo (GCMC) calculations supported that the pore-filling mechanism of ZTC became significant only at relatively low temperatures (< 277 K). Nevertheless, owing to its large nonpolar carbon surface and micropore volume, ZTC exhibited a rapid increase in CO 2 uptake once the pore-filling mechanism was activated. This study quantitatively delineated the temperature-dependent transition in CO 2 adsorption mechanisms and provided quantitative guidance for selecting and designing CO 2 adsorbents optimized for different operating temperatures, particularly for sub-ambient applications such as direct air capture in cold climates.

Polyurethane (PU) adhesives hold significant promise for interfacial applications due to their tunable soft-hard segment design. However, the sustainability of conventional PU adhesives is constrained by their reliance on petroleum-derived feedstock, while their adhesion strength is significantly undermined in humid or underwater environments due to competitive interfacial water. Herein, we report a two-step strategy that integrates the glycolysis of waste polyethylene terephthalate (PET) with bio-inspired dopamine grafting to fabricate a catechol-functionalized polyurethane adhesive with robust and repeatable wet adhesion. Waste PET was first glycolyzed and the product was purified via silica gel column chromatography. The resulting glycolytic liquid product (GLP) was employed as a chain extender. Dopamine was then grafted onto the PET-based polyurethane backbone to introduce catechol functionalities, yielding a dopamine-grafted adhesive (C-GPUD). The catechol groups not only interact with urethane groups via hydrogen bonding but also undergo conformational adaptation, oxidative cross-linking, and metal chelation. These synergistic effects collectively enhance both the cohesive strength and the interfacial bonding. The optimized C-GPUD 10 adhesive exhibited rapid and robust adhesion on various substrates in underwater scenarios. It demonstrated excellent repeatable adhesion in tap water, retaining a lap shear strength of 0.21 MPa after ten peeling cycles, which corresponds to 45.7% retention of the initial strength. This outstanding performance enables C-GPUD to effectively seal liquid and gas leaks, demonstrating considerable potential for applications in emergency sealing and underwater repair.

Inefficiency in photogenerated charge separation, especially within the in-plane heptazine units of widely used carbon nitride semiconductors, severely restricts photocatalytic H 2 evolution. Herein, a dual electric field was constructed in a novel C 3 N 4 /C 3 N 5 /CoP (CNHJ- X /CoP) composite via the synergistic integration of a C 3 N 4 /C 3 N 5 homojunction and a C 3 N 5 /CoP Schottky junction. The optimized CNHJ-5/CoP exhibits a photocurrent density 7.5 times higher than that of pure C 3 N 5 , along with a hydrogen evolution rate of 1878 μmol·g −1 ·h −1 (apparent quantum efficiency = 14.1% at 400 nm), which is 24.5% higher than that of C 3 N 5 /CoP binary composite. X-ray photoelectron spectroscopy, density functional theory calculations, and charge dynamics characterization collectively confirm that the dual electric field enhances the in-plane charge separation efficiency within the C 3 N 5 heptazine units and facilitates the directional transfer of photoelectrons from C 3 N 5 to both C 3 N 4 and CoP. Specifically, the homojunction promotes the retention of more holes in C 3 N 5 for reaction with triethanolamine, while the Schottky junction accelerates electron transfer to CoP for H 2 evolution, thereby driving the forward reaction. This work provides new insights into the design of advanced dual-electric-field systems for enhancing charge separation in two-dimensional nanosheets, thereby boosting photocatalytic H 2 evolution.

In the nervous system, neuronal action potentials induced by stimulation reach axon terminals, triggering neurotransmitter release and propagating signals across the neural network. Inspired by neural signal transduction mechanisms, this study designs a responsive self-healing coating synergizing active and passive corrosion protection. A conductive polyaniline-grafted chitosan hydrogel network is integrated into a waterborne epoxy resin matrix via hydrogel coating technology. The inhibitor 2-mercaptobenzothiazole (MBT) is vacuum-encapsulated and deposited onto 304 stainless steel by spin-coating. Combined with first-principles calculations, it was demonstrated that this network rapidly responds to the local pH decrease caused by corrosion near metastable pitting sites on the metal, promptly releasing the vacuum-encapsulated MBT inhibitor. Vacuum-encapsulated MBT is rapidly released by the network in response to local pH reduction caused by corrosion near metastable pits, and the inhibitor is swiftly transported through its channels, enabling the coating to exhibit superior corrosion resistance during long-term immersion in 3.5 wt% NaCl solution. Electrochemical impedance spectroscopy (EIS) confirms exceptional corrosion resistance, with |Z| 0.01Hz maintained at 7.54 × 10 8 Ω·cm 2 after 35 days. Scratch tests demonstrate effective self-healing, as |Z| 0.01Hz increases to 4.97 × 10 7 Ω·cm 2 within 14 h. The value is about two orders of magnitude higher than that of the blank coating. Neural network signal transduction principles establish innovative frameworks for advancing metallic protection methodologies.

Perovskites have attracted considerable interest as potential photocatalysts for sustainable hydrogen generation. Nonetheless, their intrinsic instability in aqueous media significantly constrains their practical deployment in photocatalytic hydrogen evolution. To address this challenge, we propose a versatile strategy for stabilizing Cs 3 Bi 2 Br 9 (CBB) perovskite photocatalysts through combining zwitterionic ligand encapsulation with Sn 4+ doping. The zwitterionic ligand, synthesized by reacting 4-bromobutyric acid (BBA) with oleylamine (OLA), was employed to passivate the perovskite surface by anchoring to both Bi 3+ and Br − sites, effectively mitigating surface defects. Notably, Sn 4+ doping is essential for aqueous stability, as the incorporation of Sn 4+ not only enhances the intrinsic stability of CBB but also reinforces the binding affinity of surface ligands. As a result, the Sn 4+ -doped CBB (CBBS x ) with ligand encapsulation demonstrates remarkable stability, retaining its structural integrity in water for over six months and withstanding more than three cycles of photocatalytic testing. Importantly, this strategy demonstrates considerable generality, as it can be readily extended to the synthesis of other halide perovskites. Specifically, the MoS x -loaded Sn 4+ :Cs 3 Bi 2 Br x I 9-x (MoS x /CBBIS 0.2 ) composite achieves a remarkable hydrogen evolution rate of 18.2 mmol h −1 g −1 , which represents the highest performance reported to date among Bi-based perovskite photocatalysts.
