Under low-temperature and high-humidity conditions, stable ice layers readily form on asphalt pavements in cold regions, and the enhanced ice–asphalt interfacial adhesion significantly increases deicing difficulty and traffic safety risks. To clarify the factors governing ice–asphalt interfacial adhesion strength, this study combines macroscopic pull-off tests and molecular dynamics simulations to systematically investigate the effects of interfacial contact area, temperature, pull-off rate, and molecular characteristics of representative asphalt components. The pull-off results show that adhesion strength increases markedly with decreasing temperature, rising from approximately 163 kPa at −2 °C to 242 kPa at −10 °C. In contrast, the nominal adhesion strength decreases with increasing ice specimen size, suggesting that size-related interfacial heterogeneity and nonuniform stress transfer may contribute to the pull-off response. The adhesion strength also generally decreases as the pull-off rate increases. Molecular dynamics simulations show that smaller asphalt–ice interfacial models exhibit higher molecular-scale nominal adhesion responses, while temperature-dependent simulations provide short-range asphalt–ice interaction descriptors for interpreting the experimental temperature trend. The calculated short-range asphalt–ice interaction energy becomes less negative from −531.4 to −352.5 kJ mol−1with increasing temperature, supporting the experimentally observed strengthening of adhesion at lower temperatures. Single-molecule pull-off simulations of 12 representative asphalt molecules reveal pronounced molecular differences, with molecular-scale nominal adhesion strengths ranging from 303.7 to 734.6 MPa. Asphaltene and polar aromatic molecules generally show stronger adhesion, which is associated with larger projected contact area, flatter molecular configurations, and heteroatom-induced polar sites. The molecular polarity index shows a moderate positive association with molecular-scale nominal adhesion strength. These results establish a scale-aware mechanistic correspondence between macroscopic pull-off behavior and molecular interaction descriptors at the ice–asphalt interface, providing insights for interfacial adhesion regulation and anti-icing design of asphalt pavement materials in cold regions.

Drug-resistant Staphylococcus aureus (DRSA) infections present a formidable therapeutic challenge severely threatening human health. To address this, we engineered a metal−phenolic network (MPN) platform that co-immobilizes whole-cell DRSA with immunostimulatory metal ions (i.e., Fe3+, Mn2+, Zn2+) under mild conditions. Among these, the iron-coordinated MPN (SA@FeMPN) exhibited superior potency, leveraging a dynamic valence transition mechanism to robustly amplify the TLR2/NF-κB signaling. This mechanism promoted functional polarization of macrophages to the M1 state and drove dendritic cell maturation. In a murine systemic infection model, SA@FeMPN elicited robust cellular and humoral immunity, achieving a 2−18-fold greater reduction in bacterial burden across major organs compared to other MPNs, and established durable immunological memory to prevent infection relapse. Collectively, this work establishes iron-coordinated MPNs as a rational design platform for next-generation immunotherapy and identifies SA@FeMPN as a promising therapeutic vaccine candidate that not only eradicates established DRSA infections but also confers lasting protection against recurrence.

Solar-driven interfacial evaporation, with its zero carbon emissions, low cost, and off-grid characteristics, has become a core solution for seawater desalination and wastewater purification. However, its practical application is still limited by the insufficient freshwater productivity due to the low vapor condensation rate. This study introduces a copper foam (CF)-based bidirectional solar water production (CF-BSWP) device. Utilizing the interconnected networks of CF, the available surface area and nucleation sites for vapor condensation are increased. Furthermore, the CF undergoes hydrophobic modification to suppress the formation of a liquid film, which constitutes a major barrier for continuous vapor condensation. Under 1 sun illumination, the hydrophobic CF-BSWP device achieves a water productivity of 1.20 kg m −2 h −1 and a solar-water efficiency of 80%. Importantly, a 10-hour real-world operation demonstrates an outstanding water yield of 11.07 kg m −2 , suggesting sustainable water production under natural sunlight and fluctuating weather conditions. This work provides an effective and viable solution to harvest the vapor generated in solar-driven interfacial evaporation devices.

Pyrolysis and activation are common methods for preparing biochar adsorbents, but these treatments often increase porosity while destroying oxygen-containing functional groups that are important for pollutant binding. In this work, a non-carbonized strategy was developed to regulate biomass surface chemistry using camphor wood. Instead of thermal treatment, lignin was removed and the material was modified with tannic acid (TA) and Fe 3 + to construct adsorption sites. The degreasing–oxidation process removed lignin and hemicellulose, exposing cellulose surfaces rich in -OH. TA and Fe 3+ further introduced polar and coordination-active sites. Structural characterization showed that lignin removal triggered hydrogen‑bond rearrangement accompanied by pore contraction, which critically governed the subsequent adsorption behavior. These interfacial changes strongly affected adsorption behavior. Raw camphor showed almost no adsorption toward methylene blue because of the inaccessible functional groups. Fe-modified samples displayed limited adsorption due to site occupation by coordination. Oxidized camphor exhibited improved adsorption because more −OH and −COOH groups were exposed. TA modification alone produced only slight enhancement because of pore restriction and hydrogen-bond competition. In contrast, TA/Fe-modified oxidized camphor achieved the highest adsorption capacity of 312.07 mg/g, higher than oxidized camphor (164.09 mg/g). The improvement mainly resulted from the synergistic effect of exposed -OH, -COOH, and partially coordinated Fe 3+ sites. The material also maintained more than 80% of its initial adsorption capacity after five cycles. Overall, this work shows that adsorption enhancement mainly comes from interfacial reconstruction rather than pore development, providing a simple route for preparing biomass-based functional adsorbents.

Metallized ceramic substrates are essential for power electronics, offering superior thermal and electrical conductivity. However, traditional metallization techniques, such as thick printed copper (TPC), face significant challenges, including weak bonding strength, high sintering temperatures, and complications associated with glass frit, which ultimately compromise device reliability and performance. To address these issues, this study presents an efficient method for fabricating high-performance copper (Cu) films on Al 2 O 3 ceramic substrates using low-temperature, pressureless sintering. By incorporating a magnetron-sputtered copper interlayer combined with printed copper paste, we eliminate the need for glass frit, a conventional component that often introduces defects. Through careful optimization of copper powder synthesis and paste formulation, we achieved dense, low-porosity Cu films sintered at just 300°C, which demonstrate exceptional electrical conductivity (1.7 × 10 7 S m −1 ) and shear strength (31.5 MPa). The sputtered copper interlayer significantly enhances the adhesion between the copper film and the ceramic substrate, minimizing delamination and improving mechanical integrity when compared to traditional sintering methods. This approach addresses key challenges in power device packaging, providing a cost-effective, reliable solution for low-temperature, high-performance interconnections. The results have wide-reaching implications for advancing electronic packaging, especially in power electronics, by enabling durable, efficient, and scalable manufacturing processes.

A strategy for plasma-coupled O v -rich catalytic hydrogen production is proposed. • The catalyst shows high activity and universality for hydrogen production. • Synergistic cascade from plasma dissociation to catalytic surface reforming. • The key mechanism of “hydrogen promotion and anti-coking” were revealed. Hydrogen production from plastics contributes to the circular economy by enabling both waste valorisation and green energy generation. Integrated pyrolysis-plasma catalytic technology offers notable advantages in improving hydrogen production, but it still faces challenges such as catalyst coking and limited understanding of the reaction mechanisms. This study proposes a water vapor plasma-coupled oxygen vacancy-rich (O v -rich) catalytic strategy to systematically investigate the improved hydrogen production from plastics over an anti-coking catalyst. The results show that the O v -rich catalyst exhibits outstanding hydrogen production activity, strong synergistic effect, and universality in the non-thermal plasma catalytic (NTP-C) reforming reaction of mixed model compounds in plastic pyrolysis oil. Crucially, its practical effectiveness was successfully validated in the NTP-C reforming of polyethylene (PE)/polypropylene (PP) pyrolysis oils. Moreover, the O v -rich catalysts significantly inhibited coking and maintained good stability for 1800 min in a multi-component mixed system. The mechanisms of hydrogen production and coking inhibition were revealed via Density Functional Theory (DFT) calculations, in situ plasma-coupled Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS), and Optical Emission Spectroscopy (OES). A synergistic reaction pathway, coupling plasma gas-phase dissociation with catalytic surface reforming, was identified as a key mechanism for enhancing hydrogen yield in plasma-catalytic systems. The study offers valuable insights for advancing plasma-assisted hydrogen production technologies. Download: Download high-res image (150KB) Download: Download full-size image

In this study, chicken was used as the base material, and a combination of fermentation regulation and whole egg incorporation was applied to systematically investigate the effects of protein degradation degree and whole egg synergism on the quality of chicken mince gels. First, chicken mince models with different degrees of protein degradation were constructed by controlling fermentation time. The degradation characteristics were evaluated by measuring pH, trichloroacetic acid (TCA)-soluble peptides, total volatile basic nitrogen (TVB-N), and SDS-PAGE, together with sensory evaluation to assess structural and flavor changes. Subsequently, composite gels were prepared by adding 10%, 20%, and 30% whole egg to the fermented chicken mince. The texture profile analysis (TPA), water-holding capacity (WHC), and cooking loss were systematically determined. The results showed that moderate protein degradation reduced gel hardness while generating a protein matrix suitable for subsequent gel modification. Whole egg incorporation subsequently improved gel texture, enhanced water-holding capacity, and reduced cooking loss, with the 30% addition level exhibiting the best overall quality. The addition of whole egg further optimized the gel network structure, increased gel strength, and reduced cooking loss, with the 30% addition level exhibiting the best overall quality. Finally, the swallowing properties were evaluated based on the International Dysphagia Diet Standardization Initiative (IDDSI). The results indicated that the optimized composite gels met the dietary requirements for individuals with dysphagia. Overall, this study elucidates the synergistic mechanism of protein degradation and whole egg incorporation in regulating the quality of chicken mince gels, providing a theoretical basis and technical support for the development of high-protein, animal-based gel foods tailored for dysphagia patients and the elderly population.

Phase control of alloy nanomaterials can modulate their atomic/electronic structures towards various electrocatalytic applications. However, the controlled synthesis of high-entropy nanoalloys (HENAs) with unconventional phase remains challenging. Here we report the one-pot synthesis of RhCuNiInSb HENAs with the unconventional 2H phase through regulating the nucleation/growth kinetics. Compared with the face-centred cubic phase counterpart, 2H RhCuNiInSb HENAs exhibit superior electrocatalytic nitrate reduction performance at low nitrate concentration. Ex/in situ studies reveal the accelerated deoxygenation/hydrogenation kinetics and distinct reaction pathway. Theoretical calculations demonstrate the electronic optimizations induced by the face-centred-cubic-to-2H phase transition, where the electronic redistribution and p – d elemental interactions improve the surface electroactivity. When operated in flow cell, 0.5 l of simulated wastewater can be efficiently converted into the value-added ammonia-derived product within 10 h. With a 20-h electrolysis, the NO 3 − -N concentration in real industrial and agricultural wastewater can be both reduced above the World Health Organization standard for drinking water.

A dual-interface engineering strategy is proposed to exploit the anticorrosion potential of cerium oxide fillers by combining an oxygen-vacancy-rich porous core with a fluorinated superhydrophobic shell. Porous CeO 2 (P-CeO 2 ) is synthesized via a P123-templated hydrothermal process and then functionalized with perfluoroalkyl silane to form fluorinated porous CeO 2 (F-CeO 2 ). Conventional CeO 2 , P-CeO 2 , and F-CeO 2 are dispersed into a fluorocarbon resin to prepare composite coatings at different filler loadings. Characterization confirms that fluorination preserves the mesoporous fluorite framework while converting the surface from hydrophilic to superhydrophobic (water contact angle 164°) and promoting an oxygen‑vacancy-enriched surface character. The fluorinated porous particles also show improved colloidal stability in xylene, enabling homogeneous dispersion in the coating matrix. Electrochemical tests in 3.5 wt.% NaCl identify 1.0 wt.% F-CeO 2 as the optimal formulation: The corrosion current density decreases from 5.226 μA·cm −2 for the neat resin to 0.00353 μA·cm −2 , corresponding to 99.93% inhibition efficiency and exceeding coatings with conventional CeO 2 (91.50%) or P-CeO 2 (94.03%). Electrochemical impedance spectroscopy shows that this coating maintains near-ideal capacitive behavior over 21 days of immersion, with coating and double-layer constant-phase exponents remaining ~ 0.92-1.00; a diffusion-controlled Warburg element emerges only after prolonged exposure, indicating delayed electrolyte access to the metal/coating interface. AFM and XRD support a synergistic mechanism in which the fluorinated shell suppresses wetting and ion ingress, while the oxygen-vacancy-rich porous core promotes active passivation. Here, the “dual-functional” design refers to the integration of a superhydrophobic physical barrier provided by the fluorinated shell and a chemical passivation effect induced by oxygen vacancies in the CeO 2 core, which operate synergistically to enhance corrosion resistance. This dual-interface design makes F-CeO 2 an efficient bifunctional filler for durable anticorrosion fluorocarbon coatings. Overall, the approach improves barrier integrity, durability under chloride attack.

A thiolated graphene/AuNPs nanointerface was constructed to enhance electron transfer. • An electropolymerized EMIP layer enabled selective epitope-based recognition of AFP. • A sensitive epitope-imprinted electrochemical biosensor was developed for AFP analysis. • The sensor exhibited a wide linear range (0.001–100.0 ng mL −1 ) and a low LOD of 0.069 pg mL −1 . • The biosensor enabled reliable AFP determination in spiked human plasma samples. Alpha-fetoprotein (AFP) is a clinically important serum biomarker for the early diagnosis of hepatocellular carcinoma. However, conventional AFP detection methods often suffer from limited sensitivity, selectivity and operational complexity. In this work, an electrochemical biosensor based on an epitope molecularly imprinted polymer (EMIP) was developed for the sensitive and selective determination of AFP. The sensing interface was constructed by electropolymerization of o -phenylenediamine ( o -PD) on a gold electrode sequentially modified with thiolated graphene (G–SH) and gold nanoparticles (AuNPs), using the AFP C-terminal dodecapeptide (KLISKTRAALGV) as the epitope template. The excellent analytical performance of the biosensor can be attributed to the synergistic integration of the EMIP recognition layer, G–SH, and AuNPs, which provide highly selective molecular recognition, an enlarged electroactive surface area and accelerated interfacial electron transfer. Under the optimized conditions, the proposed biosensor exhibited a wide linear range of 0.001–100.0 ng mL −1 , and a low detection limit of 0.069 pg mL −1 , together with excellent selectivity against NMP22, bovine serum albumin (BSA), human serum albumin (HSA), and neuron-specific enolase (NSE), good reproducibility, and satisfactory storage stability. Satisfactory recoveries obtained in spiked human plasma samples demonstrated its potential applicability for AFP determination in complex biological matrices. This work provides a sensitive and robust platform for AFP determination and highlights the potential of epitope-imprinted electrochemical biosensors for hepatocellular carcinoma screening and clinical biomarker monitoring. An epitope-imprinted electrochemical biosensor integrating an electropolymerized EMIP film with a thiolated graphene/AuNPs nanointerface was developed for AFP detection. The biosensor combines highly selective molecular recognition with enhanced electron transfer, achieving a 0.069 pg mL −1 detection limit and successful analysis of spiked human plasma samples.

Rapid and reliable detection of foodborne pathogens is essential for ensuring food safety, yet achieving high selectivity and sensitivity in complex matrices remains challenging. Herein, we report a sensitive and selective electrochemical sensing platform integrating a bacteria-imprinted polymer (BIP) capture interface with concanavalin A-functionalized Fe 3 O 4 (Fe 3 O 4 -ConA) for the detection of Escherichia coli O157:H7 ( E. coli O157:H7). The BIP film was electropolymerized in situ on glassy carbon electrode to generate recognition sites for efficient capture of E. coli O157:H7. Subsequently, Fe 3 O 4 -ConA bound to surface glycans on the captured bacteria through lectin-glycan interactions, forming a sandwich-like sensing interface. The anchored Fe 3 O 4 nanozyme catalyzed the H 2 O 2 -mediated oxidation of o -phenylenediamine, producing amplified electrochemical signals for bacterial quantification. Benefiting from the combination of imprinting-based recognition and catalytic amplification, the sensor achieved an ultrasensitive detection limit of 2.8 CFU mL −1 and a linear range from 10 1 to 10 5 CFU mL −1 . Recoveries of 93.29–113.62% were obtained in spiked milk, fish, and juice samples, with reliable detection down to 10 CFU mL −1 in complex food matrices. This work provides an effective strategy for constructing nanozyme-amplified electrochemical sensors for sensitive and selective monitoring of foodborne pathogens.

Acrylamide (AA) is a common contaminant in foods processed at high temperatures and has attracted significant attention due to its potential neurotoxicity and carcinogenicity. Therefore, the development of a highly sensitive, highly selective sensing technology suitable for on-site detection is of great importance for ensuring food safety. In this study, an aptamer (Apt)-based capacitive AA sensor was developed based on the alternating current electrokinetics (ACEK) effect. The sensor utilizes an aptamer as the biomimetic recognition element, which can specifically recognize AA, thereby enabling quantitative detection. Additionally, a detachable detection fixture and data acquisition system were designed to enhance the detection stability and convenience of sensor. Within the linear range of 1 nmol/L to 10 µmol/L, the sensor response (dC/dt) exhibited a good linear relationship with AA concentration, with a detection limit as low as 0.4235 nmol/L. The sensor exhibits good selectivity toward structural analogs of AA, with a recovery relative standard deviations (RSDs) of less than 5.42% in spiked coffee samples. This portable detection system provides a sensitive and user-friendly tool for the analysis of acrylamide in food and holds great potential for application in food safety.
