        <description><![CDATA[IntroductionTo enhance the inherent shear resistance of in-service highway subgrade soils and effectively improve subgrade safety resilience under short-term traffic closure conditions, this study proposes a technical scheme of installing actively-compacted micro-expansive piles.MethodsUtilizing field-measured parameters of the subgrade soils and micro-expansive piles materials, a finite element model was established to analyze the effects of radial stresses (10 kPa, 50 kPa, 100 kPa) induced by various expansion rates on the stress distribution of the subgrade, as well as the influence of different diameter-to-spacing ratios (0.2, 0.4, 0.6) on the overall shear resistance of the subgrade.ResultsThe results indicate that when the diameter-to-spacing ratio is 0.2, the radial stress attenuates by 89.53%–95.82% at the midpoint between two piles, indicating a limited effective stress transmission distance. Increasing the diameter-to-spacing ratio to 0.6 reduces the attenuation to 24.05%–25.15%, resulting in a more uniform stress distribution. Under a diameter-to-spacing ratio of 0.6 and a radial stress of 100 kPa, the maximum principal stress at the limit equilibrium state of the subgrade soils within the pile-influenced depth (0–5 m) is enhanced by an average of 60.5%.DiscussionThis study demonstrates that appropriately configured radial stress and diameter-to-spacing ratios can significantly enhance the subgrade’s resistance to shear failure, providing a scientifically effective approach for improving the safety resilience of in-service highway subgrades.]]></description>

        <description><![CDATA[To mitigate the environmental impact associated with the high cement consumption in conventional 3D printable concrete (3DPC) and to enhance the intelligent thermal regulation capacity of modern buildings in complex environments, a novel 3D printable phase-change concrete incorporating industrial solid wastes was developed in this study. Through comprehensive assessments of fluidity, extrudability, and buildability, the critical workability control parameters satisfying the requirements of continuous 3D printing were determined. Subsequently, the response surface methodology based on a Box-Behnken design was employed to analyze the individual and interactive effects of silica fume content, microencapsulated phase-change materials dosage, and water-to-binder (W/B) ratio on the 28-day compressive strength of the 3D printed specimens. The analysis of variance results indicated that the significance of these three factors on compressive strength followed a descending order of W/B ratio > mPCMs dosage > silica fume content. Furthermore, all factors exhibited a highly significant non-linear quadratic effect, characterized by an initial increase followed by a subsequent decrease. A single-response optimization algorithm was utilized to determine the optimal mixture design, targeting the maximization of mechanical properties under a fixed printability constraint: a W/B ratio of 0.265, a silica fume content of 7.22%, and an mPCMs dosage of 2.72%. Experimental validation demonstrated that the measured 28-day compressive strength of the optimal mixture was 46.54 MPa, yielding a relative error of only 6.26% compared to the predicted value. This confirmed the high accuracy and reliability of the established quadratic regression prediction model. This study provides a reliable material foundation and scientific basis for the development of highly efficient 3D printed concrete components with integrated thermal management functionalities.]]></description>

        <description><![CDATA[To clarify the influence of pulverized coal gradation on the cyclic damage behavior of grouted consolidated bodies, this study used cement-pulverized coal composites as the research object. Three pulverized coal contents (10%, 20%, and 30%) and three pulverized coal particle radii (300 μm, 75 μm, and 28 μm) were designed, and cyclic loading-unloading tests, damping-energy separation analysis, and PFC numerical simulations were performed. Based on an equivalent single-degree-of-freedom model, a damping-energy calculation method was established, and a modified damage factor considering the damping effect was proposed to distinguish damping energy consumption from damage energy consumption within the hysteretic dissipated energy. The results show that, when the pulverized coal particle radius decreases from 300 μm to 28 μm, the specimen density increases by 9.94%–12.24%, whereas slurry fluidity decreases by 28.26%–82.93%. This indicates that fine pulverized coal can improve the compactness of the consolidated body but reduces slurry workability. The uniaxial compressive strengths of specimens with different gradations range from 10.17 to 46.04 MPa, suggesting that 28 μm pulverized coal is beneficial for enhancing the load-bearing capacity of the specimen, whereas a pulverized coal content of 30% weakens the continuous cemented structure of the cement matrix. During cyclic loading, the total mechanical energy density, elastic energy density, and damping energy density all increase nonlinearly with the number of cycles. The modified damage factor is lower than the conventional energy-based damage factor, indicating that ignoring the damping effect overestimates the actual damage degree of the material. PFC moment-tensor analysis shows that specimen failure is dominated by tensile cracks, with tensile cracks accounting for 28.00%–39.00%, whereas shear cracks and compression-closure cracks account for 21.00%–30.00% and 21.00%–28.00%, respectively. The results indicate that pulverized coal gradation controls the cyclic damage evolution of grouted consolidated bodies by altering particle packing, interfacial friction, damping dissipation, and crack propagation. These findings provide a quantitative basis for evaluating the vibration resistance of coal-pillar grouted reinforcement under cyclic mining-induced loading.]]></description>

        <description><![CDATA[To address the dual challenges that conventional asphalt pavements are prone to softening and rutting under elevated summer temperatures while also exacerbating the urban heat island effect, this study proposed a composite modification strategy for asphalt mixtures using purified diatomite (PD) and titanium dioxide (TiO2). The effects of PD dosage on the fundamental properties of the asphalt binder and the thermal conductivity of the mixture were systematically investigated. The pavement performance, thermal-insulation capacity, and resistance to light-induced high-temperature softening of PD–TiO2 composite-modified asphalt mixtures were comprehensively evaluated, and the underlying synergistic mechanism was elucidated. The results showed that the penetration and ductility of asphalt decreased monotonically with increasing PD content, whereas the softening point and rotational viscosity increased monotonically, with an apparent performance inflection occurring at a PD dosage of approximately 15%. PD–TiO2 composite modification significantly enhanced the high-temperature rutting resistance, moisture stability, and light-induced softening resistance of the asphalt mixture. In particular, compared with the control group, the P2T3 formulation (15% PD + 3.5% TiO2) exhibited increases of 74.9% and 266.7% in Marshall stability and dynamic stability, respectively. PD and TiO2 synergistically established a dual thermal-barrier mechanism, ranging from radiative reflection to conductive heat inhibition, enabling the P2T3 group to achieve an average temperature reduction of up to 5.9 °C. Based on the overall performance evaluation, the optimum dosages of PD and TiO2 were determined to be 15% and 3.5%, respectively. These findings provide a theoretical basis and technical support for the material design of high-performance thermally insulating asphalt pavements.]]></description>

        <description><![CDATA[Sustainable manufacturing has emerged as a critical paradigm for the future of industry, integrating environmental stewardship with operational excellence. Against this backdrop, the rapid evolution of machine learning and deep learning is catalyzing the intelligent transformation of hot rolling production—a sector with substantial energy and material demands. This paper focuses on the core processes of hot rolling and provides a systematic review of machine learning applications for predicting and controlling key quality indicators, including crown, thickness, and width. By fusing multi-source process data with advanced intelligent algorithms, we construct a predictive quality framework tailored to the hot rolling environment, enabling precise monitoring and real-time adjustment of crown deviations, thickness variability, and width fluctuations. Empirical results demonstrate that machine learning approaches effectively capture complex, nonlinear interdependencies between process parameters and product quality, significantly enhancing both production stability and consistency. In addition, we propose a multimodal perception-based framework for early warning and dynamic optimization, facilitating coordinated, real-time parameter adjustments. This integrated strategy not only offers a viable technical pathway for smart manufacturing but also contributes practical insights toward more sustainable and resource-efficient hot rolling operations.]]></description>

        <description><![CDATA[Dredged Yellow River sediment (DYRS) is widespread in nature and generally features low water holding capacity due to poor grain grading and lack of clay minerals. Low water holding capacity can impede its application in interdisciplinary engineering and ecological scenarios such as ecological slope substrate and ecological remediation of mining area. This study investigates the role of carbon sequestration methods in the water holding capacity and microscopic mechanism of DYRS. DYRS is improved by two types of carbon sequestration methods, i.e., biochar additive and CO2 curing with the agent of reactive MgO (rMgO). The results show that the biochar additive and CO2 curing lead to an increase rate of water holding capacity by 49.5% and 180%, respectively. The biochar-treated DYRS features an optimum water holding capacity of DYRS, corresponding to an optimum particle size fraction of biochar. However, such an optimum water holding capacity of DYRS does not hold for the case of CO2 curing. The increasing dose of rMgO and CO2 curing duration are both favorable for improving the water holding capacity of DYRS, attributed to the binding products of chemical reaction. The performance of water holding capacity in treated DYRS is closely associated with altered pore structures by carbon sequestration methods. Biochar leads to a change of trimodal pore structure in untreated DYRS to bimodal pore structure in treated DYRS. However, CO2 curing reshapes the trimodal pore structure and facilitates the formation of new smaller pore sizes in treated DYRS. The research findings are fundamental for the future application of dredged river soils and carbon sequestration methods in engineering practice.]]></description>

        <description><![CDATA[Steel slag (SS), coal gangue (CG), and construction waste (CW) were investigated as partial replacements in cement-stabilized aggregate mixtures for highway semi-rigid bases, with incorporation rates ranging from 0% to 80%. Performance assessments included unconfined compressive strength, flexural strength, drying shrinkage, and freeze-thaw resistance, followed by optimal material selection using a comprehensive fuzzy algorithm. Results indicated that SS synergistically enhanced overall performance. Active components within SS induced micro-expansion, reducing drying shrinkage by 29.5%–40.0%. Furthermore, continued hydration increased 360-day compressive strength by 16.0%–36.2%, flexural strength by 42.1%–52.9%, and the freeze-thaw strength ratio by 17.3%. Conversely, CW content exceeding 60% increased drying shrinkage by 10.8% due to fine aggregate hydration, yielding only marginal compressive strength gains (4.4%–7.3%) at 360 days. High CG levels (>40%) caused significant degradation in mechanical and durability properties due to layer structure disintegration; compressive strength decreased by 30.9%–46.9%, flexural strength fell by 40%, and freeze-thaw resistance declined by over 10%. Drying shrinkage for all mixtures conformed to the EXPASSOC model (R2 > 0.99), exhibiting a three-stage pattern where 85% of shrinkage occurred within 60 days, followed by stabilization after 100 days. A derived cracking resistance index confirmed that SS dosages of >40% provided optimal anti-cracking performance. Fuzzy comprehensive algorithm analysis identified SS (40%–80% incorporation) as the optimal material choice. Consequently, CG requires strict limitation to ≤40%, whereas CW is permissible at ≤ 40% (excluding fine aggregates). These findings provide theoretical support for the classified resource utilization of multi-source solid wastes in highway base courses.]]></description>

        <description><![CDATA[In this work, InSnZnO (ITZO) thin films with different structural phases were obtained via Al-induced microstructure regularization (AIMR) method. The thin-film transistor (TFT) with amorphous front-channel and polycrystalline back-channel exhibits remarkable field-effect mobility (μFE) boosted to 115.2 cm2/Vs which is about twice that of the TFT with fully-crystallized channel. It is found that the partially-crystallized ITZO shows a denser microstructure with less oxygen vacancies (VO) in the front-channel region compared to the fully-crystallized one. Other electrical properties as well as the negative-bias-stress stability are also improved. TCAD simulations were performed to investigate the defect states in the channel, providing supportive evidence for the experimental results. Keeping the amorphous state and promoting its microstructure ordering to the utmost is a promising strategy to achieve high-mobility oxide TFTs.]]></description>

        <description><![CDATA[BackgroundPhotocatalysis is proposed as a sustainable, energy-saving method for environmental remediation using solar energy. Graphitic carbon nitride (g- C3N4) is a promising visible-light-responsive photocatalyst, but its application is limited by fast charge recombination and difficult separation in aqueous solutions.ObjectiveTo develop a reusable, 3D porous photocatalyst by modifying g- C3N4 aerogel foam with bimetallic Cu and Mn nanoparticles for simultaneous photocatalytic degradation of organic pollutants and antibacterial disinfection.Methods3D g- C3N4 aerogel foam was synthesized and modified with Cu and Mn nanoparticles via hydrothermal assembly and in situ photoreduction. The materials were characterized by SEM, FTIR, and XRD. Photocatalytic activity was evaluated by degradation of methyl orange under visible light. Antibacterial performance was tested against E. coli and B. subtilis. Active species were identified by trapping experiments. Cycling tests were performed to assess stability and reusability.ResultsThe 3D porous structure improved mass transfer, enhanced light harvesting via multiple scattering, and facilitated catalyst recovery. Characterization confirmed formation of the porous framework and successful incorporation of Cu and Mn. The optimized Cu-Mn/g- C3N4 composite achieved 98.5% degradation of methyl orange within 60 min, with an apparent pseudo-first-order rate constant of 0.065 min-1, which is ∼4.2 times higher than pristine g- C3N4. The material also showed >99.99% inactivation of E. coli and B. subtilis under visible light. Photocatalytic cycling showed high stability, while antibacterial cycling showed reduced stability due to surface roughening. Active species trapping indicated O2- and H+ as the main reactive species.ConclusionThis study presents an effective strategy for developing efficient, reusable, and multifunctional 3D Cu-Mn/g-C3N4 aerogel photocatalysts. The material shows strong potential for applications in water purification and disinfection due to enhanced charge separation, increased active sites, and dual photocatalytic antibacterial functionality.]]></description>

        <description><![CDATA[BackgroundH-shaped joints, which consist of tensile and shear parts, are common in layered rocks and substantially affect rock failure and instability.ObjectiveTo explore the mechanical performances of the H-jointed sandstone under different loading conditions.MethodsUniaxial and confined compressive tests were carried out on H-jointed sandstone samples. The samples’ stress-strain responses, failure modes, AE activities, and strength were analyzed.ResultsThe results show that the stress-strain curve has four phases: crack closing, elastic phase, elastic-plastic phase, and residual stages. The failure patterns of the H-jointed samples change from tension to shear as the joint dip angle increases. Tensile failure is dominant at lower inclination angles, whereas shear slip failure occurs along the joint surfaces at higher angles. Sliding along the joint surfaces with tensile cracking is observed at moderate angles. The joint roughness coefficient (JRC) significantly influences the samples’ mechanical behavior. A modified Hoek-Brown criterion that considers the joint dip angle and JRC is suggested for evaluating the strength of H-jointed rock samples under compression.ConclusionsThis study provides a better understanding of the mechanical performance of H-jointed sandstone and a method to evaluate the strength.]]></description>

        <description><![CDATA[Pavement raveling is characterized by the progressive loss of surface aggregates and poses significant challenges to road durability and safety. The early detection and monitoring of this disease are crucial for implementing timely maintenance interventions. This study adopts a transfer learning approach for automated raveling detection in asphalt pavements. A comprehensive in situ raveling dataset comprising 530 images and 215 normal pavement images was collected using the LS-40 portable three-dimensional surface analyzer. Following histogram equalization for noise reduction, the dataset was augmented to 1600 images through mirroring and rotation techniques. The transfer learning was fine-tuned on four base convolutional neural network structures: the VGG16, the EfficientNet-B0, the InceptionV3, and the RegNet. The models were trained using standardized parameters, including an input size of 224 × 224, a batch size of 32, and 200 epochs, with regularization and dropout techniques applied to mitigate overfitting. A comparative analysis of optimization algorithms showed that RMSprop outperformed both SGD and Adam for this specific task. Transfer learning significantly enhanced the performance of all models, with the EfficientNet-B0 achieving outstanding results—achieving both high accuracy (99.7%) and low energy consumption in raveling detection. The selected models achieved AUC values exceeding 0.95, while the transfer learning significantly reduced training time and enhanced feature extraction capabilities, as confirmed through convolutional layer visualization. These findings establish the EfficientNet-B0 as the optimal structure for practical deployment in automated pavement inspection systems, providing a robust foundation for intelligent infrastructure maintenance strategies.]]></description>

        <description><![CDATA[Per- and polyfluoroalkyl substances (PFAS) represent a particularly persistent subclass of emerging contaminants whose structural diversity, extreme stability, and complex physicochemical behavior pose significant challenges for adsorption-based water treatment. Polymeric magnetic adsorbents, which integrate the tunable chemical functionality of polymer networks with the rapid separability and interfacial activity of magnetic nanoparticles, have emerged as promising hybrid materials for PFAS remediation. This mini review provides a concise mechanistic overview of the dominant molecular interactions governing PFAS uptake on polymer–magnetic systems, including hydrophobic and fluorophilic interactions, hydrogen bonding, surface complexation, pH-dependent electrostatic forces, and the synergistic effects of magnetic nanoparticle incorporation on adsorption performance. Particular emphasis is placed on how PFAS molecular structure, polymer chemistry, and nanoparticle incorporation collectively influence adsorption performance, kinetics, and selectivity, especially in the presence of competing ions and dissolved organic matter commonly found in natural waters. Finally, key design principles are summarized to guide the development of next-generation polymeric magnetic adsorbents. This mechanistic framework aims to support material optimization and promote more efficient removal of diverse PFAS across complex water matrices.]]></description>

        <description><![CDATA[The 304L stainless steel is widely used in nuclear power plant system medium transmission due to its good economic benefits and excellent performance. However, during service, it faces the risk of stress corrosion cracking (SCC). This paper uses characterization testing methods such as OM, EBSD, hardness testing, and SSRT to study the influence of light rolling deformation (10%) on the microstructure, mechanical properties, and stress corrosion performance of nuclear-grade 304L stainless steel. After 10% rolling deformation treatment, the dislocation density and small-angle grain boundaries increase significantly, and compressive stress/strain residuals exist within the material. The hardness of the material increases from 135HV to 198HV, and the SSRT test limit tensile strength in the simulated environment of primary circuit coolant is increased from 455 MPa to 528 MPa. After 10% rolling treatment of 304L stainless steel, it has reduced SCC susceptibility under the tested conditions.]]></description>

        <description><![CDATA[BackgroundDiabetic foot ulcers (DFUs) represent a severe global health challenge, often characterized by persistent oxidative stress and a stalled inflammatory phase that prevents normal wound healing. Chronic accumulation of reactive oxygen species (ROS) leads to an inflammatory lock where macrophages remain in a pro-inflammatory M1 phenotype. This study aims to develop kiwifruit-derived plant extracellular vesicles (K-PEVs) as a sustainable, cell-free therapeutic platform to remodel the diabetic wound microenvironment and accelerate regeneration.MethodsK-PEVs were isolated from fresh kiwifruit juice using differential centrifugation combined with ultracentrifugation. The vesicles were characterized via transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and dynamic light scattering (DLS). In vitro, the effects of K-PEVs on HaCaT cell migration, NIH3T3 cell viability, and ROS scavenging in Raw264.7 macrophages were evaluated. In vivo, a full-thickness foot wound model in STZ-induced diabetic rats was established to assess the healing efficacy of low-dose (5 μg/mL) and high-dose (20 μg/mL) K-PEV treatments. Histological (H&E, Masson’s trichrome) and immunofluorescence (CD86) analyses were performed to evaluate tissue remodeling and macrophage polarization.ResultsK-PEVs exhibited a typical cup-shaped morphology with an average diameter of approximately 155 nm and high colloidal stability. In vitro assays demonstrated that K-PEVs dose-dependently promoted HaCaT migration and NIH3T3 viability while significantly scavenging intracellular ROS in Raw264.7 cells. In vivo, K-PEV treatment significantly accelerated wound closure, enhanced re-epithelialization, and increased collagen deposition. Notably, immunofluorescence staining revealed a marked reduction in CD86 expression in K-PEV-treated wounds, indicating a successful transition from the M1 pro-inflammatory phenotype to a pro-reparative microenvironment.ConclusionOur findings demonstrate that K-PEVs effectively promote diabetic wound healing by mitigating oxidative stress, resolving chronic inflammation through the modulation of macrophage polarization, and stimulating essential cellular activities. K-PEVs represent a promising green nanomedicine strategy for the clinical management of chronic diabetic ulcers.]]></description>

        <description><![CDATA[Road icing in winter very easily poses a threat to driving safety. The application of road snow melting agent can improve this problem, but current road snow melting agents pose a threat to the environment and road infrastructure. The purpose of this study is to prepare a low-carbon, environmentally friendly road snow melting agent and explore its performance. In this study, low-carbon salts were selected as raw materials, and the components of low-carbon environmentally friendly snow melting agents were optimized by simplex center-of-gravity design. Then, the indoor and outdoor ice-melting performance and environmental protection performance of low-carbon environmentally friendly road snow melting agent were studied. Finally, the low-carbon environmentally friendly snow melting agent was incorporated into the asphalt mixture to prepare a low-carbon, environmentally friendly anti-icing asphalt mixture, and its anti-icing performance was evaluated. The results showed that a large concentration of low-carbon environmentally friendly road snow melting agent had an inhibitory effect on the corrosion of carbon steel, and the effect of such an agent on plant seeds was smaller than that of traditional chlorine salt road snow melting agent. The low-carbon, environmentally friendly anti-condensation ice asphalt mixture showed good anti-condensation ice performance; in particular, the anti-condensation ice asphalt mixture prepared by external mixing method shows more obvious anti-condensation ice performance. The optimum ratio of low-carbon, environmentally friendly road snow melting agent is 23.9% potassium acetate, 27.4% sodium acetate, and 48.7% ammonium acetate.]]></description>

        <description><![CDATA[Interfacial insulation degradation remains a critical barrier to the reliability of wide-bandgap power electronic packaging subjected to high-frequency pulse voltages and elevated temperatures. This study systematically investigates the electrical treeing behavior at the silicone gel/ceramic substrate interface. It is found that the interfacial electrical treeing exhibits a characteristic three-stage evolutionary process, transitioning from initial sparse dendritic initiation to the rapid expansion of complex reticular cracks, and finally into a stagnation stage where growth rates approach zero. The final tree length follows a linear positive correlation with the pulse voltage amplitude. Besides, the electrical tree length increases significantly with rising frequency in the low-frequency range, while no obvious change in length occurs with further increase in frequency over 5 kHz. On the other hand, the higher the temperature is, the greater the growth rate of electrical trees in the rapid growth stage, and the length of electrical trees increases with the increase in temperature. These findings provide fundamental insights into the interfacial failure mechanisms of elastomeric encapsulants and offer a theoretical framework for designing high-performance insulation systems for next-generation SiC power devices.]]></description>

        <description><![CDATA[This study reports the experimental demonstration of a GaN-based resonant cavity microLED towards future optical interconnect applications. GaN-based microLEDs can enable high bandwidth and low power consumption optical interconnect applications due to GaN’s excellent material properties. Meta-microLED is fabricated by positioning a GaN LED inside a cavity sandwiched between a nanoporous GaN distributed Bragg reflector mirror and a nanopatterned TiO2 metasurface mirror. With the presence of the resonant cavity, the divergence angle of the meta-microLED has been successfully reduced by 25° for the 100 µm devices and 29° for the 5 µm devices, and the emission linewidth is also reduced by 5.5 nm. Applying the mirrors as Fabry-Pérot resonators, the meta-microLED also demonstrates a more stable light emission with increasing device temperature up to 250°C, where the reference LED shows a wavelength shift of 13 nm and the meta-microLED only shows a shift of 4 nm. These results demonstrate meta-microLED’s great potential towards future optical interconnect applications.]]></description>

        <description><![CDATA[The widespread commercialization of proton exchange membrane fuel cells (PEMFCs) relies fundamentally on developing cost-effective, highly active Pt-based cathode electrocatalysts. Beyond conventional intrinsic structural optimization of Pt, current design strategies increasingly emphasize the coupled regulation of active-site composition, catalyst-support interaction, and interfacial microenvironment. While traditional modification strategies predominantly focus on the intrinsic structural optimization of Pt to enhance utilization efficiency, the frontier of electrocatalyst design has evolved. Current paradigms transcend the isolated structural engineering of Pt, emphasizing instead the synergistic interplay within the entire catalytic architecture—specifically the holistic optimization of reaction interfaces, supporting substrates, and integrated active sites. Herein, a comprehensive review of the structure–activity relationships in advanced Pt-based electrocatalysts is presented, with a central focus on their underlying catalytic mechanisms. Representative strategies including strain/ligand regulation, ordered intermetallics, core-shell structures, single-atom catalysts/alloys, high-entropy alloys, light-element doping, support engineering, and surface microenvironment control are systematically discussed. Distinct from conventional reviews that primarily catalog morphological characteristics, this work uniquely delves into the fundamental physicochemical origins governing catalytic efficacy. In addition, the gap between rotating disk electrode evaluation and membrane electrode assembly performance is briefly highlighted to emphasize practical device relevance. By systematically categorizing these advanced structural synergies, this review elucidates the intrinsic reasons behind the effectiveness of state-of-the-art designs, providing critical mechanistic insights and strategic guidelines for the rational construction of next-generation high-performance PEMFC electrocatalysts.]]></description>
