Ultrasonic treatment has shown potential for reducing the viscosity of heavy oils and asphaltic materials; however, the underlying rejuvenation mechanism of aged asphalt at the molecular scale remains insufficiently understood. In this study, the interaction between ultrasonic cavitation and aged asphalt is investigated from an energy-based and molecular-level perspective using molecular dynamics (MD) simulations combined with cavitation energy analysis. A representative aged asphalt model consisting of twelve molecular species was constructed based on the SARA fraction composition of JingBo 70# asphalt, incorporating oxidation-induced functional groups (C<img>O and S<img>O). Intermolecular cohesion within the aged asphalt system was quantified, revealing that π-π stacking and hydrogen bonding dominate the electrostatic interaction energy that stabilizes molecular aggregates. An order-of-magnitude comparison indicates that the energy released during the collapse of a single ultrasonic cavitation bubble is sufficient to overcome the characteristic intermolecular cohesive energy within the affected volume. To examine the molecular response under ultrasonic excitation, a time-dependent ultrasonic-like external force was introduced in MD simulations at 20 kHz and 453 K. The results show that ultrasonic excitation induces periodic energy and temperature oscillations and leads to rapid bond scission at the early stage of loading. Bond rupture occurs preferentially at weaker C–C and C–S single bonds, particularly at side-chain positions and C–C bonds adjacent to carbonyl groups, resulting in molecular fragmentation and reduced aggregation stability. Complementary experimental results, including viscosity measurements and SARA fraction analysis, exhibit trends consistent with the simulated molecular disruption behavior. These findings provide an energy-based and molecular-scale mechanistic interpretation of ultrasonic treatment of aged asphalt and offer theoretical support for its potential application in asphalt rejuvenation and recycling.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"126 ","pages":"Article 107765"},"PeriodicalIF":9.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146135082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces a novel method, direct ultrasonic-assisted chemical milling (UACM), as an efficient and sustainable alternative to CHM. A full-factorial design examined three ultrasonic powers (50, 150, 250 W) across acidic and alkaline etchants at three concentration levels. MRR and roughness parameters (Ra, Rz, Sa) were experimentally quantified and modeled using ANOVA-based regression, while multi-region SEM/EDS elucidated oxide disruption, pit formation, and surface evolution on Al 6061. In 10 % HCl at 250 W, UACM increased MRR by 591 % through cavitation-enhanced agitation and rapid renewal of reactive species, enabling≈85.5 % reduction in acid use. Moreover, at matched MRR, UACM yielded 15–30 % lower Sa than CHM, producing uniform microporosity beneficial for bonding and coating applications. The best acidic condition was 15 % HCl at 250 W, where MRR increased from 0.70 to 1.30 mm/m/s and produced a clean, crack-free, homogeneous surface with optimal integrity. The optimal alkaline condition was 50 % NaOH at 250 W, where MRR increased from 0.08 to 0.23 mm/m/s (≈65.2 % time reduction), and the disruption of hydrogen-bubble shielding generated a uniform and stable morphology. Key experimental challenges included maintaining thermal stability under high acoustic power, controlling bubble adhesion in alkaline media, and achieving a reproducible initial surface. Overall, UACM substantially enhances removal efficiency, improves surface integrity, and reduces chemical consumption, offering a practical pathway toward high-precision and greener manufacturing.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"126 ","pages":"Article 107753"},"PeriodicalIF":9.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146048115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that arabinose and galactose were the main monosaccharides in INP, which was identified as a pectic heteropolysaccharide with a high molecular weight (M_w = 9.26 × 10⁵ Da) and high polydispersity (PDI = 11.42). INP exhibited a compact random coil conformation and a loose, porous morphology. The incorporation of SPI effectively reduced the interfacial tension of the SPI-INP composite system, significantly enhancing the stability of the resulting nanoemulsions. The concentration of the INP-SPI mixture, the SPI/INP mass ratio, and ultrasonic conditions significantly influenced the formation of the nanoemulsions. Based on the results of single-factor experiments and response surface analysis, the optimal process parameters for nanoemulsion preparation were determined as follows: INP-SPI concentration 1.6%, SPI/INP mass ratio 2.1:1, ultrasonic power 500 W, and ultrasonic time 5.3 min. Validation experiments confirmed that under these conditions, the average droplet size of the obtained nanoemulsion was 214.10 ± 1.74 nm, which closely aligned with the model-predicted value (216.33 nm). The superior stability of the INP-SPI nanoemulsion under various pH (6.0–9.0) and salt (0–100 mM NaCl) conditions was attributed to the formation of a robust interfacial layer providing steric stabilization, as validated through droplet size analysis and environmental stress testing. This research promotes the in-depth utilization of immature nectarine resources and provides a reference for the construction of food-grade nanoemulsions.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"126 ","pages":"Article 107771"},"PeriodicalIF":9.7,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146138832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound process markedly accelerated glycation, with a 45 min sonicated sample glycation to a similar degree to that induced by traditional 3 h treatment, such that cavitation facilitates early MR pathways. Both approaches enhanced solubility and remodeled secondary structures, although in different manners: conventional heating promoted a gradual increase in β-sheet content and a decrease in α-helix content, while ultrasound induced rapid unfolding and structural reorganization. All MRPs enhanced the emulsifying properties, but the conventional sample after 3 h obtained the highest emulsifying activity index (EAI) and emulsion stability index (ESI) values. Samples treated with ultrasound showed moderate improvement, however, at considerably reduced reaction times. Dynamic light scattering (DLS) and fluorescence microscopy have also confirmed that conventionally heated MRPs form smaller and more uniform droplets. Volatile profiling indicated that conventional heating produced a broader spectrum of aldehydes, ketones, and furans associated with off-flavors, whereas ultrasound greatly reduced compounds such as (E,E)-2,4-decadienal and 2-pentylfuran, indicating a flavor-protective potential. In general, the reaction efficiencies and flavor quality of ultrasound-assisted heating are higher, and emulsifying performance is optimized by the conventional heating technology.
