This study explores the recovery of high-quality humic substances (HS), specifically humic acids (HA) and fulvic acids (FA), from anaerobically digested sewage sludge (DSS) using ultrasound-assisted extraction (UAE). Implementing this step prior to downstream digestate management, positions DSS as a low-cost, sustainable feedstock to produce high-value agronomic biostimulants and soil conditioners. Response surface methodology (RSM) was applied to optimize the UAE parameters, namely ultrasound amplitude (20–100%) and extraction time (5–20 min), to maximise HA yield. A second-order polynomial model demonstrated a strong fit to the experimental data (R<ce:sup loc=\"post\">2</ce:sup> ≥ 0.90), achieving HA and FA yields of 424.67 ± 0.03mg g<ce:sup loc=\"post\">−1</ce:sup> and 419.04 ± 0.01 mg g<ce:sup loc=\"post\">−1</ce:sup> (dry basis), respectively. Under optimized conditions (97% amplitude, 8.4 min, 0.1 M KOH, 1:40 v/w), HA yields increased by 109% compared to conventional extraction (CE: 200 rpm, 16 hrs), with a concurrent 85.8% reduction in energy consumption (CE: 0.281 kWh vs. UAE: 0.03 – 0.04 kWh). Elemental profiling highlighted the superior quality of UAE-HAs, characterised by significant carbon intensification (44.64% vs 37.9%), nitrogen recovery (6.69% vs 0.74%) and sulphur enrichment (1.95% vs 0.07%) relative to the commercial standard. Spectrometric analysis further corroborated these findings, revealing greater functional group diversity in DSS-derived samples, positioning them as superior candidates for agricultural applications. These findings demonstrate the potential of UAE as an efficient, and economic, technology for HS recovery, advancing the circularity of digestate based biorefineries by transforming urban organic waste streams into value-added agronomic resources.","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"26 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147752735","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}

An efficient carotenoid extraction method, together with knowledge of its carotenoid compositions, is essential to support broader utilization of this intriguing fruit. Herein, we present a sustainable and efficient carotenoid extraction method by integrating ultrasound-assisted extraction (UAE) with green solvent systems. Seven solvent systems were initially screened for their extraction efficiencies with and without UAE. Among them, a deep eutectic solvent, 1:1 menthol:camphor (Men:Cam), stood out as an effective solvent. Interestingly, UAE also dramatically improved the efficiency of edible oils, <em>e.g.,</em> sunflower oil. Response surface methodology (RSM) was then employed to elucidate the correlations among parameters (solvent ratio, temperature, and time) that affect the extraction efficiency in selected systems. For example, the optimal condition for Men:Cam (1:2, 39 °C, 32 min) yielded predicted total carotenoid contents (1.87 ± 0.06 µg/mL) with only 10.4% deviation from experimental values, hence demonstrating the robustness of this approach. Importantly, liquid chromatography – mass spectrometry (LC-MS) revealed a unique carotenoid profile of calamansi juice, which consisted of lutein, β-cryptoxanthin, and their esterified derivatives (C10:0 – C18:0). Last but not least, greenness evaluation using the AGREE metric confirmed significant improvement of the optimized 1:1 Men:Cam system over the conventional extraction. Overall, this work demonstrates that UAE combined with green solvent systems is a practical tool for sustainable carotenoid extraction from valuable agricultural products.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"127 ","pages":"Article 107764"},"PeriodicalIF":9.7,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146135083","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}

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}

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.
