    Recovery of Bioactive Constituents from Olive Leaf Pruning Waste of Five Different Cultivars: A Comparison of Green Extraction Techniques to Maximize Health Benefits by Hamid Mushtaq, Simona Piccolella, Jose A. Mendiola, Lidia Montero, Elena Ibáñez, Severina Pacifico

    Published 2025-01-01
    “…Sequential ultrasound-assisted maceration (UAM) in <i>n</i>-hexane and ethanol was compared with a compressed fluid extraction strategy consisting of supercritical fluid extraction (SFE) and pressurized liquid extraction (PLE) for their efficiency in recovering distinct classes of bioactives. Chemical profiling by UHPLC-HR-MS/MS (ultra-high-performance liquid chromatography high-resolution tandem mass spectrometry) and GC-MS (gas chromatography mass spectrometry) showed that UAM-EtOH effectively extracted polyphenols (especially luteolin derivatives) and triterpenes (notably maslinic acid), while PLE yielded the highest amount of secoiridoids (e.g., secologanoside). …”

    Study on the performance and mechanism of graphene oxide / polyurethane composite modified asphalt by Tengteng Guo, Zhenxia Li, Yuanzhao Chen, Qingyu Xu, Jing Wang, Lihui Jin

    Published 2025-01-01
    “…The surface of the modified composite asphalt is relatively smooth, exhibiting a stable network structure, thus solving the PU segregation problem in the matrix asphalt.The change of infrared spectrum absorption peak shows that reaction between isocyanate groups in polyurethane and aromatic esters in bitumen, GO oxidizes with the-CH functional group in asphalt, and the content of C = C double bond changes during the modification process, indicating that the modification of asphalt by GO and PU is a composite modification based on chemical modification and supplemented by physical modification.…”
