    Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments حسب Almomani F.

    منشور في 2020
    "…The results revealed that the highest cumulative methane production (CMP) of 297.99 NL/kgVS can be generated by co-digestion of ASWs and CD at a ratio of 60:40. Further improvement was achieved via alkalinity treatment with 1.0 g of NaHCO3/gVS leading to decrease in lignin, cellulose, and hemicellulose contents of feedstock by 3.5%, 10.5% and 15.9%, respectively, converting them to soluble fractions and improving the CMP by 11.2–29.7% based on substrate quality. …"

    Study of performance, combustion, and emissions parameters of DI-diesel engine fueled with algae biodiesel/diesel/n-pentane blends حسب Elkelawy, Medhat

    منشور في 2021
    "…Due to the disadvantages of using pure biodiesel in engines, it was used as B50 (a blend of 50% diesel and 50% biodiesel). To enhance engine performance, n-pentane was used in different extents of 5, 10, and 15 ml per liter as an enhancer additive. …"

    Performance of sustainable concrete incorporating treated domestic wastewater, RCA, and fly ash حسب Abushanab, Abdelrahman

    منشور في 2022
    "…Test results revealed that TWW slightly reduced concrete mechanical properties by 6% to 12%, while it drastically reduced the chloride permeability by 77% in comparison with freshwater concrete. In addition, RCA decreased concrete compressive and flexural strengths by 21% and 10%, respectively, compared to natural aggregate concrete. …"
