    Impact of trace noble metals on the catalytic performance of LaNiMgO towards methane dry reforming حسب Mohamed, Assem T.

    منشور في 2024
    "…The incorporation of noble metals enhanced Ni dispersion on the support and facilitated the Ni reducibility due to the H2 spillover effect. At 650 °C and in the early stages of the reaction, all catalysts exhibited enhancement in the catalytic activity. …"

    Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather حسب Oualha, Meriam

    منشور في 2020
    "…Their optimal potentials was at wide ranges of temperature from 30 °C to 42 °C and pH from 7.0 to 8.0. Using Qatari bacteria in liquid cultures and at syringe level at laboratory conditions, as well as in plots at field conditions, 16% CaCO3 increase in minerals formation was obtained, leading to 7% increase of soils stability. …"

    The investigation of treatment design parameters on carbon integration networks حسب Alnouri, Sabla Y.

    منشور في 2023
    "…Furthermore, it was discovered that for net capture targets of 20% and 25%, no revenue from carbon storage could be generated beyond a solvent temperature of 25 °C. Additionally, the optimal diameter of the treatment column was more responsive to changes in solvent temperature for cases with low net capture targets (below 10%), while its sensitivity decreased for higher capture targets (above 10%). …"

    Conversion of a mixture of date palm wastes to mesoporous activated carbon for efficient dye adsorption حسب Alharbi, Hattan A.

    منشور في 2023
    "…The MAC was found to be mesoporous, with an average pore diameter and BET surface area of 2.61 nm and 641.23 m2 g−1, respectively. The zeta potential and FTIR results demonstrated that the surface of MAC was negatively charged in its natural state and filled with functional groups such as phenyl, secondary amine, alkyne, aldehyde, and hydroxy groups. …"
