    Influence of natural gas composition on adsorption in calcite Nanopores: A DFT study by Elbashier E.

    Published 2021
    “…The nanopores absorbed up to 28 and 24 molecules of CH4 and CO2, respectively, and the adsorption energy decreased to −0.0062 and −0.0075 eV/Å2 for each. Although the nanopore was filled spatially by the molecules, its surface still has an affinity to absorb more gas molecules energetically. …”

    EFFECT OF PHENOL AS A CONTAMINANT ON THE WILD PEARL OYSTER PINCTADA IMBRICATA RADIATA IN QATAR: ECOTOXICOLOGICAL APPROACH AND USE OF OYSTER SHELL STRUCTURE AS A POTENTIAL MITIGATIO... by BARAH, FARAHNAZ GHOLAMREZA

    Published 2022
    “…The highest phenol removal of real olive wastewater was at pH 10 and room temperature by OSNP-S (56.78%). Based on the adsorption isotherm model, the adsorption capacity decreased by temperature and the coefficient of determination R2 of the Freundlich adsorption isotherm model showed the best equilibrium data for phenol adsorption with the physical interaction adsorption process. …”

    Effect of using Cement Kiln Dust as a nano-material on the strength of cement mortars by Alnahhal, Wael

    Published 2017
    “…The CKD was milled up to 4 hours in a planetary ball mill. In addition to the control cement mortar mixture with 0% CKD, a total of 28 concrete mortar mixtures were prepared with four different replacement percentages of nano-CKD (5, 10, 15, and 20 %), and seven different milling times (1, 1.5, 2, 2.5, 3, 3.5, and 4 hours). …”
