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

    منشور في 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 using Cement Kiln Dust as a nano-material on the strength of cement mortars حسب Alnahhal, Wael

    منشور في 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). …"
