    Tailoring optical absorption in silicon nanostructures from UV to visible light: A TDDFT study by Hassan, Walid M.I.

    Published 2016
    “…Our main findings are that: (i) The oscillator strength as a function of length is quadratic at small lengths, and then increases linearly. (ii) The exciton binding energy is seen to decrease by approximately 45% from 0.67 eV to about 0.3 eV with length increase, for a nanostructure with a cross-section diameter of approximately 12 Å. …”

    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). …”
