    Phase Behavior, Filling Dynamics, and Packing of Fluids inside Isolated Carbon Nanotubes by Faucher, Samuel James

    Published 2022
    “…Third, we develop continuum elastic shell theories to explain why double-walled nanotubes, but not single-walled nanotubes, can distinguish between interior fluid filling and exterior fluid adsorption by changes in radial vibrations alone. Fourth, we perform a thermodynamic analysis of water-filled, closed carbon nanotubes, calculating enthalpies of phase change from a Clausius-Clapeyron type expression for nanoconfined water. …”

    Synthesis of mesoporous mcm-41 and sba-15 silica for determination of organophosphorous pesticides in fruit samples by using dispersive and magnetic solid phase extractions / Nur H... by Zainal Abidin, Nur Husna

    Published 2020
    “…Mesoporous silica MCM-41 and SBA-15 were successfully synthesized and characterized using fourier transform infrared (FTIR) spectroscopy, x-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), nitrogen adsorption-desorption analysis and vibrating sample magnetometer (VSM). MCM-41 and SBA-15 were employed as sorbents in the dispersive solid phase extraction (DSPE) of three OPPs including chlorpyrifos, diazinon and parathion methyl. …”
