    The Influence of Qatari Dust on the Element Composition of Marine Plankton حسب Yigiterhan, Oguz

    منشور في 2021
    "…The excess concentrations relative to average dust from Qatar for most elements (except Cd) decreased with distance from shore. This may be due to contamination or uncertainties with the lithogenic correction or due to our sampling locations in a marginal sea, dominated by dust input. …"

    The Optical and Electrical Properties of Low Density Polyethylene Films in CuSo4 Solution حسب Al Naimi, Sabah M. [صباح النعيمي]

    منشور في 2005
    "…The results of this study show that: (1) Direct and indirect optical transitions exist, (2) Direct and indirect energy gaps increase as the exposure time increases, (3) The Urbach energy band tail decreases as time increases, (4) The d.c. conductivity decreases, while the dielectric constant increases as time increases. …"

    Prevention of gallium arsenide photocorrosion by an epoxy adhesion layer حسب Alqaradawi, Siham Y.

    منشور في 2004
    "…The room temperature electrical conductivity of the epoxy films increased from 10−8 to 10−4Ω−1cm−1 due to gold impregnation. Enhancement of the photocurrent due to gold impregnation is attributed due to better conduction of the photogenerated holes into the electrolyte, also due to activating the adsorption of electrolyte ions.Several parameters are studied with the objective of determining the stability of epoxy films: these are continuous current–voltage (I–E) scans, prolonged illumination, weight changes and surface topography by scanning electron microscopy. …"

    Morphology, Nucleation, and Isothermal Crystallization Kinetics of Poly(ε-caprolactone) Mixed with a Polycarbonate/MWCNTs Masterbatch حسب Gumede, Thandi P.

    منشور في 2017
    "…The nanocomposites contained 0.5, 1.0, 2.0, and 4.0 wt % MWCNTs. Even though PCL and PC have been reported to be miscible, our DSC (Differential Scanning Calorimetry), SAXS (Small Angle X-ray Scattering), and WAXS (Wide Angle X-ray Scattering) results showed partial miscibility, where two phases were formed (PC-rich and PCL-rich phases). …"
