    Effect of reinforcement concentration on the properties of hot extruded Al-Al2O3 composites synthesized through microwave sintering process by Reddya, M. Penchal

    Published 2017
    “…Results showed that, as the content of hard ceramic particles increases, it improves overall mechanical properties including microhardness, 0.2% yield strength, ultimate compression/tensile strength, and Young's modulus while the ductility and co-efficient of thermal expansion decreases. XRD patterns and SEM/EDS mapping images show a uniform distribution of Al2O3 particles in the Al matrix. …”

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

    Published 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 by Alqaradawi, Siham Y.

    Published 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. …”
