    Effect of Carbonyl Iron Particle Types on the Structure and Performance of Magnetorheological Elastomers: A Frequency and Strain Dependent Study by Salem, Ayman M. H.

    Published 2022
    “…Each MRE composition have three different concentrations, which is 5%, 10%, and 20% by volume. The dynamic properties of the fabricated samples are tested by compression oscillations on a dynamic mechanical analyzer (DMA). …”

    Nanoclay compatibilization of phase separated polysulfone/polyimide films for oxygen barrier by Ammar, Ali

    Published 2017
    “…Thermal decomposition (TGA) measurements of PSF/PI films showed a decrease in thermal stability upon adding C30B due to its surfactant modification, while film mechanical tensile modulus properties improved slightly by adding low concentration of C30B (~ 1 mass%), but higher nanoclay loading decreased tensile strength and elongation at break. …”

    Allelopathic effects of the invasive Prosopis juliflora (sw.) Dc. On seed germination of selected Qatari native plant species by Bibi, Shazia

    Published 2016
    “…In order to achieve the goals, aqueous extract of P. juliflora was made by immersing 100 g/l of powdered parts of plant in warm distilled water (∼50°C) for 24 hours with regular mixing. Whatman filter paper was used to filter the obtained brownish solution. …”

    The mechanical and adhesive properties of electrically and thermally conductive polymeric composites based on high density polyethylene filled with nickel powder by Krupa, Igor

    Published 2013
    “…The stress at break of the composites behaved nonlinearly; the low filler content suppressed necking, resulting in a decrease in stress at break, whereas higher filler content (higher than 10vol.%) led to reinforcement of the composites and therefore increased the stress at break.The presence of nickel particles throughout the HDPE matrix increased the hydrophilicity of the composites. …”

    Possible evidence for the existence of a hairy layer at the surface of polymer latex particles by Said, Ziad F. M.

    Published 1998
    “…At low levels of electrolyte (NaCl in the range 0.00- 0.10M), the hydrodynamic radius (dH) was found to decrease gradually, reaching a minimum value at 0.10M, about 7-9nm smaller than the original value in the absence of electrolyte. …”

    The effects of oxygen concentration on in vitro output of prostaglandin E2 and interleukin-6 from human fetal membranes. by Al-Asmakh, Maha

    Published 2007
    “…In this study, we have investigated the effect of oxygen tension on fetal membrane biology, as a reconsideration of the literature suggests that fetal membranes are normally exposed to approximately 3% O(2) (approximately 20 mmHg) in vivo, rather than the 20% O(2) (150 mmHg) used for in vitro culture. …”
