    Influence of nitrogen doping on the electrocatalytic activity of Ni-incorporated carbon nanofibers toward urea oxidation by Barakat, Nasser A.M.

    Published 2017
    “…However, the electrochemical measurements indicated that the content of the urea in the initial electrospun solution should be optimized as the results showed that the best nickel surface activation as well as the maximum observed current density can be achieved when the urea content is kept at 5 wt%. Typically, the observed current densities using 1.0 M urea (in 1 M KOH) were 3.15, 29.7, 13.75, 47.55, 14.13 and 9.85 mA/cm2 for the nanofibers obtained from electrospun solutions having 0, 1, 2, 5, 7 and 9 wt% urea, respectively. …”

    Collision/reaction cell ICP-MS with shielded torch and sector field ICP-MS for the simultaneous determination of selenium isotopes in biological matrices by Al-Saad, Khalid A.

    Published 2011
    “…The determinations of selenium isotopes in biological samples were performed using both inductively coupled plasma collision/reaction cell quadruple mass spectrometer (CRC-ICP-QMS) and inductively coupled plasma sector field mass spectrometers (SF-ICP-MS). To significantly decrease the argon-based interferences at m/z 74 (36Ar38Ar), 76 ( 38Ar38Ar, 40Ar36Ar), 78 ( 38Ar40Ar), and 80 (40Ar40Ar), the gas-flow rates of a helium and hydrogen mixture used in the collision cell were optimized to 1.0 mL/min H2 and 3.5 mL/min He. …”

    Seasonal Variations of Acoustic Properties in Ropme Sea Area by El Gindy, A. A. H. [احمد عبد الحميد الجندي]

    Published 1993
    “…The horizontal distributions of the anomaly of the vertically averaged sound speed from 1500 m/s showed a minimum deviation (5-10 m/s) in the area delineated by 22-24°N and 60-62°E, i.e., in Gulf of Oman where the depths exceed 2000 meters. …”

    Improved mechanical properties of recycled linear low-density polyethylene composites filled with date palm wood powder by AlMaadeed, Mariam A.

    Published 2014
    “…The Young’s modulus of the composites significantly increased as the filler content increased over the entire concentration range. A maximum value of 1989MPa was observed for the composite filled with 70wt.% filler, which was approximately 6.5times higher than that observed for neat RLLDPE. …”
