    Electrocoagulation treatment of reject brine effluent from Solvay process حسب Osman M.A.

    منشور في 2019
    "…When no current was applied, removal of the ions was insignificant. Applying a current density of 0.1167 A/cm2 increased the removal percentages of NH4+ and Cl– by 71.6% and 26.9%, respectively, which proved that the removal was due to electrocoagulation. …"

    Antiferromagnetism in EuPdGe3 حسب Albedah, M.A.

    منشور في 2014
    "…EuPdGe3 crystallizes in the BaNiSn3-type tetragonal structure (space group I4mm) with the lattice constants a=4.4457(1)Å and c=10.1703(2)Å. The results are consistent with EuPdGe3 being an antiferromagnet with the Néel temperature TN=12.16(1)K and with the Eu spins S=7/2 in the ab plane. …"

    Enhancing the corrosion resistance of reinforcing steel under aggressive operational conditions using behentrimonium chloride حسب Radwan A.B.

    منشور في 2019
    "…Using only a 50 ?mol L?1 of BTC, we are able to measure an inhibition efficiency of 91, 79, and 71% in SCP solution with 3.5% NaCl at pH of 12.5, 10 and 7, respectively without showing any effect on the mechanical properties on the cured mortars. …"

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

    منشور في 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. …"
