    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. …"

    Mechanical and microstructure characterization of hard nanostructured N-bearing thin coating حسب Cabibbo, M.

    منشور في 2015
    "…The main problem with steel, is that it exhibits a relatively low hardness (below 10GPa) which strongly decreases upon annealing above about 600K. …"

    Curcumin a Colorimetric and Fluorimetric Cyanide Probe in Aqueous System and Living Cells حسب Hijji, Yousef

    منشور في 2019
    "…Cyanide causes a dramatic color change of the curcumin solution (acetonitrile : water 90 : 10) from bright yellow to dark orange. It causes dramatic spectral changes in the UV-vis spectrum of curcumin by the decrease in the absorption band intensity at 421 nm and a concomitant appearance of a strong band at 520 nm. …"
