    Correlated decay of triplet excitations in the shastry-sutherland compound SrCu2 (BO3)2 حسب Zayed, M.E.

    منشور في 2014
    "…The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu2(BO3)2 is studied by means of inelastic neutron scattering. The excitation amplitude rapidly decreases as a function of temperature, while the integrated spectral weight can be explained by an isolated dimer model up to 10 K. …"

    Experimental and Theoretical Investigation on Bond Behavior of Tensile Lap Spliced Basalt Fiber Reinforced Polymer Bars in High Strength Concrete Beams حسب Eltantawi, Islam Reda Mohamed

    منشور في 2020
    "…Moreover, the bond strength decreases as the splice length increases. Additionally, the sand-coated bars showed a higher bond strength than the helically wrapped bars.…"

    Facile Electrochemical Synthesis of Highly Efficient Copper-Cobalt Oxide Nanostructures for Oxygen Evolution Reactions حسب Nath, Narayan Chandra Deb

    منشور في 2020
    "…An optimized nanopetal structure of CuxCo3-xO4 (x = 0.95, annealed at 200 °C) shows a considerably high Faradaic efficiency (∼93%) with a remarkably low overpotential (∼230 mV) at a benchmark current density (J) of 10 mA cm-2; at the same J in an alkaline solution (1 M KOH) for OER, it also exhibits high durability (up to 100 h). …"
