    Pd nanocrystals encapsulated in MOF-derived Ni/N-doped hollow carbon nanosheets for efficient thermal CO oxidation: unveiling the effect of porosity حسب Ipadeola, Adewale K.

    منشور في 2023
    "…Conspicuously, the T100 of Pd/Ni-MOF-HNC was lower than those of most previously reported Pd-based catalysts due to the high porosity, surface area, and electronic interaction of Pd/Ni-Nx, and Ni-metal defects, which promote the adsorption/activation of reactants (CO + O2), decrease the activation energy to 73.1 kJ mol−1 and enhance the reaction rate at the same CO conversion percentage. …"

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

    منشور في 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. …"

    Influence of natural gas composition on adsorption in calcite Nanopores: A DFT study حسب Elbashier E.

    منشور في 2021
    "…The nanopores absorbed up to 28 and 24 molecules of CH4 and CO2, respectively, and the adsorption energy decreased to −0.0062 and −0.0075 eV/Å2 for each. Although the nanopore was filled spatially by the molecules, its surface still has an affinity to absorb more gas molecules energetically. …"
