    The Analysis of the Transformation Mechanism of cBN Crystals with the First-Principle Calculation by Lichao Cai, Bin Xu, Meizhe Lv, Xiaohong Fan

    Published 2020-01-01
    “…To clarify the synthesis mechanism of cubic boron nitride (cBN) with catalysts at high temperature and high pressure, we calculate the surface energy of the main phases in the Li-N-B synthesis system using the first-principle method. Based on the density functional theory, the surface energy of low-index surfaces of cBN, hexagonal boron nitride (hBN), and lithium boron nitride (Li3BN2) at the cBN synthetic temperature of 1700 K and synthetic pressure of 5.0 GPa is calculated. …”

    First-Principles Study on Adsorption and Decomposition of NOx on Mo (110) Surface by Yunmi Huang, Haijun Luo, Changkun Dong

    Published 2021-01-01
    “…Based on the density functional theory, the adsorption and decomposition of NOx (x = 1, 2) on Mo (110) surface are studied with first-principles calculations. Results show that the stable structures of NO2/Mo (110) are MoNO2 (T, μ1-N), MoNO2 (H, μ3-N, O, O′), MoNO2 (S, η2-O, O′), and MoNO2 (L, η2-O, O′). …”
