WebHerein, since van der Waals (vdW) interactions play an important role in these systems, therefore, we have used the PBE + D2 method of Grimme [72] ... the second-order elastic constants are calculated using RP approximation. We find that C 11 = C 22 = 240.05 N/m, C 12 = 82.58 N/m. These elastic constants fulfill the mechanical stability ... WebLi [8,9] had extended the (1) approach of one drop or bubble toward another or a fluid– model of Hahn et al.
