The Cohesive Energy of W and Mo Nanoparticles Based on Wulff Construction

The cohesive energy of W and Mo nanoparticles is modeled by considering W and Mo nanoparticles as Wulff construction. The energetic characteristics of Wulff construction is described by accounting for bond number in a system. The model predictions are consistent with the corresponding experimental results, especially when the diameter of nanoparticle is smaller than 1nm, which implies the closed packed structure for small nanoparticles.
