Cohesive energy versus the size of the nanostructure for molybdenum (Mo) and tungsten (W). The solid lines indicate the theoretical prediction with Eq. 3. for Mo and W nanoparticles. The symbols are the experimental values of Mo [28] and W [28] nanoparticles. The cohesive energies of the corresponding bulk Mo and W are 6.19 eV [29] and 8.54 eV [29]
