The surface tension of nanoparticles (γn) is obtained by analyzing SDE data on the basis of the Kelvin equation, while EB is obtained by reanalyzing the SDE data. By comparing the size-dependent melting and the SDE of nanoparticles, γ is evaluated 关键词: binding energy;evaporation;nanoparticles;surface tension;size-dependent evaporation;surface tension;cohesive energy;free nanoparticles;Kelvin equation;melting
