In this regard, the cause of difference in various experimental data is introduced, which is the difference between nanoparticles’ grain Gaussian distribution. This volume-depended model with the help of the Gaussian distribution can describe the relation between nanoparticle melting temperature and its size. The obtained results are interestingly consistent with reported experimental data. </em> https://www.ijnnonline.net/article_24537_f8c3d303b667784148f7c66bc4d9845c.pdf
