We study the size dependencies on melting of Gold nanoparticle. The nanoparticles are built with different sizes and heated up with same temperature gradient from room temperature up to 1400 K. The trajectories of the atoms are investigated based on Molecular Dynamics (MD) simulation. Pressure evolution as a function of time shows the oscillation pattern as in the case of thermal induced melting. Analysis based on structure factor combined with Common Neighbour Analysis (CNA) indicated the properties of melting depends on nanoparticle sizes.
