We report on the development of a simple and efficient method to predict the structural transition and the bulk-to-nano transformation of spherical FCC and BCC solid nanoparticles using the surface atomic packing fraction (). For both structures, 's are maxima at radii equal to the nearest neig...
This means that the atoms of a unit cell only occupy a part of the unit cell; only a fraction of it. This fraction is called the packing fraction of the unit cell and is given as {eq}\displayst...
