the experimental and calculated melting temperatures of spherical Sn and
Pb nanoparticles, respectively. For nonspherical nanostructures, Figure
2.6a shows the melting temperature of indium nanowires as a function of
wire diameter and Figure 2.6b shows the melting temperature of an
indium nanofilm as a function of film thickness.
