Prevention of Sn and Pb Crystallization in a Confined Nanospace

Sn, Pb, Ag, and Au are encapsulated within carbon nanotubes (CNTs) by capillary action. From high-resolution transmission electron microscopy imaging of the obtained materials, it is found that although Ag and Au crystallize within CNTs, Sn and Pb are in a pseudoliquid phase. The results suggest that a confined nanospace prevents crystal growth of metals having a low melting point.
