From: Size-Dependent Melting Behavior of Colloidal In, Sn and Bi Nanocrystals

Transmission electron microscopy images of (a) 14.9 ± 0.7 nm Bi nanocrystals, (b) 17.0 ± 1.1 nm Sn nanocrystals and (c) 17.0 ± 1.1 nm In nanocrystals. Corresponding images of the (d) Bi, (e) Sn and (f) In nanocrystals after dispersion into the polyimide resin matrix illustrate that the size and shape of the nanocrystals are preserved during sample preparation (the scale bar is 50 nm).
