This document contains 22 figures showing transmission electron microscopy (TEM) images and scanning electron microscopy (SEM) images of various nanomaterials, including CdSe nanocrystals, CdS nanowires, ZnO nanostructures, FeO(OH) and Fe2O3 nanostructures, silicon nanowire arrays, Ni-Cu nanowires, nanoparticle-supported composite structures, and biofunctionalized nanoparticles. The nanomaterials were synthesized using methods such as hydrothermal processing, thermal annealing, and ligand-assisted assembly. The images characterize the shapes, sizes, and arrangements of the nanostructures produced.
