Abstract
This work addresses the characterization of the high temperature reactions between different nanoparticles oxides, CeO2-ZrO2 and CeO2-SnO2, by the direct observation of the phenomenon by in situ High Resolution Transmission Electron Microscopy (HR-TEM). The changes in the size and morphology of the nanoparticles, and the phase transformations that can occur during the reactions will be do…
