Figure 7: Electron energy loss spectroscopy from two hafnia nanorods before and after heating.
From: Real-time atomistic observation of structural phase transformations in individual hafnia nanorods
(a,c) HAADF image and EEL spectrum, respectively, of a nanorod before heating. The oxygen K-edge is present. (b,d) HAADF image and EEL spectrum, respectively, of a different wire after heating and cooling. No oxygen K-edge is present, indicating the reduction of the rod to hafnium metal. Both scale bars are 5 nm.
