Figure 3

Correlation of images from SEM with the chemical spectrum obtained in the SEM-EDS spot analyses. Area of spectrum 1 (a), area of spectrum 2 (b), and area of spectrum 3 (c) of the UEF-3 sample. The spots analyzed are outlined by a red circle. Graph (d) presents a comparison between the photomicrographs (a, b, and c) of the % of each chemical element.
