Figure 65.

(a–e) SEM images of the surface of the Zn sheet: (a) Low-magnified image before the microwave irradiation. (b) Low-magnified image after the microwave irradiation. (c) Medium-magnified image after the microwave irradiation. (d) High-magnified image after the microwave irradiation; (e) TEM image of a ZnO nanoneedle.
