Fig. 13: TEM images and SAED pattern of amorphous region.
From: Dissolution and precipitation behaviors of zircon under the atmospheric environment

a Bright-field TEM image, b SAED pattern, obtained from amorphous region of the zircon immersed in 0.1 M NaOH (aq). The scale bar on the left image is 50 nm, the right is 10 nm−1.
