Structure Characterization (IMAGE) Science China Press Caption Structure characterization on silver iodides filled in MWCNTs. HRTEM images of silver iodides inside MWCNTs viewed along different directions with corresponding structural models (insets: red - iodine, blue - silver). (a-c) HRTEM images with corresponding structural models (inset: red - iodine, blue - silver) along <1 0 0>, <1 1 1>, and <1 1 0> respectively. (d, e) The cross section and longitudinal section of structural model after molecular dynamics simulation. (f) Calculated radial distribution function and average number of neighbors of Ag-I (black line), Ag-Ag (red line) and I-I (blue line) within a sphere of radius r for Ag-I pairs (purple line).
