Morphologies of the products that evolved with the reaction time. (a) A crystal cell describing the main direction and three sub-directions. (b) Schematic diagram of the dendritic AgCl showing the dendrite's trunk grow along <111> direction. (c) SEM image of AgCl sub-dendrites; the insets are the amplified pictures of the two squares, and the roots of the sub-dendrites are plane. (d) Schematic diagram of the cube at the assembling center with eight plane  faces. (e) High-resolution SEM images of the octagonal assembled site. (f) SEM image of the assembled octagonal dendritic AgCl crystal structures.
