Traditionally, chemistry has been developed to obtain thermodynamically stable and isolable compounds such as molecules solids by chemical reactions. However, recent developments in computational have placed increased importance on studying the dynamic assembly disassembly of atoms formed situ. This study directly visualizes formation dissociation dynamics labile dimers trimers at atomic resolution with elemental identification. The video recordings many homo- hetero-metallic are carried out combining scanning transmission electron microscopy (STEM) identification based Z-contrast principle. Even short-lived low probability existence AuAg, AgCu, AuAgCu visualized a result identifying moving doses.
