Two-dimensional Crystallization of Hexagonal Bilayer with Moiré Patterns

On the Cover: Direct observation of two-dimensional crystallization dynamics in water. Direct observation of crystallization dynamics in real space is of special interest to scientists in various disciplines. Unidirectional packing of microbeads in a confined channel served as the experimental model system because their dynamics can be observed and recorded readily in the laboratory as a result of their large size and slow time scale. Formation of grain boundaries, disorder–order transitions, and height-dependent polygonal tiling are all captured using this platform.
