## Description

- description: 'We report structures of polycrystalline frameworks by uncovering the
    coexistence of different morphologies and their static and dynamic behaviors,
    disclosing a realistic picture and multiple-scale insights into structures of
    the most frequently used polycrystalline frameworks. Visualization with high-resolution
    transmission electron microscopy revealed four distinct morphologies, i.e., nanoparticle
    aggregates, nanorod aggregates, ultrathin nanosheets, and parasitic fusion entities.
    Moreover, direct visualization revealed the existence of different polygons and
    channels and their contents together with their boundaries and unstructured complements. '
