Background:

• Morphology, the arrangement of atoms and molecules into distinct phases, is fundamental to materials synthesis and applications like catalysis and colloid chemistry.
• Controlling morphology evolution is crucial for the rational design of complex materials.
• Nature provides inspiration, with biological materials like bone showcasing hierarchical self-assembly and biomineralization.

Purpose of the Study:

• To review research utilizing cryogenic transmission electron microscopy (cryoTEM) to understand morphology evolution in materials.
• To demonstrate how direct observation of structural changes aids in controlling materials synthesis.
• To bridge insights from natural materials with synthetic approaches for advanced materials design.

Main Methods:

• Utilizing cryogenic transmission electron microscopy (cryoTEM) for high-resolution, real-time observation of materials in solution.
• Tracking structural evolution with nanometer spatial and sub-second temporal resolution.
• Analyzing morphology changes in macromolecular self-assembly, inorganic nucleation/growth, and hybrid material co-evolution.

Main Results:

• CryoTEM directly observed morphology evolution in diverse systems, including self-assembling macromolecules and inorganic crystal growth.
• Understanding these dynamic processes is essential for controlling the final structure and properties of synthesized materials.
• Insights gained facilitate the design of complex, hierarchical materials inspired by biological systems.

Conclusions:
