What the paper reports
Combining cryogenic specimen preparation with three-dimensional electron diffraction, researchers followed glycine crystallization from water. Different samples captured the sequential appearance of its three ambient-pressure polymorphs, including a short-lived beta form before alpha became dominant. Structures could be obtained from very small crystallites, demonstrating how diffraction can reveal phases missed by slower bulk measurements.
Why this paper is included
This model-system study makes electron diffraction relevant to polymorph screening and crystallization mechanisms, beyond determining a single static structure.
The interpretation above is analysis, not a conclusion attributed to the original source.
