What the paper reports

Researchers determined crystal structures of ramelteon and tolvaptan using three-dimensional precession electron diffraction tomography on approximately 500-nanometer crystals. Structures from subsequently grown, much larger crystals were measured by single-crystal X-ray diffraction for comparison. Agreement in molecular conformation, packing, and unit-cell parameters supported the electron-diffraction workflow for these two pharmaceutical materials.

Why this paper is included

A direct API benchmark against single-crystal X-ray structures provides stronger application evidence than an instrument demonstration alone.

The interpretation above is analysis, not a conclusion attributed to the original source.
