  "id": "MLC-T-CHM-009437",
  "term": "Primary nucleus",
  "field": "Chemistry",
  "definition": "A stable, microscopic region of ordered polymer chains that forms spontaneously from a disordered melt or solution during the initial stages of crystallization. This entity acts as a template for further crystal growth, initiating the formation of larger crystalline structures. Its formation requires overcoming an energy barrier, and its size must exceed a certain threshold to be stable.",
