  "term": "Structural disorder",
  "field": "Chemistry",
  "definition": "Any deviation from a perfectly ordered, periodic arrangement of atoms or molecules within a material. This can include defects such as vacancies, interstitial atoms, dislocations, or a lack of long-range order in amorphous regions. In polymers, structural disorder often arises from irregular chain packing, varying tacticity, or the presence of different conformers.",
