  "id": "MLC-T-CHM-005279",
  "term": "Hexagonal mesophase",
  "field": "Chemistry",
  "definition": "A liquid crystalline phase characterized by a hexagonal arrangement of cylindrical aggregates. These aggregates are formed by the self-assembly of amphiphilic molecules, such as block copolymers or surfactants, in a solvent. The cylinders are packed in a two-dimensional hexagonal lattice, exhibiting long-range positional order in the plane perpendicular to the cylinder axes.",
