  • Nanocrystalline materialWikipedia

    Definitions vary but nanocrystalline material is commonly defined as a crystallite (grain) size below 100 nm. Grain sizes from 100–500 nm are typically considered "ultrafine" grains. The grain size of a NC sample can be estimated using x-ray diffraction. In materials with very small grain sizes the diffraction peaks will be broadened.

  • CocrystalWikipedia

    The meaning of the term cocrystal is subject of disagreement. One definition states that a cocrystal is a crystalline structure composed of at least two components where the components may be atoms ions or molecules. This definition is sometimes extended to specify that the components be solid in their pure forms at ambient conditions.
