Atomic-Level Observation of Disclination Dipoles in Mechanically Milled, Nanocrystalline Fe. ''Science'' 29 (2002) 2433. 〕 In analogy with dislocations in crystals, the term, ''disinclination'', for liquid crystals first used by F. C. Frank and since then has been modified to its current usage, ''disclination''.〔S.
