, Germany 10.3762/bjnano.5.172 Abstract Grain/interphaseboundaries/interfaces of varying misorientations, free volume fractions, curvatures and irregularities are present in materials, both 3D and 2D, regardless of whether these materials are crystalline or amorphous/glassy. Therefore, a question arises
about the central idea on which a general description of grain/interphaseboundaries/interfaces can and should be based. It is suggested that a generalized model of a structural/basic unit (crystalline, non-crystalline or of any scale), which depends on the interatomic (including electronic
processes connected to a problem on hand is contained within this representative volume. The unresolved issues are identified.
