Summary

A general approach to the study of the structure of all known forms of the solid state and of biological structures is possible on the basis of the concept "module" that is more general and unambiguous than "the lattice". Potentialities of modular design for the estimation of the opportunities of their self-organization due to formation of perfect coherent boundaries between their regularly oriented crystallites in nanocomposites were shown by the examples of two-dimensional Penrose mosaics. There have been shown potentialities of combinatorial polymodular models for analyzing cooperative mechanisms of transformations Al2O3, the reversible growth dissolution of spinel inclusions in corundum, as well as dissolution of "tetrahedral anions" [SiO4], [MoO4] and [WO4] in amorphous corundum.
