Dialogue is the elementary cell of communication experience.

Since an elementary cell of the lattice has a basis of two atoms, the wave function has an effective 2-spinor structure.

Consequently, the electric centers of positive and negative charges are displaced of an elementary cell from equilibrium positions, i.e., the spontaneous polarization of the crystal changes.

In these crystals an elementary cell includes several molecules sitting in symmetrically identical positions, which results in the level degeneracy that is lifted by intermolecular interaction.

If molecules have a greater affinity for the opposite enantiomer than for the same enantiomer, the substance forms a single crystalline phase in which the two enantiomers are present in an ordered 1:1 ratio in the elementary cell.

The structures investigated are similar to the two kinds of structures in a two-dimensional, two-component positive-temperature Coulomb gas but the location of the elements of the system within the region of the elementary cell of the structure is different.

Recent elementary cell histology8 shows without doubt, that cells close to each other, such as those found in the early blastomere surrounded by the Zona Pellucida, are not developing in splendid isolation, but continually exchange information which limits or controls each other’s growth extent and pattern.

It is an important property of typical molecular crystals with two or more symmetrically-equivalent molecules in the elementary cell, such as benzine and naphthalene, that their exciton absorption spectra consist of doublets (or multiplets) of bands strongly polarized along the crystal axes as was demonstrated by Antonina Prikhot'ko.

The Pilling-Bedworth ratio (P-B ratio), in corrosion of metals, is the ratio of the volume of the elementary cell of a metal oxide to the volume of the elementary cell of the corresponding metal (from which the oxide is created).
