Böcker av Giovanni Ferraris

The articles published in this Special Issue reprint offer a sound update of research fieldswhere the concepts of modular crystallography are important and provide unique keys tounderstand and to solve problems of structural crystallography. Polytypism,polysomatism, and twinning are fertile fields of research, and their basic principles-o����en coupled with the OD (order-disorder) theory-are powerful tools to solve andclassify related crystal structures. Research on twinning and its consequences onstructure and properties of crystalline materials is cutting-edge, e.g., dealing withrelations between twin walls and piezoelectricity.
