New materials/electronic structure in 21 st century

New materials/electronic structure in 21 st century. Typical features: - multi-component, hierarchies - 0-3D (dots, chains, layers ... ) - d- and f- elements - H: proton as a quantum part. - organic/inorganic/solid - bioinspired. Challenges: - lack of a "unifying" strategy
