The beginning of the XXI-st century can be seen as the start of a revolution in nanomaterials and nanotechnology which has already an impact on everyday life; this impact will grow rapidly in the near future. The need for international but also interdisciplinary cooperation and dissemination of knowledge in the field of nanoscale science and engineering is also becoming increasingly apparent. The common efforts of researchers from different countries and fields of science can bring complementary expertise to solve the rising problems in order to take the advantages of the nanoscale approach in materials sciences. Nanostructured materials are becoming of major significance, and their investigations require a comprehensive approach. The fundamental properties of these materials are remarkably altered as the size of their constituent grains or phases decreases to the nanometer scale. These novel materials made of nanosized building blocks offer unique and entirely different electrical, optical, mechanical, and magnetic properties compared to conventional micro- or millimetre-size materials owing to their distinctive size, shape, topology, surface properties, etc.
