Nanoscience and Nanotechnology. Common Outlook - From Past to Future

Various aspects, achievements, perspectives and problems of nanoscience and nanotechnology are considered. The nanoscience and technology are part of natural sciences including physicochemistry of ultramicroparticles of substances, molecules, two-dimensional systems and other objects with sizes in 1-100 nanometres. Nanotechnology as a consequence of nanoscience operates with subjects of above-named sizes and their precursors, i.e. atoms with sizes up to 500 picometres (decimal parts of nanometres).
