DO THE SIZE EFFECTS EXIST?

In this paper we consider a size effect on nanoscale. By analyzing a series of examples we show that various intensive macroscopic characteristics of nanoobjects exhibit non-trivial size dependencies on the scale of 200 to 40 angstrom. Drastic variations take place for sizes in the region 50 angstrom for ordinary systems, and 60-200 angstrom in the case of magnetic systems. We argue that X-ray and neutron scattering gives an excellent metrological support in the domain from 100 angstrom to 10 angstrom.
