“…The choice of this size range is not accidental but is determined by a number of size effects and the coincidence of the crystallite sizes with the characteristic sizes for various physical phenomena. The lower limit is related to the lower limit of symmetry of the nanocrystalline material [53][54][55]. The point is that as the size of the crystal, which is characterized by a strict set of symmetry elements, decreases, a moment comes when some symmetry elements will be lost.…”

“…According to [54,55], for the most widespread crystals with a bcc and fcc lattice, this critical size equals three coordination spheres, which for iron is about 0.5 nm, and for nickel, it is about 0.6 nm. The value of the upper limit is due to the fact that noticeable and interesting from a technical point of view, changes in the physical and mechanical properties of materials (strength, hardness, coercive force, etc.)…”

According to the estimates of many authors, in 10-15 years, the world market for nanotechnology products will amount to about 1 trillion $. The share of nanomaterials, in this case, is very large (about 340 billion). Therefore, research on nanomaterials properties becomes one of the most important tasks of the science of nanostructured materials. In this regard, it will be essential to expand research on the influence of size and thermal stability; as two common problems for almost all types of nanomaterials. This review article will discuss the most popular topics on nanomaterials, nanostructures, their history, characteristics and classification as well as status of their scientific articles published in recent years. This study focuses on a range of topics related to the development, research and manufacturing applications of nanomaterials and nanotechnology. There are many problems and challenges that scientists are investigating on them. For example: what are the main differences between the properties of interfaces of nanomaterials (including hybrid ones) from the characteristics of ordinary bulk states? How widely can the self-assembly technique of nanoscale devices elements be developed, considering possible installation errors?
