Note: " Nanostructures " means a natural, accidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where for 50% or more of the particles in the number size distribution, one or more external dimensions are in the size range 1 - 100 nm. In special cases and where, the threshold of the size distribution may be replaced by a threshold between the particles of the nanomaterial.
Inferring from the above, nanostructures with one or more external dimensions less than 1 nm should be considered as vital devices in nanoelectronics. Nanostructures that react naturally. Or are produced as a combustion by-product (unintentional) from combustion processes. They are usually physically and chemically heterogeneous and are often referred to as porous particles. " On the other hand, nanostructures that are made of multiple structures with physical and electronic objectives are produced and designed for a specific purpose or function.
The important feature of all nanostructures is summarized in the fact that the number of atoms (surface) in them is greater than the number of atoms (volume). This ratio increases with decreasing size (nanoparticle). Therefore, the size of the nanoparticle is considered its important feature. The shapes and sizes of nanostructures are naturally determined based on their composition and conditions of formation. The characteristics of nanostructures, in turn, determine the originality of the characteristics of the nanostructure and the possible fields of their function. The range of 1 to 1000nm is introduced as the range of nanostructures, and an important feature of nanostructures is the control of the processes of their organization. The range of change in the activity of the nanostructure depends on the nature and shape of the nanostructure. However, if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if significant changes are made in a certain wavelength range with the occurrence of chemical reactions in the materials under irradiation, the activity of nanoparticles will be significant up to the size of 100nm. This increase in strength does not only occur in the range of a few nanometers, and the strength of a material of several tens or even hundreds of nanometers may be much greater than that of a large-scale bulk material. On the other hand, changes in some properties such as color and magnetic properties may occur in dimensions of only a few nanometers.In electronic science, the topic of nano is centered around (nano memories; nanochips and fast nanochips and nanoelectronic components) with less weight and greater efficiency. Nanotechnology is science, engineering and technology at the nanoscale, or in other words, the study of the application of very small objects and their use in all fields of science such as chemistry, biology, electronics; materials science and engineering.The history of nanotechnology describes the development of concepts and experimental work carried out in the field of nanotechnology. Although nanotechnology is one of the recent advances in scientific research, the development of its fundamental concepts has occurred over a long period.
Conclusion:
" Nanostructures " means a natural, accidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where for 50% or more of the particles in the number size distribution, one or more external dimensions are in the size range 1 - 100 nm. In special cases and where, the threshold of the size distribution may be replaced by a threshold between the particles of the nanomaterial.
