Note: An important feature of all nanostructures is that the number of surface atoms in them is greater than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, nanoparticle size is an important feature.
The range of activity of nanoparticles depends on the nature and shape of the nanostructure. With However, if the energy field of nano-particles with energy exposure to electro-magnetic analogy, and if within a certain wavelength, the occurrence of chemical reactions in materials under irradiation dramatic changes the activity of nanoparticles in the size of 100nm will be dramatic. Nanoparticle surface atoms are not energized. In general, the results of nanoparticle energy growth can be expressed as the total energy of the atoms on the surface of the particle. Freedom of movement of atoms at the surface of nanostructures is limited, and only vibrational and electron motions are possible. These two electromagnetic reactions are interdependent because the displacement of the electron clouds of atoms inevitably changes the vibrational frequencies of nanoparticle atomic bonds. Gives. On the other hand, the displacement of capacitance electrons in the bonds changes the bond polarity and the objects called the molecular cloud . In this case, the transfer of electrons to a higher energy level is possible. In this regard, CNTs carbon nanotubes are the most interesting species studied. They interact with the carbon nanotubes that protect them from the environment, which is why these CNTs are called metal / carbon nanotubes.
Fullerens are identified by the number of atoms in their structure. A letter C is used to name fullerenes, indicating the carbon atom in their structure. After the letter C, the number of carbon atoms in the Fullen spherical lattice unit is stated. For example, the C60 molecule has 60 carbon atoms. The number of atoms in the produced fluorines is from 28 to hundreds of carbon atoms
Conclusion:
An important feature of all nanostructures is that the number of surface atoms in them is greater than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, nanoparticle size is an important feature.
