Note: Many methods have been developed to produce "nano spin electrons" or nanostructured particles, which include vapor, liquid and solid state processes.
In general, chemical reactions to produce "nano spin electrons" can take place in any of the solid, liquid and gas states. The common method is to produce materials in a solid form, which increases the contact surface by crushing the particles, and further, to increase the penetration of atoms and ions, this mixture is increased at high temperatures.
"Nanospin electrons" refer to materials or structures that have at least one dimension between 1 and 100 nanometers . The importance of nanoscale is in changing the properties and characteristics of materials in these dimensions. Properties such as electrical conductivity, electromagnetic properties, etc. Starting to change the properties of the material by shrinking it depends above all on the type of material and the desired property. For example, by shrinking the dimensions of a material, generally some of the electromagnetic properties of nano-molecular materials such as the conductivity of nano particles in materials are improved. This increase in strength does not happen only in the range of a few nanometers, and the strength of materials of several tens or even hundreds of nanometers may be much higher than the mass material of a large scale. On the other hand, it is possible to change some properties such as conductivity in nanotransistors and electromagnetic properties in nanowires. It occurs in the dimensions of only a few nanometers.
In nanotechnology, two methods are considered for making "nano spin electrons" : the bottom-up method and the top-down method. In the bottom-up construction method, devices and materials are built from the molecular level based on the principles of molecular chemistry, just like a wall is built from brick by brick. In the top-down manufacturing method, "nano-spin electrons" are manufactured in larger quantities without atomic control, in this way, advanced equipment of this technology, such as atomic microscopes and scanning tunneling microscopes, are used in their manufacture, rather than the process of manipulation and creation of phenomena. and new properties appear in "Nanospin Electrons" . One of the important properties of "Nano Spin Electrons" is the high surface to volume ratio of these materials. Using this property, powerful catalysts can be produced in nanometer dimensions. These nanocatalysts will greatly increase the efficiency of chemical reactions and also significantly prevent the production of waste materials in "Nanospin Electrons" .
Conclusion:
Many methods have been developed to produce "nano-spin electrons" or nano-structured particles, including vapor, liquid and solid state processes.
