Since carbon nanotubes are able to pass electric current through the ballistic transfer of electrons without friction from their surface-this current is a hundred times higher than the current that passes through a copper wire-the nanotube is an ideal choice for building nano memory cloud chips. Creating chipsNano memory cloud-Nano memory cloud is made of carbon nanotubes. Although the discovery of small carbon nanotubes has been very resistant, flexible, and conductive, with dimensions equal to DNA strands, and the use of small organic molecules to absorb charge instead of charge storage capacitors in nanotype memory chips. Nanocrystals, whose use causes The life span of nano memories to increase, is involved. Indeed, using nanotechnology, the storage capacity of information can be increased by a thousand times or more. Storing information is a very important and necessary topic that can be addressed in different ways through the cloud and nano memories. One of the new tools for storing information is the use of nickel quantum dots in nanometer sizes, which are expected to be used to store terabytes of data. According to cloud nano memories, there is high potential for activity in this field. The structure and design of supercapacitors based on nanoelectronics store 100 times more charge than electrolyte types in the same volume and are charged and discharged much faster than batteries.

This element belongs to the group of iron and cobalt elementsUsing particles from the microscale to the nanoscale provides benefits for various scientific fields, but because a large percentage of their atoms is on the surface, nanomaterials can be highly reactive and pose risks. have a potential for humans. Nanoparticles are of great interest due to their wide application, both in industry and in the natural sciences. While natural materials have constant physical properties regardless of size, the size of a nanoparticle determines its physical and chemical properties. Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant. The important feature of all nano structures is that in which the number of surface atoms is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature. The range of activity of nanoparticles 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 in a certain range a wavelength with the occurrence of chemical reactions in materials Under irradiation, significant changes will be made in the activity of nanoparticles up to 100 nm in size. is the nanometer expected to be used for storage. Given the relatively large (physically speaking) storage devices we have now and the fact that we need gigabyte sizes in various areas, there is a high potential for activity in this There is a context. Each quantum dot consists of a discrete ball of several hundred atoms that can have one of two magnetic states. This allows them to contain a single bit of information (zero or one), as is customary in machine computing. In conventional hard disks, the data bits must be spaced far enough apart that they do not overlap. Quantum dots act as completely independent units that are not structurally connected, so they can become somewhat closer to each other. One of the new information storage tools is the use of nickel quantum dots in nanometer sizes, which are expected to be used to store terabytes of data.

(60) fullerenes, which are also called buckyball and buckytube, include nanotubes, nanofibers, fullerene has a structure similar to graphite, but instead of completely hexagonal sections, carbon atoms are placed in the vertices of the 5th or 7th polygons. There are two types of connections in the structure of diamond nanographites: 1-Covalent bond, the connection between the carbon atoms of each honeycomb layer. 2-It is a connection that connects the layers of the honeycomb. Nano graphite, like honeycomb plates, has high strength due to having a strong covalent bond; On the contrary, this structure is much less strong than the honeycomb panels. The structure of diamond nanographite has a lattice structure. In nano-graphite, atomic bonds are established only on the surface, while in the diamond structure, these bonds fill the space in a three-dimensional network. In graphite, the carbon atom forms a covalent bond with three other carbon atoms, while in diamond, the carbon atom forms a covalent bond with four other carbon atoms. Applications of nano diamond in nano electronics industries in nanoelectronic industries; Nano chip, increasing the speed of nano transistors, both types of diamonds, i.e. n and p type stones, are used for nanoelectronic applications in microelectronics. He produced blue diamonds and by adding phosphorus to colorless diamonds, he also produced n-type diamonds. Today, many semiconductors such as silicon are used in a wide range of nanoelectronic devices. However, due to the range of thermal changes and its extremely high speed, nano diamond is only compared to gold nanoparticles, which holds the title of the second best nano semiconductor in the world.

Nanowires (SiNWs) have high mobility and surface-to-volume ratio, which makes them easy to control using a weak electric field. These one-dimensional nanostructures are created from nanowires with a diameter in the range of nanometers and a length of more than a micrometer. It has been done in the manufacture of nanowires through regular one-dimensional arrays with the help of different physical and chemical methods. Methods such as the use of electron beam or lithography method, heavy ion irradiation, laser, chemical and electrochemical methods such as water heat and spontaneous assembly methods used to make the membranes of molds can also be used. In making one-dimensional nanostructures such as Oligophenylene vanillin nanowires The electro-accumulation method consists of three general steps: firstly, the creation of a porous template as a suitable substrate and framework for the accumulation of nanowires, secondly, the growth of nanowires along the cavities of the template, and thirdly, removing the template and separating the nanowires from it. The nanowires are directly dependent on the characteristics of the mold surface such as the size distribution of the holes, the density of the holes and the superiority of the surface of the nano-holes. In order to control the properties of Oligophenylene vanillin nanowires, parameters that are effective in the formation and optimization of the diameter of the holes and the thickness of the mold should be considered.

Finds. An increase in the surface-to-volume ratio and changes in geometry and electronic structure have a strong impact on the chemical interactions of matter, and for example, the activity of small particles changes with changes in the number of atoms (and thus the size of the particles). Unlike today's nano-transistors, which behave based on the movement of a mass of electrons in matter, new devices follow the phenomena of quantum mechanics at the nano scale, in which the discrete nature of electrons cannot be ignored. By reducing all the horizontal and vertical dimensions of the transistor, the electric charge density increases in different areas of the nano-transistor , or in other words, the number of electric charges per unit area of the nano-transistor increases. This has two negative consequences: First, with the increase in electric charge density, the possibility of electric charge discharge from the insulating areas of the transistor increases , and this causes damage to the transistor and its failure. This event is similar to the discharge of excess electric charge between the cloud and the ground in the phenomenon of lightning, which causes the ionization of air molecules into negative and positive ions. Secondly , with the increase of the electric charge density, the electrons may leave the range of the radius of one atom and enter the range of the neighboring atom's radius under the influence of repulsive or abduction forces, which have now increased in value. This is called tunneling in quantum physics. Electron tunneling from one atom to the adjacent atom is a phenomenon that happens a lot between electrons in small dimensions. This phenomenon is the basis of the

In a multilayer graphene field effect nMOS transistor, the current between the two electrodes is controlled by the electric field from the third electrode. Unlike the bipolar transistor, it is capacitively connected to the third electrode and is not in contact with the semiconductor. Three electrodes in the structure of the nMOS graphene field effect transistor are connected to the source, drain and gate, and this action increases the switching speed (doping) in the nMOS graphene transistor circuit. [1][2] Graphene in nMOS field-effect transistors is an excellent electrical conductor, and also has outstanding spintronic properties. The ultra-thin carbon lattice is capable of transporting electrons with coordinated spin over longer distances and spinning for longer periods of time than any other known material at room temperature. Although the distance is still on the scale of a few micrometers and the time is still measured in nanoseconds, it essentially opens up the possibility of using rotation in microelectronic components.

Nanobots are generally divided into two categories: medical and military.Collaborative behaviors, that is, the cooperation of nanobots and their coordination in missions, sometimes the collective performance of nanobots has better results. Some nanobots must be able to assemble themselves automatically or reproduce like single-celled organisms, and also be able to repair themselves if damaged. Information planning and processing The processing of information collected from the biological environment and programming for nanobots is of particular importance. In addition to identification, these two types of nano-robots are also used in military applications.

In the presence of a certain molecule, the biological system changes the properties of the environment.
Note: In electrical conduction from a conductor to a semiconductor or an electrically changeable ... more Note: In electrical conduction from a conductor to a semiconductor or an electrically changeable insulator, nanotubes depend on their molecular chiral structure and angle. Since carbon nanotubes are able to pass electric current through the ballistic transfer of electrons without friction from their surface-this current is a hundred times higher than the current that passes through a copper wire-the nanotube is an ideal choice for building nano memory cloud chips. Creating chipsNano memory cloud-Nano memory cloud is made of carbon nanotubes. Although the discovery of small carbon nanotubes has been very resistant, flexible, and conductive, with dimensions equal to DNA strands, and the use of small organic molecules to absorb charge instead of charge storage capacitors in nanotype memory chips. Nanocrystals, whose use causes The life span of nano memories to increase, is involved. Indeed, using nanotechnology, the storage capacity of information can be increased by a thousand times or more. Storing information is a very important and necessary topic that can be addressed in different ways through the cloud and nano memories. One of the new tools for storing information is the use of nickel quantum dots in nanometer sizes, which are expected to be used to store terabytes of data. According to cloud nano memories, there is high potential for activity in this field. The structure and design of supercapacitors based on nanoelectronics store 100 times more charge than electrolyte types in the same volume and are charged and discharged much faster than batteries.

Finds. An increase in the surface-to-volume ratio and changes in geometry and electronic structure have a strong impact on the chemical interactions of matter, and for example, the activity of small particles changes with changes in the number of atoms (and thus the size of the particles). Unlike today's nano-transistors, which behave based on the movement of a mass of electrons in matter, new devices follow the phenomena of quantum mechanics at the nano scale, in which the discrete nature of electrons cannot be ignored. By reducing all the horizontal and vertical dimensions of the transistor, the electric charge density increases in different areas of the nano-transistor , or in other words, the number of electric charges per unit area of the nano-transistor increases. This has two negative consequences: First, with the increase in electric charge density, the possibility of electric charge discharge from the insulating areas of the transistor increases , and this causes damage to the transistor and its failure. This event is similar to the discharge of excess electric charge between the cloud and the ground in the phenomenon of lightning, which causes the ionization of air molecules into negative and positive ions. Secondly , with the increase of the electric charge density, the electrons may leave the range of the radius of one atom and enter the range of the neighboring atom's radius under the influence of repulsive or abduction forces, which have now increased in value. This is called tunneling in quantum physics. Electron tunneling from one atom to the adjacent atom is a phenomenon that happens a lot between electrons in small dimensions. This phenomenon is the basis of the

In a multilayer graphene field effect nMOS transistor, the current between the two electrodes is controlled by the electric field from the third electrode. Unlike the bipolar transistor, it is capacitively connected to the third electrode and is not in contact with the semiconductor. Three electrodes in the structure of the nMOS graphene field effect transistor are connected to the source, drain and gate, and this action increases the switching speed (doping) in the nMOS graphene transistor circuit. [1][2] Graphene in nMOS field-effect transistors is an excellent electrical conductor, and also has outstanding spintronic properties. The ultra-thin carbon lattice is capable of transporting electrons with coordinated spin over longer distances and spinning for longer periods of time than any other known material at room temperature. Although the distance is still on the scale of a few micrometers and the time is still measured in nanoseconds, it essentially opens up the possibility of using rotation in microelectronic components.

Nanobots are generally divided into two categories: medical and military.Collaborative behaviors, that is, the cooperation of nanobots and their coordination in missions, sometimes the collective performance of nanobots has better results. Some nanobots must be able to assemble themselves automatically or reproduce like single-celled organisms, and also be able to repair themselves if damaged. Information planning and processing The processing of information collected from the biological environment and programming for nanobots is of particular importance. In addition to identification, these two types of nano-robots are also used in military applications.
