C60) and Crucial Structure (Nanoparticles) in CNTs and CNTs (Based on Nano-Microelectronics PhD) (Educational-Research Ph.D.)
Researcher and author: PhD student Afshin Rashid
Note: Buckwheels are hollow, bulletproof carbon structures, the most popular being C60 or Fulleren. The C60 is similar to a soccer ball. The carbon atoms are joined by covalent bonds in a hexagon and a hexagon.
C60s or fullerenes are actually made up of 30 parts of which 10 are hexagonal and 12 are hexagonal. Buckwheat has many applications due to its chemical properties and its hollow and cage shape. Buckwheels are extremely stable and can withstand very high pressures and temperatures. The carbon atoms of the wingspan can react with atoms and molecules without altering their stability or spherical structure.
Nuclear structure (nanoparticles) in CNTs CNTs
Carbon nanotubes are one of the most important and widely used carbon structures. They have unique properties and characteristics. Carbon nanotubes not only have high strength, but also have good flexibility and flexibility. One of their applications is composite. The most important property of nanotubes is their electrical conductivity, which varies depending on the order of the atoms. They are cylindrical molecules with open or closed ends. The structure of the nanotubes is like a sheet of graphite that has been rolled. To better understand the structure of the nanotube, consider a graphite layer. Atoms in a row with (m, n) representing the coordinates of a point on the plane. So that the coordinates of n are the column of atoms and the coordinates of m are the rows of atoms. As we know, to make a tube from one plate, just place one point on the other. A nanotube is like a graphite plate shaped like a tube. Depending on how the two ends of the graphite plate are interconnected, we will have different types of nanotubes.
Zigzag type of nanotube
To make the zigzag type of nanotubes, we adapt the atoms (1 ) and 0 (0) to (horizontally) from column (columns) to columns (1 and 5) by bending the plate on the elementary atoms (1 and 1). To make sure the construction method is correct, we have to look at the horizontal end of a broken zigzag line around the nanotube.
Nano tube chair type
Seat-type nanotubes can be obtained if the elementary atoms and the atoms at 05 ° are aligned. In this case we can draw a straight line between these two atoms whose equation is 'n = m'. That is, the number of columns and rows are equal to each other. In this case, once we turn around the nanotube, we will see some seats in succession.
Asymmetric type of nanotubes
In this case, we will do the same as the chair method, except that the coordinates of the end atom will be n ≠ m. If we rotate horizontally around the nanotube, we see a set of chairs that are oblique to the horizon. To make a model of each type of nanotube, just bend the paper and match the endpoint to the starting point.
Conclusion :
Each of the three types of nanotubes has properties because of their atomic arrangement. Nanotubes have strong bonds between their atoms and therefore exhibit high strength and tensile strength . For example, the force required to break a carbon nanotube is as much as the force required to break a piece of steel with a thickness equivalent to one nanotube. The interatomic bonds in the nanotubes, in addition to providing high strength, allow for easy molding and even torsion, while the steel is only resistant to tensile forces and does not have the flexibility to twist .
