Note: Nanomaterials can be defined as materials that have at least one external dimension with a size of 1 to 100 nanometers. And  particle size At least half of the particles in the number size distribution must be 100 nm or less. Nanomaterials can occur naturally, as by-products of combustion reactions, or can be purposefully engineered to perform a specific function. These materials can have different physical and chemical properties from their bulk prototypes.

Nanomaterials are used in combination with electrical voltage to bend in combination. The use of nanomaterials is common in a wide range of industries and consumer products . In nanoscience, the structure of materials determines the relationship between the atoms, ions, and molecules that make up those materials. To understand the structure of materials, one must first understand the type of bonds between atoms and ions . Chemical bonds determine how bonds between atoms and ions are made. Therefore, differences in the type of connections can be seen in the characteristics of these links. For example, in NaCl due to the presence of ion bonds that lead to the entrapment of electrons, (property Conductivity is not observed, because the electrons that carry the charge are unable to move due to confinement and there is nothing to transfer the charge between the material. Conversely, in metals, such as copper, conductivity can be expected due to the presence of a metal bond that  releases electrons and allows electrons to move. Because free electrons allow the transfer of electrical charge throughout matter. Knowing the type of atomic bonds can help to understand the behavior and properties of materials. 


If we shrink a material, the properties of that material become smaller and micrometer in size, for example the size of a particle of sand is almost the same as the original mass, but when that material reaches much smaller dimensions and the size of nanometers. The properties of matter change in such a way that the laws of ordinary and classical physics can no longer explain it. That material, for example gold in nanometer dimensions, may have properties such as electrical, optical, or mechanical properties that are very different from its bulk size.



Conclusion: 

Nanomaterials are used in combination with electrical voltage to bend in combination. The use of nanomaterials is common in a wide range of industries and consumer products  . In nanoscience, the structure of materials determines the relationship between the atoms, ions, and molecules that make up those materials.
