Next Zero Nanomaterials (D1 :)
Materials that are nanometer in size in all three dimensions and have no freedom in any dimension. According to some categories, these nanostructures are also called nanoparticles. Factors affecting the properties of nanoparticles are the size and material of the particles. Nanoparticles have different applications in various industries such as automobiles (anti-scratch, anti-fog glass, durable elastics, etc. (medical), making new drugs, diagnosing the symptoms of diseases, etc. And sewage, electronics, military industries), etc. Nanoparticles can be made in different shapes depending on their application, such as spherical, elliptical, cubic, prismatic, columnar, etc. Nanoparticles may be composed of one component. Or they are a combination of several components of the material.Also nanoparticles can be pure or a combination of several different materials.
One-dimensional nanomaterials (D1 :)
One-dimensional nanomaterials have two dimensions at the nanoscale and one free dimension. Nanowires, nanorods, nanotubes, nanofibers are all one-dimensional nanostructured materials. Factors affecting the properties of one-dimensional nanostructures are their material and length to diameter ratio (d / L). The most important feature of one-dimensional metal nanostructures is their electrical conductivity along the wire axis. Nanowires have many applications in various fields such as making very small computers at very high speeds, making very small lasers, diagnosing diseases, magnetic memories, and so on. Nanowires can also be pure or a combination of several different materials.
Two-dimensional nanomaterials (D2 :)
These materials have two free dimensions and one dimension at the nanoscale. Materials with a nanoscale dimension mainly consist of thin films or surface coatings. Factors influencing the properties of nanocoatings are their material and thickness. For example, cellophane holders are a type of cover. Now if their thickness is in nano dimensions, they are called nano coating. Nanocoatings are layers with a thickness of 0 to 011 nanometers that are placed as a coating on other materials and change their properties and characteristics. Thin layers can also be pure or a combination of several different materials.
Three-dimensional nanomaterials (D3 :)
That is, all three dimensions are on a free scale. This definition contradicts the definition of nanostructured materials, because none of its three dimensions are at the nanoscale. This category includes nanocomposites (composite materials that contain several materials (and bulk nanostructured materials) or bulk nanostructured materials (bulky nanostructured materials) are materials whose individual building units are at least less than 011 nanometers in size in one dimension. Some materials do not have a number of properties, for example plastic does not have electrical conductivity, but if we add a material such as fuzzy particles that have conductive properties, the resulting mixture can be conductive. The composite may be composed of more than two materials, each of which may have the ability to enhance one of its properties.If at least one of the components of the composite is nanostructured, it is called nanocomposite. For example, the conductivity of polymers can be increased by using carbon nanotubes.
Conclusion :
Every object and matter created in the mortal world has different physical dimensions; Chemical; Structural; This is important in nanoscience, especially nanoelectronics, to create new nanoporuos devices and nanomaterials.
