Note: Nanostructure is defined as any structure with one or more dimensions and is measured within the nanometer scale.
Nanostructures are materials or structures that have at least one dimension between 1 and 100 nanometers . The importance of nanoscale is in changing the properties and properties of materials in these dimensions. Properties such as electrical conductivity, electromagnetic properties and so on. Starting to change the properties of a material by shrinking it depends more than anything else on the type of material and the property in question. For example, as thedimensions of a materialshrink , some of the electro-magnetic properties of nanomolecular materials, such as the conductivity of nanoparticles in materials, generally improve. This increase in strengthdoes not occuronly in the range of a few nanometers, and the strength of a few tens or even one hundred nanometers may be much higher than a large mass. On the other hand, it is possible to change some properties such as conduction in nano-transistors and electromagnetic properties in nano-wires. It is only a few nanometers in size.
Self-aggregation (nanoparticles) in nanostructures is a spontaneous process by which nanoparticles / nano-phases are transformed into organized performance. Two important types of nanostructures are conductive nanoparticles (microstructure particles, often semiconductor materials) and CNTs nanotubes (fine tubes, usually pure carbon). Depending on the scale of their nanoparticles, the accumulative nanoparticles themselves change the nanostructures. CNT carbon nanotubes can transmit large amounts of electric current, much more than nanofibers and graphene nanotubes in general. And it becomes semiconductors.
Conclusion:
In describing nanostructures, it is necessary to distinguish between the number of dimensions in the volume of an object that is nanoscale . Nanostructured surfaces have a nanoscale dimension . Spherical nanoparticles have three dimensions , ie the magnifying glass of each of the spatial dimensions is between 0.1 and 100 nanometers. Self-aggregation terms are often used synonymously in nanostructures , although this function can also reach the micrometer range.
