Note: Nanostructures are defined as any structure with one or more dimensions and are measured in the nanometer scale range.
Nanostructures are materials or structures that have at least one dimension between 1 and 100 nanometers . The importance of nanoscale in changing the properties and characteristics of materials in these dimensions. Properties such as electrical conductivity, electromagnetic properties and so on. The beginning of changing the properties of a material by shrinking it depends more than anything on the type of material and the desired property. For example, as thedimensions of a materialshrink , some of the nanomolecular electromagnetic properties of 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 materials of several tens or even hundreds of nanometers may be much greater than that of large-scale bulk material. On the other hand, it is possible to change some properties such as conductivity in nanotransistors and electromagnetic properties in nanowires. It occurs in dimensions of only a few nanometers.
Self-aggregation (nanoparticles) in nanostructures is a spontaneous process by which nanomolecules / nanophases become organized function. Two important types of nanostructures are conductive nanoparticles (microstructures, often semiconductors) and CNTs ( nanotubes , usually made of pure carbon). Self-aggregating nanoparticles made of semiconductors change nanostructures depending on their scale. Carbon Nanotubes CNT can large amounts of electric current to pass, much more than nanowires and nano strips of graphene their overall aggregated in nano-structures to increase the interaction of nano-electromagnetic (nanoparticles) in nano conductive material And it becomes semiconductors.
Conclusion:
In describing nanostructures, it is necessary between the number of dimensions in the nanoscale size of an object is to distinguish. The surfaces of nanostructures have a dimension at the nanoscale. Spherical nanoparticles at the nanoscale have three dimensions , meaning that the magnifying glass of each spatial dimension is between 0.1 and 100 nanometers. Self-aggregation terms are often used synonymously in nanostructures , although this function can reach as far as the micrometer range.
