Uniform nanowires are found in spectroscopy. In the sample, the ratio of Sr / Fe nanoparticles is closer to its stoichiometric value in the electromagnetic composition of nanoparticles, while due to the lower solubility of uniform nanotubes of strontium nanowires to iron nitrate. As a result, the lower the presence of strontium ions in the reaction with the electromagnetic particles of the nanowires, the greater the amount of Fe ions in the final structure. Electrically magnetic active particles are used to separate uniform nanowires at ambient temperature .
In general, in order to study the electromagnetic properties of nanowires, it is necessary to produce nanowires of uniform diameter and length. Nanowires are less than 100 nanometers in diameter and can be as small as 3 nanometers. Typically, nanowires are more than 1000 times larger in diameter. This huge difference in length-to-diameter ratio with respect to nanowires is often referred to as 1-dimensional materials. This leads to unique properties not seen in bulk materials, the minute size of nanowires means that quantum mechanical effects are of great importance. "Quantum wires" use quantum mechanics to produce wires with a wide range of unique electrical properties. These properties include quantum tunnels that have a very high conductivity to wires made of carbon nanotubes with electrons passing through the wire ballistically.
In the immersion method, nanowires have enough time to transfer from nanoparticle particles to cavities ; The formation step of uniform nanoparticles is done slowly and finally uniform nanowires are formed. Structural study with FESEM in the immersion method of single-stranded nanowires in all porosities and in a large area of nanowire particles are formed. The simple answer to this question is that each particle is less than 100 nanometers. But like a scale of 1 - 100 nm, the amplitude determines the size of a nanoparticle. In order to prevent contact of cluster particles from atoms, less than 1 nm may be removed, but the movement of electrons in nanoparticles to particles is <1 nm. Because the particles are three-dimensional.
Conclusion :
