Note: In order to study the electromagnetic properties of nanowires, it is necessary to produce nanowires of uniform diameter and specific length.
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. Changing the Sr / Fe ratio does not change the morphology of the nanowires. And spectroscopy of nanowires with a ratio of Sr / Fe states within the nano-particles inside (nanowires uniform) elements Fe and Sr of ferrite strontium in spectroscopy nanowires uniform is seen in the sample of nanoparticles Sr / Fe to value Its stoichiometry is closer to the electromagnetic composition of nanoparticles, while Due to the lower solubility of uniform strontium nanowire nanomolecules compared to iron nitrate and the consequent presence of less strontium ions in the reaction with the electromagnetic particles of the nanowires, there is a greater amount of Fe ion in the final structure.
Electro-magnetically active particles are used to separate uniform nanowires at ambient temperature . In the application of nanowires in nanoscale electronics or some other applications, it is necessary to separate the nanowires from alumina particles . It is also necessary to separate the uniform nano-wires for better nano-electrostatic studies. In the application of uniform ferrite nanowires as microwave absorbers, it is not necessary to separate the nanowires from the inactive electromagnetic nanoparticles because the presence of an electrode material in the absorption of the ripple wave.
Conclusion :
Electron nanoparticles in nanowires and nanotubes separated from active nano-electromagnetic molecules and smooth and uniform nanowires with high specific length (ratio to length to diameter) are well known; The nanowires with a smooth and uniform surface with electro-magnetic properties compared to conventional nanowires formed.
