Nano Uranium (solid phase)

Note: Uranium, which is a heavy, toxic, metallic, radioactive element  and shiny with a silvery-white color, belongs to the group of actinides, and its isotope 235 is for The fuel of nuclear reactors  is used. Uranium is a silvery-white metal with weak radioactive properties when refined. a>  is softer. This metal is a thorn hammer, conducts electricity and is slightly paramagnetic.

The density of uranium is 65% higher than the density of lead. If the uranium is separated well, it is strongly affected by cold water and oxidizes against the air. Uranium extracted from mines can be chemically transformed into uranium dioxide and other species that can be used in industry. The use of particles from the micro scale to the nano scale has advantages for various fields. provides science, but since a large percentage of their atoms are on the surface, nanomaterials can react a lot and bring potential risks to humans.Nano Particles are of great interest in both industry and natural sciences due to their wide application. While natural materials have constant physical properties regardless of size, the size of a nano particle determines its physical and chemical properties. Therefore, the properties of a material change as its size approaches the nanoscale and the percentage of atoms on the surface of the material becomes significant.The important feature of all nano The structures are those in which the number of surface atoms is more than the number of volume atoms. This ratio increases with decreasing nanoparticle size. Therefore, the size of the nanoparticle is considered its most important feature.The range of activity of nanoparticles depends on the nature and shape of the nanostructure. With However, if the energy of the nanoparticle field is comparable to the energy of electromagnetic radiation and if within a certain range of wavelength with the occurrence of chemical reactions in materials Under irradiation, significant changes will be made, the activity of nanoparticles up to 100 nm will be significant.

The surface atoms of nanoparticles are not compensated in terms of energy. In general, the results of nanoparticle energy growth can be expressed as the total energy of atoms on the surface of the particle. The freedom of movement of atoms on the surface of nanostructures is limited and only vibrational movements and the movement of electrons are possible. These two electrokinetic reactions are dependent on each other because the displacement of electron clouds of atoms definitely changes the vibrational frequencies of the bonds of nanoparticle atoms. On the other hand, changing the location of valence electrons in the bonds changes the polarity of the bond and the objects known as supermolecule . In this case, electron transfer to a higher energy level becomes possible.

Conclusion :

Uranium extracted from mines can be chemically transformed into uranium dioxide and other species that can be used in industry.Using particles from the micro scale to the nano scale has advantages. provides for different scientific fields, but since a large percentage of their atoms are on the surface, nanomaterials can react a lot and bring potential risks to humans.< a i=2> Nanoparticles are of great interest due to their wide application, both in industry and in natural sciences.
