Abstract:
The samples were prepared within the binary system NaVO3-Co3O4 at different molar percentages depending on the ceramic method according to (x)NaVO3-(100-x)Co3O4, for the molar percentages (x = 5, 10, 25, 40, 60, 75, 80) mole%. The prepared samples were studied using X-rays diffraction (XRD), and their electrical properties were studied using LCR meter, such as the specific electrical resistivity ρ, electrical capacitance C, relative dielectric constant Ԑr, and loss tangent tanδ within the frequency range (10Hz-MHz). The results showed that the resistivity values of all the prepared samples increased, and the highest value is 2.91 × 10+07 (Ω.cm), in addition to the increase in the values of electrical capacitance and the highest value is 9.05 pF, the highest value of the relative dielectric constant is 28.39, and the highest value of the loss tangent is 7.01 × 10-2, with the change in the molar percentage of sodium meta vanadate in the samples.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Theory of Metallic Conduction
In this theory, Newton's second law of motion is used to determine the acceleration of an electron in the presence of an applied electric field. Then, its velocity is expressed via this acceleration.
An electron moves through the crystal, containing positive ions,...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
