The eigenfrequencies of solvation shell oscillations with respect to the ion are estimated in various approximations describing the ion–solvation shell system. The results of comparisonwith experiments suggest that the most appropriate is the model

As a result of considering the interaction of an external electric field with free and bound charges that are in the volume of the salt solution in a polar dielectric fluid, an equation is obtained that describes the oscillations of an ion with respe

Single gas centrifuge (GC) is generally used for the separation of binary mixtures of isotopes. Processes taking place within the centrifuge are complex and non-linear. Their characteristics can change over time with long-term operation due to wear o

The paper studies the processes occurring in low-temperature plasma in the magnetic field. It shows that the laser excitation of molecular oxygen can increase the fraction of singlet pairs formed as a result of collisions between oxygen and carbon mo
