Effect of the film thickness on the effective electron-electron interaction in a metal film

An effective electron-electron interaction potential in a metal film is numerically calculated within the jellium model.   The effect of the film thickness on this potential is studied and it is found that even minor changes in the film thickness cause significant changes in the behavior of this potential.

Phenomenological Coefficients of the Viscosity for Low-Molecular Elementary Liquids and Solutions

The shear forces and corresponding strains appearing in the flow under the action of chemical potential gradient have been analyzed. The ratios for determination of the viscosity coefficient for low-molecular pure liquids and solution components were established. It was proved that the viscosity of the low-molecular solution can be expressed via the terms of the viscosity coefficients of its components and via their concentration.
