The bubbles that usually appear in the bulk of an adhesive film during separation allow for a significant deformation of the adhesive material and are therefore an essential ingredient for a high dissipation. Recent observations have shown that they appear in the early stages of separation. The present model describes the early deformations induced in the film by the bubbles, and predicts how many will appear, depending on the separation velocity and on the number of weak points in the film. The trends we obtain are in agreement with observations.

We study Seebeck effect in liquid electrolytes, starting from its simple neutral analog--thermodiffusion (so-called Ludwig-Soret or Soret effect). It is observed that when two or more subsystems of mobile particles are subjected to the temperature gradient, various types of them respond to it differently. In the case when these fractions, with different mobility parameters (Soret coefficients), are oppositely charged (a case typical for electrolytes), the nonhomogeneous internal electric field is generated. The latter field prevents these fractions from space separation and determines the intensity of the appearing Seebeck effect.
