We shall adopt a physical model in which the adsorben! surface and the properties of each of the layers are uniform. Full allowance is made for interactions within each layer. This interaction gives rise to the phase transition within the layer. Allowance for the interaction between layers is made through the dimensional defect of chemical potential.

The investigation of the phenomenon of intergranular segregation in solids is a very important area of ​​materials science. This phenomenon plays an active role in modifying the various properties that have materials, which are very important for many industries (the adhesion of thin films in the electronics industry, fatigue and stress corrosion of metals, etc. .). We present a statistical thermodynamic treatment of the phenomenon of intergranular segregation consisting of one and two component systems.

The decomposition of hydrogen peroxide H2O2, is a simple reaction to study the effect of the magnetic field in chemical reactivity. Hydrogen peroxide when dissolved in water is decomposed into oxygen and water slowly. In the absence of a catalyst, the reaction is extremely slow. We have studied the effect of the magnetic field in the synthesis of Fe3O4 and catalytic decomposition of H2O2 by Fe3O4 also propose a theoretical treatment of the magnetic field effect on chemical reactions. The results show that magnetite, synthesized within the magnetic field is more reactive than the synthesized outside the magnetic field.
