Progress in the physics of disordered media—that is, in the physics of media with a random distribution of microheterogeneity—is mainly made via the solution of problems involving the connection between the microscopic structure and the macroscopic behavior. This problem properly belongs to the realm of the kinetic theory of matter and is analogous to the problem of locking in the theory of fluids, hydrodynamic turbulence, the theory of phase transitions, and so on.

The optimization of metal electrodeposition in terms of reaction rate of metal removal is obtained under conditions of limiting current (iL). Hence, according to Eq. 1, the best values of 1l are obtained maximizing the mass transfer coefficient (km) and the electrode area (A) [16, 24]. These are the main reasons why three-dimensional electrodes are recommended for cathodic reduction of metals from dilute solutions, since electrode area is enhanced due to the use of the electrode volume kn, is improved by the hydrodynamic turbulence provided by the three-dimensional matrix [25]. A number of cell designs were developed in order to obtain high km, many of them mentioned in Fig. 1.

Thus, it appeared naturally to assume that every interesting dynamical regime possesses a discrete frequency spectrum. In this connection, it is curious to note that Landau and Hopf had proposed quasiperiodic motions with a sufficiently large number of independent frequencies as the mathematical image of hydrodynamical turbulence (the number of the frequencies was supposed to increase to infinity as some structural parameter, such as the Reynolds number, increases).
