The dynamics of an interface plasma-plasma self-structured as a double anodic layer using the fractal space-time theory is established. So, for the fractal dimension D = 2, the Schrödinger "fluid" is obtained as an irrotational movement of a Navier-Stokes fluid with an imaginary viscosity coefficient. In the deterministic case, the anodic double layer is described by a set of diffusion-reaction equations, a situation in which the equal diffusion curves are of the Koch-type and the self-structuring is given by means of the coherence of the electron-ion pairs. In the nondeterministic case, the anodic double layer is described by a set of time-dependent Schrödinger-type equations and the self-structuring is given by means of the negative differential resistance and the pulsation-potential linear dependence. Through the spontaneous symmetry breaking the Langmuir's relations, the distributions of the potential field and charge densities have been obtained. The model was verified by means of our experimental data too.

An ionic diol bearing a one-sided urethane-stilbene group located on the ammonium quaternary structure was prepared and proposed as an intermediate for polyurethane ionomer synthesis. Polyurethane cationomers with stilbene ionic groups based on poly(tetramethylene oxide) diols, 4,4Ј-diphenylmethane diisocyanate and the aforementioned ionic diol, were synthesized and characterized. Some aspects of the trans-cis photoisomerism and fluorescent emission of the stilbene chromophore in polyurethane cationomers were studied comparatively with the urethane-stilbene diol. The stilbene polycations absorbed at A ϭ 316 nm and emitted violet-blue light with an emission maxima at F ϭ 444 nm (dimethylformamide solution) and F ϭ 465 nm (film). These polymers are known for their elastomeric properties and are assumed to be of great interest for some future applications.

The anodic double layer is studied by electrical methods. Irradiating this layer with an optical electromagnetic radiation, resulted in current intensity oscillations and also an increase in their amplitude. A theoretical model is described on the basis of a nonlinear diffusion equation, and both double layer diameter and characteristic oscillation time were calculated. Theoretical results are in agreement with experimental results.

Experimental results regarding the study of plasma double layers (DLs) by electric and spectral methods in the case of a glow discharge obtained in a chamber of three-electrode geometry are presented. The experimental results prove that the appearance of DLs in active plasmas can be accompanied by quantum processes, such as excitation and ionization.
