Anomalous transport regime

The treatments at 300 ev, low and nediun doses, are also in the anomalous transport regime, whereas that at high dose is in the steady state regime. In addition, at this high dose, a thermal spike mechanism proposed for low ion energies, could induce a morphological modification, as shown in the IR spectra by diminished cis bands and increase in aromatic carbon (Fig. 7b) and also sustained by DTA and DSC curves (Figures 4 and 5. ... 

Let s consider the physical basis of the change of diffusion regime from slow (subdiffusive) up to rapid (superdiffusive). Anomalous (strange) transport processes are described by the general equation [8] ... 

Abstract Analytical solution of the associative mean spherical approximation (AMSA) and the modified version of the mean spherical approximation - the mass action law (MSA-MAL) approach for ion and ion-dipole models are used to revise the concept of ion association in the theory of electrolyte solutions. In the considered approach in contrast to the traditional one both free and associated ion electrostatic contributions are taken into account and therefore the revised version of ion association concept is correct for weak and strong regimes of ion association. It is shown that AMSA theory is more preferable for the description of thermodynamic properties while the modified version of the MSA-MAL theory is more useful for the description of electrical properties. The capabilities of the developed approaches are illustrated by the description of thermodynamic and transport properties of electrolyte solutions in weakly polar solvents. The proposed theory is applied to explain the anomalous properties of electrical double layer in a low temperature region and for the treatment of the effect of electrolyte on the rate of intramolecular electron transfer. The revised concept of ion association is also used to describe the concentration dependence of dielectric constant in electrolyte solutions. 

The finding of anomalous diffusion in gas transport through amorphous polymers by TSA was bom out completely by MD. For a favourable case of fast diffusion, MD could detect the crossover from short-time motion inside cavities to the anomalous diffusion, and then to the Einstein regime. Anomalous diffusion must be expected for all transport of light gases through amorphous polymers.
