Autowave processes of forming gels as a cause of the coloring of oxyhydrate gels (the chromatic effect) of some rare earth metals (yttrium, gadolinium)

The authors attempted to find common reasons and regularities of inorganic and organic biosystems gelation and the prime modeled representations of biosystems in the lifeless nature. With the help of a hydrodynamic model for the movement of colloid-chemical motion of elements in hydroxide gels of rare earth metals (yttrium, gadolinium) the fluctuating character of excited gelʹs behavior in a liquid media is shown. Account for the dipole–dipole interaction of gelʹs fragments in intermicellar solution allowed to prove mathematically the spiral shaped formation of a gel, which was certified experimentally. With the help of different methods of computer experiment, including a molecular-dynamic modeling of polymeric hydroxide excited media, the two-dimensional spiral-shaped formation of overmolecular fragments of yttrium, gadolinium gels, characteristic of autowave processes, is found. There are given details of spiral formed vortexes. The effect of coloring the oxyhydrate gels of some high-density metals (the chromatic effect), in particular, the rare earth elements of yttrium, gadolinium, lanthanum, and others were experimentally discovered. The periodic, oscillating nature of the change in the intensity of the gels color yttrium and gadolinium oxyhydrate over time has been demonstrated. Theoretical and calculation methods were developed to explain the effect of coloring the oxyhydrate gels of high-density metals.
