Probe Mössbauer diagnostics of dynamic properties of frozen water layers in montmorillonite pores

A methodical approach has been developed and tested on the basis of Mössbauer spectroscopy, which allows one to effectively estimate the viscosity of a medium based on the measured diffusion coefficient of a probe in thin films of bound water in a clay mineral. The procedure for reconstructing a specific type of potential is based on the analysis of viscosity coefficients and ion mobility measurement data related to diffusion by the Einstein relation. The experimental results fill in the missing information relevant for constructing a theoretical model for the formation of natural nanotubes.
