Probing ion dynamics in a clay-water system with dielectric spectroscopySamec, Marko (Avtor) Korošak, Dean (Avtor) Cvikl, Bruno (Avtor) , Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru (Lastnik avtorskih pravic) soil mechanicsdielectric spectroscopyporous materialconductivityfractional dynamicsDielectric spectroscopy characterization of clay-water mixtures is presented and the obtained spectra are analysed. A theoretical model for ion dynamics isproposed in which motion of ions in pore space electrolyte is interrupted by trapping events at the mineral surfaces. The typical time scales for these processes are given in terms of the physical properties of the material. It isshown that the microscopic motion of the ions in a complex environment of clay-water system can be described with fractional dynamics leading to subdiffusive behavior.20072018-05-18 09:44:24Znanstveno delo70518slFakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru
