Interfacial ionic conduction

[DPSingh]

Is it possible to determine using impedance spectroscopy, if there is any interfacial ionic conduction or effect of interfacial ionic conduction on total ionic conductivity in a two phase mixture of a solid glass electrolyte and an insulating nano sized phase? Just like in polycrystalline ceramics, where we can separate grain and grain boundary conduction (presence of two semicircles)?
