Density Scaling in Ionic Glass Formers Controlled by Grotthuss Conduction

We present investigations of the charge transport in an ionic glass-former carvedilol dihydrogen phosphate (CP) at various T- P- V thermodynamic conditions in terms of density scaling concept. The studied material was found to reveal superprotonic properties both at ambient and elevated pressure, as proved by the Walden rule. Surprisingly, from the isobaric conductivity data, the relaxation times τ
