Query: Fractional Debye-Stokes-Einstein behaviour in an ultraviscous
  nanocolloid: glycerol and silver nanoparticles   One of hallmark features of glass forming ultraviscous liquids is the
decoupling between translational and orientational dynamics. This report
presents studies of this phenomenon in glycerol, a canonical molecular glass
former, heading for the impact of two exogenic factors: high pressures up to
extreme 1.5 GPa and silver (Ag) nanoparticles (NP). The analysis is focused on
the fractional Debye-Stokes-Einstein (FDSE) relation $\sigma(T,P)*(\tau(T,P))^S
= const$, linking DC electric conductivity $(\sigma)$ and primary $(\alpha)$
relaxation time $(\tau_\alpha)$. In glycerol and its nanocolloid (glycerol with
Ag-NP) under atmospheric pressure only the negligible decoupling $(S = 1)$ was
detected. However, in the compressed nanocolloid a well-defined transformation
(at P = 1.2 GPa) from $S \thickapprox 1$ to the very strongly decoupled
dynamics $(S \thickapprox 0.5)$ occurred. For comparison, in pressurized 'pure'
glycerol the stretched shift from $S \thickapprox 1$ to $S \thickapprox 0.7$
took place. This report presents also the general discussion of FDSE behavior
in ultraviscous liquids, including the new link between FDSE exponent,
fragility and the apparent activation enthalpy and volume.
