abstract = {We present the relaxation dynamics of glass-forming
glycerol mixed with 1.1 nm sized polyhedral oligomeric
silsesquioxane (POSS) molecules using dielectric
spectroscopy (DS) and two different neutron scattering (NS)
techniques. Both, the reorientational dynamics as measured
by DS and the density fluctuations detected by NS reveal a
broadening of the α relaxation when POSS molecules are
added. Moreover, we find a significant slowing down of the
α-relaxation time. These effects are in accord with the
heterogeneity scenario considered for the dynamics of
glasses and supercooled liquids. The addition of POSS also
affects the excess wing in glycerol arising from a secondary
relaxation process, which seems to exhibit a dramatic
increase in relative strength compared to the α
relaxation.},
