The influence of different types of nanoparticles on the dynamics of glass forming matrices has been studied by small oscillatory shear rheology. Experimental measurements reveal that besides the glass transition process of the matrix an additional relaxation process occurs in presence of nanoparticles. The latter is identified as the macroscopic signature of the microscopic temporal fluctuations of the intrinsic stress and is called Brownian relaxation. Besides the fact that Brownian relaxation has so far not been observed in colloidal suspensions with a matrix exhibiting viscoelastic behaviour in the frequency range of the experimental probe, the study reveals another important feature to be highlighted: the evolution of the Brownian rel...
