Optical studies of colloidal quantum dots : optical trapping with plasmonic nanoapertures and thermal recovery from photoinduced dimming
… thermal recovery was well described by a stretched exponential function, and further analysis yielded an underlying probability distribution of rate constants. Casting the rate constants as a collection of first-order activated processes provided an activation barrier probability …

Ensemble and single molecules fluorescence studies of polymers
… transition are analyzed and the correlation function of reduced linear dichroism is fit by a stretched exponential function. The fitting results suggest that non-exponential decay of correlation function. However, more rigorous study is needed because of the intrinsic statistical error of …

Nanoporous glass-ceramics transparent in infrared range to be used as optical sensor-Mechanical and viscoelastic properties of the TAS (Te-As-Se) glass
… properties have been investigated as a function of time and environment. From a general observation, air and vacuum have dramatic effects on TAS fibers tensile strength. When ageing under static stress, they exhibit an increase of tensile strength. The structural relaxation phenomenon is …

Dielectric relaxation behavior of poly(3-hydroxybutyrate)
… the majority of empirical dielectric relaxation functions has been reviewed including the Havriliak-Negami model and the Kohlrausch-Williams-Watts stretched exponential function. It was found that the center of relaxation time in the Havriliak-Negami model was skewed toward short time scale of …

Dynamics of nanoparticles in complex fluids.
… concentration and it can be fitted with a stretched exponential function. At high concentration of the polymer, a clear subdiffusive motion of the particles was observed. The results were compared with the diffusion of free dyes, which showed normal diffusive behavior for all …
