abstract = {We studied the thermal diffusion behavior for binary
aqueous solutions of glucose, maltotriose, maltohexaose,
pullulan, and dextran by means of thermal diffusion forced
Rayleigh scattering (TDFRS). The investigated saccharides
with molar masses between 0.180 and 440 kg mol(-1) were
studied in the temperature range between 15 and 55 °C. The
thermal diffusion coefficient D(T) and the Soret coefficient
S(T) of all solutions increase with increasing temperature.
For maltohexaose and the polymers the thermal diffusion
coefficient changes sign from negative to positive with
increasing temperature, whereas glucose and maltotriose show
only positive values in the entire investigated temperature
range. While we were able to find a master curve to describe
the temperature dependence of D(T), we were not able to find
a similar expression for S(T). This comprehensive study
allows for the first time the determination of the
interaction parameters for the polymer and the solvent
within the theoretical framework suggested by Würger [Phys.
Rev. Lett., 2009, 102, 078302].},
