Glass transition phenomena in D-xylose aqueous solutions: A broadband dielectric spectroscopy study

Abstract : Broadband dielectric measurements for D-xylose-water mixture with x w = 0.30 & 0.40, were performed in the frequency range of 10 mHz to 10 MHz and in the temperature range of 150 K to 260 K. Differential scanning calorimeter was also carried out to see the thermal behavior of this aqueous solutions. Two relaxation processes were observed, in addition to the contribution of dc conductivity in the low frequency side. The lower frequency process, the so-called primary relaxation process (process-I), is responsible for the glass transition (T g) whereas the faster one or high frequency process (designated as process-II) is due to the reorientational motion of the water molecules.
