The mean diffusion coefficients, D, for maltose-water mixtures close to the glass transition temperature, Tg, were measured using a gravimetric method during desorption of water. The mass loss showed a linear dependence on the square root of time, indicating a Fickian diffusive process. At 300 K, an
The objective of the present work is to determine if crystallization onset observed for an amorphous solid correlate with relaxation time at temperatures above and below the calorimetric glass transition (T g ). Crystallization onset of spray-dried and freeze-dried amorphous sucrose were measured ca
