Abstract :
Structural and thermodynamic changes in the organic molecular crystal of trehalose upon high energy ball milling have been studied. The investigations have been performed by X-ray diffraction and by differential scanning calorimetry. The results show that mechanical milling induces a direct transformation from crystal to glass. It is underlined that glassy amorphous trehalose can also be produced by two other independent routes: the thermal quench of the liquid state and the dehydration of the dihydrate form of trehalose. This makes trehalose a promising molecular crystal for the fundamental study of the solid state amorphization processes themselves.
