Origin of the Dual Structural Transformation of Trehalose Dihydrate

12.09.2003Dehydration, Differential scanning calorimetry, Abstract Upon dehydration, trehalose dihydrate transforms either toward a glassy amorphous state or toward a polymorphic crystalline phase depending on the dehydration protocol. Although this duality is now admitted, its origin remains an open question.

Investigation of the Milling

18.05.2010Milling of griseofulvin results in the formation of an amorphous form and not a mesophase. It increases the amount of surface created and the overall energy of the amorphous griseofulvin, which leads to a decreased temperature of crystallization. The two exotherms in the DSC are due to some particles having nuclei on the surface. INTRODUCTION

Effect of trehalose on protein structure

Transformation path of trehalose forms. Dihydrate trehalose T h is formed at equilibrium from the solution state and can be transformed reversibly to T α. In addition, depending on the temperature and rate of water loss, T h can give either an amorphous form or the T γ form. Reprinted from Ref. 54, with permission from Elsevier.
