Metastability and instability of organic crystalline substances
Article Abstract:
A detailed analysis of thermodynamically paradoxical transition from a crystalline state to an amorphous dense glassy state induced in pure organic substances of pharmaceutical importance is reported. The transitiometric analysis of crystalline to amorphous transition with two polymorphs of rosiglitazone maleate could be used to study stability of crystalline components of drugs.

Structural relaxation and calorimetry in the glass-softening range of 1,3,5-tris(1-naphthyl)benzene
Article Abstract:
Results show that 1,3,5-tris(1-naphthyl)benzene samples on annealing and slow cooling are capable of increase or decrease in the glass width. Rapid cooling or heating abolishes this property.
