Glass formation/crystallization phenomena were studied in water and glycerol mixtures using adiabatic calorimetry. The sample was cooled rapidly from room temperature and its thermal response was followed on heating from 80 to 300K. The binary mixtures with the glycerol contents more than 55% (w/w) (19mol%) yielded the homogeneous glassy states, consisting of randomly mixed water and glycerol molecules...
Liquid methylhydrazine monohydrate (CH 3 NHNH 2 H 2 O; molar mass=0.06409 kg mol -1 ) can be easily quenched into a glassy state. On reheating, the glass transition occurs near 160 K (T g ) with an important heat capacity variation (ΔC p =96.8 J mol -1 K -1 ). This glass is extremely fragile according to Angell's...
