Metastable Systems under Pressure

recently discovered advantages of amorphous forms of medicines/pharmaceutical products which focused a significant part of industry-related efforts on the GFA (Glass Forming Ability) and the glass temperature (T) versus pressure g dependences. 1 b ? 0 ? ? o ?

Contains both review articles as well as novel results at the very cutting edge of the current science There is the first message on the universal onset of the complex dynamics in glasses, the validity of the picture "one liquid two glasses" for molecular liquids, novel VFT equation counterparts or surprising features of liquid crystals and nanoparticles are extremely hot issue for any specialist in the given field Also clearly interdisciplinary, since it contains a comprehensive presentation of papers ranging from various branches of the soft matter physic through biotechnological issues to environmental/geophysical/deep earth issue
