Fragility is a key property of liquids - in particular glass-forming liquids - characterizing the rapidity of change of their dynamical properties when cooled near the glass transition. Given the diversity of glass-forming substances and their properties, fragility serves as an important organizing principle. Since the time the concept was introduced and extensively studied by C. Austen Angell, a leading authority on many aspects of liquid-state science in the mid 1980s, thousands of papers have been published analysing fragility in a variety of liquids, extending and probing the basic...
