Fragility crossover mediated by covalent-like electronic interactions in metallic liquids In the field of glass and liquid sciences, the so-called fragility is a key concept that characterizes how rapidly the liquid dynamics showdown on lowering the temperature. However, a long-standing challenge is that the occurrence of crystallization hinders the evaluation of fragility in glass-forming materials.
