Abstract
Glasses are amorphous materials that lack the periodicity of crystalline substances. Structurally, they resemble metastable supercooled liquids but behave mechanically like solids. A typical way of preparing glass is by cooling a viscous supercooled liquid fast enough to avoid crystallization. Although this way of preparation is known for several thousands of years, the underlying molecular mechanism is not fully understood (Debenedetti PG, Metastable liquids. Concepts and principles. Princeton University Press, Princeton, 1996; Debenedetti PG, Stillinger FH, Supercooled liquids and the glass transition. Nature (Lond) 410:259–267, 2001).
