The melting of crystals is the process by which an increase in temperature induces the disruption of the ordered crystalline ...

To understand the amorphous structure of glass, we need to look at the starting ... from silicon dioxide (SiO 2), or silica. Inside the crystal, each silicon atom is bonded to four oxygen atoms ...

This is the opposite of what happens in crystals, whose ordered structure ... clearly identify the topological defects in an amorphous colloidal glass created in the lab by randomly assembling ...

In that sense, polyamorphism is the amorphous analogue to polymorphism in crystals. Common to most ... report on polyamorphism in a metallic glass, where the bonding is non-directional in nature ...

and strongly reminiscent of the behaviour of glass-forming liquids. Understanding the formation of amorphous solids, such as glasses, colloids and granular materials, is a challenge. As with many ...
