For the first time, scientists have watched metal crystals take shape inside a pool of molten metal, capturing a process that usually unfolds out of sight in the heart of furnaces and casting lines.

Many substances display crystallization, allowing them to keep adding to a basic shape to reach pretty humongous proportions.

Researchers captured real-time images of monolayer two-dimensional semiconductors growing inside a microreactor, revealing how molten precursor droplets drive crystal formation at the atomic scale.
