In ice, water molecules are arranged in a repeating pattern that gives ice its crystal structure. Even though ice is at 0 °C, the molecules still vibrate. After freezing, the water molecules are ...

High-pressure experiments generated the first direct observation of plastic ice, which has qualities of both crystalline ice and liquid water.

MIT physicists have made an exciting discovery: in an ultra-thin material, electrons can form crystal-like structures, acting like tiny frozen blocks of energy. This unexpected finding adds to a ...
