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

And because of ice's innate crystal structure, it tends to break along straight lines. Dr. Jan Lieser: The icebergs that we usually see are weathered. They get beaten up by winds and waves and ...

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 ...

the spaces between ice crystals are filled with liquid water. To visualize the changes in the ice structure, the researchers employed aberration-corrected transmission electron microscopy ...
