Right down on a molecular level, water ice can form out of a rich variety of structures.
at very low temperatures. TEM uses beams of electrons and their reactions to image objects at molecular scales.
The ice that formed was primarily cubic ice, with a smaller amount of the more regular, hexagonal ice alongside it. That two ice phases formed might give scientists a clue as to why cubic ice hasn't shown up properly in past experiments, the team says.
As this experiment shows, cubic ice is more likely to form at very cold temperatures, far below what you'd manage with your home freezer. That means understanding it is crucial for the study of ice in the upper atmosphere, ice used for cryopreservation, and so on. The case isn't quite closed yet, and the researchers acknowledge that further investigations are required to confirm the existence and properties of cubic ice – including how its defects might influence its behavior.
"The examination of the structure and dynamics of defects in ice Ic provides a key step towards understanding the plasticity of ice at the molecular level,"
