The researchers noted that, unlike most other materials, ice particles at very low temperatures
“In a perfectly ordered piece of ice, atomsThe hydrogen of each water molecule must point in one direction, it can be compared to a company of soldiers. Instead, water molecules in ice, even at very low temperatures, can look in different directions, ”the scientists noted.

The researchers explained this behavior of moleculesimpurities - as soon as they enter the initial nonequilibrium low-temperature state, they affect the molecules that are in front of and behind them. This extremely atypical process has many characteristics that can explain the incomplete onset of ferroelectric order in ice.
“Our research is still limited to smallamount of ice, but this mechanism seems to apply to all molecules. In particular, this explains the long-known small local ferroelectric polarization, a phenomenon related to the agglomeration of ice particles in interstellar space, ”the researchers noted.
