just as water changes from solid ice to liquid or steam with temperature change. Constructed from 1 billion tiny magnets,

A similar process can be observed in water molecules as water freezes into ice. Laura Heyderman

The team calls this a"highly degenerate spin ice phase (Ice I)".But then they started to slowly cool the material down,

This is classified as the"charge-ordered phase (Ice II"."Cooled down even further, and the magnetic arrangement appeared to undergo another change-it was frozen almost, just like water.

#Tiny magnets mimic steam, water and ice A synthetic material--created from 1 billion nanomagnets--assumes different aggregate states depending on the temperature:

the so-called metamaterial exhibits phase transitions, much like those between steam, water and ice. This effect was observed by a team of researchers headed by Laura Heyderman from PSI."

The long-range order of water molecules increases in a similar way at the moment when water freezes into ice.""We were fascinated by the fact that our synthetic material displayed this everyday phenomenon of a phase transition,

That is because a heart or kidney lasts only a matters of hours packed in ice,

The liquid layer on the surface provides a barrier to everything from ice to crude oil and blood.

Eventually they settled on a thermal energy storage system that uses a phase-change material to store energy in the form of ice.
