It might help, though - if you suddenly stop applying the magnetic fields, then it might freeze more abruptly than if you simply lower the temperature. That could reduce the extent of crystallization and thus damage.
Precisely. Normally, vitreous H2O (glass phase of ice) is produced through 1 of 2 methods:
Pouring liquid H2O on a highly conductive heatsink which is cooled to liquid nitrogen temperatures (Ie, a block or sheet of copper in contact with LN)
Taking a block of ice and compressing it at low temperatures.
The first method only works for thin sheets of ice, or creates a thin vitreous layer on the outside of a larger water-filled object. The second method allows one of the normal phases of ice to form, and then converts it to vitreous ice.
However, if we cou...
This is great, by using small interlocking magnetic fields, you can keep the water in a higher vibrational state, allowing a "super-cooling" without getting crystallization and cell rupture
Subzero 12-hour Nonfreezing Cryopreservation of Porcine Heart in a Variable Magnetic Field
"invented a special refrigerator, termed as the Cells Alive System (CAS; ABI Co. Ltd., Chiba, Japan). Through the application of a combination of multiple weak energy sources, this refrigerator generates a special variable magnetic field that causes water molecules to oscillate, thus inhibiting crystallization during ice formation18 (Figure 1). Because the entire material is frozen without the movement of water molecules, cells can be maintained intact and free of membranous damage. This refrigerator has the ability to achieve a nonfreezing state even below the solidifying point."
