This is *not CAS,* but seems of interest - Igor Artyuhov.

Crack avoidance during cryopreservation attempts*K. Kletetschka, G.

This investigation tests whether fracture formation in cryo-preserved ice
containing bodies could be affected by alternating magnetic field. The
experiment was done on ion containing water inside a plastic container.
Magnetism was used to stabilize/balance the pressure exerted during the
freezing process. First we tested whether steady application of strong
magnetic field has any positive effect on fracture formation, namely,
whether a continuous magnetic field exposure can induce any specific
fracture pattern. Using the direct current in the electromagnet the effect
on fractures was negligible. However, when freezing the water by liquid
nitrogen exposed to the alternating current generated magnetic field, we did
not observed any fracture formation. When alternating magnetic field was
absent, the water frozen by liquid nitrogen contained multiple radial
fractures.
Our hypothesis is that rapidly changing magnetic field generates eddy
currents inside the water and this shifts the phase transition between the
liquid water and solid forming ice, allowing stress relieve within the new
ice.
Our observation suggests to use alternating magnetic field chambers during
the cryopreservation procedure because fractures are one of the critical
concerns of cryonics.
