  • Magnetite-based heterogeneous ice-crystal nucleation
    Patent number: 10285420
    Abstract: Ice nucleation and supercooling are controlled by the presence of magnetite particles. Magnetite decreases supercooling and promotes ice nucleation. Therefore, freezing of liquid solutions occurs at higher temperature compared to supercooled solutions. Applying a magnetic field allows control of supercooling and ice nucleation.
    Type: Grant
    Filed: January 13, 2017
    Date of Patent: May 14, 2019
    Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGY
    Inventors: Atsuko Kobayashi, Joseph L. Kirschvink

  • ENHANCEMENT OF ELECTROMAGNETIC FREEZING BY STABILIZATION AND OSCILLATION OF BIOGENIC MAGNETITE PARTICLES
    Publication number: 20160227763
    Abstract: Novel methods and systems for electromagnetic freezing are disclosed. An oscillating magnetic field can be applied in conjunction with a static magnetic field in order to align magnetic particles inside biological tissues. Such chains may be naturally present or artificially introduced. Needle-shaped electrodes may be used to produce ions and disturb the air layers insulating the tissues to be frozen.
