Descripción general

Iron(II,III) oxide is an earth-abundant magneticoxide that has a high specific surface area, and good dispersion. The presenceof Fe3+ and Fe2+ with equal numbers in the Fe3O4structure provides higher light absorption and as a result superiorelectrocatalytic activities and high performance in solar cells compared toother iron oxides.

Aplicación

Iron(II,III) oxide can be used as:
  • A starting material to synthesize Ca2Fe2O5 (srebrodolskite) microspheres via a single-stage flame spheroidisation (FS) process.
  • A catalyst for reverse water gas shift reactions(RWGS).

Mechanosensitivity is a well-known feature of astrocytes, however, its underlying mechanisms and functional significance remain unclear. There is evidence that astrocytes are acutely sensitive to decreases in cerebral perfusion pressure and may function as intracranial baroreceptors, tuned to monitor brain
