Description générale

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.

Application

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).

In this work, solar disinfection (SODIS) was enhanced by moderate addition of Fe and sodium peroxydisulfate (PDS), under solar light. A systematic assessment of the activating factors was performed, firstly isolated, then in pairs and concluded in the combined Fe/heat/solar

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

Magnetotactic bacteria align along the Earth's magnetic field using an organelle called the magnetosome, a biomineralized magnetite (Fe(II)Fe(III)2O4) or greigite (Fe(II)Fe(III)2S4) crystal embedded in a lipid vesicle. Although the need for both iron(II) and iron(III) is clear, little is known
