Effect of Ni2+, Zn2+, and Co2+ on green rust transformation to magnetite
Geochemical Transactions, 2022 In this study, we investigated Ni2+, Zn2+, and Co2+ mineralogical incorporation and its effect on green rust transformation to magnetite. Mineral transformation experiments were conducted by heating green rust suspensions at 85 °C in the presence of Ni2+,

Electrical conductivity of magnetite‐bearing serpentinite during shear deformation
Geophysical Research Letters, 2012 Electrical conductivity of serpentinite with various amounts of magnetite was measured during shear deformation at high pressure and temperatures (P = 1.0 GPa, T = 750 K) corresponding to mantle wedge conditions to evaluate the contribution of aligned ...

Magnetite and magnetotaxis in microorganisms
Bioelectromagnetics, 1988 AbstractMagnetotactic bacteria from freshwater and marine sediments orient and navigate along geomagnetic field lines. Their magnetotactic response is based on intracellular, single magnetic domains of ferrimagnetic magnetite, which impart a permanent magnetic dipole moment to the cell.

Necessity of electrically conductive pili for methanogenesis with magnetite stimulation [PDF]
PeerJ, 2018 Background Magnetite-mediated direct interspecies electron transfer (DIET) between Geobacter and Methanosarcina species is increasingly being invoked to explain magnetite stimulation of methane production in anaerobic soils and sediments.

Interactions between magnetite and humic substances: redox reactions and dissolution processes
Geochemical Transactions, 2017 Humic substances (HS) are redox-active compounds that are ubiquitous in the environment and can serve as electron shuttles during microbial Fe(III) reduction thus reducing a variety of Fe(III) minerals.
