Secondary ion mass spectrometry (SIMS) is a technique for chemical analysis and imaging
of solid materials, with applications in many areas of science and technology. It involves …

Iron is the most abundant redox‐active metal in the Earth's crust. The one electron transfer
between the two most common redox states, Fe (II) and Fe (III), plays a role in a huge range …

Microbially mediated nitrate reduction coupled with Fe (II) oxidation (NRFO) plays an
important role in the Fe/N interactions in pH-neutral anoxic environments. However, the …

Microbially driven nitrate-dependent iron (Fe) oxidation (NDFO) in subsurface environments
has been intensively studied. However, the extent to which Fe (II) oxidation is biologically …

Pyrite, or iron disulfide, is the most common sulfide mineral on the Earth's surface and is
widespread through the geological record. Because sulfides are mainly produced by sulfate …

Biologically induced and controlled mineralization of metals promotes the development of
protective structures to shield cells from thermal, chemical, and ultraviolet stresses. Metal …

Abstract Hexavalent chromium (Cr (VI)) could be sequestrated by soils via microbial
reduction to Cr (III) and association with minerals, however, quantitative understanding of …

Microbial nitrate reduction can drive Fe (II) oxidation in anoxic environments, affecting the
nitrous oxide emission and ammonium availability. The nitrate-reducing Fe (II) oxidation …

Résumé Prokaryotes have been sha** the surface of the Earth and impacting
geochemical cycles for the past four billion years. Biomineralization, the capacity to form …

Nitrification and denitrification play a vital role in the conversion of fixed nitrogenous
compounds to nitrogen gas. In anoxic environments, nitrogen loss is attributed to autotropic …
