Iron (Fe) is the fourth most abundant element in the earth's crust and plays important roles in
both biological and chemical processes. The redox reactivity of various Fe (II) forms has …

Microbial dissimilatory sulfate reduction to sulfide is a predominant terminal pathway of
organic matter mineralization in the anoxic seabed. Chemical or microbial oxidation of the …

Iron-based materials used in water treatment and groundwater remediation especially
micro-and nanosized zerovalent iron (nZVI) can be more effective when modified with …

The addition of iron is a convenient way for removing phosphorus from wastewater, but this
is often considered to limit phosphorus recovery. Struvite precipitation is currently used to …

Almost the entire seafloor is covered with sediments that can be more than 10 000 m thick
and represent a vast microbial ecosystem that is a major component of Earth's element and …

Reduction–oxidation (redox) reactions occur during burial because sediments contain
reactive mixtures of oxidised and reduced components. Diagenetic chemical reactions …

In environmental magnetism, rock and mineral magnetic techniques are used to investigate
the formation, transportation, deposition, and postdepositional alterations of magnetic …

The oxygen content of the Earth's surface environment is thought to have increased in two
broad steps: the Great Oxygenation Event (GOE) around the Archean–Proterozoic boundary …

As consequence of the dual demands for pollution control and carbon (C) fixation in soils, Fe
(II)-catalyzed mineral transformation may be a promising method to simultaneously …

Redox-driven biogeochemical element cycles play a central role in converting organic
matter in aquatic ecosystems. They also perform key functions such as removing nitrate …
