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 …

Cadmium (Cd) contamination of soils is a global problem, particularly in paddy soils. Fe
oxides, as a key fraction of paddy soils, can significantly affect the environmental behavior of …

Reactive oxygen species (ROS) play key roles in driving biogeochemical processes. Recent
studies have revealed nonphotochemical electron transfer from redox-active substances …

In this article, we provide a critical review on the occurrence, formation, structure and stability
of schwertmannite–an enigmatic Fe (III) oxyhydroxy-sulfate mineral that is of widespread …

Microbially mediated iron redox processes are of great significance in the biogeochemical
cycles of elements, which are often coupled with soil organic matter (SOM) in the …

Natural occurring ferrihydrite (Fh) nanoparticles have varying degrees of crystallinity, but
how Fh crystallinity affects its transformation behavior remains elusive. Here, we …

Cr (VI) detoxification and organic matter (OM) stabilization are usually influenced by the
biological transformation of iron (Fe) minerals; however, the underlying mechanisms of …

In redox-affected soil environments, electron transfer between aqueous Fe (II) and solid-
phase Fe (III) catalyzes mineral transformation and recrystallization processes. While these …

Interactions between aqueous ferrous iron (Fe (II)) and secondary Fe oxyhydroxides
catalyze mineral recrystallization and/or transformation processes in anoxic soils and …

Cadmium (Cd) isotopes have great potential for understanding Cd geochemical cycling in
soil and aquatic systems. Iron (oxyhydr) oxides can sequester Cd via adsorption and …
