Manganese (Mn) is a biologically important and redox-active metal that may exert a poorly
recognized control on carbon (C) cycling in terrestrial ecosystems. Manganese influences …

Birnessite is ubiquitous in the natural environment where heavy metals are retained and
easily transformed. The surface properties and structure of birnessite change with the …

Raman spectra were collected for an extensive set of well-characterized layer-structure Mn
oxide mineral species (phyllomanganates) employing a range of data collection conditions …

The reaction of manganese oxides with Cr (III)-bearing solids in soils and sediments can
lead to the natural production of Cr (VI) in groundwater. Building on previous knowledge of …

The structure and Mn (III) concentration of birnessite dictate its reactivity and can be
changed by birnessite partial reduction, but effects of pH and reductant/birnessite ratios on …

Birnessite (δ-MnO2) is a layered manganese oxide widely present in the environment and
actively participates in the transformation of natural organic matter (NOM) in biogeochemical …

Dissolved Mn (III) species have recently been recognized as a significant form of Mn in
redox transition zones, but their speciation, stability, and reactivity are poorly understood …

Jarosite and birnessite secondary minerals play a pivotal role in the mobility, transport and
fate of trace elements in the environment, although geochemical interactions of these …

Metal (oxyhydr) oxides are key factors for the transformation and stabilization of organic
carbon (OC) in soil. While sorptive interactions between Al and Fe (oxyhydr) oxides and …

Manganese (Mn) oxides have been prevalent on Earth since before the Great Oxidation
Event and the Mn cycle is one of the most important biogeochemical processes on the …
