In soil environments, the sequestration and transformation of organic carbon are closely
associated with soil minerals. Birnessite (MnO2) is known to strongly interact with soil …

The increasing intensity of human activities has led to a critical environmental challenge:
widespread metal pollution. Manganese (Mn) oxides have emerged as potentially natural …

Rechargeable Zn-ion batteries working with manganese oxide cathodes and mild aqueous
electrolytes suffer from notorious cathode dissolution during galvanostatic cycling. Herein …

The pursuit of a high surface area while maintaining high catalytic performance remains a
challenge due to a trade-off relationship between these two features in some cases. In this …

Birnessite minerals help control the fate of Zn in surface environments and readily
fractionate Zn isotopes through adsorption reactions, yet little is known about the role played …

MnO2 nanoparticles, similar to those found in soils and sediments, have been characterized
via their UV–visible and Raman spectra, combined with dynamic light scattering and …

Arsenic (As) contamination of drinking water is a threat to global health. Manganese
(III/IV)(Mn) oxides control As in groundwater by oxidizing more mobile AsIII to less mobile …

Birnessite, a layered manganese (Mn) oxide, possesses extraordinary metal adsorption and
oxidation activity, and thus imposes impacts on many biogeochemical processes. The …

Cadmium (Cd) geochemical behavior is strongly influenced by its adsorption onto natural
phyllomanganates, which contain both layer edge sites and vacancies; however, Cd isotope …

Adsorptive fractionation and oxidation of dissolved organic matter (DOM) on manganese
(Mn) oxide surfaces alter the molecular composition and stability of DOM, but the impact of …
