Persulfate Activation on Crystallographic Manganese Oxides: Mechanism of Singlet Oxygen Evolution for Nonradical Selective Degradation of Aqueous Contaminants.

open access: yesEnvironmental Science and Technology, 2018
Minerals and transitional metal oxides of earth-abundant elements are desirable catalysts for in situ chemical oxidation in environmental remediation. However, catalytic activation of peroxydisulfate (PDS) by manganese oxides was barely investigated.

Design Principles for Enhancing Photoluminescence Quantum Yield in Hybrid Manganese Bromides.

open access: yesJournal of the American Chemical Society, 2020
Hybrid manganese halides have attracted widespread attention because of their highly emissive optical properties. To understand the underlying structural factors that dictate the photoluminescence quantum yield (PLQY) of these materials, we report five ...

The Essential Element Manganese, Oxidative Stress, and Metabolic Diseases: Links and Interactions

open access: yesOxidative Medicine and Cellular Longevity, 2018
Manganese (Mn) is an essential element that is involved in the synthesis and activation of many enzymes and in the regulation of the metabolism of glucose and lipids in humans. In addition, Mn is one of the required components for Mn superoxide dismutase

Bacterial chemolithoautotrophy via manganese oxidation

open access: yesNature, 2020
Manganese is one of the most abundant elements on Earth. The oxidation of manganese has long been theorized1—yet has not been demonstrated2–4—to fuel the growth of chemolithoautotrophic microorganisms.
