WebPhotosynthetic water oxidation is catalyzed by a Mn 4 O 5 Ca cluster with an unprecedented arrangement of metal ions in which a single manganese center is bonded to a distorted Mn 3 O 4 Ca cubane-like structure. Several mechanistic proposals describe the unique manganese center as a site for water binding and subsequent formation of a … WebDive into the research topics of 'Enhancement of soot oxidation activity of manganese oxide (Mn 2 O 3) through doping by the formation of Mn 1.9 M 0.1 O 3–δ (M = Co, Cu, and Ni)'. Together they form a unique fingerprint.
