Life on earth is almost entirely solar-powered. We can get some idea of the enormous
quantity of energy received from the sun by noting that during daylight hours, the sun …

Oxygenic photosynthesis, the principal converter of sunlight into chemical energy on earth,
is catalyzed by four multi-subunit membrane-protein complexes: photosystem I (PSI) …

Manganese (Mn) is an essential element for plants which intervenes mainly in
photosynthesis. In this study we establish that manganese nanoparticles (MnNP) work as a …

Among molecular water oxidation catalysts (WOCs), those featuring a reactive set of four
multi-redox transition metals can leverage an extraordinary interplay of electronic and …

Iron is involved in many photosynthetic, respiratory and nitrogen assimilation reactions of
plants as Fe bound tightly to polypeptides catalysing redox reactions. Manganese is …

In oxygenic photosynthesis, electron transport for the generation of reductant, in the form of
reduced ferredoxin and NADPH, and for the formation of ATP takes place in the thylakoid …

Since 1975, when the first short-lived (nanoand picosecond) intermediates of
photosynthesis were detected, much has been learned of the photochemical domain of …

Manganese oxidation, catalyzed by chlorophyll photochemistry in photosystem II, is the key
step in the pathway of redox reactions leading formation of O2 from H2O. A unique feature of …
