Spectroscopic characterization of the iron-oxo intermediate in cytochrome P450

From analogy to chloroperoxidase from Caldariomyces fumago, it is believed that the electronic structure of the intermediate iron-oxo species in the catalytic cycle of cytochrome P450 corresponds to an iron(IV) porphyrin-?-cation radical (compound I)...

A kinetic study of UO2 dissolution and H2O2 stability in the presence of groundwater ions

Current reactors spent nuclear UO2 fuel, that will probably enter geologic formations for disposal, is assumed to get into contact with groundwater of a repository earliest after several thousands of years...
