Polynuclear Cobalt Complexes as Models of a Cobalt Water Oxidation Catalyst
(2015-08-18)
The electrochemical oxidation of Co2+ ions in the presence of a buffering species such as phosphate (Pi), methyl phosphonate (MePi), and borate (Bi) leads to the formation of amorphous cobalt oxide thin films that are ...
The Development and Analysis of Model Systems to Probe Proton-Coupled Electron Transfer in Ribonucleotide Reductase Ia of E. Coli
(2016-05-17)
Proton-coupled electron transfer (PCET) combines proton transfer with electron transfer to bypass high-energy intermediates. The ribonucleotide reductase (RNR) family of enzymes catalyzes the conversion of ribonucleotides ...
Mechanistic Studies of First-Row Metal-Mediated and -Catalyzed Reactions
(2018-04-10)
First-row transition metals find growing applications in organic transformations due to their abundance and low cost. In addition, the difference in redox states of first-row metals to those of second or third row metals ...
Patterning Metal Oxides Using Electrochemical Methods and Exploring the Dynamics of Water-Splitting Catalysts
