Journal ArticleDOI
Ligand K-edge x-ray absorption spectroscopy: Covalency of ligand-metal bonds
TL;DR: The ligand K-edge probes the ligand 1s → valence np transitions as discussed by the authors and quantifies the amount of ligand character in the metal d orbitals, hence the covalency of the ligands-metal bond.
Journal ArticleDOI
Molecular electrocatalysts for the oxygen reduction reaction
TL;DR: In this paper, a review of recent developments in homogeneous and heterogeneous molecular ORR catalysis, placing emphasis on reaction mechanisms and the factors governing rates and selectivities, is presented.
Journal ArticleDOI
Solvent tuning of electrochemical potentials in the active sites of HiPIP versus ferredoxin
Abhishek Dey,Francis E. Jenney,Michael W. W. Adams,Elena Babini,Yasuhiro Takahashi,Keiichi Fukuyama,Keith O. Hodgson,Britt Hedman,Edward I. Solomon +8 more
TL;DR: Studies on model compounds and accompanying density functional theory calculations support a correlation of Fe-S covalency with ease of oxidation and therefore suggest that hydration accounts for most of the difference between Fd and HiPIP reduction potentials.
Journal ArticleDOI
Cobalt Corrole Catalyst for Efficient Hydrogen Evolution Reaction from H2O under Ambient Conditions: Reactivity, Spectroscopy, and Density Functional Theory Calculations
Biswajit Mondal,Kushal Sengupta,Atanu Rana,Atif Mahammed,Mark Botoshansky,Somdatta Ghosh Dey,Zeev Gross,Abhishek Dey +7 more
TL;DR: Density functional theory (DFT) calculations indicate that the electron density on a putative hydride species is delocalized off from the H atom into the macrocycle, which makes the protonation of a [Co(III)-H](-) species the rate determining step for the HER consistent with the experimental data.
Journal ArticleDOI
Using a functional enzyme model to understand the chemistry behind hydrogen sulfide induced hibernation
TL;DR: Experiments imply that H2S might also serve as a source of electrons during periods of hibernation when food supplies are low, and also reduce CcO's biological reductant, cytochrome c, which normally derives its reducing equivalents from food metabolism.
