TL;DR: In this paper, pump-probe spectroscopy was used to study the dynamics of electrons introduced into iron(III) (oxyhydr)oxide nanoparticles via ultrafast interfacial electron transfer.
Journal ArticleDOI
Origin of the differences in redox reactivity of metal (oxyhydr)oxides revealed by time-resolved spectroscopy.
Journal ArticleDOI
Surface potentials of (001), (012), (113) hematite (α-Fe2O3) crystal faces in aqueous solution.
TL;DR: A new surface complexation model based on fitting the entire data set that depends primarily only on the proton affinities of two site types and the two associated electrical double layer capacitances is introduced, showing that magnitudes of surface potential biases at the pH extremes are on the order of 100 mV.
Journal ArticleDOI
Molecular Dynamics Study of Fe(II) Adsorption, Electron Exchange, and Mobility at Goethite (α-FeOOH) Surfaces
TL;DR: In this article, the adsorption free energy profiles for the aqueous Fe(II) ion approaching key low-index crystal faces of goethite at neutral surface charge conditions are presented.
Journal ArticleDOI
Thermodynamics of Electron Flow in the Bacterial Deca-heme Cytochrome MtrF
TL;DR: Large-scale molecular dynamics simulations are employed to compute the redox potentials of the 10 hemes of MtrF in aqueous solution, finding that as a whole they fall within a range of ~0.3 V, in agreement with experiment.
