Redox-Linked Conformation Change and Electron Transfer Between Monoheme C-Type Cytochromes and Oxides
Contributor:Khare, N.; Lovelace, D. M.; Eggleston, Carrick; Swenson, M.; Magnuson, T. S.
Electron transfer between redox active proteins and mineral oxides is important in a variety of natural as well as technological processes, including electron transfer from dissimilatory metal-reducing bacteria to minerals. ...
Response to Comment on "Point of Zero Charge of a Corundum-Water Interface Probed with Optical Second Harmonic Generation (SHG) and Atomic Force Microscopy (AFM) : New Approaches to Oxide Surface Charge"
Contributor:Stack, A. G.; Higgins, S. R.; Eggleston, Carrick
The purpose of this response is to address several misrepresentations of Stack et al. (2001) and its intent in the preceding Comment. At issue, primarily, is our observed point of zero salt effect (p.z.s.e.) of a single ...
Electrochemical Interaction of Shewanella Oneidensis Mr-1 and Its Outer Membrane Cytochromes Omca and MTRC with Hematite Electrodes
Contributor:Meitl, L. A.; Eggleston, Carrick; Colberg, P. J. S.; Khare, N.; Reardon, C. L.; Shi, L.
Bacterial metal reduction is an important biogeochemical process in anaerobic environments. An understanding of electron transfer pathways from dissimilatory metal-reducing bacteria (DMRB) to solid phase metal (hydr)oxides ...
Adatom Fe(III) on the Hematite Surface : Observation of a Key Reactive Surface Species
Contributor:Eggleston, Carrick; Stack, A. G.; Rosso, K. M.; Bice, A. M.
The reactivity of a mineral surface is determined by the variety and population of different types of surface sites (e.g., step, kink, adatom, and defect sites). The concept of "adsorbed nutrient" has been built into crystal ...
Structure of Hematite (α-Fe2O3) (001) Surfaces in Aqueous Media : Scanning Tunneling Microscopy and Resonant Tunneling Calculations of Coexisting O and Fe Terminations, The
Contributor:Eggleston, Carrick; Stack, A. G.; Rosso, K. M.; Higgins, S. R.; Bice, A. M.; Boese, S. W.; Pribyl, R. D.; Nichols, J. J.
The iron oxide-water interface is of interest not only in geochemical and environmental processes, but also in fields ranging from corrosion to photocatalysis. The structure of α-Fe2O3 (001) surfaces is not fully understood, ...
