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", A. G. Stack, S. R. Higgins, Carrick Eggleston

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 crystal face of corundum using optical second harmonic generation (SHG) at a pH (∼5) much lower than the accepted value (in the 8–9 range) of the pristine p.z.c. of alumina powders. Dr. Kosmulski’s main claim is that our anomalous observation is the result of surface contamination.

Carrick M Eggleston
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 is important for understanding metal redox cycling in soils and sediments, for utilizing DMRB in bioremedation, and for developing technologies such as microbial fuel cells. Here we hypothesize that the outer membrane cytochromes OmcA and MtrC from Shewanella oneidensis MR-1 are the only terminal reductases capable of direct electron transfer to a hematite working electrode. Cyclic voltammetry (CV) was used to study electron transfer between hematite electrodes and protein films, S. oneidensis MR-1 …

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 alpha-Fe2O3 (001) surfaces is not fully understood, and questions have arisen recently concerning different terminations of (001) terraces; a so-called Fe-termination is expected, but under some conditions an O-termination may also be possible. Ultra-high vacuum (UHV) scanning tunneling microscope (STM) studies report evidence for an O-termination in coexistence with an Fe-termination, but other studies find no evidence for an O-termination. Molecular mechanics studies suggest that an O-termination should be possible in an aqueous environment. …

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. One of the pathways that could trigger electron transfer between proteins and minerals is redox-linked conformation change. We present electrochemical evidence that mitochondrial cytochrorne c (Mee) undergoes significant conformation change upon interaction with hematite and indiurn-tin oxide (ITO) surfaces. The apparent adsorption-induced conformation change causes the protein to become more reducing, which makes it able to transfer electrons to the hematite conduction band. Although Mcc is not a protein thought …

Adatom Fe(Iii) On The Hematite Surface: Observation Of A Key Reactive Surface Species, Carrick Eggleston, A. G. Stack, K. M. Rosso, A. M. Bice

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 growth theories, and many other studies of mineral surface reactivity appeal to ill-defined "active sites." Despite their theoretical importance, there has been little direct experimental or analytical investigation of the structure and properties of such species. Here, we use ex-situ and in-situ scanning tunneling microcopy (STM) combined with calculated images based on a resonant tunneling model to show that observed nonperiodic protrusions and depressions …
