TLDR
In this article, the authors investigated the kinetic effect of specific adsorption interactions on the chemical reduction of uranyl (UVIO22+) by ferrous iron, and derived a rate law for surface-catalyzed U(VI) reduction by Fe(II), d[U(VI)] dt =−k[≡ Fe III OFe II OH 0 ][U( VI)] ads where the bimolecular rate constant k has a value of 399 ± 25 M−1 min−1 at 25°C.About:

Microbial Fe(III) Reduction: Ecological and Physiological Considerations
TL;DR: It is clear that cell attachment to mineral surfaces is common in all FeRB studied and is probably essential to Fe(III) reduction, and the abundance of c-type cytochromes in almost every organism studied.

Microbially Mediated Immobilization of Contaminants Through In Situ Biostimulation
TL;DR: To assess the feasibility of in situ immobilization of uranium in subsurface environments and to understand the cycling of uranium, it is necessary to discern the chemical and/or biological conditions dictating which terminal electron acceptor(s) will be utilized.
Dissertation
Electrochemical Investigations of Redox Reactions of Uranyl(VI) on Magnetite and Computational Modeling of the UO2-HfO2 Solid Solution.
TL;DR: In this article, an in situ approach for the investigation of the intermediate reaction of U(V)O2+ on the surfaces of magnetite was provided. But, the results were limited to the case of UO2 + and UO 2 + on the surface of powder and bulk magnetite.

Uranium solution-mineral equilibria at low temperatures with applications to sedimentary ore deposits
TL;DR: The Gibbs free energies, enthalpies and entropies of 42 dissolved uranium species and 30 uranium-bearing solid phases have been critically evaluated from the literature and estimated when necessary for 25°C.
