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:

Prevention of radioactive pollution: A comparative simulation study on the reduction of several important radionuclides by pyrite and magnetite
TL;DR: In this article , the reducing reaction between pyrite, magnetite, and redox-sensitive radionuclides (U, Se, Tc, and Np) in the Gansu proposed-treatment plant area was under simulation by PHREEQC.
Dissertation
Speciation and reduction of U(VI) in acidic chloride brines under hydrothermal conditions: From transport to deposition of uranium in unconformity-related deposits
TL;DR: In this article, the authors performed experimental studies of U6+ speciation and its reduction to U4+ and subsequently precipitation to UO2 under hydrothermal condition, showing the coexistence of several uranyl chloride complexes.
Palaeoceanography of the mid-latitude North East Pacific : during the late Pleistocene
TL;DR: In this article, past climatic and oceanographic changes in the California Current region off western North America were investigated with the overall goal of contributing to a better understanding of natural ocean variability in the Pacific Ocean on glacial-interglacial and millennial-time scales.

Neutrophilic Bacteria in Iron Mineral Transformation and Their Applications
TL;DR: The natural biogenic transformations by the neutrophilic bacteria with suitable eco-engineering can be adopted in the field of bioremediation to combat the increasing environmental pollution as discussed by the authors, however, according to the pH of the environmental niches in the oxic-anoxic soils and freshwater sediments, neutrophILI and IRB play active roles in mineral transformations.

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.
