Electron flux is a key determinant of uranium isotope fractionation during bacterial reduction
Communications Earth & Environment, 2023 Uranium isotopic signatures in the rock record are utilized as a proxy for past redox conditions on Earth. However, these signatures display significant variability that complicates the interpretation of specific redox conditions. Using the model uranium-

Modelling U(VI) Reduction by Pseudomonas stutzeri
Chemical Engineering Transactions, 2012 Pseudomonas stutzeri, a facultative anaerobe sourced from soil in a uranium mine in Limpopo, South Africa, reduced uranium-6 (U(VI)) to uranium-4 (U(IV)) in batches under a relatively high initial U(VI) concentration ranging from 30 to 400 mg/L (pH 5 to ...

Chemistry – A European Journal, EarlyView.A semi‐empirical Stokes‐Einstein‐based model for describing the diffusion of organic, organometallic and coordination compounds is developed for the interpretation of diffusion constants obtained by diffusion‐ordered NMR spectroscopy (DOSY). This model uses the molecular volume as a descriptor and shows a high accuracy, enabling application to ...

Persilylated and Related Silyl Anion‐Induced Synthesis of Group 3–10 Metal–Silyl Complexes
Chemistry – A European Journal, EarlyView.Persilylated and related silyl anions serve as powerful tools for constructing metal–silyl complexes across group 3–10 elements. Their strong σ‐donating ability and steric bulk stabilize low‐coordinate, reactive species and enable unique bonding motifs.
