Ab initio and steady-state models for uranium isotope fractionation in multi-step biotic and abiotic reduction

Rizlan Bernier-Latmani

Hexavalent uranium (U(VI)) is reduced to tetravalent uranium (U(IV)) by microorganisms (e.g., Geobacter or Shewanella spp.) as well as by abiotic reductants such as sulfide or Fe(II) species. During reduction, the heavy isotope (238U) is typically enriched ...

Dissipation-Driven Selection under Finite Diffusion: Hints from Equilibrium and Separation of Time Scales

Paolo De Los Rios, Shiling Liang, Daniel Maria Busiello

When exposed to a thermal gradient, reaction networks can convert thermal energy into the chemical selection of states that would be unfavourable at equilibrium. The kinetics of reaction paths, and thus how fast they dissipate available energy, might be do ...

Improved Modeling of Sediment Oxygen Kinetics and Fluxes in Lakes and Reservoirs

Alfred Johny Wüest

To understand water quality degradation during hypoxia, we need to understand sediment oxygen ﬂuxes, the main oxygen sink in shallow hypolimnia. Kinetic models, which integrate diﬀusion and consumption of dissolved oxygen (DO) in sediments, usually assume ...
