Metal reduction kinetics inShewanella [PDF]
Bioinformatics, 2007 AbstractMotivation: Metal reduction kinetics have been studied in cultures of dissimilatory metal reducing bacteria which include the Shewanella oneidensis strain MR-1. Estimation of system parameters from time-series data faces obstructions in the implementation depending on the choice of the mathematical model that captures the observed dynamics. The

Reduction kinetics and electrochemistry of tetracarboxylate nitroxides. [PDF]
Free Radic Res, 2018 Tetracarboxylate pyrroline nitroxides undergo very fast reduction with ascorbate/glutathione (GSH), with second-order rate constants that are five orders of magnitude greater than those for gem-diethyl pyrroline nitroxides. For tetracarboxylate nitroxides, the electrochemical reduction potentials, measured by square wave voltammetry, are much less ...

Kinetic Equation for Soliton Gas: Integrable Reductions [PDF]
Journal of Nonlinear Science, 2022 AbstractMacroscopic dynamics of soliton gases can be analytically described by the thermodynamic limit of the Whitham equations, yielding an integro-differential kinetic equation for the density of states. Under a delta-functional ansatz, the kinetic equation for soliton gas reduces to a non-diagonalisable system of hydrodynamic type whose matrix ...

Reduction of Ferric Iron in Hydrometallurgical Solutions Using Zero-Valent Iron
Materials Proceedings, 2022 Most hydrometallurgical solutions usually contain high levels of ferric iron, which is often regarded as a major and problematic impurity. Precipitation of Fe(III) by raising the solution pH results in a voluminous amorphous residue that is particularly ...

Hyperbolic Model Reduction for Kinetic Equations
, 2022 AbstractWe make a brief historical review of the moment model reduction for the kinetic equations, particularly Grad’s moment method for Boltzmann equation. We focus on the hyperbolicity of the reduced model, which is essential for the existence of its classical solution as a Cauchy problem. The theory of the framework we developed in the past years is
