Strong correlations in actinide redox reactions.
Reduction-oxidation (redox) reactions of the redox couples An(VI)/An(V), An(V)/An(IV), and An(IV)/An(III), where An is an element in the family of early actinides (U, Np, and Pu), as well as Am(VI)/Am(V) and Am(V)/Am(III), are modeled by combining density functional theory with a generalized Anderson impurity model that accounts for the strong correlations between the 5f electrons. Diagonalizat...
متن کاملREACTION KINETICS OF RARE EARTH AND ACTINIDE MATERIALS by
This dissertation presents the effects of atmosphere, time, and energy input (thermal and mechanical) on the kinetics of gas-solid and solid-solid reactions in systems of dysprosium, uranium, oxygen, and nitrogen. Accordingly, Chapter Two presents a novel synthesis technique used to form DyN via a gas-solid reaction between dysprosium and nitrogen. DyN was rapidly formed through a mechanochemic...
متن کاملToward Understanding the Thermodynamics of TALSPEAK Process -- Medium Effects on Actinide Complexation
The ingenious combination of lactate and diethylenetriamine-N,N,N’,N”,N”pentaacetic acid (DTPA) as an aqueous actinide-complexing medium forms the basis of the successful separation of americium and curium from lanthanides known as the TALSPEAK process. While numerous reports in the prior literature have focused on the optimization of this solvent extraction system, considerably less attention ...
متن کاملKinetics of Ballistically-Controlled Reactions
We investigate the kinetics of generic single-species reaction processes when the reactants move ballistically, namely ballistic annihilation, A + A 0, and a ballistic aggregation process which mimics traffic flow on a single-lane roadway. For ballistic annihilation, dimensional analysis shows that the concentration and root means square velocity decay as c P and u N r-6, respectively, with a +...
متن کاملSurface complexation reactions of inorganic anions on hydrotalcite-like compounds.
Complexation reactions of environmentally important inorganic anions such as nitrate, chloride, sulfate, arsenate, and phosphate on the surface of hydrotalcite-like compounds (HT) were investigated to understand the role of HT in the immobilization of hazardous anions in an alkaline environment. The effects of surface complexation reactions on the solid state properties of HT were also evaluate...
