The effect of natural organic matter on the formation and solubility of M(OH)4 solid phases
(2014)In this study the formation of M(OH)4 solid phases (e.g. Th(IV), Ce(IV) and Zr(IV)) has been investigated as a function of the natural organic matter (NOM) concentration in 0.1 M NaClO4, in the pH range between 2 and 5, ...

The effects of Fe on the oxygen storage and release properties of model Pd-Rh/CeO2-Al2O3 three-way catalyst
(2006)This work attempts to gain fundamental information about the role of Fe in the chemical deactivation of a three-way catalyst (TWC), with Fe originating from materials used in the construction of automotive engines and ...

The effects of P-poisoning of CexZr1-xO2 on the transient oxygen storage and release kinetics
(2013)The present work reports on the investigation of the effects of chemical poisoning of CexZr1-xO2 solids by phosphorous (P) on the kinetics of oxygen storage and release (OSR) of the thus derived P-contaminated solids, as ...

The effects of the use of weak organic acids on the improvement of oxygen storage and release properties of aged commercial three-way catalysts
(2005)The efficiency of weak organic acid solutions for improving the oxygen storage and release properties of aged commercial three-way catalysts (TWC) has been investigated. For the first time, three candidate leaching solutions, ...

Preparation and characterization of a cerium(IV)-incorporated manganese oxide OMS-2. Effect of cerium(IV) template on octahedral molecular sieves of manganese oxide and characterization of manganese oxide molecular sieves with cerium(IV) as dopant
(2008)The manganese oxide material K-OMS-2 was synthesized both via a redox reaction between potassium permanganate and manganese nitrate in an acidic medium (nitric acid) under reflux conditions and by the sol-gel reaction ...

Protein dynamics and electron transfer: Electronic decoherence and non-Condon effects
(2005)We compute the autocorrelation function of the donor-acceptor tunneling matrix element 〈TDA(t)TDA(0)〉 for six Ru-azurin derivatives. Comparison of this decay time to the decay time of the time-dependent Franck-Condon factor ...

Seasonal variation, chemical behavior and kinetics of uranium in an unconfined groundwater system
(2014)The seasonal changes in the concentration of uranium in an unconfined groundwater system in Cyprus have been investigated and compared to corresponding changes of boron and salinity, to better understand the chemical ...

Two-Electron Transfer Pathways
(2015)The frontiers of electron-transfer chemistry demand that we develop theoretical frameworks to describe the delivery of multiple electrons, atoms, and ions in molecular systems. When electrons move over long distances through ...
