The reactivity of aqueous sulfate toward magnetite was studied between 50 and 275 °C as a function of pH and the redox conditions. Under oxidizing conditions, we did not observe redox reactions and the sorption of aqueous sulfate is promoted under a

We are developing the use of noble gases as tools to survey the integrity of CO 2 geological storages. The advantage of using noble gases stems from their chemical inactivity which does not delay them when they migrate in leaking pathways. Using the

Periodic DFT calculations using plane waves basis sets with the GGA formalism were performed in order to study the behavior of the UO 2 2 + uranyl ion at the water–Ni(1 1 1) interface. First, the adsorption of water molecules interacting with an op

The point of zero charge of three typical oxides found as colloids in PWR primary circuits has been measured by mass titration in a large range of temperature: from 5 to 320 °C for magnetite and cobalt ferrite, from 5 to 125 °C for nickel ferrite.

In this paper, geometric bulk parameters, bulk moduli, energy gaps and relative stabilities of the TiO2 anatase and rutile phases were determined from periodic DFT calculations. Then, for the rutile phase, structures, relaxations and surface energies

XPS and periodic DFT calculations have been used to investigate water sorption on the TiO2 rutile (1 1 0) face. Two sets of XPS spectra were collected on the TiO2 (1 1 0) single crystal clean and previously exposed to water: the first set with photoe

The sorption of Eu(III) onto kaolinite and montmorillonite was investigated up to 150 °C. The clays were purified samples, saturated with Na in the case of montmorillonite. Batch experiments were conducted at 25, 40, 80 and 150 °C in 0.5 M NaClO4 s

The sorption of Si on various iron corrosion products of nuclear waste canisters (magnetite Fe3O4, goethite a-FeOOH, and siderite FeCO3) and pyrite FeS2 was evidenced in the presence of a background electrolyte (NaCl or NaClO4). For magnetite, goethi
