Uranium immobilization by FEBEX bentonite and steel barriers in hydrothermal conditions
(Elsevier, 2015)
FEBEX clay is considered a reference material in engineered barriers for safe storage of nuclear waste and uranium is a minor component of high-level radioactive waste (HLRW) and a main component of the spent nuclear fuel ...

Competitive effect of the metallic canister and clay barrier on the sorption of Eu3+ under subcritical conditions
(Elsevier, 2014)
An in depth knowledge and understanding of high activity radionuclide (HLRW) immobilization processes on the materials composing the engineered barrier (clay and metallic canister) is required to ensure the safety and the ...

A new route of synthesis of Na-Mica-4 from sodalite
(Elsevier, 2014)
Synthesis of Na-Mica-4 has been achieved by a ``mix and calcine¿¿ method using sodalite and magnesium fluoride as the only precursors. Previous research found sodalite as a key intermediate reaction product in the formation ...

Application of the solid state NMR to the study of the alcohol/alkane mixtures adsorption onto graphite
(Academic Press, 2011)
The mixing of molecules adsorbed from solution to different interfaces has both industrial and academic relevance and the mixing behaviour at the interface is a key to understanding for example, that the surface tension ...

Quantification and comparison of the reaction properties of FEBEX and MX-80 clays with saponite: Europium immobilisers under subcritical conditions
(Elsevier, 2014)
The evaluation of the retention mechanisms in FEBEX and MX-80 bentonites, selected as reference materials to construct engineered barriers, carries major implications in the safe storage of immobilisation capacity through ...

Interaction of Eu-isotopes with saponite as a component of the engineered barrier
(Elsevier, 2011)
Bentonite is accepted as the best clay material in the engineered barrier of deep geological repositories (DGRs) for radioactive waste disposal. In recent years, the interactions between a wide range of rare-earth (REE) ...

Synthesis temperature effect on Na-Mica-4 crystallinity and heteroatom distribution
(Elsevier, 2015)
The discovery of swelling brittle mica, Na-Mica-4, has been one of the most significant advances in the pursuit for a material with high ion-exchange capacity. For technical applications, the control of the phase evolution ...

Caracterización de Mecanismos de Retención de Actínidos en Materiales Silicatados
(Enresa, 2011)
La gestión de los residuos radiactivos de alta actividad (RRAA) requiere un sistema de retención que asegure su aislamiento de la biosfera el tiempo suficiente, centenares de miles de años, como para que su actividad ...

New insights into surface-functionalized swelling high charged micas: Their adsorption performance for non-ionic organic pollutants
(Elsevier, 2017)
The major components of the wastewater from the petroleum refineries are benzene, toluene and phenol and one of the techniques applied to the treatment of effluents is sorption using organo-functionalized clay. The materials ...

Effect of the crystal chemistry on the hydration mechanism of swelling micas
(Elsevier, 2017)
Swelling and dehydration under minor changes in temperature and water vapor pressure is an important property that clays and clay minerals exhibit. In particular, their interlayer space, the solid-water interface and the ...
