Stability of reverse micelles in rare-earth separation: a chemical model based on a molecular approach

A new molecular approach based on molecular dynamics simulations is proposed to investigate the stability of reverse micelles containing strategic metals in organic phase. 

From in Situ HT-ESEM Observations to Simulation: How Does Polycrystallinity Affects the Sintering of CeO2 Microspheres?

In situ observation of the first stage of sintering of cerium dioxide microspheres performed using an environmental scanning electron microscope at high temperature (HT-ESEM).

Incorporation of Thorium in the Zircon Structure Type through the Th1-xErx(SiO4)1-x(PO4)x Thorite–Xenotime Solid Solution

Pure Th1−xErx(SiO4)1−x(PO4)x compounds belonging to the zircon–xenotime family were synthesized under hydrothermal conditions (250 °C, 7 days).

Vitamin C boosts ceria-based catalyst recycling

The facile, rapid, and complete reductive dissolution of CeO2 and ceria-based oxides, known to be highly refractive materials towards dissolution, is reported for the first time in very mild conditions.

Performances and mechanistic investigations of a triphosphine trioxide/ionic liquid system for rare earth extraction

We demonstrated that the TPO/ionic liquid system showed remarkable performances, i.e., efficiency and selectivity towards lanthanides in a simulated leaching solution of a Nd/Fe/B/Dy magnet.

Solvent Extraction: Structure of the Liquid-Liquid Interface Containing a Diamide Ligand

We show for the first time that hard trivalent cations can be repelled or attracted by the extractant-enriched interface according to the nature of the ligand.

Technique haute résolution de la spectroscopie d'absorption de rayons X de haute énergie (HERFD-XAS)

Première illustration de la capacité de cette technique pour sonder directement l’influence du champ cristallin sur les orbitales de valence 5f et 6d de composés d’actinides.
