Metal Extraction

"Solid/Liquid extraction : In-Situ precipitation of MOFs from aqueous waste solution"
Metal–Organic Frameworks (MOFs) are an emerging class of porous materials constructed from metal containing nodes and organic linkers with a particular high porosity, stability and easy tunability. These materials have shown promise for diverse applications including catalysis, sensing, separations, or even as light-harvesting materials.(1) Our interest is to ... Read more
"Fluorinated vs hydrogenated molecules: organic phase model systems"
Better understanding of how a metal ion usually not soluble in an organic phase can be maintained into it by using an extractant is one of the main challenges in the liquid-liquid separation field. One part of this challenge is to elucidate the role of the interactions which can take place at the molecular level (Fig. 1), ... Read more
"Liquid/Liquid Extraction of strategic metals (Rare earths, palladium...)"
Recycling of valuable metals appears nowadays as solution of growing interest for a sustainable supply strategy. Palladium (Pd), along with other platinum group metals (PGM) and rare earth elements (REEs), represent one of the crucial issues for recovery processes. Valuation of nitric effluents containing REEs and PGM is more and more envisioned, especially in the ... Read more

 

Energy

"Molecular Polymetallic Compounds for Photochemistry"
The increase of the energy demand and the limitation of the nature reserves of fossil fuels bring us to find new methods to produce and to store some energy. That’s why since a few decades, the scientists try to develop molecular systems inspired by functions realized by the nature (1,2). These systems require the association of several constituents molecular as a ... Read more

"Photo-responsive Metal Organic Framework (MOF)"
The sustainable production of energy is one of the most important scientific and technological challenges facing humanity. For that matter, light-driven photochemical reactions, such as water splitting and CO2 reduction with water, can transform sunlight energy into chemical energy. Designing an efficient organic/inorganic hybrid material that features molecular ... Read more
"Photocatalytic MOF on solid support"
MOFs have largely been prepared as crystalline powders and rarely as thin-film on a substrate (solid support). Generally, chemical deposition on support is focused on transparent conductive surfaces based on fluorine tin oxide (FTO) and indium tin oxide (ITO). Thin films composed of MOFs with photo response properties are of essential interest ... Read more

Toxicology

"Uranyl interaction with bone mimics"
Whatever its entry route into the body, the uranyl cation (UO22+) is sent through the blood to its target organs: kidneys, for rapid elimination, and skeleton, for long term sequestration. The accumulation of uranyl in bones leads to an increased bone resorption and/or and inhibition of bone formation. To limit this accumulation, and favour excretion as a soluble form, ... Read more
