Resume: The extn. of rare earth elements (REEs) from nitric acid soln. with a triphosphine trioxide (TPO) is presented. Performances of such a ligand in ionic liqs. vs. a classical solvent (benzyl ether) are compared. TPO seems to be 10 to 100 times more efficient when it is dissolved in ionic media whatever the concn. of nitric acid involved. Mechanistic investigations reveal that cation exchange classically obsd. in ionic liqs. is not consistent with the exptl. data. Moreover, clear differences in the TPO/Ln complexes between classical and ionic media are highlighted. A stable complex of 1 lanthanide for 3 TPO is formed in an ionic liq. whereas a complex of 1 lanthanide for 6 to 9 TPO is formed in benzyl ether. Back extn. is also studied and good recovery of REEs could be obtained. The TPO/ionic liq. system shows remarkable performances i.e. efficiency and selectivity towards lanthanides in a simulated leaching soln. of a Nd/Fe/B/Dy magnet. [on SciFinder(R)]

Resume: Abstract Template-free electrodeposition of Te one-dimensional (1 D) nanostructures was carried out from an ionic liquid binary mixture: 1-ethyl-1-octyl-piperidinium bis(trifluoromethylsulfonyl)imide:1-ethyl-1-octyl-piperidinium bromide (EOPipTFSI:EOPipBr 95:5 (mol%)). SAED and XRD analyses confirm the formation of Te 1D nanostructures with a hexagonal single crystalline structure following the [001] direction. A systematic study of the influence of synthesis parameters on the deposits morphology has shown that it is possible to control the shape and the dimensions of the deposited nanostructures. Specifically, the applied potential has a strong influence on the morphology of the deposits. Nanowires or hollow nanostructures can be obtained, depending on mass transport conditions, as confirmed by the use of a soluble anode.

Resume: Metallophyte plants derived from phytoextn. are used as starting materials to prep. novel polymetallic catalysts. Polymetallic catalyst activity is used in many Lewis acid catalyzed reactions according to the polymetallic catalyst prepn. The synergetic catalysis of these systems leads to efficient syntheses of complex biomols. such as dihydropyrimidinone, 5'-capped DNA and RNA, and glycosyl aminoacid. These new polymetallic catalysts also bring new possibilities in Green Catalysis, that we named "Ecol. Catalysis". [on SciFinder(R)]
