Experimental and theoretical study of the behavior of hydrogen in rare earths
(Pergamon-Elsevier Science Ltd, 2005-05-13)
In this work, we study the behavior of hydrogen in some rare earths lanthanum (La), cerium (Ce), lutetium (Lu), and in two of its chemical precursors, scandium (Sc) and ytrium (Y). In the experimental aspect, samples of ...
Reviewing rare earth succinate frameworks from the reticular chemistry point of view: structures, nets, catalytic and photoluminescence applications
(Science From Israel-division Of Laser Pages Publ Ltd, 2018-10)
The intense development that Metal-Organic Frameworks have experienced along the last two decades, reflects the interest on these compounds as a new generation of multifunctional materials with diverse applications. The ...
Enrichment method for trace amounts of rare earth elements using chemofiltration and XRF determination
(Springer Verlag Berlín, 2000-10)
A preconcentration method for subsequent determination of rare earth elements (REE) by X-ray fluorescence (XRF) spectrometry was developed. The method is based on using (o-[3,6-disulfo-2-hydroxy-l-naphthylazo]-benzenearsonic ...
Geochemistry of rare earth elements in early-diagenetic miocene phosphatic concretions of Patagonia, Argentina: Phosphogenetic implications
(Pergamon-Elsevier Science Ltd, 2007-06)
Phosphatic concretions in the Early Miocene, shallow marine, clastic deposits of the Gaiman Formation (Gaiman Fm.) show typical major element ratios, rare earth element (REE) patterns, and total REE contents. These ...
A Panoramic Overview of Chlorination and Carbochlorination of Light Rare Earth Oxides, Including Thermodynamic, Reaction Mechanism, and Kinetic Aspects
(Springer, 2021-12)
Chlorination and carbochlorination processes have industrial applications in metallurgical activity for extraction and purification of uncommon metals such as rare earth elements (REE). This study reviews the chlorination ...
Preconcentration and elimination of matrix effects in XRF determinations of rare earth elements by preparing a thin film through chemofiltration
(Royal Society of Chemistry, 2001-02-20)
Trace rare earth elements (REE) can be enriched by collecting them on a filter after they have formed their complexes with 2,2′-(1,8-dihydroxy-3,6-disulfonaphthylene-2,7-bisazo) bisbenzenearsonic acid (Arsenazo III) through ...
Sensing properties, energy transfer mechanism and tuneable particle size processing of luminescent two-dimensional rare earth coordination networks
(Royal Society of Chemistry, 2017-01)
A new isostructural family of layered coordination networks (CNs) based on rare earth elements and mixed ligands was hydrothermally synthesized and fully characterized. The set of compounds with the general formula ...
Radioluminescence of rare-earth doped potassium yttrium fluorides crystals
(Pergamon-Elsevier Science Ltd, 2011-12)
The radioluminescence (RL) properties of K2YF5 crystals doped with Ce3+, Tb3+ and Dy3+ under ionizing irradiation excitation have been studied for the first time. The main objective of this work has been to assess the ...
Volume and heat of solution of hydrogen in rare earths from proton screening charges
(Pergamon-Elsevier Science Ltd, 2006-08)
In this work we determine some fundamental microscopic and macroscopic properties of rare earth-hydrogen (RE-H) systems. The behaviour of the electronic density variation of RE-H systems is obtained, using a program based ...
Structural study of decrespignyite-(Y), a complex yttrium rare earth copper carbonate chloride, by three-dimensional electron and synchrotron powder diffraction
(E Schweizerbartsche Verlags, 2020-10)
The crystal structure of the mineral decrespignyite-(Y) from the Paratoo copper mine (South Australia) has been obtained by applying d recycling direct methods to 3D electron diffraction (ED) data followed by Rietveld ...
