Equilibrium Distributions of Actinides and Lanthanides in Molten Salt and Liquid Metal Binary Phase Systems [PDF]

, 2010
application/pdfIn support of the development of a pyrochemical group partitioning process of actinides and lanthanides, the equilibrium distributions of these elements were measured in some binary phase systems of molten salt and liquid metal.

Thermodynamics of Concomitant Charge‐Transfer, Antiferromagnetic, and Isostructural Phase Transitions in Barocaloric ACu3Fe4O12 Quadruple Perovskites

Advanced Science, EarlyView.
A copper‐iron charge transfer instability drives concomitant electronic, magnetic, and isostructural phase transitions in ACu3Fe4O12${\rm ACu}_3{\rm Fe}_4{\rm O}_{12}$, with an inverse barocaloric effect. A minimal Landau theory ties these thermodynamic signatures together, revealing a pressure‐independent transition entropy with comparable charge and ...

Xenotime from Morrua, Mozambique [PDF]

Bulletin of the Geological Society of Finland, 1973
Xenotime, found as well formed crystals in a heavy mineral concentrate from the Morrua pegmatite mine in Mozambique, was studied. The mineral occurs in the sample in two generations, clearly distinguishable from each other.

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically

Dopaminergic- and Serotonergic-Dependent Behaviors Are Altered by Lanthanide Series Metals in Caenorhabditis elegans

Toxics
The lanthanide series elements are transition metals used as critical components of electronics, as well as rechargeable batteries, fertilizers, antimicrobials, contrast agents for medical imaging, and diesel fuel additives.

ABUNDANCES OF r-PROCESS ELEMENTS IN THE PHOTOSPHERE OF RED SUPERGIANT STAR PMMR23 IN SMALL MAGELLANIC CLOUD

Odessa Astronomical Publications, 2017
Detailed analysis of chemical abundances determined from high-resolution CCD-spectrogram of supergiant star PMMR23 (K5 I) in SMC is presented. The observation were obtained at 3.6 meter ESO La Silla telescope by Hill (1997).

From Lanthanides to Radioactivity

, 2013
This paper describes the step by step journey of explaining the Lanthanides, the Ytterbium jump, the relocation of the Helium electron pair around the nucleus and the final result of radioactivity.  Believe it or not, the incidents are all related.

Feasibility of the electrochemical way in molten fluorides for separating Thorium and Lanthanides and extracting Lanthanides from the solvent. [PDF]

, 2007
An alternative way of reprocessing nuclear fuel by hydrometallurgy could be using treatment with molten salts, particularly fluoride melts. Moreover, one of the six concepts chosen for GEN IV nuclear reactors (Technology Roadmap – http://gif.inel.gov ...

Supramolecular Terbium‐Threonine Chiral Emitters with Tunable Circularly Polarized Luminescence as Anticounterfeiting‐Ink for Autonomous Data Encryption

Advanced Science, EarlyView.
A one‐pot, aqueous, and scalable method for synthesizing chiral lanthanide supramolecular emitters using terbium and threonine is reported. The aqueous solution of these chiral emitters displays the following features: (i) 100 % transparency, (ii) tunable luminescence and CPL, and (iii) a pH feedback loop that controls the “on‐off” states of ...

Precisely Regulating 2.45 s Pure Blue Room‐Temperature Phosphorescence via Supramolecular Coordination

Advanced Science, EarlyView.
Herein, a pure deep blue room‐temperature phosphorescence (415 nm) with lifetime up to 2.45 s is successfully achieved by a covalently crosslinking purely organic material based on boric acid (BA) and 3,5‐dicarboxyphenylboronic acid (BOP) through a simple dehydration reaction, which can be adjusted precisely by supramolecular coordination with ...
