Lanthanides — Phthalocyanines complexes : from a diphthalocyanine Pc
Lanthanide-phthalocyanine adducts PcyLnx have been synthetized for Ln = La, Nd, Eu, Gd, Dy, Yb and Lu. The analysis of their spectroscopic properties and of their behavior under chemical oxidation and reduction suggests that whereas a diphthalocyanine ...

Hydration counteracts the separation of lanthanides by solvent extraction
The extraction of lanthanides from aqueous nitrate solutions by quaternary ammonium nitrate ionic liquids (e.g., [A336][NO3]) shows a negative sequence (i.e., light lanthanides are more efficiently extracted than heavy lanthanides), which conflicts with ...

Luminescence and Photochromism in Lanthanide‐Doped Hackmanites
Lanthanide‐doped lithium hackmanite derivatives are prepared utilizing a doped LiAlSiO4 precursor to modify luminescent and photochromic properties. Upon UV excitation, europium doping results in green Eu2+ persistent luminescence from shallow traps. Contrarily, samarium doping induces unusual near‐infrared photochromism.

Lattice dynamics of lanthanides
Les fréquences de phonons des deux lanthanides Tb et Ho ont été calculées à partir du modèle de potentiel non local des métaux de terres rares d'upadhyaya et Animalu, qui prend en compte les termes linéaires en E et k.q dans le développement de Taylor du

A diluent‐free, customizable liquid–liquid phase separation (LLPS) platform enables highly efficient radioactive metal ion extraction and stripping. By encapsulating hydrophobic extractants into an ionic surfactant‐rich condensed phase, this LLPS system leverages synergistic electrostatic and coordination interactions.

Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs

A novel optical thermometer exploits the rare UV emission of Yb2+ ions in a SrB4O7 host, enabling highly sensitive, non‐contact temperature measurements from 80 to 420 K. The applied multiple linear regression (MLR) analysis results in a multiple increase in the resulting temperature sensitivity.

Reverse Weak Polarity‐Induced Ordered Layer Control strategy, optimizing the design of layered structures, has been successfully designed. By leveraging inhomogeneous field of units to replace isotropic fields of metal cations, polar layers realize controllable layer stacking via a “layer→linker→layer” polarity transfer.
