Crown Ethers in the Group and Individual Separation of Rare-Earth Elements through Solvent Extraction: Interactions, Thermodynamics, and Applications Rare-earth elements (REEs) have a pivotal role in modern technology due to their distinctive physicochemical properties. Solvent extraction is a widely used industrial method for separating REEs from pregnant leach solutions. Crown ethers (CEs) have shown notable selectivity and affinity for REEs and alkali-metal ions. Notable CEs include 15-crown-5, 12-crown-4, 18-crown-6, and dibenzo-18-crown-6 ligands and are employed in both organic and ...

Crystalline Phase Induction Strategy for the Design of Luminescent Lanthanide Coordination Polymers: Toward Plastic Waste Recycling 来源：ACS PublicationsReactions in water between a lanthanide chloride and the disodium salt of tetrachloro-phthalate (tcpa2–) lead to a family of isostructural coordination polymers with the general chemical formula [Ln2(tcpa)3(H2O)4]∞ with Ln = La–Pr (Family 2, F2). The crystal structure was solved based on the La-derivative. It crystallizes in the monoclinic system, space group P21/n (n°14) with the following cell parameters: a = 6.2491(3) Å, b = 17...

来源：ACS PublicationsOptically addressable spin impurities in crystals along with device engineering provide an attractive route to realizing quantum technologies in the solid state, but reconciling disparate emitter and host material constraints for a given target application is often challenging. Rare-earth ions in two-dimensional (2D) materials could mitigate this problem given the atomic-like transitions of the emitters and the versatile nature of van der Waals systems. Here we combine ion implantation, confocal microscopy, and ab initio calculations to examine the photon emission of Er-dope...
