Optimized Flux Single-Crystal Growth of the Quantum Spin Liquid Candidate NdTa7O19 and Other Rare-Earth Heptatantalates, ErTa7O19 and GdTa7O19 来源：ACS PublicationsSingle crystals are essential for characterizing a wide range of magnetic states, including exotic ones such as quantum spin liquids. This study reports a flux method for growing single crystals of NdTa7O19, the first quantum spin liquid candidate on a triangular spin-lattice with dominant Ising-like spin correlations. Purple NdTa7O19 single crystals with hexagonal morphology were successfully grown by using a K2Mo3O10–B2O3 flux....

Crystal Growth of Quaternary Rare Earth Selenosilicates by Using the Flux-Assisted Boron Chalcogen Mixture Method: Investigation of Their Magnetic and Optical Properties来源：ACS PublicationsA series of rare earth magnesium selenosilicates, RE3Mg0.5SiSe7 (RE = Ce, Pr, Nd, Sm, Gd, Tb, Dy) were obtained as single crystal using the flux assisted boron chalcogen mixture (BCM) method. The structures of the crystals were determined by single-crystal X-ray diffraction. The RE3Mg0.5SiSe7 series crystallizes in the hexagonal crystal system in the space group P63. Polycrystalline powders were synthesized t...

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...
