Magnetic NaA Zeolites Synthesized from Dual Solid Wastes Enables Selective Efficient Recovery of Rare Earth Ions from Neodymium Iron Boron Electroplating Wastewater来源：ACS PublicationsThis research leverages the minor iron oxides and carbon contained in Bayan Obo tailings (BOT) and coal gangue for the synthesis of magnetic zeolite NaA, which was subsequently applied to recover and separate rare earth elements (REEs) from Nd–Fe–B passivation solutions. To control the synthesis conditions of the magnetic zeolite, the effects of different raw material ratios, silicon/aluminum ratios, alkali fusion...

Defect Structure and Anion Conduction in Lanthanum Oxychloride Solid Solutions Revealed by X-ray Excited Optical Luminescence and Auger Emission来源：ACS PublicationsIon transport in crystalline solids is governed by the interplay between mobile ions and the host framework; ion mobility is facilitated by local structural distortions, dynamical evolution in the local coordination environment of the mobile ion, and coupling with lattice phonons. Ion dynamics are strongly influenced by the size and hardness of the mobile ion and the rigidity and polarizability of the host framework, as well as by th...

来源：ACS PublicationsMetal cation doping in hybrid perovskite semiconductors is one of the most effective approaches for tailoring their optoelectronic properties. However, their location-dependent functional mechanisms within the photoactive layer of perovskite solar cells (PSCs) remain poorly understood. Herein, we report that redox-stable samarium cations (Sm3+) enhance the performance of the PSC via partial substitution of lead ions (Pb2+). The optimized concentration of Sm3+ (5%) modulates the crystal quality, defect density, and charge carrier behavior of the perovskite layer. As a result,...

Crystalline Order Yet Glass-Like Heat Transport Driven by Hidden Local Distortions as the Structural Origin of Ultralow Thermal Conductivity in AgErTe2来源：ACS PublicationsGiven their rich chemical diversity and the interplay among the p-, d-, and f-orbitals of chalcogens, transition metals, and lanthanides, respectively, rare-earth transition-metal chalcogenides exhibit a wide variety of structural, magnetic, and transport phenomena. As a result, they form a particularly appealing platform for investigating structure–property relationships, emergent electronic and magnetic behaviors, and therma...
