Highly Water-Dispersible Upconverting GdPO4Er3+Yb3+ Nanophosphors for Optical, Magnetic, Magnetic Hyperthermia, Anticounterfeit, and In Vitro and Ex-Vivo Multimodal Applications来源：ACS PublicationsHighly water-dispersible Er3+/Yb3+-activated GdPO4 nanophosphors were synthesized via a polyol-mediated coprecipitation route. In situ X-ray diffraction reveals a thermally induced phase transformation from hexagonal to monoclinic symmetry upon annealing between 50 and 900 °C, accompanied by a morphology evolution from nanorods to dumbbell-like structures as confirmed by HRTEM (high resolution tr...

来源：ACS PublicationsCsPbBr3 perovskite nanocrystals have been investigated as photocatalysts for CO2 reduction owing to their excellent light-harvesting and multi-exciton generation. However, under strong illumination, Pb2+ migration and reduction to metallic Pb0 cause lattice collapse and accelerated carrier recombination, severely limiting their stability and photocatalytic performance. Here, we developed a dynamic valence regulation approach using Eu2+/Eu3+ redox couple to enhance lattice stability and improve photocatalytic performance by suppressing Pb2+ migration and Pb0 exsolution, modul...

来源：ACS PublicationsSecuring a sustainable supply of rare earth elements (REEs) requires efficient separation and recovery from secondary streams. Zeolites are attractive, low-impact sorbents; however, the atomistic origins of REE selectivity under hydrated conditions remain insufficiently resolved. Here, we combine high-resolution synchrotron X-ray powder diffraction (XRPD) with density functional theory (DFT) to elucidate the exchange and recovery mechanisms of Ce3+, La3+, Eu3+, and Y3+ in ammonium-exchanged faujasite X (NH4–X). Monoelement solutions mimicking the concentrations of leachates ...

Six-Core Ln-MOF Materials (Ln = La, Eu, Tb) Constructed from the Building Blocks [Ln4(COO)10] and [Ln4(COO)10(μ-H2O)] Based on In Situ Reactions and Their Multifunctional Fluorescence Sensor Behavior来源：ACS PublicationsLa-MOF complex with six metal cores was synthesized by an in situ reaction of terephthaloyl chloride and La(NO3)3·6H2O under solvothermal conditions. During the reaction process, it was surprisingly found that the terephthaloyl chloride was hydrolyzed into 1,4-H2BDC and then coordinated with La(NO3)3·6H2O to form a six-core metal–organic framework, complex 1, [La6(1,4-B...
