来源：Science DirectThree new compounds with the composition NaLn9N4Se8 (Ln = Gd – Dy) could be synthesized and structurally characterized. Initially intended to achieve the ternary Ln4N2Se3 representatives, the involvement of sodium-containing reactants led to the formation of these quaternary phases. They crystallize in the monoclinic system with the space group C2/m (lattice parameters: a = 1358 – 1341 pm, b = 399 – 394 pm, c = 1016 – 1026 pm and β = 109.1 – 109.3°) and one formula unit per unit cell. A group-subgroup relationship of both mentioned compound types can be shown, describing ...

Cation Exchange Protocol to Radiolabel Rare-Earth Nanoparticles with Yttrium-90 for Radiotherapy and for Magnetic Resonance Imaging 来源：ACS PublicationsInternal radiation therapy (iRT) is an emerging therapeutic approach based on high-energy radionuclide implants categorized as alpha or beta particles placed directly into the tumor to induce cancer cell damage. This work focuses on the development of a unique approach for incorporating β-emitter yttrium-90 (90Y) radionuclides via a cation exchange method into lanthanide-based nanoparticles (NPs), consisting of NaLnF4 composition (Ln = Gd, ...

来源：ACS PublicationsA series of vanadium-doped orthoniobates of the type La(Nb1–xVx)O4 (x = 0.00–0.40) were synthesized using a solid-state method, and their long-range average and short-range local structures comprehensively investigated using a combination of high-resolution neutron powder diffraction (NPD) and synchrotron X-ray powder diffraction (S-XRD) that produced accurate and precise structures of several members of the series. The structures evolve from a monoclinic fergusonite-type to a tetragonal scheelite-type structure as the V content increases. Substituting Nb5+ by the smaller V5...

Synergistic Effects of Multimodal Polydopamine Coating on NaGdF4@NaYF4:Nd3+ Nanostructured Alginate Microspheres through the Combination of Chemotherapy and Photothermal Therapy 来源：ACS PublicationsNanophosphors have gained substantial attention in recent years for both the diagnosis and treatment of cancer. Near-infrared optical imaging based on Nd3+-doped rare-earth nanophosphors is widely used for deep penetration tissue imaging. The present work aims to develop a hierarchical structure of polydopamine (PDA)-coated alginate microspheres encapsulated with NaGdF4@NaYF4:Nd3+ and cisplatin ...
