来源：X-MOLThe reaction of Ln chlorides with Na3[Ti(H2Citrate)2(HCitrate)]·9H2O (H4Citrate is citric acid) in hot water brings about two similar series of complexes having a defect-dicubane structure, [Ln2Ti2O2(H2O)6(H2Citrate)2(HCitrate)2]·nH2O (Ln = La (1), Ce (2), Nd (3); n = 6, and Eu (4), Gd (5), Tb (6), Dy (7), Ho (8); n = 7). In each series, the complexes are isostructural with each other. For the heavier lanthanides, Er and Yb, formation of coordination polymers built of defect-dicubane fragments was found. Solid-state thermolysis of the complexes 1–8 was studied by means of TGA...

来源：ACS PublicationsThe ability to tune material function through primary sequence is a defining feature of biological macromolecules, enabling precise control over structure and target interactions in complex aqueous environments. However, translating sequence–structure–function relationships to synthetic macromolecules is challenging due to their dispersity in sequence, conformation, and composition. Here, we report systematic studies of amphiphilic polymer chelators designed to probe how composition and patterning influence binding affinity and selectivity for rare earth elements (REEs), a s...

来源：X-MOLPermanent magnets are the fundamental component in the development of modern technology, with their applications extending to fields such as energy generation, transportation, communication, and medical imaging etc. Even though rare-earth transition-metal (RE-TM) intermetallic perform well, rare-earth sources have recently become a bottleneck, and research is being conducted in a number of different ways. To address these gaps, it is essential to explore new approaches to design and manufacture the permanent magnets with non-rare earth materials or reduced content of rare earth element...

来源：ACS PublicationsRare earth halide solid state electrolytes (SSEs) have been attracting wide interest recently. However, the high cost of rare earth resources and poor cycling performance in all-solid-state batteries (ASSBs) hinder their practical applications. In this work, two novel high-entropy rare earth halide electrolytes, Li2.6(Y,Ho,Er,Tm,Yb)Cl5.6 (HEE-1) and Li2.6(Y,Ho,Er,Tm,Yb)0.5Zr0.5Cl6.1 (HEE-2), were rationally designed. Both electrolytes use five specially selected rare earth elements to achieve good cost effectiveness. These two electrolytes show high ionic conductivities of 0...
