来源：ACS PublicationsMalonate ligands demonstrate versatility for intercalating metal complexes into layered rare-earth hydroxides (LREHs), enabling controlled tuning of coordination geometry and composition. As a proof of concept, a series of copper(II) malonate complexes with various substituents was synthesized and successfully intercalated into layered yttrium, europium, or terbium hydroxide at room temperature via anion-exchange reactions. The copper content in these hybrid materials increased in the order: butylmalonate

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...
