来源：ACS PublicationsThe integration of diverse electronic phenomena, such as magnetism and nontrivial topology, into a single low-dimensional system gives rise to unusual quantum effects. Here we combine two 2D topological insulators, α-bismuthene and β-silicene, with a Ho monolayer. Bismuthene is synthesized within a rarely realized square-like lattice in the black phosphorus monolayer structure, and its interfacing with the silicene minimizes the unwanted hybridization with the Ho monolayer, thus facilitating a quasi-free-standing behavior. The spectroscopy observations together with ab initi...

来源：ACS PublicationsRare-earth elements (REEs: La–Lu, Y, Sc) are critical to modern technology; however, their acquisition, purification, and separation from each other can be challenging, and current methods are often environmentally damaging. Metal-binding polymers are a promising material class to improve these methods, but fundamental structure–property relationships have yet to be fully developed. Inspired by nature’s use of solvation- and conformation-driven effects to control metal-binding interactions, we hypothesized that modifying the molecular environment around the binding sites on ...

来源：ACS PublicationsThe synthesis of alkali-metal-free compounds [LnMe3]n is scrutinized using two distinct protocols. The donor-promoted cleavage of homoleptic tetramethylaluminate complexes Ln(AlMe4)3 proves rare-earth metal (Ln) size-dependent and gives access to [LnMe3]n (small to midsized Ln(III)) and [LnMe3-x(AlMe4)x(OEt2)y] (large Ln(III)). Both compounds can be converted to homoleptic tetramethylgallates Ln(GaMe4)3 by addition of trimethylgallium. Crystallization attempts of [LnMe3-x(AlMe4)x(OEt2)y] via extended donor-solvent treatment produced structural snapshots of a diverse set of c...

来源：ScienceDirectIn the in-situ leaching of ionic rare earth ores, ineffective through-flow induced by ore body heterogeneity and suboptimal rinsing strategies constrain both extraction efficiency and mine environmental sustainability. This study employed an experimentally validated pore-scale numerical model, reconstructed from nuclear magnetic resonance imaging, to elucidate magnesium ion transport mechanisms and optimize rinsing operations for enhanced in-situ leaching performance. Simulation results showed a three-stage transport pattern in magnesium ion migration through heterogeneous ore ...
