来源：X-MOLLanthanides (Ln) offer rich and otherwise unusual chemistry, which includes their redox behavior, ligand coordination, diverse quantum phenomena, etc. Unlike the lighter elements, these f-block elements could exhibit nonlinear trends in various chemical and physical properties across the series with a noticeable break often being observed in the central atom gadolinium (Gd). This popular notion of “Gd break” has been challenged and banished by researchers in the past, making this as an ever-debated issue in the chemical fraternity. In this Letter, we examine the solvation behavior of d...

来源：ACS PublicationsMXenes have become one of the most versatile families of two-dimensional (2D) materials due to their high conductivity, hydrophilicity, and remarkable electrochemical performance. This has stimulated intense efforts to design and synthesize MXenes, including structurally unique in-plane ordered 2D MXenes called i-MXenes. Here, we have synthesized the quaternary rare earth (RE)-based i-MAX phase (Mo2/3Er1/3)2AlC using an arc melting method, and the corresponding 2D i-MXene was then obtained through a LiF/HCl soft etching process. Literature studies have shown that Al and the ...

来源：ACS PublicationsMagnetic separations present a promising approach for the recovery of rare earth (RE) elements from mixtures, particularly when coupled with precipitation techniques that enhance process efficiency and selectivity. However, the magnetic properties of RE materials typically encountered in the separations industry are not well characterized. Here, we synthesized a series of RE materials, combining four REs─praseodymium (Pr), neodymium (Nd), terbium (Tb), and dysprosium (Dy)─with three precipitating agents─hydroxide, oxalate, and dibutyl phosphate. All materials showed typical ...

来源：ACS PublicationsThe electronegativities of the rare-earth elements are proposed; these use average “relative valence electron binding energies” (ReVEBE) that are deduced from experimental spectroscopic data listed in the NIST Atomic Spectra Database. According to this concept, only the lowest-lying levels of the valence electron configurations are considered. These electronegativities were obtained as estimated binding energies based on a modified concept by Rahm, Zeng, and Hoffmann of ground-state average valence electron binding energies for the main group and transition metal elements. T...
