Synthesis, Structure, and Property of Tris(biphenyldiyl)yttrium(III) Tris(binaphthyldiyl)yttrium(III) and Tris(binaphthyldiyl)erbium(III) Complexes 来源：ACS PublicationsIn the recent development of homoleptic σ-hydrocarbyl rare-earth metal complexes focusing on reactivity and catalytic activity, rare-earth metal complexes with a variety of alkyl ligands have been synthesized, and the principle for designing thermally stable σ-hydrocarbyl rare-earth metal complexes has been established. Nevertheless, there has been no report of homoleptic rare-earth metal complexes comprising only identical ...

来源：ACS PulicationsCerium oxide thin films represent an important approach to hydrophobic, self-cleaning solar modules, offering significant potential for photovoltaic applications. These coatings provide a durable, long-lasting alternative to conventional self-cleaning surface technologies, which often rely on polymer-based films prone to degradation over time. Here, we present the synthesis of tetrakis(2,2,6,6-tetramethyl-3,5-heptanedionate) cerium ([Ce(thd)4]) for the deposition of hydrophobic cerium oxide thin films by aerosol-assisted chemical vapor deposition (AACVD). The use of [Ce(thd)4...

Controlling Selectivity of Surface Electro-Precipitation (SEP) in the Recovery of Rare Earth Elements (REE) from Aqueous Feedstocks 来源：ACS PublicationsSEP is an emerging green separation technique for the recovery of REE and other valuable elements from unconventional feedstocks. Its industrial adoption requires comprehensive mechanistic knowledge of its selectivity for REE vs typical background cations to achieve the desired separation. To bridge this gap, we experimentally studied SEP of neodymium Nd in chloride, nitrate, and sulfate solutions, in the absence and presence of calcium, al...

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 ...
