来源：X-MOLSubstitutional or interstitial metal-cation dopants in CeO2 play key roles in catalytic, sensing, and energy applications. Cation dopants with a valency less than 4+ create charge-compensating oxygen vacancies in the lattice that boost ionic conductivity and act as reactant adsorption/dissociation sites. These cation dopants also modify the optical properties of CeO2, enabling the normally high-bandgap oxide to more effectively harvest visible light. In this perspective, we highlight the key progress made using dopants in CeO2 and the challenges that remain. We briefly summarize common...

来源：ACS PublicationsHeterobimetallic rare-earth-nickel alkyl complexes (RE-Ni-alkyl) supported by an arene-anchored bis(phosphinomethylamido) ligand were synthesized and further reacted with MesPH2 (Mes = 2,4,6-trimethylphenyl) to afford rare-earth-nickel phosphido complexes (RE-Ni-PHMes). The phosphido complexes have exhibited insertion reactivity toward a variety of unsaturated substrates, including alkyne, carbodiimide, ketone, organic azide, and diazomethane, leading to the formation of a series of heterobimetallic rare-earth-nickel complexes with various functional ligands. On the other ha...

来源：ACS PublicationsRare earth elements (REEs) are essential for contemporary technologies; however, their sustainable recovery from aqueous media remains challenging due to limited reserves and the environmental impacts associated with conventional extraction methods. This study presents the synthesis of magnetically retrievable core@shell nanocomposites (MRCSNs) as an efficient platform for REE adsorption from water. The MRCSNs consist of a magnetic zerovalent iron nanoparticle core, a silica shell scaffold, and surface-attached functional ligands, including 3-aminopropyltriethoxysilane (NH2)...

来源：ACS PublicationsThe molten flux method was used to grow crystals belonging to two different classes of rare-earth hafnium molybdates, RE2Hf3(MoO4)9 and RE2Hf2(MoO4)7, whose luminescence and magnetic properties were investigated. The first structure type, RE2Hf3(MoO4)9, spans from La to Eu (except Pm) and crystallizes in the trigonal R-3c space group. In this structure, MoO4, REO9, and HfO6 are connected via their corners. The MoO4 units form open channels along the c-axis, which are occupied by columns of REO9 and HfO6 polyhedra. The second structure type, RE2Hf2(MoO4)7, includes RE = Sm, E...
