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...

来源：ACS PublicationsRecovering rare earth (RE) ions from mining wastewater offers several advantages, including reducing resource scarcity, minimizing environmental pollution, and lowering biological toxicity hazards. In this study, we synthesized a green adsorbent material, potato starch-derived β-cyclodextrin nanosponges (β-CD@PCPP NSs), via ionic cross-linking of β-cyclodextrin (β-CD), functionalized polyethylenimine (PEI), potato starch (PS), and chitosan (CS). The β-CD@PCPP NSs demonstrated favorable selectivity for cerium (Ce3+) and holmium (Ho3+), achieving maximum adsorption capacities ...

来源：ACS PublicationsAmbient electrochemical production of rare earth metals (REMs) in organic electrolytes has emerged as a promising alternative to conventional high-temperature and chemically intensive processes. Over the past two decades, a limited number of research groups have demonstrated the feasibility of REM electrodeposition under room temperature conditions. However, practical implementation remains limited by challenges in metal stability, selectivity, electrolyte performance, and scalability. This perspective critically assesses reported ambient REM electrochemical systems, includi...

来源：ACS PublicationsHere, we present our synthesis and characterization of the LnTi3(Sb,Sn)4 (Ln: Ce, Pr, Nd, Sm, Gd) family of cleavable kagome metals. While these materials are isostructural to the LnTi3Bi4 family, they only form as (Sb,Sn) solid-solutions with no corresponding LnTi3Sb4 or LnTi3Sn4 phases. We use a combination of first-principles density functional theory (DFT) and crystal orbital Hamilton population (COHP) calculations to show that (Sb,Sn) alloying has a stabilizing effect on the structure by adjusting the Fermi level, filling bonding states, depopulating antibonding states,...
