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,...

来源：ACS PublicationsScandium (Sc), as a critical rare earth element (REE), holds significant application value in advanced manufacturing, energy materials, catalysis, and other fields. However, due to the common coexistence of Sc with light and heavy REEs, which exhibit high similarities in ionic radius, valence state, and coordination chemistry, conventional spectrophotometric methods suffer from poor selectivity, making accurate quantification of Sc3+ in complex matrices difficult. In this study, we present a label-free ion sensing platform based on silicon nanowire-modified glass micropipett...

Coupling High-Throughput Density Functional Theory, Automated Experimentation, and Adaptive Experimental Design To Achieve Selective Rare-Earth Element Separations 来源：ACS PublicationsDeveloping new separation technologies for rare-earth elements is essential for sustaining the critical materials supply chain. Toward this end, we developed a pH-controlled solvent extraction strategy employing an aqueous-phase holdback agent to enable selective lanthanide separations, using an integrated computational, machine learning, and automated experimental high-throughput workflow. Database screening, den...
