来源：ACS PublicationsSelective and eco-friendly separation and purification methods for rare earth elements (REEs) are necessary to meet the increasing demand for these valuable metals, which are extensively used in modern electronics and clean energy technologies. Mining feedstocks consist of REE mixtures as stable trivalent cations (Ln3+) that are difficult to separate due to their identical charge and similar size. Lanthanide-binding tags (LBTs), peptide chelates that coordinate Ln3+ in binding pockets, show promise as selective, high-affinity extractants. We demonstrate that the LBT variant ...

Exploring Spin Hall Conductivity and Tunable Magnetoresistance in the Rare-Earth Topological Antiferromagnetic Dirac Semimetal GdCuSn 来源：ACS PublicationsMagnetic topological materials, driven by their nontrivial electronic structures, can give rise to exotic physical properties such as spin Hall conductivity and large magnetoresistance (LMR), holding promise for technological advancements that could revolutionize data storage technologies and magnetic sensors. In this study, we investigate the structural, magnetic, electronic, and dynamical properties of the equiatomic (1:1:1) rare-earth inter...

来源：ACS PublicationsThe unique physicochemical properties of rare earth elements (REEs) make them imperative for the production and improvement of advanced technology, renewable energy, and national defense applications. As these fields rapidly develop, there has been an increase in the demand for REEs. Due to the similar ionic charge and radii of adjacent REEs it is a challenge to selectively recover individual elements. Currently, the most common method for industrial REE separation is multistep traditional liquid–liquid extraction (T-LLE) systems. However, these systems generate large quanti...

来源：ACS PublicationsPyrroloquinoline quinone (PQQ)-binding proteins are found in diverse species and play key roles in the central metabolism of many methylotrophic bacteria, acting as redox-active cofactors in their alcohol dehydrogenase (ADH) enzymes. These enzymes also require a Lewis acidic metal ion to activate PQQ, and the 2011 discovery of lanthanide (Ln3+)-dependent ADH enzymes sparked a surge of interest in understanding their functional properties. However, key questions remain regarding the mechanism, metal ion-dependence, and electron transport processes of these enzymes. We report ...
