来源 ：ACS PublicationsMagnetic refrigeration using the magnetocaloric effect (MCE), where the temperature of a material changes as a magnetic field is applied, is a promising technology to increase the energy efficiency of commodity gas liquefaction at cryogenic temperatures. Currently, the most commonly studied materials for this application utilize rare-earth elements in nonporous forms. The continued development of magnetocaloric materials could benefit from (1) the discovery of materials with high surface areas capable of condensing substantial quantities of gas using minimal energy inputs a...

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 ...

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...
