来源：ACS PublicationsRare earth elements (REEs) are critical components in emerging technologies, but their mining and refining processes are often laborious, costly, and environmentally damaging. Developing green and efficient separation methods for REEs is crucial. Biomolecular approaches using lanthanide-binding proteins and peptides show promise for selective REE extraction and separation. In this study, we present the design and characterization of a genetically encoded fluorescence indicator (GEFI) construct that combines a superfolder green fluorescent protein (sfGFP) with a dual lanthani...

来源：ACS PublicationsIn this work, BaCl2:Eu2+,S2– is employed as model system to investigate the formation and tunable evolution of localized excitonic magnetic polarons (LEMPs) in Eu–S codoped divalent metal halides, in which Eu–S bonding in BaCl2 with Eu2+ 5d–f hybridization markedly enhances the band edge emission, shifting from 401 to 412 nm with rising EuS content, and the absorption band edge shifts from 3.02 to 2.85 eV, with EMP character. Moreover, EuS doped in different hosts (Ba Sr Ca) leads to a progressive red shift of EMP emission from 406 nm to the near-infrared region. Under hig...

来源：ACS PublicationsDry reforming of methane (DRM) offers a promising strategy that concomitantly converts two greenhouse gases (CH4 and CO2) into valuable syngas (H2 and CO). Ni is a commonly used active metal component in DRM catalysts, while catalyst deactivation stemming from carbon accumulation and sintering remains a great challenge. Ensuring the availability of adequate active oxygen species to promote CHx (x = 0∼3) oxidation and inhibit particle aggregation is generally critical to prevent catalyst deactivation. Our study applied a simple coprecipitation method to synthesize Ni/CexMgO c...

来源：ACS PublicationsOptical quantum memories enable long-distance quantum information distribution, which is critical for establishing the global quantum Internet. Rare-earth qubits are promising candidates due to their spin-optical interfaces with excellent spin coherence and optical properties. When doped into inorganic solids, they display relatively long excited-state lifetimes and, in turn, low storage efficiencies, which are difficult to optimize via material design. Metal–organic frameworks (MOFs) allow fine-tuning of spin coherence and excited-state lifetimes through rational design of ...
