来源：ACS PublicationsPhotoacoustic imaging (PAI) has emerged as a promising noninvasive biomedical imaging modality with high spatial resolution and soft tissue contrast. Exogenous contrast agents play a crucial role in enhancing the sensitivity and specificity of PAI. Among these contrast agents, the rare earth materials (REM) have garnered a lot of interest due to their near-infrared (NIR) absorption properties. REM established itself as a well-known entity in the field of bioimaging and therapy due to their optical, magnetic, and photothermal characteristics. The photoacoustic phenomenon of R...

来源：ACS PublicationsAs the importance of rare earth metals in high-tech equipment and defense industries continues to increase, optimizing the performance of rare earth electrolytic cells has become increasingly crucial for enhancing energy efficiency and production effectiveness. Based on the issue of gas stagnation at the anode bottom in the bottom cathode rare earth electrolytic cells, this study proposes an optimized anode structure aiming to improve bubble emission, flow field characteristics, and the stability of the electrolysis process. The bubble dynamics and flow field characteristics...

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...
