来源：ACS PublicationsThe compound Sm3Ge5 adopts two modifications with Pearson symbols hP16 (AlB2-derivative) and oF64 (defect α-ThSi2-type) upon synthesis at ambient pressure. Synthesis at extreme conditions grants access to the modification oS32 (Pu3Pd5-type). High-pressure high-temperature treatment of prereacted element mixtures yields Pu3Pd5-type Sm3Ge5, space group Cmcm with lattice parameters a = 9.42813(9), b = 7.56296(7), and c = 9.67056(8) Å. The atomic arrangement refined from powder X-ray diffraction data is confirmed by transmission electron microscopy measurements. The c...

Synergistic Coupling of Antenna Effect and Schottky Junction in Tb-Doped Covalent Organic Framework for Enhanced Electrochemiluminescence Sening of Isobutyryl Fentanyl来源：ACS PublicationsRational design of both mechanistic pathways and material compositions is essential to advance COF-based electrochemiluminescence (ECL) systems. In this study, aggregation-induced emission covalent organic framework (AIE-COF) nanoprobes with excellent ECL performance were developed based on Tb3+-functionalized covalent organic framework (Tb@A-COF). The Tb@A-COF system demonstrates enhanced ECL performance throu...

来源：ACS PublicationsThe development of a catalyst exhibiting high resistance to SO2 and H2O, while demonstrating superior CO oxidation performance, is of significant importance for specific industrial applications. In this study, Cu and/or Pr doped OMS-2 catalysts were synthesized via a solvent-free method. Their CO oxidation efficiency, along with their resistance to H2O and SO2, was systematically evaluated under simulated flue gas conditions. The catalytic activity of the Pr10%/Cu5%-OMS-2 catalyst is much superior to that of other catalysts, where it achieved 71.8% CO conversion at 60 °...
