来源：ACS PublicationsThe wettability of rare earth oxides (REOs) including the lanthanide series, scandium, and yttrium has become a subject of increasing interest and debate. While many studies report hydrophobic behavior with high water contact angles, emerging evidence indicates that pristine REO surfaces are intrinsically hydrophilic, and that hydrophobicity arises primarily from extrinsic surface contamination by volatile organic compounds. This perspective examines the contrasting viewpoints on REO surface wettability, integrating insights from surface structure, electronic configura...

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 °...
