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 °...

来源：ACS PublicationsRare-earth ion (Pr3+, Nd3+, and Tm3+)-doped yttrium vanadate (YVO4) crystals have aroused great research interest owing to their excellent laser performances. However, the microstructures, which underlie the optical properties of these crystals, are still unclear. In this paper, the stable crystal structures of the YVO4:Re (Re = Pr, Nd, and Tm) systems are predicted by using the crystal structure analysis by the particle swarm optimization (CALYPSO) structure search method. The unique tetragonal structures with the P4̅m2 (no. 115) space group for the YVO4:Re crystals are ide...
