Rare-Earth Metal Modified Co-Based Catalysts for Highly Selective Hydrogenation of Furfural to 1,5-Pentanediol source:ACS PublicationThe ability to effectively control furan ring opening is the key to transforming furfural into 1,5-pentanediol. Herein, a series of Co-based catalysts modified with rare-earth metals (Y, Pr, La, and Ce) were synthesized. It was found that Y-modified Co-based catalyst with a Co/Y molar ratio of 3.5/0.5 exhibited the highest selectivity for 1,5-pentanediol (53.7%) at 150 °C and 4 MPa H2 in isopropanol (time = 5 h). Coordination between Co and Y in the cat...

Mechanisms and Origins of Regioselectivity in Rare-Earth-Catalyzed C–H Functionalization of Anisoles and Thioanisoles source:ACS PubicationsThe direct catalytic C–H functionalization of aromatic compounds such as anisoles and thioanisoles is of great interest and significance. However, achieving precise regioselectivity remains a major challenge. In this study, we conducted comprehensive density functional theory calculations to explore the mechanisms of rare-earth-catalyzed regioselective C–H alkylation, borylation, and silylation of anisole and thioanisole. The results reveal that in ca...

source:Nature CommunicationsThe biotransformation of nanoparticles plays a crucial role in determining their biological fate and responses. Although a few engineering strategies (e.g., surface functionalization and shape control) have been employed to regulate the fate of nanoparticles, the genetic control of nanoparticle biotransformation remains an unexplored avenue. Herein, we utilized a CRISPR-based genome-scale knockout approach to identify genes involved in the biotransformation of rare earth oxide (REO) nanoparticles. We found that the biotransformation of REOs in lysosomes could be gen...

Engineering Trap Distribution by Doping Rare Earth Ion for Mechanoluminescence Enhancementsource:ACSPublicationsMechanoluminescence materials exhibit fascinating optical properties due to their energy harvesting and controllable release capabilities. SrAl2O4:Eu2+ (SAOE) has been extensively studied as a traditional mechanoluminescence material, however, the luminescence intensity enhancement and the luminescence mechanism of its mechanoluminescence remain an unresolved issue, which hinders the development and widespread application of excellent phosphors. Herein, a promising rare earth (Re3+ =...
