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...

A novel extraction model optimization with effective separation coefficient for rare earth extraction process using improve differential evolution source:scientific reportsThe mechanistic model of the rare earth extraction process neglects the efficacy of the agitator within the extraction extractor. This oversight results in a significant discrepancy between the theoretical solute concentration at each stage and the actual process data. To rectify this issue, we introduce an effective separation coefficient, thereby enabling the creation of a model capable of accurately determining the c...
