Catalytic Mechanism of CO2 Reduction by Keggin-Type Transition-Metal-Substituted Polyoxometalates
Abstract The mechanisms of carbon dioxide reduction catalyzed by Keggin-type transition-metal-substituted polyoxometalates (TMSPOMs) have been studied by density functional theory calculations. CO2 is sufficiently activated via side-on adsorption in which the one oxygen and carbo...

ABSTRACT Afterglow luminescence probes are limited by (i) a lack of new afterglow scaffolds; (ii) a dependence on initial external light activation, and (iii) aggregation‐caused quenching. Herein, we demonstrate for the first time that Ir(III) complexes of general formula Ir(C^N)...

Exploring the complexity of students’ inconsistent relational understanding of the equal sign
Abstract Students’ understanding of the equal sign is a well-researched topic. Recently, some new insights come to emerge. One is the phenomenon of students holding simultaneous operational and relational understanding (SOR). Researcher called for more investigation to this pheno...

Machine learning enhanced microwave electrometry in many-body Rydberg atoms
Precision microwave electrometry using Rydberg atoms is limited by many-body interactions at moderate or not too low excitation densities, which may result in distorted probe spectra of electromagnetically induced transparency (EIT) as predicted by mean-field superatom simulation...

Population genomics reveals ginseng domestication and ginsenoside biosynthesis
Ginseng ( Panax ginseng ), a valuable medicinal plant, is cultivated for the bioactive ginsenosides with cardiovascular protective effects that are abundant in its roots. However, the genetic basis of its domestication and ginsenoside variation is not fully understood. In this st...

Harmony or Conflict? Grandparent–Parent Co‐Parenting Patterns and Children's Problematic Media Use
ABSTRACT Background Grandparent–parent co‐parenting is common in China, but its link to preschoolers' problematic media use is unclear. This study examined how co‐parenting patterns are associated with children's media use, focusing on the mediating role of parental digital paren...
