Engineering Mn Atomic Sites in Multi-Dimensional Nitrogen-Doped Carbon for Highly Efficient Oxygen Reduction Reaction

Nitrogen-coordinated single-atom manganese in multi-dimensional nitrogen-doped carbon electrocatalysts (Mn-NC) was successful constructed by combing two-dimensional nanosheets and one-dimensional nanofibers. The Mn-NC exhibited excellent oxygen reduction reaction catalytic activity with half-wave...

Zn-Catalyzed Enantioselective Allylation and Allenylation of Isatins by virtue of Proline-derived Chiral Ligand

An asymmetric allylation and allenylation of isatins with facile organoboron reagents was developed under the catalysis of Lewis acid. A series of optically pure 3-allyl-3-hydroxyoxindoles and 3-allenyl-3-hydroxyoxindoles can be obtained...

Guanidinium substitution-dependent phase transitions, ionic conductivity and dielectric properties of MAPbI3

Over the past few years of boosting studies in halide perovskites, the formulation of guanidinium (GA+)-containing compounds has been proven to be an excellent strategy. A system in particular, namely...

Shape-Tunable Polymeric Janus Nanoparticles with Hollow Cavities Derived from Polymerization Induced Self-Assembly Based Crosslinked Vesicles
