Polarization Engineering and Chemical Bond Reconstruction in Rare-Earth Hexagonal Manganite via Fe3+-Occupied B-Site Doping for Piezocatalytic Therapy and FerroptosisPiezocatalytic therapy has emerged as a noninvasive therapeutic strategy. However, its therapeutic effect is limited by the low separation efficiency of carriers (electrons and holes) in piezoelectric materials. Rare-earth hexagonal manganite materials might be good candidates for efficient piezocatalytic therapy because of their high piezoelectric response, Curie temperature, and relatively narrow optical bandgaps. Herein, we rep...

来源：ACS PublicationsThis work reports the fabrication of a novel electrochemical sensor leveraging reduced graphene oxide (rGO) modified with samarium oxide (Sm2O3) nanoparticles to enhance dopamine (DA) detection. The primary goal was to create a sensitive and selective platform capable of distinguishing DA in complex biological environments. The sensor was synthesized using a hydrothermal method to form rGO/Sm2O3 composites, followed by characterization employing scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), and high-resolution TEM (HR-TE...

Manipulating Local Electron Density of Fe Nanoclusters with Cerium Incorporation to Optimize Adsorption Behavior of N-Related Intermediates for Electrochemical Ammonia Synthesis from Nitrite来源：ACS PublicationsCluster-scale metal ensembles feature high atomic utilization characteristics, but their activity and selectivity toward the electrocatalytic nitrite reduction reaction (NO2RR) remain suboptimal. As conventional holders of 4f orbitals, rare earth elements, especially cerium, are drawing wide attention as efficient promoters for transition-metal-based materials. Herein, Ce is incorporated ...

Bi-, Tri- and Tetranuclear Rare Earth Metal Complexes with Arylboronic Acids: Synthesis, Structure, and Photoluminescent Properties来源：ACS PublicationsPolynuclear complexes of rare earth metals Sc, La, Nd, Sm, Er, Yb with anthracenylboronic acid (AntB(OH)2) and pyrenylboronic acid (PyrB(OH)2) as a ligands were synthesized by reactions of cyclopentadienyl metal complexes LnCp3 with the corresponding arylboronic acid. X-ray structural analysis of Nd, Sm and Er complexes revealed that obtained compounds are dimers, in which each metal atom is coordinated by two terminal Cp ligands and two bridging...
