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...

Ultrathin Single-Helix Rare Earth Nanowires: Inorganic Analogues of RNA Conformation with High Mechanical Flexibility来源：ACS PublicationsChirality has always been fascinating, yet inorganic chiral structures, especially those with helical shapes, are underexplored due to synthesis challenges. Herein, we regulated the conformation of rare earth ultrathin nanowires (RE NWs) at the sub-nanometer scale, constructing single-helix NWs (HNWs) with RNA-like conformation. The formation of HNWs is attributed to chiral ligands influencing the directional growth via steric hindrance at low temperatures. Ba...
