来源：ACS PublicationsThe oxygen evolution reaction (OER) is a critical yet kinetically sluggish process in water electrolysis for hydrogen generation, owing to its multistep, four-electron transfer. This necessitates the development of efficient catalysts to accelerate the reaction. Herein, Er/Fe-codoped Ni2P supported on nickel foam (Er/Fe−Ni2P/NF) was fabricated via an electrodeposition−phosphorization approach to explore the Er/Fe synergistic effects on OER dynamics. The results demonstrate that Er/Fe codoping effectively modulates the electronic structure of the catalyst and accelerates char...

New lanthanide coordination polymers (Ln-CPs) from 2-hydroxyterephthalate: Excited-state intramolecular proton transfer (ESIPT) and sensing capabilities来源：X-MOLEleven new coordination polymers (Ln-CPs), Ln2(htp)3(DMF)4∙x(DMF), where Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and htp = 2-hydroxyterephthalate were synthesized, structurally characterized and their photoluminescence properties studied. Time-dependent density-functional theory (TD-DFT) calculations were used to explain key differences and similarities in excitation and emission spectra of Ln2(htp)3(DMF)4∙x(DMF) (Ln = La (x = 2...

来源：ACS PublicationsUnderstanding the influence of processing routes on grain boundary structure and crystallographic texture is essential for optimizing the magnetic performance of nanocrystalline Nd–Fe–B magnets. In this study, a five-parameter crystallographic analysis was employed to systematically investigate the influence of spark plasma sintering and hot deformation sintering on the grain boundary plane distribution and crystallographic texture of nanocrystalline Nd–Fe–B magnets. Its reveals that the hot deformation process confers marked advantages in promoting strong c-axis texture and...

来源：ACS PublicationsThe rare-earth intermetallic compound NdCuSb2 possesses an antiferromagnetic (AFM) order below TN = 3.78 K, with magnetic moments aligned along the b axis. Here, we systematically investigate the pressure evolution of the structural and electronic properties of a NdCuSb2 single crystal up to 53.4 GPa. With initial increasing pressure, TN decreases rapidly and eventually vanishes above PC = 3.5 GPa, indicating the complete suppression of the pristine AFM state. Upon further compression to 6.0 GPa, a new anomaly, T*, around 4 K is observed and shows a monotonous increment with...
