来源：ACS PublicationsPropyl gallate (PG) poses a potential threat to human health through dietary exposure. Herein, Eu3+/Y3+ was combined with dual ligands and biomass-derived nitrogen-doped carbon quantum dots (N-CDs) to synthesize multicomponent rare-earth metal–organic gels (N-CDs@Eu0.05Y0.95-DL-MOGs), achieving electrochemiluminescence (ECL) and fluorescence (FL) visual detection of PG. The dual ligands as antenna molecules collectively displace H2O coordination, which sensitizes Eu3+ via energy transfer. Theoretical calculations indicated that Y3+ regulates the molecular orbital energy leve...

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...
