Dual-Modified C–Ce–Mn2O3 Heterostructured Anode Catalytic Layer with Ultrastable OER Performance in Concentrated H2SO4 for Sustainable Nonferrous Metal Electrodeposition来源：ACS PublicationsMn2O3 emerges as a viable anode catalytic layer candidate for nonferrous metal electrodeposition, yet its industrial adoption is hindered by acid-triggered structural collapse and Mn3+ overoxidation. Here, we demonstrate a heterointerfacial engineering strategy that integrates carbon scaffolding with Ce-doped Mn2O3 (C–Ce–Mn2O3), achieving high stability in concentrated sulfuric acid (160 g·L–1) under agg...

Alkali Metal Substitution-Induced Structural Transformation for RbREP2Se6 (RE = Gd, Tb, Dy) with Second-Harmonic Generation Responses来源：ACS PublicationsRare-earth (RE) chalcogenides have been extensively studied as infrared nonlinear optical (NLO) materials, and they demonstrate high potential as candidates with integrated performances; however, the subgroup of RE chalcophosphates has been rarely studied. Herein, three new quaternary RE selenophosphates, RbGdP2Se6 (1), RbTbP2Se6 (2), and RbDyP2Se6 (3), were synthesized using the reactive flux RbI-assisted RExOy–B–Se solid-state method. They cr...

Near-Ultraviolet-Induced Narrow-Band Emission Phosphors Eu3+-Activated YCa4O(BO3)3 for Backlight-Display and White Light-Emitting Diodes来源：ACS PublicationsDeveloping red emission materials with high efficiency, good thermal stability, and high color purity remains a challenge for phosphor-converted light-emitting diodes (LEDs) and backlight displays. Herein, Eu3+-doped YCa4O(BO3)3 (YCOB) phosphors with narrow-band red light emission were designed to meet simultaneously the above targets. All samples have strong red emission with high color purity under near-ultraviolet (NUV) excitation. The te...

Unraveling the Extraction and Complexation Trends of Rare-Earth Elements with a Nitrilotriacetamide Ligand 来源：ACS PublicationsThe nitrilotriacetamide n-octyl derivative ligand (NTAamide(n-Oct)) is promising for minor actinide/lanthanide separation, yet periodic trends in its extraction and complexation across the lanthanide series remained unclear. This study systematically investigated its behavior with trivalent rare-earth ions (Ln3+, Y3+, and Sc3+) using solvent extraction, 1H NMR titration, UV–vis spectrophotometric titration, microcalorimetric titration, single-crystal X-ray diffract...
