来源：ACS PublicationsThe intrinsic instability of ruthenium dioxide (RuO2) under acidic oxygen evolution reaction (OER) conditions remains a critical challenge for the development of durable OER electrocatalysts. Here, we present an exploratory comparative half-cell investigation of one nominal Er/Y-modified RuO2 composition. Under the specified conditions (0.1 M HClO4, room temperature, three-electrode configuration), Er0.1Y0.1Ru0.8O2 required 226 mV to reach 10 mA cm–2, compared with 257 mV for identically prepared h-RuO2. During an 80,000 s chronopotentiometry test, the modified sample showed...

AgEuPS4: Unlocking the Centrosymmetric Shackle of Rare-Earth Thiophosphates via Microscopic Distortion Cascading for Enhanced Second-Harmonic Generation Response 来源：ACS PublicationsBreaking the rigid centrosymmetric (CS) shackles of rare-earth thiophosphates remains a significant challenge for designing high-performance mid-to-far-infrared (MFIR) nonlinear optical (NLO) materials. Herein, using the CS LiEuPS4 (I41/acd) as the structural template, a noncentrosymmetric (NCS) rare-earth thiophosphate AgEuPS4 (Ama2) can be successfully synthesized via the flux-assisted metal oxide–boron–chalcogen ...

来源：ACS PublicationsTwo-dimensional field-effect transistors (2D FETs) are promising candidates for next-generation semiconductor technologies, yet their adoption has been limited by the absence of gate dielectrics that simultaneously possess high dielectric constant (κ) and atomically smooth surfaces. Here, we present a heterohalogen polarization engineering strategy to boost the dielectric constants of LaOCl, LaOBr, PrOCl, PrOBr, NdOCl, and NdOBr by markedly improving the ionic and electronic polarizations. For example, F-polarized monolayer LaOCl (0.8 nm) achieves a record-high κ of 36.4 (a ...

来源：ACS PublicationsTransition-metal selenides have been widely investigated as promising candidates for energy-storage electrodes, benefiting from their intrinsic electronic transport capability and considerable theoretical charge-storage capacity. Despite their advantages, the practical utilization of these materials remains challenging because of sluggish kinetics and poor cycling durability. To overcome these challenges, this study introduced rare-earth Ce into (Ni,Co)Se2 and successfully synthesized Ce-doped (Ni,Co)Se2 nanomaterials. The incorporation of Ce refined the microstructure, resu...
