来源：ACS PublicationsControlling chemical homogeneity during aqueous coprecipitation of oxide nanoparticles remains challenging due to unintended byproducts that impact the microstructure and functionality of the final materials. Hence, precise tuning of structural, optical, and catalytical properties requires not only accurate knowledge of how such impurities evolve under annealing, but also effective strategies for defect engineering. Here, we demonstrate how hydroxylation and carbonation affect the internal structure and optical properties of YVO4 nanoparticles synthesized using different van...

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 ...
