Interface Reconstruction Induced by Rare-Earth Incorporation Stabilizes High-Coordination Cu+ Sites for Efficient Electrochemical Nitrate Reduction to Ammonia 来源：ACS PublicationsThe electrochemical nitrate reduction reaction (eNO3–RR) represents a promising route for simultaneous wastewater treatment and sustainable ammonia synthesis. While Cu2O catalysts featuring electron-deficient Cu+ sites have been widely studied for eNO3–RR, their practical implementation is hindered by self-reduction and structural instability. Constructing Cu–O–M interfacial sites, which enhance charge transfer and sta...

Hybrid Solvation Model for Analyzing the Binding of Yttrium and Calcium Cations to the Lanmodulin Protein Using the Fragment Molecular Orbital Method 来源：ACS PublicationsA hybrid solvation model combining microsolvation with continuum solvent is proposed to analyze the binding of calcium and yttrium cations to the lanmodulin protein (PDB: 6MI5), using the fragment molecular orbital method combined with partition analysis. The contributions of protein deformation, metal ion desolvation, and the formation of a water cluster from desolvated metal ions, as well as protein–ion and water-ion interact...

来源：ACS PublicationsChemically flexible A2B2O7 oxides are attractive candidates for designing structure-specific functional materials by judicious substitution. However, modulating functionality by substitution is governed by the solubility limits of the substituent. Present work reports an a typical 10 mol % solubility of Y3+ in La2Ti2O7(LTO:10Y), substantially lower than 60 mol %, anticipated by cationic radius ratio guidelines (rA/rB) for A2B2O7. Systematic experimental and theoretical investigations have been performed to justify this limited solubility. The solubility of Y3+ in La2Ti2O7 wa...

来源：ACS PublicationsRational design of Eu2+-activated red phosphors under visible light excitation remains a critical challenge in various fields such as photonics, optoelectronics, and white-light-emitting diodes. Herein, we engineer high density traps with a double metastable state in the SrZnOS matrix by constructing the reversible infinitesimal photoelectrochemical layered micro-unit battery structure via co-doping Eu2+ and Dy3+ ions for achieving robust red luminescence. The resulting SrZnOS:Eu2+,Dy3+ phosphor exhibits intense red photoluminescence at 620 nm under 468 nm excitation, matchi...
