Synergistic Adsorption-Catalysis by Co/Ce Dual Single Atoms Trapped in Hollow Carbon Spheres Boosts Li–S Battery Performance来源：ACS PublicationsLithium–sulfur (Li–S) batteries have a deteriorating capacity under the circumstances of the lithium polysulfide (LiPS) shuttle effect, which disrupts S8-to-Li2S conversion kinetics and shortens the cycle life. In this study, we engineered Co/Ce dual single atom catalysts anchored on nitrogen-doped hollow carbon spheres to mitigate the shuttle effect by adsorption-catalysis design. Ce sites exhibit stronger adsorption affinity for long-chain LiPS via th...

Yttrium-Doped Ru Nanoparticles Stabilized on Carbon Nanotubes as Bifunctional Catalysts for High-Efficiency Acidic Water Electrolysis来源：ACS PublicationsRuthenium, a promising lower-cost, high-activity alternative to iridium for acidic PEMWE oxygen evolution, requires innovative stabilization and bifunctionality enhancement strategies due to its dissolution and nanoparticle instability under OER conditions and inferior HER activity compared to platinum. Herein, a novel strategy for bifunctional acidic water electrolysis catalysts integrates Y-doped Ru nanoparticles onto CNT-decorated carbon clo...

Multifunctional Role of Eu3+ in NaSrBiTeO6 Double Perovskites for Solid-State Lighting, Temperature Sensing, and Latent Fingerprint Applications来源：ACS PublicationsStrong red-emitting cubic NaSrBiTeO6:Eu3+ double-perovskite phosphors with different Eu3+ concentrations were synthesized using a solid-state diffusion method at 850 °C. Rietveld refinement of the XRD patterns confirmed that the incorporation of Eu3+ did not modify the crystal structure framework. Characteristic vibrational modes were observed using FTIR and Raman spectroscopy, whereas SEM-EDX analysis revealed irregular microcr...

Structural, Optical, and UVA-Emitting Persistent Luminescence Features of Ba1–xAl2Si2O8:(x = 0–0.05)Eu2+ and Its Anticounterfeiting ApplicationResearch concerning UVA-emitting persistent luminescence (PerL) phosphors is growing due to their potential applications in phototherapy, sterilization, photocatalytic activity, etc. We report the structural and optical properties of undoped and Eu2+-doped BaAl2Si2O8 phosphors synthesized using the solution combustion method with varying Eu concentrations from 1 to 5 mol %. Structural analysis confirms that the undoped and Eu2+-doped samples crystallize...
