来源：ACS PublicationsFor next-generation applications, recent developments in sensor fabrication technologies and innovative materials have rendered improved temporal response and spectral detection capabilities feasible. This work demonstrates a dual-mode sensor for simultaneous light and temperature detection. Vacuum thermal evaporation was used to deposit nanostructured polycrystalline TeO2–Li2O–ZnO–Nb2O5–Dy2O3 (TLZND) thin films (∼32 nm crystallites) on monolithic substrates. Field-emission scanning electron microscopy revealed surface morphology and roughness, while Fourier transform infrar...

来源：ACS PublicationsRare-earth oxide-supported Ru metal catalysts are promising for NH3 synthesis owing to a strong metal–support interaction. Modifying rare-earth oxides with a second metal offers an effective approach to tuning support properties, while systematic support engineering to enhance NH3 synthesis performance remains scarce. In this work, a series of Ru/Ce1–aLaaOx catalysts with varying Ce-to-La molar ratios were synthesized and evaluated for NH3 synthesis. The NH3 synthesis rate of Ru/Ce1–aLaaOx exhibits a volcano relationship with an increase in the La content. The optimal Ru/Ce0...

来源：ACS PublicationsLanthanum is widely used as a structural and textural promoter in zeolite-containing FCC catalysts. This work investigates the structural, textural, and sorption properties of the solid residue formed after acid leaching of lanthanum from spent petroleum hydrocarbon cracking catalyst. It is shown that nitric and sulfuric acids treatment aimed at extracting the rare earth element leads to significant changes in the chemical composition and surface characteristics of the residual material, while the crystalline Y-type zeolite framework is preserved. The aluminum content in the...

来源：ACS PublicationsThis study reports the synthesis of two rare-earth imidonitridophosphates and a series of 3d transition metal imidonitridophosphates (MIIIH3P6N12 with M = V, Cr, Eu, Lu, and MIIH4P6N12 with M = Mn, Fe, Co, Ni) by high-pressure metathesis. The crystal structures were elucidated by a combination of single-crystal and powder X-ray diffraction, elemental analysis, and vibrational spectroscopy. All compounds crystallize in the orthorhombic crystal system (transition metal imidonitridophosphates: Cmce, EuH3P6N12: Pna21, LuH3P6N12: Pbam) and feature a layered anionic network compos...
