来源：X-MOLDifferent lanthanum manganite-based thin films were prepared by polymer assisted deposition (PAD) and spin coating on the monocrystal SrTiO3 (001) and Si substrates, whereas double-layered film was obtained by combining PAD and sol-gel method to deposit second perovskite Ba0.7Sr0.3TiO3 layer. Valence states of ions were probed by X-ray absorption spectroscopy (XAS) at the SOLARIS National Synchrotron Radiation Centre in Kraków, Poland. It was found that manganese valence depends on substrate type, doping level, and BSTO buffer layer which is important to obtain single-phase comple...

SHAP enhanced machine learning prediction of structure–property relationships in plasma sprayed lanthanum zirconate coatings for TBC applications 来源：X-MOLThe performance limitations of traditional yttria-stabilized zirconia (YSZ) have prompted the investigation of lanthanum zirconate (LZ) thermal barrier coatings (TBCs) as potential alternative topcoat materials. This study addresses the limitations of conventional statistical methods by introducing an innovative hybrid framework that integrates the Design of Experiments (DoE), Machine Learning (ML), and SHapley Additive exPlanations (SHAP) to...

来源：ACS PublicationsThe structural flexibility of BiVO4-based ceramics enables diverse electrical functionalities, ranging from oxide ion conductivity to promising dielectric performance. This study investigated the structural evolution, electrical transport, and dielectric behavior of Bi1–xLaxVO4 (0 ≤ x ≤ 1) ceramics, in which Bi3+ is progressively substituted by La3+. Using variable-temperature X–ray diffraction (VT–XRD) and neutron powder diffraction (NPD), the phase transitions and crystallographic parameters were systematically analyzed. La3+ substitution induces a structural transformatio...

Highly Selective Photocatalytic CO2-to-CH4 Conversion in Water Vapor via CeO2/Carbon Nitride Nanosheet Heterojunctions 来源：ACS PublicationsSolar-driven CO2 reforming in water vapor to produce high-value-added chemical fuels offers significant potential for renewable energy. Achieving this conversion under mild conditions can be efficiently realized through multielectron-coupled proton transfer (M-ECPT) photocatalysis. This work introduces CeO2/CNs-NKM, a composite synthesized by firmly anchoring highly dispersed cerium oxide (CeO2) onto crystalline carbon nitride nanosheets (CNs-NKM). Experime...
