Summary: The introduction of catalyst on the anode of a solid oxide fuel cell is an effective method to alleviate carbon deposition when using biogas as fuel. La0.6Sr0.4Co1-xNixO3-delta oxides showed good performance as catalyst precursors for biogas dry reforming, inhibiting carbon deposition on the Ni-based anode through the formation of NiCo alloy active species after reduction in H2 atmosphere.

Summary: The superconducting properties and structural parameters of LaO0.5F0.5BiS2-xSex, a BiCh2-based layered superconductor (Ch: S, Se), were investigated. Increasing the Se concentration led to an increase in the superconducting transition temperature (Tc) and the induction of bulk superconductivity. A larger Gruneisen parameter (gamma G) was observed when x>=0.4, indicating improved superconducting properties. The study also found a positive correlation between gamma G and Tc in Se-poor samples of REO0.5F0.5BiS2 (RE = Pr, Nd). Additionally, specific heat analyses revealed the existence of a low-energy optical phonon mode in LaO0.5F0.5BiS2-xSex.

Summary: Understanding the charge transfer mechanism in the straddle heterojunction architecture is crucial for designing active materials. The synthesis and thorough study of BiVO4, La1-xSrxFeO3-delta perovskites, and BiVO4@La1-xSrxFeO3-delta straddle heterojunction architectures addressed this issue. The insertion of Sr2+ ions into A-sites increased the Fe4+ ions at B-sites, strengthening the Fe-O bond and improving electrocatalytic activity. The increased Fermi levels reduced band bending and enhanced the drift direction of photoinduced charges, leading to significantly higher photocurrent in the heterojunction architecture.

Summary: By adding non-equimolar ratio Cu element into Cr, Fe, Ni, Al, and Si pure powder, high entropy alloys (HEAs) were prepared with varying Cu content. The addition of Cu increased the fcc phase in the alloy, while maintaining a higher content of bcc phase. The CrFeNiAlSiCu0.4 alloy exhibited the best overall performance, with highest microhardness, lowest wear and corrosion current, and highest corrosion potential.

Summary: The LaCrO3 perovskite oxides doped with cobalt were synthesized using a combustion technique. Characterization confirmed the formation of a single perovskite-type structure and showed that the incorporation of cobalt led to structural changes and relevant surface properties. The conversion of CO and O-2 was influenced by the cobalt content and temperature, with stability tests indicating stable conversion rates for CO and O-2.

Summary: By systematically studying the physico-chemical properties of La1-xSrxCo0.8Fe0.2O3 catalysts, it was found that Sr doping improved the reducibility of Co and oxygen deficiencies, resulting in significantly increased NO conversion rates. This improvement in catalytic activity was attributed to a surface process determined by adsorbed NO and surface oxygen species.
