Summary: In this study, a series of Pr6O11 catalysts were developed by CTAB-assisted coprecipitation method and their catalytic performances for soot oxidation and NOx adsorption were investigated. The Pr6O11 catalysts exhibited excellent catalytic activities for both soot oxidation and NOx adsorption at low temperature, which was attributed to their relatively large surface area, strong NO oxidation ability, and high intrinsic activity. The presence of NO was found to promote the soot oxidation, and the possible mechanism of the soot oxidation reaction process was explored using in situ DRIFTS.

Summary: This paper demonstrates how the composition of bimetallic Fe-Ni exsolution can be controlled by the nature and concentration of oxygen vacancies in the parental matrix, and how this affects the performance of CO2-assisted ethane conversion. The use of mesoporous A-site deficient La0.4Sr0.6-alpha Ti0.6Fe0.35Ni0.05O3+/-delta perovskites enables fast exsolution kinetics of bimetallic Fe-Ni nanoparticles. The control of reduction and growth processes of bimetallic exsolution offers interesting prospects for the design of advanced catalysts based on bimodal nanoparticle heterostructures.

Summary: We predict and realize a new magnetic and semiconducting material, MnSnN2, through combinatorial sputtering of thin films. MnSnN2 exhibits a wide composition tolerance, with a single-phase region of 20% < Mn/(Mn + Sn) < 65%. The material shows a wurtzite-like crystal structure with cation disorder and has an optical absorption onset of 1 eV, consistent with the computationally predicted 1.2 eV bandgap. Resistivity and Hall effect measurements confirm the semiconducting nature of MnSnN2 and reveal complex charge transport mechanisms. Magnetic susceptibility measurements show a low-temperature magnetic ordering transition and strong antiferromagnetic correlations in MnSnN2, contrasting with previous studies on cation-ordered MnSiN2 and MnGeN2.

Summary: The novel La-B-O-C composites were fabricated as catalysts for methane catalytic combustion at low temperature. Three metal ions (Co, Mn, Fe) were selected for experiment based on the effect of the newly formed C-O bond on B-site ions as active sites. The study showed that different metal ions had varying effects on the physicochemical properties and catalytic performance of the composites, with LC-C and LF-C showing superior performance compared to unmodified catalysts, while LM-C showed a slight decrease in performance. Sacrifice of Mn4+ in LM-C was found to weaken the catalytic activity. Mechanistic differences for different B-site elements in the La-B-O-C were also observed.

Summary: In this study, high-entropy wolframite oxide (CoCuNiFeZn)(1-x)GaxWO(4) was synthesized through a solid-state route followed by spark plasma sintering, and their structural, microstructural, and thermoelectric properties were investigated. The results showed a monoclinic structure with a decreasing unit cell volume as the Ga content increased. The optical bandgap exhibited a cocktail effect in the high-entropy configuration. The dominant charge carriers were found to be electrons with a nondegenerate behavior based on the Seebeck coefficient. The electrical resistivity decreased with increasing temperature, indicating a semiconducting nature. The thermal conductivity of the high-entropy samples was significantly lower compared to MgWO4, which can be attributed to the strong phonon scattering caused by the large lattice disorder in the high-entropy configuration. Ga doping positively modified all three thermoelectric parameters, resulting in an increase in the thermoelectric figure of merit (zT).

Summary: It has been experimentally proven for the first time that nanoparticles deposited on the surface of a micropowder perform the role of relaxation centers for the primary defects induced by radiation. This study focuses on the radiation stability of ZnO powders modified with TiO2 nanoparticles. The results show that TiO2 powders act as a protective layer by absorbing part of the incident radiation. When exposed to radiation, primary defects are formed inside the micropowder, and the nanoparticles act as relaxation centers for these defects, reducing their concentration.

Summary: This study presents a silicon dielectric metamaterial (SDM) composed of two outer symmetric semi-circular rings and two inner symmetric split-ring resonators (SRRs). The electromagnetic responses of the SDM device in different modes were studied through numerical simulations and experiments. Increasing the structure height of the SDM device resulted in red-shifted resonances and stronger intensities. This study provides a new design strategy for the development of frequency filtering, polarization switching, and resonance modulation characteristics in THz-wave applications.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
