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: Mixed transition metal oxides are promising electrode materials for electrochemical energy storage and conversion. The synthesis of these materials with tailored composition, crystal structure, and morphology is crucial for optimizing their properties. This study reports on the room-temperature electrodeposition of a ternary oxide, ZnMnO3, using earth-abundant metals. The epitaxial growth of ZnMnO3 on ZnO nanowires results in a 2-dimensional morphology and shows promise for the direct growth of other mixed transition metal oxides on conductive substrates.

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 degradation of rose bengal dye was studied under UV irradiation using CeO2 doped with oxygen-deficient Gd3+ ions prepared via the sol-gel technique. XRD analysis confirmed a single-phase crystalline structure with crystallite size ranging from 7.38 nm to 9.48 nm and lattice parameters ranging from 5.407 angstrom - 5.420 angstrom. HR-TEM analysis revealed spherical particles with sizes in the range of 7.6 nm-9.8 nm. Raman analysis confirmed the presence of oxygen vacancies. The synthesized photocatalysts exhibited excellent degradation performance for rose bengal dye under UV irradiation, with degradation rates increasing from 73.06% to 92.32% upon doping, and thus have potential applications in environmental remediation.

Summary: This study compared two methods, adsorption and in situ incorporation, for preparing hybrid polyphenol/hydroxyapatite nanoparticles. The results showed that adsorption of polyphenols on pre-formed nanoparticles did not change their properties, while in situ incorporation inhibited hydroxyapatite formation but resulted in higher loadings. Most hybrid particles exhibited a burst effect followed by slow release over time.

Summary: This work developed a simple and time-dependent method to synthesize CuO nanoribbons. The concentration of precursor salt, surfactant, and reaction time were varied to determine the synthesis conditions. The morphology, chemical composition, and structure of CuO nanoribbons were characterized using SEM, TEM, XRD, and EDS. The study found that the amount of PVP greatly influenced the morphology of the nanostructures, with low amounts promoting the formation of nanoribbons and larger amounts stabilizing the formation of octahedral particles.

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.
