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: 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.
