Summary: The effects of La3+ and Al3+ substitution on the structural, dielectric, and piezo-electric properties of (1-x)(K0.5Bi0.5)TiO3-xLaAlO3 ceramics were investigated. With the increase in LAO content, a decrement in tetragonal distortion and an increase in cubic symmetry were observed. The incorporation of LAO in KBT resulted in an improved relaxor behavior and a suppression of oxygen vacancies. The piezo-electric properties were enhanced, with the 3% LAO-doped sample exhibiting the highest piezo-electric charge coefficient and improved piezo-electric voltage coefficient. An energy harvesting experiment was performed on the poled 3% LAO-doped ceramic, showing promising results under normal finger tapping.

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.
