Summary: In this study, a vibration energy harvester based on a two-dimensional acoustic black hole (ABH) was proposed, which utilizes the wave energy focus effect of ABH to increase harvested power. The structure of ABH was designed and analyzed using numerical simulation, and optimal parameters such as power index, truncation thickness, cross-sectional length, and round table diameter were obtained. The quadratic velocity of the plate surface with ABH was determined to be 22.33 times higher than that of a flat plate, and PZT film was attached to the corresponding positions of the ABH structure and plate structure. Under the same excitation-vibration condition, the average output power of a PZT with an ABH structure was found to be higher than that of a flat plate.

Summary: Chirality arises from the asymmetry of materials, where two counterparts are the mirror image of each other. The interaction between circular-polarized light and quantum materials is enhanced in chiral space groups due to the structural chirality. Tellurium (Te) possesses the simplest chiral crystal structure, with Te atoms covalently bonded into a spiral atomic chain (left-or right-handed) with a periodicity of 3. Here, we investigate the tunable circular photoelectric responses in 2D Te field-effect transistors with different chirality, including the longitudinal circular photogalvanic effect induced by the radial spin texture (electron-spin polarization parallel to the electron momentum direction) and the circular photovoltaic effect induced by the chiral crystal structure (helical Te atomic chains). Our work demonstrates the controllable manipulation of the chirality degree of freedom in materials.

Summary: In this study, an atomically dispersed Fe-Pt dual-site catalyst (FePtNC) with high catalytic activity has been designed by modulating the electronic structure between adjacent metal sites. The FePtNC catalyst exhibited significantly better catalytic activity than single atom catalysts and metal-alloy nanocatalysts, with a half-wave potential of 0.90 V for the oxygen reduction reaction. Metal-air battery systems fabricated with the FePtNC catalyst showed peak power density values of 90.33 mW cm(-2) (Al-air) and 191.83 mW cm(-2) (Zn-air). The enhanced catalytic activity of the FePtNC catalyst is attributed to the electronic modulation effect between adjacent metal sites, which was demonstrated through experiments and theoretical simulations.
