Summary: The present study demonstrates the novel and promising application of zero valent metallic selenium (Se) in photocatalysis under visible light. Se was dispersed into a polyvinyl chloride (PVC) and polyvinylidene fluoride (PVDF) polymeric solution (Se-PVC/Se-PVDF matrix) using a reflux-calcination method. The results showed that Se nanoparticles were well dispersed and mixed in the polymer solution, leading to enhanced generation of photoinduced electrons and reduced transfer resistance. Photocatalytic activity was further studied using potassium iodide (KI) and isopropyl alcohol (IPA), and the order of photocatalytic activity decrease was determined.

Summary: In this study, MoSe2 nanoflowers (NFs) were utilized as piezoelectric nanozymes for the dual-driven catalytic eradication of multi-drug-resistant bacterial biofilms. The piezoelectricity of MoSe2 NFs, combined with their enzyme-mimic activity, led to a significant increase in oxidative stress in the biofilms under ultrasound irradiation, resulting in a 4.0 log10 reduction of bacterial cells. In vivo studies showed that the MoSe2 NFs effectively reduced the burden of methicillin-resistant Staphylococcus aureus in mice under ultrasound control. Additionally, the surface coating of antioxidant poly(ethyleneimine) minimized off-target damage and promoted wound healing.

Summary: This study proposes a high-performance flexible piezoelectric sensor (HFPS) based on a novel zinc oxide/polyacrylonitrile/Ecoflex composite membrane. The HFPS exhibits increased output voltage/current compared to the pure ZnO/Ecoflex composite membrane due to the synergistic piezoelectricity of ZnO and PAN. Additionally, the fabricated HFPSs demonstrate excellent sensitivity, linearity, stability, and flexibility under periodic pressure. Based on its flexibility, stretchability, and battery-free characteristics, a self-powered HFPS-based intelligent glove is proposed for wireless control of various electronic systems through human hand gestures. The glove has been successfully applied to car two-dimensional motion, light bulb control, and fan control, offering new application prospects for human-machine interaction systems with its advantages of simple operation, portability, and low power consumption.
