Summary: This study applied a piezo-potential to ZnO/ZnS/MoS2 heterostructures to enhance the separation of photoexcited electrons and holes, resulting in increased production of H2. The heterostructures were synthesized through hydrothermal synthesis, and the H2 production varied with the different mixing ratios of ZnO and MoS2. When a piezopotential was introduced through ultrasonication during the photocatalytic reaction, the rate of H2 production significantly increased due to band tilting and improved charge transfer.

Summary: The core-shell structure with ZnO cores effectively suppresses surface defects, particularly in ZnO synthesized in an OH- rich environment, where the TiO2 shell coating has a stronger passivation effect on the surface defects. Both PL and XPS results confirm the effectiveness of the TiO2 shell coating in passivating surface defects of ZnO nanostructures.

Summary: The separation of photogenerated carriers is crucial for improving the efficiency of photocatalysis. This study proposes pine needle-like BaTiO3/ZnO continuous nanofibers with numerous interfaces, which have both photocatalytic and piezoelectric properties. Under ultrasonic waves, the piezoelectric potential generated by BaTiO3 and ZnO alternately breaks the shielding and efficiently separates photogenerated carriers, leading to an increased reaction rate constant compared to photocatalysis alone. This work provides a practical application significance in the field of water treatment.

Summary: ZnO nanostructures can emit strong UV near band edge (NBE) emission, and the UV emission efficiency can be enhanced by surface decorating with semiconductors or metals. The influence of metal coatings on the emission properties of ZnO nanorod arrays is studied, and it is found that the enhancement or reduction in the UV emission depends on the type of contact formed at the metal/ZnO interface, whether it is an ohmic or Schottky contact.

Summary: This study designed a high-performance self-powered photoelectrochemical sensing platform by integrating piezoelectric effect with localized surface plasmon resonance (LSPR) effect based on ZnO-WO3-x heterostructures. The combination of fluid eddy-induced piezoelectric effect and defect engineered WO3-x led to significant enhancements in photocurrent and maximum power output. After immobilizing the enrofloxacin (ENR) aptamer, the self-powered sensor showed excellent linearity and a low detection limit. This work holds great promise for high-performance self-powered sensing platforms in food safety and environmental monitoring.

Summary: ZnO flower-like (ZFL) and needle (ZLN) structures were synthesized and embedded into UV-curable acrylic resin (EB) to study their effect on the piezoelectric properties of the resulting composite films. The composites showed uniform dispersion of fillers within the polymer matrix. Increasing filler loading caused an increase in glass transition temperature and a decrease in storage modulus in the glassy state.

Summary: In this study, a vertical microcavity and localized surface plasmon resonance hybrid biosensor was proposed for high-throughput detection of SARS-CoV-2. The simulation and experimental results showed that nanoporous gold (NPG) deposited sensors performed better in resonance quality and sensitivity compared to gold-deposited and pure microcavity sensors. The pre-clinical validation demonstrated that 40% porosity NPG sensors had the highest sensitivity for SARS-CoV-2 pseudovirus in artificial saliva. The proposed automatic biosensing system showed potential for on-site coronavirus detection with sufficient sensitivity by delivering results of 100 samples within 30 minutes.
