Summary: In this study, a phase transition controlled hydrogen sensor was successfully fabricated by depositing an amorphous tungsten trioxide layer on a phase-change vanadium dioxide film. The response time and sensitivity of the hydrogen sensor were greatly improved by increasing the working temperature above the transition temperature of vanadium dioxide. Theoretical calculations revealed that the charge transfer at the vanadium dioxide/amorphous tungsten trioxide interface became more pronounced in the metal state, improving the sensor performance. This study not only achieved a high-performance hydrogen sensor based on vanadium dioxide, but also provided clues for designing gas sensors with phase-change materials.

Summary: MoS2 nanochains were successfully prepared using a facile electrospinning and hydrothermal process. The morphology of MoS2 nanochains was evaluated using field emission scanning electron microscopy and high-resolution transmission electron microscopy. A slurry composed of MoS2 nanochains was coated on a silver electrode for ammonia detection, showing a detection range of 25-500 ppm. The MoS2 nanochains exhibited excellent sensing response, reproducibility, selectivity, and a detection limit of 720 ppb. The responsiveness of MoS2 nanochains to ammonia remained unchanged for 1 week.

Summary: This study presents a novel strategy for antibacterial treatment using nanomaterial-based photothermal therapy. By loading Au nanoparticles on Ti3C2Tx nanosheets, the researchers achieved efficient antibacterial efficacy through photothermal ablation and physical contact over a supported nanostructure. The synergistically enhanced photothermal conversion efficiency and stability of the Au@Ti3C2Tx heterostructure were attributed to the localized surface plasmonic resonance effect. This work demonstrates the effectiveness of incorporating transition metal carbides with plasmonic metal nanostructures to enhance photothermal antibacterial efficacy.

Summary: In this work, hexagonal In2O3 nanosheets with decorated Au nanoparticles were synthesized and used as a sensor for NH3 detection. The sensor exhibited high response and fast response/recovery time at room temperature, as well as good repeatability stability and high selectivity. The excellent sensing behavior was attributed to the synergistic effect of nanosheets structure, Au nanoparticles-enhanced surface chemisorption, and the Schottky barrier. These synthesized hexagonal Au-In2O3 nanosheets provide a new candidate for exclusive NH3 detection at room temperature.
