Summary: ZnS/ZnO nanocomposites were fabricated by a simple coating method, exhibiting higher photocatalytic activity due to the separation and transfer of photoexcited carriers at the contact. Additionally, thermal pre-treatment on ZnO thin films improved crystallinity and enhanced photocatalysis by extending the lifetime of the photoexcited carriers.

Summary: In this study, different types of ZnO-based nanocomposites were fabricated and characterized. The etching of ZnO nanorods increased the surface area and defect concentration, while sulfurization of the ZnO/ZnS nanotubes reduced defects and improved surface roughness. The results indicate that ZnO and ZnO/ZnS nanotubes hold promise for sensing device applications.

Summary: The physicochemical properties of three different ZnO tetrapodal nanostructures (ZnO-Ts) synthesized by a combustion process were studied and evaluated for label-free biosensing purposes. The chemical reactivity of ZnO-Ts was explored by quantifying the available functional hydroxyl groups (-OH) on the transducer surface necessary for biosensor development. The best ZnO-T sample was chemically modified and bioconjugated with biotin as a model bioprobe, confirming their suitability for biosensing applications through streptavidin target detection experiments.

Summary: Efficient preparation techniques of zinc sulfide (ZnS) nanostructured films using chemical bath deposition (CBD) have gained significant attention for optoelectronic applications. Parameters like deposition time, pH, precursor concentration, and temperature were found to influence the morphology and energy bandgap (Eg) of the films. The results demonstrated a correlation between deposition parameters and transmission, as well as Eg values, highlighting the potential for tuning these properties for optoelectronic applications.

Summary: The first synthesis of AgBr decorated ZnO/ZnS heterostructure was reported for powerful photocatalytic and antibacterial purposes. The addition of AgBr increased the specific surface area and decreased the optical energy gap of the ZnO/ZnS matrix. The nanocomposites exhibited enhanced photocatalytic efficiency and antibacterial activity due to the formation of various reactive species on the surface.

Summary: Constructing heterojunction ZnO/ZnS nanoarrays through hydrothermal method leads to enhanced piezo-photocatalytic performance compared to pure ZnO, with the degradation rate further improved by increasing ultrasonic power. The synergistic effect of piezoelectric effect and heterojunction photocatalysis plays a key role in this enhancement.

Summary: We successfully enhance the dielectric breakdown strength and electrostatic energy storage density of polymer-based materials by introducing heterostructure nanoparticles into the matrix. The special electrical rectification effect of these nanoparticles captures and confines charge carriers, resulting in suppressed leakage current and increased dielectric displacement and charge-discharge efficiency. The introduced heterojunction of ZnO-ZnS nanoparticles enables high energy storage performance, even at high temperatures and over long cycles.

Summary: This study presents a strategy for constructing hierarchically structured photocatalysts for efficient degradation of VOCs. By assembling nanobiochar, ZnO, and silver nanoparticles, VOCs can be quickly captured and dynamically diffused, and the charge transfer bridge built by the silver nanoparticles enables spatial separation of charge carriers and visible-light response. The photocatalyst exhibits high efficiency, universality, and stability.
