Summary: Metal-oxide gas sensors, particularly the SnO2-CuO system, are widely used for detecting H2S gas. While the previous 2D thin bilayer model explained some aspects of the sensor's performance, experimental research showed that multicomponent heterostructures have higher response. By introducing an n-p-n junction in a 3D model, the sensitivity of the sensor element towards H2S gas significantly improved, indicating the potential for optimized sensor fabrication.

Summary: In this work, intrinsic and p-type ZnO nanowires were successfully synthesized and used to fabricate strain sensors and homogenous p-n junction ZnO devices. The nanowires were grown using different methods and exhibited good rectification characteristics, but electroluminescence was difficult to achieve due to low carrier concentration in the ZnO single crystal.

Summary: The photocatalytic activity of p-Si/p-CuO buffer layer/n-ZnO nanorod composite films was studied using experimental and simulation methods. The simulation results showed that the 250 nm CuO buffer layer contributed the highest percentage (11%) to the total current density compared to p-Si/n-ZnO composite films. The experimental results also indicated that by introducing the p-CuO buffer layer, the pseudo-order rate constant (k) could be enhanced by 12%, and the composite film exhibited high photostability.

Summary: Establishing a platform with different nanostructured oxides is a novel idea for developing highly sensitive and selective sensing devices. The study successfully created 3D-heterostructures consisting of 1D nanowires of NiO and WO3, exhibiting selective behavior towards different gases. The improved sensing performance of the heterostructures is attributed to charge carrier transport through specific interfaces and modulation of charge carriers in the electron depletion layer of WO3 and hole accumulation layer of NiO and NiWO4.

Summary: N atoms were successfully doped into the lattice of ZnO nanoparticles using ZIF-8 as a self-sacrificial template through a thermal treatment process with the assistant of urea. The obtained N-ZnO exhibited competitive ethanol-sensing performance. It was found that N-doping facilitated the formation of oxygen vacancy and the larger specific surface area resulting from size reduction during the urea-assisted pyrolysis process contributed to the improved ethanol-sensing performance.

Summary: The study proposes an inverse design by depositing n-type ZnO shell layers on the surface of p-type CuO core-shell nanowires to understand their conductometric gas-sensing kinetics. The surface morphologies of bare and core-shell nanowires were investigated using FE-SEM. The ZnO shell layer was observed using EDX and HRTEM techniques.

Summary: Nanostructure modulation is effective for high performance TiO2-based gas sensors. By using a wet-chemistry route to precipitate directly branched TiO2 nanowire arrays on alumina tubes, the sensors exhibit enhanced response due to the unique porous architecture and quasi-aligned nanostructure. The phase junctions between the backbone and branch of the branched TiO2 nanowire arrays help resistance modulation, leading to excellent sensor properties.

Summary: CuO-ZnO heterostructures containing different concentrations of Zn were synthesized via hydrothermal synthesis and used for xylene vapor detection. The sensor showed excellent selectivity, stability, and sensitivity towards xylene vapor, with a low detection limit of 9.5 ppb and a sensitivity of 0.063 ppm-1. The superior gas sensing characteristics of the CuO-ZnO heterostructure can be attributed to its large surface area, the creation of a p-n heterojunction, and the strong chemical affinity and catalytic performance of p-type CuO towards xylene vapor. The response mechanism to xylene was also clarified.

Summary: A novel ternary BiOCl/TiO2/clinoptilolite (BTC) nanocomposite with highly-enhanced photocatalytic activity under visible light was successfully prepared via a facile hydrothermal route, showing excellent adsorption and degradation performance for the target contaminant SIPX. The enhanced photocatalytic activity was mainly attributed to the effective construction of the BiOCl/TiO2 heterojunction and the excellent adsorption ability of the clinoptilolite in the BTC nanocomposites, as confirmed by characterization analysis and experimental results. Radical scavenger tests indicated that superoxide radical anions and photogenerated holes were the dominant active species in the reaction system, suggesting the potential of these novel nanocomposites as efficient photocatalysts for complete degradation of xanthates under visible light.

Summary: Chemiresistive CO2 sensing using well-developed ZnO material with nitrogen doping has been studied. It was found that the response to CO2 is higher in the presence of nitrogen doping and under N2 background. Density functional theory calculations revealed that nitrogen doping is responsible for the observed response. In the presence of pre-adsorbed O2, the interaction between N-doped ZnO and CO2 is hindered, resulting in limited response in air.

This study investigated the adsorption characteristics of commonly tested gases on different facets of ZnO using a DFT method. The results showed that each facet exhibited different levels of selectivity towards different gases, and the selective adsorption was attributed to a combination of electronic structure matching and geometric matching.

Summary: This paper analyzes the influence of the feed body structure on the internal flow field and particle distribution characteristics of the Axial Velocity Wave Zone (AVWZ) in a hydrocyclone. The results show that the structural parameters of the inlet structure have a complex effect on the separation performance, which is reflected in the characteristics of the AVWZ. Changes in the inlet diameter affect the flow field, centrifugal strength, turbulence strength, and particle distribution, while the inlet aspect ratio is mainly influenced by the settling distance of particles. The AVWZ provides a basis for designing the inlet structure to improve separation performance.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
