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: Considering the significant risk of H2S gas to human life, research on H2S gas sensors has gained considerable interest. This study presents the fabrication of CuO/ZnO multifaceted nanostructures through heat treatment of Cu2+/ZIF-8 impregnation precursors, and evaluates their microstructure and gas sensing characteristics using various characterization techniques. The hollow CuO/ZnO nanostructures demonstrated high gas response, quick response and recovery times, low detection limit, good humidity resistance, and high selectivity towards H2S gas, which can be attributed to their porous hollow nanostructures, p-CuO/n-ZnO heterojunctions, and the spillover effect between CuO and H2S.

Summary: In this study, we investigate the temperature limitations for the growth of copper oxide nanowires through thermal oxidation of copper, which has been a long-standing puzzle for scientists. By gradually lowering the oxidation temperature and using electron microscopy techniques, we determine the lowest temperature at which nanowire growth is observed and the smallest nanowire diameter achievable. Our experimental results are supported by theoretical modeling, providing insights into the nucleation processes of nanowires. The temperature dependence of the critical nucleus size governs the limiting diameter of the nanowires.

Summary: The study investigated charged oxygen-related species on three naturally occurring surfaces of SnO2 and found that upon adsorption of atmospheric oxygen, superoxide O2- and doubly ionized O2- can spontaneously form, with the latter being identified as the source of sensing response. The doubly ionized O2- species induces a large displacement of surface Sn, resembling the coordination of Sn2+ in SnO, which is necessary for stabilizing O2- and activating metal-oxide surfaces for gas sensing.

Summary: This study experimentally investigates the influence of magneto-water-wetting on CO2 adsorption in MgO/Mg(OH)(2) nanocomposites and reveals a phenomenon contrary to popular belief. Magneto-water-wetting does not always increase CO2 adsorption; it may actually decrease CO2 adsorption. Structural research suggests that the blocking effect of a thin H2O layer between nanograins can explain this phenomenon. Lastly, the magneto-water-wetting technique can control the carbon-hydration process and provide significant insights and discoveries for CO2 capture from air.

Summary: This study investigated the effect of the mixing ratio of TiO2 nanoparticles (P25) and titanium alkoxide (T-sol) on various properties of TiO2 films. The specific surface area, microstructure, thickness, transmittance, pencil hardness, and oil contact angle of the films were analyzed. The results showed that the specific surface area increased as the P25 content increased, but this effect decreased as the ratio of T-sol to P25 increased. The thickness, surface roughness, transmittance, pencil hardness, and oil contact angle of the films were also affected by the P25 content, with increased thickness and surface roughness, decreased transmittance and pencil hardness, and decreased oil contact angle.

Summary: The study of stress-strain nonlinear deformation is fundamental in various branches of science and engineering, yet the atomic processes that occur inside solids during mechanical loading are still unclear. This work presents new equations based on entropy changes on surface wetting to characterize the stress-strain nonlinear deformation. The derived equation is validated through measurements and modeling of water contact angles under different strain loadings in various materials. These findings may have important implications for non-destructive testing, featureless fluid navigation, and anti-biofouling research.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
