Summary: In this study, the structural defects and thermal conductivity of CuO, ZnO, and CuO/ZnO nanowires were investigated using molecular dynamics simulation. The results showed the appearance of defects after simulation, with the formation of grains to reduce energy. The CuO nanowires exhibited a contraction effect on the basal plane, while the ZnO nanowires exhibited a contraction effect on the Zn-Zn distance and the length of the nanowires.

Summary: In this study, various ZnO nanostructures were synthesized using sol-gel technique with different solution pH values. The pH values were adjusted by adding NaOH solution dropwise, leading to different morphologies of ZnO nanostructures. The morphological structures were investigated using scanning electron microscope, and the structural and chemical analysis as well as optical characterizations were carried out using X-ray diffraction, FTIR, Raman and UV-vis spectroscopic techniques. The results showed that the ZnO nanostructures exhibited different shapes and crystallinity as the pH values varied. The optical properties of the ZnO nanocrystals were also found to be desirable. Raman and FTIR spectroscopy were used to further analyze the elemental and compositional characteristics.

Summary: The morphological properties of ZnO nanostructures such as nanorods, nanowires, and nanotubes can significantly affect their photocatalytic performance. In this study, the physical properties (optical and shape) of different 1-D ZnO nanostructures were evaluated in relation to their photocatalytic efficiency. ZnO nanorods transformed into nanowires under reduced seeding precursor concentration and into nanotubes with prolonged incubation time. The highest photocatalytic efficiency was observed in ZnO nanotubes, followed by ZnO nanowires and nanorods. The enhanced efficiency of ZnO nanotubes was attributed to their large polar face, high UV absorption, and large photocurrent density.

Summary: The performance of a photodetector consisting of micropyramid structured p-Si/n-ZnO NWs heterojunction is optimized using the pyro-phototronic effect, leading to a significant increase in photoresponsivity. Furthermore, the introduction of chopper frequency and a thin film Al layer as the back electrode further improve the photocurrent and photoresponsivity. The coupling between the pyrophototronic effect and the piezo-phototronic effect is analyzed, showing a decrease in photoresponsivity and photocurrent under compressive strain.

Summary: The properties of Au/ZnO materials with different Au contents were studied, and it was found that the presence of Au led to pronounced plasmon resonance and faster decay rate. The effect of Au particles on the radiative recombination rates of ZnO was quantified by fitting and integrating the coverage of Au atoms on the surface. The highest charge trapping efficiency of Au atoms was observed at very low coverage.

Summary: ZnO/xPt nanocomposites obtained by the solvothermal method were used for microextrusion printing of films onto special Al2O3/Pt sensors. The samples showed temperature and frequency dependence of conductivity. The highest response was observed at 225 degrees C for ethanol. By increasing platinum content, the response to ethanol increased but the process kinetics deteriorated. The sensors can be used for the selective separation of a wide range of gases.
