Summary: In this study, gallium-doped zinc oxide nanowire arrays with different gallium doping concentrations were grown on glass substrates using a hydrothermal technique. The crystalline structure, morphology, and ultraviolet sensing performance of the samples were investigated. The results showed that well-aligned nanowire arrays could be achieved with gallium doping concentrations below 4%. Additionally, ultraviolet photodetectors prepared using the nanowire arrays exhibited excellent responses to 365 nm light.

Summary: The m-(Ni@SiC)(p) composite particles were prepared by modifying industrial coarse-grained SiC particles through a simple and environmentally friendly method. Surprisingly, the stored (Ni@SiC)(p) particles exhibited superhydrophobic properties with a contact angle of 156 degrees. This was attributed to the formation of a unique micro/nano hierarchical rough surface with some Ni oxidizing to NiO during long-term storage, resembling the microstructure of a natural lotus leaf.

Summary: Inspired by the lotus leaf surface, a magnetic sponge with robust superhydrophobicity and surface protection was synthesized. It provides a hydrophobic surface layer and builds rough surfaces at multiple scales, allowing for continuous and efficient oil-water separation. The sponge also offers protection and cross-linking, resisting damage and erosion caused by oil. Additionally, a conceptual diagram of a portable oil suction device was proposed, bringing potential ideas for the design of a portable vacuum cleaner-like oil-water separation device.

Summary: Nitrogen-doped ZnO nanorods with a lotus-leaf shape show enhanced CO2RR performance, with a maximum CO faradaic efficiency of 76% and durable activity exceeding 30 hours. Density functional calculations reveal that nitrogen doping reduces the free-energy barrier for key intermediate formation and enhances electron exchange, leading to notable improvement in CO2RR activity.

Summary: Metal oxide nanostructures with high surface-to-volume ratios are ideal for gas sensor fabrication. By depositing ZnO thin films on vertically aligned silicon nanowires with varying etching times, sensitivity and specific reactive surface of CO2 sensors can be improved. The sensors show low response and recovery times compared to those reported in literature.

Summary: In this study, a composite material of micro/nanostructured carbonized lotus leaf/ZnO/Au (C-LL/ZnO/Au) was obtained by treating fresh lotus leaf with Zn2+ followed by sintering and modification with gold nanoparticles. C-LL/ZnO/Au showed great mechanical bactericidal performance and photocatalytic sterilization. The antibacterial rate of mechanical sterilization for C-LL/ZnO/Au was 79.5% in 30 min, 4.7 times of fresh lotus leaf's figure under the same conditions. The introduction of gold nanoparticles in C-LL/ZnO/Au improved photocatalytic sterilization compared to carbonized lotus leaf/ZnO (C-LL/ZnO). The approach presented in this study has promising application potential in biomedical and public health fields.

Summary: Research in plasma actuation is focusing on enhancing thrust density for aerodynamic flow control. A new method involving nanoscaled structures and voltage/frequency tuning has been proposed and experimentally evaluated. Results show a 78% increase in thrust with nanostructures, but a threshold effect with lower voltages and frequencies impacting thrust generation. Electric characteristics are not sensitive to nanostructures, demonstrating the effectiveness of incorporating nanoscaled structures into DBD plasma actuators to improve mechanical performance.

Summary: A simple and reproducible method for producing high-quality zinc oxide nanorods (ZnO-NRs) was investigated. The growth process of hexagonal ZnO-NRs with c-axis orientation was optimized to study their optoelectronic properties. The results show that the growth temperature controls the surface density of ZnO-NRs, while the length is less affected. The ZnO-NRs exhibit high photosensitivity and have potential applications in optoelectronics and UV photo-detectors.

Summary: The optical properties of aligned nickel nanowire arrays with different degrees of oxidation were studied for terahertz polarizer applications using THz time-domain spectroscopy. It was found that increasing oxidation levels broadened the transmitted peaks in the frequency-domain spectra and caused a blue shift in peak positions, while also enhancing peak intensity. The transmittance of the arrays increased with annealing temperature, but the degree of polarization and extinction ratio decreased. The study also revealed a correlation between the degree of oxidation and the change in extinction ratio.
