Summary: Functional metal oxide particles, such as ZnO, are often added to polymers to create flexible polymer composites with good mechanical properties. In this study, ZnO microrods were prepared in the presence of cellulose nanofibrils (CNF), resulting in a layered composite structure. The stress transfer and mechanical properties of the composite were investigated using digital image correction and computational homogenization methods. The in-situ preparation of ZnO microrods led to a homogeneous distribution in the CNF matrix, unlike other methods that require external means like ultrasonication. The composites also showed potential for use as physiological motion sensors for human health monitoring.

Summary: Zinc oxide materials doped with varying carbon contents were successfully synthesized, resulting in ZnO samples with a hexagonal wurtzite structure. The crystallite size increased as the carbon doping increased. The sample size was approximately 400-500 nm, and the doped samples exhibited carbon microsphere adhesion. Furthermore, the optical band gap value decreased from 3.16 to 2.79 eV with increasing carbon doping, indicating a decreasing trend. Raman spectroscopy revealed that increased carbon doping led to a decrease in crystal quality and oxygen vacancy concentration. Photoluminescence spectroscopy showed that all ZnO samples contained oxygen vacancy defects and deep-level double ionized oxygen vacancies. The carbon-doped samples exhibited an increase in the proportion of interstitial zinc (Zn-i) defects and a decrease in the O-Zn concentration of substitutional defects.

Summary: In this study, Cu-doped ZnO nanoparticles were synthesized and investigated to explore the mechanism of room-temperature ferromagnetism in these dilute magnetic semiconductors. The results showed that the 2% Cu-doped sample exhibited the highest oxygen vacancies and saturation magnetization. UV spectroscopy indicated a reduced band gap upon Cu doping. Photoluminescence spectroscopy and XPS results revealed the presence of defect-related states associated with Cu doping. The induced magnetization in the Cu-doped nano-crystalline samples was proposed to be caused by the exchange interactions between Cu2+ ions and oxygen vacancies.

Summary: This paper demonstrates the synthesis of rhombic ZnO microrods surrounded by ZnO nanorods on zinc foils using a hydrothermal method. Photocatalytic degradation of Rhodamine B solution was employed to evaluate the photocatalytic performance of the fabricated samples. The hierarchical micro/nanostructures formed by ZnO nanorods surrounding the surfaces of rhombic ZnO microrods exhibited superior photocatalytic performance compared to rhombic Zn(OH)F and ZnO microrods. The enhanced performance can be attributed to the larger surface area of the hierarchical ZnO micro/nanostructures. Additionally, the ZnO nanorods grown on the rhombic ZnO microrods demonstrated recyclability and relatively stable photocatalytic performance.

Summary: The impact of oxygen concentration on the structural, optical properties, and device performance of Ga2O3 thin film was investigated by controlling the oxygen flow rate during deposition. Higher oxygen flow rate led to poorer crystalline quality, increased film roughness, and introduction of defects. Decreasing oxygen concentration resulted in an increase in optical bandgap, a decrease in blue band contribution, and reduced defect concentration, surface roughness, and interface states. These findings are significant for improving the quality of Ga2O3 films and their applications in device fabrication.

Summary: ZnO nanomaterials have been widely used for gas sensors due to their structural flexibility, earth abundance, and environmental friendliness. This study found that ZnO nanorods with a high amount of doubly positively charged oxygen vacancies showed superior gas sensitivity towards xylene, while Ga doping reduced the number of these vacancies and resulted in worse sensing performance. Therefore, doubly positively charged oxygen vacancies play a crucial role in the gas sensing performance of metal-oxide semiconductors.

Summary: In this study, all-inorganic lead-free halide perovskites Cs2SnX6 (X = Cl, Br, I) were synthesized using a simple room-temperature precipitation method. Material characterization revealed the presence of halogen vacancies, which contribute to their sensing capabilities. As room-temperature formaldehyde (HCHO) sensing materials, Cs2SnX6 showed varying sensitivities, with Cs2SnI6 exhibiting excellent selectivity, high response, short response/recovery time, good repeatability, and long-term stability. The sensing mechanism for HCHO was investigated, and it was found that the rich iodine vacancies on the Cs2SnI6 surface facilitated the oxidation of HCHO molecules. This work provides a promising candidate for practical HCHO detection at room temperature and offers insights for designing halide perovskites for future sensory devices.

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.
