Abstract

The efficient detection of n-butanol, which is in demand for highly sensitive materials, is essential for multiple applications. A nonaqueous method was applied to prepare NiFe2O4 nanoparticles (NPs) using benzyl alcohol as a solvent, which shows a size of 7.9 ± 1.6 nm and a large surface area of 82.23 m2/g. To further improve the sensing performance for n-butanol, Pd/PdO functionalization was sensitized with NiFe2O4 NPs. Gas sensing results demonstrate that the Pd/PdO-NiFe2O4 exhibits an enhanced response of 36.9 to 300 ppm n-butanol and a fast response and recovery time (18.2/17.6 s) at 260 °C. Furthermore, the Pd/PdO-NiFe2O4-based sensor possesses a good linear relationship between responses and the n-butanol concentration from 1 to 1000 ppm, and great selectivity against other volatile organic compounds (VOCs). The excellent sensing enhancement is attributed to the catalytic effects of Pd/PdO, the increase of oxygen vacancies, and the formation of heterojunction between PdO and NiFe2O4. Thus, this study offers an effective route for the synthesis of Pd/PdO-functionalized NiFe2O4 NPs to achieve n-butanol detection with excellent sensing performance. [ABSTRACT FROM AUTHOR]

33. Effect of MoS2on microstructure and mechanical property of ultrasonically welded carbon fiber/polyamide 66

Abstract

Porous defect induced by thermal decomposition is one of the most significant factors in determining the weld quality of ultrasonically welded thermoplastics. MoS2has high thermal stability and a two-dimensional layer structure, which could play a key role in improving the thermal stability of the thermoplastics. In this study, MoS2with 0.5 wt%, 1.0 wt%, 1.5 wt%, and 2.0 wt% loadings are incorporated into carbon fiber/polyamide 66 composite (CF/PA 66), and its effect on microstructure and mechanical properties of the joint is evaluated with the combination of finite element analysis. Results showed the incorporation of MoS2slightly influenced tensile property of the composite while had a considerable effect on joint performance. With 1.5 wt% loading of MoS2, the highest peak load was enhanced to 6.20 kN from 5.05 kN and the difference in peak load became limited. This is mainly because the temperature of the workpiece under the horn rose above the thermal decomposition point of the composite during ultrasonic welding (UW). However, MoS2filler improved the thermal stability of the workpiece and alleviated the thermal decomposition of PA 66 during UW. As a result, the workpiece with MoS2addition can endure longer weld time to increase the weld area of the joint and improve the weld microstructure and porous defect, which results in higher peak load and stability. This work provides a new solution for improving the joint strength of ultrasonically welded thermoplastics.
