Summary: ZnO/Cu2S nanotube arrays were fabricated using a simple method without capping agents, and their photo-electrochemical performance was systematically studied. The enhanced performance of ZnO/Cu2S was attributed to improved visible light absorption, effective separation of photo-induced carriers, and the formation of a p-n junction between ZnO and Cu2S. The performance of ZnO/Cu2S nanotube arrays could be adjusted by changing the amount of Cu2S microcrystals.

Summary: Material properties are crucial for the efficiency and performance of optoelectronic devices like photodetectors, and we focused on fabricating a NiO/ZnO heterojunction with improved structural properties. By varying the spray solution volume, we investigated the influence of NiO and ZnO thickness on the structural and morphological properties using spray pyrolysis. Thicker NiO and ZnO films were found to be optimal for fabricating the desired heterostructure. Raman and XRD results confirmed the formation of the NiO/ZnO heterostructure, which exhibited smooth morphology without any pinholes. Further simulations allowed for studying the impact of structural properties on the photodetector performance.

Summary: In this study, the temperature-dependent electrochemical performance of different-concentration WIS electrolytes was investigated through Raman spectroscopy and molecular dynamics simulations. The 21 m WIS electrolyte showed advantages in the high-temperature range (>25 degrees C), while the 5 m WIS electrolyte exhibited superior low-temperature performance, maintaining a stable gel state even at -30 degrees C due to its muscular hydrogen bond network. The findings were further confirmed through the electrochemical performance evaluation of carbon supercapacitors assembled with different-concentration WIS electrolytes. This study provides guidance for choosing appropriate WIS electrolytes for electrochemical energy storage devices operating at different temperatures.

Summary: It is demonstrated that metal oxyhydroxides generated through surface reconfiguration during electrochemical processes can provide extra capacity besides the oxygen-anion intercalation in perovskite oxides. The strong Jahn-Teller distortion of Co2+ and Ni3+ in the pseudo trigonal prisms for the 2H-perovskite structure helps the formation of metal oxyhydroxides on the surface of the pristine material. Among the three 2H-perovskite related oxides, Sr5Co3NiO12-x with the highest Co2+ and Ni3+ contents exhibited the highest capacity increase. This study offers a promising pathway for the development of advanced perovskite-like oxide pseudocapacitive materials.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
