Summary: In this study, In2S3 nanosheet arrays were successfully grown on TiO2 films using a molecular precursor solution method, and the composition, morphology, and chemical valance states of the arrays were characterized using various techniques. Furthermore, the in situ growth of CuInS2 nanoparticles into the In2S3 nanosheet arrays led to the development of novel CuInS2 bulk heterojunction solar cells with a peak power conversion efficiency of 2.58% depending on the height of the In2S3 nanosheet arrays.

Summary: In this study, multishelled hollow structures (HoMSs) with different shell numbers, thicknesses, pore sizes, surface areas, and void sizes were successfully synthesized using carbon microspheres as a hard template and two different strategies: two-step strategy (TsS) and one-step strategy (OsS). The ZnO@TiO2 HoMSSs synthesized by OsS (triple shelled) exhibited excellent potassium storage capacity, rate capability, reversibility, and cyclic life in aqueous alkaline batteries, thanks to the thinner shell, larger pore size, high surface area, and bigger voids that provided a distinctive buffering zone for charge-discharge and improved the structural stability and cycling stability during the OH- intercalation/de-intercalation process.

Summary: In this study, a NiO thin layer was synthesized directly on a Ni sheet using ultra-short, pulsed laser irradiation in air. The layer had 3D nanostructures with high porosity and enhanced surface area, making it suitable for fabricating pseudo capacitive electrodes. The effects of laser parameters, such as scan speed and frequency, were analyzed. The results showed that a lower scan speed resulted in a larger surface area and a broccoli-like structure. The oxide layer was formed through a series of events, including energy transfer, heating, melting, evaporation, ionization, plasma formation, rapid quenching, and oxide layer formation, which occurred in ambient conditions within an ultra-short duration. The obtained oxide layer consisted of self-standing 3D nanostructures, with the active material directly growing on the substrate without the need for a binder.

Summary: In this study, MnCo2O4 nano-arrays with controllable morphologies were deposited on the surface of ACF using a hydrothermal route and an annealing process. The nanowire-shaped MnCo2O4@ACF binder-free electrode exhibited excellent electrochemical performance and the composite electrodes showed high energy density and power density. These findings suggest that the design of advanced electrode materials for high-performance supercapacitors could benefit from the fabrication of controllable morphologies and binder-free composite electrode systems.
