Summary: Memristor is a promising technology for future computing systems due to its low-power, high density, and scalability. However, there are still challenges to overcome, such as nonideal device characteristics. In this study, a high-performance memristor based on ITO/Ni single-atoms (NiSAs/N-C)/PVP/Au structure was developed, with improved switching speed and retention capability through the modulation of defect distribution and trapping level.

Summary: Rechargeable aqueous hybrid Zn batteries (HZBs) have gained attention for their low-cost, safety, and eco-friendly features. However, the lack of high-performance and stable cathode materials has hindered large-scale practical applications. In this study, Co1.29Ni1.71O4 nanowires (NWs) grown on nickel foam were found to exhibit reversible redox response and high catalytic activity for oxygen reduction/evolution reactions, thanks to their freestanding nanowire array structure. The HZB assembled with these NWs showed excellent cycling stability, achieving 6680 cycles over 2127 hours with a discharge capacity of 168.3 mA h g(-1) in KOH electrolyte. The HZB also demonstrated a flat discharge voltage plateau of -1.65 V, nearly 100% Coulombic efficiency, and remarkable rate performance. This work provides a promising approach to design and synthesize cathode materials for rechargeable aqueous HZBs.

Summary: A counter-tilted epitaxial growth technique was used to create a highly ordered three-dimensional crystallized crosslinked network structure of ZnO nanowires. The incorporation of Au catalysis induced both vertical and lateral growths, resulting in a unique crosslinked network growth. The shape and width of the nanowire network could be modified using a mixed ZnO/C vapor, allowing for the suppression of polar ZnO growth and promotion of nonpolar ZnO growth. This novel growth method enhances structural stability and provides a pathway for the development of large-scale, fast, and low-cost 3D network structures for electric and optic devices.

Summary: In the frigid winter, the ice and snow accumulation on high-voltage overhead power lines can pose serious risks to the reliability of electric power transmission and telecommunication systems. This study presents a scalable solar-thermal icephobic nanocoating that can effectively remove ice or snow from cables, even on complex curved surfaces. The nanocoating consists of a titanium nitride nanoparticle layer for efficient solar-thermal conversion and dual-scale silica particles for water-repellent properties at low temperatures. It demonstrates effective deicing/defrosting on power lines at temperatures as low as -15 degrees C. The versatility and compatibility of this coating make passive solar-driven deicing technologies promising for practical applications on outdoor exposed surfaces.

Summary: We investigated the effects of cubic and quartic anharmonicity on lattice dynamics and thermal transport in highly anharmonic BaZrO3 crystal. The anharmonic phonon renormalization plays a crucial role in determining the finite-temperature phonon energies and lattice thermal conductivity. The lattice anharmonicity induces low-frequency optical phonon hardening, which significantly suppresses phonon scattering rates and enhances the thermal conductivity, with an emphasized importance at elevated temperatures.
