Summary: The bi-functional activities of electrocatalysts for the ORR and discharge products decomposition in rechargeable Li-O2 batteries can be effectively evaluated using cyclic voltammetry with varying the lower potential limit. Utilizing Ru-Sn oxides decorated graphene nanowalls as examples, it was found that both Ru-enriched and Sn-enriched Ru-Sn oxides exhibit higher bi-functional activities than mono-oxides and pure graphene. The full cell performance in terms of rate capability, cycle life, and charge-discharge voltage gaps can be correlated to these findings.

Summary: In this study, Zr-substituted BiFeO3 thin films were fabricated using the spray pyrolysis technique, showing enhanced responsivity in the ultraviolet and visible regions of the solar spectrum. Optimum substitution of Zr4+ ions reduced oxygen vacancies and the optical bandgap. Structural analysis confirmed the rhombohedral phase of the films. The substitution of Zr4+ ions also reduced leakage current and enhanced remnant polarization. The AZO/BiFe0.95Zr0.05O3/PEDOT: PSS device achieved high responsivity, detectivity, and response time for different light sources. This work demonstrates that Zr substitution at the Fe-site enhances the optoelectronic properties of BiFeO3-based self-powered photo-detector heterojunctions.

Summary: In recent years, polymer-based nanocomposites have been extensively studied and utilized in tissue engineering for bone regeneration. These biodegradable nanocomposites have shown advantages in bone tissue cultivation and production. While some polymeric materials used in bone tissue engineering are biodegradable and bioactive, they often lack the required strength. Conversely, metallic implants are mechanically strong but pose risks of infection and secondary surgery. Polymer nanocomposites, on the other hand, possess bioinertness, low chemical reactivity, and the capability to mimic bone characteristics for orthopedic applications, offering potential solutions for bone abnormalities.

Summary: Due to the scarcity and lack of biodegradability of petroleum-based polymers, researchers are looking for green biopolymers as an alternative in the automobile and aviation industries. While automakers have successfully used bio-based materials in newer automobiles, the use of biopolymers in aviation is limited due to stricter property requirements. Advanced biopolymers are applied in various aircraft components, and these materials are expected to substitute traditional plastics with the help of modifying agents and cutting-edge manufacturing technology.
