High Capacitive Ppy-SnO2 Nanocomposite anodes for treatment of methyl orange in photoelectro catalytic MFC. Bioresource Tech Reports.

Wearable and flexible electronics require compact, reliable power systems capable of delivering consistent energy for diverse applications. This study introduces a nanostructured PANI@CuMnO2 electrode material synthesized via mechanical grinding followed by hydrothermal treatment. The strategic integration of PANI into the CuMnO2 matrix enhances the material’s electrochemical performance, achieving a high areal specific capacitance of 355.62 mF cm?2 at 1 mA cm?2 and an energy density of 17.78 ?Wh cm?2 at a power density of 108 ?W cm?2 in a three-electrode system.

Since 1970, many artificial enzymes that imitate the activity and structure of natural enzymes have been discovered. Nanozymes are a group of nanomaterials with enzyme-mimetic properties capable of catalyzing natural enzyme processes. Nanozymes have attracted great interest in biomedicine due to their excellent stability, rapid reactivity, and affordable cost. The enzyme-mimetic activities of nanozymes may be modulated by numerous parameters, including the oxidative state of metal ions, pH, hydrogen peroxide (H2O2) level, and glutathione (GSH) concentration, indicating the tremendous potential for biological applications. This article delivers a comprehensive overview of the advances in the knowledge of nanozymes and the creation of unique and multifunctional nanozymes, and their biological applications. In addition, a future perspective of employing the as-designed nanozymes in biomedical and diagnostic applications is provided, and we also discuss the barriers and constraints for their further therapeutic use.

The application of carbon-based nanomaterials in energy storage devices has gained significant attention in the past decade. Efforts have been made to improve the electrochemical performance and cyclic stability by modifying existing electrode materials. Modern-day energy storage heavily depends on highly effective energy sources with high energy and power densities. Carbon-based nanomaterials like fullerenes, graphene, carbon nanotubes, activated carbon, and conducting polymers have received significant attention because of their distinctive hierarchical structure, high porosity, good mechanical and electrical characteristics, and extensive specific surface area.
