In the present study, composites incorporating NiO-Co3O4 (NC) and CuO-NiO-Co3O4 (CNC) as active electrode materials were produced through hydrothermal method their performance was investigated systematically. The composition, formation, nanocomposite structure of fabricated material characterized by XRD, FTIR, UV–Vis. FE-SEM analysis revealed presence rod spherical mixed morphologies. prepared NC CNC samples utilized supercapacitor electrodes, demonstrating specific capacitances 262 Fg−1 at a current density 1 Ag−1. Interestingly, composite displayed notable long-term cyclic stability 84.9%, which observed even after 5000 charge–discharge cycles. exceptional electrochemical properties can be accredited to harmonious effects copper oxide addition, hollow structure, various metal oxides. This approach holds promise for development electrodes. These findings collectively indicate that hydrothermally synthesized nanocomposites exhibit potential high-performance electrodes applications.

Abstract Sustainable functionalization of bacterial cellulose for cost‐effective bionanocomposites with desired properties has received growing attention in recent years. This article presents the results work aimed at obtaining bionanocomposite materials based on cellulose, a natural and eco‐friendly material. Bacterial obtained from Kombucha symbiotic culture bacteria yeast (SCOBY) fermentation process is functionalized by embedding diatom frustules, silver nanoparticles (AgNPs), poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). The effects mechanical, optical, plasmonic, electrical, chemiluminescent, antimicrobial are evaluated. Morphological characteristics nanocomposites studied using electron microscopy. Addition frustules introduced into SCOBY media enhanced tensile strength increased ultraviolet (UV) blockage properties. In situ AgNPs tunes plasmonic chemiluminescent properties, revealing biosensing potential Modified shows activity experiments gram‐positive gram‐negative bacteria. Dual PEDOT:PSS improved electrical conductivity bionanocomposite. Overall, bottom‐up physical approaches resulting will open up new opportunities low‐cost production green contribute to development sustainable economy.

Abstract Due to the ubiquity of textiles in lives, electronic (E‐textiles) have emerged as a future technology capable addressing myriad challenges from mixed reality interfaces, on‐garment climate control, patient diagnostics, and interactive athletic wear. However, providing sufficient electrical power textile form factor has remained elusive. To address this issue, different approaches are discussed, starting with supercapacitors' advantages limitations material choices for textile‐based supercapacitors before discussing proper data analysis design considerations energy storage wearable electronics.
