The storage mechanisms of solid-solid supercapacitors based on graphene oxide (rGO/GO/rGO) were explored by Zhang Q et al. (Zhang al., 2014) [1], using Density Functional Theory (DFT) and Impedance Spectroscopy (EIS) to elucidate the unusual capacitive behavior GO sandwich films. Their study revealed alternating charged layers without diffusion zones. Analysis complex impedance (Z*) data, ranging from 10−3 3.106 Hz, was conducted an equivalent circuit, though this limited Nyquist plot data. To further investigate charge mechanisms, current delved deeper into conductivity (σ*). A theoretical approach identified relaxation processes in imaginary parts (Z″) (σ'') across frequencies. Extrapolation up 3.10^9 Hz deconvolution confirmed three distinct Z* σ*, similar Cole-Cole relaxation, which describes Maxwell-Wagner-Sillars (MWS) relaxation. This reflects local electrical interactions between active sites molecular chains counterions, creating induced dipolar moments or processes. relaxations at low, medium, high frequencies correspond well with DFT results, attributed specific regions: (GO), (rGO/GO) interface, reduced (rGO). Key parameters extracted each such as time, ionic strength, values different frequencies, showed good correlation. approach, deep (σ*) analysis, effectively highlighted conduction rGO/GO/rGO supercapacitor

Published: Feb. 12, 2025

Swimming pools, a globally popular recreational activity, necessitate effective disinfection to mitigate potential health risks arising from water contamination. Trichloroisocyanuric acid (TCCA), prominent disinfectant, is pivotal in pool treatment. This paper investigates the impact of trichloroisocyanuric concentration on electrical properties swimming water. Water samples were collected covered El Jadida, Morocco, disinfected with varying concentrations acid, and analyzed using impedance measurements. The pool's treatment system, including pre-filters pressure filters multi-layer beds, was described. Thorough examinations bromate, chlorate, chlorite conducted. obtained quality parameters met standard limits, indicating favorable conditions. complex conductivity different explored. An equivalent circuit model successfully described relaxation behavior, emphasizing intricate relationship between physicochemical Changes times DC observed increasing concentrations, providing valuable insights for optimization. nuanced understanding dynamics variations contributes optimizing maintenance strategies, ensuring safe enjoyable environment.
