In recent years, electrochemical supercapacitors have received considerable attention from many researchers. Metal oxides such as chromium oxide with high redox activity, high specific capacity, and excellent reversibility are suitable alternatives to ruthenium oxide in supercapacitor applications. In this study, first, graphene oxide (GO) was synthesized by the modified Hummers method. The syn...

In recent years, many studies have focused on the active materials of anodes to improve the performance of LIBs, while limited attention has been given to polymer binders, which act as inactive ingredients. However, polymer binders have amazing influence on the electrochemical performance of anodes. Herein, to investigate the binding performance between MCMB artificial graphite and the copper c...

Electrochemical biosensors have emerged as reliable analytical devices suitable for pathogen detection. Low cost, small sample requirement and possibility of miniaturization justifies their increasing development. Thus, we report in this review on the state of the art of avian influenza virus detection with genosensors and immunosensors working by an electrochemical mode. Their working principl...

The nature of the electrochemical responses from carbon nanotubes (CNTs), capacitive (physical), or Faradaic (chemical, also named p-doping or n-doping) remain controversial. In this chapter, the literature is reviewed and discussed trying to elucidate if some of the two processes prevails, how the presence of chemical reactions can be elucidated and which properties, specific from the chemical...

Site-specific electrochemical deposition is used to prepare polystyrene (PS)-Ag Janus particle arrays with superhydrophobic properties. The analyte molecules can be significantly enriched using the superhydrophobic property of the PS-Ag Janus particle array before SERS detections, enabling an extremely sensitive detection of molecules in a highly diluted solution (e.g., femtomolar level). This ...

Mesoporous carbon spheres (MCS) have been fabricated from structured mesoporous silica sphere using chemical vapor deposition (CVD) with ethylene as a carbon feedstock. The mesoporous carbon spheres have a high specific surface area of 666.8 m2/g and good electrochemical properties. The mechanism of formation mesoporous carbon spheres (carbon spheres) is investigated. The important thing is a s...

Polypyrrole nanoparticles were synthesized by chemical polymerization method using ammonium persulphate as an oxidant. The synthesized polypyrrole nanoparticles were characterized by FT-IR, UV-Visible, FESEM and CV. The structure of polypyrrole nanoparticles were confirmed by FT-IR spectroscopy. The UV-Vis spectra of polypyrrole nanoparticles show π-π* and n-π* transitions. The morphological pr...

Thermodynamic analysis and molecular dynamics simulations were conducted to systematically study the size-dependent electrochemical response of solids. By combining the generalized Young-Laplace equation with the popular Butler-Volmer formulation, the direct influence of surface stress on solid film electrochemical reactions was isolated. A series of thermodynamic formulas were developed to des...

The electropolymerization of 7,14-diphenylacenaphtho[1,2-k ]fluoranthene on a platinum or indium tin oxide (ITO) electrode produces an electroactive film which displays fluorescence and electrochromism. We report a study of the electrochemical properties and other characteristics of this film, such as the resistance dependence by the potential applied to the electrode. In particular, the film s...
