2-Amino-N-benzthioazolyl benzamide (ABTB) was synthesized, characterized and used for thefabrication of a potentiometric sensor for Cu2+ metal ions. The electrode exhibits linear response to Cu(II) over a wide concentration range (4.79×10 -8 – 1.85×10 -1 M) with Nernstian slope of 30 ± 1.5 mVper decade. The electrode can be used in the pH range from 2 to 9. It has a fast response time of about1...

UNLABELLED We propose PEDOT PSS as a multi-functional composite material for an enhanced Li-air-battery air electrode. The PEDOT PSS layer was coated on the surface of carbon (graphene) using simple method. A electrode containing PEDOT PSS-coated graphene (PEDOT electrode) could be prepared without binder (such as PVDF) because of high adhesion of PEDOT PSS. PEDOT electrode presented co...

Renewable, cost-effective and eco-friendly electrode materials have attracted much attention in the energy conversion and storage fields. Bagasse, the waste product from sugarcane that mainly contains cellulose derivatives, can be a promising candidate to manufacture supercapacitor electrode materials. This study demonstrates the fabrication and characterization of highly porous carbon aerogels...

The electrochemical deposition and re-oxidation of solid carbon were studied in CO3(2-) ion-containing molten salts (e.g. CaCl2-CaCO3-LiCl-KCl and Li2CO3-K2CO3) at temperatures between 500 and 800 °C under Ar, CO2 or N2-CO2 atmospheres. The electrode reactions were investigated by thermodynamic analysis, cyclic voltammetry and chronopotentiometry in a three-electrode cell under various conditio...

Current methods for recording field potentials with tungsten electrodes make it virtually impossible to use the same recording electrode also as a lesioning electrode, for example for histological confirmation of the recorded site, because the lesioning procedure usually wears off the tungsten tip. Therefore, the electrode would have to be replaced after each lesioning procedure, which is a ver...

As a promising desalination technology, capacitive deionization (CDI) have shown practicality and cost-effectiveness in brackish water treatment. Developing more efficient electrode materials is the key to improving salt removal performance. This work reviewed current progress on electrode fabrication in application of CDI. Fundamental principal (e.g. EDL theory and adsorption isotherms) and pr...

Carbon materials such as activated carbon and carbon black are popular for use in electrodes for energy conversion and storage due to their conductivity and relative inertness. However, these materials are not thermodynamically stable and show various forms of degradation after long-term use [1]. Because electrode systems are inhomogeneous at a variety of length scales, improving performance an...

The present work describes the construction of a new modified electrode by casting the appropriate mixture of a metallocene, which has been introduced in the experimental part, as a mediator at the surface of glassy carbon (GC) electrode. The proposed modified GC electrode was used for the determination of ascorbic acid (AA) in phosphate buffer (PB) solution (pH = 4.0). When compared to bare GC...
