We describe the effect of electrode surface hydrophobicity on the electrochemical behavior and electrogenerated chemiluminescence (ECL) of Ru(bpy)3(2+) (bpy = 2,2'-bipyridyl)/tripropylamine (TPrA) system. Gold and platinum electrodes were modified with different thiol monolayers. The hydrophobicity of the electrode surfaces changed with different terminal groups of the thiol molecules. The oxid...

A new technique is proposed for paratubal electromyography, using a surface, non-invasive, electrode applied transnasally under nasopharyngoscope guidance. This electrode records activity of the tensor veli palatini muscle during swallowing. This technique is of interest for two reasons: endoscopic guidance offers the possibility to check correct positioning of the electrode recording at tensor...

Two natural clays (kaolinite and montmorillonite) were deposited onto a platinum electrode surface using two deposition techniques and under different experimental variables. For both clays, the percentages of surface coverage (%y) were optimized in the 75 96% range. A greater surface coverage was observed at higher temperatures for both clays, which confirms the endothermic nature of the depos...

Herein, gold nanoparticle had been successfully synthesized through a simple, inexpensive and clean electrochemical technique. Gold nanoparticles were directly deposited on the electrode surface using an electrochemical strategy. Then, the electrochemical deposition parameters (such as applied potential and deposition time) were optimized. 1.1 V and 250 s were applied as the optimal electrodepo...

Li metal negative electrode is expected for the next-generation Li battery electrode material, and the control of morphological variation of the Li metal electrode surface is very important issue. In-situ observation of the Li dendrite growth in an ionic liquid by an optical microscope was done in order to discuss the relationship between the Li dendrite growth and the Li ionic mass transfer ra...

A novel modified Ni-ZSM-5 nanozeolite was fabricated via an organic template-free hydrothermal route. The average particle size of Ni-ZSM-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. Then, Carbon paste electrode (CPE) was modified by Ni-ZSM-5 nanozeolite and Ni2+ ions were then incorporated to the nanozeolite matrix. Electrochemical behavior of this electrode was ...

The method used to immobilize the polymer on the Disodium ethylenediamine tetraacetate (EDTA) modified carbon paste electrode (CPE/EDTA) has proved its effectiveness for the detection and chelation of heavy metals in aqueous solution. Its complex formation with Pb(II) was examined by square wave voltammetry and cyclic voltammetry. CPE/EDTA electrodes are predisposed to the phenomenon of dissolu...

In this article, we report a newly devised composite electrode for electrochemical capacitors, by depositing manganese dioxide (MnO2) on the surface of carbon nanotubes via a spontaneous redox reaction. X-ray diffraction and transmission electron microscopic studies demonstrated a homogeneous coating of layered MnO2 on the surface of the carbon nanotubes. The MWNT@MnO2 composite electrode displ...

We employ a one-electron, tight-binding model of an electrode-molecule-electrode junction to explore the fundamental relationship between adsorption geometry and electron transport, producing exact results (within this model). By varying the chemisorption location (e.g., atop a surface atom or in a hollow site between surface atoms) and the molecule-electrode coupling, we find that the largest ...

The oxygen gas electrode has been studied for a number of mixed conducting oxide surface layers on top of Gd2Zr20 I (TGZO) solid electrolytes. In part II of this paper we present the results of frequency dispers on measurements for the electrode reaction, supplying additional information to the results of current-overvoltage experiments presented in part I. For both kinds of experiments the sam...
