A thin film of epinephrine (EP) was electrochemically deposited on the surface of glassy carbon electrode previously activated in NaHCO3 solution. The cyclic voltammograms of the modified electrode indicate that the surface confined EP are strongly dependent on the solution pH, as expected for quinone/hydroquinone functionalities. The EP-modified glassy carbon electrode exhibited...

In this study, the newly designed bipolar plate for proton exchange membrane fuel cells (PEMFC) was produced by spray-coating the Ni65Cr15P16B4 metallic glassy alloy on Al plate. The Ni65Cr15P16B4 metallic glass was adopted as a coating material because of its excellent corrosion resistance and the high velocity oxy-fuel (HVOF) spray coating was used for the metallic glass deposition on the Al ...

Metallic copper nanoparticles modified glassy carbon electrode is fabricated by reduction of CuSO4 in the presence of cetyltrimethylammonium bromide (CTAB) through potentiostatic method. As-prepared nanoparticles are characterized by scanning electron microscopy and electrochemical methods. Copper oxide modified glassy carbon electrode (nano-CuO/MGCE) is prepared using consecutive potential sca...

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to investigate the direct reduction of 5-chloro-2-(2,4-dichlorophenoxy)phenol (triclosan, 1) in dimethylformamide (DMF) containing tetra-n-butylammonium tetrafluoroborate (TBABF4). Cyclic voltammograms for reduction of 1 at glassy carbon electrodes exhibit three irreversible peaks attributed to successive reductive c...

A novel glassy carbon electrode modified by a gel containing multi-walled carbon nanotubes (MWNTs) and ionic liquid of 1-butyl-3-methylimidazolium hexafluorophosphate (BMIPF6) is reported. The gel is formed by grinding of MWNTs and BMIPF6. Such gel is then coated on the surface of a glassy carbon electrode. We have employed scanning electron microscopy, Fourier transform infrared spectrometry (...

The addition to the carbon ink, a major component of a screen-printed electrode (SPE), of an aliquot (10%) of Prussian Blue (PB)-modified glassy carbon (PB-GC) particles, resulted in an interference free “ready to use” amperometric H2O2 sensor (Vapp = −50 mV) with a LOD of 3 × 10−7 mol/l and a sensitivity of 135 mA (mol l−1 cm2). A storage stability of up to 8 months and an operational stabilit...

We present results of an ab initio molecular-dynamics study of glassy GeSe2 using a 216 atom model. The network topology of our model is analyzed through partial pair correlations, angle distributions, partial static structure factors, and ring structures. The total static structure factor and first sharp diffraction peak are in good agreement with experiment. The vibrational density of states ...

In this work, a simple and sensitive electrochemical method was developed to determine Sudan I by cyclic voltammetry and differential pulse voltammetry using a glassy carbon electrode modified with a chitosan/carbon nanotube composite. In cyclic voltammetry, Sudan I exhibited a well-defined oxidation peak located at 0.72 V at the multi-walled carbon nanotube (MWCNT)/chitosan-modified GCE. The d...
