Having sufficient and accurate understanding about kinetics of phenomena, could be an important reason for further technological progresses. Finding a white-box mathematical model for weight vs. time curves of Electrophoretic Deposition (EPD) using large and small signal analysis has been studied thoroughly in the present investigation. Weight-Time curves of nano-Mullite suspension have been tr...

Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...

Modification of peptide on the electrode surface is very important issue for achieving valuable information from cell chip. In this study, various kinds of cysteine-containing peptide were fabricated on the electrode surface to enhance the electrochemical signals, cell spreading, and proliferation of rat neural stem cells. Different kinds of lysine-rich and RGD peptides were self-assembled on t...

The comb-shaped surface electrode has been designed to measure the signal from the tissue cultured with electric stimulation. The pattern of the thin film of the surface electrode was made of indium tin oxide (ITO) coated on the glass by the photolithography technique. C2C12 (mouse myoblast cell line) was cultured for 13 days on the patterned scaffold. The electric pulses (period 1 s, amplitude...

A simple physical model and theory have been proposed to investigate the electrocompression behavior of electrodeposited halide (chloride, bromide, and iodide) monolayer at the Au(111) electrode surface. By establishing the statistical thermodynamic formulas, the effective pair interaction energy, 2D spreading pressure, 2D isothermal compressibility, and electrode potential-coverage (θ-E) curve...

A novel carbon paste electrode modified with ionic liquid (n-hexyl-3-methylimidazolium hexafluoro phosphate) and magnetic core-shell manganese ferrite nanoparticles (MCSILCPE) was fabricated. The electrochemical study of the modified electrode, as well as its efficiency for electro-oxidation of tryptophan, is described. Cyclic voltammetry (CV), choronoamperometry (CHA) and square wave voltammet...

There is increasing interest in interfacing dissociated neuronal cultures with planar multielectrode arrays (MEAs) for the study of the dynamics of neuronal networks. Here we report on the successful use of three-dimensional tip electrode arrays (3D MEAs), originally developed for use with brain slices, for recording and stimulation of cultured neurons. We observed that many neurons grew direct...

A three-electrode based CO(2) sensor was fabricated using thick-film technology. The performance of this sensor was further enhanced by incorporating platinum nanoparticles onto the working electrode surface. An eight-fold increase in the signal output was obtained from the electrode with the platinum nanoparticles. The sensing output was linearly related to the CO(2) presented. Stability measu...

who had a mean PCV of 49.4% with a control group who had a mean PCV of 42.1 %. The mean TEI in the first group was 31.25 £2, which was significantly greater than that in the second group—27.5 n (P < 0.05) [5]. These observations may help to explain the "surprisingly increased response in TEI" noted by the authors. The influence of PCV clearly assumes greater importance with larger variations in...
