Al2O3-ZrO2 ceramic coatings were prepared on 6061 Al alloy by Micro Arc Oxidation (MAO) and Selective Laser Melting (SLM). Coatings MAO exhibit a porous structure progressive oxidation of the substrate as function processing time. Those made SLM are denser, although presence cracks is observed throughout their surface. XRD results suggest that coating consists m-ZrO2, t-ZrO2 γ-Al2O3 phases for ...
Background: In this work, a new method was developed for simultaneous determination of dopamine and rutin at glassy carbon electrode modified with CuO nanoparticles doped multi-walled carbon nanotubes (CuONPs–MWNT/GCE). This modified electrode has shown excellent electrocatalytic activity toward the oxidation of rutin in acetate buffer solution (pH=5). The modified electrode lowered the overpot...
a systematic study on the electrochemical behavior of the s-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (acda) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. all the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. controlled potential coulometry gave n=1 per mole fo...
In the present study, magnetic core-shell manganese ferrite nanoparticles (MCMNP) were synthesized and used for construction of a magnetic core-shell manganese ferrite nanoparticles modified screen-printed carbon electrode (MCSNP-SPCE). Cyclic voltammetry was used to study the electrochemical behavior of chlorpromazine (CPZ) and its determination was conducted by applying square wave voltammetr...
In the present work, thermal and mechanical behaviors of phenolic resin are investigated. This polymer can be used as a matrix for carbon-carbon composites. To find out the best heating process, five different cycles are used for curing the polymer and flexural strength of the specimens are obtained. The cycle with maximum strength is used for the next steps. Then, the oxidation behavior of sp...
The effect of anodic oxidation of a NiTi shape memory alloy in sulfuric acid electrolyte on its surface characteristics was studied. Surface roughness was measured by roughness tester. Surface morphology was studied using optical microscopy (OM) and scanning electron microscopy (SEM). Corrosion behavior was specified by recording Potentiodynamic polarization cur...
In the present paper, the electrochemical properties of magnetic iron oxide nanoparticles (Fe2O3 and Fe3O4) as highly sensitive sensors for the simultaneous determination of hydrazine and hydroxylamine was described. The electrochemical behavior of hydrazine and hydroxylamine was investigated using cyclic voltammetry, chronoamperometry and differentia...
In this study, pencil graphite electrode was modified using conductive polypyrrole (Ppy) and grapheme (GF) nanocomposite for electrochemical determination of insulin. Electrochemical behavior of insulin on PGE was investigated using cyclic voltammetric (CV) and differential pulse voltammetric (DPV) and chronoaprometry (CA) methods. Several effective parameters including pH, concentration, and s...
