a novel chemically modified electrode containing prussian blue complex was achieved on the surface of glass carbon electrode by sol-gel technique. the electrochemical behavior of modified electrode was characterized by cyclic voltammetry in detail. the film electrode obtained was very stable and exhibited electrocatalytic response for oxidation of nitrite. results showed at bare gc electrode, a...
Electrochemical behavior of a Prussian blue -modified carbon paste electrode and their applications to electrocatalytic activity for hydrazine oxidation. The electrochemical behavior and stability of the modified electrodes as well as electro-oxidation of hydrazine at the electrode were investigated using cyclic voltammetry method. At the modified electrode, the oxidation of hydrazine occurs ...
This study has examined the properties of Crofer 22APU stainless steel produced by mechanical alloying for using as interconnect plates in solid oxide fuel cells.This alloy was produced by mixing the source powders and mechanical alloying for 40 hours. For creating a sample with high density, spark-plasma sintering was applied at 1100 °C and 50 Mpa stress for 10 minutes. To achieve the des...
background diatomite coated by nanoparticles of copper and zinc mixed oxides were used to investigate catalytic oxidation of carbon monoxide. objectives aim of this paper was to investigatediatomite performance as a supporting host to confine the cuo and zno nanoparticles and its catalytic activity for carbon monoxide oxidation. materials and methods the prepared catalysts were characterized by...

Results from an ongoing study of the high temperature oxidation of intermetallic compounds in the Ti-Al system are presented. The oxidation behavior of alloys based on TiAl (y) has been found to be extremely complex depending on temperature and atmosphere composition. Protective alumina scales are formed in pure O2 up to a critical temperature above which a mixed Ti02/A1203 scale forms and grow...
In order to improve the oxidation resistance of ferritic stainless steel, it is possible to deposit a protective coating on steel substrate. In this research through the usage of pack cementation method a coating of titanium was applied on the surface of AISI 430 stainless steel. Scanning Electron-Microscopy (SEM), Energy- Dispersive X-ray spectrometry (EDAX) and X-ray diffraction (XRD) were us...
