Abstract: In this research, the oxidation behaviour of high Aluminum heat resistant steel (%25Cr,%20Ni,%8Al) hasbeen evaluated at the temperature range of (1000-1300ºC).The results showed that there was no countinous healinglayer on the surface of the alloy when Al increased up to %5.5 and the oxidation resistance of steel decreased due toformation of spinel oxides on the surface.By increasing ...

the electrochemical oxidation of sulfamethazine (smz) has been studied at a multi-walled carbon nanotubes modified glassy carbon electrode (mwcnt-gce) by cyclic voltammetry. this modified electrode (mwcnt-gce) exhibited excellent electrocatalytic behavior toward the oxidation of smz as evidenced by the enhancement of the oxidation peak current and the shift in the anodic potential to less posit...

background: chlorophenols are classified as priority toxic pollutants. these acidic organic compounds present a serious potential hazard for human health and aquatic life. chlorophenols accumulate in water, soil and air due to high stability, and impart an unpleasant taste and odor to drinking water and can exert negative effects on different biological processes. among the different methods of...

Electrochemical oxidation of iodide has been studied in the presence of 2-thioborbituric acid using cyclic voltammetry and controlled-potential coulometry. The results indicate that, the resulting iodine takes part in halogenations reaction with 2-thiobarbituric acid. In addition, the present data are indicative of the suitability of iodide as a quasi mediator for determination of 2-thiobar...

In this paper Decision-making Orbital Health! (DOH!) will be described as a game derived from the basic functions necessary for BopIt! , a familiar game. that will ask the educational audience to respond to changing commands to Bop It!, Twist It!, and Squeeze It! The success of the new version of the game, will be that the Earth will be making these commands from Dynamic Planet, and the crowd a...

Methane oxidation associated with the belowground tissues of a common aquatic macrophyte, the burweed Sparganium eurycarpum, was assayed in situ by a chamber technique with acetylene or methyl fluoride as a methanotrophic inhibitor at a headspace concentration of 3 to 4%. Acetylene and methyl fluoride inhibited both methane oxidation and peat methanogenesis. However, inhibition of methanogenesi...

a simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (gce/cooxnps) for determination of butylated hydroxyanisole is presented here. the nanoparticles were fabricated by electrodepositing method. the modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in ph 12.0 phosphate buffer solution (pbs...

The combination of multi-walled carbon nanotubes and ionic liquid 1-octylpyridinium hexaflourophosphate (OPFP) yields a carbon nanocomposite (MWCNT-CILE) that can be well used aselectrode for electrocatalytic oxidation of venlafaxine (VEN). The influence of variousexperimental parameters including pH of the solution, the amount of multi-walled carbon nanotubeused for the modification of the car...
