in the present study, silver oxyfluoride modified silver electrode was employed to electrocatalytic oxidation of isoniazid. the process of oxidation and its kinetics were established by using cyclic voltammetry, chronoamperometry and amperometry techniques. the modified electrode shows a stable and linear response in the concentration range of 3×10−4 to 2.1×10−3 mol l-1 with a correlation coeff...

the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...

for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...

the combination of graphene (gr) and nickel oxide nanoparticles (nio nps) yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. in cyclic voltammetry (cv) studies, in the presence of ep, nio/gr composite modified electrode shows a significantly higher current response for ep oxidation. based on differential pulse voltamm...

background: the aim of this study was to measure the concentrations (levels) of serum total proteins and advanced oxidation protein products as markers of oxidant mediated protein damage in the sera of patients with oral cancers. methods: the study consisted of the sera analyses of serum total protein and advanced oxidation protein products’ levels in 30 age and sex matched controls, 60 patient...

medicinal plants have high importance in medicine and pharmacogonosy because of their secondary metabolites. essential oils, antioxidants and flavonoids are the major compounds of many medicinal plants. these compounds especially antioxidants can increase oxidation of dna in response to wounds. nowadays, progresses in biotechnology such as molecular markers were used for phylogenetic relationsh...

The oxidative modification of low density lipoprotein (LDL) may play an important role in atherogenesis. Antioxidants that can prevent LDL oxidation may act as antiatherogens. Our understanding of the mechanism of LDL oxidation and factors that determine its susceptibility to oxidation is still incomplete. Copper is a candidate for oxidizing LDL in atherosclerotic lesions. The binding of copper...

The suitability of hemp fibres as green support material for immobilization of Acidithiobacillus ferrooxidans cells in ferrous iron bio-oxidation process was investigated. A series of experiments were carried out in shake flasks and bioreactor for both cell immobilization and iron bio-oxidation. In flask experiments, five successive batch colonization cycles resulted in 6-fold increase...

In this study, aluminide coating was employed to enhance the high-temperature cyclic oxidation of Rene-80 superalloy at 950ºC. The microstructural aspects and phase constituents of samples were  investigated with scanning electron microscopy (SEM) and x-ray diffraction (XRD) techniques. The result of oxidation tests showed that the weight gain in the uncoated sample was considerably higher than...

In the present study, electrophoretic deposition (EPD) method in different electric fields (30 – 300 V / cm) was used to apply Co3O4 spinel coating to SUS 430 as SOFC interconnect. The coated and uncoated specimens were pre-sintered in air at 800 and 900 °C for 3 h followed by cyclic oxidation at 700 and 800 °C for 500 h, respectively. X-ray diffraction analysis (XRD), Scanning Electron Microsc...
