A study has been presented on the effects of intrinsic mechanical parameters, such as surface stress, surface elastic modulus, surface porosity, permeability and grain size on the corrosion failure of nanocomposite coatings. A set of mechano-electrochemical equations was developed by combining the popular Butler-Volmer and Duhem expressions to analyze the direct influence of mechanical paramete...

In this work, electrochemical removal of hydrocortisone, a steroid hormone, from water using aluminum electrodes was investigated. The effects of many experimental parameters such as current density, electrolysis time, initial concentration of hydrocortisone, initial pH, electrolyte type and concentration, and distance between electrodes were studied. Moreover, the sludge formed was characteriz...

This paper focused on the characterization of electrochemical behavior of a martensitic stainless steel in the acidic solutions. For this purpose, electrochemical parameters were derived from potentiodynamic polarization, Mott Schottky analysis and electrochemical impedance spectroscopy (EIS) techniques. The potentiodynamic polarization results showed that corrosion current density of AISI 420 ...

A number of N-substituted benzimidazole derivatives have been synthesized and tested for their antibacterial activities. The chemical structures of the newly synthesized compounds were verified on the basis of spectral and elemental methods of analysis. Apart of this electrochemical analysis are performed on these derivatives. The electrochemical reduction of these compounds takes place in a si...

nanostructured alumina thin films were coated on stainless steel by sol-gel dip coating method. in order to prevent crack formation, al2o3 films were kept in a solvent bath immediately after coating to reduce the rate of drying. effects of calcination temperature and withdrawal speed on structural properties were analyzed using xrd and sem. topography and thickness of coatings were analyzed by ...

Polyvinyl chloride supported silver molybdate composite material is used to develop by solution casting method. This membrane was characterized by various instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) analyses. These characterizations are used to understand the functional groups,thermal sta...

The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...

In this work, a TiO2 nanoparticle modified carbon ionic liquid electrode (CILE) was employed as a sensitive sensor for the investigation of the electrochemical behavior of indomethacin (IND). This nanocomposite sensor has been fabricated by incorporation of TiO2 nanoparticles and the ionic liquid 1-hexylpyridinium hexafluorophosphate (HPFP). The surface of the electrode was studied by scanning ...
