The synthesis of polyaniline doped with dodecylbenzene sulphonic acid (Pani-DBSA) coatings on 310 stainless steel (310 SS) surfaces has been investigated by using the galvanostatic method. The synthesized coatings were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), UV-Visible absorption spectrometry and Scanning Electron Microscopy (SEM...

The fact that oxidation, as one of the main routes of phase I metabolism of drugs, follows by conjugation reactions, and also formation of nitrenium ion as one of the clozapine oxidation products, directed us to investigate the oxidation of clozapine (CLZ) in the presence of nucleophile. The oxidation of clozapine (CLZ) has been studied on a glassy carbon electrode in the absence and presence o...

A twin-cell electrochemical filter is demonstrated to reduce the CO concentration in reformate hydrogen. In this design, the potential and gas flow are switched between the two filter cells so that alternative CO adsorption and oxidation occur in each cell while providing a continuous flow of H2 to a fuel cell. The effects of filter switching time and applied potential on the CO concentration o...

The electrochemical behavior of copper in 0.05 M HCl and 0.05 M NaCl carried out at open-circuit potential and at constant anodic potential after one hour has been investigated using electrochemical impedance spectroscopy (EIS) at 20 °C, 40 °C and 60 °C. The formation of copper chloride (CuCl) film does not protect copper from dissolution in the chloride media. The physical properties of the pa...

Free of tool wear, residual stress, and surface damage, electrochemistry plays a significant role in precision machining. We report here semiconductor polishing technique based on electrochemically induced chemical etching, which the concentration distribution electrogenerated etchant between electrode workpiece can be precisely controlled by pulse frequency potential applied to electrode. A th...

Electrochemical noise data is commonly used to monitor corrosion of metals in various environments. In this work we use recurrence plots to study electrochemical noise time series of stainless steel AISI 316 samples immersed in mildly corrosive electrolyte. It has been found that current and potential time series reveal different information. Recurrence quantification analysis of current time s...

The effect degradation in-service and in-laboratory conditions of the low-alloyed steels and aircraft aluminum alloys on its electrochemical conditions has been investigated. It is shown that the structural changes over degradation causes not only material embitterment, but also an activation of anodic and cathode electrode reactions and, correspondingly, a decrease of corrosion resistance. Suc...

DOI: 10.1002/aenm.201301329 Energy conversion and storage, [ 1–3 ] as the two most important technologies for energy, are usually two distinct processes that are performed by using two different and separated physical units, such as a piezoelectric nanogenerator and lithium-ion battery. [ 4–9 ] Recently, we presented a novel fundamental mechanism that directly hybridizes the two processes into ...

The paper presents a new system for electrochemical researches based on PC and LabVIEW software package. An overview of well known electrochemical methods, such as potential measurements, chronopotentiometry, chronoamperometry, cyclic voltammetry and EIS is given. Electrochemical impedance spectroscopy has been adapted for systems containing large capacitances. For signal generation and recordi...
