Abstract Corrosion inhibitors generated from plants and organic compounds are critical for achieving a greener environment. In this work we investigated the corrosion inhibition of pomegranate arils extract (PAE) mild steel in 1M HCl by potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), profilometry measurements. The effects PAE concentration (100, 200, 400 mg l –...

The inhibition performance of essential oil extracts citrus sinensis (CS) on the corrosion plain carbon steel (PCS) in 0.5 M H2SO4 and HCl solution was evaluated by weight loss measurement, potentiodynamic polarization technique, optical macroscopy ATF-FTIR spectroscopy. CS more effectively inhibited PCS compared to with optimal result 81.61% 76.95% from measurement. corresponding values are 94...

Abstract The corrosion inhibition of cow bone soot (BAS) at 5%, 10%, 15% and 20% weight on low carbon steel (LCS) in artificial concrete pore solution was evaluated with potentiodynamic polarization current-time displacement. BAS visibly decreased the rate LCS from 7.31 x 10 2 mm/y 0% to 1.45 concentration. Maximum performance 80.18% obtained mechanism determined be anodic type. Cathodic reduct...

in this paper we will prove that if $l$ is a continuous symmetric n-linear form on a hilbert spaceand $widehat{l}$ is the associated continuous n-homogeneous polynomial, then $||l||=||widehat{l}||$.for the proof we are using a classical generalized  inequality due to s. bernstein for entire functions of exponential type. furthermore we study the case that if x is a banach space then we have tha...

a simple method for fabrication of highly ordered gold nanorod film is introduced in this article. the procedure is based on thermal evaporation of gold into a porous anodic alumina film (paa). the ppa film was fabricated by combining the hard and mild anodization. this combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with control...

Artificial electrical stimulation that uses biphasic current pulses requires that the cathodic and anodic phases have zero biphasic mismatch. While biphasic mismatch should be minimized, a residual voltage appears due to charge leakage even for perfectly matched signals. Active anodic feedback methods control the charge in the anodic phase such that the tissue environment is electrochemically n...

The adsorption and electroadsorption of bromide from natural water has been studied in a filter-press electrochemical cell using commercial granular activated carbon as the adsorbent. During experiments, different voltages were applied (2 V, 3 V 4 V) under anodic conditions. presence electric field improves capacity carbon. decrease concentration observed at high potentials (3 or may be due to ...
