An investigation was performed by using carbon fiber-reinforced polymer (CFRP) as the anode material in the impressed current cathodic protection (ICCP) system of steel reinforced concrete structures. The service life and performance of CFRP were investigated in simulated ICCP systems with various configurations. Constant current densities were maintained during the tests. No significant degrad...

We report on the systematic investigation of electropreconcentration phenomena in hybrid micro/nanofluidic devices. The competition between the electroosmotic dragging force and the highly nonlinear electrophoretic forces induced by the polarization effect is responsible for four preconcentration regimes within such structures that can arise at both cathodic and anodic sides of the nanochannel....

Voltage nonlinearity is a crucial performance parameter of MIM capacitors for RF, analog and mixed signal IC applications. In present work, the fabrication and characterization of anodic high-k MIM capacitors are reported in detail and modeling of nonlinearity coefficient of capacitance is developed using polarization of induced dipoles. The model agrees with experimental results for various hi...

We report on the magneto-optical properties of hexagonally arranged Ni nanowires embedded in anodic alumina templates. Due to the nanowire geometry, these samples show different response depending on the polarization orientation of the incident light, which leads to a high anisotropy of both their optical and magneto-optical properties. A strong increase of the magneto-optical activity is clear...

The focus of this work is to present test results on the bond steel-mortar interface undergoing stray current. strength, derived by pull-out tests, correlated electrochemical response steel rebar and properties mortar bulk matrix. effects curing regimes (in terms duration curing) starting point current are also investigated. It found that exerts degradation in all investigated cases, irrespecti...

The effect of laser surface melting on the corrosion resistance AZ31 Mg alloy in 0.1 M NaCl solution was investigated using different processing conditions (energy densities 14 and 17 J cm?2). Laser treatment induced rough surfaces primarily composed oxidized species Mg. XPS analysis revealed that concentration Al increased significantly as a consequence LSM. Electrochemical impedance spectrosc...

Aluminum anodes have been widely used in the cathodic protection of marine structures. However there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. Addition of alloying elements such as Zn and In not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra ...

Abstract: In chloride salt solutions, titanium alloys exhibit reasonably high pitting potentials as high as +10 V (vs. Ag/AgCl) at room temperatures. On the other hand, anodic pitting potentials are significantly lower in bromide solutions. In this study, pitting corrosion of commercially pure titanium in aqueous NaBr solution of 0.1 M concentration at room temperature was studied and the e...
