Polarization sensitive CARS in the absence of resonance enhancement is applied to a short chain protein. The minimum concentration to record polarization sensitive CARS spectra of protein solutions is estimated to be 10 mg/ml. The effects limiting the protein concentration are discussed and regarded from an experimental point of view. Signal strength and line parameters of polarization sensitiv...

The influence of the concentration of1-H-benzoteriazolon the corrosion of 316 stainless steel (SS) in chloride acid 1M solutions was studied. The potentiodynamics polarization and scanning electron microscopy (SEM) have been used. The inhibition efficiency increased with an increase in the concentration of1-H-benzoteriazol.The adsorption of1-H-benzoteriazol onto the SS surface occurs accord...

the effect of vanillin on the corrosion behavior of aa6061 al alloy in 3.5% nacl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (en) techniques. vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. the best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...

The corrosion inhibition of ST37 Carbon Steel in 1.0 M HCl by aquatic extract of coconut has been studied as a possible source of green inhibitor using the potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The aquatic extract of coconut have many advantages over classical techniques of sample preparation of plant gums (such as drying and solvent reflux).Pol...

Microstructure and corrosion performance of admiralty brass (ADB) and aluminum brass (ALB) alloys after passing different annealing heat treatments were investigated using optical and scanning electron microscope, energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), DC polarization measurements and electrochemical impedance spectroscopy (EIS). The results showed that heat tre...

The electrochemical behavior of 6063 aluminum alloy in ethylene glycol-water mixture was investigated by polarization curves and AC impedance measurements (EIS).  The results obtained from polarization curves showed that corrosion rate decreased with increasing ethylene glycol concentration. EIS data showed the decrease in the interface capacitance which caused by adsorption of ethylene glycol ...

Using a probe and procedure developed for the Abbott TOx analyzer, we investigated the influence of albumin on fluorescence polarization of amniotic fluid. Polarization readings increased when albumin was added to either “mature” or “immature”amnioticfluids. Albumin added to a fraction rich in lamellar bodies (10 000 x g pellet) greatly increased polarization readings, but albumin added to the ...

The effect of vanillin on the corrosion behavior of AA6061 Al alloy in 3.5% NaCl solution wasinvestigated using potentiodynamic polarization and electrochemical noise (EN) techniques. Vanillinoffers interesting possibilities for corrosion inhibition due to its nontoxicity and high solubility inaqueous media. The best inhibition effect at 200 ppm vanillin was a marked characteristic of theinhibi...
