The inhibitive effect of apricot gum AG on mild steel in 0.5 M phosphoric acid solution was investigated by potentiodynamic polarization, electrochemical impedance spectroscopy EIS, linear polarization resistance and electrochemical noise EN techniques. The inhibition efficiency increased with increasing AG concentration up to a certain value and decreased with increasing temperature. Polarizat...

Reinforced concrete structures that are destroyed due to corrosion attacks need serious handling. One method of preventing is by using an inhibitor. In this study, the inhibitors used were tobacco leaf extract with variations 0%, 4% and 8%. The analyze rate occurs weight loss method. Tests carried out providing electricity test object a voltage 5V. results showed influence addition at concentra...

The mitigation of mild steel corrosion in 1.0 M H2SO4 solution by trimethoprim drug as a green and commercially available inhibitor was studied at room temperature using weight loss, open circuit potential, potentiodynamic polarization techniques. results showed that the investigated compound's inhibition efficiency depended on concentration nature inhibitor. found to increase with result indic...

Our recent study has indicated that Chinese green tea (Lung Chen), in which epigallocatechin-3-gallate (EGCG) accounts for 60% of catechins, protected cigarette smoke-induced lung injury. We now hypothesized that Lung Chen tea may also have potential effect on lung oxidative stress and proteases/anti-proteases in a smoking rat model. Sprague-Dawley rats were exposed to either sham air (SA) or 4...

The formation of hydrate plugs in oil and gas pipelines is a serious industrial problem and recently there has been an increased interest in the use of alternative hydrate inhibitors as substitutes for thermodynamic inhibitors like methanol. We show here that antifreeze proteins (AFPs) possess the ability to modify structure II (sII) tetrahydrofuran (THF) hydrate crystal morphologies by adherin...

Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. Many of the traditional anti-corrosion approaches such as the chromate process are effective but hazardous to the environment and human health. Mefp-1, a protein derived from blu...

The major constituent of green tea, (-)-epigallocatechin-3-O-gallate (EGCG), has been shown to have cancer-preventive and therapeutic activities. Numerous molecular targets for EGCG have been proposed, but the mechanisms of its anticancer activities are not clearly understood. In this issue of the JCI, Kumazoe et al. report that EGCG activates 67-kDa laminin receptor (67LR), elevates cGMP level...

Tara tannin is studied as an inhibitor of aluminum corrosion, immersed in aerated and near-neutral NaCl solution a wash-primer formulation. Electrochemical tests prove that tara tannins provide good corrosion resistance for aluminum, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy shows low formation products, absence Cl presence C. These results indicate act mixed-...
