The inhibition effect of 2,4,6-tris (2-pyridyl)-1,3,5-triazine on corrosion of tin, indium and tin–indium alloys in hydrochloric acid solution
The influence of 2,4,6-tris (2-pyridyl)-1,3,5-triazine (TPTZ) on the corrosion of tin, indium and tin–indium alloys in 0.5 M HCl solution at different temperatures was studied. Potentiodynamic cathodic polarization and extrapolation of cathodic and anodic Tafel lines techniques were used to obtained experimental data. In the case of tin, the percent inhibition efficiency (IE%) increases as both concentration of TPTZ and ... إقراء المزيد

Effect of Extremely Low Frequency of Electromagnetic Fields on Some Toxic Species of Cyan Bacteria
This study investigates the extremely low-frequency electromagnetic fields (0.1-1Hz) on the growth of two species of toxic cyanobacteria with different habits including the colonial Microcystis aeruginosa and the filamentous Anabaena circinals, commonly found in drinking water sources. The results showed that Anabaena cultures exposed to ELF-EMF exhibited a sharp reduction in the cell numbers at frequency of 0.7, compared to ... إقراء المزيد
