This paper presents the results of study that was undertaken to investigate the ability of a new antiscale, polyacrylamide in solving problems found in cooling water systems. The effects of the polymer on C-steel and copper dissolution in synthetic cooling water environment were studied through scale, Tafel, and Linear polarization measurements. The results obtained from this study showed that ...

Non–noble metal catalysts have recently emerged as promising alternatives to the expensive platinum catalysts for the oxygen reduction reaction (ORR). In this study, a new domain of materials, copper based coordination polymers, has been investigated as promising catalysts for ORR. The study was inspired by copper incorporating biomolecules, which efficiently catalyse the oxygen reduction react...

The phase formation of Ni-Ce composites onto a carbon steel electrode was investigated using electrochemical deposition. The anticorrosive properties of composite coating in 0.1 mol L HCl solution were studied by Tafel polarization and electrochemical impedance spectroscopy (EIS). Incorporation of CeO2 particles into the Ni matrices was found to improve corrosion resistance of pure Ni coatings....

Details are outlined of an electrochemical investigation of the oxygen evolution reaction (OER) at passive oxide covered polycrystalline Co electrodes in aqueous alkaline solution. Kinetic studies on electrodes subjected to different pre-treatment routines, yielded different values of the Tafel slope and the reaction order with respect to OH activity. Only one mechanistic pathway could account ...

Julius Tafel (Figure 1) was a Swiss chemist and electrochemist. started his scientific career working on the field of organic chemistry with Hermann Emil Fischer, but soon changed interests to electrochemistry after work Wilhelm Ostwald. Then, Tafel's concentrated compounds relation between rates electrochemical reactions applied overpotentials. name is presently associated many terms: equation...

Understanding the activity and selectivity of molecular catalysts for CO2 reduction to fuels is an important scientific endeavour in addressing the growing global energy demand. Cobalt-terpyridine compounds have been shown to be catalysts for CO2 reduction to CO while simultaneously producing H2 from the requisite proton source. To investigate the parameters governing the competition for H+ red...

In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...
