Abstract. The potentiodynamic experiments of the nickel effects on zinc electrodeposition have been done to understand impact Ni impurities electrowinning Zn from spent pickling liquor. chloride solutions concentrations 90 and 1 g/dm3 were used as electrolytes. latter was also mixed with in experiments. All runs carried out at room temperature 40 mV/s continuous polarization speed 1/s sampling ...

In situ monitoring of electrode materials reveals detailed physicochemical transition in electrochemical device. The key challenge is to explore the localized features of electrode surfaces, since the performance of an electrochemical device is determined by the summation of local architecture of the electrode material. Adaptive in situ techniques have been developed for numerous investigations...

A mathematical model is presented for the lithium intercalation of a single spinel particle as a microelectrode under the stimulus of a cyclic linear potential sweep. The model includes both lithium diffusion within the particle and kinetics at the particle/electrolyte interface. The model is used to predict that peak current densities depend linearly on the scan rate to a certain power with a ...

CHARACTERIZATION AND CORROSION OF BCC-TANTALUM COATING DEPOSITED ON ALUMINUM AND STEEL SUBSTRATE BY DC MAGNETRON SPUTTERING by Chirag Joshi Tantalum is one of the most versatile highly refractory corrosion-resistant metals. Tantalum coating can be used as an effective corrosion barrier if it is continuous, free from defects and it adheres well to the substrate. A DC magnetron sputtering techniq...

The inhibition efficiency (IE) of the hydrochloride salt chitosan biguanidine (CBG-HCl, a green organic compound) on stainless steel alloy (SS) corrosion in 0.5 M H2SO4 solution was documented this work. Data reported for electrochemical impedance spectroscopy (EIS) and potentiodynamic analysis confirmed increasing resistance presence CBG-HCl with synergistic effect KI. Potentiodynamic experime...
