For COVID-19, chlorine has lately been utilised as a home disinfectant. Given that chlorine is hazardous to the human airway, the current research investigates the effects of chlorine mass fraction and droplet size on the human airway. The effects are investigated at chlorine mass ratios of 2% (24 ppm), 10% (120 ppm), 15% (180 ppm), and 20% (240 ppm), as …

In addition, chloride impeded the formation of passivation film, and the tendency to passivate decreased as the concentration of chloride in alkaline solution increased (Ref 19). Salvarezza et al. found that HS − and OH − had competitive effects, and acidification of an occluded battery led to incremental increases in Cl − and pitting corrosion (Ref 20 ).
The effects of chloride concentration, applied potential and time on the passive film of Cu-Zn-Ni ternary alloy in alkaline solution were systematically investigated using potentiodynamic and potentiostatic polarizations, electrochemical impedance spectroscopy, Mott–Schottky analysis, laser confocal microscopy, atomic force microscopy and x-ray …
A significant issue with ceramic capacitors is their propensity to crack under mechanical stress. At Redgarden, we typically limit the size of surface mount ceramic capacitors to 1210 (~0.12 x 0.10 inches). If larger capacitance values are required, we often use
For terminal conversion, the terminal amino groups of PA would react with acyl chloride groups of TMC and the unreacted acyl chloride groups would be hydrolyzed to form carboxyl groups. These increases of C–N and C O revealed the amide formation from the reaction between PA and TMC and the carboxyl generation from the TMC hydrolysis.
Using electrochemical analysis to analyze the solution, we were able to get a polarization curve. An initial potential of -0.4 V to + 0.4 V is required before beginning the positive potential scan. Scan rates of 10 mV/s were used in the work. Figure 3 demonstrates that the corrosion current of the electrode increases as the density of the Ni electrode on both lateral …

PCB capacitor and normal capacitor types behave alike as a capacitor is made up through 2 metal objects that are separated through non-dielectric materials. Thus, the combination of pads, PCB tracks, pins and components form capacitor that can destabilize frequency oscillation.
The electrolyte used, plays a crucial role in the electrochemical performance of supercapacitors. It is known that the concentration of electrolyte is also a controlling parameter for a given active material where the performance will be optimum for a particular concentration. Herein, we report a study on the effect of electrolyte concentration on the electrochemical …
