Automated system for the synthesis of nanostructures via arc-discharge in liquids

Abstract: Submerged arc discharge in liquids has shown to be a promising method to synthesize a wide variety of nanomaterials. However, it requires an accurate arc current control to ensure the desired purity and structure of the products. A fluctuating arc current increases the dispersion in size distribution, as well as in the obtained nanoparticles structure pattern. Consequently, the arc current stability is essential to ensure the product homogeneity and quality. A system which ensures high stability of the arc dis… Show more

“…Not considering these elements could lead to trying to stabilize the arc at a current where it is not appropriated and having a different arc power for the same arc current. An electric stabilization element like a ballast resistor significantly improves the current and the power stability [45].…”

“…In some studies, electrodes were forced to approach each other at a constant speed to try to stabilize the discharge [34,44]. Based on automatic welding machines that move the electrode at a constant speed to obtain a uniform welding cord, and supposing that such movement could lead to a constant arc power or gap between electrodes, a constant speed control algorithm was tested in [45]. For better stability, this method was combined with electrode rotation [34].…”
