Dewetting current

WebFeb 3, 2024 · Although the dewetting–rewetting transition is fully reversible over multiple cycles, the final dewetting pattern does not show any positional correlation over multiple dewetting cycles. Hence, the current approach to reversibly control the spinodal dewetting of thin liquid films underneath aqueous drops with an external electric field can be ... A related term sealing current (aka wetting current or fritting current) is widely used in the telecommunication industry describing a small constant DC current (typically 1-20 mA) in copper wire loops in order to avoid contact oxidation of contacts and splices. It is defined in ITU-T G.992.3 for "all digital … See more In electrical and electronics engineering, wetting current is the minimum electric current needing to flow through a contact to break through the surface film resistance at a contact. It is typically far below the contact's nominal … See more Contact cleaner can be applied to the contact surfaces to inhibit the formation of resistive surface films and/or to ameliorate existing films.
