Numerical Analysis of Metal Transfer Process in Plasma MIG Welding

open access: yesMetals, 2022
In plasma MIG welding, inert gas introduced from the torch nozzle is ionized in the upstream region of the MIG arc, which is termed “plasma”. This study aims to clarify the effect of the plasma on the metal-transfer process in the plasma MIG welding ...

Metal-Free Atom Transfer Radical Polymerization [PDF]

open access: yesJournal of the American Chemical Society, 2014
Overcoming the challenge of metal contamination in traditional ATRP systems, a metal-free ATRP process, mediated by light and catalyzed by an organic-based photoredox catalyst, is reported. Polymerization of vinyl monomers are efficiently activated and deactivated with light leading to excellent control over the molecular weight, polydispersity, and ...
