Article: Researchers from Eindhoven University of Technology provide details of new studies and findings in the area of plasma science.

According to recent research from Netherlands, "This paper reports an experimental study of sub-microsecond pulsed discharges between a metal pin electrode and a tap water cathode in atmospheric pressure air. The dynamics of excited molecular and atomic species produced in the discharge is investigated by time resolved optical emission spectroscopy."

"The initial diffuse plasma constricts around 300 ns after the start of the voltage pulse. This constriction is correlated with an increase in gas temperature from 1000 to 5000 K and a strong increase in emission from O (777 nm), H-alpha and NH(A-X). The formation of OH(A-X) is discussed in the framework of OH (and ...
