Surface modification of polyamide by 50 Hz dielectric barrier discharge (DBD) produced in air at atmospheric pressure

open access: yesBibechana, 2021
Industrial applications of the dielectric barrier discharge (DBD) have a long tradition. However, lack of understanding in some of its fundamental issues, such as stochastic behaviors, is still a challenge for DBD researchers.

Generation of Atmospheric Pressure Dielectric Barrier Discharge (DBD) Using Water Electrode

open access: yesJournal of Nepal Physical Society, 2021
In this experiment, an atmospheric pressure dielectric barrier discharge (DBD) generated with a water electrode is investigated by means of optical measurements and imaging. The discharge was generated using a high voltage (0-20kV) power supply operating at 10-30 kHz with water as one of the electrode and borosilicate glass as a dielectric barrier of 2.
