High Voltage, EarlyView.ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety
High Voltage, EarlyView.ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Argon Cold Plasma Modification of Polyethylene Films to Tailor Surface and Barrier Properties
Journal of Applied Polymer Science, Volume 143, Issue 16, April 20, 2026.Argon cold plasma treatment of low‐density polyethylene (LDPE) and high‐density polyethylene (HDPE) films induces major changes in surface chemistry and morphology. Contact angles decrease significantly while surface energy increases, improving wettability. FTIR confirms the formation of polar functional groups, while pronounced etching, roughness, and

Pre-switching bifurcation of a slender jet [PDF]
, 2016 In this work, we study the near-field of the jet flow exiting a slot-model with aspect ratio 7.5:1. The core of the slender jet separates into two streams which subsequently merge recomposing a single core jet.
