Effect of plasma polarity on the synthesis of graphene quantum dots by atmospheric-pressure microplasmas

ABSTRACT: We confine the nanosecond repetitively pulsed discharge (NRP) to the micrometer scale, in a 200-µm discharge gap in air at atmospheric pressure and

In this talk, we will present results related with plasma polymerization, plasma deposition and plasma surface modification realized with an atmospheric pressure

The N atoms density distribution, Figure 3(b), shows, that depending on the Ar + ions velocity and molecular gas flows, relative densities between 10 −3 and 7 × 10 −2 has been

Figure 7 shows a sequence of 10ns exposure images taken throughout the positive and negative half cycles of the applied voltage whilst the plasma jet was operating in the bullet

Mass deposition rate for different jet powers and substrates, 4 mm distance, 180 s treatment time, N 2

The effect of electrostatic spraying (electro-hydro-dynamic atomization, EHDA) occurred when the high voltage was applied on the needle electrode [34]. We also used

We determine, and discuss, the first scaling law enabling the determination of the top jet drop size as a function of the corresponding mother bubble radius and the liquid

In this paper we combine different experimental diagnostic techniques (imaging, Stark polarization spectroscopy peak electric field measurements, Thomson scattering measurements
