Enhancement of soybean nodulation by seed treatment with non–thermal plasmas
(2020-03-18)
Soybean (Glycine max (L.) Merrill) is one of the most important crops worldwide providing dietary
protein and vegetable oil. Most of the nitrogen required by the crop is supplied through biological
N2 fxation. Non-thermal ...
Effects of non-thermal plasma technology on Diaporthe longicolla cultures and mechanisms involved.
(2021-01-05)
BACKGROUND: The Diaporthe/Phomopsis complex (D/P) is a group of soybean seed-borne fungi. The use of chemical fungicides,
either for seed treatment or during the crop cycle, is the most adopted practice for treating fungal ...
Cathode-sheath model for field emission sustained atmospheric pressure discharges.
(2021-03-16)
The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple
fluid model that takes into account non-local ionization. The effects of the ...
Correlation methods in cutting arcs
(IOPscience, 2011-05-25)
The present work applies similarity theory to the plasma emanating from transferred arc, gas-vortex stabilized plasma cutting torches, to analyze the existing correlation between the arc temperature and the physical ...
Langmuir probe diagnostics of an atmospheric pressure, vortex–stabilized nitrogen plasma jet
(2012-09-19)
Langmuir probe measurements in an atmospheric pressure direct current (dc) plasma jet are
reported. Sweeping probes were used. The experiment was carried out using a dc non–transferred
arc torch with a rod–type cathode ...
On the dynamics of cutting arc plasmas: the role of the power supply ripple
(ADVANCED ELECTROMAGNETICS, 2012-08)
The power sources used in cutting arc torches are usually poorly stabilized and have a large ripple factor. The strong oscillatory components in the voltage and arc current produce in turn, large fluctuations in the plasma ...
On the physical processes ruling an atmospheric pressure air glow discharge operating in an intermediate current regime
(2015-02-06)
Low-frequency (100 Hz), intermediate-current (50 to 200 mA) glow discharges were experimentally
investigated in atmospheric pressure air between blunt copper electrodes. Voltage–current
characteristics and images of the ...
Langmuir probe measurements in a time-fluctuating-highly ionized non-equilibrium cutting arc: Analysis of the electron retarding part of the time-averaged current-voltage characteristic of the probe.
(2013)
This work describes the application of Langmuir probe diagnostics to the measurement of the electron
temperature in a time-fluctuating-highly ionized, non-equilibrium cutting arc. The electron retarding
part of the ...
Cathode-sheath model for field emission sustained atmospheric pressure discharges
(2021)
The cathode-sheath region of a discharge in atmospheric pressure air with a flat copper cathode is numerically investigated by using a simple
fluid model that takes into account non-local ionization. The effects of the ...
Departures from local thermodynamic equilibrium in cutting arc plasmas derived from electron and gas density measurements using a twowavelength quantitative Schlieren technique.
(2011)
A two-wavelength quantitative Schlieren technique that allows inferring the electron and gas
densities of axisymmetric arc plasmas without imposing any assumption regarding statistical
equilibrium models is reported. ...
