Non-Thermal Plasma (NTP) Treatment of Alfalfa Seeds in Different Voltage Conditions Leads to Both Positive and Inhibitory Outcomes Related to Sprout Growth and Nutraceutical Properties

Plants
Non-thermal plasma (NTP) has proven to be a green method in the agricultural field for the stimulation of germination, growth, and production of nutraceutical compounds in some cases. However, the process is far from being fully understood and depends on

Plasma needle : non-thermal atmospheric plasmas in dentistry

, 2006
Who is not afraid of the dentist? Or to be more specific. . . who is not afraid of the dental drill? Caries is a common ailment, that is caused by bacteria in dental plaque. Cavities will form when you do not properly remove the plaque on your teeth.

Flow Diagnostics in Non-thermal Atmospheric Pressure Plasma Jets

, 2019
International audienceAtmospheric pressure plasma jets generate highly reactive species with lifetimes spanning orders of magnitude. Species flux, relevant for plasma surface interaction, strongly depends on generation and transport processes.

Sintering Kinetics of Plasma-Sprayed Zirconia TBCs

, 2007
A model of the sintering exhibited by EB-PVD TBCs, based on principles of free energy minimization, was recently published by Hutchinson et al. In the current paper, this approach is applied to sintering of plasma-sprayed TBCs and comparisons are made ...

The Influence of Gas Type and Flow Rate on Plasma Jet Length and Gas Temperature

Iraqi Journal of Physics
This study developed a plasma jet system using a power source that provides a high voltage of 10 kV and a total output power of 30 W. The system operates with three gases: air, nitrogen, and argon. The setup features a plasma torch placed within a steel

Tailoring supported olefin polymerisation catalysts using non-equilibrium plasmas [PDF]

, 1999
Supported olefin polymerisation catalysts are used to produce more than 20 million tonnes of polyethylene a year. In this thesis, the application of non- equilibrium plasmas to Phillips, Ziegler-Natta, and metallocene catalysts is described. A Cr(acetate)

Induction of cell growth arrest by atmospheric non-thermal plasma in colorectal cancer cells.

, 2010
Plasma is generated by ionizing neutral gas molecules, resulting in a mixture of energy particles, including electrons and ions. Recent progress in the understanding of non-thermal atmospheric plasma has led to applications in biomedicine.

Comparison of non-thermal plasma techniques for abatement of volatile organic compounds and nitrogen oxides [PDF]

, 1996
Non-thermal plasma processing is an emerging technology for the abatement of dilute concentrations of volatile organic compounds (VOCs), nitrogen oxides (NO{sub x}) and other hazardous air pollutants (HAPs) in atmospheric-pressure gas streams.

Simulation of a collisionless planar electrostatic shock in a proton–electron plasma with a strong initial thermal pressure change

, 2010
The localized deposition of the energy of a laser pulse, as it ablates a solid target, introduces high thermal pressure gradients in the plasma. The thermal expansion of this laser-heated plasma into the ambient medium (ionized residual gas) triggers the
